Boeing’s Spectrolab to Power NASA’s Roman Space Telescope

- Approximately 4,000 XTJ Prime #solarcells will power NASA’s Roman Space Telescope
- Cells will maximize power generation allowing for more generated data
SYLMAR, Calif., April 5, 2022— Spectrolab, Inc., a wholly owned subsidiary of #boeing [NYSE: BA], will manufacture, integrate and test approximately 4,000 XTJ Prime #solarcells for #nasasnancygraceromanspacetelescope.
“Using #Spectrolabsxtjprimesolarcells, NASA will be able to maximize the Roman Space Telescope’s power generation, allowing greater data gathering capability while operating in a unique mission environment at the L2 Lagrange point,” said #tonymueller, president of #Spectrolab. “These cells leverage both heritage and high efficiency for the agency’s newest universe studying telescope.”
Spectrolab’s NeXt Triple Junction (XTJ) Prime #solarcells will provide power to the telescope, including its two main instruments – the Wide Field Instrument and the Coronagraph Instrument – as well as the primary mirror that is 2.4 meters in diameter (7.9 feet), and is the same size as the Hubble Space Telescope's primary mirror. The solar array consists of six panels, each approximately 3m-by-2.5m and consists of 4,000 triple junction #solarcells. Triple junction #solarcells leverage multiple bandgaps tuned to different wavelengths of the solar spectrum, allowing higher efficiencies not possible with commercially available silicon solar cell technology.
Targeted to launch no later than May 2027, NASA’s Roman Space Telescope will investigate long-standing astronomical mysteries, such as the force behind the universe’s expansion, and search for distant planets beyond our solar system. The telescope is named after #nancygraceroman, NASA’s first chief astronomer, who paved the way for space telescopes focused on the broader universe.
“Our versatility in supporting a wide range of NASA human space exploration, Earth observation and solar system missions is something we’re incredibly proud of at #boeing,” said #jimchilton, senior vice president, #boeing Space and Launch. “The on-orbit performance of our innovative solar cell technology to-date proves we can provide more power – and in smaller packages – to customers than ever before.”
As an example, the new International Space Station Roll-Out Solar Arrays (iROSA), which utilize XTJ Prime #solarcells, are producing an additional 120 kilowatts of electricity from the sun’s energy for NASA’s orbiting laboratory – enough to power more than 40 average U.S. homes. #Spectrolab also produced the station’s original #solarcells that have kept the football field sized ISS operating for more than two decades.
Spectrolab has produced more than 6.5 million gallium-arsenide #solarcells for more than 1,000 spacecraft over the last 65 years in a shared vision with customers to connect and protect people globally, enable the exploration of other worlds, and build a space ecosystem for the future.
