This week’s mission will be the latest, but not the last, foray into the solar system for Teledyne, which began as part of the Martin Co. ![]() “Really, it’s a time to sit back and enjoy the moment. “Once they’ve got the final flight checks, we sit back and wait for the launch,” Icard said. “It performed well.”įinally, the generator arrived in Florida, where it was the last piece placed into the rocket Monday. “This has been put through the ringer,” Keyser said. There, it received more testing, including a thermal vacuum simulation to ensure its capabilities in space, as well as its nuclear fuel. (The companies are unrelated, despite their similar names.)įrom California, the generator traveled in late 2018 to Idaho National Laboratory. The Perseverance generator was put through a battery of tests to ensure its durability, including vibrating table and electric heat source simulations, at Teledyne before being sent to Aerojet Rocketdyne, the Sacramento, California-based rocket manufacturer, for systems integration. “There’s no plutonium in Hunt Valley,” Keyser said.Ī team of about a dozen Teledyne scientists and engineers, supported by roughly 50 other employees, has been developing the Perseverance rover’s generator in Hunt Valley since 2012, the year the Curiosity rover landed on Mars with its own Teledyne power source, Keyser said. If the concept of nuclear-powered spaceship generators being built and tested in the Baltimore area sounds at all alarming, rest assured that Teledyne manufactures only the hardware. The power source also heats the rover to protect its astrobiology equipment in Mars’ negative 80- to 195-degree temperatures. Instead of relying on sunlight, the generator’s thermoelectric modules convert plutonium-238’s radioactive decay into thermal energy that can last 17 years or more, said Steve Keyser, Teledyne’s MMRTG program manager. When that happens, he said, “there’s not much you can do about it from Earth.”īy contrast, “a dust storm is nothing more than a bad picture day” for Perseverance, he said. The planet’s unpredictable dust storms blocked sunlight and coated the solar panels used to power earlier prototypes, Icard said. The red dust on Mars is one of the main reasons NASA uses nuclear power sources - known as multi-mission radioisotope thermoelectric generators (MMRTGs) - for its rovers. Thursday, weather permitting, at the Cape Canaveral Air Force Station in Florida. The rover and its Baltimore County-built power source will leave Earth at about 10,000 mph aboard a United Launch Alliance Atlas V 541 rocket, scheduled to launch during a two-hour window beginning about 7:50 a.m. “This type of power system enables the scientific community to study the origins of the solar system and potentially find the building blocks of life,” said Mitch Icard,vice president of Teledyne. The roughly 100-pound, 2-foot-tall nuclear generator, designed and manufactured by Teledyne Energy Systems in Hunt Valley, converts plutonium into 110 watts of energy to heat and power the rover as it scours the Red Planet’s Jezero Crater for signs of ancient life. Baltimore Sun eNewspaper Home Page Close MenuĪs one of the final tasks before NASA launches its latest unmanned rover, Perseverance, to Mars on Thursday, a crane hoisted the rover’s power source to the top of the nearly 200-foot-tall rocket and placed it into a hatch just beneath the MARS 2020 logo.
