National Aeronautics and Space Administrion

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos. Check out our "Thinking About NASA History" folder online as an introduction to how history can help you.

Could One of these Planets be the Home of ET

The most Earth like planets are often not the most welcoming for life. There doesn't have to be water as we know it present.

Titan, Mars then Gliese 581D filial Earth in ability to support life. Titan has a vast lake of liquid hydrocarbons and has a surface temperature of negative 300 degees.

Gleise 581D is the only exo-solor planet astronomers consider Earth-like because it is rocky and orbits a cool dim star.

Like no other planet

Scientist find a world like no other. It's a steamy waterworld, which was discovered in 2009. It's in the area of space GJ1214b.

This planet is as light and airy as Styrofoam but as dense as iron. It orbits two suns in the constellation of Ophiuchus.

Its size is 2.7 times Earth's diameter. It weighs 7 times as much. The star it orbits is red dwarf, at 1.2 million miles.away. It is a whopping 446 degrees. It's composed of a water like substance, that can withstand that heat. It's surface represent our world, for it has a lot more liquid than rock. This planet once experienced earth like temperatures and it formed from a star where water ice.was plentiful.

The James Webb telescope, which is to be launched in 2018 will let us see it better. The high temperature and pressure create hot ice and.superfluid water which are completely alien to us.

Supernovas and Stardust

Supernovas and Stardust

A supernova is the biggest event in the universe. They take place vast distances from Earth. There a way we see our connection.

A supernova occurs when a star runs out of fuel and emploeds on itself or when it links inself with neighbouring stars and also causes a blackhole to occur. It is the grandest display of a lifecycle. The supernovas make the equivalent of energy, as the stars whole life. The good thing is understanding that these materials are a part of us.

There is a shockwave that shoots out of a star when it explodes. Compressed gas and space triggers this shockwave. We start seeing spiraling effects of materials being expelled from the dying star. This recycles the energy within the universe. These little bits of dust begin a process called ecreation.

The snowball effect takes off causing it to grow enormous eventually forming stars, planets or moons. It then collapses to the size of the Earth and smaller still within about a second.

Think about how many star elements have went nova to create your body. It is estimated that at least 93% of your body is stardust.

Mars and Earth have a ping-pong game going on with materials which is known as pan-spermia. We are a significant part of the cosmos. To end this I have a quote from Carl Sagan
"Matter is much older then life. Billions of years before the Sun and Earth even formed, atoms were being synthesized in the insides of hot stars and they returned to space when the stars blew themselves up. Newly formed planets were made out of the stellar debris, and Earth and every living thing, are made of star stuff."

Virgin Galactic: 200,000 Ticket to ride

Record executives want to send JZ and Beyonce to space to simply make a music video. The idea itself is of historical value. It sounds off the wall now, because now there is nothing to really compare to it.

Space tourism is actually a real concept. This concept is actually in the making. This puts some competition within the governments for the funding of the space programs.

6.2 miles is the "carmen line," where the atmosphere ends and space begins. 470 tickets have already been sold, without an actual date being set. It's the first sub-orbital flight which is pretty ground breaking.

The director of X-men is going up with Brad Pitt and Angelina Jolee, along with Stephan Hawkings, Selma Hiat, and Tom Hanks. Surprisingly William Shatner is not going. A plane will take the passengers to a mothership, 300,000 feet above the Earth.

It cost 20,000 to reserve a ticket and 200,000 to go. You will need 3days of G force training. It will take 150 minutes to fly. It is very stressful on the body, as you hurdle through space at the speed of light within 30 seconds.

Space tourism is becoming the next big thing. When you see the Earth out side the window you see how inter-connected we all are. A good comparison is to the flight of a shuttlecock in badmitten.
