How to Watch NASA’s Perseverance Mars Rover Landing

On Thursday afternoon, Perseverance, NASA’s most bold self-driving rover, will try the company’s most difficult Mars touchdown. Perseverance is carrying a set of science experiments that can seek for indicators of life, launch a drone helicopter, and file the planet’s audio for the primary time. But conducting these experiments depends solely on whether or not “Percy” can stick the touchdown.

“I just want to say that landing on Mars is hard,” says Gregorio Villar, a techniques engineer with Entry, Descent and Landing group at NASA’s Jet Propulsion Laboratory. Historically, about half of the Mars landings tried by the US have failed, and Perseverance would be the largest rover to try it. The location complicates issues, too: The rover is aiming for Jezero Crater, a dry remnant of what scientists consider was a river delta 3.5 billion years in the past. “Typically, we try to go to kind-of-safe spots, like very flat areas that are not too scary,” says Villar. “But then that’s kind of boring for the scientists, right?”

Perseverance launched from Florida’s Cape Canaveral Air Force Station on July 30, however its journey actually started a couple of decade in the past. “There are literally thousands of people over 10 years who worked on this,” says Villar. The new expertise aboard the craft was designed to make difficult landings extra lifelike—and extra intriguing Mars missions potential.

This mission primarily facilities round trying to find historic traces of life. Once within the crater, Perseverance will use instruments just like the Planetary Instrument for X-ray Lithochemistry to look at soil textures for patterns indicating previous microbial exercise. The self-driving rover is provided with a first-ever microphone, plus 23 cameras, together with the SuperCam, a laser and digital camera setup that can analyze the chemical make-up of martian mud and minerals, probably revealing traces of long-ago life.

The rover additionally carries applied sciences unrelated to the seek for extraterrestrials. Ingenuity, a bit helicopter aboard Perseverance, will carry out the primary managed flight on one other planet—a Wright Brothers-esque second for JPL. And the experiments get energy from a battery that repeatedly recharges with US-made plutonium gas.

Since July, as Perseverance has been cruising towards Mars, the quite a few antennae aboard have been pinging high-frequency alerts to engineers again on Earth. One sign within the X band has relayed a type of “heartbeat” all through the rover’s journey. “Every certain amount of seconds, it’ll be like, ‘OK, I’m still good, I’m still good,’” says Villar.

Separate ultrahigh-frequency alerts within the megahertz vary may also transmit heavier information, like photos from Perseverance’s onboard cameras. The rover will talk with satellites orbiting the Red Planet, and people will transmit its alerts again to Earth. (NASA’s Mars Reconnaissance Orbiter, the Maven satellite tv for pc, and their NASA cousins have new firm: The United Arab Emirates’ Hope mission lately positioned a probe in orbit, which has despatched again its first photos.) These communication channels will proceed pinging NASA on touchdown day.

But even with all the cameras and the microphone, don’t anticipate an on the spot video feed. Those massive information will take some time to transmit. Even rudimentary communications just like the “heartbeat tone” take 11 minutes and 22 seconds to attain Earth presently of 12 months. That delay signifies that NASA engineers gained’t have real-time communication with the craft through the notorious “seven minutes of terror,” when it should survive its descent by way of the martian environment and land autonomously.
