On 20 april, at 1941 hours, the long march 7 remote 2nd carrier rocket, carrying the cargo ship skyboat i, set fire to the japanese space launch site in chinanan for about 10 minutes, and the ship was successfully separated from the rocket and entered its intended orbit and launched successfully。
Skyboat i, which will carry over six tons of material and equipment to space, can be said to be the largest and most heavy manned spacecraft in our country to date。
After the successful launch of the ship skyboat i, it will enter an orbit at an altitude of approximately 380 km and, once in orbit, will be connected to the orbited sky palace ii space laboratory。
This time skyboat i not only completed three on-orbit retrofitting of propellants, but also undertook the mission of an environmental ambassador, which, unlike the fate of the past, had burned down in the atmosphere, would land in the designated waters。
For satellites in general, when the mission is completed, it is accompanied by the exhaustion of propellant combustion, which slows down the orbit. After entering the atmosphere, self-burning is completed, which results in some amount in space debris and atmospheric pollution. For the first time, sky one entered a designated sea area by deorbiting itself, avoiding becoming space debris or derailing. It had made an outstanding contribution to the cause of space and its value in environmental protection was transcendent。
