‘s Perseverance rover is scheduled to land on the Pink Planet on Feb. 18, the place it’ll search for indicators of microbes (lifeless or alive) and possibly even liveable environments.

Perseverance launched by way of an Altas V rocket on July 30, 2020, from Cape Canaveral, Florida. However its journey is simply starting. Thursday’s touchdown is one a part of an virtually $3 billion mission that can go on for one more 687 days—or one Martian yr (aka, one journey across the solar).

Perseverance appears to be like loads just like the older, nonetheless lively Curiosity Rover, which landed in 2012. It has about 85% of the identical {hardware}, Space.com says, which saved some huge cash and diminished threat, since NASA is aware of it already works. However Perseverance’s targets transcend taking photos.


What’s on Board?

Perseverance is on a mission—seek for indicators of historic life and accumulate samples that might be returned to Earth for examine. To hold this out, it’ll land on Mars outfitted with seven instruments value $130 million—selected by NASA in 2014 from 58 proposals. Here is what Perseverance is packing.

Mars Oxygen In-Situ Useful resource Utilization Experiment (MOXIE)

Perseverance is carrying know-how referred to as the Mars Oxygen In-Situ Useful resource Utilization Experiment (MOXIE), which can generate O2 out of Mars’ CO2 ambiance—the form of experiment which will assist people survive there sometime.

The 37.7-pound gadget “breathes like a tree,” NASA explains, inhaling carbon dioxide and exhaling oxygen. Provided that oxygen makes up solely 0.13% of the gasoline in Mars’ ambiance, in comparison with 21% in Earth’s ambiance, producing oxygen from the Martian ambiance might be essential for human survival on the Pink Planet.

MOXIE may also be used to create propellant, so individuals can discover Mars, and go away it to return to Earth. “Once we ship people to Mars, we are going to need them to return safely, and to do this they want a rocket to elevate off the planet. Liquid oxygen propellant is one thing we might make there and never should convey with us. One thought could be to convey an empty oxygen tank and fill it up on Mars,” says MIT’s Michael Hecht, Principal Investigator for MOXIE.

The Radar Imager for Mars’ Subsurface Experiment (RIMFAX) can peek beneath the planet’s ice, sand, and rock utilizing ground-penetrating radar with a variety of greater than 30 ft. It is just like radar used on Earth to probe the underground layers of rock and ice within the Arctic and Antarctic, NASA says. However it’ll be the primary radar instrument NASA sends to the floor of Mars.

“Nobody is aware of what lies beneath the floor of Mars. Now, we’ll lastly be capable to see what’s there,” says Svein-Erik Hamran from the College of Oslo, RIMFAX’s Principal Investigator.

Planetary Instrument for X-ray Lithochemistry (PIXL)

The Planetary Instrument for X-ray Lithochemistry (PIXL) sports activities an X-ray spectrometer that may dig round within the Martian rock and soil to take close-up pictures and measure the chemical make-up of supplies as small as a grain of salt. The concept is to search out indicators of previous microbial life on Mars, and small motors give this 10-pound gadget the flexibleness it wants.

“If you’re searching for indicators of historic life, you wish to have a look at a small scale and get detailed details about chemical parts current,” says NASA JPL Analysis Scientist Abigail Allwood, PIXL’s Principal Investigator.

A separate instrument, the SuperCam, may even be used to “establish the chemical composition of rocks and soils, together with their atomic and molecular make-up.” Its laser “is uniquely able to remotely clearing away floor mud, giving all of its devices a transparent view of the targets,” says Roger Wiens of Los Alamos Nationwide Laboratory, SuperCam’s Principal Investigator.

Remember the Scanning Liveable Environments with Raman & Luminescence for Organics & Chemical compounds (SHERLOC), which might be on the hunt for indicators of water and previous microbial life by way of its ultraviolet laser gentle.

Mastcam-Z

Mastcam-Z will principally operate as Mars’ in-house photographer, taking high-definition video, panoramic shade and 3D photos of the planet’s floor and ambiance with a reasonably fancy zoom operate. It is fairly compact; see the pocket knife within the picture above for scale. However its zoom “can see options as small as a home fly—all the best way from a distance that is concerning the size of a soccer area,” NASA says. Perched atop the rover, scientists again on Earth can use Mastcam-Z for a 360-degree view and to zoom in on rocks. “It tells us which rocks to core, cache, and possibly return to Earth sometime,” in keeping with NASA.

Mars Environmental Dynamics Analyzer (MEDA)

How’s the climate up there? That is a query for the Mars Environmental Dynamics Analyzer (MEDA), which can measure climate and monitor mud by way of sensors mounted on Perseverance. It will additionally measure radiation, which “can alter traces of any previous life in Mars rocks,” NASA says. “MEDA helps scientists perceive these adjustments and tells them what to search for.”


Mars Helicopter

Perseverance even has a drone; a small helicopter named Ingenuity will fly off on scout missions to see how powered flight works within the skinny Martian air. As NASA explains, the helicopter is form of a facet mission. It isn’t formally a part of the Mars 2020/Perseverance mission. However “its efficiency throughout these experimental check flights will assist inform choices referring to contemplating small helicopters for future Mars missions, the place they might carry out in a assist position as robotic scouts, surveying terrain from above or as full standalone science craft carrying instrument payloads.”


7 Minutes of Terror

After years of planning and months of journey, it is the complex landing that issues most. With the assistance of a supersonic parachute, what’s referred to as a “skycrane maneuver,” and different high-stakes strikes, the two,314-pound Perseverance makes its option to the floor of Mars this week. Solely 40% of Mars landings have been profitable up to now, in order that drop from Mars’s higher ambiance to the bottom has been dubbed “seven minutes of terror.”

The entire thing might be captured by Perseverance cameras, one pointing up on the parachute and skycrane, one other pointing down on the floor to document first floor contact—the primary time that is ever occurred.

So how do you watch this factor land—or crash—in Mars’s 28-mile extensive Jezero Crater? (NASA picked that spot north of the equator as a result of it was a lake, and might be a superb place for locating microorganisms and distinctive rocks, even when that lake existed 3.5 billion years in the past.)

Find out how to Watch the Perseverance Mars Rover Touchdown

The reply is, to look at it “dwell,”—conserving in thoughts the lag time for a sign from Mars to Earth (over 300 million miles) is up to 20 minutes. Be prepared earlier than 3:55 p.m. EST on Thursday, February 18. Protection begins at 2:15 p.m. EST in a number of locations:
