The spacecraft-killing anomaly over South America

Over the years, the SAA has been responsible for several spacecraft failures and even dictates when astronauts can and canā€™t perform spacewalks. As the space around Earth becomes filled with an increasing number of craft, what does the SAA mean for the future of spaceflight?

This post is from back in February 2021, but I just stumbled across it this morning and thought it was an interesting read.

This part caught my eye…

Radiation is a colorless, tasteless, and odorless enemy…

…and I couldn’t help thinking…

Iocaine powder?!?

It’s okay. I’m immune šŸ˜‚

Anyway, the article linked above is food for thought. Whenever electronic objects pass through the SAA, which is where the loops of the Van Allen Belt dip perilously close to the Earth, the electronics get a massive amount of radiation and go haywire.

Seriously expensive to shield stuff up there — and as more and more satellites (and people) go up, so does the risk.

Where are your nuclear wessels?

Astronauts on a trip to Mars would beĀ exposed to very high levels of radiationĀ which can cause seriousĀ long-term health problems such as cancer and sterility. Radiation shielding can help, but it is extremely heavy, and the longer the mission, the more shielding is needed. A better way to reduce radiation exposure is to simply get where you are going quicker.

Hmm. So putting them in a ship with a giant nuclear fission reactor is safer?

I think somebody may want to come up with a backup plan…
