What problems do astronauts face?

The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.

Why does NASA want to go to space?

The Lagrange point on the far side of the Earth-Moon system, called L2, also provides a “radio silence” zone for astronomical observations. Missions to translunar space will give NASA and its partners the opportunity to develop tools and operational techniques to support decades of future exploration, while remaining in relative proximity to Earth.

What are scientists doing in space today?

Today, for example, Stennis Space Center in Mississippi is conducting rocket engine testing in support of NASA’s exploration mission. At the Jet Propulsion Laboratory in California, scientists are reviewing information being sent back to Earth from distant reaches of the solar system, supporting the space science mission.

What are some negative consequences of space exploration?

Some negative consequences of space exploration include the emission of ozone-depleting substances and the presence of man-made debris in the earth’s orbit. In addition, astronauts may experience some negative physical effects of space exploration.

This is the beginning of a new era in space exploration in which NASA has been challenged to develop systems and capabilities required to explore beyond low-Earth orbit, including destinations such as translunar space, near-Earth asteroids and eventually Mars.

What is the importance of space exploration in human life?

Human 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.
