A rocket must carry the fuel it expels in order to accelerate its structure and payload. The rocket equation relates the change in speed to the fuel mass expelled. To launch a spacecraft into Earth orbit requires a multi-stage rocket, since otherwise the mass of fuel required would be prohibitive. While the details vary among historical and…

The Double Asteroid Redirection Test (DART) is a National Aeronautics and Space Administration--European Space Agency collaborative mission to test the feasibility of defending Earth from a catastrophic asteroid impact by using a spacecraft to deflect the asteroid away from the planet.

This article describes the NASA-Funded Space Grant Project BOREALIS: "Balloon Outreach, Research, Exploration, and Landscape Imaging System." BOREALIS conducts high-altitude balloon flights to the "edge of space" with flights typically reaching 100,000 feet and a current record flight in the summer of 2020 that reached 126,000…

Moonshot is the redesign of NASA's High School Aerospace Scholars (HAS), which traditionally engaged Texas high school juniors in a 16-week online course for credit and an intense week-long onsite experience working in teams with experts at NASA's Johnson Space Center (JSC). Due to the novel coronavirus (COVID-19), our challenge was to design,…
