The agency’s PUNCH mission is a constellation of four small satellites. When they arrive in low Earth orbit, the satellites will make global, 3D observations of the Sun’s outer atmosphere, the corona, and help NASA learn how the mass and energy there become solar wind. By imaging the Sun’s corona and the solar wind together, scientists hope to better understand the entire inner heliosphere – Sun, solar wind, and Earth – as a single connected system.
The PUNCH mission will share a ride to space with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) space telescope on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
The Southwest Research Institute in Boulder, Colorado, leads the PUNCH mission. The mission is managed by the Explorers Program Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington.

The coronagraph will have a similar field of view as the SOHO (Solar and Heliospheric Observatory) Large Angle and Spectrometric Coronagraph (LASCO) C3 field, from 6 to 32 solar radii on the sky, and it will view the corona in both polarized and unpolarized light.Wide Field Imager (WFI)The Wide Field Imager (WFI) is a heliospheric imager, a device that provides views from 18 to 180 solar radii (45 degrees) away from the Sun in the sky. Heliospheric imagers use an artificial “horizon” and deep baffles to view the very faint outermost portion of the solar corona and the solar wind itself. The instrument reduces direct sunlight by over 16 orders of magnitude, which is like the ratio between the mass of a human and the mass of a cold virus. The wide-field imaging optics are based on the design of the famous Nagler eyepieces, which are known among observational astronomers for their clarity, low distortion, wide field, and achromatic focus. Three of the PUNCH spacecraft will carry a WFI instrument. || ", "release_date": "2025-01-24T14:00:00-05:00", "update_date": "2025-02-11T10:08:04.490942-05:00", "main_image": { "id": 1141548, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a014700/a014771/NFI_LEO_Animation.00001_print.jpg", "filename": "NFI_LEO_Animation.00001_print.jpg", "media_type": "Image", "alt_text": "Animation depicting the PUNCH Narrow Field Imager, or NFI instrument, from low Earth orbit.
