PTR know how on space missions

PTR know how on space missions Did comets once bring water and life to planet Earth? Ten years ago, Rosetta, the European space probe, was launched in order to find the answer. After "sleeping" for two and a half years, the probe was successfully awakened on January 20 and is due to orbit around comet Churyumov-Gerasimenko starting in August 2014.

The following November, the landing module Philae will set down on the comet‘s surface – something absolutely new in the history of space flight. This is the very first time that a landing has taken place on such a small object. Philae and Rosetta will then accompany the comet on its journey towards the Sun, while carrying out numerous tests and taking many measurements.

However, before all of this can commence, the Philae landing unit needs to be separated from the Rosetta probe.
While this important manoeuvre is taking place, test probes supplied by PTR Messtechnik ensure safe electrical contacts.
As part of close cooperation with the German "Zentrum für Luft- und Raumfahrt" (= Centre for Aeronautics and Space Travel), the decision was taken to use test probes from PTR‘s 1007 series.
Thanks to its maximum compactness design, and to the high quality of materials and workmanship, and above all its ability to compensate for vibration and knocks because of its sprung contacting, it provides everything needed for modern space travel.

This begins with the extreme conditions which occur when an Ariane 5 is launched, and certainly doesn‘t end with the extreme variations in temperature found in space. However, the main aspect is maximum reliability, because in view of the distance of many millions of kilometres, there can be no thoughts of servicing or replacing faulty components.
These are exactly the reasons that the decision was taken to use PTR‘s 1007 series. The test probes combine very good electrical values with low continuity resistance and a high level of contact security with the typically compact design of this series. The 1007 also stands out because of its very high level of workmanship and its optimised surface finish quality, such as goldplated stainless steel springs and the tip style which is designed for a wide range of uses.
