ISRO SPADEX satellites' orbits decay; landing date recorded

ISRO's SPADEX mission reached a successful launch milestone on 2024-12-30. The satellites are listed as fuel exhausted and with decayed orbits, and their landing date is recorded as 2026-10-12.

The mission is identified as a successful SPADEX launch by ISRO. SPADEX is listed as the PSLV-C60 payload, and both SPADEX and PSLV-C60 have 2024-12-30 as launch date.

The orbit is stated as a 470 km circular orbit.

The test results include autonomous rendezvous, low-impact docking, vertical docking and radial docking.

Additional test results are composite control, power transfer, undocking, payload operations and circumnavigation.

The satellites are listed as healthy until final telemetry frames, fuel exhausted and orbits decayed. Moderate geomagnetic storms are listed for 2026-10-04 and 2026-10-11, and they accelerated orbital decay.

For readers tracking the lunar industry, the verified SPADEX results cover rendezvous, docking, undocking, power transfer, payload operations and circumnavigation. These are the specific in-orbit functions named in the facts.

The records list a 2026-10-12 landing date for SPADEX-A and SPADEX-B. SPADEX-A is assigned to the South Pacific Ocean, while SPADEX-B is assigned to the North Atlantic Ocean.
