Why do cats act so weird?/a>
This is the most beautiful picture
What's the coolest thing you've seen since you have been in space?
The Earth never fails to disappoint, but I’ve seen some pretty spectacular aurora from here.
tell the moon i love her
Dear moon, @324b2dun loves you. Happy Valentines!
Yes, I knew it
How was the food up there? Do you ever make sandwiches?
The food is ok. We use tortillas a lot to make space sandwiches.
What's the first thing you'll do when you come home?
I’ll give Amiko, Samantha and Charlotte a big hug.
Exercising in Space
Are you hoping to get to the gym more often in 2016? While you work out on Earth, here are a few ways that astronauts stay fit on the International Space Station.
Exercise is an important part of the daily routine for astronauts aboard the International Space Station to prevent bone and muscle loss, and to maintain cardiovascular health. On average, astronauts exercise two hours per day. The equipment they use in space is different than what we use on Earth.
Lifting 200 pounds on Earth may be a lot of work, but in microgravity a 200 pound dumbbell would not weigh anything. Therefore, free weights do not serve as a good strength training tool for the astronauts in space. That means exercise equipment needs to be specifically designed for use in space so astronauts will receive the workout needed.
What Equipment Do They Use in Space?
Advanced Resistive Exercise Device (ARED)
The ARED hardware uses adjustable resistance piston-driven vacuum cylinders along with a flywheel system to simulate free-weight exercises in normal gravity. It’s primary goal is to maintain muscle strength and bone mass in astronauts during long periods in space.
Cycle Ergometer with Vibration Isolation System (CEVIS)
CEVIS is very similar to a mechanical bicycle. It’s bolted to the floor, and astronauts snap their shoes on to the pedals. A seat belt can be used to hold them in position, and they can change the resistance for varying levels of difficulty.
Russian Treadmill (BD-2)
BD-2 is the treadmill that is found in the Russian segment of the space station. It allows crew members to walk and run with a speed from 2.4 to 20 km/hr.
Combined Operational Load Bearing External Resistance Treadmill (COLBERT)
COLBERT is the second generation U.S. treadmill on the space station. It features data collection devices that will allow scientists and doctors to evaluate how effective the exercise is in reducing the amount of bone and muscle density loss due to microgravity exposure. It allows crew members to walk and run with a speed from 4.8 to 20 km/hr.
Why is it called COLBERT?
The treadmill’s name was selected after comedian Stephen Colbert took interest in our online naming poll for Node 3 of space station. He urged his viewers to submit the name “Colbert.” Although we ended up choosing the suggested name “Tranquillity” for the node, we designated its new treadmill “COLBERT” in honor of the name that received the most entries.
VELO Ergomoeter Bike (VB-3)
VB-3 is used for aerobic training, medical tests and pedaling regimes. It is located in the Russian segment of the space station.

Vision & Microgravity...Can We See the Connection?
What do nutrition and genetics have in common? They could all be linked to vision problems experienced by some astronauts. We see people going up to space with perfect vision, but need glasses when the return home to Earth.
Why Does This Study Matter?
We want to be able to send astronauts to Mars, but losing vision capability along the way is a BIG problem. Discovering the cause and possible treatments or preventions will help us safely send astronauts deeper into space than ever before.
It’s Like Solving a Mystery
We already have an idea of why vision changes occur, but the real mystery remains…why do some astronauts have these issues, and other’s don’t?
Now, let’s break it down:
Nutrition is more than just what you eat. It includes how those things work inside your body. The biochemistry behind how your muscles make energy, how your brain utilizes glucose and how vitamins help with biochemical functions…it’s all part of nutrition.
Genetics also play a part in the vision changes we’re seeing in space. Data shows that there are differences in blood chemistry between astronauts that had vision issues and those that did not. We found that individuals with vision issues had different blood chemistries even before their flight to space. That means that some astronauts could be predisposed to vision issues in space.
Just in January 2016, scientists discovered this possible link between genetics, nutrition and vision changes in astronauts. It makes it clear that the vision problem is WAY more complex than we initially thought.
While we still don’t know exactly what is causing the vision issues, we are able to narrow down who to study, and refine our research. This will help find the cause, and hopefully lead to treatment and prevention of these problems.
Fluid Shifts
The weightless environment of space also causes fluid shifts to occur in the body. This normal shift of fluids to the upper body in space causes increased inter-cranial pressure which could be reducing visual capacity in astronauts. We are currently testing how this can be counteracted by returning fluids to the lower body using a “lower body negative pressure” suit, also known as Chibis.
Benefits on Earth
Research in this area has also suggested that there may be similarities between astronaut data and individuals with a clinical syndrome affecting 10-20% of women, known as polycystic ovary syndrome. Studying this group may provide a way to better understand vision and cardiovascular system effects, which could also advance treatment and prevention for both astronauts and humans on Earth with this disease.

It is a wonderful opportunity, the possession of leisure.

CLASSIC OF THE DAY:
A Room with a View by E.M. Forster
Romantic comedy this is not. The rosiness of a woman stumbling upon convenient fantasy fulfillment by marrying into privilege and bourgeois wealth do not tinge the themes of this classic. Rather this aspires to the novelty of a sort of female bildungsroman. A woman who is roused into the acknowledgement of her desires and self through the unwitting intervention of men considered unworthy of being even good travel companions - how many male authors/poets/dramatists of Forster’s generation have cared enough about class distinctions and gender inequality to fashion such a narrative?
Sexually and emotionally inhibited young woman savoring personal liberty for the first time through the love of a man of inferior social standing who assumes a consciously passive role in earning her affections - this was, perhaps, Forster’s way of contradicting and affirming Austenian values at the same time. The very possibility of the intersection of marital bliss and lack of wealth and connections in a prospective husband and disregard for societal approval lay well outside the limits of Austen’s imagination but she did endow her many women characters with enough dimensions to be keenly distinguishable from each other.
What else is there to say? Here’s to the unexpected joy of discovering another male author of the last century, who was effortlessly free of the abysmal sexism that is so regrettably palpable in the work of many novelists (of all genders) of the present. Here’s to a great story-teller who ventured beyond the narrow horizons conferred on him by his times.

Life is easy to chronicle, but bewildering to practice.
