Right here’s the best way to watch NASA’s Perseverance lander contact down on Mars

All eyes are on Mars — and all ears, too. When NASA’s Perseverance rover touches down on the Pink Planet on February 18, the touchdown will likely be recorded with sight, sound and possibly even contact.

The rover will cap off a month of Mars arrivals from area businesses all over the world (SN: 7/30/20). Perseverance joins Hope, the primary interplanetary mission from the United Arab Emirates, which efficiently entered Mars orbit on February 9; and Tianwen-1, China’s first Mars mission, which arrived on February 10 and can deploy a rover to the Martian floor in Might.

NASA will broadcast Perseverance’s touchdown on YouTube beginning at 2:15 p.m. EST. The precise second of landing is anticipated at roughly 3:55 p.m. EST. Perseverance is designed to discover an historical river delta known as Jezero crater, looking for indicators of historical life and accumulating rocks for a future mission to return to Earth (SN: 7/28/20).

The rover will use the touchdown system pioneered by its predecessor, Curiosity, which has been exploring Mars since 2012 (SN: 8/6/12). However in a primary for Mars touchdowns, this rover will document its personal touchdown with devoted cameras and a microphone.

Because the craft carrying Perseverance zooms by the skinny Martian ambiance, three cameras will lookup on the parachute slowing it down from supersonic speeds. When a rocket-powered “sky crane” platform lowers the rover to the bottom, a fourth digicam on the platform will document the rover’s descent. One other digicam on the rover will look again up on the platform, and a sixth digicam will have a look at the bottom.

“The aim is to see the video and the motion of getting from excessive up within the ambiance right down to the floor,” says engineer David Gruel of NASA’s Jet Propulsion Laboratory in Pasadena, who was the engineering lead for that six-camera system, known as EDL-Cam. He hopes each engineer on the workforce has a picture of the rover hanging beneath the descent stage as their pc desktop background six months from now.

As a result of it’ll take greater than 11 minutes for indicators to journey between Earth and Mars, the cameras received’t stream the touchdown film in actual time. And after Perseverance lands, engineers will likely be centered on ensuring the rover is wholesome and capable of gather science information, so the touchdown movies received’t be among the many first information despatched again. Gruel expects to have the ability to share what the rover noticed 4 days after touchdown, on February 22.

Perseverance may also carry microphones to document first-ever audio of a Mars touchdown. In contrast to the touchdown cameras, the microphones will proceed to work after landing, hopefully serving to the engineering workforce maintain monitor of the rover’s well being. Motors sound totally different once they get clogged with mud, for example, Gruel says. The workforce will hear the sound of the rover’s wheels crunching throughout the Martian floor, and possibly the sound of the wind blowing.

“Are we going to listen to a mud satan? What would possibly a mud satan sound like? Might we hear rocks rolling down a hill?” Gruel asks. “You by no means know what we’d stumble onto.”

Sound will add a option to share Mars with individuals who have hassle seeing, Gruel notes. “It’d attraction to an entire different component of the inhabitants who won’t have been capable of expertise previous missions the identical manner,” he says.

Watch NASA’s dwell protection of the Perseverance touchdown right here beginning at 2:15 p.m. EST.Elsewhere on Mars, the InSight lander will likely be listening to the touchdown too (SN: 2/24/20). The lander’s seismometer could possibly really feel vibrations when two tungsten weights that Perseverance carried to Mars for stability smack into the bottom earlier than the rover lands, geophysicist Benjamin Fernando of the College of Oxford and colleagues report in a paper posted December Three to eartharxiv.org and submitted to JGR Planets.

“Nobody’s ever tried to do that earlier than,” Fernando says.

The bottom will transfer by at most 0.1 nanometers per second, Fernando and colleagues calculated. “It’s extremely small,” he says. “However the seismometer can be extremely delicate.”

The workforce could possibly catch that tiny sign as a result of they know precisely when and the place the affect will occur. If the lander does decide up the sign, it’ll inform scientists one thing about how briskly seismic waves journey by the bottom, a clue to the main points of Mars’ inside construction. And even when they don’t really feel something, that can put limits on the waves’ velocity. “It nonetheless teaches us one thing,” Fernando says.

The InSight workforce hopes to additionally really feel vibrations from Tianwen-1 when its rover touches down in Might. “Detecting one can be nice,” Fernando says. “Detecting two can be like, wonderful.”
