NASA Extends Contract for Mission, Crew Operations Support

June 26, 2012 Leave a comment

NASA has awarded a contract extension to United Space Alliance of Houston to provide mission and flight crew operations support for the International Space Station and future human space exploration.
The $17.4 million extension of the Integrated Mission Operations Contract covers ground-based human spaceflight operations capability development and execution. This contract includes support for mission planning and preparation, crew and flight controller training, and real-time mission execution.
The initial period of extension runs from Oct. 1, 2012 through Sept. 30, 2013. There is a $17.8 million option to extend the contract for another year effective from Oct. 1, 2013, through Sept. 30, 2014.
The total potential value of the cost-plus-award-fee contract would be $35 million, if the option is exercised. This contract extends the original contract, which was in effect from November 2008 through September 2012.

Multiple Mergers Generate Ultraluminous Infrared Galaxy

June 26, 2012 Leave a comment

A team of astronomers led by Professor Yoshiaki Taniguchi (Ehime University) has concluded that the ultraluminous infrared galaxy (ULIRG) Arp 220 developed from a multiple merger among four or more galaxies. Their new imaging data from the Subaru Telescope and optical spectroscopy from the W. M. Keck Observatory revealed two tidal tails that facilitated their analysis of Arp 220’s development. Because Arp 220 is an archetypal or representative ULIRG, the team’s findings facilitate an understanding of ULIRG development in general.First discovered from the Infrared Astronomical Satellite’s (IRAS) all-sky survey in the mid-1980s, ULIRGs are the most luminous class of galaxies in the relatively near or local Universe. Most of their energy output is in the infrared, suggesting that they contain a large amount of dust, an indication of immense star formation.
