![]() In a perfectly thrown pass, the receiver’s running speed will bring him or her to the exact spot where the football arrives at hand-level. So, the quarterback throws the football downfield as the receiver is running in that direction. Likewise, the quarterback throws the football to where the receiver is going to be, not necessarily to where the receiver is currently. ![]() The football follows a curved path into the hands of the receiver. The initial impulse (throw) is all the football gets as far as power is concerned. Think of a quarterback throwing a football to a receiver. The more a spacecraft can “coast” with engines off, the lower the cost of the mission (rocket fuel is not cheap!). As the spacecraft heads toward another planet, the gravitational pull of that planet factors in to the path the spacecraft takes. When a spacecraft is launched from Earth, its forward velocity combined with the gravitational pull of Earth cause it to travel in a curved path. Alternately, have students use more than one piece of cardboard to cushion against protruding pushpin tips. The carpeted floor will absorb the tips of the pushpins that may extend past the thickness of the cardboard. Planetary heliocentric longitudes for appropriate years (search for “planetary heliocentric longitudes” along with the applicable years) ManagementConsider having students sit on a carpeted floor when using the pushpins and string to make an ellipse. String, approximately 30 cm (per student) Graph paper, quadrille ruled (one piece per student)Ĩ.5-by-11-inch or larger piece of thick cardboard (per student) Combine this information with planetary-position data to determine the next launch opportunity to Mars.Use algebraic computations to determine the relative positions of Earth and Mars during which an optimal (low-energy) transfer of a spacecraft can occur.This activity is designed for students familiar with advanced algebra concepts. › Explore more on the Teachable Moments Blog Overview And BEWARE PLANET EARTH! is a great example of what independent video gaming has to offer.This activity is related to a Teachable Moment from Oct. “At BANDAI NAMCO Games, we truly believe that indies are essential for the video games industry because they aren’t afraid of coming up with exciting and fresh games. ![]() “We are really happy to work hand in hand with an independent team as brilliant and as passionate as Lightmare Studio.” said Mathieu Piau, EMEA Marketing Director at BANDAI NAMCO Games Europe. ![]() “We hope you will enjoy playing the game as much as we enjoyed developing it!
