Reaching means accelerating up to around 28,000kph (22 times the speed of sound). A five-gram 🔩 hitting at packs as much 💥 as a 200kg weight dropped from the top of an 18-storey building. The typical ☢️ dose from one day in is equivalent to what you’d receive over an entire year back on https://www.sciencefocus.com/space/space-travel-exploration

revesdespace,

@spaceflight So do you think ther is a design problem on starship for space debris concern ? Or not as it is planned to be used above Earth low orbit ?

spaceflight,

@revesdespace at least if there are people or tons of propellant on board (in ) they should consider additional shielding
