Life In Space –Extra-Terrestrial experiments

What are some examples ofexperiments that are

conductedon the ISS?

Answered by Ella G

The Effects of the gravity on the muscles of Zebra fish

•Our body designed for earth’s gravity.•No gravity in ISS, affects muscles.• Exercise and posture important in space to maintain muscles.•Trying to find if also occurs in Zebra fish.

Distrophila motility behaviour and ageing in space.

• Experiments to find if being in space affects behavior and age.•To see if human have side affects from being in space

Investigation of healing and growing bones in microgravity

using fishscales•Using goldfish scales to find responses in healing and growing bones in microgravity.•Once experiment done, compare results to Earth.

What do scientists hope to learn

about life in space?

Answered by Claire G

What do scientists hope to learn about life in space?

. The effects of being in space for long times

. How humans can adapt to life in space

. How different materials behave in microgravity eg: crystals, molten metals, liquid, foam and flames. how solid materials burn in space

What do scientists hope to learn about life in space?

. How to put out a fire in space using fuels, conditions, atmospheres, pressures and suppressants. How cell tissues, small plants and animals react in space .How/why does gravity influence growth/development of living things. How humans change in space – muscles, bones, organs and balance

How do scientists conduct experiments in space

•Scientist practice experiments on ground before in space.•They conduct practice mostly in deep pools because similar to being in space.•Early days animals were the beginning of conducting experiments.•Scientists are thinking of turning ISS into research lab.•Humans on earth give instructions while astronauts perform experiment in space•Prefer experiments when physically involvedMost Experiments Require•significant hands•changing frequencies•technology e.g.. Computers, Calculators etc.•Scientists on earths guidance •Significant materials

Name 2 findings that have emerged from experiments in

spaceAnswered by Bree

SEDA-AP (space environmental data acquisition equiptment – attached payload)

• Wanted to find way to measure space environment around ISS

• Created 7 small instruments placed around ISS• Found out that space atmosphere has vaccum

effect.• Now allows scientist to create safer spacecraft• Helping understand space changes and suns

activity

LOCAD-PTS (Lab-on-chip application development - portable test system

• Used to see if 5 second rule applies in space.• Results show in 5 seconds not much bacteria

is found• Now can analyze bacteria and fungi samples

on ISS• Helped crew in finding affective ways to clean

Interesting facts Scientists hope to make living on the ISS safer by• Finding info on space sicknesses• Why medication does not work same way as

on earth• Why red cells are produced and cleaned at

different rates• Experiments on crystals
