Overview
NASA's Pandora mission, the first satellite launched under the Astrophysics Pioneers program, has begun its observations of exoplanets and the stars they orbit. The spacecraft is designed to measure the chemical makeup of planetary atmospheres beyond our solar system.
Over the course of its primary mission, Pandora will target at least twenty distinct exoplanets. Using spectroscopy in visible and near‑infrared wavelengths, it will search for signatures of hazes, clouds, and water vapor in their atmospheres, providing clues about temperature, composition, and potential habitability. Observing multiple transits per target boosts the signal‑to‑noise ratio.
These measurements complement data from larger observatories such as the James Webb Space Telescope by focusing on longer, continuous monitoring of a carefully selected sample. The results will help scientists understand how planetary atmospheres evolve under different stellar environments.
All results are intended to be released to the public, and the mission team expects the first datasets to be available within a year of the start of regular observations through NASA's HEASARC archive. Pandora demonstrates how modest‑cost, high‑impact astrophysics missions can deliver valuable contributions to exoplanet science.
