William Shatner, the actor who played Captain James T. Kirk on the original Star Trek television series, provided a special message to the crew of space shuttle Discovery during the 3:23 am EST wakeup call on Mon., Mar. 7. As Alexander Courage's "Star Trek" theme song played underneath, Shatner replaced the original television introduction with, "Space, the final frontier. These have been the voyages of the Space Shuttle Discovery. Her 30 year mission: To seek out new science. To build new outposts. To bring nations together on the final frontier. To boldly go, and do, what no spacecraft has done before." The "Theme from Star Trek" received the second most votes in a public contest from a Top 40 list for NASA's Song Contest. Shatner recorded the custom introduction for Discovery's final voyage -- its 39th flight and 13th to the International Space Station.

After more than 30 years, the space shuttle era has come to a close. Space shuttle Atlantis and the STS-135 crew landed safely on runway 15 at 5:57 am EDT at Kennedy Space Center's Shuttle Landing Facility in Florida, ending a 13-day journey of more than five million miles. It was the final and 133rd landing in shuttle history. The STS-135 crew consisted of Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandra Magnus and Rex Walheim.

The Hubble Space Telescope presented astronomers with this rosy picture on the celebration of its completion of 21 years since it was deployed in 1990. This especially photogenic group of interacting galaxies called Arp 273 lies in the constellation Andromeda and is roughly 300 million light-years away from Earth. The larger of the spiral galaxies, known as UGC 1810, has a disk that is distorted into a rose-like shape by the gravitational pull of the companion galaxy below it, known as UGC 1813. A swath of blue jewels across the top is the combined light from clusters of intensely bright and hot young blue stars. These massive stars glow fiercely in ultraviolet light. Arp 273 The interaction was imaged on December 17, 2010, with Hubble's Wide Field Camera 3. Hubble was deployed by the STS-31 crew of space shuttle Discovery on April 25, 1990.

Scientists working with NASA's Dawn spacecraft have created a new video showing the giant asteroid Vesta as the spacecraft approaches this unexplored world in the main asteroid belt. The images show a dark feature near Vesta's equator moving from left to right across the field of view as Vesta rotates. It is roughly 60 miles (100 kilometers) in diameter. Vesta's jagged, irregular shape is also seen, hinting at the enormous crater known to exist at Vesta's south pole. The video loops 20 images obtained by Dawn for navigation purposes on June 1, 2011.

Flight Day 6 was kick-started for the STS-135 astronauts with a special wake-up message from Elton John and one of the legendary performer's greatest hits. "Rocket Man" debuted around the time of the Apollo 16 mission, which sent men to the moon for the fifth time. The 4-½ minute song, which describes a long-term space bound astronaut's mixed feelings at leaving his family to do his job, has been played to awaken four shuttle crews aboard Discovery and Atlantis. "Rocket Man" also, one of NASA's top 40 wakeup call songs listed for voter selection during a contest to commemorate the Space Shuttle Discovery and Endeavour's last missions, earned nearly 5000 votes from the public. "Good morning Atlantis, this is Elton John. We wish you much success on your mission. A huge thank you to all the men and women at NASA who worked on the shuttle for the last three decades."
