What is the T1H-1 mission?
First low-altitude hop test of a Themis demonstrator, with a targeted altitude up to 100 m.
How is this verdict calculated?
The launch starts at 100 points and loses points for sustained wind, gusts, cloud cover, chance of precipitation and thunderstorm energy at Esrange Space Center at the launch hour. 75–100 is GO, 50–74 is CAUTION, below 50 is NO-GO. This is an independent, indicative assessment, not the provider's official launch commit criteria.
