OBJECTIVE:  I will begin to analyze how we might obtain each of the "BIG 5" requirements for human beings to survive and thrive on the planetduring today's class.

WORK O' THE DAY: 

SHORT day today:

• 7:30-8:10 1st period (40 minutes)

• 8:15-8:55 2nd period (40 minutes)

• 9:00-9:40 3rd period (40 minutes)

• 9:45-10:45 4th period (40-60 minutes)

  • Students who bought yearbooks will be released early from 4th period to pick them up in the commons, beginning at 10:25.

  • Running Start & other off campus students can pick their books up in the commons from 10:25 to 11:55. 

• 10:45-11:55 Common lunch and signing party (70 minutes)

  • All students will have the same extended lunch

• 12:00-12:40 5th period (40 minutes)

• 12:45-1:25 6th period (40 minutes)

• 1:30-2:00 Spring recognition assembly

Remember: Living in Antarctica! (But without air!)

A really good way to think about is to imagine living all day every day, every week, every month, every year in Antarctica -- with no air.

Remember! There's more, the gravity on is only about 1/3 the gravity on Earth. If you take your weight in pounds here on Earth and take 1/3 of that.... well, that's what it would feel like to walk around on the planet .

Additionally, there is a really uncomfy aspect of living on and that has to do with air pressure. We talked about that *at length* in our discussion of the solar system earlier this year.

Item #1: Shelter

• Issue #1: doesn't have a magnetic field so dangerous radiation from deep space and from the sun are constantly bathing the surface of the planet. It's not enough to cause severe damage right away but over time it definitely will.
• Issue #2: is very cold (Antarctica, remember?). Winter night temperatures even in the summer time are intensely cold: ~ -100 ^oF and in the winter even colder: ~-130 ^oF

• Issue #3: Mars air pressure is.... what? & why is that critical?

 

Many scenarios for living on Mars involve Lava Tubes --- huh? What's a lava tube and why do we care? (Please discuss)

 

 

 

 

 

When I was working at the Mauna Kea Observatory on the Big Island of Hawaii, a friend and I used to explore lava tubes. We'd start with a map of the island, find markers that said that lava tubes were present in some area, then find a topographical map and tromp around in the brush until we found a lava tube cave in.

We'd climb down into the tube and explore! It was pretty remarkable, we'd often turn off our flashlights (we each carried 2) and just stand quietly in the stillness, it was, to put it mildly, pretty intense at first simply because our eyes and ears TRIED to lock on to some sort of visual or audio anything... and couldn't!

 

Here's a photo I found online of a large lava tube on Earth:

Scientists are confident (although not certain) that the following structures are lava tubes on the moon:

Those structures are remarkably similar to what we see on the surface of :

 

With all that in mind, please work with your team to model how a lava tube could be turned into a ready-made structure.

Now work with your team to suggest how the other BIG 5 items could be incorporated into building a community inside a lava tube on

Now let's check in on a completely different strategy, sending a '3-d' printer to Mars and using it to build structures there.

 

We need to keep in mind that everything we need to take to is incredibly expansive so anything we don't have to take, any time we can use materials found there will be HUGE.
