China's optical remote-sensing satellite Jilin-1 Gaofen 02C failed to enter the preset orbit on Saturday.
The satellite was launched aboard the Kuaizhou-1A carrier rocket from Jiuquan Satellite Launch Center at 1:02 pm.
The launch center said the mission failed because abnormal performance was identified.
Specific reasons of the failure are under further investigation.
