Tragedy: Challenger exploded shortly after launch from the Kennedy Space Centre.
We should honour the dead by striving to go further.
Ceres, as seen by NASA’s Dawn spacecraft on December 10, around a crater chain called Gerber Catena.
Dawn's mission director and chief engineer describes his 'dream come true' job – and how the new data coming back from Ceres could unlock some of the secrets of the earliest days of our solar system.
‘I am C-3PO, human-cyborg relations. And this is my counterpart R2-D2.’
No Star Wars movie would be complete without the Universe's two favourite droids. But now the race is on to turn them into fact.
Hello beautiful! R136a1 is a universal heavyweight.
Think our Sun's big? Prepare to be dazzled by the real galactic heavyweights.
Tim says bye.
What does it feel like to prepare for a journey to space? Space scientist Monica Grady followed astronaut Tim Peake around for a few days before his launch to find out.
I’m not coming in. I might catch something.
New research shows that bacteria is thriving on the ISS. But is that really such a bad thing?
Unlike science fiction films featuring grotesque aliens and faraway galaxies, Ridley Scott’s The Martian depicts a sci-fi space mission that could soon be science fact.

NASA has set a target date of 2030 for a manned mission to Mars. With no real scientific breakthroughs needed, success depends on developing the proper technology.
This digital false-colour image shows the dark, narrow streaks on Martian slopes inferred to be formed by seasonal flow of water on the planet. The streaks are roughly the length of a football field.

A giant golden mirror is on the brink of opening up a glimpse of the very first galaxies to be formed.
Jean Paul Santos with the finished 4x4 sub-array antenna assembly that may help rovers talk directly with Earth.
New research provides a compact but powerful way for Mars rovers to communicate directly with Earth via an array of smaller antenna elements, bypassing the need for an intermediary.
Hot spot for much-needed research.
The House proposes slashing funding for earth science from NASA's budget, yet this science is critical to understanding – and coping with – the dramatic effects of a warming Arctic around the world.
Many of the bodies in our solar system’s contain precious resources that could be used here or in space.
Mining in space is no longer science fiction. But could it end wars over resources, as Neil deGrasse Tyson has suggested?
Space scientists have a busy decade ahead with plans to visit Jupiter, Mars, Mercury and other interplanetary bodies all on the cards.
We got you, Pluto!
In the long lead-up to our ultimate flyby of Pluto, space science has reconfigured our notions of what it means to be a solar system, a planet, a world.

Photos from the spacecraft's close approach are dazzling. They and other data from the mission will fill in some of the blanks about Pluto and provide a snapshot of the infant solar system.
Pluto’s enigmatic companion Charon.
What can the data from New Horizons tell us about the dwarf planet's five moons?
High resolution view of a 300 km wide region of Pluto. But where are the impact craters?
Lack of impact craters intrigues space experts who say it suggests the dwarf planet may be geologically active.
Artist’s impression Pluto and it’s largest satellite Charon. Is this how the dwarf planet will look as New Horizons swings past?
Pluto is one of the most enigmatic objects in our solar system, and its secrets are soon to be uncovered by the New Horizons probe.
An artist’s concept of a plume of water vapour thought to be ejected off the surface of Europa. Could life be beneath?
Jupiter's moon Europa is one of the most enticing objects in our solar system, and a future NASA mission may help reveal whether it is a suitable for life.
What mysteries lie beneath your icy crust, Europa?
NASA has now formally started to pack its bags for the next big discovery mission, this time heading to Jupiter’s icy moon Europa. Last month NASA announced the instruments that will fly on this trip and…
