space enthusiasts to run space-based Arduino experiments. This is a follow up of ArduSat-1 launched in November 2013. Kaunas University of Technology: LitSat-1 (1) Purpose: To use low-cost open-source hardware and software for its flight computers that will control the satellite payload. The CubeSat carries a VGA camera, a GPS receiver, a linear transponder, and an AX-25 packet radio transponder. Vilnius University: LituanicaSAT-1 (1) Purpose: One of Lithuania's first satellites (together with LitSat-1). This CubeSat is equipped with a low resolution VGA camera, GPS receiver, 9k6 AX25 FSK telemetry beacon, UHF CW beacon, and a 150 mW V/U FM mode voice repeater. The satellite will transmit payload and sensor data images and three Lithuanian words. Southern Stars: SkyCube (1) Purpose: This crowd-funded 1.3-kilogram 1U satellites that features deployable solar panels, four cameras, and communication antennas that are used to receive messages from Earth that are then transmitted at pre-determined times. University of Peru: UAPSat-1 (1) Purpose: This 1U CubeSat uses body-mounted solar panels for power-generation. It is equipped with a minicomputer, radio transmitters/receivers, a power control module, and a basic attitude control system. The satellite will transmit telemetry data and temperature sensor readings from inside and outside the spacecraft. Orbital Sciences CRS Orb-2 Launch vehicle: Orbital Sciences Cygnus (Orb-2) Launch date: 13 July 2014 Total number of CubeSats: 32 Planet Labs: Doves, Flock 1A (28) Purpose: These 28 3U CubeSats are working to build an Earth-observation constellation based solely on CubeSats. The CubeSats contain batteries that provide power to the various systems in each Dove. Each satellite has an optical telescope for acquiring high-resolution images of earth. Each satellites uses an X-band system for the downlink of acquired images and systems telemetry at data rates of 120 Mbit/s. NASA Ames Research Center/San Jose State University: TechEdSat-4 (1) Purpose: This satellites uses commercial off-the-shelf components to provide the basic satellites functions such as commanding, power generation and supply, and communications with the other two units of the satellites. The CubeSat will fly and Exo-Brake to orbit that is deployed once the satellite is released to demonstrate a Passive De-Orbit System for satellites. MIT Lincoln Laboratory: MicroMAS: Microsized Microwave Atmospheric Satellite (1) Purpose: This satellite carries a nine-channel passive microwave radiometer to demonstrate miniaturized radiometer technology in space for application in ultra-compact spacecraft systems such as high performance multi-band sounder for future weather satellites. GEARSSAAT (1) Purpose: This satellite is equipped with
