India Planning Reusable 2-Stage-to-Orbit Vehicle
WoodenKnight writes "India's ISRO Chairman, G Madhavan Nair recently gave a brief description of a fully-reusable 2-stage satellite launch vehicle that is being planned at ISRO. From the article: 'This is in its initial stages of vehicle configuration and the first stage is configured as a winged body configuration, which will attain an altitude of around 100 km and deliver nearly half the orbital velocity. This stage after burnout will re-enter and will be made to land horizontally on the runway, like an aircraft. The second stage after delivering the payload in the orbit will be made to re-enter the atmosphere and will be recovered using airbags either in the sea or land. This is only in its conceptual stage.'"

Wow.
Doesn't this sound like a Space Shuttle?
Sounds a good deal like Spaceship One.
Maybe its better than firing rockets straight up.

NASA's stuff to India now?
I think they can spend that money a tad more wisely.
In fact we will

I've not spent much time on the issue of space -- I do want to go, and I will pay almost anything to do so in my lifetime.
My question is -- why do all these innovations come from governments? Are there regulations or requirements that prevent private investment into the new inventions?
Space tourism will be a huge business. Just from discussing it with customers of mine (who pay $150,000 for a week in Vegas for 2 people, what's $150,000 to hit space?), I bet there are at least 100,000 people in the world who would pay $50,000 to travel.
I just can't see why a country has to pay for space research. India is gaining wealth, does that mean taxing the new business owners to go to space? How about stopping that, and letting these new business owners be the ones who want to go to space and fund it themselves?
For anyone who has done more research than I could, what are the obstacles to private research? There's a market, there's a will, so there must be a way. Who is putting the kibosh on it?

"Beware of he who would deny you access to information, for in his heart he dreams himself your master."
AND why the US supports it: India considers its missile, space and nuclear programs to be closely interlinked, with nuclear deterrence against Pakistan and China and benefits to the people through satellite technology and nuclear energy being critical factors.
Oh, fuck, does this mean there's another Cold War starting? If so, I agree with my sig.

NASA and others have talked about similar designs in the past; it's definitely a reasonable way to go.
SpaceX is hopeful that at least some of the Falcon variants will be fully-reusable, although they haven't been saying that as loudly as they've said that they think the first stage of every Falcon variant will be reusable. (All of the Falcons will be two stage vehicles.)
If Falcon 9 works (big "if," since even Falcon 1 hasn't gotten in to orbit yet) I suspect it will own a huge fraction of the world launch market within five to ten years of first flight. They'll be able to launch any current satellite model, and I doubt that even the Russians will be able to launch for similar prices w/o massive changes in their launch business.
I hope the Indians pursue a two-stage concept... it's a good concept, and I'd love to see more good launch options.

Sure, India has a long way to go. But the country has some of the world's best scientists and has become a significant center for global technological innovation. Why shouldn't they put their skills to work in space?
Of course, it all may be about ego, about promoting national pride. Americans, though, are hardly in a position to judge others about that. After all, our entire space program was built on beating the Soviets to the moon!
If you build it, they will come...
Indians will use this to make money, right? This isn't some ego-building thing like the Chinese space program, right?
I think that's really neat. I can imagine the Chinese govt. has something to prove. I can also imagine the Indians are too poor (and not despotic enough) to irresponsibly waste the money. In China, even if it is a waste, if the big men say do it, you do it.
My only thought is that the inherent dishonesty of Indian organizations will lead to the rockets not working and lots of fingerpointing and ass-covering. And no real accountability.

The second stage after delivering the payload in the orbit will be made to re-enter the atmosphere and will be recovered using airbags either in the sea or land, he said adding, "This is only in its conceptual stage."
Reminds of that recovery mission by the nasa (the one before this weekend) where it ended up halfway to china.
India rocket science. Oh yeah there is an image that doesn't have a tiny bit of a mismatch. Offcourse by now they probably turning out more rocket scientist then the rest of the world but I was raised by "It ain't half hot mum" and old prejudices die hard. BTW the idea of English rocket scientist is just as funny.
And what the hell is up with the figures quoted?
"we need to bring down the cost to access to space to 1/10th of the current per kg cost -- that is something like $500 to$1,000 per kg,"
Now matter how you put that it doesn't seem like the current costs can be that high. The end line:
The present cost of the space transportation system hovers somewhere between$12,000 to$15,000 per kg.
Doesn't make it much clearer but no matter how you look at it doesn't seem that expensive now does it? Sure sattelites can be more massive then you think and weigh easily in at a metric ton but 15million is hardly going to break the bank now is it?
So what the fuck is up with this? What are the real prices and what are the prices they hope for? I mean you could read it as as little as 500 dollars per kg. That is cheap.
Sounds like one of those advanced concept plans the NASA and ESA etc put out when it has been a slow month and there are no cute mars robots to keep the press intrested. Very nice but I seen such stuff promised since I was a kid and we are still stuck with the old rockets and space shuttle. GIVE ME MY MOONBASE!

Indeed. The Pegasus launch vehicle has been proving this for years. Being hauled to 40,000 ft by a carrier aircraft and having wings to provide lift in the lower atmosphere atmosphere dramatically shrink the size of the launch vehicle. Only program is the idea doesn't scale very well. Pegasus can only carry about 1000 lbs to LEO. There aren't any jets that can carry a much larger vehicle.
I am a little suprised at the naivete of the Mr. Nair's comments. The quote could have come from a NASA administrator back in 1969 when they proposed the Space Shuttle. The idea of reusable, winged launch vehicle has been pretty well discredited, both by the US with the shuttle and by the Russians with Buran.

They use a Java applet for every single link on the page. Please us before posting a link like that.
Why is it that when you believe something it's an opinion, but when I believe something it's a manifesto?
The only thing that will lower launch costs, other than the threat of loss of something like the cold war is incentives for private enterprise.
Seastead this.
I can see curry shrimp floating around now, with the astronauts in Nehru caps.
That sounds the same as other countries with much higher labor costs. What are they paying these ISRO employees? Enough for a house?
If it's a NASA article, the cost is mainly from retaining the permanent staff between launches. If it's an ISRO article, the only explanation besides Indians being independantly wealthy is the hardware costing 10 times more.
Bah, India always comes out with these hare-brained ideas that it never delivers on. There was that Avatar scram-craft, and all the other ideas that have sprung forth from ISRO, DRDO, etc. Talking the talk is a lot different than walking the walk.
The only thing I can see that might have prompted this announcement, is due to India's successful testing of a scramjet on the ground -- in a wind tunnel. The US had done that nearly a half-century ago.
One scramjet windtunnel test, and already people are conjuring up castles in the sky. Silly.
Thank you Kanye West of Asia. My whole family happens to come from the rural part - shacks, huts, and all. I'll tell you that the stifling oppression of socialism has kept far more people in poverty than has space program spending.
But hey, since charity begins at home, why not start with yourself, and ask your own president to send more bucks to urban ghettoes where the murder rate is higher than in any 3rd world country, rather than sending poor youth to die over in Baghdad.
I'm planning to have Catherine Zeta Jones as my wife. The project is in a conceptual stage right now, but I'm planning real hard. If only I could get some private funding to make myself fiscally attractive, I'd be all set.
They'll probably outsource the construction jobs to some overseas company. Oh wait...
Airbags work great on Mars (population 0, size 2/3 earth size), but would a 60 ton bouncing spacecraft work in India? (population ~1,000,000,000, size 1/50 earth)
First, quote what others in the US are doing or have done. Pretend you are inventing it, talk it up, then do nothing or do it with low quality and give up. Sorry India, but crashing spacecraft is worse than crashing software.
2-stage makes it sound like the craft from The Rocket Company. But the wings break that mold. And, if you ask me, are probably a bad idea! Why? Read The Rocket Company. (Just about the best near-term Sci-Fi book about building reusable rockets, but with *tons* of meaty science & engineering factual tidbits!)
European GPS system. European search engines. Indian space exploration. It's just like Civ IV. You've got the technological edge, then suddenly all your resources get diverted by a war, you're too busy being annoyed at the fact that your tanks are occasionally losing vs early gunpowder units, and the next thing you know all the other races have caught up. I'm hoping we get a great person in the next turn or two.
India has made great strides in Space. Now when I say it I am not being rhetorical. The space (satellites) program of India has helped bring cheap education to far flung, hard to reach areas. It gives upto the minute accurate weather reports and is one of the sources of weather forcasts of TV channels in India, India is aiming to jump into the select club of countries which have the capability of launching commercial sattelites over a specified weight thus bringing much needed foreign exchange. The sattelites give credible data which aids the scientists in the search for untapped (new) water bodies in the country. And these sattelites are the backbone for the mobile (telecommunication) revolution that is taking place in India at present.
So it is not just national pride that is making India take up space research seriously. It has put the technology to credible use which has brought a lot of comforts to the people living there.

Given my experience with support organizations that've been outsourced from the US to India (which, I'm sad to say, is pretty significant), I can't help but suspect that their first attempt (at least) will explode on the launch pad, probably claiming upwards of 3 dozen lives.
To be fair, tho', I'll say this to any member of the engineering team working on the deployment solution who may be reading: your launch vehicle won't require an Oracle CRM implementation, so don't buy it .
Heh. "...please type the word in this image: pred ict ..." Man, that's synchronicity.
But before going down that path, the folks in India should listen to this guy http://www.dunnspace.com/home.html#Columns. Getting into orbit is fundamentally different than flying an aircraft, and this Arthur Schnitt fellow argues that the max performance route used in aircraft is too costly. He got this idea of Minimum Cost Design from the Thor-Agena launcher for the Corona-Discoverer spy satellite -- the Thor booster was a lot cheaper than the Agena upper stage on top -- that cost had little to do with size in rockets, and by building big rockets with cheap methods (the Big Dumb Booster), you could reduce the cost of space launch

And don't forget about America's Space Prize a $50 million dollar prize for the development of a reusable vehicle to service http://www.bigelowaerospace.com/">Bigelow Aerospace's inflatable space hotel. (Robert Bigelow owns the "Budget Suites of America" hoetl chain). Several contendors for the prize at the moment.
And actually the american government is quite progressive on commercial space travel. They have an office: the office of Commercial Space Transportation. They actually recently put out a 120+ page proposal on regulations for human spaceflight, open for suggestions from the "players". Revisions are being suggested from companies and actually heeded. The system is working quite well.
Just from discussing it with customers of mine (who pay $150,000 for a week in Vegas for 2 people, what's $150,000 to hit space?), I bet there are at least 100,000 people in the world who would pay $50,000 to travel.
I've read studies that have similar numbers of people willing to pay bigger dollar amounts. The market is there; thats why the companies listed, among others, are working on a solution.
For anyone who has done more research than I could, what are the obstacles to private research? There's a market, there's a will, so there must be a way. Who is putting the kibosh on it?
Money. Gotta get those venture capitalists to see the vision. There are safer investments than human space travel. The companies that are most likely to succeed are the ones that are self-funded (see the ones with big names next to them) or the ones that handle both commercial and govenment contracts (for example, Xcor does government research, and spaceX does government launches. It pays the bills and bolsters investor confidence.)

I think Americans can spend their money a tad more wisely.
...they can consistently come up with enough stuff to trade for oil and raw materials. And that's a big "if". China is in the same position, except it has a lot more native raw materials to draw from, and a heckuva lead military wise, and hands down a huge lead in manufacturing capacity for stuff the rest of the planet is willing to trade dollars or other stuff for, like oil and raw materials. and they have been going any place on the planet that will have them and buying up natural resources and moving in "engineers and businessmen", half of whom are probably soldiers on the side if push comes to shove. Because today, they got the money, end of story.. India is on some pretty shaky ground long term right now, despite their advances. They've recently signed some energy cooperation treaties between the two nations, but I see them as similar to the pact signed between Germany and the USSR prior to hostilities starting. In diplomatic circles, the more large smiles and photo ops and hearty handshakes and pieces of fancy scrolled edges paper needed, the more actual true tension exists in the background.
This is shit that all the ignorant slashdotters need to know.
A survey several years ago identified the following statistic in the United States of America where it was found that:
38% of Doctors in America are Indians.
12% of Scientists in America are Indians.
36% of NASA employees are Indians.
34% of MICROSOFT employees are Indians
28% of IBM employees are Indians
17% of INTEL employees are Indians
A great majority ( over 85% ) of these people are foreign born, ie they are naturalized citizens of the US, and had a good deal of their early education abroad.
So when you are sceptical about the abilities of people of Indian origin, you are questioning the very same brains that built the operating system that runs most desktops, as well as helped put the rovers on Mars and drive our space program.
Retard.
Before jumping into space, I'd concentrate on the whole, you know, like... third world deal - poverty, starvation, destitution, banditism, diseases that doesn't exist elsewhere anymore, steam engines, mud huts...

The principle is: Take a plane which can gather height quite fuel-efficient and then launch a specially designed spacecraft from this plane.
Saves a lot of fuel, might proove safer (the accellerations needed are not so high) and allows a complete reuse of the whole system.
But great ideas (this idea (I think it's even completely caculated through) for more than 40 years.) alwas rot in favour of inferior ideas.

If this NASAThink has infected the ISRO I'm afraid the only cost reduction they will be capable of is because of somewhat lower labor costs.

The military requirements are a huge part of made the shuttle unworkable. But OTOH the military did not really want to launch via the shuttle.
The short history of the space program in the 1970s:
Apollo/Skylab winds down. The goal of beating the Soviets has been achieved. Congress is eager to cut the space program's budget (and so Apollo 18-20 are cancelled) but NASA has has big dreams.
NASA asks for money to build a space station and a dozen or so space shuttles to service it. Congress says, you can either have a space station or a shuttle program; not both. So of course NASA has to choose the shuttle.
In addition, Congress mandates that all US space launches will have to use the shuttle. The idea is that this will save money, since there will only be one type of launch vehicle to build and maintain.
So of course the military has a list of requirements: large cargo space, one-around capability, downrange landing capability, launch complex from which it can reach polar orbit (i.e., SLC-6 at Vandenberg).
And so we wind up with the shuttle we have today.
I sense you're trying to imply that my honest opinion on this "tech matter" is somehow off topic and inappropriate in this forum.
