NASA Selects Launch Services for ICESat-2 Mission

CAPE CANAVERAL, Fla. -- NASA's Launch Services Program at the agency's Kennedy Space Center in Florida has selected United Launch Services, LLC of Englewood, Colo., to provide Delta II launch services for the Ice, Cloud and Land Elevation Satellite (ICESat)-2 mission, currently scheduled for July 2016.

A firm fixed-price launch service task order has been awarded under the indefinite-delivery, indefinite-quantity NASA Launch Services (NLS) II contract. NASA's total cost to launch ICESat-2 is $96.6 million, including payload processing, integrated services, telemetry, reimbursables and other launch support requirements.

The Delta II rocket will place the ICESat-2 spacecraft into a near-circular Earth polar orbit following liftoff from Space Launch Complex-2 at Vandenberg Air Force Base in California. ICESat-2 is a continuation of the global time series of precision ice topography measurements initiated by the first ICESat mission. ICESat-2 will measure changes in the elevation of the polar ice sheets to understand their contribution to current and future sea-level rise. It also will characterize polar-sea ice thicknesses and global vegetation heights to understand their connections to the Earth system.

Subcontractors performing work for United Launch Services include Pratt & Whitney Rocketdyne of Canoga Park, Calif., Alliant Techsystems, Inc of Magna, Utah and Aerojet of Sacramento, Calif. United Launch Services' United Launch Alliance provides the Delta II and launch services.

NASA's Launch Services Program at Kennedy Space Center is responsible for management of the ICESat-2 launch service acquisition and implementation.

Dragon Prepares to Resupply Station

The Space Exploration Technologies, or SpaceX, Dragon spacecraft stands inside a processing hangar at Cape Canaveral Air Force Station in Florida. Teams had just installed the spacecraft's solar array fairings.

NASA and its international partners are targeting Friday, March 1, as the launch date for the next cargo resupply flight to the International Space Station by SpaceX. Launch is scheduled for 10:10 a.m. EST from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

SpaceX's Dragon capsule will be filled with about 1,200 pounds of supplies for the space station crew and experiments being conducted aboard the orbiting laboratory.

MAGNETIC LOOPS ON THE SUN

FROM: NASA
Flux Ropes on the Sun

This is an image of magnetic loops on the sun, captured by NASA's Solar Dynamics Observatory (SDO). It has been processed to highlight the edges of each loop to make the structure more clear.

A series of loops such as this is known as a flux rope, and these lie at the heart of eruptions on the sun known as coronal mass ejections (CMEs.) This is the first time scientists were able to discern the timing of a flux rope's formation. (Blended 131 Angstrom and 171 Angstrom images of July 19, 2012 flare and CME.)

STAR FLASH

What caused this outburst of V838 Mon? For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before -- supernovas and novas expel matter out into space. Although the V838 Mon flash appears to expel material into space, what is seen in the above image from the Hubble Space Telescope is actually an outwardly moving light echo of the bright flash. In a light echo, light from the flash is reflected by successively more distant rings in the complex array of ambient interstellar dust that already surrounded the star. V838 Mon lies about 20,000 light years away toward the constellation of the unicorn (Monoceros), while the light echo above spans about six light years in diameter. Image Credit: NASA, ESA

THE SPIDERWEB GALAXY

Looking like a spider's web swirled into a spiral, Galaxy IC 342 presents its delicate pattern of dust in this image from NASA's Spitzer Space Telescope. Seen in infrared light, faint starlight gives way to the glowing bright patterns of dust found throughout the galaxy's disk. At a distance of about 10 million light-years, IC 342 is relatively close by galactic standards, however our vantage point places it directly behind the disk of our own Milky Way. The intervening dust makes it difficult to see in visible light, but infrared light penetrates this veil easily. IC 342 belongs to the same group as its even more obscured galactic neighbor, Maffei 2. IC 342 is nearly face-on to our view, giving a clear, top-down view of the structure of its disk. It has a low surface brightness compared to other spirals, indicating a lower density of stars (seen here as a blue haze). Its dust structures show up much more vividly (red). Blue dots are stars closer to us, in our own Milky Way. New stars are forming in the disk at a healthy rate. The very center glows especially brightly in the infrared, highlighting an enormous burst of star formation occurring in this tiny region. To either side of the center, a small bar of dust and gas is helping to fuel this central star formation. Data from Spitzer's infrared array camera are shown in blue (3.6 microns), green (4.5 microns) and red (5.8 and 8.0 microns). Image Credit: NASA/JPL-Caltech

JUMPING TO WARP SPEED

This cockpit view of a hypothetical spacecraft traveling at eight-tenths the speed of light shows the visual distortions that would be experienced at such high speeds. The star field is actually being wrapped toward the front of the craft in addition to being significantly blue-shifted.
