It hasn't been the best of times for NASA in recent days. Not only is a presidential panel warning that the space agency will have to dramatically scale back its long-term ambitions if it wishes to stay on budget, but August has been plagued by malfunctions and delays across multiple projects and missions in progress.
A probe known as LCROSS, set to release a spent rocket booster to the moon's surface this fall in a hunt for water ice there, has suffered perhaps the most serious setback. This week, NASA announced that the spacecraft had unexpectedly squandered its fuel in an attempt to maintain its orientation after switching to an alternate attitude sensor.
"Our estimates now are if we pretty much baseline the mission, meaning just accomplish the things that we have to (do) to get the job done with full mission success, we're still in the black on propellant, but not by a lot," LCROSS project manager Daniel Andrews told Spaceflight Now.
Yesterday, NASA hit another snag at a demonstration and ground test of a next-generation rocket intended to be the launcher for the aging space shuttle's replacement. That rocket, known as Ares I (pictured at left), may never get off the ground—the same panel reviewing NASA's future plans is expected to present President Obama with at least a few scenarios that would scrap its development.
So when the rocket's handlers froze the Ares I test firing countdown at 20 seconds and then canceled the demonstration altogether, it was not an auspicious sign. A NASA official told Spaceflight Now that the problem was in a power unit that supports a thrust-direction system; the Ares test has been postponed until Tuesday at the earliest.
Space shuttle Discovery's next mission to the International Space Station, meanwhile, has yet to get off the ground after enduring two launch postponements this week, first due to bad weather at the launch site and then due to a faulty fuel valve in the shuttle's main engine system.
NASA plans for another attempt at blasting off to the station late tonight, and a safe, uneventful shuttle launch could be just the thing to cure NASA's summertime blues. Assuming clear skies in Florida (a 60 percent chance of good weather is forecast) and a clean bill of health for Discovery, the shuttle will lift off from Kennedy Space Center at 11:59 p.m. (Eastern Daylight Time).

Add CommentWow, Nasa is having some problems. I am torn between "is it the cheapest vendors fault" or is it good that NASA recognizes the good in being safe.
Reply | Report Abuse | Link to thisI read this blog as poor poor NASA can't get it right. I am tired of everyone harping on NASA and not addressing the problem of the oversight by congress and holding the carrot called funding over NASA's head.
As with ALL government agencies 50% of the time is covering your Arse and 25% trying to get funding in order to do something and the other 25% is attempting to get something done. Imagine if NASA could spend 75% to get the things done they needed to.
Nasa's heyday was the Apollo project, and it should have launched them to the stars, unfortunately they were handicapped by the shuttle, definitely a Government project, wrong specs, wrong idea, no real Initiative. But to give them credit, they made it work, however at a cost which will now forever hinder their progress. I think Nasa's future lies in supporting fledging ambitious companies itching to carry on the apollo dream.

India's first moon mission Chandrayaan poised for a 2 year term ended abruptly yesterday after the radio link between the satellite and the ground control was lost. Yet, there was a huge pile of knowledge gathered from this setback.

When Nasa wanted to build the shuttle they were told to do it with 10 billion even though they came up with a really useful, safe and easily reusable design for 15 billion. then once they came up with plans for something not quite as good or safe they were told their funding was suddenly cut to 5 billion per shuttle.
Reply | Report Abuse | Link to thisits a shame really. they should definitly start teaming up with private investors and pooling their resouces, maybe then we'll finally be able to at least explore our own solar system!
The shuttle is great machine, it's a pity they just couldn't operate it cheaper. I wonder if sometime in the future it will be built again (the right way). After all it's sort of neat to fly back home and park your space ship. Parachuting in is really test vehicle stuff.
