Paul Allen Launches Commercial Spaceship Project 152

smitty777 writes "The phrase 'Where do you want to go today?' takes on a whole new meaning as Paul Allen, Microsoft co-founder and the world's 57th richest man in the world, looks to create a new spaceship company. Stratolaunch Systems plans to bring 'airport like operations' to the world of private space travel. Partnering with Burt Rutan, the plan is to field a test within five years and commercially available flights within ten. Spacecraft will be air-launched from a giant, six-engined aircraft. There is more information available on the Stratolaunch homepage."

Currently, though, the notion that "private sector will solve all!" seems like more of an ideological excuse than an honest assessment of what the U.S. is capable of in space.

Not a lot of people realize this, but -all- DOD launches and all non-Shuttle NASA launches, plus of course all commercial satellite launches, have been on privately-built rockets for quite a few years now. This includes multi-billion dollar satellites critical to national security. It's somewhat nonsensical to have a separate government-designed/operated launcher just for manned US launches, especially when NASA hasn't successfully developed a launch vehicle in the past 30 years (plenty of failures, though).

If there's someone Lou Friedman should be complaining about, it's Senators Nelson and Shelby and their fixation on providing pork to large aerospace contractors in return for bribes, I mean campaign donations.

I would have hoped that someone in his position would be better informed, frankly.

Actually, while the summary doesn't mention this, this is pretty much exactly what Friedman says in his piece:

http://thespacereview.com/article/1947/1

Having caved in to Congressional special interests on the Space Launch System (SLS), the administration is now prepared to sacrifice science and exploration programs in order to prematurely start its development, with requirements that will neither be met nor needed for more than a decade.

Comment Re:No wear rockets? (Score 1) 227

It's worthnoting that the bulk of the mass and cost is in the first stage and its engines. For example, the Falcon 9 first stage has 9 Merlin engines and the upper stage only has one. This is even more extreme with the Falcon Heavy's 27:1 ratio. Reusing just the first stage might not get them a 100x cost reduction, but it should get them most of the way there.

Comment Re:This seems unlikely to work (Score 2) 227

This requires separate landing systems for each stage of the rocket. This is a lot more added mass. And the worst thing to add to a rocket is more mass. ... At this point, it doesn't seem that chemical rockets will become that more efficient barring major breakthroughs, like much lighter alloys, or totally new chemical reactions for the fuel. Neither of these seem very likely right now, and the second seems to be much less likely.

Actually, the Merlin engines SpaceX has been using have been getting more efficient, with the new engines providing 50% more thrust and a slightly higher ISP than their earlier engines. This extra capability is presumably what allows them to "spend" mass on things like VTVL landing systems and the required excess propellant.

Comment Re:Thanks, Space Shuttle (Score 1) 227

Actually, I'd argue that SpaceX has benefitted much more from NASA's efforts in unmanned exploration and low-cost space technology than it has from the much higher-funded Space Shuttle program. For example, SpaceX has used and improved on technology like the PICA heat shield material (now the PICA-X used on Dragon) and the principles from the Fastrac experimental low-cost engine were used in the first version of SpaceX's Merlin engine. I can't think of a single thing from the Shuttle program that has benefited SpaceX, unless you count it as an example of how -not- to design a reusable spacecraft.

Submission + - SpaceX Reveals Plans For Full Reusability (hobbyspace.com)

FleaPlus writes: At a talk at the National Press Club, SpaceX's Elon Musk revealed the company's plans for making their Falcon 9 rocket fully reusable. A rendering depicts the first stage, upper stage, and Dragon capsule all separately returning to the Earth's surface and making a controlled rocket-powered landing. During the next few years SpaceX will be testing VTVL maneuvers and reusability with their Falcon 9-based 'Grasshopper' testbed, with up to 70 test launches per year. Musk stated that if reuse is successful it would result in a 100x reduction in their already-low launch costs, a key step towards Musk's long-term aim of lowering the price of a ticket to Mars to $500K.

Comment Link to Grasshopper FAA report (Score 1) 67

For the curious, SpaceX didn't directly announce the Grasshopper themselves yet, but it was indirectly revealed for them via an FAA Environmental Assessment Report. The report can be read here.

Besides confirming that the Grasshopper rocket meets government requirements for environmental justice, minimal threat to endangered species, etc., there's plenty of interesting details about the rocket itself. Clark Lindsay listed several of these details here.

And yeah, this is most likely a testbed for reusing the first stage of their Falcon 9 rocket, as their initial attempts at reuse haven't panned out so far. It'll also give them valuable experience in creating software and controls systems for automated rocket-powered landing, which will be quite valuable for their eventual planetary landers.

IMO the goal of our space programs isn't just to put humans into space. It also serves to dump piles of money into US science an tech development. Our space program is an investment in the US that allows us to maintain a technological edge. We've lost hope of outproducing developing countries like China, out best chance now is to keep ourselves ahead of them technologically. We can't do that unless we are keeping our scientists and engineers working and advancing our sci/tech industry.

Not a lot of people realize this, but spending in technological research has actually been a fairly small portion of NASA's budget for quite some time, with far more money going towards things like paying for the standing army of maintenance personnel for the Space Shuttle.

In the past few years NASA asked for permission to spend $1 billion/year to revive technological research in NASA and invest in technologies needed to perform new types of exploration missions and perform existing missions more cost-effectively. Unfortunately, Congress wasn't a fan of the idea, IMHO because they weren't sure if the money would end up in the districts of Congresspeople who typically support the NASA budet. Instead, Congress diverted almost all the space technology money to building the SLS, an in-house rocket based on Shuttle-legacy technology. The two main features which have been politically touted for the SLS have been that it employees a large number of former Shuttle contractors and minimizes development of new technology.

The solution is for Congress to allow NASA to invest in research in space technology again, but it'll probably be a while before that happens.

Comment Re:Oh if only (Score 1) 291

Oh if only some other nation had something spaceworthy... Like a shuttle or so...

Funny joke, but Shuttle wasn't able to serve as an emergency Crew Return Vehicle due to limitations in in-orbit idle time. The Space Shuttle could only stay in orbit for a few weeks at a time, while the CRV requirement was for a half-year or longer.

Since the start of the ISS the only functioning CRV has been Soyuz. NASA had some attempts at building their own CRV, like the X-38 and Orbital Space Plane, but they were canceled back in the early 2000s. Commercial vehicles with CRV capabilities like Boeing's CST-100 and SpaceX's Dragon are under development, but it'll be a few more years before NASA allows their astronauts on them.

There's also NASA's Orion/MPCV, but its launcher, the Space Launch System, isn't due to be ready until 2017 or so.

Comment Re:Legal? (Score 4, Informative) 138

I hope they were in a state where wagering is legal. Otherwise, a public bet like that should be for token gifts and/or bragging rights.

I'm pretty sure these terms are legal in just about any state:

(1) Series production models of the Tesla Model S have to be delivered to paying customers before the end of 2012. (It was originally 2011, but Neil concedes that Tesla said it wouldn't make that date fairly early, and has since stuck to its 2012 date.)

(2) The Model S has to have seven passenger seats, certified as such by the National Highway Traffic Safety Administration, and earn a 4- or 5-star safety rating from the NHTSA.

(3) It has to have a battery pack that allows en-route swapping at a highway roadside station, similar to the Better Place battery swapping scheme.

(4) Model S prices must remain at the levels Tesla and Musk announced: $57,400 for the version with 160 miles of range, $67,400 for the 230-mile version, and $87,400 for the top-of-the-line 300-mile version (which will comprise the bulk of early production). All prices are before any Federal or other incentives.

If Tesla misses any one of those targets, Neil says, he wins the bet and Musk must donate $1 million to Médecins Sans FrontiÃres (Doctors Without Borders).

But if Tesla does what it said it will, Neil loses, and--being a journalist, not a multimillionaire entrepreneur--he will donate $1,000 to the same group.

Did I complain yet about the sound in space? Yes? Well, it is a pretty big fucking issue. Everything you need to know about the US can be summarized as a NASA science video having sound in space...

Sound doesn't get transmitted through space, but a microphone mounted on the rover would have easily picked up all the sounds in the video.
