Live coverage: Two satellites lift off aboard Ariane 5

Arianespace plans to launch an Ariane 5 rocket from French Guiana on Sunday after fixing a disconnected helium vent line that required the launcher be returned to a hangar for repairs.

After months of delays caused by the coronavirus pandemic, Arianespace scrubbed back-to-back Vega launch attempts Saturday and Sunday due to unfavorable high-altitude winds over the European-run Guiana Space Center in South America. The Vega rocket is awaiting launch on a rideshare mission carrying 53 small satellites into orbit for 21 customers in 13 countries.

A Russian Soyuz launcher fired into orbit from the remote steppe of Kazakhstan Thursday with 34 satellites built on Florida’s Space Coast, commencing a sequence of launches to deploy a network of nearly 650 spacecraft for a global broadband network owned by OneWeb.
