This follows previous launch attempts back in January and March, April, and June. Fifth time's the charm?

Second test flight of the Isar Spectrum launch vehicle. This launch will carry 5 cubesats and 1 non-separable experiment as part of European Space Agency (ESA)'s “Boost!” program:

• CyBEEsat (TU Berlin)
• TriSat-S (University of Maribor)
• Platform 6 (EnduroSat)
• FramSat-1 (NTNU)
• SpaceTeamSat1 (TU Wien Space Team)
• Let It Go (Dcubed, non-separable experiment)

Propellant load is underway.

T-0 has slipped to 20:12 UTC, 22:12 local.

Liftoff!

Spectrum has passed Max-Q.

MECO, stage separation, and upper stage ignition.

Fairing separation confirmed.

SECO, tentative 500 x 180 km orbit.

There is still a scheduled circularization burn.

Wow, that was awesome! The views from orbit were great, too!

ISAR have now confirmed Spectrum's orbit circularization burn. Hopefully we'll get US Space Force TLE data tomorrow to provide independent confirmation of the orbit.

Six objects cataloged in a 520 x 600 km x 97.4 deg, 1036 LTDN sun-sync orbit consistent with launch from Andoya, confirming success of the ISAR Spectrum launch, although suggesting that stage 2 may not have performed a deorbit burn.
