You are on a space crew, originally scheduled to rendezvous with the mother ship on the lighted surface of the moon. Due to mechanical difficulties, however, your ship is forced to land at a spot some 200 miles from the rendezvous point. During re-entry and landing, much of the equipment aboard is damaged and, since survival depends on reaching the mother ship, only the most critical items available must be chosen for the 200-mile trip. Below are listed the 15 items left intact and undamaged after landing. Your task is to rank them in order of importance (1 being most important) and post your answers in the comments.
Box of matches
Fifty feet of nylon rope
Solar powered portable heating unit
Two .45 caliber pistols
One case of dehydrated milk
Two 100-lb. tanks of oxygen
Stellar map (of the moon's constellations)
Self-inflating life raft
Five gallons of water
First-aid kit containing injection needles
