Beagle2 Mars Lander, Umbilical Connector

Scientific paper

This paper details the design and development process for the umbilical connector for the Beagle2 Mars Lander. The umbilical connector provides electrical power and vital telemetry from Mars Express to Beagle2. A mated pair of MIL-DTL-38999 Series IV connectors using standard 15-35 arrangement was extensively modified to meet the technical challenges of the mission, while accommodating the mechanical interface of the two spacecraft. In the latter portion of this study, theoretical calculation of ejection mechanism was utilized to predict the umbilical connector separation force and time. The predicted values were then compared with the experimental data obtained and found to correlate very well. In addition, the empirical tests also demonstrated excellent reliability of the connector after short and long-term exposure to thermal vacuum condition. Overall, the test results proved that the design of this umbilical connector was very robust and met all technical requirements.
