Questions & Answers

Q: What is MOXIE and why is it significant for future Mars missions?

MOXIE is an instrument on the spacecraft that converts Mars atmosphere into oxygen. This oxygen can be used as fuel for a future return flight from Mars or as breathable air for manned missions.

Q: What are the biggest challenges in building a spacecraft for Mars exploration?

One challenge is simulating the extreme temperature gradient on Mars during testing. Hardware and components must withstand a wide range of temperatures. Additionally, the wind and atmosphere conditions on Mars need to be considered when designing the spacecraft.

Q: What is the purpose of the Ingenuity helicopter on the spacecraft?

The Ingenuity helicopter is a proof of concept to test new technology on Mars. It will provide aerial shots and assist in exploring the terrain ahead of the Perseverance rover. It is stored at the bottom of the rover and can be deployed to take flight.

Q: How are samples collected on Mars?

The Perseverance rover has a robotic arm with a drill and various drill bits. It selects the appropriate bit based on the type of dirt or rock to collect samples. These samples, known as core samples, are preserved in sealed tubes for future retrieval.
