NASA spent billion Dollar for a Space Pen.

It was a rumor at late 1960s that "NASA is spending billions of Dollar only for a Space Pen". Yes it is true, because Astronaut were facing a problem to write in zero gravity in space. They had a problem with the pen which they brought with them. It was not working in zero-gravity. To overcome this problem NASA spent billions of dollar to make a ball point pen that would work in zero-gravity in space. Earlier the Russians use the pencil to solve this problem. But, this was not a good idea because pencil could break and need to be sharpen again and again which would create debris inside the space craft environment which is not an ideal situation to work.

                Paul Fischer, who later open the Fischer Space Pen Company stepped forward to solve this problem. He created the pen and pressurized it with 40psi (approx.) of Nitrogen gas and send some sample to NASA. They were impressed. Later Paul Fischer was asked to make more changes on it .So, that it would work in Vacuum , At --1200C and +1500C. These changes made pen to work in cold (shadow) and hot (direct sun light) in space.

• Finally A pen was ready to be use in zero gravity.
• The Fischer Space Pen being used by an Astronaut.

Massive Solar Eruption Captured By NASA

On 31 December NASA captured Massive Solar Eruption.This was the firework of sun. This solar flare was captured by NASA's Solar  Dynamic Observatory. This flare is called "Subdued" by Astronomer. 
These flare doesn't effect the earth but little bit the earth's magnetosphere. This happen at on new year, may be the celebration of sun as a new year fire work. 
According to NASA it happen in cycle of every 13 years or some says 11 years which was expected to happen next year. But, The Sun surprises every one by doing this. Scientist said this will not harm us anyway. It looks beautiful. Lets have a look in this video of massive solar eruption.


This flare rises up to  160,000 miles. 

Another video to see it from different view.

When this eruption happen the flare rises up to 160,000 from the surface of the sun and again came back to sun's surface due to its strong gravitational field.

Now, Another view of this eruption.
