[Congratulate! Chang'e-5 ascender perform controlled impact on the moon]

At 6:59 on December 8, the Chang'e-5 ascender was de-orbited in accordance with ground instructions. It impact the moon around 7:30, at designated drop zone near 0 degrees longitude and 30 degrees south latitude. Experts said that the Chang'e-5 ascender has successfully completed its mission, and the controlled de-orbiting and impact on the moon can prevent it from becoming space junk and avoid affecting the subsequent lunar exploration missions of international community. This is China's important role in its commitment to the peaceful exploration and use of space for mankind as a responsible power. (People's Daily)

CAS broke with tradition for one of the new missions, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM). It fast-tracked selection and development to take advantage of a new scientific opportunity, which Xiong Shaolin, an astrophysicist at CAS's Institute of High Energy Physics in Beijing, and his colleagues identified a month after the U.S. Laser Interferometer Gravitational-Wave Observatory announced its historic detection of gravitational waves in February 2016. They proposed putting two satellites into orbit on opposite sides of Earth that together could watch the entire sky for gamma rays emanating from the events that generate gravitational waves. Funding for technical studies arrived a few months later, and the mission has jumped to the front of the launch queue, with a date of 2020. "When you have this kind of opportunity you can't handle it like a normal mission, with selection and review taking 10 or 20 years," Xiong says.

XICHANG, Dec. 10 (Xinhua) -- China sent two satellites for the detection of gravitational waves into planned orbit from the Xichang Satellite Launch Center in Sichuan Province on Thursday morning.

The two satellites, which compose the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission, were launched by a Long March-11 carrier rocket at 4:14 a.m. (Beijing Time), according to the center.

Thursday's launch was the 355th mission of the Long March rocket series.

The GECAM satellites will be used to monitor high-energy celestial phenomena such as gravitational wave gamma-ray bursts, high-energy radiation of fast radio bursts, special gamma-ray bursts and magnetar bursts, and to study neutron stars, black holes and other compact objects and their merger processes.

In addition, they will also detect high-energy radiation phenomena in space, such as solar flares, Earth gamma flashes and Earth electron beams, providing observation data for scientists.

The GECAM project is carried out by the Chinese Academy of Sciences. The Long March-11 rocket is developed by the China Aerospace Science and Technology Corporation.

[Waiting for you to come home [love you] Chang'e-5 implements the first maneuver for lunar-earth transfer]

At 9:54 on December 12, the Chang'e-5 orbiter and returner combination after about 6 days of waiting around the moon, had implemented the first maneuver for lunar-earth transfer, from a near circular orbit to an elliptical orbit with perilune of about 200 kilometers near the moon. Later, the orbiter and returner assembly carrying the lunar sample will choose an opportunity to implement the second maneuver for Trans-Earth Injection, so as to get away from the lunar gravitational pull, enter the lunar-earth transfer orbit and return to earth.

[Chang'e-5 orbiter and returner combination carried out second lunar-to-earth transfer maneuver]

At 9:51 on December 13, Beijing time, the Chang'e-5 orbiter and returner combination carried out the second lunar-to-earth transfer maneuver, four 150N engines were successfully ignited at a distance of about 230 kilometers from the lunar surface. After about 22 minutes, the engines shut down normally. According to the monitoring and assessment of real-time telemetry data, the orbiter and returner combination successfully escaped lunar gravity into the lunar-earth transfer orbit.

Later, the Chang'e-5 orbiter and returner assembly carrying lunar samples will undergo midway orbit correction during the lunar-to-earth transfer process, and the separation of the orbiter and the returner will be carried out when appropriate.

Chang'e-5 completes first orbital correction en route to Earth

BEIJING, Dec. 14 (Xinhua) -- China's Chang'e-5 probe on Monday completed its first orbital correction en route to Earth, according to the China National Space Administration (CNSA).

The orbital correction was conducted at 11:13 a.m. (Beijing Time) when the two 25N engines on the orbiter-returner combination were operational for about 28 seconds.

The CNSA said all systems on the orbiter-returner combination that carries lunar samples are currently in good condition.

The orbiter-returner combination entered the moon-Earth transfer orbit on Sunday.

When the time is right, the orbiter and returner will separate from one another, according to the CNSA. The probe's returner is expected to land at the Siziwang Banner in north China's Inner Mongolia Autonomous Region in mid-December.

Chang'e-5 is one of the most complicated and challenging missions in China's aerospace history. It is also the world's first moon-sample mission in more than 40 years.

The probe, comprising an orbiter, a lander, an ascender and a returner, was launched on Nov. 24, and its lander-ascender combination touched down on the north of the Mons Rumker in Oceanus Procellarum, also known as the Ocean of Storms, on the near side of the moon on Dec. 1.
