Space shuttle Endeavour arrived on earth for the final time on Wednesday in a pre-dawn landing as NASA takes the next-to-last step to winding down its shuttle program with Atlantis arriving at the launch pad this morning and set to make its final launch on July 8.

NASA space shuttle Endeavour has landed for the final time at Kennedy Space Center after 248 orbits around Earth and a journey of 6,510,221 miles on STS-134 mission. Endeavour's next 'mission' will be attracting guests to the California Science Center museum in Los Angeles.

NASA has rolled its fourth space-rated space shuttle, OV-104 Atlantis, to launch pad 39A at Kennedy Space Center in Florida, a three-mile trip, ahead of her July 8 mission to the International Space Station.

Endeavour hove into view through the night skies above Kennedy Space Centre just after 0230 EDT (0635 GMT), bringing its six-man crew home after a 16-day mission to deliver a premier science experiment to the International Space Station on NASA's second-to-last shuttle flight.

After a 19-year career and 299 days spent in space, the youngest NASA shuttle Endeavour touched down for the last time at approximately 2:36 am Eastern. It landed at the Kennedy Space Center in Florida.

Space Shuttle Endeavour's flight crew is making final preparations to make a pre-dawn landing in Florida on Wednesday after wrapping up an 11 day stay at the International Space Station.

Recent observations at NASA's Spitzer Space Telescope have revealed astonishing pictures of tiny crystals of a green mineral called olivine which are falling down as rain on a burgeoning star. This has been the first time that such observations have been made in the dusty clouds of gas that collapse around forming stars.

Endeavour is set to make its final return voyage to Earth.

US space shuttle Endeavour undocked from the International Space Station (ISS), Sunday, and began its journey back to earth, marking the end of its 16-day mission of upgrading the orbiting space laboratory.

NASA space shuttle Endeavour has left the International Space Station for the last time late Sunday and is headed home ending nearly two weeks of joint flight. Endeavour's next mission will be attracting guests to the California Science Center museum in Los Angeles.

From May 28- October 9, 2011, art lovers across the world will able to dwell in a different form of creativity as NASA teams up with the Smithsonian to showcase some of the most unique collections in the field of space art.

This morning the astronauts said goodbye to the crew of the International Space Station and sealed the hatch connecting the two vessels.

NASA (National Aeronautics and Space Organization), in a report, said the organization has picked Fibertek, a company from Virginia which deals with high-tech lasers and electro-optics systems mainly for the military and aerospace projects, to design and deliver laser systems that will be used for ICESat-2 (Ice, Cloud, and land Elevation Satellite-2) mission which is scheduled in 2016

Milky Way galaxy, the home galaxy of the Solar System, and of Earth, belongs to a rare subset among the billions that populate the cosmos.

The Endeavour crew completes the final spacewalk on the space shuttle's final mission into space, NASA reports.

The mission is complete. Astronauts on the Endeavour space shuttle has placed the final part of a robotic arm onto the International Space Station. The task was completed after logging in over 1,000 assembly hours. The final completion was 12 years in the making since the project started in December 1998. This marks the last spacewalk and flight for the Endeavour.

In December, NASA held a press conference to announce that a bacteria discovered in a salty California lake appeared to use arsenic in its DNA. But the findings ran into criticism right from the start, and now the journal Science has published the critiques of the work, as well as a response from the team that did the original work.
