A new launch date on April 18 is now confirmed. However, the weather forecast only gives a 40 % probability of favorable launch weather. Saturday 19 will be the backup date with a 70 % chance of good weather.
Jesper and I will watch it from Denmark as we left Florida yesterday.
The launch window for the ISS closes on April 22 until June. A new scrubbed launch will therefore mean another two month delay.
