ISS
----
Expedition 73 continues.
On Oct 26 JAXA launched the HTV-X1 cargo ship. HTV-X is a second generation Japanese ISS cargo
ship. Launch mass about 16000 kg
of which the SM was 3800 kg, the PM 3800 kg, press cargo 4000 kg, external cargo 2000 kg,
consumables 2400 kg. Size is 8.0m long 4.4m dia with 18.2m solar panel span.
It consists of a pressurized module with CBM port, a service module (built at MELCO/Kanagawa)
with an IHI-built MMH/NTO propulsion system using twelve 120N HBT-1 thrusters, and
an exposed cargo section.
HTV-X1's exposed cargo section carries the i-SEEP-3B device that will be installed on the
Kibo EFU at EFU5; and the DELIGHT deployable structure test which will be activated after
ISS departure. HTV-X1 also carries an H-SSOD cubesat deployer carrying the 6U Tenkoh-2 cubesat
for Nihon Univ.
Inside HTV-X's pressurized section are cargo bags including a J-SSOD cubesat deployer
to be transferred to the Kibo module, carrying Gxiba-1 (UPAEP Mexico), UiTMSat-2 (UITM, Malaysia),
CORAL (Sapienza, Italy), Knacskat 2 (KMUT, Thailand), LEOPARD (Kyutech), and HMUSAT2 (Hokkaido U of Sci.).
HTV-X1 arrived at ISS on Oct 29, with rendezvous at 250 m distance at
1320 UTC. After some manuevering evaluations, the Canadarm-2 grappled
the HTV at 1558 UTC. Berthing at Harmony nadir was complete by 1850 UTC.
On Oct 28 astronauts Ryzhikov and Zubritskiy, in spacesuits Orlan MKS-7
and MKS-6, made spacewalk VKD-65 from the Poisk airlock on Oct 28, with
hatch open from 1418:01 to 2112:28 UTC and depressurization from 1357 to 2115
UTC. Among other activities they installed the IPI-500 experiment on
the Nauka module.
Chinese Space Station
---------------------
The CSS made a 3.2m/s orbit reboost on Oct 17 at about 0947 UTC, probably using the engines
on the Tianzhou-9 freighter.
Starlink launches
------------------
Starlink Group 10-17 (28 Ku sats) was launched on Oct 19 from Canaveral.
Starlink Group 11-19 (28 Ku sats) was launched on Oct 19 from Vandenberg.
Starlink Group 11-5 (28 Ku sats) was launched on Oct 22 from Vandenberg.
Starlink Group 11-12 (28 Ku sats) was launched on Oct 25 from Vandenberg.
Starlink Group 10-21 (28 Ku sats) was launched on Oct 26 from Canaveral.
Starlink Group 11-21 (28 Ku sats) was launched on Oct 28 from Vandenberg.
Starlink Group 10-37 (29 Ku sats) was launched on Oct 29 from Canaveral.
Other Falcon 9 launches
-----------------------
On Oct 24 SpaceX launched a Falcon 9 with the Spainsat NG-II military communications satellite
for Hisdesat. The 6100 kg satellite is an Airbus Eurostar NEO.
Chinese commercial launches
----------------------------
Zhongke Tansuo Jishu (CAS Space) launched a Lijian-1 from Jiuquan on Oct 19 with
a Pakistani hyperspectral satellite and two Zhongke AIRSAT radar satellites,
one purchased by Malaysian company TerraXpace. The satellites were placed in 1000 LTDN SSO.
CAST launches
--------------
On Oct 23 CAST launched a CZ-5 from Wenchang with Tongxin Jishu Shiyan 20 weixing (TJS 20),
likely a GEO sigint payload similar to TJS 11.
On Oct 26 CAST launched a CZ-3B from Xichang with Gao Fen 14 hao 02 xing (GF14-02), a
stereo topographic mapping satellite. Its sibling GF14-01 was launched on 2020 Dec 6 to the same
1030 LTDN orbital plane.
USSF-51
-------
Another secret subsatellite, USA 567, was released by one of the USSF-51 payloads in GEO drift orbit
in late October.
SDA T1TL-C
----------
The SDA T1TL-C satellites launched on Oct 14 have been designated in Space-Track as SDA-1664 to SDA-1684.
