Space elevators, a way of getting cargo and materials into space without rockets, have made frequent appearances in science fiction for decades. Making them a reality, however, is challenging. In this latest edition of Periodic Graphics in C&EN, we take a look some of the material requirements for space elevators, and which existing materials might be close to meeting these requirements. See the full graphic on the C&EN site.
Rockets require a huge amount of energy to launch into orbit. In the latest edition of Periodic Graphics in Chemical & Engineering News we look at the different types of fuels used to get rockets off the ground and how spacecraft continue to propel themselves in space.
