In 1974, Mike Thomas was making five-meg disk packs - the biggest in the world, at the time. But IBM, Burroughs, Honeywell and other major computer makers said no one would ever need that much storage. In 1989, Bill Gates said a PC would never need more than 256 kbytes of cache memory and 40 megabytes of hard drive storage. And yet today's PC has on average 64 megabytes of cache and 20 to 60 gigabyte hard drives. In short, Thomas predicted the need for mega storage systems in 1974, and he's still at it. In fact, as far as he's concerned, the need isn't diminishing - it's increasing.
An asteroid the size of a small office building will make the closest approach ever recorded to the Earth on Thursday evening
Discovered just two days ago by an automated telescope scanning the sky for near-Earth objects, asteroid 2004 FH will miss the planet by a mere 40,000 kilometres, just over a tenth of the distance to the Moon.
Pluto's title as the outermost planet could be in jeopardy, with the discovery of a large object orbiting the Sun far further out than any other.
The object, dubbed Sedna for the Inuit goddess of the sea, lies about 10 billion miles from the Sun, nearly twice as far as Pluto. Its estimated 2000-kilometre diameter is about 90 per cent the size of Pluto's, making Sedna the largest Solar System object discovered since Pluto itself in 1930.
Just days after revealing clear evidence that liquid water was once present at one rover's landing site on Mars, NASA scientists have reported the same at the other, halfway round the planet.
The signs found in a rock examined by Spirit point to a much smaller amount of water than the "soaking" amounts indicated by Opportunity, said deputy mission scientist Ray Arvidson, of Washington University in St Louis, Missouri.
NASA scientists believe they are days away from concluding whether or not Mars once had water using data from the Mars rover Opportunity, they revealed on Thursday.
Opportunity, which has been roaming inside a 20-metre crater on a plateau called Meridiani Planum for nearly five weeks, has been focusing its attention for the past three on a 30-metre outcrop of bedrock and its immediate environs. It has taken microscopic images and spectroscope data and ground portions of the rock surface to peer beneath its coating of dust.
