Title: TJSW-6 - CZ-3B/G2 (Y77) - Xichang, LC3 - February 4, 2021 (15:36 UTC)
Post by: zubenelgenubi on 01/19/2021 05:21 pm
Cross-post:
Several local tour operators are currently advertising (https://9ifly.spacety.com/forum.php?mod=redirect&goto=findpost&ptid=94084&pid=794250&fromuid=19646) for a LM-3B Xichang launch on January 19, curiously stating that it's of a Tianhui series satellite. That's highly interesting because the series of cartography satellites doesn't seems likely to involve BLEO operations.
Either the tour operators got it wrong, or there's another LM-3B SSO launch soon, or (one theory from Chinese forums) it's the long rumored/reported Chinese geosynchronous SAR satellite. (note that SAR requires the antenna to be moving to work, so geostationary orbit won't work and people assume it would go to an inclined GSO)

As of 15 January:
"According to travel agency news, the mission was postponed to launch on 2021.2.5." (5 February)

Tiantong-1 (03) successfully launched, as scheduled, on January 19.

The annual family holiday season accompanies and follows Chinese New Year.  That holiday falls this year on February 12.

And two more.

Payload unknown, but possibly a Tianhui GEOSAR satellite.

According to a post on 9ifly Chinese space forum, the rocket to be used os a CZ-3B/G3 with serial number Y77 and the payload is the 20-meter L-band SAR Tianhui-3 satellite to operate in GEO.

Actually this isn’t quite settled down yet, the mystery deepens with launch day mail covers (a traditional memorial collectible) issued lately include BOTH a mail cover for the launch of TJSW-6 AND tracking of the launch of Tianhui-3 from the Yuan Wang tracking ships.

These usually only pop up days before launch. Maybe TJSW-6 is a cover name of Tianhui-3 or something?  :-\

Could there be two satellites?  One larger satellite and another, smaller, yet also important satellite?

SAST was reported as the satellite manufacturer, which most likely rules out the GEO SAR theory for this one (it's apparently by CAST) & matches w/ this being yet another of the TJSW(2 and 5) early warning satellites built by them.

According to reports TJSW-6 seems to be yet another satellite that was impacted by the Antonov An-124 grounding earlier last year, with it ultimately transported in 2 parts (satellite platform and payload) by road and rail respectively after the original planned rail route was down for repairs as well.

I wonder why there is a 3 on it. I see four hypotheses:
- It's Tiantong-1 n°03 patch, that he didn't change between the two flights.
- It's the patch of the mysterious Tianhui-3 that might fly soon.
- This is a reference to the Huoyan-1 program, TJSW might be the third satellite according to some rumors (https://space.skyrocket.de/doc_sdat/tjs-2.htm).
- It has another meaning, or it's just random.

Chinese Rendezvous in GEO?
Heads up to any observers with visibility of GEO at 180° longitude.
Chinese TJS-5 (47613/2021-010A) and TJS-6 (44978/2020-002A) satellites came within 60 km of each other Mar 5 at around 20:00 UTC. Minor differences in inclination and eccentricity are causing them to oscillate up to about 600 km apart but to all intents and purposes they have made rendezvous.

Objects that landed in Chandrapur most likely Chinese rocket debris

Bengaluru/Chandrapur: The blazing light trail observed in parts of Vidarbha, and also by some people in Gujarat and Madhya Pradesh, on Saturday night may have been caused by a Chinese rocket body debris. Two metallic objects landed in Ladbori and Pavanpar villages in Sindewahi tehsil in Chandrapur district, triggering panic among the villagers.

Chandrapur district collector Ajay Gulhane said that the state disaster management authority has been asked to take custody of both the objects.

Quote
A metal ring of around 10x10 feet circumference landed in Ladbori village at around 7.45pm on Saturday. “We were preparing a community feast, when the sky blazed with the red disk which fell with a bang on an open plot in the village. People ran to their home fearing explosion and remained inside for nearly half an hour,” said a woman.

Quote
“The other piece, a large metallic ball, fell in a dried pond near Pavanpar village at the same time. Villagers brought the ball weighing around 10kg to the village.”

According to Chopne, the metallic sphere appears to be a device containing hydrogen fuel used in booster rockets for satellite launch.

Quote
“The CZ-3B was originally predicted to have a re-entry time of 4.37pm IST and impact location close to Myanmar. Post event, USSPACECOM put the re-entry time as 7.42pm IST with impact location as Arabian Sea. With the latest orbital information from USSPACECOM, the closest match to the observed re-entry over India has to be from Chinese CZ-3B, which was launched on February 4 last year,” a senior Isro official said.

Inputs from several sources are received on the mysterious flashing light seen in the sky during the evening hours on April 2, 2022, in Maharashtra and Madhya Pradesh. Formal communication has been received from the office of the district magistrate and district collector of Chandrapur, Maharashtra. It is reported that a metal ring and a cylinder-like object or found in an open field in Pawanpur village. As requested by the district administration, a team of scientists from ISRO is visiting Pawanpur for inspection and further scientific inquiry.

2 ISRO scientists visit Sindewahi

TWO officials of the Indian Space Research Organisation (ISRO), Thirvanantapuram, on Friday, visited Sindewahi Police Station to inspect the objects that had fallen from the sky at Pawanpar village and other parts of Sindewahi and Brahmapuri tehsils recently. Parts of SLV including a metal ring and six cylinders were found at different places in Sindewahi and Brahmapuri.

Two cylinders were found in Pawanpar and Maregaon villages on April 3 while two more cylinders found at Gunjawahi (Kotha)and Asolamendha pond areas on April 4. The cylinders weighed around 6.839 kgs and bore the same number (3CCA301001 B) on them, informed sources. Meanwhile, two more cylinder (6.839kgs) and (2.865kgs) were later found at Bodra and Shelda in Brahmapuri tehsil.

India’s space agency is examining a large metal ring and a cylinder-like object that fell into rural western India April 2, with a preliminary investigation suggesting they could be parts of a Chinese space rocket’s upper stage that reentered the atmosphere that day.

Two scientists from the Indian Space Research Organisation (ISRO) conducted the onsite investigation in Sindewahi on April 15. They tentatively labeled the objects as parts of a Chinese Long March rocket, according to local reports. A formal investigation is underway.

The metal ring is reportedly two to three meters in diameter and weighs more than 40 kilograms. The cylinder-like object is about a half meter in diameter.

Space-watcher Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics tweeted April 4 that the ring was consistent with a piece of China’s Long March 3B rocket. In another tweet,McDowell said the crashed objects could be parts of the third stage of Long March 3B serial number Y77, which was launched in February 2021. China remains silent on the reentry incident.

Seems to be a mission patch.

I wonder why there is a 3 on it. I see four hypotheses:
- It's Tiantong-1 n°03 patch, that he didn't change between the two flights.
- It's the patch of the mysterious Tianhui-3 that might fly soon.
- This is a reference to the Huoyan-1 program, TJSW might be the third satellite according to some rumors (https://space.skyrocket.de/doc_sdat/tjs-2.htm).
- It has another meaning, or it's just random.
