Adapts to surroundings
Use energy as a producer or consumer
Does not grow or develop

Power supply
Mass limit
Financial cost
Science equipment
What is Astrobiology?
the study of life on Earth
the stars that harbor life
the potential for life elsewhere
the size and scope of the Universe
An example of an extremophile is:
an algae in an acidic lake
a polar bear in the tundra
a plant living in the savanna
an organism in the ocean
What is the difference between an acidophile and an alkaliphile?
Acidophile loves salt; Alkaliphile loves ice
Acidophile loves rocks; Alkaliphile loves dry
Acidophile loves radiation; Alkaliphile doesn’t
Acidophile loves acid; Alkaliphile loves base
What were the two most important limits you had to be aware of in order to effectively create your rocket?
Science Return & Cost
Power & Cost
Mass Limit & Cost
Science Return & Power
Based on your responses following the Astrobiobound engineering design phase, do you believe scientists get everything they desire when building a rocket for a mission such as this?
Yes
No
What is a more likely size of organism that may be found in the future?
Large
Small
If a mission was built to go to a planet, land, collect samples and data, and return to Earth, what would the budget for such a mission look like?
larger
smaller
the same as the $300M we were given
What would be an important hardware component for any return-to-Earth mission in the future?
A mobile lander
A secondary rocket
An oxygen supply
A drill & robotic arm
What is the most common element found in living organisms on Earth, and one we actively search for elsewhere?
Oxygen
Nitrogen
Carbon
Hydrogen
When a planet is neither too close, nor too far from its home star, it is said to exist in an area called the:
Asteroid belt
Oort Cloud
Kuiper Belt
Habitable Zone
Cells that evolved with nuclei are called
prokaryotes
panspermia
eukaryotes
adenosines
Tardigrades are also called as?
Algae
slime moulds
water bears
moss
Everything that exists, including all matter and energy. Mostly consists of empty space.
a galaxy
a black hole
the universe
the multiverse
What galaxy do we live in?
Andromeda Galaxy
Solar Galaxy
Milky Way Galaxy
Pinwheel Galaxy
I don't know
The Planet We Live on is
Sun
Earth
Mars
Saturn
Rock formations that are produced by a type of bacteria. The bacteria needs water, carbon dioxide, and sunlight to slowly make this rock.
stromatolites
biosignature
psychrophiles
halophiles
A moon of Jupiter that has the potential to support alien life. It has geysers which means that it could have an underground liquid ocean that is salty.
Ganymede
Titan
Europa
Perseverance rover
They are extremophiles that can grow and reproduce in low temperature ranging from -4 degrees to 50 degrees fahrenheit. They are found in places that are permanently cold and in the deep sea (on Earth).
biosignature
psychrophile
halophile
stromatolite
They are extremophiles that love salt. On Earth there are bacteria that are these and some types of algae (a plant). They have been found in the Great Salt Lake and the Dead Sea.
biosignature
psychrophile
halophile
stromatolite
The largest moon of Saturn and is the only moon in our solar system that has an atmosphere. It has rivers, lakes, seas, and may contain oceans (the liquid in these places is not water, but another type of liquid).
Ganymede
Titan
Europa
Perseverance rover
What is one reason we might not recognize life if we find it?
It could have oxygen as a biosignature.
It could have carbon dioxide as a biosignature.
We might not know what to look for, especially if it is very different from Earth life.
It could have complex carbon molecules as a biosignature.
Extraterrestrial (alien) life is likely to be different from Earth life because...
Earth-sized planets in the habitable zone are abundant in the universe
we lack the technology to recognize some potential biosignatures
the conditions on other planets are different from conditions on Earth
it could have oxygen as a biosignature.
Some scientists believe life is abundant in the universe because...
the conditions on other planets are different from conditions on Earth
the chemicals life is made of are abundant in the universe
all life requires liquid water
all life requires a source of energy
The Drake Equation answers the question...
"What is the number of detectable alien civilizations in the Milky Way?"
"How many people are picking their nose right now?"
"What is the shortest time to colonize the Galaxy?"
What is an exoplanet?
A planet that orbits a star other than the Sun.
The crunchy outer crust of a rocky planet.
An object that forms part of the asteroid belt between Mars and Jupiter.
A planet that used to be a star.
If you believe that we are the only planet with life on it then what would N equal in Drake's equation?
N=1
N=0
N=-1
N=2
What is the oldest known lifeform on Earth ?
cyanobacteria
mammals
invertebrates
reptiles
Why do scientists follow the water when looking for life in the solar system?
They believe that hydrogen is the foundation of all life.
They believe that water is essential for life on Earth.
Without the oxygen in water, life can't make food.
Photosynthesis requires water to produce energy.
What is the name of the planet in Avatar?
