INSTRUCTIONS: You are a member of a space crew originally scheduled to rendezvous with a mother ship on the lighted surface of the moon. Due to mechanical difficulties, however, your ship was forced to land at a spot some 200 miles from the rendezvous point. During landing, much of the equipment aboard was damaged and since survival depends on reaching the mother ship, 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 order them in terms of their importance for your crew in allowing them to reach the rendezvous point.

Place the number 1 by the most important item, the number 2 by the second most important, and so on through number 15, the least important.

_ Box of matches
_ Food concentrate
_ 50 feet of nylon rope
_ Parachute silk
_ Portable heating unit
_ Two .45 caliber pistols
_ One case dehydrated milk
_ Two 100 lb. Tanks of oxygen
_ Stellar map of the moon?s constellation
_ Life raft
_ Magnetic compass
_ 5 gallons of water
_ Signal flares
_ First aid kit containing injection needles
_ Solar-powered FM receiver/transmitter


My Answers.

1 Two 100 lb. Tanks of oxygen - Need o2 😉

2 Food concentrate

3 5 gallons of water - Gotta hydrate.

4 First aid kit containing injection needles

5 Solar-powered FM receiver/transmitter - critical for communication.

6 Portable heating unit- assuming you already have space suits that keep you warm ;p

7 Magnetic compass - Not sure if the compass would be to useful... magnetic fields are different on the moon...

8 Life raft - No water on the moon, however, could possibly be used as shelter..

9 50 feet of nylon rope

10 Signal flares - I assumed the radio would replace the signal flares in cases of emergency... especially if the flares dont work in space

11 One case dehydrated milk - Who needs milk? Its probably whole milk and not skim... so i wouldnt drink it anyway 🙂

12 Parachute silk

13 Stellar map of the moon?s constellation - Who cares about the moon's constellations

14 Two .45 caliber pistols - No oxygen to spark the gunpowder even if u needed to use the gun...

15 Box of matches - No oxygen to make fire
 
12 Box of matches
4 Food concentrate
7 50 feet of nylon rope
11 Parachute silk
3 Portable heating unit
13 Two .45 caliber pistols
10 One case dehydrated milk
1 Two 100 lb. Tanks of oxygen
6 Stellar map of the moon?s constellation
5 Life raft
14 Magnetic compass
2 5 gallons of water
15 Signal flares
9 First aid kit containing injection needles
8 Solar-powered FM receiver/transmitter

I doubt I would even take 12-15.

Basically my plan is to load all the gear into the life raft and drag it along until we could contact the mother base using the transmitter. It is not possible to walk 200 miles before the 200lbs of air runs out.
 
did not know this was the moon lol.......

15_ Box of matches (will not ignite)

5_ Food concentrate (probably could get by without it)

7_ 50 feet of nylon rope (by which to pull sled)

10_ Parachute silk

13_ Portable heating unit (if you are on the bright side of the sun and moving constantly this should not be a problem)

12_ Two .45 caliber pistols (I wonder if you could rocketjump with these puppies)

11_ One case dehydrated milk

2_ Two 100 lb. Tanks of oxygen (Buy yourself some time. Is that 100lbs on the moon or on the earth?)

1_ Stellar map of the moon?s constellation (Without this, you have no clue where to go)

6_ Life raft (depending on the sixe of the crew, you may need a sled to carry gear)

14_ Magnetic compass (this moon does not have a liquid core, thus no magnetic field)

3_ 5 gallons of water (the moon is a very dry place)

9_ Signal flares (the flares may have the oxidizer built-in, and not require atmospheric oxygen)

8_ First aid kit containing injection needles (what are you injecting?)

4_ Solar-powered FM receiver/transmitter (The mothership may be able to trangulate signal and send rescue rover. At very least, relay dying words to loved ones planetside.)


200 miles on the moon is not as far as it sounds: remember the reduced gravity on the moon and the amazing crap people can do when their lives are on the line. Also, if you are trained as an astronaut, you should be in incredible physical condition.

WTF?

"TEMPERATURE
The temperature on the Moon ranges from daytime highs of about 130°C = 265°F to nighttime lows of about -110°C = -170°F" - Text


 
with space suits on how will you drink or eat?

so the most important things are O2, map and Radio. the rest is just not needed.

Very true.... didnt think of that.

Modern space suits have in-suit drinking devices. Presumably any future sustained lunar mission would have upgraded suits to facilitate refills.

The constellation map is 100% useless. There is a good reason, but maybe I'll let you guys think about why 🙂

Because the map was created from the view of them on Earth?

Nope. It says it is a map of the moon's constellations... but really they'd be the same anyways, it's just the orientation of the poles (ie the north star) that would be different.

The more I think about this question the more stupid it seems.

typical 'unanswerable' story question. without knowledge of the conditions, you can't predict an outcome.

Personally my answer would be, "I'd do whatever protocol dictated, unless circumstances convinced me that protocol was incorrect or unnecessary". I mean, how can you go wrong? Ask a ridiculous question, get a ridiculous answer.

How about the moon is spinning.

unless of course, you know the exact time, the map is set for that time, and you know your specific declination.
 
pistols are useful - equal and opposite reaction in low gravity environment FTW.. i did this one a looooooooooooooong time ago

Not quite, but you're on the right track.

well it shouldn't be anything with North/South, because the constellations are never going to flip or anything.
 
It's because the moon's rotation is tidally locked to its revolution. That is, it takes 27.something days to go around the earth and 27.something days to rotate once about its axis. So a lunar day lasts about 2 earth weeks. The problems states you are on the lighted side of the moon, so it'll probably be a while before it gets dark 🙂
