No one under 20 has lived a day without NASA at Mars
As the Mars Pathfinder spacecraft approached its destination on July 4, 1997, no NASA mission had successfully reached the Red Planet in more than 20 years. Even the mission team anxiously awaiting confirmation that the spacecraft survived its innovative, bouncy … Continue reading
Revisit Mars Pathfinder and Rover in 360°
You can explore the landing site of NASA’s Pathfinder mission with your mouse or mobile device. This 360-degree view uses images taken in 1997 displayed using present-day technology. It includes the lander’s companion rover, Sojourner – the first rover on … Continue reading
HiRISE: Plateau in Ares Vallis
This channelized area is near the source region of the huge outflow channel, Ares Vallis. It was at the distal end or “long-ways down-river-area” where the Pathfinder/Sojourner mission landed on 4 July 1997. This tiny region of Ares Vallis is … Continue reading
