What are Extravehicular Mobility Units? What are they made of? |
A small spacecraft that protects the astronaut while in space. There are three main sections to the suit; the inner suit, the outer suit, and the backpack. |
|
|
What is the inner suit in Extravehicular Mobility Units used for? |
Covers the whole body except the hands, feet, and head. There are tubes of flowing water woven into the clothes to keep the astronaut cool (Regulate body temperature). |
|
|
What is the outer suit in Extravehicular Mobility Units used for? |
Protects astronaut from space dust that travels around the speed of a bullet. Provides a constant, ideal temperature and pressure. Visor on helmet is gold to protect eyes. |
|
|
What is the backpack in Extravehicular Mobility Units used for/contain? |
Holds oxygen and fans to move the oxygen, drinking water and cooling water (cooling water for tubes in inner suit), a carbon dioxide removal system, and supplies electricity for the suit. |
|
|
what is SAFER used for? where is it located? |
SAFER is located on the back of an astronaut's space suit. It has several small thruster jets. If the astronaut happened to float away, he/she would use the thruster jets on SAFER to get back to the ship. |
|
|
What does ECLSS stand for? |
Environmental Control Life Support System. |
|
|
What is Enceladus? |
Global ocean on Saturn's moon |
|
|
What are the layers of Enceladus? |
First (Outer) layer- Icy crust Second layer- Global ocean Third (center) layer- Rocky core |
|
|
What is the difference between astrophysics and space physics? |
Astrophysics- Things that we can't reach. (Farther from is) Space physics- Things that we can get to and study. (closer to us) |
|
|
What are the three main parts of rockets? |
1. structure 2. payload 3. fuel |
|
|
Reflecting Telescopes |
They use mirrors to focus light at focal point. They use concave mirror. |
|
|
Refracting telescopes |
Uses two lenses to focus the light. |
|
|
Interferometry |
the applied science of combining two or more input points of a particular data type, such as optical measurements, to form a greater picture based on the combination of the two sources. |
|
|
What are satellites? |
An artificial body placed in orbit around the earth or moon or another planet in order to collect information or for communication. |
|
|
How do satellites work? |
They transmit signals from one side of the earth to another. A ground-based satellite transmitter dish beams a signal to the satellite's receiving dish |
|
|
What do people need to survive in space? |
Oxygen, water, food, shelter, electricity, waste disposal system, and if they really wanted: gravity. |
|
|
How would they get these things? |
Oxygen: They can use a system of splitting a water molecule into oxygen and hydrogen Water: they can purpose water from pee and space water Food: Preprepared Shelter: titanium and high end steel, its light weight and strong Electricity: solar panels Waste Disposal: dump overboard and liquid evaporates Gravity: Spinning the ship created artificial gravity |
