NASA efficiently landed its fifth robotic rover, Perseverance, on the floor of Mars on Thursday after its six-month voyage from Earth.
“Touchdown confirmed,” NASA’s Jet Propulsion Laboratory mission management mentioned at 3:55 p.m. ET. “Perseverance safely on the surface of Mars, ready to begin seeking the sands of past life.”
The rover is the most technologically superior robotic NASA has ever despatched to Mars. The company goals to spend practically two years utilizing it to discover the floor. NASA spent about $2.four billion to construct and launch the Perseverance mission, with another $300 million in prices anticipated for touchdown and working the rover on the Mars floor.
Based on its predecessor Curiosity, which reached Mars in August 2012 and remains to be in operation, the Perseverance rover was constructed by NASA’s JPL in California. Multiple corporations contributed to elements of the spacecraft, akin to the Lockheed Martin-built warmth defend, Aerojet Rocketdyne-built rocket thrusters and the Maxar Technologies-built robotic arm.
Perseverance can also be carrying a small helicopter named Ingenuity, which NASA plans to make use of to try the first flight on another planet.

The rover, about the dimension of a small automobile, weighs about 1 ton and is 10 toes lengthy by 9 toes broad by 7 toes tall. It has a robotic arm that reaches about 7 toes, the finish of which has a robotic “hand” that has a digital camera, a chemical analyzer and a rock drill. Perseverance is nuclear powered, with a plutonium generator offered by the U.S. Department of Energy to generate electrical energy for its pair of lithium-ion batteries.
Perseverance traveled 293 million miles to succeed in Mars over the course of greater than six months after it launched on a United Launch Alliance Atlas V rocket on July 30.

The rover’s touchdown featured the typical “seven minutes of terror” that NASA engineers describe in any spacecraft try to land on Mars. That’s the time it takes to enter the Martian ambiance and descend to the floor, and it is named as such as a result of it takes 11 minutes for any communication to journey from the rover again to Earth — which means the time delay requires that the spacecraft and rover carry out the touchdown autonomously.
Perseverance entered the Martian ambiance in a capsule that protected the rover because it traveled at about 12,100 miles per hour. The spacecraft then deployed a parachute to start slowing down earlier than jettisoning the capsule and warmth defend, after which firing its rocket thrusters to sluggish itself down from about 170 mph to about 2 mph.

The spacecraft subsequent deployed its “sky crane,” which lowered the rover the remaining few toes right down to the floor.

Perseverance landed in the Jezero Crater, a 28-mile-wide basin in the northern hemisphere of Mars. It’s a spot the place NASA believes a physique of water about the dimension of Lake Tahoe used to move. NASA’s science workforce hopes the historic river delta could have preserved natural molecules and different potential indicators of microbial life, which Perseverance will try to detect with its devices.

In addition to its scientific devices, the rover additionally carries a commemorative plate to honor Covid-19 health-care employees and acknowledge the affect of the pandemic.
The rover additionally has the names of 10.9 million folks stenciled into three silicon chips on the rover, with the phrases “Explore as one” written in Morse code.
The rover is filled with cameras to seize its expedition and chock stuffed with scientific devices to measure the planet’s geology and accumulate samples that NASA goals to someday return to Earth.
NASA plans to drive Perseverance round the floor for one Martian yr, which is equal to 687 days on Earth.
It has seven main devices for all kinds of functions: the Mastcam-Z; the Mars Environmental Dynamics Analyzer, or MEDA; the Mars Oxygen In-Situ Resource Utilization Experiment, or MOXIE; the Planetary Instrument for X-ray Lithochemistry, or PIXL; the Radar Imager for Mars’ Subsurface Experiment, or RIMFAX; the Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals, or SHERLOC, and the SuperCam.
The rover additionally has a pattern caching system, which has 9 totally different drill bits and lots of pattern assortment tubes to seize items of the Mars floor.
“Perseverance is the first rover to bring a sample caching system to Mars that will package promising samples for return to Earth by a future mission,” NASA mentioned in a press launch. “Rather than pulverizing rock the way Curiosity’s drill does, Perseverance’s drill will cut intact rock cores that are about the size of a piece of chalk and will place them in sample tubes that it will store until the rover reaches an appropriate drop-off location on Mars.”
NASA hopes to return the samples as a part of a marketing campaign in partnership with the European Space Agency a while in the future.
The rover is designed to cowl extra floor than another robotic despatched to Mars earlier than. NASA designed Perseverance to drive a median of 650 toes per Martian day, which is near the longest drive beforehand accomplished in a day at 702 toes by NASA’s Opportunity rover.

Perseverance can also be carrying the Ingenuity helicopter. NASA plans to deploy the helicopter from beneath Perseverance in a flat space a few months after the touchdown. The rover will then drive about 330 toes away, to seize the flight try with the rover’s cameras.

If all goes effectively, Ingenuity’s flight might be the first powered managed flight on another planet, in what NASA describes as “a Wright Brothers moment” on Mars.
