  1. Is that all? Only ~1 Ton per week?

    Last year, the U.S. Space Force issued alerts for nearly 820 objects entering the Earth’s atmosphere.

    “Re-entries happen each and every day,” "Huge objects weighing a metric ton or more arrive about once a week" according the space collision experts.

    While much of the debris incinerates in the atmosphere or splashes into the Pacific, but when it does not - it can land anywhere and on one can predict where.

    SpaceX indicates ~5% of the mass of some of its satellites may not disintegrate when they "de-orbit". nytimes.com/2026/07/31/world/a

  6. Extended capability electric propulsion coming soon to a Satellite near you soon - thanks to China!

    China successfully demonstrated a new 750-newton Hall-effect thruster (electric propulsion) surpassing the performance of all comparable preceding systems.

    The engine powered Experiment Satellite 26A from its initial transfer orbit to geostationary orbit through five orbit-raising manoeuvres, firing for a cumulative 11,617 seconds (approximately 3.2 hours) during its maiden mission.

    The engine, which was designed to run for nearly 10 hours, operated continuously for more than 14 hours during testing.

    In contrast, the leading US-made R-42DM and Europe’s Leros-1B, are designed to operate for about seven hours. militarywatchmagazine.com/arti #Space #China #Satellite #ElectricPropulsion #ElecticEngine #Hall_Effect_Thrusters #EarthOrbit #SpaceCraft #GeostationaryOrbit

  11. The Sun Climbs Toward Summer Solstice As Earth Continues Its Slow Rotation

    The Northern Hemisphere has 28 days until the summer solstice on June 21, 2026. Days are getting longer, while the Southern Hemisphere experiences winter.

  12. Heads up! Satellite incoming!

    Originally predicted to re-enter Earth’s atmosphere in 2034, the U.S. Space Force (USSF) confirmed that the Van Allen Probe A spacecraft re-entered the atmosphere over the eastern Pacific Ocean region at 6:37 am. EDT on Wed, Mar 11.

    NASA expected most of the spacecraft to burn up as it traveled through the atmosphere, but some components may have survived re-entry.

    Scientists confirmed the sun had reached its solar maximum, triggering intense space weather events which increased atmospheric drag on the spacecraft beyond initial estimates, resulting in the early re-entry. nasa.gov/missions/van-allen-pr #NASA #USSF #VanAllenProbe #Space #SpaceCraft #Re-Entry #Satellite #EarthOrbit #Sun #spaceWeather #Atmosphere

  22. After 53 years in orbit, the Soviet-era Kosmos 482 spacecraft made an uncontrolled reentry into Earth’s atmosphere on May 10, 2025, over the Indian Ocean. Originally intended for a Venus mission in 1972, the craft became long-term space debris due to a launch failure.
