NASA Selects U.S. Small Business Technology Transfer Projects for Further Development.
An artist's rendition of the 2007 Phoenix Mars probe during landing depicts dust particles stirred up from thrusters. CFD Research Corporation, in conjunction with the University of Florida, received a NASA 2012 STTR Phase II award to further develop a debris simulation tool that will predict the flow of granular materials in spacecraft landings similar. Debris attains high velocities and can damage both the vehicle and landing site. The simulation tool will be useful in helping design landing engine architectures that would minimize this effect in future missions.
Americká meteorologická družice zahajuje nekontrolovatelný pád z oběžné dráhy.
Přibližně do tří let by měla v zemské atmosféře zaniknout družice TRMM, která již dlouhá léta studuje z vesmíru tropické bouře a hurikány. Některé její zbytky přitom mohou dopadnout neznámo kam na zemský povrch. NASA se před lety vzdala možnosti družici řízeně zničit daleko od lidí kvůli pokračování její kriticky důležité mise.
Emise CCl4, sloučeniny, která poškozuje ozonovou vrstvu přetrvává, ukazuje výzkum NASA.
Satelity pozorovaly největší ozonovou díru nad Antarktidou v roce 2006, fialová a modrá představují oblasti s nízkou koncentrací ozonu v atmosféře; žlutá a červená jsou oblasti o vyšších koncentracích.
NASA dokončila úspěšné sérii testů kompozitní kryogenní nádrže.
Jedna z největších kompozitních kryogenních nádrží, která byla nedávno postavena, dokončila sérii testů v Marshall Space Flight Center, NASA v Huntsville, Alabama. Nádrž byla testována na zkušebním stavu, kde byla naplněna kapalným vodíkem se simulací namáhání nádrže které by mohlo nastat během startu.
NASA Completes Key Review of World’s Most Powerful Rocket in Support of Journey to Mars.
Artist concept of NASA’s Space Launch System (SLS) 70-metric-ton configuration launching to space. SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and ultimately to Mars.
This artist concept shows NASA’s Space Launch System, or SLS, rolling to a launchpad at Kennedy Space Center at night. SLS will be the most powerful rocket in history, and the flexible, evolvable design of this advanced, heavy-lift launch vehicle will meet a variety of crew and cargo mission needs.
Nejhorsi je opetne pouziti pridavnych raket na pevne palivo. Asi se STS Chalengrem nepoucili. I kdyz maji LAS, bezpecnejsi je okamzite zastavit privod tekuteho paliva do motoru. Nevim jak chteji zastavit pevne palivo.
SLS v teto podobe je kravina. Nosic 70t pro malou kapsli? Na to by mel stacit samotny nosic bez pridavnych raket na pevne palivo. Leda kdyz by za kapsli byl habitat, ktery by si to vytahlo jako LEM u S5.
Zkratka se nepoucili, na kapsli s posadkou pouzit malou bezpecnou levnou raketu a pro naklad klidne i ten booster na pevne palivo. Pouzivat jeden typ nosice pro posadku a naklad je kravina.
citace:Nosic 70t pro malou kapsli? Na to by mel stacit samotny nosic bez pridavnych raket na pevne palivo.
Těch 70 tun nosnosti SLS je včetně plně natankovaného stupně "Interim Cryogenic Propulsion Stage" pro odlet k Měsíci a plně natankovaného služebního modulu SM.
Pro porovnání, na raketě Delta IV Heavy letos v prosinci bude na nízké oběžné dráze stejný stupeň ICPS už poloprázdný, takže vynese Orion (CM+SM) jen do apogea 6.000 km (přesto, že maketa SM bude velmi lehká - bez paliva a bez motoru). Dokonce i LAS bude inertní, bez paliva.
NASA's Spitzer Telescope Witnesses Asteroid Smashup.
This artist’s concept shows the immediate aftermath of a large asteroid impact around NGC 2547-ID8, a 35-million-year-old sun-like star. NASA's Spitzer Space Telescope witnessed a giant surge in dust around the star, likely the result of two asteroids colliding.
Astronomers were surprised to see these data from NASA's Spitzer Space Telescope in January 2013, showing a huge eruption of dust around a star called NGC 2547-ID8. In this plot, infrared brightness is represented on the vertical axis, and time on the horizontal axis.
Sparks Fly as NASA Pushes the Limits of 3-D Printing Technology.
Engineers just completed hot-fire testing with two 3-D printed rocket injectors. Certain features of the rocket components were designed to increase rocket engine performance. The injector mixed liquid oxygen and gaseous hydrogen together, which combusted at temperatures over 6,000 degrees Fahrenheit, producing more than 20,000 pounds of thrust.
NASA Probes Studying Earth’s Radiation Belts to Celebrate Two Year Anniversary.
This image was created using data from the Relativistic Electron-Proton Telescopes on NASA's twin Van Allen Probes. It shows the emergence of a new third transient radiation belt. The new belt is seen as the middle orange and red arc of the three seen on each side of the Earth.

NASA Announces Student-focused Experiment Program Awards.
The International Space Station Program Science Office has announced the award recipients for the International Space Station Post-Graduate Innovation Awards in Space Life and Physical Science Research opportunity. The NASA Research Announcement was targeted at reaching graduate students and post-doctoral fellows who were already starting a career as science researchers in the Life and Physical Sciences disciplines. Proposals included innovative ideas for microgravity research specifically in the areas of physical sciences, microbiology and space physiology.
NASA Research Aids Response to Earthquake in California's Napa Valley.
Data collected five days after the magnitude 6.0 Napa earthquake on Aug. 24 determined that the earthquake surface rupture was complex, with multiple fault offsets near the quake epicenter. Each colored contour in the image represents about 12 centimeters of ground displacement.
A strain magnitude map of the Aug. 24, 2014 Napa California quake, developed under NASA's E-DECIDER disaster decision support system. The map, which highlights areas where the greatest ground deformation has occurred based on a fault model, was given to state officials to assist response efforts.
NASA, Italian Space Agency (ASI) and university scientists analyzed radar images from ASI's COSMO-SkyMed satellites to calculate Earth surface deformation from the Napa quake. The colors show how much permanent surface movement occurred during the one-month interval between two satellite images.
NASA's C-20A Earth science aircraft carrying the UAVSAR pod lifts off the runway at Edwards Air Force Base. The eight-foot-long pod houses the sophisticated L-band synthetic aperture radar that was able to measure fault offsets from the Napa Valley earthquake.
