The ISS experiences almost zero gravity. As a result, by using a centrifuge, it is possible to simulate a wide range of gravity conditions. The centrifuge can also imitate Earth’s gravity for comparison purposes, eliminate variables in experiments, and simulate the gravity on the Moon or Mars. This will provide information useful for future space travel.
Earth science
In the field of Earth science the ISS provides more opportunities for studying the AtmospHere and the Earth’s surface, helping us grasp the impact of our activities on the natural environment.
Engineering
Many of the new engineering technologies being developed on the International Space Station will lead to improved commercial space communication systems for personal phone, computer, and video use as well as automated maintenance functions and new lower-cost building construction techniques.
Astronomy/space science
Although the Hubble SpAce Telescope has sent back
invaluable information about space since its launch in 1990,
many questions about the universe remain that cannot be answered by using a telescope alone. The larger space on the
ISS allows a wider range of equipment to be used and so to
help answer some of the many questions that astronomers want answered. For example, more detailed studies of the way the Sun and the solAr wind affect the Earth’s mAgnetic field can now
be made. Such studies will improve forecasts of events ranging from the temporary disruption of telecommunicAtions to long-term alterations in climate.
Some experiments aboard the station will take place on the outsides of the station modules. Such exterior experiments can study the space environment and how long-term exposure to space, a vAcuum, and space debris affects materials. This research can provide future spacecraft designers and scientists with a better understanding of the nature of space and enhance spacecraft design.
