Touchdown Activity Simulate landing on other planets.
Delivering robotics to explore Mars and other surfaces!
When NASA engineers try to solve a problem, their initial ideas rarely work out perfectly… they try different ideas, learn from their mistakes… and try again… Design Process Have students write about their design and design process Extension: Document drops with iPhone or appropriate technology
Tony’s Touchdown: Materials list (per team) • 6-7” Paper plate • 3 oz plastic or paper cup • 3 - 4”x 6” Index cards • 3 - Rubber bands • 6 - Straws (flexi-type) • 1 - Boulder-size Marble (or 3-4 regular marbles) • Masking tape • Scissors
4” x 6” index cards
Touchdown: Building your lander • Your ‘astronaut‘ is the marble, not the large marshmallow • Your crew cabin (cup) must be open side up • You cannot change the shape of the cup • Nothing in the cup BUT the ‘astronaut’ • You cannot restrain (hold) the ‘astronaut’ in • the cup by tape • You may cut the paper, the straws, the rubber bands to use in your design
Touchdown: Lander Design Building your lander Principles to Consider • Energy : Potential (position: height you drop from) • : Kinetic (motion: increases as you drop) • Stability : Need to keep the lander upright! • Aerodynamics : Slow down the ‘Rate of Descent’ • Shock absorption: Cushion the landing, absorb the energy, protect the astronaut
NASA eClips: “Challenges of Exploration” Phoenix Mission - 2008
Possible Initial Design?? (Paper cup and plate must be upright) NOW: Design, build and test! > Must keep the marble completely in cylinder on landing!
The . . Drop . . Tests . . . *
Extensions and using TECHNOLOGY • Video the Team drops from 200cm Height • (camera or Smartphone) • Teams TIME 3 drops (stopwatch) • Teams calculate the Average velocity • (cm/second) • Whose slowed the most?? • (Softest landing)
