Mars-2020 / Perseverance
No (non-launch cover) postal items found

1On 4 July 1997, the Pathfinder spacecraft entered the Martian atmosphere. Its aeroshell/heatshield slowed it sufficiently for a supersonic parachute to deploy and slow the package to 68 m/s. The lander then detached from the aeroshell and, at around 355 m above the surface, the airbags inflated (in less than a second). Three solid propellant retro-rockets fired at 100 m above the surface to further reduce the lander's descent rate and were then discarded, along with the parachute, at about 21.5 m altitude. The lander, stowed within the airbags, hit the surface at about 14 m/s, generating some 18 g's of deceleration. The package bounced at least 15 times before coming to rest, after which the airbags deflated and liberated the Sojourner rover.
2A Viking-3 Mars lander/rover was a proposed follow-on mission to Viking-1 and 2.
