Galaxy Fold first look at Samsung's Unpacked
Samsung gave its foldable phone an official name and revealed when you can buy it. (Warning: It isn't cheap.)
In this series we take a look at everything, large and small that has changed the way we do things and has enhanced our lives in some way. In part two we take a look at advancements in transportation that have changed the way we travel the world - and beyond.
To overcome the force of the Earth's gravity and propel a craft beyond the surface of the earth requires a significant amount of power. Rockets give spacecraft the initial thrust to help it climb to a high enough altitude to overcome gravitational pull.
The rocket is then jettisoned and the spacecraft enters Earth's orbit. Space travel was first theorised in 1861 by Scottish astronomer and mathematician William Leitch. The first space craft to reach the moon was Luna 2 in 1959.
