Jonathan's Space Report
No. 790 Draft 2021 Feb 28 Somerville, MA
---------------------------------------------------------------------------------------------
International Space Station
---------------------------
Expedition 64 continues under the command of Sergey Ryzhikov.
In addition to the satellites previously mentioned, NG-15 also delivered the
Japanese WARP-01 and Sanko (STARS-EC) cubesats for later Kibo deployment.
On Feb 28 astronauts Rubins and Glover carried out spacewalk EVA-71 to begin
installing solar array modification kits. They used EMUs 3015 and 3009, with
SAFER 13 and 18. The first mod kit was installed
on solar array mast canister 2B, on the P6 truss segment. Each 150 kg kit consists
of a truss consisting of three lower struts (left, middle, right) and
an `upper triangle' with a mounting bracket. The new IROSA solar arrays,
to be launched later this year, will be installed on the brackets.
The work went more slowly than expected. The 2B kit was completed but with
some issues with the bolts. The upper triangle for the 4B kit was assembled but
not installed; it was tied to the 4B IEA and the work is expected to be completed
during the next spacewalk. Airlock depressurization was at 1101 UTC with
hatch open at 1111 UTC; hatch was closed at 1811 UTC and the airlock began
repressurization at 1816 UTC. Rubins reported she had an ear blockage, so
the repress was slower than usual and passed the 50 mbar level I use to mark
EVA at 1818 UTC.
On Mar 5 Rubins and Noguchi completed the work with EVA-72, installing
the 4B mod kit on the 4B mast canister and tightening the bolts on the
2B kit. The airlock was depressurized from 1133 to 1836 UTC; the hatch
was open from 1336 to 1828 UTC.
YG-31
-----
The Yaogan 31 hao 03 zu (YG-31 Group 03) cluster of three signals
intelligence satellites was launched on Feb 24. YG-31 Group 01 was
launched in Apr 2018 and Group 02 was launched on Jan 29 this year.
PSLV-C51
--------
ISRO and New Space India Ltd launched a PSLV-DL from Satish Dhawan Space Centre
on Feb 28. The PS4 upper stage placed INPE/Brazil's 637 kg Amazonia-1 imaging satellite
in a 750 km orbit, and then made two burns to lower orbit to 511 km where
it deployed a set of small satellites:
Sindhu Netra is a 10 kg AIS (ship tracking) satellite built by PES University, Bengaluru for DRDO
SDsat (Satish Dhawan Sat) is a 4 kg satellite from Space Kidz India
Three 0.25U university cubesats which together comprise the UnitySat mission:
JITSat (Jeppiaar Inst of Technology, Sriperumbudur);
GHRCEsat (G.H. Raisoni College of Engineering, Nagpur);
Sri Shakthi Sat (Sri Shakthi Inst. of Engineering and Technology, Coimbatore).
SAI-1 Nanoconnect-2 is a 2U cubesat from UNAM (Mexico City); it will test a software-defined-radio
unit from Space AI Inc (San Francisco).
Spacebee 76 to 87 (serial numbers to be confirmed), 0.25U IoT comms satellites for Swarm Tech (US).
Arktika-M
----------
On Feb 28 Russia launched a Soyuz-2-1B from Baykonur with the first
Arktika-M weather satellite. The satellite will be placed in Molniya
orbit. In addition to weather imagers the 2200 kg satellite, using the
Lavochkin Navigator bus, also carries a search and rescue communications
relay payload.
Starlink
---------
60 more Starlinks were orbited on Mar 4 on mission V.10-17.
Errata
-------
In the previous issue I reported 36 SpaceBEE on Transporter 1 ESPA-port B2; there were only 24.
The other 12 SpaceBEEs on the launch were on ION-SVC, as noted further down in the list.
Also, the Dove satellites on port C1 are Flock 4s, not Flock 4c - sorry about that typo.
Progress MS-16 docked with Pirs on Feb 17, not Feb 16.
