Of course, there are several videos of the events. The press briefing before the unberthing:

The unberthing itself. Watch closely at the 5:40 mark and you can see the Draco thrusters fire in the first departure burn. It is just a small bright spot in the thruster bell.

The descent and splashdown video is fairly poor, but I still think it is interesting:

And last, but not least, a press briefing to wrap everything up:

While these unmanned cargo flights are certainly a major achievement, the next big step for Dragon is manned flight. SpaceX is working on the systems necessary to enable the Dragon to conduct manned flights, with an eye toward NASA’s Commercial Crew effort. With this successful flight Dragon is certainly the odds on favorite to be selected to carry crew to the ISS. But SpaceX isn’t the only company working on manned orbital vehicles.

Boeing is working on their CST-100, a manned capsule similar in concept to Dragon. The CST-100 is being designed for operations to the ISS, as well as the commercial stations planned by Bigelow Aerospace. They’ve been conducting drop tests of a boilerplate capsule (which means it is just representative of the shape and weight distribution, and is not the actual capsule design) to verify the parachute and airbag landing system:

Also in the hunt is Sierra Nevada Corporation with their Dream Chaser lifting body. The Dream Chaser looks more like a vehicle of the future than the capsule designs, something more appropriate for Buck Rogers or John Crichton. The basic shape is similar to NASA’s HL-20 concept from the 90s, and reaches back to the lifting body research programs of the 60s and 70s such as the HL-10, M2, and X-24. I have to say I’d really love to see the Dream Chaser become operational, if only because it looks like the future. SNC has been conducting captive carry tests of a test article in preparation for drop testing:

The vehicle builders aren’t the only ones working on future systems, NASA is preparing as well. The giant Vehicle Assembly Building (VAB), constructed for the Saturn V program and used for the Shuttle, is being thoroughly modernized to be ready for the next generation of rockets. Not only is it being redesigned to handle NASA’s own planned Space Launch System, but commercial rockets and spacecraft as well:

To wrap it all up, a recent episode of This Week At NASA included segments on SpaceX Dragon, Orbital Sciences Corporations Cygnus capsule (a competitor to Dragon for commercial cargo delivery to ISS, but not intended for crew), the Boeing CST-100, SNC Dream Chaser, NASA Space Launch System, and more:

I love the celebration at the end of the video once Dragon is in orbit and the solar panels have deployed. And an interesting contrast when they cut over to NASA’s ISS control room – a slightly different wardrobe for one.

Now the testing begins, hopefully culminating in a successful berthing at the ISS and a good re-entry.

EDIT: SpaceX posted the full hour long webcast from the launch:

In short, the flight computer aborted the launch at T?00:00:00.5. One half second before launch. It did so because it detected an abnormally high combustion chamber pressure on engine number five. And SpaceX has already diagnosed the problem – as they announced via Twitter:

Inspections found a faulty check valve on engine #5. We are replacing tonight. Next attempt Tuesday, 5/22 at 3:44 AM ET

As soon as the launch was aborted some critics started commenting on how this was a failure, and even that it shows commercial services aren’t able to supply the ISS, etc. Sure, this was a launch failure – the Falcon 9 didn’t launch, QED. But the rocket is intact and as SpaceX said they’ll be trying to launch again in a couple of days. It demonstrates that the design is sound in that it not only works when everything goes as planned – which is frankly the easy part – but it also handles anomalies.

The computer was able to detect the out-of-spec condition in the moments before launch and safely abort rather than launch and risk a catastrophic failure in flight. SpaceX’s hold-down launch system worked as designed and the rocket never moved an inch. The Falcon 9 was safed successfully, without any damage and is ready to fly again during the next launch window. That’s remarkable when compared to legacy systems. SpaceX designed multiple levels of safety and redundancy into not only the vehicle hardware and software itself, but also the policies and procedures. They’re doing it right.

Critics are quick to pounce on the ‘failure’, but how many failures have the legacy players had in their systems – including catastrophic failures? This is rocket science. It isn’t easy. While I was disappointed that the launch was aborted, it really shows the robustness of the system. And that’s a good thing, in the big picture.

So while it was a failure in the specific launch abort, it was a success in demonstrating the strength of the system overall. No one should expect SpaceX to get it right the first time, every time. There will be a learning curve. But things like this show that they’ve certainly done a lot to improve their odds.

I’m looking forward to the next attempt.

Also related to the SLS, the last of the 15 remaining RS-25D flight engines, formerly known as the Space Shuttle Main Engine (SSME), has been delivered to storage at Stennis. The plan is to use up the existing RS-25D engines on the expendable core stage of the new SLS before switching over to new-build, cheaper RS-25E engines designed to be expendable. The RS-25D has a number of features required in their role as reusable engines on the space shuttle which just aren’t necessary for an expendable engine. But the existing engines still have life left, so they’ll go out in a blaze of glory on one last mission on the SLS.

In more immediate news, the SpaceX COTS 2+ Mission, aka Falcon 9 Flight 3, which has been rescheduled a few times is now set to launch this morning, Saturday, May 19, at 04:55ET. This will be the first launch of a commercial spacecraft, the Dragon capsule, to the International Space Station. A truly historic event – and they have a live webcast on YouTube! It is set to start at 04:15ET – you can join now, there is a timer counting down to the start of the webcast:

And for something different, the recent Lyrid meteor shower as filmed from the ISS:

There isn’t a lot to see in the video, the test firing only lasts for two seconds before the planned abort. I still think it is fun to watch, and it shows just how sparse SpaceX’s pad infrastructure is. When they start manned flights of the Dragon I suppose they’ll need a more traditional service tower for crew access.

I’m excited for the mission, while at the same time trying to temper that with the knowledge that it is very much a test flight and there is a good chance it won’t go off as planned. But if anything does go wrong SpaceX is committed to learning from the mission and trying again, just as they did with the first few Falcon 1 flights which, while failing as a larger mission, we successful as instructive test flights, leading to eventual success. And ultimately to the successful flight of the Falcon 9 and Dragon.

Good luck and godspeed, SpaceX!

The concept combines a massively scaled up version of the White Knight Two carrier aircraft for SpaceShipTwo with a rocket that looks like the love child of SpaceX’s Falcon 9 and Orbital Sciences’ Pegasus XL. This isn’t just a pie-in-the-sky idea, they have some serious leadership on board. And Scaled Composites and SpaceX both have proven track records of success, and of pulling of audacious plans that many expected to fail, so I wouldn’t bet against them. And I wouldn’t expect them to be involved if they weren’t serious.

The design of the system is no coincidence, Paul Allen worked with Burt Rutan and Scaled Composites to build the original White Knight One and SpaceShipOne, so they’re adapting a design they have experience with. The rocket actually is a variant of the Falcon 9, known as the Falcon 9 Air. Based on the renderings it looks a bit more like the stillborn Falcon 5 with a wing – given it is shown with five motors and not nine. But if you’re going to launch from altitude you don’t need as much initial thrust as you’re already part of the way ‘up hill’ and have less atmosphere to push through as well.

They haven’t released many specifics, but they did release some general information. The carrier aircraft is to weigh 1.2 million pounds – one has to expect that’s the loaded weight – with a 385 foot wingspan. It will use six “747 engines”, which is quite vague as the B747 has used a variety of engines over its life. It could be the B747-8′s new GEnx-2B engines, which have 66,500 pounds of thrust, or the next most logical would seem to be the B747-400′s GE CF6-80 or P&W 4062 with 62-63k. It strikes me as oddly specific and yet vague at the same time really. I’m sure there is some design consideration driving it and not, say, four GE90s of the B777. The carrier will be able to carry the rocket up to 1,300 miles from the departure point which allows for optimal positioning for the launch. Though the selection of departure points will be limited, as it requires a runway 12,000 feet long – minimum.

The rocket, as I said, is a derivative of the Falcon 9. It will way approximately 500,000 pounds at launch and will be approximately 120 feet long. Launch will happen at around 30,000 feet. Lots of approximates.

Flight testing is expected to begin in 2016, so we have a few years before we’ll see this beast flying. Initial launches will be for cargo, but they plan to use the system for manned orbital launches eventually. I really hope they pull it off because, well, damn.

Now let’s scale this up to air launch a Falcon Heavy.

Spotted via Aviation Week’s On Space blog.

The SLS will initially use the RS-25D, also known as the SSME – or Space Shuttle Main Engine. NASA has a stockpile of these from the shuttle program. Later this will change to a cheaper RS-25E, or expendable, version. Whereas the RS-25D was reused on multiple shuttle flights, engines used on the SLS will be discarded. So there is no need to build the engines to higher standards for reusability. NASA is only using the RS-25D initially since they already have a stockpile of them and with the retirement of the shuttle they have nothing else useful to do with them. The RS-68B the Ares V was to use would’ve been a version of the RS-68/68A already in use on the Delta IV launcher, designed to be expendable.

Most of the increased lift from the evolved version of the SLS will come from new rocket boosters. NASA is expected to compete the design of the new boosters, which could be liquid or solid fueled. But that is still a ‘when and if’ question, since they need to get the initial design off the ground first.

I’m disappointed because I grew up with one program after another promising great leaps. The X-30 National Aerospace Plane – cancelled. The DC-X Delta Clipper – cancelled. (Though Jeff Bezo’s Blue Origin New Shepard program looks to be the spiritual successor.) The X-33 VentureStar – cancelled. The X-34 – cancelled. The X-38 Crew Return Vehicle – cancelled. And, of course, the Constellation Program was cancelled.

At least the Air Force picked up the X-37 after NASA dumped it.

With each cancellation the programs have seemed to get less ambitious. No more space planes, reusable launch vehicles, etc. We’re back to the gumdrop on a stick capsules. Much of the technology in the SLS can trace its development right back to the Apollo program, and the rest is a pretty direct link to the shuttle. There’s not much that can be considered new. That’s safe and (relatively) cheap, but not all that inspiring, at least to me. The first generation SLS reminds me very strongly of the aborted Ares IV concept, which would’ve been kind of a combination of the lower stages of the Ares V and the upper stages of the Ares I.

Frankly I’m a lot more inspired these days by what’s going on in the commercial sector. And I don’t me the traditional giants like Boeing, Lockheed, Ariane, the Russians, etc. But the space start ups that are doing new things. Blue Origin and their New Shepard, as well as their other projects. Sierra Nevada and their Dream Chaser space plane (based on concepts from the cancelled NASA HL-20). But most especially Elon Musk’s SpaceX and their Falcon launchers and Dragon capsule.

SpaceX’s Falcon Heavy is being designed to lift 53 metric tons to LEO. With concepts for the Falcon X Heavy and Falcon XX lifting 125 and 140 metric tons, respectively. While those are still concepts the Falcon 9 has already flown, and the Falcon Heavy is a direct evolution of the Falcon 9 (it was formerly known as the Falcon 9 Heavy) and it is in active development. While it won’t lift even as much as the first generation SLS, I find it more inspirational because it is a small private company developing everything from scratch. There is no legacy technology in the Falcon program, they’ve been inventing a new generation of rocket technology. And so far they’ve been very successful.

While the SLS will surely be a very impressive vehicle if it ever flies, don’t get me wrong, right now that is a very big if given NASA’s track record with programs. I’m not sure we wouldn’t be better off giving the money to companies like SpaceX to accelerate development of vehicles like the Falcon XX. Given their track record on the Falcon 1, Falcon 9, and Dragon to date we might get more for less.
