Science Scene - What is Next for NASA?
However, the Constellation program – and the $9 billion already spent developing its Orion crew vehicle and Ares rockets – is decidedly dead.
In a press conference Sunday, Office of Management and Budget Director Peter Orszag told reporters the White House is recommending Constellation be scrapped, turning the run-of-the-mill duties of shuttling astronauts into low-earth orbit over to private companies and shifting NASA’s focus to “"advance robotics and other steps that will help to inspire Americans and not just return a man or a woman to the Moon but undertake the longer range research that could succeed in human spaceflight to Mars."
Those precursory missions to the moon, Mars and nearby asteroids might entail more tele-operated robots like the Spirit and Opportunity rovers on Mars, as well as a robotic lunar lander or asteroid mission that demonstrates an ability to utilize resources from remote outposts in space. These will be substantially cheaper than manned missions, generally less than $800 million each. But the thrilling prospect of a manned mission back to the lunar surface within the decade as envisioned in Constellation is more or less out of the question.
Highlights from the proposed NASA budget:
•$6 billion over five years to catalyze development of American commercial human spaceflight vehicles.
•$7.8 billion over five years for technology demonstration programs for future exploration activities. These might include technologies aimed at rendezvous and docking in orbit, refueling vessels in space, advanced life support systems for astronauts and other developments that will facilitate future missions beyond low-earth orbit.
•$3.1 billion over five years for aggressive research into heavy-lift rocket engines (but not the Ares-V), new propellants, and innovative ways of reaching deep space.
•$4.9 billion over five years for investment in early-stage and game-changing technologies incubating in the private sector. These could include innovations in sensor tech, robotics, launch vehicles, communications, etc., and will likely be funded through X-Prize-like performance-based grants that reward private sector space companies that can hit certain benchmarks quickly.
•$3 billion over five years to fund a string of cost-effective exploratory unmanned missions to the moon, near-earth asteroids and even Mars, scouting future manned exploratory targets.
