During the ordinary course of day to day life, we tend to think of planets as being unmoving and unchanging. There are few things more dependable than the ground beneath our feet, but that’s ...
This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts. The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay. Colour key:
Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released Monday are based on ...
On 2 December 1971, the Mars 3 lander became the first spacecraft to achieve a soft landing, but its transmission was interrupted after 14.5 seconds. [47] The Mars 2 and 3 orbiters sent back a relatively large volume of data covering the period from December 1971 to March 1972, although transmissions continued through to August.
