NASA and ULA are now targeting Monday, July 20, for launch of the Mars 2020 mission of the Perseverance Rover on an Atlas V rocket from Space Launch Complex-41 on Cape Canaveral Air Force Station in Florida.
Additional time was needed for the team to repair an issue with the ground system equipment. Launch is scheduled for 9:15 a.m. ET with a two-hour window.
Tests to measure the center of gravity and moments of inertia for the Mars 2020 rover aeroshell were performed on the spin table inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida.
The rover is being manufactured at NASA’s Jet Propulsion Laboratory in California and, once complete, will be delivered to Kennedy in mid-February. The rover’s heat shield and back shell arrived at Kennedy last month.
Two vital pieces of equipment for the Mars 2020 rover were flown from Lockheed Martin Space in Denver, Colorado, and recently delivered to the agency’s Kennedy Space Center.
The rover’s heat shield and back shell arrived at Kennedy’s Launch and Landing Facility (formerly the Shuttle Landing Facility) on Dec. 11, 2019, and were then transported to the Florida spaceport’s Payload Hazardous Servicing Facility. Built by Lockheed Martin Space, these two essential parts of the spacecraft will protect the rover during its passage to Mars. The Mars 2020 rover is being manufactured at NASA’s Jet Propulsion Laboratory (JPL) in California and, once complete, will be delivered to Kennedy in mid-February, 2020.
As the spacecraft descends through the Martian atmosphere, the heat shield will encounter extreme amounts of friction, creating temperatures as high as about 3,200 degrees Fahrenheit. The back shell contains several elements critical to landing the rover, including the parachute and antennas for communication. Some of these key components will be integrated in the months to come by the NASA-JPL team at Kennedy.
About the size of a car with dimensions similar to the Curiosity rover, the Mars 2020 rover will carry seven different scientific instruments. Developed under NASA’s Mars Exploration Program, the mission aims to search for signs of past microbial life, characterize the planet’s climate and geology, collect samples for future return to Earth and pave the way for human exploration of Mars.
