Space exploration: A luxury or a necessity?

“Oh, come on Daniel, space journey is so costly, and pointless!” These had been the phrases of my buddy Max, throughout a Christmas occasion the place I used to be discussing my thesis undertaking: finding out locations on Earth the place the dwelling circumstances are so excessive, they might maintain classes for future space missions.

This disdainful angle towards space analysis is definitely fairly widespread.

House exploration is at present booming. Simply consider the Artemis missions, SpaceX’s formidable plans for Mars, the deployment of the James Webb telescope or the current “race to the moon.”

Quite a few large-scale tasks are getting the inexperienced mild now, primarily from NASA, together with the Artemis II mission that may carry 4 astronauts to the moon, which will have Canadian astronaut Jeremy Hansen aboard. This will likely be a primary since 1972. Extremely, it has been 50 years because the final human mission to Earth’s pure satellite.

Though many individuals discover space exploration inspiring, others are skeptical and even angered by what they see as an unjustifiable waste of assets and cash on an exercise that solely spreads air pollution to a different place. This sums up the sentiments of my buddy Max.

On this article, I’ll attempt to show him unsuitable.

People are explorers first

My great curiosity has led me to travel to extreme places so I can study them. However I’m not the one one with this need to discover.

In my Grade 9 historical past class, my trainer stood on high of her desk and, with a grave and severe tone, went on to behave out Jacques Cartier’s arrival in North America in her personal, colourful fashion. Just a few years earlier, I had discovered about how the primary people left their caves to climb mountains. One hundred and thirty years ago, humans sailed further and further south until they saw the glacial landscapes of Antarctica for the first time. On the similar time, people had been trying to dominate the skies and aiming for the past with planes and rockets—which is how we obtained to the moon.

What’s the widespread denominator in our historical past? Exploration, after all.

Human nature is characterised by a propensity to journey, to look additional and to find. We’re all curious by nature. If we cease eager to discover, we cease being human.

The Earth has rings

So, my buddy Max, let me invite you exterior. It is a stupendous, starry night time with no moon. It is a bit chilly, however at the very least the ambiance is not too humid, which makes the sky extra clear. We are able to see stars flickering. Some are blue, others are purple. And the extra our eyes adapt, the extra the sky reveals its secrets and techniques.

Instantly, one thing else stands out. It is one other mild, however it’s not flashing, and it is transferring fairly rapidly. A shooting star? No, the atmosphere would have burned it up in a few seconds.

It’s a satellite, one of thousands that orbit the Earth like rings. These satellites are a direct consequence of space exploration. We’d be dwelling in a very completely different world with out them.

Indeed, not an hour goes by in our lives when we don’t use a satellite.

On the one hand, you’d seemingly have gotten misplaced in your means right here, Max, as a result of there would have been no GPS to point out you which ones exit to take. And secondly, I would not have been in a position that will help you discover your means as a result of there can be no wifi. We are able to push our considering even additional; agriculture, environmental monitoring, communications, the climate, even banks, all of those rely on satellites.

However how does this work? You must perceive that these satellites transfer so rapidly they really circle the Earth a number of instances a day. Mixed with a really giant workforce, they supply an entire view of the globe. From the center of the oceans to the best mountains and the virtually inaccessible poles, we have now eyes all over the place. By drawing on this huge amount of observations, we obtain data on changes to the earth’s surface, the spread of forest fires, the movement of winds, the melting of ice and many other things, while enabling global communication and credit card transactions.

House exploration was the set off that enabled us to develop and function these applied sciences. And it does not cease there.

Two birds, one stone

The observe of medication in remote areas additionally advantages from space exploration. It isn’t straightforward for communities in distant areas to entry well being care, particularly since hospitals do not at all times have the subtle gear they want.

If you consider it, when astronauts discover space, they change into a small inhabitants in a really, very distant area. It is true. What occurs if somebody has a extremely unhealthy abdomen ache? Or breaks an arm? They do not have time to return again house for therapy, so we have now to react, and rapidly.

Scientific analysis in telemedicine has developed to deal with this necessary problem, producing numerous modern applied sciences. And if these are helpful for astronauts, why not use them for rural populations, too?

Just a few years in the past, three Québec researchers from different universities were working on a tiny probe that could rapidly analyze and diagnose a blood sample.

Though some prototypes aren’t but available on the market, others are already in widespread use, such because the ultrasound scanner designed by NASA. This scanner takes exact photographs of organs and bones that may be transmitted to a health care provider, who will then have essential data available to suggest therapies.

In a means, space exploration gives us with alternatives to reply to pressing wants on Earth. So, Max, are you starting to see the necessity for it?

One other perspective

Lastly, I’ve to confess that I discover it fairly encouraging to see Russians, People, Japanese, Canadians and Europeans dwelling collectively on the House Station. Not so way back, a few of these nations had been attacking one another with nuclear bombs. In space, no such borders exist.

Exploration brings individuals collectively. It opens our eyes to new views. It exhibits us that we’re all in the identical boat collectively. That is fairly necessary, do not you assume, Max?

Our planet is magnificent and distinctive, an oasis of inconceivable life. However it’s fragile. We have to defend it. That is why exploring past the Earth shouldn’t be thought of a luxurious; it is an funding in our shared humanity.

So, Max, when Jeremy Hansen and his crew take off in 2025, will you be there to look at them?
