It took 225 years โณ to find the 1.5 million #asteroids โ˜„๏ธ known to date. The Vera C.

Simulation: New telescope soon to detect millions of objects in the solar system

In a few days, the first images from the Vera C. Rubin Observatory are to be presented. Simulations are now raising expectations of the instrument.

More than half of the โ€œcity killerโ€ ๐ŸŒƒ #asteroids โ˜„๏ธ that might threaten Earth remain undiscovered. The blast from an #asteroid of 140 meter ๐Ÿ“ would be roughly 600 times ๐Ÿ“ˆ more destructive ๐Ÿ’ฅ than #Chelyabinsk, because a doubling in diameter increases a space rockโ€™s kinetic energy by eight times. Observing ๐Ÿ”ญ in the infrared, #NEOSurveyor* will see those hidden asteroids glow like fireflies in the night https://www.science.org/content/article/nasa-telescope-will-hunt-down-city-killer-asteroids

#Europe ๐Ÿ‡ช๐Ÿ‡บ 2025 : mostly statements of intent, words like โ€œplan,โ€ โ€œcapacity,โ€ โ€œinvestment,โ€ and โ€œbuildโ€. The growth in public and private funds ๐Ÿ’ฐ was due to the widespread recognition that #space is vital to the modern age.

Civilian and #military operators alike need spacecraft that can withstand the brutal conditions of #space ๐ŸŒŒ. That means resistance to #radiation โ˜ข๏ธ, to heat, to #electromagnetic pulses and to targeted disruption. Forms of technology that make #satellites more resilient will also cut costs and improve #civilian services. #Berlin plans to spend 35 billion euros ๐Ÿ’ฐ on military space capabilities between now and 2030. The challenge is speed โฑ๏ธ and #regulation https://spacenews.com/what-germany-got-right-and-wrong-in-its-first-ever-space-strategy/
