The images were pieced together from thousands of images taken over many months by the satellite's remote-sensing device Modis, of every square kilometre of the Earth's surface.

The Earth in True Colors
These spectacular images of the Earth are the most true-colour images of the entire world released to date, according to Nasa scientists.
The images were pieced together from thousands of images taken over many months by the satellite's remote-sensing device Modis, of every square kilometre of the Earth's surface.

Pluto's Changing Color
Images taken by the Hubble space telescope show the dwarf planet Pluto, on the edge of our solar system, is redder than it used to be.
From 1954 to 2000, Pluto didn't change in color when it was photographed from Earth. But after that, it did. The red levels increased by 20 percent, maybe up to 30 percent, and stabilized from about 2000 to 2002.
Nasa's scientists believe these are seasonal changes - as the planet heads into a new phase of its 248-year-long seasonal cycle.
The new images are said to show frozen nitrogen brightening in the north and becoming darker in the south.
Flying personal vehicles - not so far away
NASA is working on a personal flying suit. Conceptual designs for the experimental vehicle, called Puffin, were introduced by Mark D. Moore, an aerospace engineer at NASA’s Langley Research Center, at a meeting of the American Helicopter Society on Jan. 20 in San Francisco. The Puffin is designed to be 12 feet in length, with a total wingspan of 14 and a half feet; it would weigh in at 300 pounds (without a pilot).
Are you ready to fly?

Twittering from Space
The NASA astronaut, T.J. Creamer, sent today the first tweet from Space: "Hello Twitterverse! We r now LIVE tweeting from the International Space Station -- the 1st live tweet from Space! :) More soon, send yours".
The new Crew Support LAN, takes advantage of existing communication links to and from the station and gives astronauts the ability to browse and use the Web.
Isn't that amazing? What do you think?

Deal of the Day
NASA has slashed the price of the 1970s-era spaceships to $28.8 million apiece from $42 million. The shuttles are for sale once their flying days are over, which is scheduled to be this fall.
Act now, supplies are limited. ;)
