NASA has released the final request for proposals for a Mars telecommunications system, confirming requirements that limit the companies that can bid on it.

NASA’s Perseverance rover is living up to its name as its total distance traveled approaches the length of a marathon. Over the past five years, this intrepid explorer has traversed more than 26.05 miles (41.

NASA's Perseverance rover took its sixth ever selfie from the red planet during a recent excursion west of Mars' Jezero Crater. And, researchers studying the pollution from satellite megaconstellations found the soot from these launches may have some concerning climate effects.

On Thursday, NASA issued a Request for Proposal (RFP), seeking industry collaboration for the Mars Telecommunications Network.

As scientists search for life beyond Earth, spacecraft need to avoid accidentally bringing organisms from our home planet to other celestial bodies. It would be unfortunate to discover that an “alien” life form was simply a hitchhiker.

We took this image when the rover was in the ‘Wild West’ beyond the Jezero Crater rim—the farthest west we have been since we landed at Jezero a little over five years ago,” Perseverance project scientist Katie Stack Morgan said in a statement.

Nasa is developing ways to use nuclear power to send spacecraft to their destinations. Nuclear propulsion could greatly reduce the journey time to Mars, perhaps cutting a voyage of more than six months to three or four months.

Engineers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, have demonstrated that the blades of their next-generation Mars helicopter rotors can punch past the speed of sound and come out intact.
