Where Did We Get Our Water?

Posted on March 7, 2023 by Trevor Pillow

We know that Earth is the only planet in the solar system currently capable of housing liquid water. The other planets are too low pressure or too hot for water to exist as it does on Earth. However, other bodies in the solar system do have solid water, also known as ice! The moon and […] Continue reading →

Powered and Unpowered Gravity Assists

Posted on February 12, 2023 by Trevor Pillow

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

Posted on February 2, 2023 by Trevor Pillow

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 →
