> Science NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission successfully lifted off from Vandenberg Space Force Base on Wednesday, July 23 at 11:43 p.m. IST aboard a SpaceX Falcon 9 rocket. The launch, delayed by 24 hours due to airspace concerns, marks a significant step in studying the dynamic interactions between the solar wind and Earth's magnetosphere.

These interactions can lead to significant space weather events that impact satellite operations, communication systems, and power grids on Earth. The Falcon 9 rocket carried the TRACERS satellites with a diverse payload. Accompanying the NASA mission were two private spacecraft, LIDE and Skykraft 4, along with three additional NASA-involved missions. Among them was the Relativistic Electron Atmospheric Loss (REAL) cubesat, which will study how high-energy particles in Earth's Van Allen radiation belts are scattered into the atmosphere. The REAL mission aims to replicate this natural scattering process to mitigate the risks posed by these particles, which can damage satellite electronics and interfere with their operations.
