| The new millennium begins with the launch of a new orbiter and a lander, ideally with a rover payload. |
| The new space vehicle will use a capsule similar to Apollo's and lander capable of carrying four astronauts to the moon's surface. |
| Rosetta is the first probe ever designed to enter orbit around a comet's nucleus and release a lander onto its surface. |
| The lander will return close-up pictures of the comet's nucleus, drill into the dark organic crust, and sample the primordial ices and gases. |
| A future mission should treat a Mars lander as an integral part of the whole spacecraft rather than one of its instruments, the report said. |
| Atop the external tank would sit a rocket stage and a 40-ton automated cargo lander covered by a streamlined shroud. |
