Gravity: decompression sickness, orbital mechanics, and jet chairs

Criticism

Sloppy orbital mechanics and the value of science-adjacent entertainment.

Ed Harris

Forever the voice of Mission Control.

Space is dangerous

Almost as scary as the ocean.

EVA jet chairs

NASA’s MMU. The new tiny one: SAFER! Giant rectal rectangle jet chairs?

Where and how things orbit

Earth-orbital distances. Where different kinds of man-made satellites operation and how they are not likely to run into each other roughly ever. The utility of geostationary orbits.

earth orbits

Wikipedia has the awesome animated version here

Orbital impacts

Relative velocities. Could you dodge a sniper bullet? IRL ISS escape procedures. Soyuz escape plans.

Deadspin

Glowing blood and possible alien infections. Human sensitivity to positive and negative g-forces. Trying to push more blood to your head for mental superpowers.

Orbital transfer

And impromptu deorbiting. How to crash a probe into mars (by accident).

Pressurization

Chinese space stations, then and now. Station entrance and exit procedures. Finally the Star Trek balloon analogy comes in handy! Decompression sickness/the bends during EVA. Portable life support systems. Sokol and ACES, and their insufficiency for extra-vehicular activities.

Fire extinguishers

…in spaaaaaace. Carbon dioxide. Water. Super soakers. Fire emergency procedures.

EVA Suits

Past designs and modern designs. Future EVA suit developments. Constrictive suits directly against the skin rather than creating an atmosphere around the body: the biosuit. The NASA Z Suit that looks like Buzz Lightyear, and operating EVA suits at the same pressure as your space station.

Reentry

Soyuz reentry angles. Heat shielding. Trying to point in a particular direction.

Lifting

The complete obviousness that heavy compound weight lifting is the major solution to muscle and bone loss in space. Bro do you even lift? Vacuum-based space squat rack.
