NuStar Headed To The Stars
NASA‘s Nuclear Spectroscopic Teelscope Array, or NuSTAR, is now perched atop its Pegasus XL rocket, strapped to the plane that will carry the mission to an airborne launch. Launch is scheduled for June 13, no earlier than 8:30 a.m. PDT (11:30 a.m. EDT).
The plane — the L-1011 “Stargazer” aircraft — is now at Vandenberg Air Force Base in central California. It is scheduled to fly to Kwajalein Atoll in the central Pacific Ocean from June 5 to 6. About an hour before launch, the plane will lift off from the island, and drop NuSTAR and its rocket over the ocean. The rocket will then ignite, carrying NuSTAR to its final orbit around Earth’s equator.

NuSTAR will be the first space telescope to create sharp images of X-rays with high energies, similar to those used by doctors and dentists. It will conduct a census for black holes, map radioactive material in young supernovae remnants, and study the origins of cosmic rays and extreme physics around collapsed stars.

NuSTAR is a Small Explorer mission led by the California Institute of Technology in Pasadena and managed by NASA’s Jet Propulsion Laboratory, also in Pasadena, for NASA’s Science Mission Directorate in Washington. The spacecraft was built by Orbital Sciences Corporation, Dulles, Va. Launch management and government oversight for the mission is the responsibility of NASA’s Launch Services Program at the Kennedy Space Center in Florida.

NASA'S PEGASUS

Pegasus Fairing Removed
Orbital Sciences’ Pegasus XL rocket is viewed over the Pegasus payload fairing, positioned part in and part out of the environmental enclosure in Orbital’s hangar on Vandenberg Air Force Base in California. Half of the Pegasus fairing has been removed from around NASA’s NuSTAR spacecraft. Access to the spacecraft is needed for compatibility testing to verify communication with a tracking station in Hawaii.

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.
