As @NASAPersevere collects rock samples for #MarsSampleReturn, engineers are testing designs for the Sample Retrieval Lander. Planting different footpads on a Mars-like surface helps find the right size – key for giving the return rocket a sturdy platform to launch from. 🚀

Were there multiple points in history where microscopic life could have been at Mars’ Jezero Crater? @NASAPersevere is carrying a core sample from a rock that may record a story of the ancient lake’s watery past. #MarsSampleReturn could bring samples to Earth for closer study.

What’s so special about the samples @NASAPersevere is collecting on Mars? Mission scientists are excited about samples 14 and 15, which came from a sedimentary rock. A similar rock on Earth could easily have signs of ancient life in it. Could that be true on Mars?
