The boom that 3D printing has experienced over the past couple years has been nothing short of astonishing. The industry started off as predominately as a backyard engineering operation, designing machines that’s sole purpose was to be able to print another one of itself, but it quickly escalated into the market we know today. Indeed it seems even the most wildest predictions about how it would revolutionize certain industries have come true with leading engineering companies adopting 3D printers for both prototyping and full blown production developments. With that in mind it was only a matter of time before one of them was bound for the International Space Station and yesterday SpaceX launched the first 3D printer to be based in space.
The printer, made by Made in Space, isn’t simply a stock standard model that’s been gussied up to work on the ISS. It’s been specifically designed to work in the microgravity environment in low earth orbit, undergoing thousands of simulated zero-g tests (presumably on one of NASA’s vomit comets). Whilst the specifications might not be exactly astounding when compared to some of the printers available down here on earth, it only has a print volume of 5cm x 10cm x 5cm with ABS plastic, it has the potential to be quite revolutionary for NASA, not to mention 3D printing at large.
One of the worst things about space travel is having to bring everything you need with you as there’s really no manufacturing capability to speak of in space. A 3D printer however provides the opportunity to ship up bulk supplies, in this case large reels of ABS plastic, which have a much greater density than the parts created with them will have. This drastically reduces the cost and complexity of shipping things up into space and provides a greater opportunity to create things in-orbit that might not be feasible to ship up otherwise. Of course whether or not 3D printing will be viable in space is another question, one which this device will attempt to answer.
There’s a lot of use for 3D printed plastic parts on the ISS, notably pretty much any small clip or connector on the interior of the craft, however I feel that the real usefulness of 3D printer will come when they can print with metal. Right now there’s no good solutions for doing that via the extruder (although there are a few out there using solder, which doesn’t have the greatest construction properties) as most use the powder bed sintering process. As you can probably guess having a bunch of powder in a microgravity environment isn’t going to work out too well so I’ll be interested to see how future space based 3D printers deal with metal and other materials.
It’s really quite exciting to see developments like this as there’s an incredible amount of opportunity for 3D printing to revolutionize several aspects of space travel. Indeed for long duration missions, one where component failure is a real risk, these kinds of in-orbit manufacturing capabilities are a necessity. Whilst we won’t be mass producing spacecraft parts in orbit any time soon these are the first few baby steps needed to developing that capability.
And wouldn’t you know it Planetary Resources already has partnerships in that direction. I should have guessed!
As of right now there’s only one way to get humans into space: on board a Russian Soyuz craft. It’s an incredibly reliable spacecraft, and probably one of the longest serving spacecraft ever, however it’s ability to only send up 3 astronauts at a time does limit it’s capabilities. Couple that with the fact that the going rate for a seat on one of them is about $70 million you can imagine why there’s an imperative on NASA to find another way to get themselves up there. Whilst there’s been a lot of internal work to develop the next generation of crew transportation NASA has realised that the private space industry will very soon have that capability. To that effect they created the Commercial Crew Transportation Capability (CCTCap) award, a $6.8 billion dollar contract to provide crew transportation services.
Today they announced the winners: SpaceX and Boeing.
The contract split gives $2.6 billion to SpaceX and $4.2 billion to Boeing. Considering NASA’s long relationship with Boeing it’s not surprising that they got a larger chunk of the pie (and the fact that they’ve already sunk about half a billion into the program already) however I’m sure SpaceX won’t be unhappy with that much business coming their way. Both companies are already well underway with their respective crew transports, Boeing with the CST-100 and SpaceX with the Dragon, which is likely why they were chosen in the first place. This program won’t replace the work that’s currently being done by NASA with the Orion capsule (under contract with Lockheed Martin) and will instead function as a supplement to that capability.
Being awarded work under CCTCap isn’t all roses however as NASA is looking to have at least one of the capsules up and running by 2017. That largely lines up with the timelines that SpaceX has for their Dragon capsule, with the first flights scheduled for late next year with crewed missions to follow shortly after. As to how that fits with the current CST-100 schedule is less clear as whilst there’s been some mockup tests done a couple years ago I haven’t seen much progress on it since. Boeing isn’t the same kind of company that SpaceX is though so there’s every possibility that the CST-100 is just as far along its development pipeline as the Dragon is. Still the CCTCap only calls for one of them to be ready by that time and if I was a betting man my money would be on SpaceX.
Both company’s solutions are of the reusable capsule variety which might seem a step backwards but it’s actually the smarter way to do space travel, especially if cost is a primary factor. The Space Shuttle, whilst iconic in its shape and unmatched in its capabilities, was a compromise between far too many objectives that were at odds with each other. If you’re goal is just getting people up and down then capsules are the way to go. It will be interesting to see if the economies of scale kick in with these craft as the Dragon is designed to be launched many times per year and the CST-100 can be reused up to 10 times before it needs a full teardown.
Needless to say this is an incredibly exciting announcement. I’ve long been of the mind that NASA should leave things like this to the private companies who can deliver the same service at a much better price without compromising on saftey. That then leaves them free to do the big picture stuff that will inspire the next generation, the kinds of things that we all remember the NASA name for. The CCTCap is the first step towards them rekindling that spirit and, as an avid space geek, that makes me so wonderfully happy.
The southern hemisphere isn’t much of a haven for the space industry. Some might say this is due to a lack of desirable launch sites (as the closer you are to the equator the bigger boost you get from the Earth’s rotation) however it’s more due to the economies just not being big enough to support them. I’ve often argued that Australia would make an ideal place to test innovative space technologies, mostly thanks to the large swaths of land that we have which aren’t good for much else, but we’ve only taken the first few cautious steps towards making Australia a space faring nation. However despite all this it appears that a New Zealand company, called Rocket Lab, is poised to kick start the space industry in the asia pacific region.
Rocket Lab was founded back in 2007 and was initially a producer of sounding rockets used to get small payloads to just beyond the edge of space. They made their first successful launch of their Ātea-1 craft in 2009 which then led onto them winning additional business overseas for various parts of the technology they’d developed as part of that program. The Ātea-1 was interesting because it was an all composite craft, being built out of carbon fibre rather than the more traditional metal structures that we see today. Whilst it doesn’t appear that the Ātea-1 has since been used in a commercial aspect Rocket Lab’s initial success attracted enough funding for them to pursue a bigger goal: a rocket capable of achieving orbital velocities.
The result of the last 5 years or so of research have resulted in what Rocket Lab are calling Electron, a scaled up version of their initial demonstration rocket that’s capable of putting at 110KG payload into a 500KM low earth orbit. The revolutionary thing they’re proposing with their rocket, apart from the construction, is a total launch cost of just under $5 million, a fraction of what it costs today. Whilst this might not be the sexiest of endeavours when it comes to space it is by far one of the most useful, especially when it comes to science missions that might not be able to afford the space on a larger craft. If they’re able to deliver on this then they’ll be in a market that’s woefully underserved, meaning there’s potential for a large revenue stream.
The two major competitors in this area are (or were) SpaceX’s Falcon 1 and the Orbital Sciences Pegasus. Unfortunately it seems that SpaceX has discontinued production of the Falcon 1 rocket in favour of launching multiple payloads aboard a Falcon 9 instead. This is actually good news for Rocket Lab as the Falcon 1 was in the same ballpark in terms of price ($6.7 million in 2007) with a slightly larger payload. The Pegasus on the other hand is still a cheap rocket comparatively, going for $11 million a launch, however its payload capacity is 4 times greater making it a much better bang for buck by comparison. Looking at the launch time frames however the Pegasus rarely launches more than twice a year which is where Electron will have it beat if it can deliver on its weekly launch schedule.
Unfortunately it doesn’t look like Rocket Lab has a hard date set for the first launch of Electron so we’ve probably still got a little bit of waiting ahead of us before we see the first of these blast off into space. Still the technology they’ve developed is quite novel and should they be able to deliver on their current promises there’s a bright future ahead of them in the small satellite market. Whether they then translate this into a grander vision of bigger rockets with all composite constructions will remain to be seen but for me I’m just excited to see the private space industry start to take off.
Even if it’s in my neighbour’s backyard, and not mine.
Ever since the retirement of the Space Shuttle the USA has been in what’s aptly describes as a “launch gap”. As of right now NASA is unable to launch its own astronauts into space and instead relies completely on the Russian Soyuz missions to ferry astronauts to and from the International Space Station. This isn’t a particularly cheap exercise, coming in at some $70 million per seat, making even the bloated shuttle program look competitive by comparison. NASA had always planned to develop another launch system, originally slated to be dubbed Ares and developed completely from scratch, however that was later scrapped in favour of the Space Launch System which would use many of the Shuttle’s components. This was in hope that the launch gap could be closed considerably, shortening the time NASA would be reliant on external partners.
News comes today that NASA has approved the funding for the project which is set to total some $6.8 billion over the next 4 years. The current schedule has the first launch of the SLS pegged for some time in 2017 with the first crewed mission to follow on around 4 years later. Developing a whole new human rated launch capability in 7 years is pretty good by any standards however it also begs the question as to whether or not NASA should be in the business of designing and manufacturing launch capabilities like this. When Ares and SLS were first designed the idea of a private company being able to provide this capability was still something of a fantasy however that’s no longer the case today.
Indeed SpaceX isn’t too far off deploying their own human rated craft that will be capable of delivering astronauts to the ISS, Moon and beyond. Their current schedule has the first crewed Dragon flight occurring no sooner than 2015 which, even with some delays here and there, would still have it happening several years before the SLS makes its manned debut. Looking at the recent Dragon V2 announcement it would seem like they’re well on their way to meeting those deadlines which will give the Dragon several years of in-flight usage before the SLS is even available. With NASA being far more open to commercial services than they used to be it does make you wonder what their real desire for the SLS is.
There’s an argument to be made that NASA has requirements that commercial providers aren’t willing to meet which, when it comes to human rated vessels, is mostly true. Man rating a launch system is expensive due to the numerous requirements you have to meet so most opt to just not do it. SpaceX is the notable exception to this as they’ve committed to developing the man rated Dragon even if NASA doesn’t commit to buying launches on it. Still the cash they’re dropping on the SLS could easily fund numerous Dragon launches, enough to cover NASA off for the better part of a decade if my finger in the air maths is anything to go by.
The only argument which I feel is somewhat valid is that NASA’s requirement for heavy lift outstrips pretty much any commercially available launch system available today. There’s really not much call for large single payloads unless you’re shipping humans into space (we’ve got an awfully long list of requirements compared to our robotic cousins) and so most of the big space contractors haven’t built one. SpaceX has plans to build rockets capable of doing this (the Falcon XX) although their timeframes are somewhat nebulos at this point in time. Still you could use a small portion of the cash set aside for the SLS in order to incentivise the private market to develop that capability as NASA has done quite successfully with its other commercial programs.
I’ve long been of the mind that NASA needs to get out of the launch system business so they can focus their time and resources on pushing the envelope of our capabilities in space. The SLS might fill a small niche that’s currently unserviced but it’s going to take its sweet time in getting there and will likely not be worth it when it finally arrives.
SpaceX’s Dragon capsule has proved to be an incredibly capable craft. Ever since it made it’s debut journey to the International Space Station back in 2012 the craft has made another 3 trips as part of the Commercial Resupply Services contract that SpaceX has with NASA. Should all things go to plan then 2014 will be the Dragon’s busiest year yet with a grand total of 4 launches planned, 3 of those to occur within a couple months of each other. Still the current Dragon is only half the puzzle for SpaceX as whilst it’s quite capable of delivering cargo to the ISS the human carrying variant has remained as a concept for quite some time. However that all changed last week when SpaceX announced the Dragon V2 capsule.
The original Dragon capsule was readily comparable to Soyuz and Apollo style craft, except for the fact that it couldn’t carry a single human into or back from orbit. The Dragon V2 on the other hand is really unlike any other craft, being able to carry up to 7 astronauts (equal to that of the Space Shuttle) and also with the capability to soft land anywhere on Earth within a very small area. That’s something that no other craft has ever been able to boast previously as even the venerable Space Shuttle required a runway to land and there were only 2 places on Earth capable of receiving it. Other notable improvements include fully automated docking and the world’s first fully 3D printed rocket engine, the SuperDraco.
Inside the capsule is when things start to get really impressive. however. If you’ve ever seen the inside of a Soyuz capsule you’ll know things are pretty tight in there and the Dragon V2 isn’t that much bigger. The interior design of the Dragon is where the big differences come in to play as you can see in the screen capture above. That giant screen flips down from the ceiling, making ingress and egress from the capsule extremely easy whilst at the same time providing a lot more room inside the capsule than you’d traditionally see in a craft of this nature. I’m guessing that they’re likely touchscreens as well, providing an incredible amount of flexibility in turns of what those panels can be capable of.
The ability to land anywhere in the world, even on land, is a pretty incredible achievement for SpaceX. Right now when astronauts and cosmonauts come back from space they come back on what’s called a ballistic trajectory, I.E. they’re falling to the ground like a rock. The Soyuz capsules have “soft landing” rockets which fire moments before they hit the ground to reduce the impact however they still get rolled head over heels several times before coming to a complete stop. The Dragon V2 is luxury by comparison, able to come to a soft landing right side up every time. Whilst many of the launches and landings will occur at the same places (due to orbital mechanics for the most part) the ability to land somewhere else, especially in an emergency, is an incredibly useful feature to have.
If everything goes perfectly we could see the first unmanned demonstration flight of the new Dragon capsule towards the end of next year with the first crewed mission coming in 2016. That’s likely to slip, something which NASA is prepared for as they have secured spots on Soyuz craft through 2017, but even that is a pretty incredible turnaround for a manned craft. Indeed SpaceX will achieved in under 20 years what many government agencies took far longer to accomplish and it seems like they have no intention of slowing down.
Bar our own planet Mars is by far the most studied planet in the solar system. Despite the fact that almost half the missions sent to Mars have ended in disaster we’ve still managed to do a whole lot of science there and our most recent mission, the Curiosity rover, has managed to capture the attention of millions worldwide. The next logical step would then be to send ourselves over there as whilst robotic explorers are great at specific tasks there’s a whole host of other things we could do if we had a few pairs of boots over there. Such a mission has been on everyone’s minds ever since we first set foot on the Moon over 4 decades ago but progress towards achieving it has been slow, verging on non-existent.
This is not to say that there isn’t interest in doing this. NASA currently has a mandate set by the Obama government to reach Mars by 2030 a goal which they’re actively working towards with the Space Launch System. SpaceX has also expressed a keen interest in doing something similar, albeit without help from NASA, in a much more aggressive time frame. Russia has also alluded to a revamp in their space program, primarily aimed at modernizing their current fleet, which could see them establishing a moon base and possibly flying a mission to Mars. However none of these have created the stir that the fully private Mars One mission and that’s probably for good reason.
For the uninitiated Mars One is a non-profit organisation that has the extremely ambitious goal of landing 4 people on the surface of Mars by 2023. They believe they can do this at a total cost of about $6 billion for the first 4 ($4 billion for the second lot) and plan to raise a chunk of that change through making a reality TV show based around the recruitment process. This is where it gets interesting/controversial as the application process is open to anyone and has already garnered 78,000 applications from around the world. In case you’re wondering no, I’m not one of them because I’m quite sceptical that they, or anyone really, could pull off this feat with the budget they’re claiming. I’d do a detailed breakdown of why this is so but I came across this article this morning that does a far better job of explaining it than I’d do.
At the same time Buzz Aldrin has just released his new book Mission to Mars: My Vision for Space Exploration which is the culmination of his many decades of experience and ideas for getting us humans to our red sister. Whilst I haven’t had a chance to read it I do know of many of the things he’ll be discussing in it (like the Aldrin Cycler) and they’re solid, realistic goals that could be achieved by NASA in the time frames he sets out. If you’re doubting his credentials Buzz has a Phd in astronautics and has done a lot of work for NASA that’s still in use today. Whether or not NASA, or any other space faring nation for that matter, takes his advice under wing will remain to be seen but I’m sure the book will make great reading regardless.
All that being said I do get the feeling that we’re starting to see the beginnings of a mini-space race, one that’s taking place between the private space industry and the super power governments of the world. It’s anyone’s guess who will emerge the victor from this but I’m just thankful that there are multiple entities all driving towards the same goal as the more players we have in the field the more likely it is to happen. I’m sceptical that we’ll see humans on Mars within the next decade but we’re likely to push the boundaries of human exploration further than has ever been done before, fixing us firmly on a path to our celestial sister.
It’s hard to believe that it was only 5 months ago that SpaceX launched its very first Dragon capsule that was part of the Commercial Resupply Services contract they had with NASA. It was an unqualified success with everything from the launch to capture and finally to docking going as smoothly as you could possibly expect. Even more impressive was the fact that they accomplished this feat no more than 5 months after their previous ISS rendezvous attempt aptly demonstrating that they are very capable of meeting their aggressive timelines, something which many hardened arm chair space nuts like myself were initially sceptical of.
Today brings news of another successful flight of the SpaceX Dragon capsule, dubbed CRS-2, which has just docked at the International Space Station. Just like previous missions it’s been loaded quite lightly carrying 677KGs of playload which is about 10% of its total combined (pressurized and unpressurised) capacity. The vast majority of this is taken up with science experiments with crew supplies and replacement parts making up the lesser half. This is also the first time that the unpressurised section of the Dragon capsule has been used which is where the spare station parts were contained. These will be unloaded during an EVA whilst the Dragon is docked at the ISS.
CRS-2’s flight up wasn’t without some significant drama that threatened to send it plummeting back to earth. Whilst the initial launch was fine and second stage separation was completed (an area in which SpaceX has had troubles in the past) 3 of the 4 rocket pods contained on the Dragon craft reported insufficient pressurization in their oxidizer system. This in turn triggered another safety system which stopped the solar panels from deploying, a safety mechanism designed to protect the craft in an unsuccessful booster stage separation scenario. In this state the Dragon would not be able to berth with the ISS and would likely end up plummeting back to earth in a most ungraceful fashion.
The Dragon’s internal systems were then overridden and the rocket pods were allowed to continue pressurizing. Shortly afterwards 2 rocket pods were deemed active and the solar panels were deployed. Not long after that all 4 rocket pods were reporting proper pressurization and were brought back online. Whilst not a catastrophic failure it did push back the schedule by a day meaning CRS-2 didn’t dock until early this morning.
With this most recent launch SpaceX has shown just how reliable they can be as they’ve hit a launch every 5 months for almost a year. It might not sound like much but comparing that to any other launch system demonstrates just how far SpaceX has come in the comparatively short time they’ve been a company. With this all in mind it’s looking pretty good that they’ll be able to make their 2015 deadline of putting people into orbit which, considering that the replacement from NASA is a long way off, is extremely impressive.
Cast your mind back 5 months, where were you then? I can remember where I was quite clearly: I was in a hotel room in a city called Bandar Seri Begawan, the capital of Brunei. With nothing much else to do in town apart from drink coffee and swelter in the unrelenting heat I had made myself comfortable on the bed with my laptop and tenuous Internet connection so that I could witness history in the making. It was there that I saw SpaceX’s Dragon capsule being captured by the crew aboard the International Space Station and brought to dock with the ISS, becoming the first ever private craft to do so.
SpaceX, not wanting to falter with their goal of being able to rapidly turn around craft, has today achieved the same feat again and the very first of their official missions, dubbed CRS-1 (Commercial Resupply Service), has just docked at the ISS. Just like its predecessor the payload its taking up isn’t anything to get excited about being mostly crew supplies, materials for new and current experiments as well as hardware for ongoing maintenance of the station itself. Just like its predecessor it will also be bringing back some payload back with it once its completed its 2 week mission attached to the ISS, something which is still a unique capability of the Dragon capsule.
Whilst the mission might be fairly rudimentary its launch has been anything but. Those of us who tuned into the launch live stream on Monday were treated to a pretty spectacular show due to the launch happening at night. There was also a curious incident where one of the engines appeared to suffer some kind of failure with many news outlets reporting that one of the engines on the Falcon 9 had exploded during the first stage. The failure didn’t appear to affect the launch however with the comms chatter saying everything was nominal and with the Dragon arriving successfully you can’t really fault them.
In fact the “explosion” was actually part of a system designed to relieve pressure in the engine bay when an engine out occurred. The system was triggered as the control systems aboard the Falcon 9 detected a loss of pressure in engine 1 and shut down the engine which lead to those panels being ejected in a rather spectacular fashion. To put this all in perspective the Falcon 9 can make it into orbit with 2 of its engines failing in this fashion and for many of the previous missions it has actually throttled down 2 of its engines because the additional thrust isn’t required. Thus whilst this was unexpected it was not a situation that they hadn’t accounted for and it was actually a great demonstration of the Falcon 9’s engine out capability, something which is currently unique to it (other launchers, which are no longer flying, have had this functionality).
A separate payload that wasn’t part of the CRS-1 mission is the prototype satellite for Orbcomm which was released once the Falcon 9 entered its second stage of flight. Whilst the payload was successfully released it was unfortunately dropped into the wrong orbit, much lower than the one required. Officials have stated that this was due to the engine out causing the other 8 engines to compensate, making them burn for longer than what was originally calculated for. Whilst they might be able to salvage it using the onboard propellant (which will reduce the useful life of the craft significantly) it’s still something of a faux pas on SpaceX’s part. I’m sure that for the next lot of flights it won’t be an issue as SpaceX has a phenomenal track record for fixing this problems as soon as they become apparent.
Despite these issues it’s still a great achievement for SpaceX to go from first dock to the ISS to being an official re-supplier all within the space of 5 months. Whilst they won’t make the deadlines that they originally had planned for this year (CRS-2 has slipped to be no earlier than January 2013) they’re still moving at a blistering pace compared to nearly all other players in the space industry. For now they’ll be slipping into the routine of launching cargo missions but it won’t be long before they start sending people up alongside the cargo and that’s an incredibly exciting prospect.
It was late Friday night. My companions and I had just finished up work as we stumbled out into the hot, humid air that surrounded us here in Brunei. After a nearly 12 hour day we had our sights fixed on grabbibng some dinner and then an early night as we would have to come in the next day to finish the job. As we chatted over our meals a curious image appeared on the television, one that I recognized very clearly as SpaceX’s Dragon capsule that was launched no more than a couple days earlier. At the time it appeared that they were performing some last manuevers before the docking would occur. I couldn’t take my eyes away from it staring intently at the capsule that was driftly serenely across the beautiful backdrop of our earth.
The time came for us to make our departure and we headed back to the hotel. I hit up Facebook to see what was going on when I saw a message from a long time friend: “I hope you’re not missing this http://on.msnbc.com/JxfRMS“.
I assured him I wasn’t.
I was fixated on the craft watching it intently from 2 different streams so that I’d never be out of the loop. I monitored Twitter like a hawk, soaking in the excitement that my fellow space nuts shared. I almost shed a tear when Houston gave SpaceX the go to make the final docking approach as, for some unknown reason, that was when it all became real: the very first private space craft was about to dock with the International Space Station. At 13:56 UTC on May 25th, 2012 the SpaceX Dragon became the first private space craft to be captured by the International Space Station and not 6 minutes later it was birthed on the earth side docking port of the American Harmony module.
It’s an incredible achievement for SpaceX and proves just how capable they are. This is only the second launch of both the Falcon 9 rocket and the Dragon capsule which demonstrates just how well engineered they are. Most of the credit here can go to the modularity of the Falcon series systems meaning that most of the launch stack has already seen a fair bit of flight testing thanks to the previous Falcon 1 launches. The design is paying off in spades for them now as with this kind of track record it won’t be long before we see them shipping humans up atop their Falcon rockets, and that’s extremely exciting.
The payload of the COTS Demo Flight 2 Dragon capsule is nothing remarkable being mostly food, water and spare computing parts and small experiments designed by students. What’s really special about the Dragon though is its ability to bring cargo back to earth (commonly referred to as downrange capability) something that no other craft currently offers. The ATV, HTV and Progress crafts all burn up upon re-entry meaning that the only way to get experiements back from the ISS now will be aboard the Dragon capsule. Considering that we now lack the enormous payload bay of the Space Shuttle this might be cause for some concern but I think SpaceX has that problem already solved.
Looking over the scheduled flights it would appear that SpaceX is looking to make good on their promise to make the launches frequent in order to take advantage of the economies of scale that will come along with that. If the current schedule is anything to go by there will be another 2 Dragon missions before the year is out and the pace appears to be rapidly increasing from there. So much so that 2015 could see 5 launches of the Dragon system rivalling the frequency at which the Soyuz/Progress capsules currently arrive at the ISS. It’s clear that SpaceX has a lot of faith in their launch system and that confidence means they can attempt such aggressive scheduling.
I have to congratulate SpaceX once again on their phenomenal achievement. For a company that’s only just a decade old to have achieved something that no one else has done before is simply incredible and I’m sure that SpaceX will continue to push the envelope of what is possible for decades to come. I’m more excited than ever now to see the next Dragon launch as each step brings us a little closer to the ultimate goal: restoring the capability that was lost with the Space Shuttle. I’ve made a promise to myself to be there to see it launch and I simply can’t wait to see when it will be.
Ah SpaceX, the one company that I simply can’t get tired of talking about. I think it’s because they’re just so different from the traditional way of launching things into space. Where the current players lavish billions of dollars and thousands of people at single projects SpaceX works on a skeleton crew and a shoe string budget. Where launch issues would cause others to delay by a day or more SpaceX can turn everything around in under an hour. They really are the embodiment of the start up thrust into the world of launching things into space and the entire industry is better off for having them around.
Last week saw SpaceX celebrate their 10th birthday. Now this isn’t news to many of us but it does put into perspective the kind of work these guys have been doing and how long they’ve been doing it for. In 10 years they’ve managed to design, build and successfully launch 2 different rocket systems, one of which has been launched multiple times. They’ve secured contracts with NASA to deliver supplies to the International Space Station and, should they be able to do that, they’ll push the envelope even further by being the first private space company to deliver astronauts to there as well.
The last week has also seen a swath of announcements from the now decade old space company. After several delays from NASA there’s finally a solid date for the first dock of one of their Dragon capsules, set for April 30th. The original (rather optimistic date) was in November last year but this time around it seems like all systems are go for this launch date. The launch window is small, only 4 days by my count, but with SpaceX’s track record of rapid fixes on launch days this window should be more than enough for them to get the Dragon capsule off the ground and on the way to the ISS.
SpaceX has also begun showing off the interior of the manned version of the Dragon capsule that can seat up to 7 astronauts at a time. For a capsule craft that’s pretty impressive as the Space Shuttle was only capable of carrying 1 more (albeit with a payload over 4 times that of an unmanned Dragon cargo craft) and the Russian Soyuz craft can only fit 3 in, and it’s still quite a squeeze in there. The Dragon by comparison looks to have quite a bit of room to it, indeed it’s quite comparable to the Apollo command module. It’s not specifically designed for a Lunar mission however, but there is another place that the manned Dragon capsule is well suited for.
That place is Mars.
The last, and probably most exciting, piece of news to come out of SpaceX this week is that the CEO Elon Musk has gone on record saying that he’d be able to do a round trip to Mars for around $500,000. The actual specifics of how they’ll achieve this are remaining a secret for now but Musk alluded to the fact that he has a plan for being able to refuel the craft on Mars, saving a major cost of having to truck all the fuel over there along with the payload. Whether he plans to do this with multiple launches (like launching another dragon ahead of them with the required fuel), some kind of fuel production plant on Mars or something else entirely though remains to be seen. The idea of doing a return trip to the red planet for that much though is really quite exciting and definitely something I’d consider ponying up the cash for.
SpaceX just seems to keep going from strength to strength as time goes on and this year will be no exception. The last 10 years have seen them grow from the start up that no one knew about to the new face of the private space industry. This year is looking to be a milestone year for them and I simply can’t wait to see what else they’ve got in store.
