Detailed explanation-1: -With our current technology, travel to the closest star in another solar system is not possible for a human crew due to what limitation? Inability to store food and water for long periods of time.
Detailed explanation-2: -The Hubble Space Telescope Being 569 km above the Earth’s surface, this technology avoids atmospheric distortion, allowing it to bring thousands of jaw-dropping images back to Earth. Additionally, it has helped explain many of the greatest space mysteries.
Detailed explanation-3: -A major issue with traveling at extremely high speeds is that due to the requisite high relative speeds and large kinetic energies, collisions with interstellar dust could cause considerable damage to the craft. Various shielding methods to mitigate this problem have been proposed.
Detailed explanation-4: -The Hubble Space Telescope makes one orbit around Earth every 95 minutes.
Detailed explanation-5: -For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300, 000 kilometers per second (186, 000 miles per second).
Detailed explanation-6: -Spacecrafts must provide their passengers with oxygen to breathe. Spacecrafts carry their own sources of oxygen and nitrogen. These gases are circulated throughout the spacecraft to provide similar air to the one we breathe on Earth. Astronauts must also carry their entire food supply when they travel to space.
