NASA is pitching a cheaper and quicker way of getting rocks and soil back from Mars. Administrator Bill Nelson presented two options on Tuesday, less than two weeks before stepping down as NASA's chief.

Previously, the Mars Sample Return mission had been estimated to cost around 11 billion dollars and would not return a sample until the 2040's, noted Nelson, who said a re-evaluation of the mission had to be done because "this thing had gotten out of control."

We may be about to discover the fate of the Mars samples collected by NASA's Perseverance rover. On Tuesday, January 7 at 1:00 pm EST, NASA administrator Bill Nelson and associate administrator Nicky Fox are going to provide an update to the mission left in limbo.
