NASA will provide live coverage of prelaunch and launch activities for SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer), the agency’s newest space telescope. This will lift off with another NASA mission, Polarimeter to Unify the Corona and Heliosphere, or PUNCH, which will study the Sun’s solar wind.
The launch window opens at 10:09 p.m. EST (7:09 p.m. PST) Thursday, Feb. 27, for the SpaceX Falcon 9 rocket that will lift off from Space Launch Complex 4 East at Vandenberg Space Force Base in California. Watch coverage on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.
The SPHEREx mission will improve our understanding of how the universe evolved and search for key ingredients for life in our galaxy.
The four small spacecraft that comprise PUNCH will observe the Sun’s corona as it transitions into solar wind.
The deadline for media accreditation for in-person coverage of this launch has passed. NASA’s media credentialing policy is available online. For questions about media accreditation, please email: ksc-media-accreditat@mail.nasa.gov.
NASA’s mission coverage is as follows (all times Eastern and subject to change based on real-time operations):

Credit: NASA NASA’s Small Spacecraft Systems Virtual Institute (S3VI) is pleased to announce the official release of the highly anticipated 2024 State-of-the-Art Small Spacecraft Technology report. This significant accomplishment was made possible by the contributions of numerous dedicated people across NASA who graciously supported the preparation of the document as authors and reviewers. We also want to extend our gratitude to all the companies, universities, and organizations that provided content for this report.
The 2024 report can be found online at https://www.nasa.gov/smallsat-institute/sst-soa. The report is also available in PDF format as a single document containing all report content as well as individual chapters available on their respective chapter webpages. This 2024 edition reflects updates in several chapters to include: the Formation Flying and Rendezvous and Proximity Operations section within the “Guidance, Navigation, and Control” chapter; the Additive Manufacturing section within the “Structures, Materials, and Mechanisms” chapter; the Free Space Optical Communications section within the “Communications” chapter; and the Hosted Orbital Services section within the “Complete Spacecraft Platforms” chapter.
As in previous editions, the report contains a general overview of current state-of-the-art SmallSat technologies and their development status as discussed in open literature. The report is not intended to be an exhaustive representation of all technologies currently available to the small spacecraft community, nor does the inclusion of technologies in the report serve as an endorsement by NASA. Sources of publicly available date commonly used as sources in the development of the report include manufacturer datasheets, press releases, conference papers, journal papers, public filings with government agencies, and news articles. Readers are highly encouraged to reach out to companies for further information regarding the performance and maturity of described technologies of interest. During the report’s development, companies were encouraged to release test information and flight data when possible so it may be appropriately captured. It should be noted that technology maturity designations may vary with change to payload, mission requirements, reliability considerations, and the associated test/flight environment in which performance was demonstrated.
Suggestions or corrections to the 2024 report toward a subsequent edition, should be submitted to the NASA Small Spacecraft Systems Virtual Institute Agency-SmallSat-Institute@mail.nasa.gov for consideration prior to the publication of the future edition. When submitting suggestions or corrections, please cite appropriate publicly accessible references. Private correspondence is not considered an adequate reference. Efforts are underway for the 2025 report and organizations are invited to submit technologies for consideration for inclusion by August 1, 2025.
NASA’s Small Spacecraft Technology program within the Space Technology Mission Directorate funds the Small Spacecraft Systems Virtual Institute.
