Jonathan's Space Report

No 791 2021 Apr 20 Somerville, MA

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
