Satellite to Study ''Space Weather''
The National Aeronautics and Space Administration soon will launch another Explorer satellite to unravel some of the scientific mysteries of how "space weather" affects man's daily life and his future exploration of space. The 89-pound satellite, S-3a, similar to the highly successful Explorer XII placed into orbit last year, will be launched from Cape Canaveral, Fla., no earlier than October 2, using a Thor-Delta rocket. If successful, this will be the 12th straight launch f o r the Delta continuing its unprecedented record for U.S. rocketry.

Far-ultraviolet absorption spectra of quasars: How to find missing hot gas and metals
We show that some high-redshift QSO absorption systems that reveal only the H I Lyman series lines at wavelengths visible from the ground maybe a new class of ultra-high-ionization metal line systems, with metal lines in the far-UV region which is now being explored with satellites. At high temperatures or in intense radiation fields metal systems will not show the usual C IV absorption, and O VI will become the most prominent metal absorber. At still higher ionization, O IV also becomes weak and the strongest metal lines are from Ne VIII, Mg X and Si XII, which have doublets in the rangs 500-800 A. Hence very high ionization metal systems will not show metal lines in existing spectra. Recent X-ray observations show that galaxy halos contain hot gas, so we predict that far-UV spectra of QSOs will also show this gas.
