Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months and they can advance the knowledge of how to perform very remote robotic vehicle control.
What is the flyby spacecraft?
As part of Deep Impact’s Flight System, the flyby spacecraft is one of two vessels carrying the three science Instruments. Ball Aerospace & Technologies Corp. designed the spacecraft specifically for the Deep Impact mission.
What happens during the encounter phase of a flyby mission?
During the encounter phase, a high gain antenna transmits near-real-time images of the impact back to Earth. The flyby spacecraft uses X-band to communicate to Earth and S-band to communicate with the impactor after separation. Debris shielding is a key part of the flyby S/C design.
