It seems that ever since they put Zhurong Mars rover in sleep mode last May,they can not wake it up now,unable to establish connection with it
It sounds like the sandstorm might have damaged some components or the solar panel on the Rover. NASA also had one of their Mars Rovers broken by the same type of problem.

China focusing on reusable rockets: Long March-5 chief designer

With the in-orbit transposition of the Mengtian lab module, the China Space Station formed its basic T-shape configuration in November 2022.

All three modules of the space station – core module Tianhe and lab modules Wentian and Mengtian – were launched atop Long March-5B carrier rockets.

Behind this achievement is 16 years of work by the research team since the project obtained approval in 2006. The team made 247 breakthroughs in key technologies in the preliminary development stage.

The Long March-5 rockets have seen nine missions since the maiden flight in 2016, including five by the Long March-5 rockets and four by the Long March-5B rockets.

Li Dong, chief designer of the Long March-5 rocket at the China Academy of Launch Vehicle Technology under the China Aerospace Science and Technology Corporation, said that the Long March-5 rocket is used for launching spacecraft to high-Earth orbit – with a perigee of about 200 kilometers and an apogee of 36,000 kilometers – and for deep-space exploration, such as the Mars probe.

As a variant of the Long March-5, the Long March-5B has one less core stage and is designed to launch spacecraft into low-Earth orbit, with a perigee of 200 to 400 kilometers, Li added.

Li said that a technological breakthrough in terms of compatibility made it possible for the two large rockets to be produced in the same course of development and planning, improving the country's ability to enter both high- and low-Earth orbits while saving research and development expenditure and time.

China will continue to improve the capacity of its rockets in the future, Li said.

Now, the cost of getting rockets into space is high, so research on reusable rockets is needed for easier, cheaper and more frequent visits to space, Li said, adding that China will develop reusable rockets and achieve breakthrough in reusable space vehicles.

According CASC's

channel, China will develop an improved variant of CZ-7A capable of carrying heavier payloads, with an enlarged payload fairing diameter of 5.2m. Production of CZ-7A will also be stepped up, from the current rate of 4-6 per year to 8-10 by 2025.
【发射大重量高轨卫星!我国将研制改进型长七A火箭】为适应未来卫星重量进一步增加的趋势,长七A火箭团队还将通过替换三子级的方式,研制出能够适配5.2米直径整流罩的改进型火箭,进一步提升长七A火箭的综合性能。不仅如此,试验队还将持续提升长七A火箭产能。目前我航一院每年可生产4~6发长七A火箭,预计2025年可达到每年8~10发

This dovetails with an earlier paper published on the future of CZ-7A, which states a requirement of launching payloads greater than 6200kg, an enlarged fairing diameter of 5.2m from the current 4.2m, with the YF-25D replacing the current YF-25 in the final stage.

Some images from the first launch of 2023. A CZ-7A successfully inserted the Shijian-23 (实践二十三号) satellite into orbit. This marks the 459th launch of the Long March series of carrier rockets. The Shijian-23 satellite was developed by the 8th Academy of CASC, and it's used to carry out certain scientific experiments and technical verification.
