Video: Falcon 9 launch replays

SpaceX test-fired 27 main engines on a Falcon Heavy rocket Thursday in Florida, clearing a hurdle before installing three commercial communications satellites on the launcher for a mission to geostationary orbit later this month.

SpaceX Starship is set to propel itself into the record books today on its maiden flight, becoming the tallest, heaviest and most powerful rocket ever launched by humankind into space, topping a role call of famous and history-making heavy-lift launch vehicles including the mighty Saturn 5 that first took humans to the moon.

Seeking to become the fourth nation to successfully land on the moon, India launched an ambitious robotic lunar mission named Chandrayaan 2 on Monday, targeting a touchdown near the lunar south pole Sept. 6.
