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.
The Moon belongs to all of us. Let's share in its beauty from afar without splashing around $100 million on a showy space trip.
We need Mars-level thinking to solve our energy and climate problems here on Earth.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
The recently broadcast TV mini-series, “Mars”, combines fiction and nonfiction in a way that places them in balance. This kind of combination is likely to feature in more television series and films.
Musk's know-how cannot be dismissed but there are significant challenges standing between him and his dream of colonising Mars.
A true plan for the colonisation of Mars should include both the social and technical feasibility of living there. Unfortunately, Musk left that bit out.
