NASA's TRACERS Satellites Begin Solar Wind Study Despite SV1 Glitch
NASA launched its twin TRACERS satellites on July 23, 2025, to study how solar wind causes magnetic reconnection in Earth's magnetosphere. However, a power issue on one spacecraft, SV1, has caused intermittent communication. Engineers believe the issue relates to sunlight availability on its solar panels and plan recovery efforts in August. Meanwhile, the second satellite, SV2, is healthy and undergoing final instrument commissioning. Once ready, SV2 will begin its science mission independently, while NASA works to recover SV1 and resume full dual-satellite operations critical to the mission’s original research goals.
