  • Our task is to design and build a prototype experiment that could be performed on Mars during the Mars Sample Return Mission.

  • The experiment must fit into an 18 inch cubeThe experiment must weigh less than 10 kilogramsThe experiment is allocated 50 watts of energy from the LanderThe experiment must be completed during the duration of the mission

  • Record and collect atmospheric data at various levels of the Martian atmosphereMeasure Atmospheric temperature, pressure, wind speed, radiation, magnetic force, and humiditySecondary objective is to take a photo of the Mars Sample Return Lander from above

  • Martian Balloon

  • The Martian Balloon idea consists of balloon that floats up into the Martian atmosphere and carries a payload of various scientific instruments that measures atmospheric data. Due to the low atmospheric density of mars, a very large balloon is required to displace enough air to create a buoyant force large enough to allow the balloon to rise. The Density of the Martian atmosphere based upon previous experiments was found to be around .02 kg/m3According to Archimedes's principle, our balloon, the payload, and the helium inside of the balloon would have to weigh less than the Martian atmosphere in order to float.

  • Energy StorageBalloon DeploymentData Measurement, Storage, and Transmission

  • Balloon Thickness- 5x10-5 mBalloon deflated Volume- .0323 m3Balloon Material- Mylar, Kevlar, Polyethylene, and AdhesiveBalloon inflated Volume- 381.7Inflated Balloon Mass- 6.3 Kg

  • Payload Mass- 1KgPlatform dimensions- 14x14x.0625Platform Material- TitaniumAll scientific instruments are mounted on the platform

  • Two computers: the Lander System (LASY) and the Balloon System (BOSS)Unsure of how much well be able to use the Landers computer, so LASY was included. Controls lifting mechanism and possibly communications with BOSS.BOSS must be as lightweight as possible. The weight of the entire computer system (motherboard, processor, flash memory) must be under .4kg.Expecting technology to evolve exponentially before the mission launches

  • Two types of trade studySpring load the balloon from the Lander to the ground and deploy from there.Shoot the helium into the balloon and inflate it from the top of the Lander in a cone shape. This would create an upside down tear drop shape.Lifting Mechanism OptionInflate an air bag to raise the packaged balloon out of the 18 inch cube.

  • Mylar- A plastic film that can take shape and form the skin of the balloon.Polyethylene- A common balloon material that retains helium well.Kevlar Scrim- Added to the polyethylene to make the skin of the balloon more resistant to tearing.Adhesive- strong durable glue to hold previous materials together.

  • The thicker the balloon the more volume it occupies, and the heavier the balloon, but it makes a more durable balloon.The thinner the balloon the less volume it occupies, and the lighter the balloon, but it will be less durable.

  • Solar Power: May provide a longer measurement sample during flight due to regenerative power. But, would cause extra hardware and weight. Also, there is limited solar exposure.Battery Power: Lithium Ion batteries add to the payload weight, but can be charged by Landers power supply.
