GOES-R Launch Successful!

This audio is off, it's taking about max q before the rocket lifts off

What?! But why?

It'll come back shortly, don't know why either

Oh, just Kerbal Alarm Clock in action

Centaur MECO, and now we have a three hour coast to apogee.

So, it will fire again to raise the perigee?

Yes, and then Centaur should release GOES-R. The spacecraft will finalize its orbit over a period of time with its onboard kick motor. The second video in the original post is a 6 minute summary of the planned flight profile.

whats all that debris surrounding the satilite, Ice from the upper stage? Any idea how long it would last up there?

[Firemetal]

Yup I saw it. Awesome launch! I absolutely love the five meter fairing configuration launches.

Just to let you guys know, GOES R will use one of the most reliable spacecraft bus, the Lockheed A2100. And it's also the same bus that will be used for the next generation GPS (GPS III) satellites 

Wishes all the best 

Does anyone know why the protective clothing is worn, is it for chemical hazards or to keep dust minimal?

A cleanroom or clean room is an environment, typically used in manufacturing, including of pharmaceutical products or scientific research, as well as aerospace semiconductor engineering applications with a low level of environmental pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors. More accurately, a cleanroom has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. To give perspective, the ambient air outside in a typical urban environment contains 35,000,000 particles per cubic meter in the size range 0.5 μm and larger in diameter, corresponding to an ISO 9 cleanroom, while an ISO 1 cleanroom allows no particles in that size range and only 12 particles per cubic meter of 0.3 μm and smaller.

Thanks for the information, I was leaning my guess more to the cleanliness.

ice should vaporize pretty fast as its just flakes not blocks.

Yes, however you also have protection suits used then dealing with dangerous fuel, its easy to differentiate them the cleanroom suits looks more like medical clothes while the hazmat suits tend to be rubber ones

I couldn't find anything definitive, but I would be very surprised if it wasn't ice. From the two second to the six second mark, there is a chunk that goes tumbling from the lower left to the upper right of the screen that really looks like a small sheet of ice to me. 

As far as to how long it would last, it turns out it might hang around longer than you'd think it would. I found a paper regarding waste dumps from the space shuttle and the ISS, and while the sublimation model they used is for a different shape of ice, it suggests ice particles can sometimes take almost three days to degrade to sub-millimeter sizes. Apparently it was enough of a problem that there was (is?) a mission rule regarding waste dumps on the ISS within three days of a shuttle launch.

I read an article yesterday (which of course I can't find again  ) that said a single fingerprint on the spacecraft within one meter of some of the instruments could prevent them from working properly. 

Edit: Bleh, it was on CNN. . .but hopefully they can at least get a direct quote right.

That makes a lot of sense because our skin does have a slight oil which could cause problems.

Let's hope that the BT-4 thruster will do it's job correctly this time...

Looks like the thruster is working as advertised.

NOVEMBER 23, 2016: Since launch on Saturday, November 19, GOES-R has transitioned to the ‘orbit raising’ phase of the mission and is making its way to geostationary orbit. The spacecraft is currently positioned in a sun-point attitude, which allows its solar array to harness the sun’s power. The GOES-R team has performed the first liquid apogee engine (LAE) burn without anomaly. This engine burn is part of a series of LAEs that will help position GOES-R in geostationary orbit. The next major milestone will be the second stage deployment of GOES-R’s solar array, which is currently scheduled to occur on November 30, 2016.

GOES-R has successfully reached geostationary orbit and is now officially GOES-16. The spacecraft is in good health and has begun returning data. It will now undergo an extended checkout period lasting about one year.
