Q&A with Heino Falcke, principal investigator of the Netherlands-China Low-Frequency Explorer (members only)

A Chinese communications satellite heading for geostationary orbit more than 22,000 miles over the equator lifted off Thursday from the Xichang space base in southwestern China aboard a Long March 3B rocket on the first space launch of 2019.

A large rocket stage left in space after the successful launch of China’s heavy-lift Long March 5B rocket May 5 fell into the atmosphere Monday over the Atlantic Ocean, becoming the most massive object in nearly 30 years to perform an uncontrolled re-entry from orbit.

The Chinasat 9A communications satellite has arrived at its operational perch more than 22,000 miles over the equator after a Long March rocket deployed the craft in a lower-than-planned orbit last month due to a roll control error in the launcher’s third stage, according to China’s top state-owned aerospace contractor.
