Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby buildings. Katerina Kaouri details how scientists use math to predict sonic booms' paths in the atmosphere, where they will land, and how loud they will be. Lesson by Katerina Kaouri, animation by Anton Bogaty.

We are on a mission: to pave the way for supersonic air travel over land and cut our flight time in half. With the innovative X-59 aircraft, we're working to prove that a sonic boom can be reduced to a quieter, acceptable sonic thump. This is NASA's Quesst.

Twin solid rocket boosters that will produce a combined 7.2 million pounds of thrust at liftoff, a towering core stage, and the only human-rated spacecraft in the world capable of deep space travel – together, NASA’s Space Launch System rocket and Orion spacecraft stand ready to usher in a new chapter of exploration. Now fully assembled at Kennedy Space Center in Florida, SLS and Orion will soon launch on the uncrewed Artemis I mission around the Moon, paving the way for astronauts. Artemis I represents a new generation of spaceflight capabilities and partnerships that will take humans back to the Moon and beyond.

What does it *really* feel like to jump from space? In 2012 Felix Baumgartner took a helium balloon into the stratosphere and skydived back to earth in a specially made space suit. Whilst in freefall he broke the speed of sound and entered a spin which threatened the entire Red Bull Stratos mission... Felix reflects on his achievement and shares what it really felt like to jump from the edge of space. check out the full story behind Red Bull Stratos in 'Space Jump' on Red Bull TV https://www.redbullstratos.com #RedBull #GivesYouWiiings #RedBullStratos _________________________________________________ Experience the world of Red Bull like you have never seen it before with the best action sports clips on the web, original series and livestreams.

Using the lunar surface as a proving ground for living on Mars, this next chapter in exploration will forever establish our presence in the stars. ✨ We are returning to the Moon – to stay – and this is how we are going! Actress Kelly Marie Tran of “Star Wars: The Rise of Skywalker” lent her voice to this project.
