It comprises a large orbiter, which is designed to operate for a decade at large distances from the Sun, and a small lander. |
The new millennium begins with the launch of a new orbiter and a lander, ideally with a rover payload. |
In other instances, an orbiter or a spacecraft on a flyby mission may have already taken photographs of a moon or planet. |
The plan will also position the Cassini orbiter farther away during that descent. |
But, once again, the orbiter failed to pick up a signal from the lander, ESA officials announced. |
An orbiter allows for a longer, more complete look at a planet but requires an engine and fuel to slow the spacecraft and insert it into orbit. |
