High School Seniors Sanzio Angeli, of Clover Hill High School, and Dylan Whitesel, of Midlothian High School, hope to raise money and awareness for Breast Cancer research and break a world record at the same time. They are combining their love for model rocketry with community citizenship to create "Rocket4theCure." Sanzio and Dylan are selling model rockets for $10 each to be launched simultaneously, hoping to launch 4,000 rockets, which would shatter the standing record, all while raising money for The Central Virginia Affiliate of Susan G. Komen.

Descent Rate Calculator

This tool estimates the descent rate for your rocket rocket as it falls to the ground under its parachute. This calculator is based on the original EMRR calculator by Jordan Hiller.

Enter the weight of your rocket (don't forget to include the weight of the expended motor). Then enter the diameter (or maximum width) and choose the approximate shape of the parachute. Optionally, enter the altitude at which you expect the parachute to deploy.
