Why NASA's Budget Can't be Reduced

When 10,000 jobs are at stake, lawmakers start to listen. As reported in this article in Parabolic Arc, the big 5 space primes in America have ganged together to point out that NASA needs to accelerate its development of the next generation of space exploration vehicles, otherwise a lot of skilled labor will be forced to find work in other industries.

It is nice to see the specific reference to the Altair lunar lander in the plans that industry wants to start working on. Interestingly however, they don't refer to the Ares-1 launch vehicle which has recently suffered a 6 month delay.

Converting a "Moon-Impactor" to a "Moon-Lander"

As India's Chandryaan-1 mission showed this week, it's possible to use existing launch vehicles and conventional satellite design solutions to reach lunar orbit, and even to send a probe to the impact surface. The only remaining step in order to have a complete lunar surface transportation service is to master the technology of slowing down your lander to have a soft-landing, rather than the hard-landing (aka "impact") of the Indian probe.

In the 1960's, with its Surveyor program, NASA mastered the technology of using a solid rocket motor to decelarate a lander, removing over 90% of its speed to allow a relatively small liquid-fuel propulsion system to make the final descent and landing.

India Next to Land on Moon?

According to MoonDaily's AFP report India has announced that it will send a spacecraft to soft land on the Moon's surface by 2012.

India's Chandrayaan-1 mission currently orbiting the Moon is clearly providing them with some confidence that they can now proceed to the next level, a robotic lunar soft-landing. The proposed lander mission, Chandrayaan-2, would include a robotic probe able to "pick samples" for scientific study and transmit the science data back to Earth.

This announcement with a timeline compatible with the Google Lunar X PRIZE (GLXP) certainly lays down the gauntlet for the other major space agencies in the world that have not yet landed anything on the Moon but who claim to be preparing such missions, namely ESA, JAXA and CNSA. How will they respond?

Goverment Support for Future Lunar Missions

The recent post on the Space Prizes Blog makes an interesting point. Space agencies will probably need to show interest in using the lunar lander systems developed by GLXP teams otherwise investors will just not believe it is worth the effort developing lunar landers for a single mission.
