PSLV-C62's third-stage anomaly, the CE20 hot-fired at 22 tonnes for LVM3 M7, and EOS-05's climb to geostationary finished

The CE20 for LVM3 M7 passes its flight-acceptance hot test at 22 tonnes. ISRO has run the flight-acceptance hot test — a ground firing of the actual engine that will fly — on the CE20 cryogenic engine assigned to LVM3 M7, the seventh operational flight of the Launch Vehicle Mark-3. The firing, at the ISRO Propulsion Complex in Mahendragiri, was done at the uprated 22-tonne thrust level planned for future C32 cryogenic stages, and it cleared every objective. Two programmes lean on this engine: the uprated CE20 is what future LVM3 upper stages will fly, and LVM3 is the rocket assigned to Gaganyaan, India's crewed programme — the same test also demonstrated the LOX (liquid oxygen) tank pressurization module built for the Gaganyaan stages. A clean acceptance firing moves M7 toward its launch campaign. The test ran on Wednesday 9 September 2026; the engine will be refurbished and built into the C32 flight stage for M7, scheduled for the fourth quarter of 2026. ISRO

EOS-05 completes its three-burn climb toward the 85.5° East slot. EOS-05 has finished orbit-raising: ISRO reports three burns of the spacecraft's LAM (liquid apogee motor) between Saturday 5 and Monday 7 September 2026, the last of them lifting the low point of the orbit and leaving the satellite healthy in an estimated 34,903 km x 35,884 km. The destination is a geostationary slot at 85.5° East. For a satellite bound for geostationary orbit, the post-launch climb is where missions are quietly won or lost: every burn spends propellant the spacecraft will never get back, and a misfire here can gut the mission's margin. Three clean burns with the spacecraft reported healthy is the 'going nominally' checkpoint for anyone tracking missions in flight. The first burn alone ran 5,406.4 seconds; the second, 338.9 seconds, raised the apogee to 35,786 km; the third ran 1,247 seconds and raised the perigee. ISRO
