chang'e 5

The Lander will make one continuous landing burn using its main engine that actively throttles down as part of the descent.

Chang’e 5-T1 uses a circumlunar free return trajectory which in theory is created only by the gravitation in a two-body system and does not require propulsion, although in practice, course corrections are needed to optimize the trajectory. Chang'e 4 (to launch around 2020) was the engineering backup to the Chang'e 3 lander. According to an article from the China News Network, the Chang'e 5 test vehicle performed the imaging campaign between August 30 and September 2 from an altitude of 30 kilometers above the lunar nearside. A central interface from the lander to the Ascent Vehicle is attached at the top of the vehicle using an arm that can be moved to the side to clear the way for the vehicle to launch from the top deck of the lander. Once out of the atmosphere, the vehicle will be on a ballistic sub-orbital trajectory with an apogee near 140 Kilometers. The system will operate a one-minute sequence that is repeated five consecutive times to increase the probability of reception due to uncertainties in third stage rotation. The rover Yutu 2 is already doing its first meters on the lunar regolith. The second burn of the 3rd stage will be just over three minutes in duration to put the vehicle on a trans-lunar trajectory with an insertion velocity of 10.9km/s. Be a Planetary Defender and join our mission to defend Earth. The upper stage of the Long March makes its closest approach 102.56 hours after launch. The mission goal is to land in the Mons Rumker region of Oceanus Procellarum (roughly 41-45 deg. The hints seen in the previous Chang’e missions indicate that China is aiming to be ready to initiate development for human missions to the Moon with plenty of prior knowledge should that path be chosen over the coming years. The cameras, spectrometer, radar and radiation detector will be able to improve our knowledge of this very ancient region of the Moon. DFH-3 has a dry mass of approximately 1,150 Kilograms and is capable of carrying up to 1,300 Kilograms of propellant. On Launch Day, the Long March 3C/E goes through a seven-hour countdown procedure that includes extensive launch vehicle checkouts and the cryogenic tanking sequence. [3][13], The estimated launch mass is 3,780 kg (8,330 lb), the lander is projected to be 1,200 kg (2,600 lb) and the ascent vehicle is about 120 kg (260 lb). These are geographical points where sunlight shines almost continuously. First the relay satellite in June, then the lander carrying the rover at the end of the year. These are called peaks of eternal light. The capsule also has a series of thrusters to control its attitude in space and during atmospheric entry.

A Unified S-Band terminal is used for command uplink and housekeeping data downlink achieving low data rates of 1024bit/s for telemetry transmission and 125bit/s for command uplink. The Service Module would be in charge of placing the stack into a circular orbit around the Moon at an altitude 200km (it is likely that a polar orbit will be used, similar to Chang’e 3). The docking is accomplished using a claw-type docking mechanism. Its main objective would be to establish a robotic lunar station on the south pole of the Moon. The return flight will again take approximately four days and could include more trajectory correction maneuvers to fine-tune the return path of the vehicle and precisely target the re-entry corridor chosen for the mission. In that orbit, the Lander – Ascent Vehicle stack will separate from the Service Module in a one-time separation event likely using pyrotechnics. The content of the Chang’e 8 mission is still unclear. The spacecraft is equipped with a bipropellant propulsion system using Monomethylhydrazine fuel and MON-1 (Mixed Oxides of Nitrogen) oxidizer. In that orbit, the Lander – Ascent Vehicle stack will separate from the Service Module in a one-time separation event likely using pyrotechnics. It has been compared to a similar device on Earth. Just after passing the T+4-minute mark, the launcher will jettison the protective payload fairing, exposing the Chang’e 5-T1 spacecraft for the rest of its journey. The South Pole does not interest only China. N, … In the more distant future, China has the ambition to take its taikonauts on the moon with its giant rocket Long March 9, which development is expected to end around 2030.

The end effector of the arm includes a scoop for the acquisition of samples, a sample processing system using vibration and separation mechanisms that ensure that several individual samples can be acquired without coming in contact with each other. Instead, the vehicle will be carrying a number of samples on a journey beyond Earth orbit to learn about the effects of the BEO environment on various organisms, seeds, plants and other samples. This summer the Chinese space agency has been making progress toward its planned 2017 launch of the Chang'e 5 robotic sample return mission, performing low-altitude imaging of the future landing site. Specifically, the container will contain potatoes, seeds of the plant Arabidopsis, and eggs of silkworms.
