International Space Station
---------------------------
On Apr 5 at 1030 UTC the Dragon spaceship Resilience undocked from the IDA-2/PMA-2 docking
port on the ISS Harmony module, backed off 60 metres, and redocked with the IDA-3/PMA-3
port on the same module's zenith side.
On Apr 9 at 0742 UTC the Soyuz MS-18 spaceship was launched from Baykonur carrying Oleg Novitskiy,
Pyotr Dubrov and Mark Vande Hei. It docked with the ISS Rassvet module at 1105:06 UTC the same day.
On Apr 17 at 0134 UTC Soyuz MS-17 undocked from the Poisk module with astronauts Ryzhikov, Kud-Sverchkov
and Rubins. After a deorbit burn at 0401 UTC the descent module landed in Kazakhstan at 0455 UTC.
Expedition 65, under the command of Shannon Walker, formally began when Soyuz MS-17 undocked.
As of Apr 22 the ISS visiting vehicle list was:
Zvezda aft: Progress MS-14
Pirs: Progress MS-16
Poisk: -
Rassvet: Soyuz MS-18
IDA-2/PMA-2: -
IDA-3/PMA-3: Dragon C207 (Resilience)
Unity nadir: Cygnus NG-15 (S.S. Katherine Johnson)
Harmony nadir: -
OneWeb
------
On 2021 Mar 25 Starsem launched a Soyuz-2-1b from the Russian eastern launch site of Vostochniy,
placing the fifth set of OneWeb satellites in a 433 x 445 km x 87.4 deg parking orbit.
Gao Fen 12-02
-------------
On Mar 30 China's SAST launched a CZ-4C placing the second GF-12 radar satellite in orbit.
Unisat-7
--------
The Gauss srl Unisat-7 host satellite released its tiny payloads on Mar 25.
Shiyan 9
--------
China made the second launch of the CZ-7A on Mar 11, following a launch failure on the first such mission.
The payload, Shiyan 9, was placed in geotransfer orbit. It seems likely that this is a test mission
intended to remain in that orbit, perhaps making radiation measurements, and no
apogee burn to geonsynchronous orbit was planned. (This item was inadvertently omitted from JSR 790).
Shiyan 6
--------
The third Shiyan 6 satellite was launched on Apr 8 from Taiyuan. The satellite went to a higher
orbit than the two previous Shiyan 6 missions. The purpose of the missions is unclear.
Electron 19
-----------
Rocket Lab's Electron mission 19 was launched from Mahia on Mar 22 placing in orbit several small satellites:
BlackSky Global 9 (also called BlackSky 7), a 55 kg imaging sat
RAAF M2 A and B, a pair of 0.2 x 0.2 x 0.3m satellites for the Royal Australian Air Force
with AIS payloads and formation flying tests. The satellites were deployed attached and
will separate later.
Myriota 7, a 3U cubesat for IoT data relay for Myriota (Australia). Also called Tyvak-0152.
Centauri 3, a 6U cubesat for IoT data relay for Fleet (Australia). Also called Tyvak-0210.
Veery Hatchling v0.2, a 1U test satellite for Care Weather Technologies (US)
Gunsmoke-J, a communications satellite for the US Army SMDC; a similar sat is awaiting deployment from ISS.
The Electron kick stage also carries the Photon Pathstone payload with test components for the planned Capstone mission.
Starlink
---------
Starlink mission V1.0-L23 flew from Canaveral on Apr 7, with 60 more satellites. The first
stage landed on the OCISLY.
I have a new web page with detailed statistics and orbit histories for the Starlink satellites:
https://planet4589.org/space/stats/star/starstats.html
MEV-2
-----
The Space Logistics Services/Northrop Grumman MEV-2 satellite docked with the Intelsat 10-02 satellite at 1734 UTC
on Apr 12. The docked satellites are in GEO at 1.0W; MEV-2 will provide orbit control to extend IS 10-02's useful
life.
Reentries
---------
The Falcon 9 second stage from the Mar 4 Starlink mission, mentioned in JSR 790, reentered
over Oregon and Washington on Mar 26 at 0400 UTC. It was widely observed from the US Pacific Northwest
and the Vancouver area, and a COPV pressure vessel was found largely intact in eastern Washington state.
Ingenuity
---------
The Ingenuity Mars Helicopter made its first flight at about 0734:19 UTC
on Apr 19. It took off from the newly named Wright Brothers Field
(77.45102 E, 18.44486N in Jezero Crater, Mars; ICAO designator JZRO) and
reached 3 metres altitude before landing at the same spot 38 seconds
later.
Errata
------
In JSR 790, the EVA-72 hatch opening time should have read 1136 UTC, not 1336 UTC.
Note that Hirogari is another name for OPUSAT-II.
