вЂњWeвЂ™re pleased to be passing another milestone with the completion of the Flight Readiness Review,вЂќ said Matt Wallace, deputy project manager for the mission at NASAвЂ™s Jet Propulsion Laboratory in Southern California. NASA managers cleared teams to proceed with final preparations for the Perseverance roverвЂ™s launch during a Flight Readiness Review Wednesday. The Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG, for the Perseverance rover is pictured before fueling with plutonium.

Dragonfly is scheduled to launch in 2026. NASAвЂ™s Dragonfly mission, which will send a flying quadcopter to SaturnвЂ™s moon Titan, is the space agencyвЂ™s next probe that will be powered by an MMRTG. NASA and the Department of Energy announced in 2013 that plutonium-238 production had resumed at Oak Ridge National Laboratory in Tennessee, helping ensure nuclear power generators are available for future deep space missions. government purchased the material from Russia from 1992 until the late 2000s. The United States halted production of plutonium-238 in 1988, andВ the U.S. The MMRTG for the Perseverance rover includes a small amount of plutonium-238 produced by the Department of Energy in recent years. The samples will be sealed in ultra-clean tubes for return to Earth by a future robotic mission. One primary goal for NASAвЂ™s new Mars rover is the collection of rock samples using a coring drill. The Ingenuity helicopter - with spinning blades spanning about 4 feet (1.2 meters) in diameter - will attempt to become the first rotorcraft to fly in the atmosphere of another planet.

18, 2021, the rover will deploy the solar-powered drone for a series of test flights. NASAвЂ™s Ingenuity Mars Helicopter is also accompanying the Perseverance rover to the Red Planet. Perseverance carries an upgraded suite of scientific instruments, including improved cameras and a payload to demonstrate producing oxygen from carbon dioxide in Martian atmosphere, a key capability for future human expeditions. The one-ton Perseverance rover is a near-clone of NASAвЂ™s Curiosity rover, which launched in 2011 and landed on Mars in August 2012. The MMRTG is the latest in a line of nuclear power sources and heaters used on more than 30 U.S. That will help keep the Perseverance roverвЂ™s internal electronics warm in the cold temperatures at the Martian surface. Nearly 95 percent of the energy produced by the MMRTG will be in the form of excess heat. The batteries will power the robot during times of peak power usage, when NASA says power demand can reach 900 watts during science operations on Mars. The MMRTG will charge two lithium-ion batteries on the Perseverance rover.

The MMRTGвЂ™s power efficiency declines by a few percent per year. The device produces about 110 watts of power at the start of PerseveranceвЂ™s mission, roughly equivalent to the power draw of a light bulb.

The generator contains 10.6 pounds (4.8 kilograms) of plutonium dioxide fuel. Department of Energy, the MMRTG works by converting heat from the natural radioactive decay of plutonium-238 - a special non-weapons grade isotope of plutonium - into electricity. вЂњThe launch operations team will continue to monitor the health of the spacecraft to ensure itвЂ™s вЂgoвЂ™ for launch - nothing glamorous, but an important part of the job.вЂќДeveloped by the U.S. вЂњAt this point, the spacecraft has been powered on and will remain so around the clock,вЂќ said Dave Gruel, manager of Assembly, Test and Launch Operations, or ATLO, for the Mars 2020 mission. The rover is the centerpiece of NASAвЂ™s $2.4 billion Mars 2020 mission. The power source was the final major component to be added to the Perseverance rover before its scheduled launch next week. The 99-pound (45-kilogram) unit was installed onto the rover Monday, according to Mary MacLaughlin, a NASA spokesperson.ДЄfter connecting mounting bolts and mating electrical lines, ground crews powered up the rover using the newly-installed MMRTG. Technicians inserted the power generator through an access door on the Atlas 5вЂ™s payload shroud, then placed the device on the aft end of the Perseverance rover throughВ an opening on the spacecraftвЂ™s backshell, which encloses the rover and its landing system during the journey from Earth to Mars. The roverвЂ™s Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG, was transferred from a preparation building to the Atlas 5 rocketвЂ™s Vertical Integration Facility, and was hoisted by crane onto a work platform near the top of the 197-foot-tall (60-meter) launcher. The nuclear power generator for NASAвЂ™s Perseverance rover has been installed on the spacecraft atop an Atlas 5 rocket at Cape Canaveral, and mission managers gave a green light Wednesday to continue preparations for the roverвЂ™s July 30 launch toward Mars.
