1/x It is with great pleasure that I can announce that the Working Group on Small Body Nomenclature of @IAU_org has decided that asteroid (563318) will henceforth be named:
(563318) ten Kate
After the Dutch @UniUtrecht astrobiologist/planetary scientist Dr @ingeloes ten Kate
2/x The naming citation for (563318) ten Kate was published yesterday in IAU-WGSBN Bulletin vol 1. nr 10, p 7: wgsbn-iau.org/files/Bulletin…
3/x Dr Inge Loes ten Kate is a well know researcher into the processes that brought carbon to Mars, through Carbonaceous meteorites and their degradation in the Martian environment, with a focus on the potential creation of Martian environments suitable for (simple) life.
4/x (563318) ten Kate was discovered on 27 Oct 2014 by Krisztián Sárneczky and me (as object "SaLa101") with the 0.6-meter Schmidt telescope of MPC 461 Piszkéstető Observatory located in the Matra mountains of Hungary.
This is an animated GIF of the discovery images:
4/x (563318) ten Kate received the temporary designation 2016 CD144 two years later, and its permanent number (563318) this July (meaning the orbit is well-established enough now that it does not get lost).
We the discoverers then have the privilege to propose a name to the IAU.
5/x Asteroid (563318) ten Kate is somewhere between 0.9 and 2.1 km in diameter. It is a Main Belt IIb asteroid orbiting in the asteroid belt between Mars and Jupiter. One orbit around the sun takes the asteroid about 4.6 years

2/x ...maar worden echt in een baan om de aarde gebracht, zoals een satelliet. Waarna op een gegeven moment met een deorbit burn door een retroraket, de lading weer omlaag wordt gebracht, boven het doelwit.
Welnu: waarom zou je dit zo doen in plaats van een normale ICBM lanceren?
3/x Het voordeel van FOBS is dat het je toestaat toe te slaan vanuit richtingen die met gewone ICBM's niet worden verwacht. Via een traject over de zuidpool bijvoorbeeld. Dan benader je de VS (het doelwit) vanuit het zuiden (gele lijn), terwijl
1/x A curious Navigational Warning has appeared for what appears to be a series of Space Debris deorbits.
The areas point to deorbit from a ~51-53 degree inclined set of orbits. #Starlink mass #deorbit?
Some areas line up with ISS passes in the two time windows given, but (cont.)
2/x (cont.) but AFAIK nothing will leave the ISS between now and August 10. And the areas south of Alaska do not line up with ISS groumndtracks in the given two time windows.
So my guess is multiple #Starlink deorbits (but I might be wrong).
The #Proton-M third stage from the #Nauka launch is now coming down faster and faster.
Current prediction models place reentry within 2 days from now, either late August 5 or early August 6, with the trend in predictions tending towards August 5. @SSC_NL
The #Proton-M third stage from the #Nauka launch now has less than one day left in orbit. Current model forecasts suggest a reentry in the morning of August 6 UT.
1/x Navigational Warnings have appeared for the @VirginOrbit "Tubular Bells part I" launch on June 30 (a LauncherOne rocket launched from the 'Cosmic Girl' aircraft).
This launch includes #BRIK-II, the first Dutch military satellite, launched for the Royal Netherlands Air Force.
2/x "BRIK-II" is a 6U cubesat (about 60 x 30 x 20 cm, 10 kg).
It is named after the very first aircraft, named 'Brik', of the RNLAF predecessor in 1913-1916. It is also the name for a brick, hence the mission patch

3/x The small experimental BRIK-II satellite includes equipment for communication, for monitoring "Space Weather", and for ELINT.
It was built by @isis_space
1/x Updated map, showing the trajectory of the Chinese #CZ5B rocket (blue lines) over the uncertainty interval in the latest TIP of CSpOC, the US military tracking network.
Within the 12 hr wide uncertainty window, it can fall anywhere on these blue lines.
2/x Also shown are cities with populations of 1 million or more in the relevant area between 41.5 N and 41.5 S
3/x The rocket is steadily coming down, last orbital determination has the highest point in the elliptical orbit (the so called apogee, blue) at about 218 km, the lowest point (perigee, red) at about 146 km.
1/x Update: de lichtblauwe lijnen tonen waar de Chinese CZ-5B raket mogelijk kan neerkomen: de lijn geeft het traject van de raket over het nog steeds 12 uur grote (!) onzekerheids-interval in tijdstip van de laatste TIP van CSpOC (het Amerikaanse militaire trackingnetwerk).
2/x het onzekerheidsinterval loopt van ongeveer 22u NL tijd op de 8e tot ongeveer 11u NL tijd op de 9e.
3/x Ondertussen komt de raket steeds sneller omlaag. De meeste recente baanbepaling heeft hem nu in een ellipsvormige baan met het hoogste punt (blauwe lijn) op ongeveer 218 km en het laagste punt (rode lijn) op ongeveer 146 km.
