A fleet of refuelable Supernova vehicles at medium-Earth and geostationary orbit capable of swooping down to various orbits and providing services such as propellant ⛽ delivery, mobility, and observation for commercial and military #satellites 🛰️.

The war in #Ukraine 🇺🇦 has left a deep impression on Europeans, and they have seen the value of secure #satellite 🛰️ Internet. The difficulty is in how to get there. The continent does not have a reusable rocket like #SpaceX's Falcon 9, nor the capacity to rapidly build hundreds of complex satellites. There is the challenge of coordinating such a complex endeavor across many different constituencies https://arstechnica.com/space/2024/05/europes-ambitious-satellite-internet-project-appears-to-be-running-into-trouble/

The #ISS isolated strains were mutated and became genetically and functionally distinct compared to their #Earth counterparts. The strains were able to viably persist in the ISS over time with a significant abundance. E. bugandensis coexisted with multiple other #microorganisms 🦠, and in some cases could have helped those organisms survive. https://www.nasa.gov/centers-and-facilities/ames/ames-science/ames-space-biosciences/multi-drug-resistant-bacteria-found-on-iss-mutating-to-become-functionally-distinct/

#Starlink hosts more than 10,000 laser communications systems on orbit. Those lasers can sustain 100 Gbps connection 📶 per link. #VastSpace and #SpaceX announced in May 2023 a plan to launch #Haven1 as soon as 📆 August 2025. The commercial station would feature the ability to spin and generate enough centripetal force to create the equivalent of #gravity on the Moon. https://aviationweek.com/shows-events/space-symposium/vast-space-station-use-spacex-starlink-laser-comms

@Eka_FOOF_A her rpoint is "Unlike meteorites ☄️, which are small and only contain trace amounts of aluminum, these wrecked spacecraft are huge and consist entirely of aluminum and other exotic, highly conductive materials. And highly conductive materials can create charging effects and act as a magnetic 🧲 shield" (NOT the "space dust that is very similar to plain earth dust")

#Moon 🌙 scouts will all be #robotic, designed to build a foundation for #astronauts 👨‍🚀 to follow about two years later. There is need for transporting 🚀 large masses of equipment and materials from #Earth.

Objectives of ten or 20 years from now, like building #lunar settlements, exploring mineral deposits on the #Moon and efficiently repairing #SpaceStation modules can only be achieved using #robotics. Due to possible disruptions in normal operations, like a small #meteor shower damaging the #robot, or hacking carried by a hostile group or state, humans 👩‍🚀 must be ready to step in.
Modern #spacesuits will be a key foundation of this collaborative relationship. https://www.astronomy.com/space-exploration/the-upgrades-to-spacesuits-that-need-to-be-made-sooner-rather-than-later/

The potential global economic impact of #SpaceWeather events is significant and could incur losses totalling 38.4 billion € 💰 per day. The lack 🔮 of information about space weather can also cause significant damage to satellites and other space systems.

Launch costs have fallen 95% 📉 (with another massive reduction expected in the coming years) thanks to reuse, improved engineering, and increased volumes.
