Even if we can prevent a global warming apocalypse, our planet won’t be safe forever – the sun will one day expand. So should we try to move the Earth to a wider orbit?
BepiColombo MPO at Mercury,
Spacecraft ESA, Mercury NASA
It will take more energy to get the BebiColombo spacecraft inro a stable orbit around Mercury than it would to send it all the way to Pluto.
Artist’s rendering of a Mars artificial gravity transfer vehicle.
It is possible to split water into oxygen and hydrogen gas in zero gravity using sunlight, shows new study.
Aircraft and missiles on display at Woomera, South Australia. Will we launch more rockets from here in the future?
We've launched rockets from Woomera in South Australia, but in reality Australia could support multiple launch sites. And the closer to the equator, typically the better.
The SpaceX Falcon Heavy rocket takes off from Cape Kennedy in Florida, USA on 06 February 2018.
The launch of Elon Musk's Falcon Heavy rocket is undoubtedly a spectacular feat of engineering - but the release of a sports car into orbit also says something about our values as human beings.
Falcon Heavy’s first payload will be a Tesla Roadster, set to become the world’s fastest car following its launch into a heliocentric orbit.
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.

To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.
The discovery of the year was the first detection of gravitational waves.
Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.
The SPARTAN re-usable space launch technology.
Whatever happens next in new space race will happen quickly. The opportunity is there for Australia to be involved, but it won’t be there for long.
Mars mission with plasma rockets concept.
Getting to Mars with current rocket technology will use massive amounts of fuel to move very small cargoes. There is a more fuel-efficient way.
SpaceX’s Falcon 9 rocket blasts off.
Yes, it really is rocket science.
The only way to fly the friendly skies – or dark voids of space.
We're on the cusp of being able to consistently launch and land rockets, greatly reducing the cost of space travel. But how long before there's a Millennium Falcon in every garage?
Unmanned rocket explodes moments after launch.
Cheap, affordable space travel would be revolutionary. Chances are, when it comes, it won't rely on the brute force approach of rockets.
One of the engineers behind Bloodhound, the UK's anticipated world land speed record attempt, explains how they created a car to reach 1000mph.
The Falcon 9 firmly rooted to the ground, for now.
The recent failure of the SpaceX Falcon 9 rocket presents something of a dilemma for NASA, which still has no domestic launch capability of its own to reach the International Space Station.
“This theory complex but important and – hey look, it’s Kim Kardashian!”
Making science 'sexy' leads us to keep looking in the wrong place for the things science could do for us.
Coming in to land – and attempt to recover the first stage of the potentially reusable Falcon 9 rocket.
There must be an easier way to rescue and reuse a rocket after the latest attempt by SpaceX ended in failure, again.
The scramjet crashed, but the experiment was a success.
