The ISS travels at 27,500 km/h 🛰 At this speed, the space station orbits the Earth in just 90 minutes. See how unusual this looks in the visualization.

You can do all the cones, bags, and ladder drills in the book, but nothing gets you ready like live reps. Get in open space and use your skillset to score Understand your leverage and your ability to close that space You need to do football drills to get better at football.

First look at Starfield Free Lanes - Cruise mode that allows you to travel in the space between planets now for the first time without having to go through a loading screen. Previously, you would be in front of a planet but not be able to travel much further to explore other planets in space. Now you can free roam space and travel to whatever planet you want to. Its worth noting that you cannot land on a planet seamlessly as you still have to open your map and select where to land.

Jared Isaacman is donating $25M to U.S. Space & Rocket Center's Space Camp 🚀💰 "Space Camp is a national treasure. We need more engineers, scientists, doctors, pilots, astronauts, and explorers in this country to build the future we all wanna live in" "there's a lot we can get out of classroom, but sometimes you need to [get] hands-on with the technology that's going to define the future — like cyber, robotics, aviation, and space, all represented here"
