TRACERS will be the second NASA mission launched from Vandenberg SFB in 2025, following the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer mission launched in March. Vandenberg SFB continues to help meet the space launch needs of the United States, propelling scientific and technological innovation while fulfilling the requirements for the Space Force and its mission partners. Dr. Joseph Westlake, NASA’s heliophysics division director, talks with the Vandenberg Space Force Base community during a brief for NASA’s Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites mission at the Vandenberg SFB and Missile Technology Center, Calif., July 21, 2025. Westlake answered questions from attendees, discussing the long-term goals of the TRACERS mission. NASA’s TRACERS mission will help researchers understand magnetic reconnection and its effects in Earth’s atmosphere. Magnetic reconnection occurs when activity from the sun interacts with Earth’s magnetic field. By understanding this process, scientists will be able to better understand and prepare for the impact of solar activity on Earth. (U.S. Space Force photo by 2nd Lt.
