India’s Polar Satellite Launch Vehicle lifted off at 2234 GMT (6:34 p.m. EDT) Wednesday with the country’s ninth navigation satellite, bolstering a regional positioning and timing network after the loss of a navigation craft on a previous PSLV mission last year.

An Ariane 5 countdown in French Guiana was aborted Tuesday with the European-made rocket’s main engine already running, postponing the launch of two commercial communications satellites until engineers can resolve the problem.

On the eve of launching its first ViaSat 3 internet satellite on a SpaceX rocket, Viasat says it has moved the launch of an identical spacecraft off of Europe’s long-delayed Ariane 6 rocket, and is considering bids from other rocket companies.
