Tomorrow the Mars Rover “Perseverance” will land on the Red Planet at 3:55 p.m. Eastern U.S. time (2:55 Chicago time, 8:55 pm London time). You’ll want to be awake then, for the landing will be filmed live with several cameras! NASA has a countdown page here, which links to all kinds of information about the Rover and the mission. Tomorrow afternoon I’ll post some links where you can watch the landing, assuming that all goes well.
The landing sequence of this gizmo in Jezero Crater is known as “The Seven Minutes of Terror” because the slowing down of the spacecraft from 12,100 miles per hour to just 1.7 mpg right before landing takes seven minutes and a ton of complicated technology. All of that was recently programmed into the spacecraft and rover: since there’s an 11-minute delay between Earth and Mars communication, we won’t know whether the Rover has landed until it’s all over. And there’s nothing anybody can do to help at Mission Control.
Here’s a NASA animation showing how damn complicated this landing will be! It involves separation of the module containing the rover, deployment of a parachute, jettisoning of a heat shield, jets helping navigate over the surface to find a good landing spot, and most amazing, a “sky crane” that gently lowers the rover to the planet’s surface and then flies away.
It’s stunning that a mammalian species can pull off something like this. Don’t miss the live feed tomorrow!
This is a SCIENCE mission, and the rover will be landing in a crater that harbors an ancient delta. As Space.com reports,
Perseverance, or “Percy” for short, will explore the Martian terrain and conduct a number of science investigations. Among its objectives, Percy will collect samples, deploy the first helicopter beyond Earth, and search for signs of ancient life on the fourth planet from the sun.

I guess there will be sound, too, as there is an array of cameras and a microphone:
