MIT Aeronautics and Astronautics (AeroAstro) Student Team Places Second in NASA’s CubeQuest Challenge
JoSS is pleased to announce that MIT’s KitCube satellite design project has placed second in G-2, the second ground tournament of NASA’s CubeQuest Challenge. The CubeSat Challenge offers a total of over $5 million in prizes to teams that can develop CubeSats that can operate in deep space or lunar orbit, and the top three competitors in the final ground tournament will win a spot on the Space Launch System’s Exploration Mission 1 launch, currently scheduled for 2018. Two ground tournaments remain; the next competition, GT-3, takes place in August 2016.
KitCube’s design features novel green monopropellant propulsion technology and a laser communications payload. With these features, KitCube will be competitive for the lunar derby prize (achieved by successfully entering lunar orbit), as well as the best burst data rate prize. The green monopropellant, AF-M315E, was developed by AFRL, and is a less toxic fuel with a relatively high specific impulse. Meanwhile, the laser communications payload is expected to achieve a data rate of >1.5 Mbps over a 30-minute interval from lunar orbit.
KitCube’s student team is composed of a mix of undergraduate and graduate students at MIT, currently with over 45 active team members. Since GT-1, KitCube has also teamed up with Project Selene, a team of high school students from Pasadena, CA. Science and Technology Corp. (STC), the sponsor of JoSS, is one of KitCube’s sponsors.
MIT Aeronautics and Astronautics (AeroAstro) Student Team is Top Contender in NASA’s CubeQuest Challenge
KitCube is a 6U CubeSat that will demonstrate new communications and propulsion technology, led by students and researchers at the Massachusetts Institute of Technology, in collaboration with industry and academic partners. KitCube is competing in the NASA CubeQuest Lunar Derby Challenge for a chance to win a launch opportunity on Exploration Mission-1 (EM-1) on the Space Launch System (SLS). KitCube took 2nd place in the first Ground Tournament (GT-1), and has since partnered with Project Selene, a team of high school students from Pasadena, California, that competed in GT-1.
KitCube is designed to achieve an expected data rate of >1.5 Mbps over a 30-minute interval from lunar orbit. KitCube also serves as a technology demonstration for future miniaturized laser communications payloads, agile, high delta-V propulsion capabilities for CubeSats, and CubeSat missions to lunar orbit. The mission trajectory to achieve lunar orbit is a low energy, bi-elliptic transfer that uses multi-body gravitational effects of the Sun, Earth and Moon to reduce the velocity of KitCube by flying out to 1.7 million kilometers from the Earth, spending several weeks at the external weak stability boundary (WSB), and then falling back toward the Moon to achieve lunar orbit with reduced delta-v requirements. The propulsion system for KitCube uses a green monopropellant, AF-M315E, as a more stable, less-toxic fuel that still has a relatively high specific impulse of 220 s. Thrust will be provided by four 0.5 N thrusters. At the current time, a conservative duty cycle has been assumed for the thrusters of 30 seconds on, 5 minutes off.
KitCube has two separate communications systems, one radio frequency (RF) communications, and one free space optical (lasercom). An X-band radio, paired with the Deep Space Network (DSN), will be the primary operational communications system. KitCube will also have a backup custom, small-form factor UHF radio. The use of an optical communication system drives the need for very fine pointing and control of the spacecraft. KitCube’s attitude determination sensors include two orthogonal star trackers, six sun sensors and an inertial measurement unit (IMU). For attitude control, KitCube will use three reaction wheels, and the four thrusters will be canted towards the center along the y-axis by 2° to enable wheel desaturation and thrust vectoring. The command and data handling hardware will consist of a custom motherboard and three custom interface boards for ADCS, Communications, and Propulsion. All interface boards include Power Distribution Units (PDU’s) to provide power and fault management to the components. Primary power for KitCube will be provided by a deployable two-sided 6U solar panel and body mounted panels on all sides, providing a nominal 40W of power. Secondary power will be provided by three 30 Whr batteries that will provide a nominal power capacity of 90 Whr.
The KitCube team is participating in the second NASA ground tournament, GT-2, in March 2016, and Science and Technology Corporation (STC), the sponsor of JoSS, is one of their sponsors. To see the related crowdfunding website, see https://crowdfund.mit.edu/project/1501.

STC and UMBC Launch NanoSat
Working in collaboration with the University of Maryland, Baltimore County (UMBC), Science and Technology Corporation (STC) sponsored the development of a 5 cm x 5 cm x 12.7 cm nanosat, “Qubscout-S1”, which was successfully launched to a 616 km orbit on November 21, 2013.
STC fabricated the nanosat frame, while UMBC’s Physics Department students and faculty (under Prof. J. Vanderlei Martins) developed the satellite’s sun sensor for attitude control. Qubscout-S1 was launched into sun-synchronous orbit from a Russian Dnepr LV rocket as a part of its Unisat-5 payload, along with a cluster of 28 other small satellites. After a few months of orbit, the satellite will unfold to increase drag and change its rotation rate. Data from the satellite are downlinked to radio receivers at UMBC, where students will analyze the data from the sun sensors to check their performance.
