In September 1996, the impact ionization detector Geostationary Orbit Impact Detector (GORID) was placed into GEO on board the Russian telecommunication satellite Express 12.

The international satellite project INTERBALL comprises two large satellites, one in a fairly low orbit (Tail Probe), whereas the other is in a highly eccentric one (Aurora Probe) see also activities of the Space Research Institute Graz.

However, ESA will place a debris and dust detector in the geostationary orbit.

The LEED experiment was conducted by KITSAT II at the orbit altitude of 800 km.

Detection of neutral particles in orbital altitudes and Technological demonstration.

B. Radar detection and measurement of orbital debris (FGAN)

In 1996, an ESA debris and dust detector was placed in geostationary orbit on the Russian spacecraft Express 2.

This experiment consists of a cosmic particle detector and a total dose measurement detector, which together have 512 measurement channels.

The Galileo spacecraft successfully entered into orbit around Jupiter and sent its instrumented probe into the atmosphere of Jupiter.

As has already been announced, the Mars 96 space probe launched on 16 November 1996 did not succeed in reaching the flight trajectory to Mars and remained in a terrestrial orbit.

It was aimed to probe the Earth apos s plasma environment with four identical spacecraft on almost identical orbits.

Survey personnel also helped plan for Surveyor orbiter and lander missions projected to take place between 1998 and 2005.

If an identified object is predicted to pass within the warning box near the orbiter (25 kilometres along the orbit and 5 kilometres both radial and out of orbital plane), the Space Surveillance Network is requested to make additional observations and use them to compute a more accurate orbit of that object.

It has a little tiny bit of gravity, but it's enough that it can pull the asteroid, and you have your rockets set up, so you can oh, you can barely see it here, but there's rocket plumes and you basically, these guys are connected by their own gravity, and if you move the probe very slowly, very, very gently, you can very easily finesse that rock into a safe orbit.

Debris detectors.

CNES plans to use the same detectors on the French satellite STENTOR in geostationary orbit (1999) and in heliosynchronous orbit on an Israeli satellite (1999).

High sensitivity of light detectors used in the instrument was obtained through the use of small cooling coils allowing measurement of the neutral temperature of the spacecraft in the dark parts of the orbit, i.e. the temperature of high strata of the atmosphere at night.

The gravity of the asteroid pulls on the probe, and the probe has a couple of tons of mass.

The United States Space Command employs 1 metre aperture telescopes fitted with intensified vidicon detectors to track HEO objects.

The Subcommittee noted missions planned for future launch, including Mars 96, Planet B, Mars Surveyor, Orbiter and Pathfinder, for investigation of Mars Lunar Prospector for lunar exploration Cassini Huygens, for investigation of Saturn and its moons and the Near Earth Asteroid Rendezvous (NEAR), Stardust and Rosetta missions to asteroids and comets.

Tests have been conducted on combined ground penetrating radar metal detectors and on infrared detectors.

Some 82 investigations sent into orbit by 75 principal investigators from 13 countries showed how crewed space laboratories can be used with high efficiency in international investigations such as those to be done on the Space Station.

The Unit has a long heritage in developing and flying in orbit sensors to detect the microparticle population.

These studies have demonstrated that there are significant selection effects where objects in eccentric orbits are less likely to be detected than those in circular orbits.

All passengers have to go through a Walk through Metal Detector, Hand held Metal Detector and X ray machine before boarding.

Earlier flights did not carry so many redundant probes on one payload, so that one could not become aware of possible deficiencies of certain types of instruments.

We sent a probe out to this asteroid belt, called NEAR, Near Earth Asteroid Rendezvous.

This is our current detector.

One of the main objectives is detection and tracking of mid size space debris (size 1 50 cm) in LEO.

Space Shuttle Orbiter

A Tracking, Telemetry and Control (TT amp C) station is used to support polar satellites during the launch phase and when in service in their nominal orbits.

DEBIE (Debris In Orbit Evaluator) is one such sensor.

It will have an ionospheric measurement sensor, ozone measurement sensor and X ray detector as payload.

And the thing I came up with I have to first give you an introduction about the idea, and maybe that would be a meaning detector, rather than a life detector.

NASDA will add the orbital data of its own spacecraft acquired through observations conducted by the National Astronomy Observatory.

SPS consists of a high energy particle detector (HEPD) and ionosphere measurement sensor (IMS).

The ULYSSES probe, an example of cooperation between Europe and the United States, flew by the south pole of the Sun.

They're essentially digital cameras.

1.2.1 Retrieved surfaces and impact detectors

Typically, radar measurements have been used for space debris in low Earth orbit (LEO), while optical measurements have been used for high Earth orbit (HEO).
