Virgin Galactic’s Unity VSS spacecraft went on a suborbital test flight in May 2021.
Both Virgin Galactic and Blue Origin are sending spacecrafts – and their billionaire founders – into suborbital flight. But what differentiates a suborbital flight from a trip around Earth?
Some UFO sightings appear to demonstrate ‘advanced technology’. The Pentagon has confirmed some threaten flight safety, and potentially national security.
A tiny speck of asteroid dust, circled, can only be manipulated by a glass needle.
A minuscule particle of asteroid dust has helped reveal how celestial rocks like Earth might have sprouted life.
The space laws designed to protect planets and moons from contamination.
We’ve already sent probes to land on Mars. The challenge now is to get people there and bring them home again.
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.
The Changzheng-2F rocket with the Shenzhou-10 manned spacecraft heading to Tiangong-1 in 2013.
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.
Goddard Space Flight Centre
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.
