The GSLV-F10/EOS-03 Mission lifted-off normally from Sriharikota on 12 August 2021 at 0013 UTC after a smooth countdown of 26 hours. In the flight, the performance of the first stage (GS1), the strap-on stages (L40) and the second stage (GS2) were satisfactory and in accordance with the pre-flight predictions. However, the onboard computer aborted the mission at 307 seconds into the flight leading to mission failure.

The launch of Astra’s 3.3 rocket (LV 0008) ended in failure on 10 February. After a nominal first stage flight, an anomaly occurred during the stage separation process which resulted in the upper stage not reaching orbit and the end of the mission. Astra said its investigation verified that the payload fairing did not fully deploy prior to upper stage ignition due to an electrical issue.

The launch of Astra’s 3.3 rocket (LV 0008) ended in failure for a reason yet unknown. The rocket appeared to have reached an altitude of 104 km and then experienced a malfunction, sending the second stage tumbling after separation. Further details were not available at the time of writing this.

Copernicus Sentinel-1B is unavailable since 23 December 2021 at 0653 UTC, no data are being generated. Following the anomaly, resuming of the operations was carefully prepared including on-board configuration changes preventing the anomaly to occur again.

The inquiry commission looking into the failure of South Korea’s first Nuri rocket has identified a design flaw as the root cause for the launcher’s failure to enter orbit.

Iran’s rocket launch on 30 December 2021, 0330 UTC from the Imam Khomeini Space Centre failed to put its three payloads into orbit after the rocket was unable to reach the required speed, a defence ministry spokesman said in remarks carried on state television.

Rocket: Angara A5/Persei; Payload: mass simulator; Date: 27 December 2021, 1900 UTC; Launch site: Plesetsk, Russia. While the rocket flew successfully, the newly developed Persei upper stage reportedly failed to place the dummy satellite into near-geostationary orbit.
