225. Further Analysis of ECOM-721 Data

Author

CALIFORNIA UNIV BERKELEY, Chakrabarti, Supriya, CALIFORNIA UNIV BERKELEY, and Chakrabarti, Supriya

Abstract

During the period between February 1, 1989 and September 30, 1992, the U.S. Army grant, number-DAAL03-89-K-0057, has funded auroral and airglow analysis of the ECOM-721 Extreme Ultraviolet Spectrometer Data. Some of the important work that we accomplished with the support of this grant includes transferring the data to a more accessible storage format, creating a quick look archive, further development of a solar EUV flux model which is crucial to the ECOM airglow analyses, development of a spherical radiative transfer model, and the analysis of atomic nitrogen dayglow as well as proton aurora STP78-1 data.

226. Archival of the ECOM-721 Data

Author

CALIFORNIA UNIV BERKELEY SPACE SCIENCES LAB, Chakrabarti, Supriya, CALIFORNIA UNIV BERKELEY SPACE SCIENCES LAB, and Chakrabarti, Supriya

Abstract

The Army grant, number DAAL03-90-G-0233, has funded the procurement of an erasable optical disk drive and media for the archival of the data taken from the ECOM instrument which flew aboard the P78-1 STP satellite. The data which was previously stored in 1/4 inch magnetic tape format is currently being transferred to a random access optical disk format. Although this is a simple process, it is very important to the ultimate data analysis. With random access to the data and a much smaller volume of storage media, the data will now be accessible for long term studies of the extreme ultraviolet (EUV) and far ultraviolet (FUV) aurora and airglow. About 1100 orbits have been archived, and work is continuing on archiving the rest of the data with support from elsewhere.

227. Export controls stifle science

Author

Chakrabarti, Supriya

Subjects
Export controls -- Evaluation, Arms control -- Evaluation, Outer space -- Discovery and exploration, Outer space -- Evaluation, Government export policy and export regulation, Aerospace and defense industries, Business, Transportation industry
Abstract

The author offers his views of the setbacks that American companies suffered following imposition of the International Traffic in Arms Regulations (ITAR). He suggests steps that should be taken to rejuvenate space research in the U.S. while offering young space scientists and technologists an opportunity to showcase their creativity and innovative designs.
