Three objects have not been cataloged yet. Object B has not been found, but is presumed to be out there.

We don't have three yet, but given we have A, a gap, and then C, it's not a huge leap of inference that STRATCOM expects to find a B to put in the middle

In particular: *why* is there a gap for a B? Either they (STRATCOM) are tracking a B, but haven't got a good enough orbit for it yet to issue a TLE; or - more likely I think - they have direct information from SpaceX that a B payload
was expected.

The other possibility is that C is a small debris object and they haven't managed to find the second stage yet, so they're saving B for that.

It may take a few days for things to clarify.

No object B TLEs yet as of 0630 UTC Mar 7 (to qualify this post as an update!)

For people curious about rocket performance: A final orbit as described above is -1990m/s from geo with a 6092kg payload.

(a) should this go in discussion? I'm only replying to it here since that's where it was posted.
(b) How did you get this number? Everyone else who has given this a try has got about 2115 m/s to go. (312 to get to GEO apogee, 1805 from there...)

I do believe you can do combined burns to get a more efficient transfer.

TLEs now available for object B, but it's not identified yet. A is the payload, C is the rocket.

Updates. Discussion. Differences between them. Discuss (but not here).

gwiz · « **Reply #150 on:** 03/08/2018 03:54 pm »

Object B now identified as Podsat, presumably what's described here:

Ride-share confirmed.

Statement to me from Wendy Lewis, Director of Communications, Space Systems Loral.

“An innovative secondary payload release system was successfully tested on Hispasat 30W-6. This was an R&D mission not related to the ongoing operation of the Hispasat satellite. Rideshare arrangements such as this are becoming more common as they help defray the cost of launch and drive innovation for our industry. We are very optimistic about the potential of this release system as part of SSL's future R&D roadmap.”

On Mar 12, Hispasat 30W-6 completed raising its initially subsync apogee to GEO height; on Mar 13 it began perigee raising/inc lowering, now in 5524 x 35905 km x 13.8 deg

HISPASAT 30W-6 performed next two apogee burns to perigee raising and inclination lowering to GEO
