As governments and private companies race to put satellites into space, there will be an unprecedented demand to clean up dangerous debris. The main causes of space debris are collisions between satellites. For some perspective, 3200 non-operational satellites currently orbit Earth and around 12,000 satellites are expected to be launched as part of Starlink alone. Their purposes range from GPS to environmental monitoring in the Amazon and collectively, they are responsible for the smooth operations of all elements of our lives. However, the presence of debris threatens to cripple this critical infrastructure.

And how we might solve them

Introduction

In early 2013, Elon Musk introduced the Hyperloop. It promised to be a revolutionary form of transportation. With a proposed speed of 760 mph or 1220 km/h, Hyperloop will be the fastest land-based system to exist.

Inside a vacuum tube, pods are accelerated at high speeds since there is little air resistance. Instead of moving on rails like bullet trains, Hyperloop uses magnetic levitation(maglev) to avoid any friction that would slow it down.

Besides offering lightning quick speed⚡️- it could also reduce deadly car crashes, connect people living far away, and create a sustainable…
