description Overview

GRAIL

GRAIL, short for Gravity Recovery and Interior Laboratory, was a NASA mission that used two spacecraft to map variations in the Moon's gravitational field. Launched together in 2011, the probes flew in coordinated low lunar orbits and measured tiny changes in the distance between them. The resulting data helped scientists investigate the Moon's crust, interior structure, and geological history.

Viking 1

The Viking 1 mission involved both an orbiter and a lander deployed to Mars in 1975. It achieved the historic feat of delivering the initial extended scientific data from the Martian surface. The lander, Viking 1B, successfully touched down in Valles Marineris while the orbiter provided valuable reconnaissance. This mission’s findings significantly advanced our understanding of Mars and remain rel...
