The rover will be outfitted with scientific instruments to look for signs of ancient life on the red planet. These include a state-of-the-art mass spectrometer and an organic molecule analyzer, which will come in handy as the vehicle collects samples at the Oxia Planum landing site. The mission has been stuck in development limbo since 2001, with delays caused by budget problems, technical issues, shifting international partners, and geopolitical fallout. After NASA dropped out, Russia stepped in, then was cut loose after invading Ukraine, and now -- despite NASA rejoining in 2024 and fresh political budget threats -- the rover is tentatively back on track for a 2028 launch.
