- Abnormity was detected during flight of the rocket Long March-5 Y2
- The rocket was due to carry the heaviest Shijian-18 satellite
- Shijian-18 is China's latest technology experiment satellite
Abnormity was detected during the flight of the rocket, which blasted off at 7:23 pm (local time) from Wenchang Space Launch Center in southern province of Hainan, state-run Xinhua news agency reported.
Further investigation will be carried out, it said. The rocket was due to carry the heaviest Shijian-18 satellite.
The launch was the last test for the Long March-5 series before its mission to send the Chang'e-5 lunar probe into space in the latter half of this year, which was to return with samples. With a weight of 7.5 tonnes, Shijian-18 is China's latest technology experiment satellite and the heaviest satellite China has ever launched into space, an earlier report by Xinhua said.
It was aimed at testing China's new Dongfanghong-5 (DFH- 5) satellite platform and carry out in-orbit experiments including Q/V band satellite communication, satellite-ground laser communication technologies and an advanced Hull electric propulsion system, it said.
In April this year, China had launched its first cargo spacecraft, Tianzhou-1, into space using the country's heaviest Long March-7 Y2 carrier rocket to dock with the orbiting experimental space station which was expected to be operationalised by 2022.
Tianzhou-1 was larger and heavier than Tiangong-2, which is 10.4 meters in length and has a maximum diameter of 3.35 meters,weighing 8.6 tonnes.
