# NASA’s Pandora Mission Begins Study of Exoplanets, Host Stars

Pandora, NASA’s newest exoplanet mission and the first satellite to launch through the agency's Astrophysics Pioneers program, is now making unique observations of worlds beyond our solar system and the stars they orbit. The mission will determine the atmospheric make-up of at least 20 exoplanets, including the presence of hazes, clouds, and water.
“Pandora’s data will help close a major gap in our knowledge about planets and their host stars because, right now, we can’t be entirely sure how the star’s light affects measurements of what makes up exoplanet atmospheres,” said Elisa Quintana, Pandora’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We designed the Pandora spacecraft and its in-depth observing program to better understand this vexing issue.”

The results of the mission will lay a firm foundation for interpreting measurements by NASA’s James Webb Space Telescope, as well as future observatories focused on finding habitable worlds. In fact, Pandora’s near-infrared detector is a spare originally developed for Webb.
"The spacecraft is healthy and all of the instruments are performing as well as we could have hoped,” said Jordan Karburn, Pandora’s deputy project manager at Lawrence Livermore National Laboratory in California. “Our team’s hard work throughout the commissioning process has paid off, and we can now confidently start science."

This artist’s concept summarizes NASA’s Pandora mission and its science goals. Pandora will repeatedly observe multiple planets and their host stars in both visible and near-infrared light. These measurements will enable astronomers to separate chemical fingerprints detected in a planet’s atmosphere from potentially misleading signals originating from its host star.

Launched into low Earth orbit on Jan. 11, Pandora is an ambitious small satellite (SmallSat) funded by NASA’s Astrophysics Pioneers program. Pioneers are designed to explore compelling questions about the universe with fast-paced, low-cost missions that require a higher-than-usual tolerance for failure.
Three factors make Pandora unique. It carries a novel all-aluminum telescope about 18 inches (45 centimeters) in diameter, it will study planets and their host stars simultaneously in both visible and infrared light, and it will observe targets for a much longer time than flagship observatories like Webb are able to.
Telescopes can sample a planet’s atmosphere in systems where the planet passes in front of its star as seen from our perspective. During this event, called a transit, some starlight skims the planet’s atmosphere before making its way to us. As this light interacts with atmospheric molecules, their chemical fingerprints become embedded in it. For each molecule, astronomers see brightness dips at characteristic wavelengths.
But our instruments also see light from the whole star, not just what grazes the planet. Stellar surfaces aren’t uniform. They sport hotter, brighter areas called faculae and cooler, darker regions similar to sunspots. Both can grow, shrink, and change position as the star rotates.
“Water is one of the most important molecules we can measure to understand the composition and physical conditions of an exoplanet atmosphere,” said Benjamin Rackham, a team member at the Massachusetts Institute of Technology in Cambridge. “But features on the star can distort the water signal we’re searching for. Pandora is designed to disentangle the signals from the planet and the star, helping us to understand the planets more accurately and laying the groundwork for the eventual study of planets that could harbor life.”

Pandora’s telescope, jointly developed by Livermore and Corning Specialty Materials in Keene, New Hampshire, and its detectors make up the mission’s heart. The detectors will capture the star’s brightness in visible light and its near-infrared spectrum at the same time, while also obtaining a near-infrared spectrum from the planet when it transits the star. Over the course of its year-long primary mission, Pandora will observe at least 20 exoplanets 10 times with a long-duration stare covering 24 hours, with a transit included in each observation.
“Pandora’s advantage is its ability to observe targets for extended periods at multiple wavelengths, something high-demand flagship missions like Webb cannot regularly do,” said Knicole Colón, the mission’s project scientist at NASA Goddard. “Combining Pandora and Webb data will uniquely enable scientists to determine the properties of stellar surfaces and cleanly separate star and planetary signals.”
Pandora is led by NASA’s Goddard Space Flight Center. Lawrence Livermore National Laboratory provides the mission’s project management and engineering. Pandora’s telescope was manufactured by Corning and developed collaboratively with Livermore, which also developed the imaging detector assemblies, the mission’s control electronics, and all supporting thermal and mechanical subsystems. The infrared sensor was provided by NASA Goddard. Blue Canyon Technologies provided the bus, performed spacecraft assembly, integration and environmental testing, and is providing mission operations support. NASA’s Ames Research Center in California’s Silicon Valley performs the mission’s data processing. Pandora’s science data is available at the NASA Exoplanet Archive, which is operated by IPAC at the California Institute of Technology in Pasadena. The University of Arizona leads mission operations for Pandora and contributes to its science program. Many additional universities also support the science team.
