What is one goal of space exploration?
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
What are the dangers of space exploration?
The risks involved with space exploration include:
- micrometeorites – danger from impact damage (to spacecraft and to astronauts during spacewalks)
- solar flares and radiation – danger from ionising radiations.
- no atmosphere – we need air to breathe.
- space debris – danger from impact damage.
Why we should continue space exploration?
Space exploration also teaches us to be more sparing in our use of vital resources. Astronauts are trained to survive on limited quantities of food, raw materials, sunlight, energy, water and oxygen. And recycling in space is teaching us how to best implement a circular economy of resources.
How does space exploration affect medicine and health?
Advances in telemedicine, disease models, psychological stress response systems, nutrition, cell behavior and environmental health are just a few examples of benefits that have been gained from the unique space station microgravity environment.
What medical experiments are done in space?
Research on the ISS improves knowledge about the effects of long-term space exposure on the human body. Subjects currently under study include muscle atrophy, bone loss, and fluid shift. The data will be used to determine whether space colonization and lengthy human spaceflight are feasible.
Why doesn’t the Moon have an atmosphere?
Our Moon doesn’t have an atmosphere because it is too small and doesn’t have a strong magnetic field. Any atmosphere it might have had would be stripped away by the solar wind that barrages the small world. In contrast, our planet has more mass to hold its atmosphere close, and a strong magnetic field to protect it.
What is the atmosphere like on the moon?
The Moon has an atmosphere, but it is very tenuous. Gases in the lunar atmosphere are easily lost to space. Because of the Moon’s low gravity, light atoms such as helium receive enough energy from solar heating so that they escape in just a few hours.
