SpaceX is gearing up for the first full-up test-firing Thursday of all 33 engines on the booster for the company’s Starship mega-rocket in Texas, a critical milestone on the path to launching the giant vehicle on its first orbital test flight, which could happen as soon as March if this week’s test goes well.

India’s GSLV Mk.3 rocket took off Monday on its first full-scale orbital test flight, delivering the GSAT 19 communications satellite to an on-target orbit after successfully demonstrating new solid rocket boosters, a twin-engine core stage and an upgraded cryogenic upper stage engine.
