Discussion Thread for PAZ mission.

NSF Threads for PAZ : Discussion / Updates / L2 Coverage January-February

NSF Threads for Starlink Constellation:  SpaceX FCC filing for a 4425 satellite constellation providing Internet service / SpaceX - now a satellite vendor?

NSF Articles for PAZ :

Feb 21, 2018 on reused Falcon 9 (booster 1038.2) from Vandenberg.  Launch time reported as 1417 UTC, 0617 PST.  First stage may be expended.  PAZ is 1400kg and going to a 514-km polar orbit.  SpaceX is expected to launch their demonstration satellites, Microsat 2a & 2b (a little under 400kg each, plus dispenser?), for the internet constellation on this flight.

Hisdesat, the Spanish government satellite services company, has signed an agreement with U.S. company SpaceX to launch the Earth Observation Radar satellite, PAZ, on board a Falcon 9 rocket. The launch is targeted to take place during the last quarter of 2017, from Space Launch Complex 4E at Vandenberg Air Force Base, California. The numerous successes of Falcon 9 have been a driving factor for the election of Hisdesat to launch on board this rocket, which already has the confidence of other great companies.

Launching of the Spanish PAZ satellite will be carried out with the help of the Falcon 9 rocket from SpaceX company instead of the Russian Dnepr rocket, as planned initially, according to the website of the customer - the Spanish state-owned company Hisdesat.

"Hisdesat signed an agreement with the US company SpaceX to launch the PAZ Earth observation radar on board the Falcon 9 rocket," the report said.

The launch is scheduled for the last quarter of 2017 at the cosmodrome on the territory of the air base Vandenberg in California.

There's going to be a Cosmodrome at VAFB now, cool!

The Spanish text doesn't call it a cosmodrome. The English page has a funky translation, I guess.

How did Hisdesat get a launch lined up for 2017, given SpaceX's backlog?

Is this going to rideshare with Formosat, maybe?

Peter Selding reported that PAZ will have a co-passenger, but doesn't know who yet:

Can we speculate that it will use a reflown S1?

With Shotwell stating 5 more flights with reused boosters this year I wouldn't bet against it.

If true, second stages are not/will not be the pacing item -- otherwise, this payload would have to wait in queue for its second stage.  Launch pad slots seem to be pacing today.  After the next handful of flights, or at least by LC-40 return to service, they drop back to first stages being limiting.  Reflights can then become fillers between new cores.

Speculation about whether the flight could reuse a booster is really not appropriate in every mission thread that gets created.  If we get any actual indication that the flight will reuse a booster then you can discuss it here.  Otherwise, maybe stick to a general reuse thread.

This is a very likely candidate to be the first RTLS (Return to Launch Site) for F9 at Vandenberg.  With only 1400 kg to sun synchronous orbit, it seems it would have the propellant to do so.

[SpaceNews] Spire, 40 cubesats in orbit, competing more directly in space-based ship-tracking market

exactEarth has 65 hosted payloads launching on Iridium Next satellites, spokesperson Nicole Schill told SpaceNews Aug. 31...The company has one more first-generation payload awaiting launch on the long-delayed PAZ satellite that investor Hisdesat of Spain recently shifted from Kosmotras to SpaceX. Schill said PAZ is expected to launch in December 2017;

I don't see how all of these launches set for December 2017 are actually going to launch in December 2017.  Who knows, maybe SpaceX can pull it off.  It would be nice if this launched in December, Vandenberg is gonna get busy next year.

When the award announcement to launch interval is this short, and the well-established* queue is jumped, I think the reality is that a reuse core is indicated.  Not random speculation, unless there is a better explanation...

* I'm assuming that queue published in this section is well-sourced and reasonably reliable.

When I wrote that 5 1/2 months ago people were asking that question in every mission thread created, no matter how far in the future it was.

I think this has a good shot of launching in December because there isn't another flight out of Vandy scheduled for that month. The 5th Iridium launch is almost certainly January 2018 now with the slip of the 3rd Iridium to October (if that wasn't clear earlier).

Sorry, missed the date line.

This is a very likely candidate to be the first RTLS (Return to Launch Site) for F9 at Vandenberg.  With only 1400 kg to sun synchronous orbit, it seems it would have the propellant to do so.

Formosat was about 450kg to SSO and it didn't even do a boostback ASDS landing. Unless they just decided "Why not, let's just do a crazy entry burn with no boostback", this will likely not be RTLS.

RTLS was not done because they have not been approved to use the LZ. Somebody with more knowledge will have to say whether it was possible had LZ use been approved, but either way it wasn't going to happen.

See the final 5 paragraphs of this article:  https://www.nasaspaceflight.com/2017/08/spacex-static-fire-formosat-5-falcon-9-asds-landing/

That means that, unless the landing facilities are still incomplete, they could theoretically do RTLS for any launch that has the excess performance to do so.

Based on the brief glimpses of the landing pad from various Formosat-5 launch videos and pictures, it appeared to not yet be painted indicating it is not yet ready to go.
