Back to the commentators talking about the launch.

I'm a bit surprised by the lack of ground stations available for telemetry. They won't know if the payload is placed into the right orbit for another 40 minutes, it seems.

Assuming all is well......

S/C Sep!

Many thanks to Chris for the great coverage and as always Steven for his coverage on the thread.

Diego Garcia AOS of payload at T+42mins, or 02:46 EDT (06:46 GMT) according to what was said on the broadcast.

LD loop -- I think -- is still active.  Gonna stay on and see what I hear at T+42mins... or, you know, until the call drops me.

Anyone catch the full T-0 time in the Zulu callout for US Launch Schedule Update on NSF??

That's quite a gap after the LOS from Ascension Island

Launch time was 2:04:00.224

And when did the call drop me, you ask?  Why at T+41mins 56secs.

Anyway, great coverage.  Now... to bed (as that's applicable in my timezone.)

Orbital ATK Twitter says they had spacecraft separation 14 minutes ago. Not sure if that was confirmed by telemetry.

We have spacecraft separation! #ORS5 is now in orbit. This completes the Minotaur IV portion of the ORS-5 mission

Remember inclination is zero. So all ground stations for it have to be on the equator. That limits you a bit!

Looks like Orbital ATK press people are going to bed!

That's a wrap! Thanks to everyone who tuned in to our social media accounts & our live broadcast for our #MinotaurIV launch of #ORS5

There's a tracking station in Malindi, Kenya but it's an ESA asset

Great fun to follow this launch.  I don't like them being all happy happy and giving congrats before spacecraft sep is confirmed by telemetry.  It strikes me as unprofessional and cheap to not hold off a couple more minutes.  It makes them look bad even at their moment of claimed success.  A few more minutes and it would have had a completely different feel.  #making a great moment feel hollow

Agreed. I still haven't seen a credible confirmation of mission success.
