SpaceX wants to beat NASA to Mars by 20 or so years

I just recently posted the graphic of NASA’s plans to put people on Mars in the 2040s. This article says 2030s, but 2040s sounds more like what’s coming out of the plans.

SpaceX has other ideas:

“Elon Musk, speaking to CNBC about how the future of humankind is rather closely tied to our ability to get off this planet, is ‘hopeful that the first people could be taken to Mars in 10 to 12 years’ — with SpaceX rockets and spacecraft, of course. This lines up with some of his previous comments about establishing a Mars colony in the 2020s. Meanwhile, NASA recently announced that it would try to put a human on Mars in 2035 — and only if it can secure the necessary funding and carry out a number of important milestone missions beforehand. Tantalizingly, Musk also spoke about SpaceX going public on the stock market — perhaps to raise the necessary funds to fly (and establish a colony?) on Mars.”

(Via SpaceX says it will put humans on Mars by 2026, almost 10 years ahead of NASA | ExtremeTech.)

The mention of SpaceX going public has me drooling. I was broke when Tesla went public, and I view it as too dear to trade now. Maybe I’ll have a little around when SpaceX goes public.

SpaceX Dragon 2 capsule

NewImage

I’m sure you’ve probably already seen this. But in case you haven’t, I’m looking at pictures of the Dragon version 2 capsule. This is the one that Elon Musk hopes to send astronauts up in sometime in the next couple years.

And in keeping with his focus on reusability, this one has parachutes as a backup. The main way it’s planned to land is by using rocket thrusters. So that it can be sent back up after being refueled. Thus, bringing costs down.

But also, that means it can be used on other planetary bodies for landing and taking off.

Interesting? Yeah:

Key to making the Dragon V2 cost-effective will be getting a lot of reuse out of it. According to Musk, the V2 is built to withstand 10 flights without any significant refurbishment. After that tenth flight or so, the heat shield would likely have to be replaced. On the V2, that shield is a variant of NASA’s Phenolic Impregnated Carbon Ablator, which SpaceX calls PICA-X 3 (it retains an X because it’s SpaceX’s variant, and a three because it’s the third version of such a shield.) But Musk said he expects that the next versions of PICA-X will last longer than the most current version. “It’s kind of like a brake pad, it does need to be replaced, but eventually we’d like to get up to 100 flights” out of the heat shield before replacement becomes necessary, he said, adding that SpaceX has improved the micrometeorite shielding on the Dragon V2, as well.

The Dragon V2 will be able to hold seven passengers as well as a ton of pressurized cargo, along with two to three tons of unpressurized cargo.

Orbital launches commercial space craft to ISS. Private space race officially on

NewImage

When the shuttle was canceled there was a lot of wailing and gnashing of teeth. But the SpaceX and Orbital solution has been cheaper and is looking solid.

Suck it haterz.

“At 10:58 EDT today, an Orbital Science Antares rocket took off successfully from NASA’s Wallops launch site in Virginia. Even as you read this, it’s flying a Cygnus into orbit in preparation for docking with the International Space Station in what is, so far, a seemingly flawless mission.

Orbital Sciences is part of the brand new space race between long-established names in space technology and younger, bolder new companies like SpaceX and Blue Origin. Orbital, along with SpaceX, was selected by NASA to develop and then use private rocket tech to deliver vital supplies to the ISS in the post-Space Shuttle era–a long lull before NASA’s own rocket systems are ready.”

(Via The Commercial Space Race Is On: Orbital Science Corp. Launches Rocket To Space Station | Fast Company | Business + Innovation.)

To be fair, in this race SpaceX is so far well ahead of Orbital. SpaceX will be launching later this month a mission that will develop a first stage that will attempt to do a test recovery and ‘landing’ over the ocean (a hover at least) to test the Grasshopper technology they’re developing.

Meanwhile, NASA own SLS program plods ahead. It’s cheaper than the space shuttle, but I still find it less interesting than the above:

“If we were to take SLS’s preliminary schedule of one cargo flight and one manned flight every other year, we get $1.2 billion for the cargo flight, and $2 billion for the manned one using Orion. A development cost of 12.6 billion dollars will have to be spread out over the total number of flights too, so if we use 30 flights like mister Strickland did we have to add $420 million to every flight. Over 30 flights, the average cost of SLS would be $2.02 billion per flight, though the number of cargo missions would probably end up dominating later on since most current Design Reference Missions would require more cargo then crewed flights. With a ratio of 2:1, we get a total of $1.89 billion per flight. If we take the costs of SLS only, not counting Orion, we get $1.6 billion per flight, which equals $18.000 per kilogram. “

SpaceX Grasshopper’s Divert Maneuver

Another important step in fine control of a reusable returning rocket stage:

“SpaceX proved yesterday that their Grasshopper prototype Vertical Takeoff Vertical Landing (VTVL) vehicle can do more than just go straight up and down. The goal of the test, said SpaceX CEO Elon Musk on Twitter was, ‘hard lateral deviation, stabilize & hover, rapid descent back to pad.’

On August 13th, the Grasshopper did just that, completing a divert test, flying to a 250-meter altitude with a 100-meter lateral maneuver before returning to the center of the pad. SpaceX said the test demonstrated the vehicle’s ability to perform more aggressive steering maneuvers than have been attempted in previous flights.”

Dragon Roadmap: From domestic crew independence to humans on Mars | NASASpaceFlight.com

NewImage

Something more cheerful and space-related than the grim past few days, a look at where Space X is along its path to human-certified launch:

“SpaceX’s Dragon spacecraft is continuing to make solid progress during the early years of its incremental roadmap, a path that has a firm focus on sending humans to Mars. With successful Commercial Cargo missions already under its belt, Dragon is already targeting the role of transporting NASA crews to the International Space Station (ISS).”

Commercial Crew Certification for private space access companies comes next year

2014 will be for certifying SpaceX, and Boeing for crewed flight, with actual crewed flight sometime after. Seeing as that NASA has Russian delivery set up through 2017, it looks like 2015-2016 will be the critical time for seeing whether either of those two companies can provide crewed service while they wean themselves (hopefully) over to the new crewed systems.

“Under NASA’s planned strategy, the next phase of certification (phase two) should start in 2014 and should include development, test, evaluation, and certification activities. It could also include, as options, a number of crewed missions to the ISS following certification.”

Paying Russia for astronaut launches just took money away from commercial crew plans, delaying missions

Here’s a Catch 22. In order to fund the commercial crew trips to the ISS using SpaceX or other contenders, NASA needs money. With budget cuts on the table, they had to take some of that money and send it to the Russians to keep the astronauts needed for ISS on track. Thus delaying the NASA ability to use commercial trips to 2017.

Frankly, I would have frozen the ISS visits until CCDEV is up and running, as that’s more critical long term, though I understand why this was done. You don’t really win here either way.

My hope is that SpaceX continues to innovate nonetheless.

“‘Because the funding for the President’s plan has been significantly reduced, we now won’t be able to support American launches until 2017. Even this delayed availability will be in question if Congress does not fully support the President’s fiscal year 2014 request for our Commercial Crew Program, forcing us once again to extend our contract with the Russians.”
