... 2002 September 29 . Venus: Just Passing By . Credit: Galileo Project , JPL , NASA . Explanation: Venus, the second closest planet to the Sun , is a popular way-point for spacecraft headed for the gas giant planets in the outer reaches of the solar system. Why visit Venus first? Using a " gravity assist " maneuver, spacecraft can swing by planets and gain energy during their brief encounter saving fuel for use at the end of their long interplanetary voyage. ...

... Fit the ring around the equator and then change its inclination from 0 degrees (equatorial orbit used by geosynchronous satellites) to 28.5 degrees (space shuttle orbit) to 51.6 degrees (space station orbit) to 90 degrees (polar orbit used by spy satellites). by Rob Landis, Space Telescope Science Institute . ...

The Optical Solar Sensor (OSD) has been designed to determine the direction towards the center of the Sun's visible disc. The direction to the Sun is computed in the instrument coordinate system relative to the pixels' position on the linear CCDs illuminated with the light passed through the incoming coding mask. The OSD coding mask has three groups of slits with three slits in each group. This mask configuration provides for reliability increase as well as for the required accuracy. ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

... The pinhole simulation program is a computationally and memory intensive task. ... A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. ...

... This task takes an OM OSW source list, with source positions in pixels, and converts to sky coordinates. These sky coordinates are then used to produce a sky coordinate image. The task requires the user to enter the name of an OSW source list and its corresponding OSW image. ... The tangent plane coordinates are then converted to sky coordinates. ... The algorithm sets up a grid of offsets in the x and y directions to be used to match up stars in the source list to those in the catalogue. ...
