Space

Low Earth Orbit, 120 miles above sea level, is where the majority of space exploration has occurred. This 1,100 mile band around Earth is where--for a cool $20 million--any private citizen can take the vacation of his or her life on the International Space Station. Commercial prospects for LEO are huge; but dangers lurk for any individual willing to travel here--radiation, cosmic rays, and space debris numbering in the thousands threaten any spacecraft travelling in orbit. It's the new frontier, or the final frontier...and the possibilities are endless if you are willing to travel to the edge of space exploration.

When man finally broke free of the Earth's gravitational pull the dream of travelling to other planets became a reality. Today scientists are proposing a bizarre array of technologies in the hope of travelling faster through space: from space craft sporting sails that catch laser beams, to propulsion engines powered by a bizarre entity known as anti-matter. Finally explore the science behind the seemingly fanciful notion of warp-drive and a theoretical particle that can travel faster than light.

Quinto sets out to discover whether aliens exist and what evidence we have to prove it. He meets with several who say they have encountered extra-terrestrial life–a man who has been abducted by aliens several times since childhood; a man who claims to have extracted an alien implant; and a woman who shows Zachary what it feels like to be abducted into a spacecraft.
Zachary also meets with the world's leading scientists at SETI in Green Banks, West Virginia. There, utilizing the world's largest telescope, they show him the methods they employ to communicate with potential other-worldly visitors and what this research has taught them about a mysterious radio signal they picked up 3 billion light years away.

One day, a cosmic disaster will make life on Earth impossible. To survive, we must find a new home amongst the stars. Scientists are already developing new propulsion systems to take us to these distant worlds.

The James Webb Space Telescope, a flagship observatory developed by NASA, the European Space Agency, and the Canadian Space Agency, is the largest space telescope ever built, with a deployable mirror measuring 21.3 feet (6.5 meters) in diameter and four scientific instruments to observe the universe in infrared wavelengths. The mission will study the formation of galaxies, stars, and planets. JWST was launched December 25, 2021 on an Ariane 5 ECA rocket.
This is the story of the James Webb Space Telescope, told by the people who have devoted their lives to it. It is the world’s most advanced and most expensive telescope, and building it has been fraught with challenges. But it will all be worth it if the mission is successful.

In space travel there is a saying that the first 50 miles and the last 50 miles are the most dangerous. Explore the controlled explosion of launch, the fiery crucible of re-entry and everything in between. See how a single spark inside a spacecraft or a micrometeoroid less than an inch wide hitting a space station can turn a routine mission into a lethal nightmare. As the missions become longer, venturing to Mars and beyond, the potential disasters will only become bigger. What would happen if a spacecraft ventured too close to a black hole or was hit by a gamma ray burst?
