This summer, launch into the realm of space exploration with NPR’s science podcast series, Space Camp, delving into the fascinating mysteries of the universe. The journey begins with an exploration of the fundamental science behind reaching outer space.
To traverse the expanse of space, one must embark on a spacecraft tethered to a powerful rocket. As the rocket propels upward, exhaust gases are expelled downwards according to Newton’s third law of motion, creating an opposing force that thrusts the rocket skyward.
Experiencing intense g-forces during liftoff, astronauts are pushed into their seats until reaching weightlessness upon detachment from the rocket. Despite floating in microgravity, the pull of Earth’s gravity persists, resulting in a sensation akin to freefall.
Gazing out from the International Space Station, astronauts witness the curvature of Earth as they orbit above. Newton’s thought experiments illustrate how achieving orbit involves continuous falling around the planet without ever making contact with its surface.
Next week on Short Wave Space Camp, explore the enigmatic dwarf planet Pluto and the intriguing dynamics of our solar system. Learn why Pluto was reclassified as a dwarf planet and uncover the unexpected revelations about its geology.
