Fun Moments with Our Record Breaking Astronaut

Astronaut Scott Kelly has broken the record for longest time spent in space by a U.S. astronaut. He has spent a cumulative of 383 days in space over the course of four missions. What better way to celebrate than to highlight some of his fun moments on the internet:

A question from the president during a recent TweetChat:

Astronaut Scott Kelly occasionally hosts TweetChats from the International Space Station. During a recent chat, he happened to get a question from someone who lives at 1600 Pennsylvania Avenue! HERE’s a recap from a similar chat from the station. 

Tackling the tough questions during interviews:

During an interview with Katie Couric, Kelly explained what a day on the space station is really like…including the chores he can and can’t do. 

The pros and cons of having roommates:

The International Space Station is an orbiting laboratory where an international crew live, work and conduct valuable research. 

Getting supplies from cargo ships:

Living on the space station requires food, water and supplies. All of these things, plus experiments and other essentials are delivered to the crew via cargo ship. Learn more about our commercial resupply program HERE.

Comets have two tails.

There are two types of comet tails: dust and gas ion.

A dust tail contains small, solid particles that are about the same size found in cigarette smoke. This tail forms because sunlight pushes on these small particles, gently shoving them away from the comet’s nucleus. Because the pressure from sunlight is relatively weak, the dust particles end up forming a diffuse, curved tail.

A gas ion tail forms when ultraviolet sunlight rips one or more electrons from gas atoms in the coma, making them into ions (a process called ionization). The solar wind then carries these ions straight outward away from the Sun. The resulting tail is straighter and narrower. Both types of tails may extend millions of kilometers into space. As a comet heads away from the Sun, its tail dissipates, its coma disappears, and the matter contained in its nucleus freezes into a rock-like material.

Comets don’t like the sun.

Comets lose a lot of mass when they go by the Sun. A lot: some shed hundreds of tons of material per second. That’s actually a small fraction of the mass of a comet, but given time, and lots of solar passes, it adds up. Every comet we see is slowly dissolving in space. Eventually even the mighty Comet Halley will be gone, broken down into a swarm of rocks, gravel, and dust once its gas is gone.

It's a bird, it's a plane, no it's Hero,The Super Collie!

In Memory Of Neil Armstrong, Take A Moment To Wink At The Moon. Of all 12 astronauts to have stood on the lunar surface during the Apollo era, none are as popular as the first and most famous of the moon-walkers, Neil Armstrong. Described by his fellow Apollo 11 crew mate Buzz Aldrin as the “epitome of a space man”, Armstrong has served both before and after death as a cornerstone of NASA’s ethos-building force, one which has resonated since its inception 56 years ago. On August 25, 2012, Neil Armstrong passed away as the result of complications from a cardiovascular procedure. Following his death, Neil Armstrong’s family released a statement, which reads in part: “For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.” On this day, join us in celebrating the accomplishments and memorable career of Neil Armstrong by taking an opportunity to wink at the moon!
