How millions of people can watch the same video at the same time ' a computer scientist explains the technology behind streaming
Live and on-demand video constituted an estimated 66% of global internet traffic by volume in 2022, and the top 10 days for internet traffic in 2024 coincided with live streaming events such as the Jake Paul vs. Mike Tyson boxing match and coverage of the NFL. Streaming enables seamless, on-demand access to video content, from online gaming to short videos like TikToks, and longer content such as movies, podcasts and NFL games. The defining aspect of streaming is its on-demand nature. Consider the global reach of a Joe Rogan podcast episode or the live coverage of the SpaceX Crew Dragon spacecraft launch ' both examples demonstrate how streaming connects millions of viewers to real-time and on-demand content worldwide. When it comes to video content ' whether it's a live stream or a prerecorded video ' there are two major challenges to address. First, video data is massive in size, making it time-consuming to transmit from the source to devices such as TVs, computers, tablets and smartphones....

Space Tech Startup Apex Lands $200M
The Los Angeles-based startup is helping streamline the approach to satellites with the ability to mass produce spacecraft buses ' the main body and structural component of satellites ' to help meet increasing demand from customers like the U.S. Department of Defense. 'Apex's approach to building spacecraft is key to America realizing its commercial and national security strategies in space,' said founder and CEO Ian Cinnamon. 'This successful raise accelerates our production, allowing Apex to expand its inventory ahead of demand to better enable the missions of our innovative customers, including defense primes, the U.S. government and some of the most exciting companies in the country.' However, so far space tech investment has been slow. Only $1.7 billion was invested in VC-backed startups in Q1, per Crunchbase data. Last year saw a total of $12.5 billion invested in space tech for the whole year....

Bridging Earth and space, and art and science, with global voices
On board Intuitive Machines' Athena spacecraft, which made a moon landing on March 6, were cutting-edge MIT payloads: a depth-mapping camera and a mini-rover called 'AstroAnt.' Also on that craft were the words and voices of people from around the world speaking in dozens of languages. These were etched on a 2-inch silicon wafer computationally designed by Professor Craig Carter of the MIT Department of Materials Science and Engineering and mounted on the mission's Lunar Outpost MAPP Rover. Dubbed the Humanity United with MIT Art and Nanotechnology in Space (HUMANS), the project is a collaboration of art and science, bringing together experts from across MIT ' with technical expertise from the departments of Aeronautics and Astronautics, Mechanical Engineering, and Electrical Engineering and Computer Science; nano-etching and testing from MIT.nano; audio processing from the MIT Media Lab's Opera of the Future and the Music and Theater Arts Section; and lunar mission support from the Media Lab's Space Exploration Initiative....
