Chronology

Mission timeline

  1. Launch

    Aditya-L1 launched

    ISRO reports injection into an Earth elliptical orbit of 235 x 19,500 km after a flight duration of 63 minutes 20 seconds. The report gives the launch time as 11:50 IST; the UTC event timestamp converts that local time and retains minute precision.

  2. Milestone

    First Earth-bound maneuver

    ISRO reports the new orbit as 245 km by 22,459 km.

    Earth

  3. Milestone

    Second Earth-bound maneuver

    ISRO reports the new orbit as 282 km by 40,225 km.

  4. Milestone

    Third Earth-bound maneuver

    ISRO reports the new orbit as 296 km by 71,767 km.

  5. Milestone

    Fourth Earth-bound maneuver

    ISRO reports the new orbit as 256 km by 121,973 km.

  6. Departure

    Trans-L1 injection

    ISRO identifies the fifth liquid-engine burn as the Trans-L1 injection maneuver. The maneuver began the transfer toward Sun-Earth L1; no exact time or state vector is supplied by this source.

  7. Milestone

    First trajectory correction maneuver

    ISRO’s mission timeline dates TCM-1 to October 6, 2023; the separate halo-insertion release dates it to October 5. ISRO reports a burn of about 16 seconds. The exact UTC epoch and state change are not published in these sources, and the one-day date conflict remains unresolved.

  8. Milestone

    Second trajectory correction maneuver

    ISRO reports TCM-2 on December 14, 2023, to meet halo-orbit insertion conditions. The source gives no exact time or state change.

  9. Orbit insertion

    Halo-orbit insertion

    ISRO reports insertion at approximately 16:00 IST. The reported target halo-orbit semi-axes are 209,200 km, 663,200 km, and 120,000 km; these are design parameters, not a complete trajectory state.
