NASA’s SPHEREx, PUNCH Spacecraft Encapsulated as Launch Nears

Technicians and engineers encapsulate NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory and PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites within a protective payload fairing inside the Astrotech Space Operations facility at Vandenberg Space Force Base in California, on Thursday, Feb. 27, 2025.   SPHEREx will use its telescope to provide an all-sky spectral survey, creating a 3D map of the entire sky to help scientists investigate the origins of our universe. PUNCH will study origins of the Sun’s outflow of material, or the solar wind, capturing continuous 3D images of the Sun’s corona and the solar wind’s journey into the solar system. Liftoff aboard a SpaceX Falcon 9 rocket is targeted for NET 10:09 EST (7:09 p.m. PST), Tuesday, March 4, 2025, at Space Launch Complex 4 East from Vandenberg Space Force Base in California.

Technicians and engineers completed encapsulation of NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory and PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites within a protective payload fairing inside the Astrotech Space Operations facility at Vandenberg Space Force Base in California, on Sunday, March 2. 

The payload fairing serves as a barrier to the harsh environment of the atmosphere during launch and ascent. Liftoff of SPHEREx and PUNCH on the SpaceX Falcon 9 rocket is targeted for no earlier than 7:09 p.m. PST (10:09 p.m. EST) on Thursday, March 6. 

The SPHEREx observatory is 8.5 feet tall, 10.5 feet wide and deep, with a solar panel that produces around 750 watts of power. The PUNCH mission features four 140-pound small satellites, each about 1-by-2-by-3 feet in size. At launch, the integrated SPHEREx and PUNCH stack will weigh around 1,667 pounds.  

The SPHEREx mission will view the sky in infrared light, a range of wavelengths not visible to the human eye, collecting data on more than 450 million galaxies along with more than 100 million stars in the Milky Way over a two-year planned mission. PUNCH will study origins of the Sun’s outflow of material, or the solar wind, capturing continuous 3D images of the Sun’s corona and the solar wind’s journey into the solar system.

The four small satellites of NASA’s PUNCH mission arrived Saturday, Jan. 18, at Astrotech Space Operations located at Vandenberg Space Force Base in California for final processing before launch. 

PUNCH (Polarimeter to Unify the Corona and Heliosphere) is sharing a ride to space with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) space telescope which is targeted to launch no earlier than the end of February, on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East (SLC-4E) at Vandenberg space Force Base.  

As part of final tests and checkouts, teams will test the solar arrays on each small satellite before they are mated to SPHEREx in preparation for encapsulation in Falcon 9’s payload fairings.

The PUNCH mission will deploy four suitcase-sized satellites  to observe the Sun and space with a combined field of view. Working together, the four PUNCH satellites will map out the region where the Sun’s outer atmosphere, the corona, transitions to the solar wind, the constant outflow of material from the Sun.

PUNCH is led by Southwest Research Institute’s offices in San Antonio, Texas, and Boulder, Colorado. 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.  

NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the launch service for the missions.

NASA’s SPHEREx spacecraft arrived Tuesday, Jan. 14, at Astrotech Space Operations located inside Vandenberg Space Force Base in California for final processing before launching on its two-year mission. 

The SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory is targeted to launch at the end of February on a SpaceX Falcon 9 rocket from Space Launch Complex 4E. 

Following launch, SPHEREx will support NASA’s goals of discovering the secrets of the universe and searching for the ingredients for life elsewhere. The telescope will scan the sky in the infrared spectrum from a position in Earth orbit and complete four all-sky maps. These will allow scientists to learn about a variety of topics, including the origins of water on planets like Earth, to the physics that governed the universe less than one second after its birth.   

After final tests and checkouts, teams will mate SPHEREx and its rideshare PUNCH (Polarimeter to Unify the Corona and Heliosphere) in preparation for encapsulation in the payload fairings of the Falcon 9 rocket.
