The Observer view on the future of space travel

Entrepreneurs such as Elon Musk hold the key to exciting and important possibilities

The sight of the giant Falcon Heavy rocket roaring into space after its launch last week will have brought, if nothing else, a nostalgic tear to the eyes of many experienced space hands who had gathered to witness the blast-off.

From the same Kennedy Space Center launch pad that saw Apollo rockets soar towards the moon, a new launcher, built by Elon Musk’s SpaceX company and currently the most powerful in the world, made its dramatic maiden flight. Hopes that the great pioneering days of US space flight, in the 1960s and 1970s, would soon return were suddenly rekindled. The fact that Falcon Heavy’s cargo was ferrying an electric sports car, built by a different Musk company, Tesla, to Mars only added spice to an already extravagant event.

Musk had made it clear that Falcon Heavy’s launch should be a fun event and there was certainly an irreverent aspect to the aiming of a sports car at a distant planet. But we should be careful not to dismiss the proceedings as being more about drama and entertainment than it was about serious technological development. In fact, last week’s launch represents a very important step in the progress of space flight. For the first time, an entrepreneur showed what could be achieved with a bit of imagination and boldness.

Just consider the construction of the Falcon Heavy. Unlike previous space launchers, its lower stages, after using up their fuel, were not dumped in the upper atmosphere and allowed to break up over the oceans. Instead, they were gently returned to Earth using retro rockets for subsequent reuse on other launches, a procedure that Musk has already pioneered on lighter versions of his Falcon rockets.

It was a highly sophisticated operation and typical of the technological fixes that Musk is employing in order to slash launch costs and bring him close to his dream of making spaceflight affordable and accessible.

And that is a laudable goal. For decades, humanity has struggled to find a role for itself in deep space (as opposed to near Earth space where telecommunications, meteorological and environment satellites provide direct enrichment of lives). A few great deep-space missions have been achieved, it should be stressed, such as the Cassini probe that flew to Saturn and the Hubble space telescope. But all were vastly expensive. Only governments could afford the cost of their construction.

That may soon change, however. In the wake of Falcon Heavy’s success, Musk has said he will soon offer launches for around $90m (£65m) for major payloads, a figure significantly lower than the $300-400m (£217-290m) price tag offered by Falcon Heavy’s nearest rivals.

At such costs, a slew of missions, including probes to study the sun, to hunt planets orbiting other stars and to seek life in the icy moons of Jupiter and Saturn, suddenly look feasible. It remains to be seen if Musk can maintain the success of his Falcon Heavy rockets, of course, but most space analysts place considerable faith in his SpaceX company.

Nor is Musk the only businessman who is threatening to transform the space industry. Others include Jeff Bezos, founder of Amazon, whose company, Blue Origin, has its eyes on lunar colonisation, and Richard Branson, whose Virgin Galactic aims to carve a tourist market by flying holidaymakers into space for brief trips. Others have their eyes on mining asteroids for rare metals while some seek to build orbiting hotels.

Only time will tell which of these space visionaries will succeed. What is important is that private industry takes on a far greater role in space exploitation in the near future and stops acting merely as contractors that follow government agency wishes.

In this way, they will be following the paths of entrepreneurs who opened up aviation to the masses and who took the emerging science of computing technology and gave us smartphones and tablets. It is an enticing prospect that offers rich rewards to entrepreneurs – and to society.

Since you’re here …

… we have a small favour to ask. More people are reading the Guardian than ever but advertising revenues across the media are falling fast. And unlike many news organisations, we haven’t put up a paywall – we want to keep our journalism as open as we can. So you can see why we need to ask for your help. The Guardian’s independent, investigative journalism takes a lot of time, money and hard work to produce. But we do it because we believe our perspective matters – because it might well be your perspective, too.

I appreciate there not being a paywall: it is more democratic for the media to be available for all and not a commodity to be purchased by a few. I’m happy to make a contribution so others with less means still have access to information. Thomasine F-R.

If everyone who reads our reporting, who likes it, helps fund it, our future would be much more secure. For as little as £1, you can support the Guardian – and it only takes a minute. Thank you.
