An Ariane 5 rocket lifted two communications satellites to space Wednesday to connect rural Australians with the rest of the world through high-speed Internet and extend television and data services over India, then completed experiments in orbit aimed at helping designers craft Europe’s next-generation launcher.

A prototype rocket for a massive reusable vehicle SpaceX is designing to fly people to the moon and Mars took off from a launching stand in South Texas on Tuesday, flew to a height of roughly 500 feet, then made a controlled descent to a nearby landing pad.

When the first Delta 2 rocket took off on Valentine’s Day 1989, ideas like navigating by smartphone and driving robots on Mars were science fiction. More than 150 launches over the last 30 years helped change all that.
