Both Voyagers are now in interstellar space.
Voyager 2 launched in 1977 and visited all four gas giants in our Solar System. It's now almost 18 billion kilometres from Earth and has finally joined its twin in interstellar space.

Air resistance makes it near impossible to predict the path of a crashing satellite.
There are loads of applications for 3D printers in space.
Using terrestrial forensic science to point the finger of blame to criminals in space will be much harder than it looks.
The idea that there’s a moral imperative for humans to expand beyond Earth is echoed by influential proponents of space exploration.
Technology had enabled humans to explore the deep sea, the Earth's poles, and outer space. But we shouldn't forget historical lessons about frontiers in the process of traversing them.
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.
There's more to sleeping in space than just nodding off.
The plan to use lasers to send mini-spaceships to the stars.
It's an ambitious plan to send a micro-spaceship to our stellar neighbour but is this possible with today's technology or even technology in the near future?
Are we soon to visit Alpha Centauri (left)?
Building a tiny starship may be doable. The big challenge will be making sure it survives all the hazards in interstellar space.
New Horizons continues to help unravel the icy dwarf planet’s secrets.

After last summer's Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here's some of what scientists have learned so far from that rich, slow cache.
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?
Spaceplanes seem like a great idea – perhaps one that has come too late.

Nimble and cheap commercial science could be the way to get more eyes in the sky.
Everything in space is so far away, but probes bring us closer.
The future of space travel?
A prototype solar sailing satellite has just successfully been deployed in orbit, pointing the way to the future of space travel.

After ten years in space NASA probe will get up close and personal with Mercury a final time.
I’ve seen the future, and the future’s blue.
It's no TIE fighter, but the Dawn probe is driven by the future of spacecraft propulsion: ion engines.
We have lift-off.
After a 24-hour delay due to bad weather, the first test launch of the Orion spacecraft by NASA is underway with the ultimate goal of putting human beings on Mars. Weeks after the landing on a comet by…
