Jonathan's Space Report
No. 860 draft 2026 Sep 1 Bromley, UK
-----------------------------------------------------------------------------------------------------
Update:
-------
Construction on my new Space Library near London is sort-of-proceeding, with, alas, further delays.
Updates at https://www.gofundme.com/f/fund-jonathans-space-report-library-transition
ISS
----
Expedition 75 is underway.
On Sep 1 Adenot and Meir, in suits 3003 and 3015, carried out US EVA-99.
They replaced a planar retroreflector antenna on IDA-2, and replaced an EHDC camera at CP3.
They also installed some cables, obtained samples from the ISS exterior to test for
microorganisms, and performed some prep work for maintenance of the AMS experiment.
Depressurization to repressurization was 1231 to 1929 UTC.
Starlink Launches
------------------
Starlink Group 15-23 (27 Ku sats) was launched on Sep 2 by Falcon 9 from Vandenberg.
Zhisenxing-1
------------
The US Space Force did not catalog the Zhishenxing-1 (Pallas-1) test flight
and Galactic Energy have not released any orbital parameters so I regard success of the launch
as still subject to confirmation.
For the time being I am assigning it the 'uncataloged' designation 2026-U05.
Rocket Lab
----------
Rocket Lab Electron flight 94 placed Synspective's Strix-9 radar sat in orbit on Sep 2.
ISRO
-----
ISRO launched GSLV Mk II flight F17 on Sep 3, placing the GISAT-1A (EOS-05) imaging satellite in
subsynchronous transfer orbit.
