US space agency NASA is set to take another giant leap for mankind as it prepares for the maiden voyage of its new moon rocket. No humans will be aboard the powerful Space Launch System (SLS) spacecraft when it blasts off on 29 August, but in the coming years it will send astronauts to the lunar surface for the first time in more than 50 years, and maybe one day to Mars. Future missions using SLS’s have been dubbed Artemis after the twin sister of Greek god Apollo, and the first crewed flight should take off in 2024, with a 2nd the following year set to put the first woman on the moon. And if you’re after the thrill of high speeds but can’t snag a spot aboard a rocket, American Airlines has agreed to purchase 20 supersonic jets, which can fly twice as fast as regular commercial aircrafts. Seven hours to LA – yes please…
