Lasers in moon craters could create a lunar GPS system

The moon’s cratered surface. Could these shadows help with making lunar GPS? (Image credit: NASA) Placing ultrastable lasers inside some of the coldest, darkest lunar craters could help scientists establish a GPS-like navigation system on the moon, allowing future Artemis astronauts and spacecraft to navigate the lunar surface more easily. Researchers at the National InstituteContinue Reading

5-hidden-features-of-the-boeing-777-cockpit

The Boeing 777 is the most successful widebody airliner of all time, with nearly 1,800 units having been delivered since the type’s introduction in 1995, and it’s received nearly 2,500 orders across three generations (including the still in-development 777X). Large, efficient, and capable, these planes pioneered the idea of usingContinue Reading
