NASAs Perseverance Mars rover landing will be must-see TV – CNET


An illustration of Perseverance throughout its descent to the Martian floor.


NASA is simply weeks away from touchdown a shiny new robotic on the floor of Mars, and for the primary time, we’ll have the ability to see and listen to what it is like to the touch down on one other world.

Perseverance is because of land in Jezero Crater on Feb. 18, the primary synthetic object to land on the floor because the Mars Insight lander in 2018 and the primary rover since Curiosity touched down in 2012.

However the brand new rover on the block is carrying extra audio-visual gear than its predecessors to seize parts of the pivotal entry, descent and touchdown, or EDL, part of the mission. A digicam mounted on the again shell of the spacecraft is pointed up and can have the ability to catch a view of the parachutes that may deploy throughout descent to sluggish Perseverance because it is available in for its touchdown. Beneath this can be a downward-pointing digicam on the descent stage, which additional slows and orients the rover for touchdown. 

Lastly, the rover itself is supplied with cameras and a microphone. Altogether, this suite of tech ought to present us with probably the most detailed photographs and audio of a touchdown on Mars but.

“We’re going to have the ability to watch ourselves land for the primary time on one other planet,” Lori Glaze, who heads the Planetary Science Division of NASA’s Science Mission Directorate, informed reporters throughout a briefing Wednesday.


Perseverance carries its personal audio-visual rigging.


Your complete EDL part will final solely about seven minutes, however EDL lead Allen Chen calls it “probably the most vital and most harmful a part of the mission.”

Perseverance will hit the Martian ambiance touring at nearly 12,000 miles per hour  (19,312 kilometers per hour), streaking throughout the sky because it begins to decelerate. A 70-foot (21 meters) diameter parachute will deploy to sluggish it additional. Afterward, its warmth defend is launched and radar is activated to assist it decide its personal location. 

At an altitude of about one mile (1.5 kilometers), the descent module fires its engines and a brand new terrain relative navigation system, or TRN, kicks in to establish a secure touchdown spot. TRN is mainly a kind of laptop imaginative and prescient that enables the spacecraft to take a look at the terrain beneath and match it up with maps in its database.

The system slows right down to a literal crawl, after which it is time for “sky crane,” the identical kind of hovering touchdown system the Curiosity rover used, which is able to enable Perseverance to mainly decrease itself softly to the floor.

This complete course of can be totally automated with none enter from mission management due to the delay in sending radio indicators backwards and forwards from Mars to the Earth.

Perseverance carries numerous science devices to assist search for indicators of historic life on our neighboring world, to gather samples that can be returned to Earth and to check some applied sciences for future Mars missions.

Additionally, it has a tiny helicopter.

Robots have spent years rolling round Mars, which is fairly cool, however for the primary time NASA will use a small helicopter, dubbed Ingenuity, to attempt flying across the planet.

However earlier than Ingenuity can fly, Perseverance has to nail its touchdown first. Whereas its cameras and microphones will seize a lot of this complete course of, there will not be a dwell feed like we have turn into accustomed to from the Worldwide House Station or most launches from Earth. That is as a result of the info relay Perseverance can be utilizing throughout EDL is slower than even outdated dial-up connections.

Nonetheless, after touchdown will probably be ready to make use of the Mars Reconnaissance Orbiter to ship photographs again to Earth. Chen estimates that we’ll have the ability to see at the very least some low-res photographs of the surroundings round Perseverance on the floor shortly after touchdown. We might have to attend a couple of days for extra imagery and audio that paint the complete image of the touchdown course of.

We’ll, nevertheless, have dwell feeds from mission management, which supplied a few of the extra iconic photographs from the Curiosity touchdown. (Mohawk man, anybody?) In fact, COVID-19 protocols can be in impact at mission management, nevertheless it’s unlikely that even the pandemic will dampen the celebration of a profitable touchdown.

“I do not assume that Covid goes to have the ability to cease us from leaping up and down and fist bumping,” stated Deputy Mission Supervisor Matt Wallace. “You are going to see a lot of joyful individuals it doesn’t matter what, as soon as we get this factor on the floor safely.”
