NASA's Long Duration Exposure Facility, or LDEF (pronounced "eldef"), was a cylindrical facility designed to provide long-term experimental data on the outer space environment and its effects on space systems, materials, operations and selected spores' survival.
The NASA Space Radiation Laboratory (NSRL, previously called Booster Applications Facility [3]), is a heavy ion beamline research facility; part of the Collider-Accelerator Department of Brookhaven National Laboratory, located in Upton, New York on Long Island.
The Earth Observing System Data and Information System (EOSDIS) is a key core capability in NASA's Earth Science Data Systems Program. Designed and maintained by Raytheon Intelligence & Space, it is a comprehensive data and information system designed to perform a wide variety of functions in support of a heterogeneous national and international user community.
For instance, a NASA design study for an ambitious large space station envisioned 4 metric tons per square meter of shielding to drop radiation exposure to 2.5 mSv annually (± a factor of 2 uncertainty), less than the tens of millisieverts or more in some populated high natural background radiation areas on Earth, but the sheer mass for that ...
The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers on astronomy and physics, operated for NASA by the Smithsonian Astrophysical Observatory. ADS maintains three bibliographic collections containing over 15 million records, including all arXiv e-prints. [ 1 ]
The Cambridge Atmospheric Chemical Database is a large database in a uniform ASCII format. Each observation is augmented with the meteorological conditions such as temperature, potential temperature, geopotential height, and equivalent PV latitude. GOME data. The NASA Earth Science Project Office archives. The NASA GSFC Distributed Active ...
The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape our understanding of the cosmos.
Thermal radiation enters the instrument through a three-mirror antenna system. The antenna mechanically scans in the vertical plane through the atmospheric limb every 65.5 seconds. The scan covers a height range from the surface up to 90 km (55 miles). Upon entering the instrument, the signal from the antenna is separated into three signals for ...
