China launched a new test communication satellite on Thursday in a pivotal step to validate technology essential for next-generation orbital connectivity speeds and reliability.

The Communication Technology Test Satellite No 25 was sent into orbit on a Long March 5 rocket launched from the Wenchang spaceport in the southern island province of Hainan at 3.30pm on Thursday.

“The satellite will be mainly used to verify multi-band, high-rate satellite communication technologies,” state broadcaster CCTV reported.

The mission is the 11th flight for the Long March 5 series and its first launch of the year.

The Long March 5 has a carrying capacity of 25 tonnes to low-Earth orbit, 14 tonnes to geostationary transfer orbit and 8.25 tonnes to trans-lunar injection, suggesting that the satellite deployed in this mission was relatively heavy.
