... You will need to allow time for an acquisition in virtually all cases. An ONBOARD ACQ with the GHRS should be used unless it will clearly not work. ... If the STEP-TIME you need to get 100 or more counts in the peak pixel exceeds about 2 seconds then you have a faint-target acquisition, and you should use the longer time on the Phase I work sheets. ... Thus it is generally to your advantage to construct visits so that they only use one Side or the other, or at least so switching is minimized. ...

Triad, launched September 2, 1972, was an experimental spacecraft designed to move in an accurately predictable low-altitude orbit, allowing its position to be used as a reference point in navigation. ... While the "proof mass" thus moved in an accurately predictable orbit, the spacecraft itself was subject to air resistance and sunlight pressure, causing it to move slightly differently. ...

... The only event-driven pieces of software were the user interface Hermes, the display server GIDS and the GDS server. ... Event-driven tasks are fundamentally different from procedural tasks. ... Using this event handling, a collection of routines has been built, which allows the programmer to construct a graphical user interface for a task. ... These are the events associated with user input keywords and one other event which is generated when a task is resumed after it was pausing. ...

This image of Pluto from NASA s New Horizons spacecraft, processed in two different ways, shows how Pluto s bright, high-altitude atmospheric haze produces a twilight that softly illuminates the surface before sunrise and after sunset, allowing the sensitive cameras on New Horizons to see details in nighttime regions that would otherwise be invisible. ... The image was taken as New Horizons flew past Pluto on July 14, 2015, from a distance of 50,000 miles (80,000 kilometers). NASA/JHUAPL/SwRI ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
