How might such drone usage be helpful in our lives?
Can you think of negative aspects about drone use?
Can you think of why drone use is being carefully monitored by the Federal Aviation Administration?
Scientists plan to study two identical twins in an out of this world experiment. Astronaut Scott Kelly, will leave on a space mission lasting one year at the International Space Station. His brother, Mark, who is also an astronaut, will remain on earth. Both will be involved in the same experiments to see the effects that long periods in space may have on the body. They are the only identical twin American astronauts(of the 2.25 million sets of American twins).For future long distance space missions such as Mars,which will take an estimated three years for the round trip, scientists want to study the effect of lack of gravity on human bones, the heart and other organs. Scott will travel to the ISS on March 28th, with another Russian astronaut(called cosmonaut in Russia) named Mikhail Kornienko. It will be the longest space time of any American astronaut.
Despite the experiments,you would have some "free" time. What would you do for a year in space? What would be three things you'd pack along to bring with you?
Other than family and friends, what would be some things you'd miss about being away from Earth?
