Bellwork 12/12 If you could go to space to study something, what might you want to study? Explain your answer. Given the opportunity…would you travel to space?

Article Discussion Find a small group of no more than 4 people, grab a large whiteboard & marker. Take your article with you! Discuss all of the questions with your group Outline your responses to #1, #4, & #6 on your whiteboards Please, be prepared to share out your discussion points 

Space Environment Almost a perfect vacuum Extremely thin gas clouds 1 atom/cm3 Immense temperature range Facing the sun: 120⁰C Shaded from the sun: lower than -100⁰C

Matter in Space Because there is so little matter in space… No sound Heat cannot be transferred via conduction or convection Pressure is nearly 0kpa What kind of effects would this pressure change have on the human body?

Human Body in Space Would you freeze immediately? Probably not…heat transfer is tough in space!

Human body in space: Suffocation…but not like we think of it on Earth Oxygen would “reverse-dissolve” & would rush out of your lungs Hypoxia Why?

Human Body in Space Dissolved gases in bodily fluids would expand Ebullism Your body would swell as the liquids turned to vapor Why? https://www.youtube.com/watch?v=ejlKsj7k4Rc

Human Body in Space Sunlight UV radiation Damage/destroy your retinas Absolutely no protection from UV rays Massive sunburn (short term) DNA & cellular mutations (long term)

How long could you actually survive in space? https://www.youtube.com/watch?v=RjkrqMm52JI

Bellwork 12/14 What do you know about the International Space Station? If you could ask someone living on the International Space Station some questions, what would you ask?

So…how can we protect astronauts in space?? Space Suits! More than just “astronaut clothes” Fully equipped, one-person space craft Extravehicular Mobility Unit (EMU) Different types Inside or outside of the vehicle? Type of Atmosphere (Moon, Space Station, ect)

So, what would it be like to actually live in space…? Let’s find out!

What is a Space Station? a large artificial satellite used as a long-term base for manned operations in space

Space Stations: First space station: Salyut 1 (1971)—Russian U.S. launches Skylab in 1973 Several other Salyut & Skylab missions were launched after that Mir space station launched in 1986

International Space Station (ISS) First piece of the ISS launched in 1998 First crew arrived in 2000 Finished in 2011

Components of the ISS Over 70 major components Canadian Robotic arm (Canadarm) Space walks, repairs, experiment monitoring 6 laboratories 2 U.S (NASA) 1 European Space Agency 1 Japanese 2 Russian

How does the ISS work? Pressurized modules Solar panels Heat produced from electronics Oxygen: Created from water through electrolysis Deliveries from Earth Carbon Dioxide: Removed by scrubbers

Water & Food Supply Water is delivered from Earth Recycle water from: Breath Fuel processing Urine/Waste Food is dehydrated and delivered via spacecraft

Importance of the ISS: Humans have been perpetually living in space since 2000 Allows for long-term space experimentation First step toward testing habitability further into space “Spinoff” technologies that benefit Earth https://spinoff.nasa.gov/Spinoff2008/tech_benefits.html

What is the ISS working on right now? Some of the experiments being done… Space medicine 3-D printing in space “Veggie” plant program Created by ORBITEC (in Madison, WI ) https://www.nasa.gov/content/veggie-plant-growth-system-activated-on-international-space-station http://www.nasa.gov/mission_pages/station/research/news/3D_in_space

Spot The Space Station! http://spotthestation.nasa.gov/sightings/view.cfm?country=United_States&region=Wisconsin&city=Madison#.VVHxrflViko Follow the ISS on Twitter! https://twitter.com/space_station

What is it like to live on the ISS? https://www.youtube.com/watch?v=hyn1We0wOT8 Suni Williams American Astronaut & US Navy Officer Record for longest space flight & most space walks by a woman

Worktime: You will now have time to conduct some independent research to start piecing together some mission project ideas. There are two documents in the Google Classroom… Space Suit Design (Choose one research option) Space Settlement Research (Just the “Orbital Colony” section)

Exit Slip: Take out a sheet of paper: What did you find surprising or confusing about the ISS? How would life on the ISS be different from life on a permanent habitat? What kinds of ideas can you take away from this video to consider/incorporate into your project?
