THIS. Thank You.

Can’t not reblog it

New Rule

Nobody can be mean to Steve anymore ok.

MY BADASS BOY

I’m not ready for this

Thank you to the best fans in the universe! Marvel Studios’ “Avengers: Infinity War” Trailer TOMORROW.

Two Steps Forward in the Search for Life on Mars

We haven’t found aliens but we are a little further along in our search for life on Mars thanks to two recent discoveries from our Curiosity Rover.

We detected organic molecules at the harsh surface of Mars! And what’s important about this is we now have a lot more certainty that there’s organic molecules preserved at the surface of Mars. We didn’t know that before.

One of the discoveries is we found organic molecules just beneath the surface of Mars in 3 billion-year-old sedimentary rocks.

Second, we’ve found seasonal variations in methane levels in the atmosphere over 3 Mars years (nearly 6 Earth years). These two discoveries increase the chances that the record of habitability and potential life has been preserved on the Red Planet despite extremely harsh conditions on the surface.

Both discoveries were made by our chem lab that rides aboard the Curiosity rover on Mars.

Here’s an image from when we installed the SAM lab on the rover. SAM stands for “Sample Analysis at Mars” and SAM did two things on Mars for this discovery.

One - it tested Martian rocks. After the arm selects a sample of pulverized rock, it heats up that sample and sends that gas into the chamber, where the electron stream breaks up the chemicals so they can be analyzed.

What SAM found are fragments of large organic molecules preserved in ancient rocks which we think come from the bottom of an ancient Martian lake. These organic molecules are made up of carbon and hydrogen, and can include other elements like nitrogen and oxygen. That’s a possible indicator of ancient life…although non-biological processes can make organic molecules, too.

The other action SAM did was ‘sniff’ the air.

When it did that, it detected methane in the air. And for the first time, we saw a repeatable pattern of methane in the Martian atmosphere. The methane peaked in the warm, summer months, and then dropped in the cooler, winter months.

On Earth, 90 percent of methane is produced by biology, so we have to consider the possibility that Martian methane could be produced by life under the surface. But it also could be produced by non-biological sources. Right now, we don’t know, so we need to keep studying the Mars!

One of our upcoming Martian missions is the InSight lander. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the “inner space” of Mars: its crust, mantle, and core.

Finding methane in the atmosphere and ancient carbon preserved on the surface gives scientists confidence that our Mars 2020 rover and ESA’s (European Space Agency’s) ExoMars rover will find even more organics, both on the surface and in the shallow subsurface.

China..you’re doing it right.

There were times when I respected every pairing with Steve but some people in Steve/Bucky fandom made it impossible. Every pairing has its problems but they at least accept that Steve can have a character outside of romance. With stucky its impossible for Steve to be more then a horny teenager. No other motivation in his life - no freedom, no justice, no helping people, no real friendship. Everything in his life is about Bucky. Who could have thought that he was actually one of the greatest CB characters?

Okay but can we talk about the beautiful symmetry of the Captain America movies for a second

Steve picks up the shield and becomes Captain America because of Bucky

Steve lays down the shield and stops being Captain America because of Bucky

Steve Rogers + the ‘Captain America" fandom

Steve/Tony + complementary qualities

male writers writing male characters: This Bruce Killshot. He has over 10000 confirmed kills and is the top leading spy in the Super Hard To Get In Spy Organization Of The World. He is a master of every martial art and can use virtually any weapon with ease. He’s not only a Real Gruff Man but a Ladies man who smokes cigars while Having Sex With Beautiful Women but he never gets attached. He’s a hard Whiskey Drinking Man who once killed an elephant with a toothpick and bottle of glue.

Men: this is so realistic wow such a complex character….

A woman: This is Angela she’s the chosen one of this story and has a natural knack for magic and can-

men: this fucking self insert mary sue this is fucking trash are you kidding me 

Uh, I'm so envious of people who know what they want from life. She is so young and already so sure of herself. And here I am who is supposed to be a grown up woman well on the way to her 30s and I actually have no clue. People like her are an inspiration

Now at the age of 13, she had already: Attended Space Camp 7 times, Space Academy 3 times and Robotics Academy 1 time. Became the first person to complete all the NASA Space Camps in the world, including Space Camp Turkey and Space Camp Canada. Witness 3 Space Shuttle launches. Attend Sally Ride Camp at MIT, and three Sally Ride Day camps. Speak several foreign languages: Spanish, French, Chinese and some Turkish. She also delivers motivational speeches to other children.

She is determined to be the first person to land on Mars & NASA is already training her.
