For launches into Earth orbit the main constraints are the desired orbit, the point of injection into that orbit, and the possibility of a collision with other orbiting spacecraft or orbital debris. For launches to interplanetary trajectories, the time of launch is constrained by the relative positions of the planets, at the time of both launch and encounter(i. e. the spacecraft must be aimed at a point in space that the planet will have reached by the time of encounter). A spacecraft launched outside the launch window would require more propellant and/or more time to reach its target.  2, record 1, English, - launch%20window

Mission : Space surveillance is a critical part of USSPACECOM's mission and involves detecting, tracking, cataloging and identifying man-made objects orbiting Earth, i. e. active/inactive satellites, spent rocket bodies, or fragmentation debris. Space surveillance accomplishes the following : Predict when and where a decaying space object will re-enter the Earth's atmosphere; Prevent a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors of the U. S. and other countries; Chart the present position of space objects and plot their anticipated orbital paths; Detect new man-made objects in space; Produce a running catalog of man-made space objects; Determine which country owns a re-entering space object; Inform NASA whether or not objects may interfere with the space shuttle and Russian Mir space station orbits.  2, record 2, English, - Space%20Surveillance%20Network

Depuis plusieurs décennies, les États-Unis disposent d'un réseau de surveillance spatiale (Space Surveillance Network (SSN), contrôlé par le United States Space Command) qui leur permet de repérer, de suivre, de cataloguer et d'identifier tous les objets de plus de 10 cm qui se trouvent en orbite terrestre, en s'intéressant plus particulièrement aux satellites opérationnels.  2, record 2, French, - Space%20Surveillance%20Network

The project is named the Autonomous Space Processor for Orbital Debris(ASPOD) and is a NASA/Universities Space Research Association(USRA) sponsored design project. The development of ASPOD and the students’ abilities in designing and building a prototype spacecraft are the ultimate goals of this project. This year's focus entailed the development of a secondary robotic arm and end-effector to work in tandem with an existent arm in the removal of orbital debris. The new arm features the introduction of composite materials and a linear drive system, thus producing a light-weight and more accurate prototype. The main characteristic of the end-effector design is that it incorporates all of the motors and gearing internally, thus not subjecting them to the harsh space environment. Furthermore, the arm and the end-effector are automated by a control system with positional feedback. This system is composed of magnetic and optical encoders connected to a 486 PC via two servo-motor controller cards. Programming a series of basic routines and sub-routines has allowed the ASPOD prototype to become more autonomous. The new system is expected to perform specified tasks with a positional accuracy of 0. 5 cm.  2, record 3, English, - autonomous%20space%20processor%20for%20orbital%20debris

CEO [Crew Earth Observations] is conducted primarily from the nadir-viewing, optical-quality window in the U. S. Destiny Laboratory Module. The window can view 39. 5 degrees forward along the axis of the Station, 32. 2 degrees aft, and a total of 79. 1 degrees from port to starboard. The window is constructed of four panes. The outermost pane, made of fused silica, is designed to withstand orbital debris and can be changed out by extravehicular activity(EVA) if it becomes damaged. The two center panes, also made of fused silica, are the primary and redundant pressure panes. The interior pane, made of glass laminate, is called the scratch or "kick" pane. This pane protects the primary pressure pane from scratches and damage caused by contact with the crew, and has an ultraviolet/infrared(UV/IR) coating to protect the crew and improve picture quality.  2, record 4, English, - redundant%20pressure%20pane

The natural space environment refers to the environment as it occurs independent of the presence of a spacecraft; thus, it includes both naturally occurring phenomena such as atomic oxygen(AO) and atmospheric density, ionizing radiation, plasma, etc., and a few man-made factors such as orbital debris.  2, record 7, English, - natural%20space%20environment
