PUNCH News

The four PUNCH spacecraft are now at Vandenberg Space Force Base (VSFB) in California, undergoing final test and integration to the “launch stack” with the SPHEREx spacecraft. All five spacecraft are planned to launch on a Falcon 9 rocket from Vandenberg Space Force Base no earlier than February 27, 2025.

On 15 January, PUNCH passed a combined pre-shipment & operational readiness review, clearing us to ship the four spacecraft and necessary ground equipment from SwRI’s headquarters in San Antonio, TX to to Vandenberg Space Force Base. There they will undergo final integration with the launch carrier, the SPHEREx spacecraft, and a Falcon 9 rocket. The PUNCH team's operational plans, tools, training, and personnel were found to be sufficient to operate and commission the constellation from the Mission Operations Center at SwRI’s offices in Boulder, Colorado. Congratulations to everyone on a hard-fought and hard-won I&T campaign!

We invite the community to the sixth PUNCH (Polarimeter to UNify the Corona and Heliosphere) Science Meeting on February 25th and 26th, 2025 at Cal Poly in San Luis Obispo, CA. Major science topics include the origin and evolution of the ambient solar wind and turbulence within it and the physics, tracking, and predictability of transient events including CMEs, CIRs, and shocks.

The WFI-1 Observatory is now fully integrated! It is the PUNCH fleet leader through environmental testing, which is scheduled to begin this week. On Friday 26-April, the WFI-1 Observatory collected its first science image through the WFI instrument: a team selfie in the Building 299 clean room where PUNCH I&T is proceeding. The image includes the WFI baffle “horizon” (at left, as the Observatory was on its side in the mounting cage), the massive doors into the high bay, one of the other Observatories in the background, and seven team members who were conducting the test. From left to right: Kelly Smith, Jim Foster, Ronnie Killough, Glenn Laurent, Emily Fisher, Brandon Perez, and Tonya Brody, all in cleanroom garb, with another PUNCH spacecraft visible just over Tonya’s shoulder.

The PUNCH PI Craig DeForest and PUNCH Outreach Lead Cherilynn Morrow presented, live at the Cotton Bowl Stadium, the mission and its relevance to solar eclipse viewing and sunwatching across time and space.

After six years in use the PUNCH logo got a makeover in April. The newer rendering is similar to the old, but with some important fixes. The central swoops now reproduce better in more different media. The diffraction spikes on the stars work correctly (all facing the same direction). Additionally, the new render is a scalable SVG file, allowing reproduction on media of all sizes from pop-sockets to Falcon 9 stages.
