SpaceX F9 - 1st Block 5 - Bangabandhu-1 - LC-39A

T-26 and the webcast still isn’t live. Hmm...

Webcast is live Bangabandhu Satellite-1 Mission | SpaceX

It seems at this time it is raining on OCISLY

 

[Grendal]

Everyday Astronaut is livestreaming if you prefer commentary on the launch.

 

[Grendal]

Launch hold.

And scrub.

Tomorrow at 4:14 PM Eastern

 

[Electroman]

Abort !

 

[Electroman]

Scrubbed for the day. It seems like false alarm. But we will never know.

Next attempt tomorrow 4:14pm EST

Next attempt tomorrow 4:14pm EST

I think the correct time shoud be 4:14 p.m. EDT, or 20:14 UTC (copied from spacex.com)

 

[Grendal]

Weather is 60% go for tomorrow. Probably part of the reason they pushed for today so hard.

So far, only the rocket knows why there was an abort...

 

[Grendal]

So it was a ground systems fault. Rocket was and is fine....

Standing down today due to a standard ground system auto abort at T-1 min. Rocket and payload are in good health—teams are working towards tomorrow’s backup launch opportunity at 4:14 p.m. EDT, or 20:14 UTC.

I don’t understand what “standard” means in this statement: “...due to a standard ground system auto abort...”.

I don’t understand what “standard” means in this statement: “...due to a standard ground system auto abort...”.

I think that means that there wasn't anything really wrong. However if something isn't registering correctly then the system will call a halt. So if a cable has come loose to a group of sensors then you'd get a halt. It was something with the ground equipment and had nothing to do with registering a fault on the rocket. Maybe we'll get more details tomorrow.

New Webcast:

 

[Grendal]

Nominal liftoff, MECO was good, 1st stage landing!!!, and second stage engine cutoff.

Bad video for 1st stage reentry and recovery but otherwise perfect.

This was one of the best webcasts. It was compelling to see how this satellite will impact the country of Bangladesh and the region.

 

[Electroman]

Sattelite deployed. 100% success!!

25th landing of first stage.

No fairing recovery attempt

 

[miimura]

It looked to me like they changed the cameras mounted on the first and second stages. The color rendering from the second stage was clearly different and the first stage camera was shaking a LOT. Maybe it has a vibration isolation mount, but it made the image really unstable even under small impulses like the cold gas thrusters.

Happy to see another successful mission, the debut of Block 5, AND the 25th stage recovery! Congratulations to SpaceX.

I am probably only one to listen to the leader of country speech. Was surprised to hear “they leased orbit from Russia”. Are orbits owned?

The International Telecommunications Union (ITU) allocates orbits and frequencies to keep some sense of order. I imagine Bangladesh "leased" an orbit and a frequency from the country it had already been assigned to: in this case, Russia.

..and the PM speech was cut off before she could finish - in time to restart the webcast for the reignition of 2nd stage and payload separation
