FCC approves SpaceX’s plans to fly internet-beaming satellites in a lower orbit (3 minute read)
SpaceX has gained approval from the FCC to fly their Starlink satellites at a lower altitude of 550 kilometers. By operating at this orbit, Starlink will have a much shorter signal latency and will also require 16 fewer satellites. There have been objections to the approval by other companies such as OneWeb, who are developing their own satellite internet network, and Kepler Communications. They claim that Starlink will use similar signals to their satellites and will cause interference, and that there would be a higher chance of satellites colliding at that orbit. The FCC ruled that interference would not be an issue, and SpaceX claims that their satellites have thrusters and will be able to navigate out of the way of other objects. SpaceX aims to launch a total of 12,000 satellites, with at least 6,000 in the next six years.

'Biosolar leaf' project targets air pollution on London campus (2 minute read)
A new ‘Biosolar leaf’ is able to clean up carbon dioxide and release oxygen to the air more efficiently than normal trees. The invention uses minute plant life on solar panel structures that can be built almost anywhere. It also produces nutritious plant proteins. While other air-processing technologies require high pressures, this technique can clean air even in low-pressure environments. Council members in the UK are excited to be the first to roll out the technology.
