Courtesy of NASA's National Space Science Data Center . ... Venera 5 was launched from a Tyazheliy Sputnik (69-001C) towards Venus to obtain atmospheric data. The spacecraft was very similar to Venera 4, although it was of a stronger design. When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During satellite descent towards the surface of Venus, a parachute opened to slow the rate of descent. ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ...

GRANAT is the Russian x-ray sattelite launched to the high apogee orbit (200,000 km) and operated almost for 10 years (1989 -1999) , carrying out four major instruments: French SIGMA coded-mask hard x-ray telescope (30-1000 keV), Soviet ART-P coded-mask telescope (2??-60?? keV), all-sky monitor WATCH (6-150 keV), and a gamma-burst detector PHEBUS . ... Since September 1994, GRANAT is in the survey mode. ... Explore pages devoted to individual GRANAT instruments (including main scientific results): . ...

This diagram illustrates the effects of absolutely positioning a box with respect to the initial containing block. ... Most of the "inner" box contents are therefore rendered outside the document window. ... The text that is to the left of the line numbers lies outside the initial containing block.

To accomplish our goals, we are developing a comprehensive instrument description based on Extensible Markup Language (XML) , 1 , a World Wide Web Consortium standard. ... Control Capabilities - what the instrument can do . ... The original name for our language was Instrument Control Markup Language (ICML) . However, since control is no longer our only focus, we decided to rename our language Astronomical Instrument Markup Language (AIML) . ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... Here, we discuss a high spectral resolution data set from the Solar Ultraviolet Measurements of Emitted Radiation (SUMER) instrument on board the Solar and Heliospheric Observatory (SoHO) spacecraft that suggests a linkage between two widely studied features, namely those called 'transition region explosive events (TREEs)' and 'blinkers'. ... Using a blinker identification procedure, we identify blinkers in the light curve of the TREE observed by SUMER in the spectral line OV 629.73 . ...
