How NASA Prepares Astronauts In Zero Gravity | Trajectory | Spark

Since the early days of space exploration, scientists have already found a way to test technologies in zero gravity, lunar gravity, or even martian gravity on Earth. Technics pioneered for the early space program are still finding widespread uses in modern research. After the Apollo 1 fire incidents, unmanned spacecraft testing became the new normal and NASA was preparing to launch the Apollo 5. With the clock ticking, rebuilding Project Apollo became a tougher task. -- Revisit the key advances that have marked space exploration and find out the very latest innovations in space science. --- Subscribe to Spark for more amazing science, tech & engineering videos: https://goo.gl/LIrlur 🚀 Join the Spark Channel Membership to get access to perks: https://www.youtube.com/channel/UCMV3aTOwUtG5vwfH9_rzb2w/join Find us on: Facebook: https://www.facebook.com/SparkDocs/ Instagram: https://www.instagram.com/spark_channel/ Any queries, please contact us at: owned-enquiries@littledotstudios.com #Spark #NASA #apollo
