This video from Kurzgesagt (fantastic channel, by the way) details how we might be able to give Mars an atmosphere and biosphere using our current […] Continue reading

Powered and Unpowered Gravity Assists

The farthest planets in the solar system are so distant, it is infeasible to reach them using only rockets. The delta-v, or change in velocity, required to propel a spacecraft to a gas giant like Saturn is far too impractical for today’s rockets to achieve. The main problem is that a spacecraft needs tons of […] Continue reading

Historical Astronomers in Context

Kepler, Galileo, and Brahe all lived at the same time during the late 1500’s for 30 years. Galileo and Kepler were then alive for another 29 years.. Isaac Newton is undoubtedly the most impactful of these astronomers. Newton invented calculus, pioneered classical physics, and derived the theory of gravitation. Calculus and physics are essential tools […] Continue reading
