There are three Atlas V launches on the manifest before OREx, so it's a little early to worry about this.


Not true. Spacecraft shipment to the launch site is less than 6 weeks.

I presume you're saying it's "not true" that it's early to worry about this. The Atlas launch manifest is a matter of public record. Next launch is MUOS-5, which was slipped from 5 May to 12 May for the OA6 anomaly investigation. I wouldn't expect that week to ripple forward all the way to OREx. http://www.spaceflightinsider.com/organiza...muos-5-mission/

If you have an actual source of information that says this is a concern, post it. The spacecraft won't be mated to the LV until about a week/10 days before launch if the Juno experience is any guide.

BTW, http://forum.nasaspaceflight.com/index.php?topic=39920.0 is the best source of information on the Atlas anomaly that I'm aware of.

Here is a story just out for the Atlas problem: Spaceflight Now - Narrowing list of suspects

QUOTE
To give the team ample time to figure out what went wrong and implement any corrective actions, the next Atlas 5 launch has been rescheduled from May 5 to May 12.


Also from the same website is their reported Launch Schedule, which shows Osiris-REX sitting comfortably at September 8th behind three other Atlas 5 launches (and as an aside Bepi-Colombo just got added to their list for January).

I'd really like to see this launch. It's going to have one single solid strap-on. Don't see that often.

I would not recommend googling for it.

SpaceflightNow is not up to date. BepiColombo was silently postponed to a launch in early 2018.

Looks like SBIRS GEO-3 will be leap frogging over O-REX to help preserve its launch period.

Todays Atlas V launch went perfect. Had more solid boosters and engine restarts to worry about than Osiris_REX will have.

The launch of OSIRIS-REX went perfectly. The spacecraft has deployed and is now on its way to Bennu.

Update: Confirmation that both solar panels have deployed.

Kind of surprised that this thread is so quiet. Anyway, thought you all might be interested in this report from an emergency response commander in the 45th Space Wing, writing about the SpaceX explosion (cough, deflagration) that occurred just days before the ORex launch:

"No sooner had we accomplished the securing of the pumps when I was approached by another one of our range users who explained they were losing pressure on the chillers at a neighboring launch complex. Without those chillers the spacecraft for the next launch would be lost. Needless to say at this point I had to reestablish our priorities and get a team working on a way to get our IRT into Space Launch Complex 41 to allow access for technicians to enter in order to make the necessary repairs. As we were reviewing the plan, word came in from Pad 41 that all of the pressures were lost and technicians had to get to the spacecraft immediately. This is a situation when good working relationships with our counterparts at Kennedy Space Center came into play. We were able to coordinate with the KSC EOC for access through their roadblocks and get the required support to the spacecraft in plenty of time to not only save the spacecraft, but to keep the planned launch on schedule. "

Yikes!

Wow. Thanks for sharing that! I'm not clear on what those chillers were chilling and why it threatened OSIRIS-REX...?

My interpretation was this was for the pad air conditioning. Losing A/C could cause contamination concerns but "losing the spacecraft" seems a little overdramatic to me.
