In this paper we propose an experiment designed to observe a general-relativistic effect on single photon interference. The experiment consists of a folded Mach-Zehnder interferometer, with the arms distributed between a single Earth orbiter and a ground station. By compensating for other degrees of freedom and the motion of the orbiter, this setup aims to detect the influence of general relativistic time dilation on a spatially superposed single photon. The proposal details a payload to measure the required effect, along with an extensive feasibility analysis given current technological capabilities.
Controller for a pressure and humidity instrument in Martian atmosphere

Finnish Meteorological Institute (FMI) is building a pressure and a humidity instrument for the ExoMars EDM Mars lander of European Space Agency, slated for launch in 2016. The instruments, part of a science package called DREAMS, build on the experience gained on previous meteorological Mars instrument missions participated by FMI. The instruments are based on capacitive Vaisala Barocap and Humicap sensor technologies. Traditionally, the FMI pressure and humidity instruments have been controlled by Field-Programmable Gate Array (FPGA) chips. These components are reliable, but relatively expensive, power-hungry, slow to develop and lack the ability for an in-flight update. This thesis presents a novel approach for controlling these instruments, by developing flight software for performing measurements with the DREAMS-P pressure and DREAMS-H humidity instruments. This design utilizes a commercial automotive microcontroller unit, resulting in a low-power, modi able and scalable system. The successful design and testing of the instrument controller software and functionality is presented.
