New experiment on the International Space Station could help us tackle muscle loss in astronauts.
It has been 10 years since Elon Musk's SpaceX launched the commercial space age. What hurdles must be overcome before private companies begin exploring, colonizing and mining other planets?
Our 'Tony Stark' image of tech moguls is obscuring the talent and toil of ordinary workers, and inflating the egos of the bosses.
Space mining has the potential to provide a greater supply of resources either for being exploited locally for construction or being sent back to earth.
Iridium's latest launch brings its next-generation satellite network close to completion. But will it be put to the sword by a whole set of smaller rivals?
Elon Musk is an open admirer of the fictional Tony Stark, whose alter‑ego is none other than Iron Man. But Tesla’s recent financial results prove Musk to be more vulnerable than his hero…
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.
Tech companies such as SpaceX, Facebook, Google and Microsoft are competing to bring internet to areas without access in the developing world. And that's a problem.
With any type of human exploration, there are risks as we push boundaries, and there are inevitably mishaps and fatalities as a result. Space tourism is no exception.
Elon Musk is a master of keeping investors believing in the dream of Tesla, but analysis of the company’s output and financials reveal a darker picture.
Automatic feedback control is what enabled the Falcon Heavy rocket boosters to land. It also drives most of our technology – and even describes the fundamentals of how humans and animals behave.
From damaging the environment to contaminating the solar system, SpaceX's successful launch of the Falcon Heavy rocket also poses risks.
SpaceX's Falcon Heavy could propel two fully loaded city buses more than 50 times the height of Mount Everest at 32 times the cruising speed of a Boeing 747.
Private companies are increasingly challenging national space agencies in a new space race, which comes with great opportunities but also huge risks.
Musk’s audacious plan to blast people to Mars by 2024 glosses over some important social and political challenges that SpaceX will need to successfully navigate to get off the ground.
Sending humans to Mars is a 5-10 year project goal for several global operators right now. It's expensive - but Elon Musk unveiled his new commercial plan today.
Space exploration is exciting - but there are barriers for humans hoping to visit and even stay on planets. Buried ice on Mars could be a water source for interplanetary visits of the future.
In the current commercial space race, the idea of reusing rockets is gaining momentum.
Musk dismisses one of the main technical challenges of being on the Martian surface: the temperature.
We could learn a lot from any mission to send people to Mars, such as whether there's life elsewhere in the universe or even the technology for new household appliances.
