Tragedy: Challenger exploded shortly after launch from the Kennedy Space Centre.
We should honour the dead by striving to go further.
No warp drives or worm holes required.

Four decades later, I find myself surveying 13 billion years of cosmic history and mapping events that really did happen a long time ago in galaxies far, far away.
Space is now big business. But is that good – or bad – news for NASA?
Hyperspace may one day be a reality.
Many people think relativity puts a hard speed limit on the universe, but it actually opens up the possibility of faster-than-light travel - if we can overcome some significant practical hurdles.
Humans didn’t evolve to deal with the unique conditions of space travel.
Hollywood may already have done it but when we eventually send real astronauts to Mars, what medicines should we arm them with? And will they work the same way as they do on Earth?
Five science (fiction) reasons why you should get to know Doctor Who.
Andreas Mogensen, Aidyn Aimbetov and Gennady Padalka rest outside their spacecraft and are surrounded by support personnel after landing.
Gennady Padalka has returned to Earth from the International Space Station. He has broken the record for time in space and will be the first person on Earth to have eaten salad grown in space.
Reported "evidence" that the proposed fuel-free "EmDrive" works (and breaks the known laws of physics) is nothing of the sort.
Padalka might be keeping fit but we simply don’t know what effect repeated space travel can have on our bodies.
Russian cosmonaut Gennady Padalka should think twice before attempting to spend another thouands days in space.

The turbocharged capitalism of private space flight is strangely at odds with the brotherly, generous global consensus that built the legal framework for extra-terrestrial travel.
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.
I can get you there fast!
There's a cosmic speed limit that unfortunately means you aren't going to be firing up warp drive anytime soon.
I really hope this is the right flag.
Radiation in space could lead to cognitive decline.
“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.
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.
H G Wells’s Martians.
Literature has long imagined other worlds but now space travel and planetary colonisation look to become scientific fact.
Is this how space travel will look some day? ‘Sulu, punch it!’
Some climatologists argue it may be too late to reverse climate change, and it’s just a matter of time before the Earth becomes uninhabitable – if hundreds of years from now. The recent movie Interstellar…
The next generation of manned-space flight: Orion.
Generations of mariners have spent time anxiously watching the weather, waiting for the right conditions. It seems that despite all the high-tech advances we’ve made, spacecraft are still subject to the…

Last week was a particularly grim one for private space flights. Virgin Galactic’s SpaceShipTwo crashed in the Mojave Desert, about 150km north of Los Angeles, killing a pilot, Michael Alsbury, and seriously…
