The Pandora mission, co-led by a nationwide laboratory and a NASA flight middle, has handed a vital step on its path to check stars and planets outdoors our photo voltaic system, or exoplanets.
After a profitable idea research report and system necessities evaluate, NASA accredited the mission to proceed towards flight. Lawrence Livermore Nationwide Laboratory (LLNL) and NASA’s Goddard House Flight Heart (GSFC) are co-leading Pandora as a part of NASA’s new Astrophysics Pioneers program, with LLNL main the mission administration and NASA GSFC main the science.
The mission will research roughly 20 stars and exoplanets by analyzing starlight that passes via exoplanets’ atmospheres, utilizing a way referred to as transit spectroscopy.

Pandora will disentangle alerts to grasp that are from exoplanet atmospheres and that are from starspots, stellar phenomena which can be just like sunspots and may contaminate knowledge. The celestial untangling will tackle and mitigate the impression of stellar inhomogeneities on exoplanet knowledge obtained with NASA’s James Webb House Telescope (JWST), which was launched on Christmas Day.
“We’re excited to construct a telescope that can complement massive observatories like JWST,” mentioned Pete Supsinskas, LLNL mission supervisor.
Over the following 21 months, Pandora will mature its mission idea and show that its half-meter telescope is prepared for flight. The mission is leveraging LLNL’s expertise and capabilities in optics design, fabrication and small satellites.
This illustration (to not scale) depicts Pandora’s orbital sample in Solar-synchronous low-Earth orbit, situated roughly 435 to 497 miles (700 to 800 kilometers) above Earth’s floor, because it observes its focused exoplanets and stars. This orbit allows Pandora to acquire a number of observations of exoplanets over lengthy intervals and the Earthshine exclusion zone helps keep away from mirrored gentle from Earth.

“It is a big step as a result of, whereas it’s a small satellite tv for pc, Pandora will ship impactful science for NASA’s astrophysics program,” mentioned Ben Bahney, LLNL’s program chief for House Science and Safety. “And we’re doing it effectively, below unprecedented price range constraints for mission-quality science.”
Pandora is a part of NASA’s Astrophysics Pioneers program, which focuses on small, low-cost, but formidable missions to unlock new secrets and techniques from the cosmos. The mission shall be developed below a $20 million price cap. Integrating LLNL House Science and Safety Program’s aluminum telescope design with industrial merchandise will assist decrease prices.
Pandora is led by Elisa Quintana, principal investigator at GSFC, and Supsinskas at LLNL. Co-investigators from NASA Ames and a number of other universities will present scientific contributions to the mission. It's anticipated to launch in late 2024 or early 2025.
