NASA is preparing to release the latest Announcement of Opportunity for its Discovery program, which will ease restrictions on proposals that have contributed to cost and schedule overruns on previous missions, according to Andrew Dantzler, director of the Solar System Division at NASA headquarters.
NASA is keeping close watch on asteroid 2004 MN4, which Apollo 9 Astronaut Rusty Schweickart thinks has a remote chance of hitting the Earth in 2036, but agency officials don't feel at this point that placing a transponder on the asteroid for better tracking would be worth the expense.
NASA's Deep Impact team remains confident as the spacecraft nears its July 4 high-speed rendezvous with comet Tempel 1, despite a focus problem that is hampering the capability of its high-resolution camera. When it nears Tempel 1, the Deep Impact spacecraft will release an 820-pound guided penetrator on a collision course with it. The mothership spacecraft has three sensors to observe the effects of the collision: the High Resolution Instrument (HRI), a Medium Resolution Instrument (MRI) and a duplicate camera on the Impactor Targeting Sensor (ITS).
