... Then in 1959 the National Aeronautics and Space Administration asked the United States military services to list their members who met specific qualifications. The search was underway for pilots for the exciting new manned space flight program. In seeking its first space pilots, NASA emphasized jet aircraft flight experience and engineering training, and it tailored physical stature requirements to the small cabin space available in the Mercury capsule then being designed. ...

Information about this camera is below . ... Yes , I did in fact put on the web one of the earliest web cameras ever. I can document the software as early as May 1994 (based both on backup tapes, as well as the May 1994 annular eclipse which we imaged using one of these cameras), although I'm sure I had things working over the winter before that. I can't remember if my inspiration was that someone else put a camera on the web, or that someone else had a camera on the Mbone in their office. ...

... One possible application of a solar sail is a spacecraft to warn Earth of approaching interplanetary disturbances and shocks. ... Spacecraft that can provide such a warning are currently stationed at (or near) the Lagrangian L1 point , between the Earth and the Sun--at about 4 times the distance of the moon and 1/100 times that of the Sun. ... Because of the greater distance from Earth, the Earth's pull there is weaker, not enough to make the spacecraft match the Earth's motion around the Sun. ...

This month's Geminid meteor shower is expected to peak around the late evening of Tuesday 13th/early hours of Wednesday 14th. The shower is usually one of the best of the annual meteor showers, with many relatively bright, slow- to medium-speed fireballs. ... These meteors are believed to originate from the near-Earth asteroid, Phaethon, discovered by a NASA satellite in 1983. ...

... Assured of a reliable method of solving the normal equations, we now consider the equations of condition. The observed magnitude m of a star at M air masses with true instrumental magnitude is modelled as ([ 10 ], [ 28 ]) . ... The effective extinction coefficient depends on the effective spectral gradient [ 29 ] of the star, for which we use some color index, affected by half the atmospheric reddening ([ 26 ], [ 10 ]): . ... Thus, for the B band of UBV, we use the (U-V) color. ...

... Previous: Determination of Variable Time Delay in Uneven Data Sets . ... It is shown that the likeness of the periodogram and the LS-spectrum (both estimators of the power spectrum are widely used in the spectral analysis of time series), depends on the properties of the spectral window corresponding to the distribution of time points. ... Present day theory and practice of the spectral analysis of unequally spaced time series are based on two approaches. ...
