No sure if we have a miss print here or is this space exploration on the cheap?
News just in says NASA gave SpaceX $75 million for a trip to MARS!
http://www.news.com.au/technology/sc...-1226044123413
Now if they had given them $75 billion the story might be believable but for $75 million you don't even get off the ground
Think of it as a grant. Did you read the article?
"SpaceX is one of the two leading private space companies in the US and has won $75 million from the US space agency NASA to help its pursuit of developing a spacecraft to replace the space shuttle."
A real drop in the bucket for what has been explained as an ambitious goal but don't worry they might be able to buy a used shuttle
The money is for research. Its not to actually build anything yet. They are still in the testing phase.Quote:

We know how. That part is easy. The real questions is "how best". That requires research. Also to fine tune what already exists.Quote:

We went to the Moon and didn't discover a good reason to establish a research base there.
Travel to Mars obviously requires much larger vessels to serve the needs of a human crew and there seems little point to going there other than some alturistic idea that because it is there we must go. We know how to build bigger vessels, we don't know how to get them off the Earth and you won't get a prototype for $75 million.
Surely right now there is better use for that money in fostering research in solving a few problems closer to home, unless of course, this is veiled military research
I tend to agree that at this time humans have not conquered the long term challenges of weighlessness for an extended period.Quote:

A large voyager to Mars would be assembled in pieces in low Earth orbit... probably docked at ISS or a similar platform. It would waste too much fuel to launch from the ground.
Once water was discovered at the polls of the moon then a colony or military base became conceivable. For that reason alone a US mission should be attempted . Our world competitors certainly consider the expense of owning the high ground worth the cost.
I don't know if the money is sufficient . I tend to be happy that NASA is privatizing much of it's mission(whatever that is... I don't believe they have a clear vision of what their mission is;and no clear directive from POTUS except to reach out to the Muslims ) .
By the way ; the $75 million is not for a Mars mission . It is for an escape system for the SpaceX Dragon spacecraft . The Dragon may some day be an answer to transport US astronauts into low Earth orbit... effectively replacing the Shuttle as a human transport vehicle .
As it is a private enterprise ,the Dragon can also be used for other commercial ventures in space.
The Falcon9 lifter is seen as a cheaper replacement for the Ares V rocket that NASA had approved last decade .
Just more money vanishing into a black hole
If you were going up in the capsule you might think an escape device important.
Tom I can't remember anyone previously thinking an escape device in a capsule is important, reentry capsules already exist and have been extensively tested. On a trip to Mars where are you going to escape to? Any devise you could get back to Earth in would need to be almost as sophisticated as the transport vehicle. Propulsion systems, navigation systems, long term air supply, food, etc. What we are really saying is we haven't made any significant advances in our thinking in forty years, so the $75 million might just be buying some new brain power
As I already pointed out the Dragon is not a vehicle capable of a Mars mission. It is a commercial replacement for the Shuttle
SpaceX Wins $75 Million NASA ContractQuote:
WASHINGTON D.C. (April 19, 2011)--Space Exploration Technologies (SpaceX) has been awarded a $75 million from NASA to develop a revolutionary launch escape system that will enable the company’s Dragon spacecraft to carry astronauts.
It will not have the dual capability of carrying cargo and passengers .But will give us the alternative to carry our own passengers instead of relying on the Russians.
Seems to me you already have a proven vehicle called a shuttle but someone forgot to develop its capability why do you need a commercial replacement? It isn't as though there is a resort up there, just keep flying schuttle after all you even have one that actually hasn't been used/Quote:

It takes too much fuel for low earth human launches ;and the life support is unnecessary to lift cargo.
But you said you wanted to take cargo and passengers. So what is wrong with some 1970's rockets like Atlas and some capcules? After all it works well for the Russians. Why don't you just admit someone loused up the planning, one of those brilliant Presidents you keep electing over there who have no vision beyond the next electionQuote:

What's the difference which private firm NASA contracts for the flights ?
The mistake was in building ISS . We shoud've instead established moon bases. We've wasted way too much time in low Earth orbit.
No votes in it Tom. You beat the Russians to the Moon and then run out of steam. Now you will have to beat the Chinese to Mars. I was reading up on SpaceX. They could lift a shell the size of an A380 up there and outfit it. No vision
The Chinese announced they will be building their own space station. So much for the idea of "international" cooperation in space.
And the Ruskies are trying to monopolize access to ISS .
Pajamas Media NASA Over a Russian Barrel
I agree with one of the comments in above link.The US should remove our sections of ISS and use one more mission of the Shuttle to tow it to a new location and attach it to a Bigelow .
