How NASA’s Perseverance rover will land on Mars

NASA’s Mars rover Perseverance will make its descent onto the crimson planet on Thursday, however there are a couple of hurdles to cross earlier than it might probably land. 

The 2,260-pound rover — partly named in recognition of well being care heroes amidst the COVID-19 pandemic — launched late final summer time from Florida’s Cape Canaveral Air Drive Station and has since traveled 293 million miles to succeed in its vacation spot.


Its goal is Jezero Crater, a carefully-selected location for Perseverance’s mission in astrobiology. NASA’s fifth Mars rover is tasked with trying to find indicators that microbial life could have lived on the planet billions of years in the past, in addition to accumulating rock and soil samples that can ultimately be returned to Earth.

Engineers managing the mission on the NASA Jet Propulsion Laboratory in Southern California wrote in a Tuesday information launch that the rover was on monitor to the touch down at Mars’ Jezero Crater at roughly 3:55 p.m. ET.

However, touchdown is a traditionally dangerous transfer, with round a 50% success charge

With that in thoughts, Perseverance was constructed with new {hardware} and superior expertise to see it safely deployed from its entry capsule. 

It is a multi-step course of and engineers will obtain alerts concerning key milestones on an 11-minute-and-22-second delay.

First, the spacecraft that has been flying Perseverance and NASA’s Ingenuity Mars Helicopter will separate at round 3:38 p.m. ET after which enter the planet’s environment at 3:48 p.m. ET.

What’s following is called the “seven minutes of terror,” throughout which the environment will warmth the underside of the spacecraft to temperatures reaching as much as 2,370 levels Fahrenheit.

At round 3:52 p.m., the parachute will deploy at supersonic velocity and the deployment relies on new Vary Set off expertise that reduces touchdown ellipse and deploys primarily based on the proximity from its desired goal.

About 20 seconds later, the warmth defend will detach from the entry capsule, permitting Perseverance to make use of its radar to measure the gap from the bottom and its Terrain-Relative Navigation.

The perform makes use of pictures of the touchdown website to assist the rover precisely decide the place it is headed and the most secure level to succeed in — even on terrain beforehand inaccessible to engineers.

Subsequent, the again shell of the capsule that’s fixed to the parachute will separate from the rover and its “jetpack” at 3:54 p.m. and the jetpack will use retrorockets to assist Perseverance decelerate and attain its touchdown website.

Utilizing what is called the sky crane maneuver, the rover and Ingenuity will decrease all the way down to the floor on nylon tethers.

As soon as efficiently on the bottom, Perseverance will {photograph} Mars for engineers through a brand new relay functionality added to NASA’s Mars Reconnaissance Orbiter.

The mission carries extra cameras than any interplanetary mission in historical past, with 19 on the rover and 4 on different components of the spacecraft.

So as to perform its task, Perseverance is carrying seven devices to make the most of in unprecedented experiments and check new expertise.

The Mastcam-Z and Supercam are used to supply each imaging and evaluation of the floor’s mineralogy and chemical composition.

The Planetary Instrument for X-ray Lithochemistry — or PIXL — serves as a fluorescence spectrometer and high-resolution imager to detect and map fine-scale elemental composition of the Martian floor.

The Scanning Liveable Environments with Raman & Luminescence for Organics and Chemical substances (SHERLOC) spectrometer makes use of an ultraviolet laser to map mineralogy and natural compounds.

The Mars Oxygen In-Situ Useful resource Utilization Experiment (MOXIE) will try to supply oxygen from Mars atmospheric carbon dioxide.

The Mars Environmental Dynamics Analyzer (MEDA) is a set of sensors that can present “measurements of temperature, wind velocity and course, strain, relative humidity, and mud dimension and form.”

Lastly, the Radar Imager for Mars’ Subsurface Experiment (RIMFAX) is a radar that gives a centimeter-scale decision of the geologic construction of the subsurface.


Perseverance may even check new tech for future Mars missions, together with a brand new set of sensors known as Mars Entry, Descent and Touchdown Instrumentation 2, or MEDLI2. 

To observe the occasion and hearken to commentary from specialists, viewers can tune in to NASA TV at 2:15 p.m. ET.
