NASA announced on August 25, 2026, that Pandora had begun science observations, following its January 11 launch into low Earth orbit. The small space telescope studies planets outside the solar system together with the stars that illuminate them. Its observing program is designed to separate atmospheric features from changes in the starlight used to measure them.
The spacecraft carries a 45-centimeter aluminum telescope and observes visible and near-infrared light simultaneously. NASA reported that the spacecraft was healthy and its instruments were performing as expected after commissioning. Its near-infrared sensor was originally developed as a spare for the James Webb Space Telescope.
Pandora’s primary observing plan covers at least 20 exoplanets over one year. Each receives 10 observing visits lasting 24 hours, including a passage across its star. These long observations give researchers measurements before, during, and after the planet blocks a small fraction of the star’s light.
Separating Stars From Planetary Atmospheres
The mission’s measurement method depends on transits, the passages of planets in front of their stars from the telescope’s viewpoint. A small portion of the star’s light travels through the planet’s atmosphere. Molecules absorb particular wavelengths, producing patterns that researchers compare with measurements of the unobstructed star.
The star itself changes that comparison. Cooler spots and brighter regions on its surface can alter the mix of wavelengths reaching the telescope. As the star rotates, those regions move into and out of view. A feature associated with the star can resemble or obscure a feature attributed to the planet.
Pandora measures both objects during the same observing sequence. Visible-light measurements track changes in stellar brightness, and near-infrared measurements record information relevant to atmospheric composition. Repeated visits sample how the stellar contribution changes between transits.
New Space Economy’s earlier account of Pandora’s observing strategy described why this sustained monitoring complements larger observatories. A telescope assigned to many competing investigations has limited time for repeatedly watching the same star. Pandora concentrates its program on that task, supplying measurements that can be combined with more detailed observations from Webb.
From Engineering Images to Science Data
NASA’s mission page includes engineering images obtained on January 20. The visible-light test covered a field in Virgo. The infrared test recorded dispersed starlight, providing an early check of the optical and detector systems before the later science announcement.
The mission brings together a federal laboratory, NASA centers, a university operations team, and commercial spacecraft suppliers. NASA Goddard leads Pandora; Lawrence Livermore National Laboratory manages the project and engineering. The University of Arizona leads mission operations, and NASA Ames processes the data.
This arrangement connects telescope observations with a public research archive. NASA makes Pandora’s science data available through the NASA Exoplanet Archive, allowing researchers to use the measurements in studies of planetary atmospheres and stellar activity.
