Space, the inner asteroid belt. An LNCHR ship is anchored to an asteroid without atmosphere.
A LNCHR ship is a ship with two main facilities:
- A space crane to raise the slugs filled with minerals from the mining station depots on the asteroid.
- A massive rail gun to launch the slugs to their destination
The slugs themselves are standardized in size and weight meaning that different compartments are going to be filled with minerals of different density.
- radius: 2 meters
- length: 8 meters
- mass when filled: 220 tons approx.
The railgun achieves hurling slugs at 5km/s at the muzzle
For additional details on the asteroid see here. They are quite beside the current question though.
Mr. Y is a man of character. He knows how to get his way. Now that means standing right next to the muzzle of the massive railgun. Which is loaded and ready to launch.
He is in space and wearing an extra vehicular activity suit that allows him good freedom of movement. It is not designed to work outside for long hours.
The railgun is activated and the massive slug passes less than a meter to his side.
What happens to Mr. Y?
I assume there won't be any shockwave
Will he be fried / electrocuted? I have no idea if / how an electromagnetic field will form at the muzzle in space. No idea too if it would be strong enough to damage Mr. Y directly or his suit.
What would be the main hazard for Mr. Y?
The suit is not specifically designed to resist strong electromagnetic fields. It is designed to allow staying outside for a limited period of time (2 hours tops) checking the work of others. Mr. Y does not do. He makes do.
The railgun is powered by generators along its body. They don't leak harmful radiation.
The railgun has already been activated several times before the fatal (?) shot. It's designed to shoot once every 20 minutes. The time is needed to load the slug properly, run checks and prepare it for launch
The railgun is cleared of dust that could come from the asteroid
Before launch operations start the crane is lifted and the anchors removed
The LNCHR is capable of readjusting after each shot to send the slugs along a correct trajectory The LNCHR orbits the asteroid above the equator while loading. Typically depots are built in this area to facilitate the loading process
