The intended design was to make an electrical contact inside the sensor at 3g, maintaining it through the maximum expected 30g, and then breaking the contact again at 3g to start the parachute release sequence. Instead, no contact was ever made. more>

.. airborne MUOS (Mobile User Objective System) operations were conducted from a system installed in a C-17 Globemaster III aircraft to a communications base station at Joint Base Lewis-McChord Air Force Base near Tacoma, Wash.
Testing included both voice and data operations, with the ARC-210 becoming the first airborne radio to transmit over the full MUOS satellite system.
In addition to supporting Air Force planned testing, the Rockwell Collins team completed interoperability testing with the government’s ground MUOS radio, the AN/PRC-155.
The ARC-210 contains both Demand Assigned Multiple Access (DAMA) and Integrated Waveform (IW) satellite communications capabilities.

Mars has always been a difficult target.
Forty-five missions have been sent: 20 from the US,
19 from Russia and the former Soviet Union,
two from the European Union,
and one each from Japan, China, and India.
Of those, only 19 have been successful. With Mangalyaan, India appears to have broken the so-called “Mars curse.”

The HHPTD weighs approximately five pounds and includes a GPS receiver and internal magnetic and celestial navigation technologies, as well as an internal high-definition color day and thermal night vision sensor and an eye-safe laser rangefinder.
The system is compatible with external precision azimuth and vertical angle modules and provides precision target location information with digital video output, and digital communication for target location data, plus a capability for a near infrared laser pointer.
