Radio telescopes on Earth will beam 90,000 messages to Mars on Friday to commemorate the launch 50 years ago of the first robotic probe to visit the planet.
A US space funding company called Uwingu organised the extraterrestrial shout-out to mark the 50th anniversary of NASA's Mariner 4 mission and to raise funds for its other projects.
Ultra-strong graphene's weak spot could be key to fuel cells In a discovery that experts say could revolutionize fuel cell technology, scientists in Britain have found that graphene, the world's thinnest, strongest and most impermeable material, can allow protons to pass through it.
The researchers, led by the Nobel prize winner and discoverer of graphene Andre Geim of Manchester University, said their finding also raised the possibility that, in future, graphene membranes could be used to "sieve" hydrogen gas from the atmosphere to then generate electricity.
