Sketch of a circumlunar free return trajectory (not to scale), plotted on the rotating reference frame rotating with the moon. (Moon's motion only shown for clarity) In orbital mechanics, a free-return trajectory is a trajectory of a spacecraft traveling away from a primary body (for example, the Earth) where gravity due to a secondary body (for example, the Moon) causes the spacecraft to ...
Maestro (software) was a free program released by NASA to allow users to view photos and daily progress of the Spirit and Opportunity rovers. It served as an activity planner for Mars that utilized a combination of 2D and 3D visuals to track the movement and missions of the Spirit and Opportunity rovers in 2004.
Millennium 2.2 is a resource management computer game by Ian Bird, released in 1989 for Atari ST, Amiga and MS-DOS. The MS-DOS version of the game was released as Millennium: Return to Earth. It is the forerunner to Bird's Deuteros, which is in a similar resource management game but many times larger and more difficult.
Tianwen-3 (Chinese: 天问三号) is a planned Mars sample-return mission by China which would send two spacecraft (an orbiter/Earth-returner and a lander/ascent-vehicle) via two separate launches to Mars. Together, the two spacecraft will seek to obtain samples of Martian rocks and soil and then return the cached samples to Earth. [1]
“Mars Sample Return will be one of the most complex missions NASA has ever undertaken. The bottom line is, an $11 billion budget is too expensive, and a 2040 return date is too far away ...
The Sample Collection for Investigation of Mars (SCIM) is a mission concept for a Mars air and dust sample return. It was a semi-finalist at the Mars Scout Program along with four other missions in December 2002. [2] [3] The SCIM mission would be designed to skim through the Mars atmosphere without landing or entering orbit. [1]
The move to redesign the mars sample return strategy comes after a NASA-commissioned independent review concluded last September that the program was hindered by "unrealistic budget and schedule ...
