Challenge Categories

Home Is Where the Pod Is

Objective Statement

Send crickets to 100,000+ feet and return them safely to earth

Mission profile

Keeping living specimens alive during space travel is an important technology for the long-term space exploration and/or habitation of other celestial bodies. In this mission, teams must develop environmental controls to ensure live specimens, crickets, survive the space environment for a flight lasting approximately 4 hours at an altitude up to 112,000 feet. Considerations include thermal control, atmospheric pressure, oxygen levels and short-term radiation exposure mitigation.

Mission Success Criteria

In this mission, teams are tasked with creating a cricket survival pod capable of withstanding the harshness of a high-altitude ballooning mission at an altitude of 100,000+ feet for a period of 4 hours. The survival pod should be large enough to contain 3 crickets, fit within the 1U CubeSat form factor, and meet the weight requirements. The successful missions will create a vacuum seal and maintain cricket health for over 4 hours during the ballooning mission. A minimum of 2 of the 3 crickets must be safely returned to Earth as evidenced at the CubeSat recovery stage of the mission. The CubeSat recovery team will take photos of crickets upon recovery to verify survival rates.

Objective Statement

Develop a CubeSat imaging system capable of taking 1 picture every minute during flight.

Mission profile

Imaging technology is routinely deployed in space missions to track cloud cover and weather patterns, aid celestial navigation, observe Earth land changes and much more. The use of a camera, however, brings many challenges including optics, positioning and pointing, hardware mounting, and data storage. This mission challenges teams to develop a camera system capable of taking pictures of the near-space environment during a high-altitude ballon flight and store the data to a local hardware memory.

Mission Success Criteria

Teams will develop and operate a camera imaging system capable of capturing images during high-altitude balloon flight. The camera system must capture at least 1 image per minute over a 4-hour flight with images exposing the near-space environment. Images must be stored to an onboard microSD data storage as time-stamped files documenting the duration between images. The CubeSat recovery team will remove the microSD card and acquire the stored images to assess challenge success.

Objective Statement

Develop a release mechanism to disperse native maple seeds during flight.

Mission profile

Robotic mechanisms are a critical technology used in space missions. Robotics enable inspection, manipulation of hardware components and triggering of events within spacecraft to ensure mission success. In this mission, teams will be tasked with developing a robotic mechanism that will release native maple seeds during flight. A successful mechanism will store the seeds during the launch phase of the mission and then safely disperse the seeds during flight. 

Mission Success Criteria

The CubeSat will have the capacity to store 10 native maple seeds in a protective compartment for the launch phase of the mission. A mechanism must be constructed which will release the seeds during flight. The CubeSat recovery team will take photos of the CubeSat upon recovery and verify the remaining number of seeds.  The successful teams will have fewer than 2 seeds in their CubeSats at the time of recovery.

Objective Statement

Develop a remote sensing system to monitor the near-space environment during a high-altitude balloon flight.

Mission profile

Most scientific satellite missions employ some form of remote sensing payload to monitor environmental conditions. Whether it is to measure the radiation intensity around Jupiter, or the electromagnetic field of the Earth, satellites use remote sensing systems to acquire information about their surroundings or to make scientific discoveries. In this CubeSat mission, teams are challenged to develop a remote sensing system capable of acquiring data from a minimum of three sensors as a function of time during a high-altitude balloon flight. Sensors may be digital or analog or a combination of both and may include environmental sensors (e.g. temperature, pressure, gas composition, etc.) or position sensors (e.g. GPS, accelerometers, etc.).

Mission Success Criteria

The remote sensing package must be enclosed in the 1U CubeSat and acquire data at a rate of at least 1 sample per minute for over 1 hour of flight. The data must be stored to a microSD device as a single data file. The data file should be organized as a table with either comma or table delineation separating the columns and carriage returns separating the rows. Each row in the data table should contain a timestamp or elapsed time counter.  The data table should also contain a header specifying the name and units associated with each column. The successful mission will validate the collection of flight data at the conclusion of the mission. The CubeSat recovery team will access the microSD memory card and download the data file.

Objective Statement

Identify and utilize radiation shielding to reduce radiation exposure by 50%

Mission profile

Radiation exposure while in space is considered one of the most hazardous environment factors limiting human habitation. Radiation exposure to living organisms can damage cellular tissues causing premature cell death or disrupt DNA causing mutations and increased cancer risks.  In this mission, teams are challenged to identify and utilize radiation shielding materials to reduce radiation exposure by at least 50%. The CubeSats will fly two identical Geiger counters, one will be exposed to the space environment, and the other will be shielded using the selected materials and shielding methods. The team must develop a data collection system to monitor the two Geiger counters and then calculate the overall radiation exposure difference from the two sensors.

 Mission Success Criteria

The successful team will develop a CubeSat containing two Geiger counters, one unshielded and one shielded. The shielded counter will employ whichever methods and materials selected by the team. You will continuously record radiation exposure data (counts per minute) from the two Geiger counters and create a log file reporting counts per minute, every minute during flight, for a minimum duration of 1 hr. The data file(s) must be time stamped to ensure data is gathered while in flight and synchronously between the two counters. The data will be recorded to a microSD memory card. The CubeSat recovery team will remove the microSD card upon recovery and analyze the data. To be successful in this challenge, total counts in the shielded Geiger counter must be 50% less than the unshielded Geiger counter over the full operational duration.
