The combination of Chinas Tianzhou-9 cargo spacecraft and a Long March-7 Y10 provider rocket was transported vertically to the launch pad at the Wenchang Spacecraft Launch Site in south Chinas Hainan Province on Saturday, according to the China Manned Space Agency.All the facilities and devices at the launch site are in good condition.
Numerous pre-launch function checks and joint tests will be carried out as prepared, and the freight spacecraft will be introduced in the near future at a suitable time.Rocket powering space freight missionUsing kerosene and liquid oxygen as propellants, the Long March-7 rocket is Chinas brand-new generation of medium-sized launch car, understood for its high reliability, boosted safety and eco-friendly design.
Bundled with 4 boosters, the rocket stands 53.1 meters tall and has a size of 3.35 meters.It has a low-Earth orbit payload capacity of 14 tonnes, which matches the mass requirements for the Tianzhou freight spacecraft to deliver products to the space station, said Wang Xi at the China Aerospace Science and Technology Corporation (CASC).
The rocket series has successfully sent out the Tianzhou-1 through to Tianzhou-8 cargo spacecraft into the established orbit.To satisfy the emergency situation launch requirements of Chinas crewed spaceflight program, a backup rocket is prepared.
If the space station comes across an urgent scenario, this backup rocket can be launched within three months, said Guo Jiarui at the CASC.The Long March-7 rocket is likewise efficient in dynamically recalculating its optimum flight path, just comparable to how contemporary navigation applications change routes based on live traffic.
This permits the rocket to continually update its trajectory based on present position and target orbit, guaranteeing an orbital insertion precision within four seconds.Whats aboard the space reveal? Tianzhou-9 is the fourth cargo spacecraft in the application and development stage of Chinas space station.It will take about 6.5 tonnes of supply materials, consisting of consumables, propellants and application speculative devices, to support the in-orbit life and working of Chinas Shenzhou-20 and Shenzhou-21 taikonauts.Particularly, 2 sets of locally developed spacesuits will be launched this time.
These brand brand-new spacesuits include an extended functional lifespan, from 3 years of 15 spacewalks formerly to 4 years of 20 spacewalks.Tianzhou-9 will likewise bring a set of core muscle training device to more upgrade the space stations gym, which will help taikonauts counteract muscle atrophy in microgravity.Two sets of cutting-edge area science speculative equipment will be brought as well.
