What to bring when the trailhead is in a hard vacuum.
Essentials
- Pressure suit + life support, rated for your destination’s temperature and radiation
- Crampons that bite regolith and water ice
- Relay-sat comms (no cell signal exists)
- Days-to-weeks of consumables — summit pushes run long in low gravity
Leave at home
Down jackets do nothing in a vacuum, and your phone won’t find a bar.
