H.R. 3057: To the Asteroids, Moon and Mars
apsmith writes "Democrats have just introduced the Space Exploration Act of 2003 to the U.S. House of Representatives; the author is Nick Lampson of Texas, with 26 co-sponsors. The bill sets a vision and goals for the future of NASA, beyond the Low Earth Orbit of the Space Station and Shuttle, outlining a series of incremental steps for human spaceflight. These include development of reusable spacecraft for carrying people around in the Earth-Moon vicinity, including to the nearby Lagrange points; sending people to an Earth-crossing asteroid; establishing a lunar base, and sending people to Mars with a base on a Martian moon by 2024."
Rep. Lampson's congressional district includes Johnson Space Center, which would benefit greatly from an expansion of manned spaceflight.
But then again, I could be wrong.
Rumors about their infamous program where true. Their advanced weapon programs contained powerful rockets capable of shuttling us to Mars and back.
Nope, not true. We've had rockets powerful enough to take us to Mars for years. We've just not had powerful enough rockets to take us, and all the oxygen we need to breathe while there, and burn to blast off and get back. If you run the numbers you'll see why, and then see that even super-duper-Iranian rockets aren't going to make up the difference.
The scientists are going to be able to make it to Mars though, and it's not because of a rocket break-through - it's because a few people were thinking outside of the box and figured out a better solution.

"Why bother sending people to an Earth-crossing asteroid?"
There is a high likelyhood that within the next 50 years we will detect an asteriod on it's way towards our planet for impact. Once detected, the only way to know how to best deal with it is to go TO it and determine exactly what type of asteroid it is. If it is a solid iron-nickle then we can actually bring the tools along with the survey crew to move it. If it turns out to be porous, there are other methods that can be used. The point is that we will need to determine this, and the most reliable piece of diagnostic equipment you can put in space is still a human. I would sleep a lot better at night knowing that we at least have the capability to intercept one of these beasts before it nukes us. This bit of exploration also becomes a part of survival. I love dual-use designs.

Here's the highlights:
... and additional studies to establish goals are not needed at this time.
... the main hurdle to be overcome is the lack of a national commitment to such activities.
"(7) There have been numerous commissions and study panels over the last 30 years
(8) While there are significant technical and programmatic hurdles
(11) While the ultimate goal of human space flight in the inner solar system is the exploration of the planet Mars, there are other important goals for exploration of the inner solar system that will advance our scientific understanding and allow the United States to develop and demonstrate capabilities that will be needed for the scientific exploration and eventual settlement of Mars."
w00t! I claim Tharsis Tholus!
"(20) Completion of the International Space Station with a full crew complement of 7 astronauts and robust research capabilities is essential if the United States is to carry out successfully a comprehensive initiative of scientific exploration of the solar system that involves human space flight."
Not so hot on this one.. again, Zubrin's proposals are passed over. Ah comprimise.
If you're not familiar with Zubrin, he made a plan 10 years ago to get to Mars with existing technology (Saturn VII), that would allow scientists months of surface time there, all for $10B:

"(4) Within 20 years after the date of enactment of this Act, the development and flight demonstration of a reusable space vehicle capable of carrying humans from low Earth orbit to and from Martian orbit, the development and deployment of a human-tended habitation and research facility on the surface of one of the moons of Mars, and the development and flight demonstration of a reusable space vehicle capable of carrying humans from Martian orbit to the surface of Mars and back."
Again, given Zubrin's work (that he presented to Congress), this is a bummer. We'll spend a lot of time building huge spaceships, instead of getting to Mars and settling it. A lot can happen in 20 years though.. perhaps any legislation like this is good. It's especially understandable given the recent shuttle disaster.. law-makers don't stick their necks out too far.
"(1) $50,000,000 for fiscal year 2004; and
(2) $200,000,000 for fiscal year 2005."
Now that's what I'm talkin' about.
According to this article there's lots of good stuff worth looking into:
(pasted from the link above)
The Lunar rocks may also be examined according to the chemicals that they contain. Such analysis indicates:
They are rich in refractory elements, which are elements such as calcium (Ca), Aluminum (Al), and Titanium (Ti) that form compounds having high melting points.
They are poor in the light elements such as hydrogen (H).
There is high abundance of elements like Silicon (Si) and Oxygen (O).
The high concentration of rare metals like Titanium, and the availability of abundant amounts of Silicon and Oxygen has led to serious proposals about mining and manufacturing operations in the future for the Moon.
but I can read Robert Zubrin's "The Case for Mars", a famous book that tells of the plan he prestend to Congress years ago. In it, he describes how to use Saturn VII rockets to launch a 2 phase, conjunction-class mission to Mars. The first phase carries no humans, instead carrying a machine to create rocket fuel, air and water out of the martian atmosphere. Once the return fuel is ready, you launch the second trip, with scientists. They get there after 9 months of artificial grav (tether-linked comparments set spinning) and set down to a full supply of oxygen and water, maybe even a backup supply.
They then do a many month investigation of the area surrounding the landing site, find life, invent martian versions geology, climatology, etc., and return home.
His estimated cost: somewhere around $10B, $20B and up for variations.
Repeat, repeat, repeat: settlement.
That was 10 years ago, and that's all off the top of my head.
You need the full GDP of the $US ($10T, or 1/5th of the money in the entire world) to do the same? I hope this isn't how the whole of JPL thinks, but if it is, perhaps that's why our space program is stagnant.
Now tell me what's wrong and ludicrous with his ideas (if you care to investigate them) and I'll find someone who can help you understand them.
If it turns out you're right, write a letter to these poor, misguided chumps in Congress.
Otherwise submit a proposal for their funding.
Or, get out of JPL and join me at McDonalds.
One of the things that you have to keep in mind is that NASA requires the use of military grade hardware. It has to undergo strict testing for a period of several years before it can be approved for mission-critical usage. You wouldn't want your CPU to glitch (Pentium 1, anyone?) and cause the spaceship to veer off course, would you?
This quote better sums up Kennedy's vision for space and technology:
We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.
