A LOOK AT GALAXY NGC 4485

FROM:  NASA

This image from NASA/ESA's Hubble Space Telescope shows galaxy NGC 4485 in the constellation of Canes Venatici (The Hunting Dogs). The galaxy is irregular in shape, but it hasn’t always been so. Part of NGC 4485 has been dragged towards a second galaxy, named NGC 4490 — which lies out of frame to the bottom right of this image. Between them, these two galaxies make up a galaxy pair called Arp 269. Their interactions have warped them both, turning them from spiral galaxies into irregular ones. NGC 4485 is the smaller galaxy in this pair, which provides a fantastic real-world example for astronomers to compare to their computer models of galactic collisions. The most intense interaction between these two galaxies is all but over; they have made their closest approach and are now separating. The trail of bright stars and knotty orange clumps that we see here extending out from NGC 4485 is all that connects them — a trail that spans some 24 000 light-years. Many of the stars in this connecting trail could never have existed without the galaxies’ fleeting romance. When galaxies interact hydrogen gas is shared between them, triggering intense bursts of star formation. The orange knots of light in this image are examples of such regions, clouded with gas and dust. European Space Agency Credit: ESA/Hubble & NASA, Acknowledgement: Kathy van Pelt.

THE PATH TO MARS AND BEYOND

FROM:  NASA

NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010.  A fleet of robotic spacecraft and rovers already are on and around Mars, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back radiation data from the surface. This data will help us plan how to protect the astronauts who will explore Mars. Future missions like the Mars 2020 rover, seeking signs of past life, also will demonstrate new technologies that could help astronauts survive on Mars.  Engineers and scientists around the country are working hard to develop the technologies astronauts will use to one day live and work on Mars, and safely return home from the next giant leap for humanity.  Illustration from Nasa.

THE ARM OF ATLANTIS MOVES DESTINY

FROM:  NASA 

On Feb. 10, 2001, the crews of the Space Shuttle Atlantis and the International Space Station successfully installed the U.S. Destiny Laboratory onto the station. In this photo, Destiny is moved by the shuttle's remote manipulator system (RMS) robot arm from its stowage position in the cargo bay of the Space Shuttle Atlantis. Astronaut Marsha Ivins began the work, using Atlantis' robotic arm to remove a station docking port, called Pressurized Mating Adapter 2 (PMA 2), to make room for Destiny. The adapter was removed from the station's Unity module and latched in a temporary position on the station's truss. Then, at 9:50 a.m. CST, astronauts Tom Jones and Bob Curbeam began a spacewalk that continued throughout the day, in tandem with Ivin's robotic arm work. Jones provided Ivins visual cues as she moved the adapter to its temporary position, and Curbeam removed protective launch covers and disconnected power and cooling cables between the Destiny lab and Atlantis. At 12:57 p.m., the lab was latched into position on the station, and soon a set of automatic bolts tightened to hold it permanently in place for years of space research. The lab added 3,800 cubic feet of volume to the station, increasing the onboard living space by 41 percent. The 2005 NASA Authorization Act designated the U.S segment of the space station as a national laboratory. As the nation's only national laboratory on-orbit, the space station National Lab will improve life on Earth, foster relationships among NASA, other federal entities, and the private sector, and advance science, technology, engineering and mathematics (STEM) education through utilization of the space station's unique capabilities as a permanent microgravity platform with exposure to the space environment.  Image Credit: NASA.

WHERE THE WATER MEETS THE LAND IN THE WESTERN SAHARA

FROM:  NASA 

On May 23, 2014, Expedition 40 Commander Steve Swanson posted this photograph -- taken from the International Space Station -- to Instagram. Swanson noted, “Western Sahara – the contrast between the sand and the water is spectacular from here.” Swanson uploaded the first image from space to Instagram on April 7. He began posting imagery to the social media site during his pre-flight training. › View Instagram imagery from the International Space Station The three Expedition 40 crew members aboard the International Space Station worked advanced science this week while awaiting a new trio, set to lift off on Wednesday, May 28. Soyuz Commander and cosmonaut Maxim Suraev, NASA astronaut Reid Wiseman and European astronaut Alexander Gerst will launch aboard the Soyuz TMA-13M spacecraft at 3:57 p.m. EDT (1:57 a.m. May 29 Baikonur time) from the Baikonur Cosmodrome.
