The Hubble Space Telescope has been at the forefront of discoveries in the field of astronomy for more than 20 years. It was the first telescope designed to be serviced in space and the last such servicing mission occurred in May 2009. The question of how much longer this valuable resource can continue to return science data remains. In this paper a detailed analysis of the total dose exposure of electronic parts at the box level is performed using solid angle sectoring/3-dimensional ray trace…

The Hubble Space Telescope
The characteristics and capabilities of the Hubble Space Telescope (HST) are described. The telescope can provide an angular resolution of about 0.1 arcsec, a faint stellar limiting magnitude of…
AE9, AP9 and SPM: New Models for Specifying the Trapped Energetic Particle and Space Plasma Environment
The radiation belts and plasma in the Earth’s magnetosphere pose hazards to satellite systems which restrict design and orbit options with a resultant impact on mission performance and cost. For…
Hubble Space Telescope.
TLDR
The Hubble Space Telescope was the most costly and challenging science technology project managed by the Marshall Space Flight Center (MSFC), and its efforts to overcome management and engineering troubles helped ensure that the Space Telescope became a scientific success.
Proton Flux Anisotropy in Low Earth Orbit
Proton flux anisotropy as a function of altitude in the South Atlantic Anomaly is investigated using data from the Compact Environment Anomaly Sensor (CEASE) flown onboard the tri-service…
A New Proton Model for Low Altitude High Energy Specification
A model of high energy protons for low altitude (below 800 km) mission specification was developed. This model is based on the long duration NOAA measurement series. We used only the highest…
The AE-8 trapped electron model environment
TLDR
The purpose of this report is to complete the documentation, finally, for AE-8 so that users can understand its construction and see the comparison of the model with the new data used, as well as with the AE-4 model.

Problems with models of the radiation belts
The current standard models of the radiation-belt environment have many shortcomings, not the least of which is their extreme age. Most of the data used for them were acquired in the 1960's and early…
Space Environments and Effects: Trapped Proton Model
TLDR
An improved model of the Earth's trapped proton environment has been developed that determines the omnidirectional flux of protons with energy between 1 and 100 MeV throughout near-Earth space.
