Space exploration brought ‘hope and joy’ during pandemic-devastated 2020 – 1News

While the planet continues to battle the Covid-19 pandemic, an Auckland astronomer says space is increasingly becoming a place of hope for many.

Stardome Observatory and Planetarium astronomy educator Josh Kirkley said 2020 space exploration was surprisingly really successful despite the pandemic.

There seems to be a lot more public interest in what's going on in space, he said.

Kirkley attributed the increased interest in space on the circumstances of this year.

I think [space] brings a lot of people a lot of hope and joy and excitement. Its something that brings a lot of people together.

Big players of the year included the US, China, Japan and India, as well as private companies like Elon Musks SpaceX and New Zealand-owned Rocket Labs.

I think it has been their most successful year, he said of the companies.

1 NEWS spoke to Kirkley about some of the most memorable moments in space this year and what he expected to see in 2021.

The 'once-in-a-lifetime' Great Conjunction

From Saturday until tomorrow night, Kiwis can enjoy a once-in-a-lifetime phenomenon known as a Great Conjunction. Itll see Jupiter and Saturn appear at their closes in almost 400 years on the western horizon shortly after sunset.

Planetary conjunctions themselves arent rare, but the rarity of this one is the closeness between the two planets from our perspective, Kirkley said.

Planets often pass by each other because all the planets orbit on the same plane. But, to see them this close is really rare.

So, itll still be really exciting.

The launch of Crew Dragon by SpaceX

On May 30, Elon Musks SpaceX became the first commercial rocket to take astronauts into Earths orbit. NASA astronauts Doug Hurley and Bob Behnken spent two months on the International Space Station before safely returning to Earth.

Moving to privatise some space trips was exciting because it would free governments up to focus on planetary missions, Kirkley said.

Its becoming so much more accessible and cheaper not just for NASA, but the entire industry to send people up to space.

Its a really positive thing all round.

Discovering water molecules on the moon

In October, NASA announced it had officially found water on the Moon.

Scientists have known for a while there was water on the moon, but they werent sure if it was just confined to the poles or some craters, for example, Kirkley said.

He said the discovery could have major impacts on future space travel.

For example, if we had lunar bases or rockets that are landing, they can actually use that as a natural resource.

Finding that resource, it's just invaluable the more you can actually be kind of self-sufficient, thats really useful.

Japan retrieves rock samples from asteroid Ryugu

December saw Japans space agency JAXA retrieve a small sample of rock from the asteroid Ryugu, which is some 300 million kilometres away from Earth.

Kirkley said the mission was significant because it gave scientists more clues about how the universe began and the origins of life on Earth.

What we know about asteroids is that theyre kind of the leftovers of the solar system.

The more we can understand what it was like when the solar system formed 4.5 billion years ago, it helps us to better understand how the Earth formed, how the Sun and all the other planets in our solar system formed, and eventually how life formed because we dont know that yet.

Looking ahead to 2021 Apollo era excitement and privatisation, but no space tourism yet

Kirkley said 2021 would bring much of the same, but just so much more.

Space tourism would continue to progress quickly in 2021, but it probably wont take off on a larger scale for another few years, he said.

Weve got all the missions going to Mars next year and a bunch of new planetary missions, he said.

We are kind of at a really pivotal point.

He said the move towards privatisation would also continue next year, with companies like SpaceX and New Zealand-based Rocket Lab at the forefront of innovation.

The high levels of excitement about space was probably something many hadnt felt since the Apollo era, he said.

But 2020 had a different flavour to it, he added.

When you look at Apollo, for example, the first Apollo mission to the moon literally had nothing to do with science they were kind of political statements.

Today, theres just a lot more effort towards science and discovery and exploration and cooperation between nations. ... Its a lot more positive, really.
