On Mars, a NASA Rover and Helicopter’s Year of Surprise and Discovery
The New York Times
The past 12 months on Mars have been both “exciting” and “exhausting” for scientists and engineers minding Perseverance and Ingenuity. And the mission is only really getting started.
A year ago, NASA’s Perseverance rover was accelerating to a collision with Mars, nearing its destination after a 290-million-mile, seven-month journey from Earth.
On Feb. 18 last year, the spacecraft carrying the rover pierced the Martian atmosphere at 13,000 miles per hour. In just seven minutes — what NASA engineers call “seven minutes of terror” — it had to pull off a series of maneuvers to place Perseverance gently on the surface.
Given the minutes of delay for radio communications to crisscross the solar system, the people in mission control at NASA’s Jet Propulsion Laboratory in California were merely spectators that day. If anything had gone wrong, they would not have had any time to attempt a fix, and the $2.7 billion mission, to search for evidence that something once lived on the red planet, would have ended in a newly excavated crater.
