India’s Dust EXperiment, or DEX, has recorded repeated strikes from tiny space dust near Earth orbit. The 3-kg device flew on ISRO’s PSLV-C58 XPoSat mission in January 2024 and worked at about 350 km altitude. It was built by the Physical Research Laboratory in Ahmedabad. From January 1 to February 9, the instrument logged clear signals from fast dust particles formed by comet tails and asteroid crashes. Some hits were seen about once every 17 minutes. Scientists say such particles can damage satellites over time. The data will help plan shielding for future missions. (PC: India Today)
