  • July 23, 1999, Chandra X-ray Observatory Awaits Deployment

    23 Jul 2015 | 8:52 am
    This 70mm frame shows the 50,162-pound Chandra X-ray Observatory before it was tilted upward for its release from the Space Shuttle Columbia's payload bay on July 23, 1999, just a few hours following the shuttle's arrival in Earth orbit. Chandra was spring-ejected from a cradle in the payload bay at 6:47 a.m. Central time.
  • Stellar Sparklers That Last

  • NASA Telescopes Set Limits On Spacetime Quantum "Foam"

    28 May 2015 | 7:29 am
    A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the quantum nature, or “foaminess” of spacetime at extremely tiny scales.

    New NASA STI

  • Constraints on Vesta's Interior Structure Using Gravity and Shape Models from the Dawn Mission

    28 Aug 2015 | 8:28 am
    Abstract: We use the shape and gravity field of Vesta determined from observations of the Dawn spacecraft to place constraints on the asteroid's interior structure. We compute a three-layer interior structure model by minimizing the power of the residual gravity anomaly. The densities of the mantle and crust are based on constraints derived from the Howardite-Eucrite-Diogenite (HED) meteorites. Vesta's present-day shape is not in hydrostatic equilibrium. The Rheasilvia and Veneneia impact basins have a...
  • Quantifying Evapotranspiration from Urban Green Roofs: A Comparison of Chamber Measurements with Commonly Used Predictive Methods

    28 Aug 2015 | 8:18 am
    Abstract: Quantifying green roof evapotranspiration (ET) in urban climates is important for assessing environmental benefits, including stormwater runoff attenuation and urban heat island mitigation. In this study, a dynamic chamber method was developed to quantify ET on two extensive green roofs located in New York City, NY. Hourly chamber measurements taken from July 2009 to December 2009 and April 2012 to October 2013 illustrate both diurnal and seasonal variations in ET. Observed monthly total ET d...
  • TankSIM: A Cryogenic Tank Performance Prediction Program

  • An HST COS "SNAPshot" Spectrum of the K-Supergiant (Lambda)Vel (K4Ib-II)

    28 Aug 2015 | 5:48 am
    Abstract: We present a far-ultraviolet spectrum of the K4 Ib-II supergiant (Lambda)Vel obtained with the Hubble Space Telescope's Cosmic Origins Spectrograph (COS) as a part of the SNAPshot program "SNAPing coronal iron" (GO 11687). The observation covers a wavelength region (1326-1467 A) not previously recorded for (Lambda)Vel at a spectral resolving power of R approx. 20,000 and displays strong emission and absorption features, superposed on a bright chromospheric continuum. Fluorescent excitation is...
  • Challenges in Measuring External Currents Driven by the Solar Wind-Magnetosphere Interaction

    28 Aug 2015 | 5:18 am
    Abstract: In studying the Earth's geomagnetism, it has always been a challenge to separate magnetic fields from external currents originating from the ionosphere and magnetosphere. While the internal magnetic field changes very slowly in time scales of years and more, the ionospheric and magnetospheric current systems driven by the solar wind -magnetosphere interaction are very dynamic. They are intimately controlled by the ionospheric electrodynamics and ionospheremagnetosphere coupling. Single spacec...

The absence of a significant gravitational force facilitates observation of such motions as controlled by interfacial and capillary forces. Two experimental configurations were used. One deals with the liquid on one solid surface, and the other with the liquid between a pair of closed spaced surfaces. Time sequence photographs of fluid moti...
