HELSINKI — China has quietly rolled out a brand new Lengthy March 7A rocket at a coastal launch website in preparation for launch of a ‘know-how verification satellite tv for pc’.
Official acknowledgement of an mission involving the brand new launcher got here on Feb. 12 (Chinese), however with no indication of its timeline.
Nevertheless images shared by Chinese language area program watchers in China recommend the Lengthy March 7A has already been rolled out to its launch pad on the Wenchang Satellite tv for pc Launch Middle.
Launch shouldn’t be anticipated imminently as no airspace closure notifications have been issued. The opening of the tower suggests coaching and testing workout routines will precede launch.
The terse discover stating that the Lengthy March 7A was at Wenchang got here from a subsidiary of the China Aerospace Science and Know-how Company (CASC), the nation’s principal area contractor, which added that the payload for the mission is called ‘new know-how verification satellite-6’. The title of the satellite tv for pc sequence is outwardly new, regardless of the satellite tv for pc in query being designated ‘quantity 6’.
No indication of the applying of the satellite tv for pc, which will likely be despatched to geosynchronous switch orbit (GTO), was offered. Geosynchronous orbits are sometimes used for communications, navigation and meteorology.
Different makes use of embody warning programs such because the U.S. SBIRS missile warning system. China doesn’t presently have confirmed early warning satellites.

Lengthy March 7A for GTO launches
The Lengthy March 7A is known to be a variant of the usual Lengthy March 7, which has flown twice. The brand new launcher makes use of the identical three.35-meter-diameter kerolox core and 4 2.25-meter-diameter facet boosters however contains an extra hydrolox third stage adopted from the older technology Lengthy March 3B rocket to permit it to ship payloads to GTO.
