  Price List - Viking Spacecraft to Mars /Joe Frasketi's Philatelic Space Covers
Nasa, in all its wisdom, sometimes designates a spaceflight with a "letter" such as "A" or "B" etc. during the launch phase and after the launch is successful it changes the spaceflight from a "letter" to a "number".

 Spacecraft propulsion - Engineering - A Wikia wiki   (Site not responding. Last check: )
Spacecraft propulsion is used to change the velocity of spacecraft and artificial satellites, or in short, to provide delta-v.
A short period of thrust in the direction of motion accelerates or decelerates the spacecraft into an elliptical orbit around the Sun which is tangential to its previous orbit and also to the orbit of its destination.
The spacecraft falls freely along this elliptical orbit until it reaches its destination, where another short period of thrust accelerates or decelerates it to match the orbit of its destination.

 FAQs
List the different techniques by which petroleum fuels are manufactured.
Ans.: Before designing any spacecraft, it is desired to make a brief sketch of aircraft, it's components and their function, circuits to perform the intended function of spacecraft, it's protection etc. All these points are taken into consideration and various blocks are made to fulfill those consideration called as sub-system of a spacecraft.

 Mars Spacecraft
The spacecraft and attached upper stage either broke up as they were going into Earth orbit or had the upper stage explode in orbit during the burn to put the spacecraft into Mars trajectory.
Shortly before the final phase of the mission, during which the spacecraft was to approach within 50 m of Phobos' surface and release two landers, one a mobile `hopper', the other a stationary platform, contact with Phobos 2 was lost.
The spacecraft was launched into Earth orbit, but failed to achieve insertion into Mars cruise trajectory and re-entered the Earth's atmosphere at about 00:45 to 01:30 UT on 17 November and crashed within a presumed 320 km by 80 km area which includes parts of the Pacific Ocean, Chile, and Bolivia.

 Ulysses Spacecraft
The overall design of the Ulysses spacecraft is dictated by the large distances from the Earth and the Sun at which the spacecraft has to operate (up to 950 million km from Earth, 800 million km from the Sun).
Spin-stabilized (at 5 rpm), the spacecraft's main elements are the box-like main body structure on which is mounted the large-diameter (1.65 m), Earth-pointing High-Gain Antenna (HGA) that provides the communication link, and the Radioisotope Thermoelectric Generator (RTG) that supplies the spacecraft's electrical power.
The spacecraft mass at launch was 367 kg including 55 kg of payload and 33.5 kg of hydrazine for orbit, attitude and spin rate adjustments.

 EO Mission Control: SpaceCraft Overpass Predictor
If you change this value manually, the spacecraft list will be updated to the spacecraft matching your value, or "custom" if your spacecraft is not on our list.
If a value of 30 degrees is selected, for example, and the spacecraft's maximum elevation is 24 degrees for the pass, the pass will not be reported.
An alternate time zone may be selected from this list, or you can indicate that you wish to specify the offset from UTC manually (required if your preferred time zone is not on the list).

 Spacecraft
The spacecraft, built by the Naval Research Lab, was launched on January 25 1994 to a 425 km by 2950 km orbit of the Moon for a 2 month mapping mission.
In early May the spacecraft was to have been sent out of lunar orbit toward a flyby of the asteroid 1620 Geographos but a failure prevented the attempt.
Later in the mission, the Wind spacecraft will be inserted into a special halo orbit in the solar wind upstream from the Earth, at the unique distance which allows Wind to always remain between the Earth and the Sun (about 930,000 to 1,050,000 miles, or 1,500,000 to 1,690,000 kilometers, from the Earth).

 Mars Polar Lander - Spacecraft Description
The lander spacecraft is 3-axis stabilized during the cruise phase and during the entry, descent, and landing event except while descending under the parachute.
Primary communication between the lander spacecraft and earth during cruise are via an X-band link through a fixed medium gain antenna mounted on the cruise stage.
The mass of the lander spacecraft at launch is estimated at 618 kg fully fueled with a dry mass of 562 kg including the micropenetrators.

As of this update in April 2006, the APL Messenger spacecraft is still in the first quarter of its cruise phase.
Frequently, command sequences stored on the spacecraft during cruise or other phases must be augmented by commands sent and executed in or near real time, as new activities become desirable, or, less frequently, as mistakes are discovered in the on-board command sequence.
Changes in data rate and format, and spacecraft maneuvers, are designed to put the flight team and ground systems through their paces during a realistic simulation, in order to provide some practice for readiness, to shake down the systems and procedures, and to try to uncover flaws or areas for improvement.
