SpaceX made strides in both Starship and Starlink missions this week, launching another round of satellites while concurrently testing their Starship capabilities amidst challenges.
On April 22, 2010, an Atlas V lifted off from Cape Canaveral carrying a reusable robotic spaceplane so secret that the Air Force would not even confirm its mission duration. It came back 224 days later, lighter, quieter, and more operational than anyone outside Washington had expected. Fifteen years later, the X-37B is still flying, and the military still will not say what it does.
SpaceX continues to push forward with its ambitious plans as the FAA investigates Starship debris reports, while Starlink maintains robust satellite operations.
Today's brief covers advancements in satellite technology initiatives by the U.S. Space Force, geopolitical implications in maritime domains, and Sweden's significant military aid package. Additionally, we spotlight a historical satellite with modern implications.
