10 Accommodations for Space Travel Presentation Notes

8 Why do astronauts wear space suits in swimming pools before participating in manned space explorations? F It allows them to work in a frictionless environment. G Gravity of water is similar to microgravity of space. H The load of the backpack is lightened by water, allowing astronauts to more easily practice space tasks. J Wearing a spacesuit in water simulates the weightlessness of space. 7 The insulated feature of space suit layers are designed to - A protect from radiation. B trap excessive CO2. C regulate temperature. D provide pure O2. 6 How does the space suit backpack help astronauts breathe in a space environment? F It maintains air pressure to keep bodily fluids from boiling. G It provides pure O2 for inhaling and canisters to collect CO2. H It stabilizes and internal temperature of 22◦C (72◦ F). J It collects urine and solid wastes. 9 How does pressure in the astronaut’s space suit help the body work? A The suit forces blood to certain parts of the body to counteract the absence of gravity. B The suit acts as an external pacemaker to regulate the heartbeat. C The suit regulates gas exchange between the

• xygen pack and the

astronaut. D The suit monitors the amount

• f O2 to CO2 in the blood.

11 Accommodations for Space Travel Presentation Notes

10 All of the following are ways that atmosphere makes the existence of life

• n Earth possible EXCEPT -

F It shields the Earth from collisions. G It offers protection from radiation. H It maintains a constant temperature. J It allows for gas exchange between plants and animals. 11 When NASA sends probes to distant planets they will normally go to another planet first, even though the probe will not collect any data from the first planet. Why do they do this? A To take pictures of both planets B To make the trip longer C To shorten the trip using the first planet’s gravity to slingshot the satellite. D NASA does not do this.
