Jonathan's Space Report
No. 858 draft 2026 Jul 1 Bromley, UK

Update:
-------
Construction on my new Space Library near London is finally proceeding.

Warning: TLE format expired (sort of)
--------------------------------------
Space Force use US satellite catalog numbers 70000 to 99999 as temporary
identifiers for not-yet-identified objects. When the US satellite
catalog hit 69999, it then rolled over to 100000, skipping the space
reserved for temporary IDs. At this point the venerable 80-character
punch-card-heritage TLE format stopped working (there is an ugly
'Alpha-5' hack to use letters in the catalog numbers to buy a another
year or so, but you should avoid it). It is time to make sure that your
orbit software that ingests Space Force data is upgraded to use a newer
format - I recommend the JSON one.
The Alpha-5 hack is that the string A1744 in the catalog number
field of a TLE is to be interpreted as 101744, F2317 is to be interpreted
as 152317, and so on. Note that `A1744' is *not* the catalog number, and you
should not quote it as such - if you must use Alpha-5 data do the mapping
at I/O time and use the numerical catalog number elsewhere.
In the JSON GP data from Space-Track, the Alpha-5 hack is not used, the full
greater-than-100k catalog numerical catalog number is written explicitly.
ISS
----
Expedition 74 continues.
Progress MS-34 reboosted the ISS orbit with a 568s, 1.1m/s burn at 2039 UTC Jul 1.
On Jul 2 the Kibo RMS extracted NRCSD-30 from the JEM airlock, and the
NRCSD ejected six university cubesats: Proves-Alcyone (Columbia) and
Proves-Atlas (Northeastern) at 0850 UTC; HUCSat (Harvard) at 0900 UTC;
Coconut (ASU) and LeopardSat (Cincinnati) at 1030 UTC; Proves-Electra
(Santa Cruz) at 1140 UTC. (these deployment times are not yet confirmed).
Megaconstellation launches
--------------------------
Starlink Group 17-46 (24 Ku sats) was launched on Jul 2 by Falcon 9 from Vandenberg
Amazon Leo LA08 (29 sats) was launched on Jul 2 from Canaveral on ULA Atlas V 551 flight AV-114.
Starlink Group 10-50 (29 Ku sats) was launched on Jul 5 by Falcon 9 from Canaveral.
Starlink Group 10-42 (29 Ku sats) was launched on Jul 9 by Falcon 9 from Canaveral.
Transporter 17
---------------
On Jul 7 the Transporter 17 rideshare mission was launched by Falcon 9 from Vandenberg.
After deploying rideshare payloads in a 600 km orbit, the Korean CAS500-4 was delivered to a 900 km orbit.
The rideshare payloads were:
Imaging: Cuby 1 to 5 (Germany), TOM-1 to 3 (Germany), N2-P-BODY (US), CloudCT-Precursor (Israel),
Balkan-3 (Bulgaria), Hyperion GR1 (Greece), Posidonia (Balaeric Islands),

Radar: ICEYE x 4 (Finland)
Remote sensing/Climate: GHGSat-C-16 and 17 (Canada)
Space weather: SENTINEL 1 (Germany), SCION-X (Taiwan), MAVERIC (US)
Tritium battery test: Bohr (US)
Military prox ops tests: SPEAR-1A/B/C (US), Flashpoint-1,2 (US)
Technology and student experiments: SUCHAI-4 (Chile), KOYO (Taiwan), Cybercube (ESA), Marmotsat (Canada),
Kostka (Czechia), Marina (Slovakia), Replicator-2 (Poland) R5-S9 (US)
Comms: IPOS (US), Centauri 9 (Australia), FossaSat 2E-26 (Spain), Kita x 2 (US)
Comms/GNSS-RO: Lemur-2 x 5 (US?)
RF monitoring: Deloitte 4 to 6 (US), BRO-31 (France)
Navigation: Leonav (UAE), ET-01 (US), RAFS Cubesat (Turkey)
Astronomy: GRITSS (US)
Hosted payload buses and tugs: Oasis-Alpha (Austria); ION SCV-023 (Italy), Nova-1 (US)
Navigator (US), LA3 (US)
SAST launches
--------------
On Jul 1 SAST launched a CZ-4B with the HY2-05 oceanographic satellite to a 937 x 958 km sun sync orbit.
At about 0018 UTC Jul 2 the CZ-4B upper stage made a perigee lowering burn to 649 x 934 km.
On Jul 4 SAST/CGWIC launched a CZ-6A with the Group 13 cluster of Qianfan internet satellites.
CALT launches
--------------
On Jul 5 CALT/CASC Commercial Rocket launched an upgraded CZ-8A from Hainan with twenty Qianfan satellites (Group 15).
On Jul 10 CALT launched the first CZ-10B from Hainan, placing a test payload, SECM's CX-26, in orbit.
The CZ-10B kerolox first stage successfully landed on a downrange barge equipped with a tower containing
an arrestor cable net. The second stage of CZ-10B is methalox, making this the first methane/kerosene combination
vehicle to reach orbit.
LINK
-----
On Jul 3 the L-1011 Stargazer aircraft N140SC took off from Kwajalein runway 06/24 at 0739 UTC
and at 0836 UTC dropped its cargo, a Northrop Grumman Pegasus rocket, over about 166W 7N.
The three-stage Pegasus delivered the 430 kg NASA/Katalyst Space LINK spacecraft to low orbit.
LINK's mission is to rendezvous and dock with NASA's SWIFT space observatory and boost it
to a higher orbit.
Asteroids
---------
On Jul 4 China's Tianwen-2 probe matched orbit with (469219) Kamo'oelawa at a distance of about
20 km, in preparation for a sample return attempt.
On Jul 5 at 0930 UTC Japan's Hayabusa-2 flew past (98943) Torifune at a distance of about 1 km.
