China has picked up its launch cadence within the final two weeks as they proceed to push ahead in its bold 2023 launch schedule. Not solely did they launch three rockets from the Chang Zheng household in a brief time frame, but in addition Gushenxing-1 from Web site 95A at Jiuquan joined the combination with the “Lemon Tree” mission.
What’s extra, the nation outlined plans for its upcoming Chang’e-7 lunar mission. Whereas on the floor of the Moon, the Chang’e-7 lander is deliberate to drill into the lunar floor seeking water ice.
Gushenxing-1 | Lemon Tree
On July 22, at 05:07 UTC, a Gushenxing-1 rocket took flight from Jiuquan. The rocket carried two satellites to orbit, Qiankun-1 and Xingshidai-16, which had been later confirmed to be efficiently launched from the rocket. One of many satellites is supplied with ADASpaces blockchain expertise and is the world’s first satellite tv for pc to characteristic in-orbit visualized blockchain certificates.

This launch is a part of a big enhance in launch cadence for the Gushenxing-1 rocket, which is deliberate to launch six to eight occasions within the second half of 2023.
Chang Zheng 4C | Fengyun-3F
Fenguyen-3F took flight from the Jiuquan Satellite tv for pc Launch Heart at 3:47 UTC on Aug. 3 from Web site 9401 (SLS-2), and the mission was confirmed to be a hit. The car for this mission was the Chang Zheng 4C rocket.
The Fengyun (FY) satellites are a collection of climate satellites positioned in Solar-synchronous orbits (SSO). The satellite tv for pc for this mission weighs 2,250 kilograms and has an anticipated lifespan of 4 years. They function on a single photo voltaic panel and battery provide design.
The FY-3 satellites are polar-orbiting satellites that function in an 800-kilometer orbit, inclined at 98.8 levels. Utilizing ten totally different devices, this satellite tv for pc will be part of seven at the moment energetic satellites in orbit to observe totally different climate patterns and formations from area.
The rocket for this mission was the Chang Zheng 4C (CZ-4C), which is a part of the primary technology of China’s Chang Zheng launch autos. Its major objective is to launch medium-weight SSO satellites utilizing its three-stage design. This was the third flight of the CZ-4C this yr, after a Tianhui mission in March and one other mission in March that launched a couple of Yaogan satellites.

Chang Zheng 2D | Yaogan 36 Group 05
Yaogan 36 Group 5 launched on July 26 at 20:02 UTC from Launch Advanced 3 on the Xichang Satellite tv for pc Launch Heart in China. Yaogan 36 Group 5 is a gaggle of three satellites constructed for distant sensing functions. Like different Yaogan payloads, the mission’s precise use case and aim stay labeled.
The Yaogan satellites are navy reconnaissance spacecraft which might be constructed to serve a wide range of totally different roles whereas in orbit — often getting used to survey areas of land or reveal new technological developments. Whereas the earlier Yaogan 35 and 36 launch patches shaped a puzzle that resembled the ocean, which indicated that they is likely to be used for ocean surveillance, this launch’s patch began a brand new puzzle displaying bushes and flat land. This might imply that this new group of Yaogan satellites may very well be used for land surveillance.
Neither the load nor different technical particulars in regards to the satellites have been are revealed. The launch car for this mission was a Chang Zheng 2D, which has been used up to now for various Yaogan missions. It’s a very generally used rocket that has already seen six flights in 2023.

Chang Zheng 2D | Sixiang AS-01 to 03 & Lingxi-03
Sixiang AS 01-03 are three payloads constructed by Sixiang expertise and had been launched atop a Chang Zheng 2D at 02:50 UTC on July 22 from Launch Advanced 9 on the Taiyuan Satellite tv for pc Launch Heart. Of the three payloads, there may be an optical satellite tv for pc with a meter-level decision, a thermal infrared satellite tv for pc, and an artificial aperture radar (SAR) satellite tv for pc. These satellites have been designed to meet buyer requests for a lot of companies that work with Sixiang.
Sixiang needs to make sure that they’ll present imagery of wherever on Earth in 48 hours utilizing their SAR satellite tv for pc, ought to SAR imagery of that space be wanted. The wide-format optical satellite tv for pc can cowl as much as 100 kilometers of land in width, with a decision of 1 meter, and the thermal infrared satellite tv for pc has a variety of as much as 1000 kilometers.
The secondary payload for this mission is the Lingxi-03 flat aircraft LEO communication satellite tv for pc. In an analogous design to SpaceX’s Starlink, the satellite tv for pc is only a flat floor with a deployable photo voltaic panel and doesn’t have the attribute cubic satellite tv for pc form. This permits for various meeting and transportation of the satellite tv for pc when contained in the payload fairing, thus permitting for a rise within the quantity satellites launched on a mission.
New particulars on Chang’e-7 lunar mission
China just lately outlined new particulars and plans for its upcoming Chang’e 7 mission and the way the probe will dig for water on the Moon. In newly-revealed info, a mini-probe (doubtless a rover) shall be launched from the Chang’e-7 from an space that’s illuminated through daylight. The rover will then descend right into a crater that’s completely within the shadows. As soon as there, it would start to drill into the bottom to seek for potential water-ice samples.

After this, a mechanical arm will transfer the samples drilled by the rover into an onboard furnace to warmth and analyze the samples. This can then decide if water or ice is current within the samples. Chang’e 7 is without doubt one of the deliberate Chinese language moon missions and is at the moment focusing on a 2026 launch and touchdown.
