What has space exploration ever done for us?
Space flight began with superpower prestige - and the race to put a man on the moon. What began as human adventure delivered technologies which changed the world. I want to discuss today, what space exploration has given us and if it is worth it. Maybe it has gone too far, should we slow down? These are the perplexing questions I want to answer in this post.
Firstly, space exploration has helped us to invent some great things that have aided us hugely on earth:
Scratch-resistant lenses ~ After NASA developed scratch-resistant astronaut helmets (to avoid damage from space flight), they continued experimenting with scratch-resistant plastics, which now comprise most sunglasses and prescription lenses.
Artificial limbs ~ Innovations originally designed for space vehicles, including artificial muscle systems, robotic sensors, diamond-joint coatings, make artificial human limbs more functional, durable, comfortable and life-like.
LASIK ~ The technology used to track astronauts' eyes during periods in space in order to assess how humans' frames of reference are affected by weightlessness has become essential for use during LASIK surgery. The device tracks a patient's eye positions for the surgeon.
Workout machines ~ Because prolonged exposure to zero-gravity leads to bone loss and muscle atrophy, NASA created workout machines to enable astronauts to maintain physical fitness while in space.
As you can see, due to what astronauts use in space, scientists have been able to make life-changing items for problems on earth. I think this is great because, without space exploration and what the astronauts need, limbless people wouldn't be able to walk and run comfortably with a prosthetic and unlucky people with bad or no eyesight wouldn't be able to fix these issues and can see perfectly. Furthermore, this is amazing and I strongly believe that what we as humans have achieved because of space exploration is definitely something to be celebrated. However, it might have gone too far, should we slow down?
Billionaire entrepreneurs are trying to create rockets fit for human travel, while government agencies spend billions furthering their explorations. But we are still a long way off from making our way to Mars. I understand that we are able to invent incredible things thanks to space exploration but we are getting no closer to our ultimate goal of being able to survive on another planet. At the moment what we are doing is great but we are also losing sight of the most important thing and this is not ok. People on Earth may not survive another 30 years if a nuclear war happens or climate change has become far too irreversible (we aren't far away from that currently) with that being said, I am confused, do we need to start focusing more on surviving on earth or another planet than great inventions? So what do you think? Are the inventions a distraction from the ultimate goal? Has it gone too far? Comment your thoughts below. Thank you for reading.
