Japan has launched the first in a new generation of space rockets, hoping the design will make missions more affordable.

The Epsilon rocket is about half the size of Japan's previous generation of space vehicles, and uses artificial intelligence to perform safety checks.

It was carrying a Sprint-A telescope which is being billed by Jaxa as the world's first space telescope that will remotely observe planets including Venus, Mars and Jupiter from its Earth orbit.
