SLS vs Starship: Why Do Both Programs Exist?

NASA just announced the lunar landers for the Artemis program. To everyone’s surprise, SpaceX’s massive Starship is one of three landers NASA chose alongside Blue Origin and Dynetics. Understandably, this is bringing up a lot of questions. Some of which we will answer in my next video/article: “Should NASA just cancel SLS and use Starship and/or other commercial launchers for Artemis?” But today I think we need to settle a lot of debates about these two rockets first. Now, more than ever, it is time we truly compare them head-to-head.

Soyuz MS-16 | Soyuz 2.1a

A maiden flight of sorts. This is the first Soyuz 2.1a rocket to carry humans into space. It will transport the crewed Soyuz MS-16 spacecraft to the International Space Station. The crew consists of Russian cosmonauts Anatoli Ivanishin and Ivan Vagner, and NASA Astronaut Christopher Cassidy. They will complement the crew of Expedition 62 and continue its work with Expedition 63.

How much do rockets pollute?

Some might find it ironic that an organization like NASA, who studies our atmosphere, is ok with rockets polluting it so much. Or isn’t it weird that Elon Musk, the same person who is pushing  sustainable energy with Tesla also has a rocket company that runs on fossil fuels? So today we are going to do a deep dive into this. We are going to see just how much of what rockets emit, go over how much different fuels and engine types pollute, then we will compare their emissions against other forms of transportation and other global polluters.
