Overview
NASA’s fifth Mars rover, Perseverance, successfully landed on the red planet last Thursday, February 18th and it will remain there for nearly two years searching for ancient life and exploring the surface. There have already been several newly released images by NASA and you can actually listen to a ~10 mph wind on the red planet (see below). Perseverance is the most technologically advanced robot NASA has sent so far having traveled 293 million miles to reach the planet over the course of more than six months. One of the highlights of the mission will be the deployment of a 19 inch tall helicopter named “Ingenuity” which will become the first rotorcraft ever used beyond Earth.
Details
The mission began in late July 2020 with an Atlas V rocket launch at Cape Canaveral Space Station in Florida. More than six months later, Perseverance landed successfully on Mars and will search for ancient life for nearly two years and explore the planet’s surface and collect dozens of samples. Perseverance’s landing involved the “seven minutes of terror,” a fiery atmospheric entry in a protective capsule that involved a parachute-assisted descent. The “seven minutes of terror” is referred to by NASA engineers as the time it takes to enter the Martian atmosphere and descend to the surface. The landing on Thursday, February 18th was inside a 28-mile wide crater known as Jezero – an ancient delta that scientists think could hold concrete evidence of past life on Mars. While Mars is fairly dry today, evidence collected by previous Martian missions suggests the Red Planet was once a warm, wet planet with conditions similar to those on Earth today. This leads scientists to believe that Mars may have once been a habitable world during its early history.
The SUV-sized Perseverance is designed to drive an average of 650 feet per Martian day and it features seven scientific instruments as well as a robotic arm that reaches about seven feet long and a rock drill. Perseverance is nuclear powered using a plutonium generator provided by the US Department of Energy. The spacecraft is guided solely by pre-programmed controls in its onboard computer, due to a roughly 11-minute signal delay between Earth and Mars. It will take some time to really get up and running for the rover as NASA will have many “infrastructure” tasks to complete in the next few months. In the near term, NASA will stabilize the robot’s power, thermal and communication systems so that it is ready to switch over to new software which is already on board. Other health checks are performed on instruments and the main battery will be charged. While it may take a few months to get operating at full speed, the main camera will begin taking color panoramas in just a few days.
Once Perseverance can get on the move, its first big trip will be to a Martian airfield and it’ll deploy a helicopter named Ingenuity which will become the first rotorcraft used beyond Earth. This little craft is only 19 inches tall and weighs just under 4 pounds. It has been tucked up in the belly of Perseverance since last summer. During Ingenuity’s first flight, the craft will lift up, flying about 10 feet above the ground and hover there for about 20 or 30 seconds. This will be an interesting test as Mars' atmosphere is less than one percent the density of Earth’s, so it may be too thin for the helicopter to successfully fly. If it succeeds, then space agencies can add aerial exploration of Mars to future missions. The hope is that the helicopter preparation and test flights will be successfully completed in the spring and science work can start in earnest this summer. Ingenuity is powered through solar panels that charge up its lithium-ion batteries for one 90-second flight per Martian day. This entire mission will help prepare NASA for future human exploration on Mars which is currently on the books for the 2030s.
Full NASA video of landing
NASA's Mars 2020 Perseverance mission captured thrilling footage of its rover landing in Mars' Jezero Crater on Feb. 18, 2021. The real footage in this video was captured by several cameras that are part of the rover's entry, descent, and landing suite. The views include a camera looking down from the spacecraft's descent stage (a kind of rocket-powered jet pack that helps fly the rover to its landing site), a camera on the rover looking up at the descent stage, a camera on the top of the aeroshell (a capsule protecting the rover) looking up at that parachute, and a camera on the bottom of the rover looking down at the Martian surface.

Audio from Mars:
This set of sounds from the surface of Mars were recorded by the microphone on the side of NASA’s Perseverance Rover on Feb. 20, 2021. In the first set, sounds from the rover itself dominate. In the second set, the sound was filtered to make sounds from Mars more audible. You can hear a little wind in the second set (estimated to be around 10 mph). This is the first time a Mars rover has been equipped with a microphone. (Recommend headphones)
