China's National Space Administration (CNSA) announced on Friday that the Queqiao-2 satellite has successfully concluded its in-orbit communication tests, with both its platform and payloads operating as expected. CNSA affirmed that Queqiao-2's functions and performance align with mission specifications, enabling it to deliver relay communication services for the fourth phase of China's lunar exploration endeavour and forthcoming lunar missions undertaken by China and other nations. This milestone marks the Queqiao-2 mission as a resounding success. On April 6, the satellite accomplished a successful communication test with the Chang'e-4 spacecraft, currently engaged in an exploration mission on the far side of the moon. Subsequently, from April 8 to 9, it underwent communication trials with the Chang'e-6 probe, slated for future launch. Launched on March 20, Queqiao-2 reached its intended highly elliptical orbit around the moon on April 2, following midway correction, near-moon braking, and orbital manoeuvres.

00:00 China's National Space Administration announced on Friday that the Chuichao-2 satellite has
00:10 successfully concluded its orbit communication test, with both the platform and payload operating
00:16 as expected.
00:18 The CNSA affirmed that Chuichao-2 functions and performance are aligning with the mission
00:22 specifications, enabling it to deliver relay communications service for the fourth phase
00:27 of China's lunar exploration, endeavor, and forthcoming lunar missions undertaken by China
00:32 and other nations.
00:34 This milestone marks the Chuichao-2 mission as a resounding success.
00:37 On 6 April, the satellite accompanied a successful communication test with Chang'e-4 spacecraft,
00:44 currently engaged in its exploration mission on the far side of the moon.
00:48 Consequently, on 8 and 9 April, it underwent communication trials with Chang'e-6 probe,
00:54 slated for future launch.
00:57 Launched on 28 March, Chuichao-2 reached its intended highly elliptical orbit around moon
01:02 on 2 April following midway correction, near-moon breaking, and orbital manoeuvres.
01:08 Accompanying Chuichao-2 were two communication and navigation technology tests, Tiandu-1
01:12 and Tiandu-2, launched simultaneously.
01:15 The satellites achieved their target circumlunar orbits by 29 March and parted ways on 3 April.
01:22 Presently, they are engaged in series of assessments focusing on communication and navigation
01:26 technology.
01:28 Utilizing highly elliptical frozen orbits, Chuichao-2, Tiandu-1 and Tiandu-2 ensures
01:33 stable trajectories, minimizing deviation during their travels in space.
01:38 This orbit can bring many advantages to Chuichao-2 compared to the first aircraft, which was
01:43 launched in 2018 for Earth-Moon relay communication.
01:47 The orbit of Chuichao-2 is closer to the moon, which greatly improvises the communication
01:52 rate of data transmission.
01:54 Compared to the first Chuichao, which orbits around the second Lagrangian point of the
01:59 Earth-Moon system, Chuichao-2 has also significantly improved its communication coverage on the
02:04 south pole region of the moon.
02:06 This orbit also helps the satellite to save fuel, meaning that the spacecraft can stay
02:11 in this orbit for a long time with very little fuel.
02:14 Chuichao-2 will provide relay communication service for Chang'e 4 lunar probe and the
02:19 Chang'e 6 mission in the future as planned and carry out scientific exploration at an
02:23 appropriate time.
02:25 The deployment of China's relay satellite is a key step for the future lunar exploration
02:30 mission, especially for China.
02:33 The landing and sample collection sites of China's moon mission in the coming years are
02:37 mainly in the lunar south pole region or on the far side of the moon.
02:41 A powerful relay satellite with more function is necessary to provide communication and
02:46 data transmission services for the mission.
02:49 Chang'e 6 is scheduled for launch in the first half of 2024 with Chang'e 7 in 2026 and Chang'e
02:55 8 in 2028.
02:56 Chang'e 7 and 8 will be a form of basic model of lunar research station to carry out lunar
03:02 environment exploration according to the CNSA.
