Crews conduct a solar array deployment test on the spacecraft of NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites at Astrotech Space Operations located inside Vandenberg Space Force Base in California on Tuesday, Jan. 21, 2025.USSF 30th Space Wing/Antonio Ramos Technicians supporting NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission deployed and tested the spacecraft’s solar arrays at the Astrotech Space Operations processing facility at Vandenberg Space Force Base in California ahead of its launch next month.
The arrays, essential for powering instruments and systems, mark another milestone in preparing PUNCH for its mission to study the Sun’s outer atmosphere as it transitions into the solar wind. Technicians performed the tests in a specialized cleanroom environment to prevent contamination and protect the sensitive equipment.
Comprised of four suitcase-sized satellites working together as a constellation, PUNCH will capture continuous 3D images of the Sun’s corona and the solar wind’s journey into the solar system. Led by the Southwest Research Institute (SwRI) for NASA, the mission aims to deepen our understanding of the Sun and solar wind and how they affect humanity’s technology on Earth and our continued exploration of the solar system.
Successful solar array testing brings the spacecraft another step toward readiness for launch. The agency’s PUNCH mission is targeting liftoff as a rideshare with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) on a SpaceX Falcon 9 rocket from Vandenberg’s Space Launch Complex 4E no earlier than Thursday, Feb. 27.

NASA’s SPHEREx space observatory was photographed at BAE Systems in Boulder, Colorado, in November 2024 after completing environmental testing. The spacecraft’s three concentric cones help direct heat and light away from the telescope and other components, keeping them cool. Credit: BAE Systems NASA will host a news conference at 12 p.m. EST Friday, Jan. 31, to discuss a new telescope that will improve our understanding of how the universe evolved and search for key ingredients for life in our galaxy.
Agency experts will preview NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission, which will help scientists better understand the structure of the universe, how galaxies form and evolve, and the origins and abundance of water. Launch is targeted for no earlier than Thursday, Feb. 27.
The news conference will be hosted at the agency’s Jet Propulsion Laboratory in Southern California. Watch live on NASA+, as well as JPL’s X and YouTube channels. Learn how to watch NASA content through a variety of platforms, including social media.
Laurie Leshin, director, NASA JPL, will provide opening remarks. Additional briefing participants include:
Shawn Domagal-Goldman, acting director, Astrophysics Division, NASA Headquarters James Fanson, project manager, SPHEREx, NASA JPL Beth Fabinsky, deputy project manager, SPHEREx, NASA JPL Jamie Bock, principal investigator, SPHEREx, Caltech Cesar Marin, SPHEREx integration engineer, Launch Services Program, NASA’s Kennedy Space Center in Florida To ask questions by phone, members of the media must RSVP no later than two hours before the start of the event to: rexana.v.vizza@jpl.nasa.gov. NASA’s media accreditation policy is available online. Questions also can be asked on social media during the briefing using #AskNASA.
The SPHEREx observatory will survey the entire celestial sky in near-infrared light to help answer cosmic questions involving the birth of the universe, and the subsequent development of galaxies. It also will search for ices of water and organic molecules — essentials for life as we know it — in regions where stars are born from gas and dust, as well as disks around stars where new planets could be forming. Astronomers will use the mission to gather data on more than 450 million galaxies, as well as more than 100 million stars in our own Milky Way galaxy.
The space observatory will share its ride on a SpaceX Falcon 9 rocket with NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will lift off from Launch Complex 4E at Vandenberg Space Force Base in Central California.
The SPHEREx mission is managed by NASA JPL for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters in Washington. The principal investigator is based at Caltech in Pasadena, California, which manages NASA JPL for the agency.
The spacecraft is supplied by BAE Systems. The Korea Astronomy and Space Science Institute contributed the non-flight cryogenic test chamber. Mission data will be publicly available through IPAC at Caltech.

Hisdesat, Spain's premier provider of secure satellite communications, is set to launch its SpainSat Next Generation I (SNG I) satellite aboard a SpaceX Falcon 9 rocket on 29 January from Cape Canaveral, Florida at 20:34 EST (30 January at 02:34 CET). The European Space Agency (ESA)-supported satellite will provide more cost-effective, adaptable and secure communication services for governments and emergency response teams across Europe, North and South America, Africa, the Middle East and up to Singapore in Asia.

The Wide-Field Instrument (WFI), the primary instrument aboard NASA’s Nancy Grace Roman Space Telescope, is a 300-megapixel visible and infrared camera that will allow scientists to perform revolutionary astrophysics surveys.
This specialized camera detects faint light across the cosmos and will be used to study a wide range of astrophysics topics including the expansion and acceleration of our universe, planets orbiting other stars in the Milky Way, and far off galaxies.
WFI will conduct surveys to detect and measure billions of stars and galaxies along with rare phenomena that would otherwise be difficult or impossible to find. To survey large areas of sky, WFI uses a suite of 18 detectors that convert incoming light into electrical signals that are translated into images.
While Roman will operate alongside other space telescopes like Hubble, WFI’s capabilities are pushing the boundaries of what is possible. Roman’s WFI has a similar sensitivity and resolution to Hubble, but WFI will capture images that cover about 100 times more sky in a single observation and will survey the sky up to 1,000 times faster.
Artwork Key
1. The Nancy Grace Roman Space Telescope
2. Light Path : The light entering the telescope will take this path, bouncing off of multiple focusing mirrors and passing through filters or dispersers in the element wheel to reach the detectors.
3. Important Years : 1990: NASA’s Hubble Space Telescope launched. 1960: Nancy Grace Roman became NASA’s Chief Astronomer.
4. Field of View : Roman’s field of view is about 100 times larger than that of the infrared camera onboard the Hubble Space Telescope. WFI’s large field of view is achieved using an array of 18 detectors which are represented by the squares in this graphic
5. Detectors : This dial has one tick mark for each of WFI’s 18 detectors.
6. Modes : WFI has imaging and spectroscopy modes.
7. Wavelengths : WFI will observe in both visible and infrared light and can select which wavelengths reach the detectors using filters in the element wheel.
8. “Dark Energy” Drink + “Dark Matter” Candy : Roman will enable new research into the mysteries of dark energy and dark matter.
9. Science Goals : The names of these games capture WFI’s role as a survey instrument and the types of surveys it will perform.
10. Joystick : This joystick features design elements found on the WFI’s element wheel assembly, a large, rotating metal disk with optics that filter or disperse light.
