Last summer, metropolitan areas of Korea including Seoul were hit by an unprecedented heavy rainfall, which inundated various locations. Similarly, torrential downpours engulfed about one-third of Pakistan, leading to widespread flooding. New York State was not spared as it experienced heavy snowstorms in December of last year, with snowfall of more than one meter.

Lockheed Martin cubesats validate essential maneuvers for on-orbit servicing
Lockheed Martin (NYSE: LMT) has announced that its In-space Upgrade Satellite System (LM LINUSS) accomplished a successful on-orbit demonstration, proving how small satellites can serve an essential role in sustaining critical space architectures. They do this by regularly upgrading existing constellations with new capabilities and extending spacecraft design lifecycles.
LM LINUSS, a techn Lockheed Martin's first LM 400 multi-mission space vehicle completes testing milestone
The first Lockheed Martin (NYSE: LMT) LM 400, a versatile, mid-sized satellite which can be adapted for military, civil or commercial uses, has successfully completed Electromagnetic Interference/Electromagnetic Compatibility testing. This trial is crucial to ensure that signals from the satellite bus components will not interfere with critical payloads during operations.

Cargo spacecraft is robotic spacecraft designed to support space station operation by transporting food, propellant and other supplies. Tianzhou cargo spacecraft (The abbreviation is TZ) is a Chinese automated cargo spacecraft developed by the China Academy of Space Technology, as part of China's manned space Station program. The China Academy of Space Technology began to design TZ in 2010. 'Complacency' must be avoided to maintain U.S. superiority in space, Saltzman says
Chief of Space Operations, Gen. Chance Saltzman April 19 praised the United States' proud and trailblazing history in space but said the rapidly changing and more dangerous domain requires new actions, thinking and focus.
"This crowd is passionate about space; I see no signs of apathy," Saltzman said during his keynote speech at the 2023 Space Symposium, a large gathering of government, mi Kendall explains why success in space requires 'transformational change'
Emphasizing that space capabilities are "important to our strategy of integrated deterrence" and the reason U.S. Space Force must drive "transformational" change, Department of the Air Force Secretary Frank Kendall offered a blunt assessment April 19 of the challenges today in space but also optimism that the United States would maintain its dominance in that domain.
