Why Scuba Training Is Important For Becoming An Astronaut

Scuba training has many aspects in common with a career as an astronaut.

The mutual themes are:

  • We need to rely on equipment both in space and underwater whenever we do activities. 
  • Even if an emergency happens, there is no way that we throw away life support systems. 
  • To achieve safety and effectiveness, it is critical to have a deep understanding of both the technology we use and the extreme environment that surrounds us.

That being said, being trained underwater as a scuba diver will benefit astronauts to simulate a space environment.

Also, most astronaut training is done underwater https://www.nasa.gov/content/underwater-spacewalk-training https://www.scubadiving.com/nasas-underwater-lab

Moreover, many current astronauts were enjoying scuba diving even before they became astronauts.

How Can You Do Scuba Diving Training? What Does The Process Look Like?


There are multiple organizations that give you certification.

I mainly do training with either PADI or SSI instructors.


Each organization has slightly different certification requirements, but basically they are the same.

For example, PADI has 4 types of certificates for recreational divers.

  • Open Water Diver (OW)
  • Advanced Open Water Diver (AOW)
  • Rescue Diver + Emergency First Responder (EFR: CPR+AED)
  • Master Scuba Diver (MSD: 5 specialty courses are additionally required)

If you want to be a professional instructor, you will proceed with Divemaster to have a further advanced license.

My Goal For Scuba Diving

I am currently trying to get Masterdiver, which is the highest stage for recreational divers. (I got OW in February 2021, AOW in May 2021, and Rescue in June 2021)

Also, I hope to get Divemaster someday so that I can get more professional technique and knowledge.

Final Remark

Although I recently started scuba diving, I became a huge fan of this activity. 

I have learned a lot through scuba journey, and I am really excited to be a Masterdiver (and hopefully Divemaster)!
