The ISPP plant would manufacture liquid oxygen from carbon dioxide in the martianatmosphere.
2
Planetary astronomers had found no evidence of oxygen in the martianatmosphere, Tombaugh reported.

The lander would need deorbit propulsion so that it could slow and drop into the martianatmosphere.
4
A key investigation for the Trace Gas Orbiter is to search for the origin of methane in the martianatmosphere.
5
Reports of plumes or patches of methane in the martianatmosphere that vary over monthly time scales have defied explanation to date.

The Voyager landing capsule would enter Mars'satmosphere moving at between two and three miles per second.
4
Huge cloud-like plumes that were spotted by amateur astronomers stretching hundreds of kilometres into Mars'satmosphere have defied explanation - until now.
5
The lander might separate from the orbiter as it approached the planet and enter Mars'satmosphere directly with no stop in Mars orbit.
