Apparently a 17th object cataloged as 53460 / 2022-098S
May be just a debris object, or the CZ-6 third stage.
Of the previous 8 CZ-6 launches, only one - the most recent one - has deorbited
the third stage. Not sure if there is a NOTAM third stage reentry zone?

Booster 1052 came back in recently from the #SpaceX KPLO mission without incident, but the cap went up with only 3 (of 4) cables attached. 1 of those dropped unexpectedly and dented the right leg (which caused its removal) & then the cap went back on without any cables. A 1st.

A closer view of B1052s missing actuator, which was removed after it was accidentally damaged in processing..

Damaged at port or in transit processing?

Thanks very much. TLEs seem consistent with reentry in this area around 0803 UTC Aug 9.

Just found a paywall Ed paper on Y2O3 that hits on its chromatic behavior when added to Zirconia in varying concentrations. Most of the meat is hidden and what is public strains my level of understanding. The references shown may point to something on point for heat tile glaze for those with the skill and interest.


One takeaway: Y2O3 exhibits infrared photoluminescence when laser pumped which explains its high emissivity in the IR. 


https://www.sciencedirect.com/science/article/abs/pii/S0749603608002760


My search also also hit some Chinese patients using Y2O3 as a low concentration element in powdered glass glazes but nothing specifically as a pigment. The text appeared to be google translated and was a trial to understand.


Edit: paywalled, not paywall Ed.

General Discussion / Re: Predictions for 2022 (Five years from 2017)
« Last post by Orbiter on Today at 01:31 am »
So what will be happening in human spaceflight in 2022, five years from now?

Commercial Crew vehicles will be conducting regular crew rotation flights to the ISS.

SpaceX (and possibly Boeing) will fly one tourist flight to LEO (or perhaps around the moon) a year.

ISS extended to at least 2026. Likely 2028.

Blue Origin and Virgin Galactic will be flying regular sub-orbital tourism flights.

SLS/Orion will be gearing up for the EM-2 flight. DSG and a reusable manned lunar lander are under development.

SpaceX will have made good progress on BFR but are years away from a first flight.

This prediction ended up being remarkably accurate, sans EM-2 and Virgin Galactic. Well done.
