Prof Brian Cox says he is prepared to boldly go where no British TV presenter has gone before.
“I’ve not yet raised the funds, or convinced someone to give me a ticket,” he explains.
But if Elon Musk, the owner of US aerospace company SpaceX came calling, then “I’d say… brilliant, up we go!”, he adds.
The most famous particle physicist in the UK, Prof. Cox, believes that one day, we could all be space travelers.
He expresses his desire for humankind to advance ahead of his upcoming Solar System-themed BBC Two series.
He claims that technological advancements at some for-profit space companies raise the prospect of human becoming an interplanetary and multiplanetary civilization.
The crew of SpaceX’s Polaris Dawn, led by billionaire businessman Jared Isaacman, is one group that has beaten Prof. Cox into space.
Earlier this month, Isaacman created history by being the first astronaut from the private sector to walk in space. The mission was hailed by the US space agency NASA as “a giant leap forward” for the commercial space industry.
Prof. Cox thinks it’s a good idea for government organizations like NASA and private businesses like SpaceX to work together on this combined approach. He continues, “Having inexpensive, dependable access to space is essential.”
He states, “I really believe that our civilization needs to spread beyond our planet for a variety of reasons.”
The aerospace company, Blue Origin – brainchild of billionaire and Amazon founder, Jeff Bezos – is already envisioning a future where people live and work in space, with industries perceived as damaging to Earth moved into the cosmos.
There are limited resources on the Earth and damage is being done to the planet through “civilisation’s thirst and requirement for more resources”, says Prof Cox, making it imperative we look towards becoming a multi-planetary civilisation.
Tapping into the universe’s resources, like mining asteroids, may sound like science fiction but, he says, “it’s extremely important that we do it, and as quickly as possible”.
Whether there is the political skill to achieve it as a civilization is another matter, he says – but he believes we have a duty to explore our galaxy, the Milky Way, which is filled with hundreds of billions of stars.
There is plenty to explore in our Solar System alone. As well as the Sun there are eight planets, five officially named dwarf planets, hundreds of moons, thousands of comets, and more than a million asteroids.
If forced to hazard a guess, Prof Cox says it is probable that we are the only advanced civilization in the Milky Way at the moment, and possibly the only one that has ever existed in the galaxy.
“If that’s true, though, then our expansion beyond this planet becomes an obligation. Because if we don’t do that, nobody’s doing it. So if we don’t go out to the stars, nobody’s ever going out to the stars in this galaxy.
“So it becomes of overriding importance to begin to take those first steps.”
Mars and the Moon are the only two places Prof Cox could imagine seeing anybody visit and begin to build a permanent presence in his lifetime.
Despite asteroids the size of stadiums hurtling through the Solar System, he believes the biggest current danger to Earth is actually its human inhabitants.
“If anything’s going to destroy us, it’s probably us,” he says – although having said that, he says the possibility of an asteroid hitting the Earth is now being taken more seriously than when he first started making TV programmes more than 15 years ago.
“At some point, we’re going to have to move one,” he says.
For his new series, Prof Cox explores events happening in space via the latest missions. In October, Nasa’s Europa Clipper, will be setting off on a five-and-a-half-year journey to Jupiter – to explore whether the planet’s icy moon, Europa, could harbour conditions suitable for life. Scientists believe Europa has liquid water in the form of a large saltwater ocean beneath its icy crust.
But what might life on Europa look like if the conditions were right?
“It will be simple life,” says Prof Cox. “It will be single-celled life at the very best, or something that looks a bit like single-celled life… We’re not expecting multi-cellular life there – partly because it took so long to develop here on Earth.”
It has been more than 10 years since Sir David Attenborough named Prof Cox as his natural successor. So could he be ready to take on the mantle?
“I’m absolutely delighted that he doesn’t need a successor at the moment,” says Prof Cox, “he’s making more programmes than I do.”
When it comes to Sir David’s career, he says, it is not possible to succeed someone who has invented the form.
“You can’t really have a successor because he was the first to do it. It’s almost like saying: ‘Who will be the successor to Neil Armstrong as the first human to set foot on the Moon?’”
