(CNN)The Perseverance rover may be parked at an overlook to capture any flights by the Ingenuity helicopter over the next two weeks, but it's not wasting any of its time on Mars.
The rover on Tuesday successfully converted some of the plentiful carbon dioxide on Mars into oxygen as a first test of its MOXIE instrument. The name MOXIE is short for Mars Oxygen In-Situ Resource Utilization Experiment.
After warming up for about two hours, MOXIE produced 5.4 grams of oxygen. This is enough to sustain an astronaut for about 10 minutes.
