The nose cone of the space shuttle Endeavour is seen next to the Randy’s Donuts landmark in Inglewood, California, Friday, Oct. 12, 2012. Endeavour, built as a replacement for space shuttle Challenger, completed 25 missions, spent 299 days in orbit, and orbited Earth 4,671 times while traveling 122,883,151 miles. Beginning Oct. 30, the shuttle will be on display in the CSC’s Samuel Oschin Space Shuttle Endeavour Display Pavilion, embarking on its new mission to commemorate past achievements in space and educate and inspire future generations of explorers.

NASA's Low-Density Supersonic Decelerator (LDSD) hangs from a launch tower at U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii. The saucer-shaped vehicle will test two devices for landing heavy payloads on Mars: an inflatable donut-shaped device and a supersonic parachute. The launch tower helps link the vehicle to a balloon; once the balloon floats up, the vehicle is released from the tower and the balloon carries it to high altitudes. The vehicle's rocket takes it to even higher altitudes, to the top of the stratosphere, where the supersonic test begins. http://photojournal.jpl.nasa.gov/catalog/PIA19342

NASA's Van Allen Probes Spot an Impenetrable Barrier in Space
JSC2000-E-22286 (8 September 2000) --- An overall shot in Houston's Mission Control Center (MCC) shows flight controllers awaiting the launch of the Space Shuttle Atlantis from the Kennedy Space Center (KSC) in Florida. The vehicle later launched on schedule, at 8:46 a.m. (EDT), September 8, 2000, as the Johnson Space Center (JSC) flight control team took the baton from KSC's launch controllers. According to flight director Bill Reeves, "The picture referenced was taken less than an hour before launch for STS-106, before we changed the front screens for ascent operations. Wayne Hale (in glasses) is the Flight director for ascent and LeRoy Cain seated to his left was serving as "Weather Flight" for Wayne. The console in the front right corner of the room next to the screens is the Ground Control position, where I was supporting at this time. The man with white hair is Norn Talbott, who will be retiring after this flight with more than 35 years at NASA. Ray Grossman is next to him, who is training to take his place on the GC Ascent Team. I am in fron of and slightly to the right of Ray. As you can see by the boxes at the consoel behind us (Mechanical), we come well prepared for all contingencies, including donuts for early morning shifts. We were on console by 2:00 am central time for the 7:45 am launch." Reference: https://spaceflight.nasa.gov/feedback/expert/answer/mcc/sts-106/09_14_09_35_19.html

The team for NASA's BARREL – short for Balloon Array for Radiation belt Relativistic Electron Losses -- mission returned from Antarctica in March 2014. BARREL's job is to help unravel the mysterious Van Allen belts, two gigantic donuts of radiation that surround Earth, which can shrink and swell in response to incoming energy and particles from the sun and sometimes expose satellites to harsh radiation. While in Antarctica, the team launched 20 balloons carrying instruments that sense charged particles that are scattered into the atmosphere from the belts, spiraling down the magnetic fields near the South Pole. Each balloon traveled around the pole for up to three weeks. The team will coordinate the BARREL data with observations from NASA's two Van Allen Probes to better understand how occurrences in the belts relate to bursts of particles funneling down toward Earth. BARREL team members will be on hand at the USA Science and Engineering Festival in DC on April 26 and 27, 2014 for the exhibit Space Balloons: Exploring the Extremes of Space Weather. <b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b><b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

Ballooning in the constant sun of the South Pole summer
This composite picture is a seamless blend of ultra-sharp NASA Hubble Space Telescope (HST) images combined with the wide view of the Mosaic Camera on the National Science Foundation's 0.9-meter telescope at Kitt Peak National Observatory, part of the National Optical Astronomy Observatory, near Tucson, Ariz. Astronomers at the Space Telescope Science Institute assembled these images into a mosaic. The mosaic was then blended with a wider photograph taken by the Mosaic Camera. The image shows a fine web of filamentary "bicycle-spoke" features embedded in the colorful red and blue gas ring, which is one of the nearest planetary nebulae to Earth. Because the nebula is nearby, it appears as nearly one-half the diameter of the full Moon. This required HST astronomers to take several exposures with the Advanced Camera for Surveys to capture most of the Helix. HST views were then blended with a wider photo taken by the Mosaic Camera. The portrait offers a dizzying look down what is actually a trillion-mile-long tunnel of glowing gases. The fluorescing tube is pointed nearly directly at Earth, so it looks more like a bubble than a cylinder. A forest of thousands of comet-like filaments, embedded along the inner rim of the nebula, points back toward the central star, which is a small, super-hot white dwarf. The tentacles formed when a hot "stellar wind" of gas plowed into colder shells of dust and gas ejected previously by the doomed star. Ground-based telescopes have seen these comet-like filaments for decades, but never before in such detail. The filaments may actually lie in a disk encircling the hot star, like a collar. The radiant tie-die colors correspond to glowing oxygen (blue) and hydrogen and nitrogen (red). Valuable Hubble observing time became available during the November 2002 Leonid meteor storm. To protect the spacecraft, including HST's precise mirror, controllers turned the aft end into the direction of the meteor stream for about half a day. Fortunately, the Helix Nebula was almost exactly in the opposite direction of the meteor stream, so Hubble used nine orbits to photograph the nebula while it waited out the storm. To capture the sprawling nebula, Hubble had to take nine separate snapshots. Planetary nebulae like the Helix are sculpted late in a Sun-like star's life by a torrential gush of gases escaping from the dying star. They have nothing to do with planet formation, but got their name because they look like planetary disks when viewed through a small telescope. With higher magnification, the classic "donut-hole" in the middle of a planetary nebula can be resolved. Based on the nebula's distance of 650 light-years, its angular size corresponds to a huge ring with a diameter of nearly 3 light-years. That's approximately three-quarters of the distance between our Sun and the nearest star. The Helix Nebula is a popular target of amateur astronomers and can be seen with binoculars as a ghostly, greenish cloud in the constellation Aquarius. Larger amateur telescopes can resolve the ring-shaped nebula, but only the largest ground-based telescopes can resolve the radial streaks. After careful analysis, astronomers concluded the nebula really isn't a bubble, but is a cylinder that happens to be pointed toward Earth. http://photojournal.jpl.nasa.gov/catalog/PIA18164
