    Satellites See Oklahoma Tornado Storm System

    05.21.13 - 
    On May 20, 2013, NASA and NOAA satellites observed the system that generated severe weather in the south central United States and spawned the Moore, Okla., tornado. Before, during and after the tornado, satellites provided imagery and data to forecasters. NOAA's GOES-13 satellite provided forecasters with images of the storm system every 15 minutes.

    NASA and the White House Pay Tribute to Sally Ride

    05.08.13 - 
    NASA and President Obama are honoring the life and legacy of Sally Ride on the day a national tribute was held for the first American woman in space. The president announced Monday afternoon Ride will be posthumously awarded the Presidential Medal of Freedom during a ceremony at the White House later this year. Monday night, NASA further paid tribute to Ride by creating a new agency internship program in her name and renaming a science instrument aboard the International Space Station.

    Forecast for Titan: Wild Weather Could Be Ahead

    05.21.13 - 
    Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, waves could ripple across the moon's hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA's Cassini spacecraft.

    Asteroid Sample Return Mission Into Development

    05.16.13 - 
    NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.

    The Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) passed a confirmation review Wednesday called Key Decision Point (KDP)-C. NASA officials reviewed a series of detailed project assessments and authorized the spacecraft's continuation into the development phase.

    Scientists Investigate Engine Ice Crystal Icing

    05.17.13 - 
    How does ice accumulate inside hot turbofan jet engines during flight? NASA scientists at the Glenn Research Center, working with engine manufacturers, are closer to answering that question thanks to the only test facility in the world capable of creating a high altitude ice crystal cloud during a full-scale engine test.

    SNC Dream Chaser Testing Begins

    05.15.13 - 
    Sierra Nevada Corporation's (SNC) Space Systems Dream Chaser flight vehicle arrived at NASA's Dryden Flight Research Center in Edwards, Calif., Wednesday to begin tests of its flight and runway landing systems.

    The overall goal of CCP is to achieve safe, reliable and cost-effective U.S. human access to and from the International Space Station and low-Earth orbit.

  • Kepler Mission Manager Update

    Kepler Mission Manager Update

    05.15.13 - 
    During the semi-weekly contact on Tuesday, May 14, 2013, the Kepler spacecraft was once again in safe mode. As was the case earlier this month, this was a Thruster-Controlled Safe Mode. The root cause is not yet known, however the proximate cause appears to be an attitude error. The spacecraft was oriented with the solar panels facing the sun, slowly spinning about the sun-line.

    The communication link comes and goes as the spacecraft spins.

    Nancy Grace Roman Celebrates Her Birthday

    05.16.13 - 
    Long before there was a program called Women@NASA, Dr. Nancy Grace Roman was paving the path for women at NASA. She was the first Chief of Astronomy in the Office of Space Science. In her role, she successfully managed numerous astronomy-based projects including the Hubble Space Telescope. At the age of 88, Dr. Roman speaks eloquently and intelligently with a passion to encourage young women to pursue careers in science and engineering.

    Faith 7: Gordon Cooper

    05.13.13 - 
    50 years ago this week, astronaut Gordon Cooper made the final flight of the Mercury program, spending more than a day in orbit in his Faith 7 capsule.

    "Gordo" spent more time in orbit than all of the previous Mercury astronauts combined, and became the first American astronaut to sleep in space.

  • Activity Continues on the Sun

    Activity Continues on the Sun

    05.15.13 - 
    Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT. This flare is classified as an X1.2 flare and it is the 18th X-class flare of the current solar cycle.

    The flare caused a radio blackout – categorized as an R3, or strong, on NOAA’s space weather scales from R1 to R5 -- which has since subsided.
