ISAR Spectrum - Andøya - 2026-04-09 20:00 UTC

I have updated Platform-6’s configuration on the DB.

Furthermore, we have made a TLE based upon the state vector from ISAR:

1 98405U 26072END 26084.88583771  .00000000  00000-0  78483-3 0  9993
2 98405  97.3981 160.9490 0011291 301.2402  22.8277 15.19404090 00012

I have used the same numbering system on the DB.

@yurimdias for which launch time is this TLE?

@fredy This was for the original time of 20:06 UTC, which is not happening anymore now. I’ll update if we have anything from Isar.

It looks like we will wait a little more for this launch:

Isar Aerospace is standing down from today’s launch attempt to evaluate a leak in a composite overwrapped pressure vessel (COPV).

The teams are assessing and will determine next steps.

Daniel Metzler, CEO and Co-Founder Isar Aerospace: “There is no question that we will reach orbit and demonstrate reliable access to space. Scrubs are part of rocket industry; every successful rocket company has been here. Each attempt gives us valuable experience and lessons learned on our path to orbit. Our teams are assessing the matter, and we will be back on the pad ready to launch soon.”
