Risk assessments are also utilized in the design of unmanned spacecraft.

NASA uses ground based telecommunications facilities to provide telemetry, command, and navigation services to a number of NASA, other United States, and international spacecraft such as the Space Shuttle other Earth orbiting spacecraft planetary orbiters and international spacecraft.

EB We have to build large amounts of autonomy into the spacecraft so that it can land itself safely.

The new spacecraft are being designed to have an active life 10 times longer than that of the Foton.

The magnetometer design is based on previous experience with devices flown in the missions VEGA and PHOBOS and consists of two sensor, one inside and the other outside the spacecraft.

(b) INTELSAT will discourage manufacturers of its spacecraft from using designs that jettison spacecraft parts, especially near GSO.

Leasing of spacecraft and ground based infrastructure

(g) It would be applicable to mission planning, to the operation of newly designed spacecraft and orbital stages and, if possible, to existing ones

C. The WAVES instrument on NASA apos s WIND spacecraft

Calculations made prior to the launch of United States spacecraft permit the establishment of safe launch windows, ensuring that the spacecraft will not pass near resident manned spacecraft (i.e. Space Shuttle, Mir or the International Space Station).

Work is under way to design a new generation of spacecraft in order to continue research under microgravity conditions.

Research activities continue to focus on the design and development of in situ debris detectors analysis of impact results from detectors and retrieved spacecraft surfaces and characterization of composite spacecraft materials under hypervelocity impact conditions.

In addition, the data from the entire spacecraft as reported through the Orbital Debris Special Investigation Group was analysed and presented in the form of an Engineering Monogram that could be used for design of spacecraft.

Ten different experiments, provided by scientists from Austria, Czech Republic, Hungary, Poland and Slovakia, will be accommodated on the spacecraft, which is being funded by the Italian Space Agency (ASI) and designed by Alenia Spazio.

Aerospace objects in airspace should not be considered as aircraft since special conditions will always apply to their design, manoeuvre and landing procedures.

The power consumed on board a spacecraft was estimated to be in the range of 0.02 150 kW, depending on the type of spacecraft and the mission concerned.

On an immediate basis, the possibility of using the local experience in conceptual engineering for the development of a new generation of spacecraft will be evaluated.

Debris mitigation measures can affect the design and cost of spacecraft and launch vehicles as well as their operations.

Incorporation of debris mitigation measures early in the vehicle design phase could be cost effective.

A classification as aircraft or spacecraft on the basis of the purpose and or destination of the aerospace object may cause confusion.

This spacecraft is scheduled for launch before the turn of the century.

A balance between efficiency and accuracy must be accomplished in order to ensure that computation is a realistic and feasible tool for spacecraft design.

In addition, spacecraft can be designed to place critical components in the geometric shadow of the prevailing direction of debris flux.

In addition, spacecraft can be designed to place critical components in the geometric shadow of the prevailing direction of debris flux.

Aerospace objects should be regarded as aircraft in airspace and as spacecraft in space.

All aerospace objects should be registered as quot spacecraft quot and also as quot aircraft quot .

NASA will provide the other sensors and spacecraft for TRMM.

B. The RAPID Instrument on CLUSTER

. The spacecraft, designed for a five year lifetime, was in a Sun synchronous orbit, dawn to dusk, with a 24 day repeat visit period and a three day subcycle.

ISAS plans to send a spacecraft called LUNAR A to the Moon in 1997.

25. Calculations made prior to the launch of United States spacecraft permit the establishment of safe launch windows, ensuring that the spacecraft will not pass near resident manned spacecraft (i.e. STS, Mir or ISS).

On its second of four planned missions aboard the Shuttle, SPARTAN contained two instruments the NASA designed White Light Coronograph to measure the density and distribution of the electrons in the coronal holes and polar plumes of the Sun and the Ultraviolet Coronal Spectrometer, designed by the SAO.

The spacecraft will carry one radioisotope thermoelectric generator (RTG) to provide on board electrical power and regulate the temperature for spacecraft operation and scientific instruments.

The spacecraft will carry three radioisotope thermoelectric generators (RTGs) to provide on board electrical power and regulate the temperature for spacecraft operation and scientific instruments.

It should be specified that an aerospace object is an object designed for operation in outer space.

11. Given the current orbital debris population, spacecraft designers should consider incorporating implicit and explicit protection concepts into their space vehicles.

Given the current orbital debris population, spacecraft designers should consider incorporating implicit and explicit protection concepts into their space vehicles.

Successful shield designs may take advantage of the structure of the vehicle and the directionality of orbital debris to protect critical components.

Each SMEX spacecraft weighs approximately 250 kg and each mission is expected to cost approximately US 50 million for design, development and 30 days of in orbit operations.

Modifying the designs of spacecraft and launch vehicles to implement mitigation measures generally adds to the system development cost.
