That Time We Flew Past Pluto…

Two years ago today (July 14), our New Horizons spacecraft made its closest flyby of Pluto…collecting images and science that revealed a geologically complex world. Data from this mission are helping us understand worlds at the edge of our solar system.

The spacecraft is now venturing deeper into the distant, mysterious Kuiper Belt…a relic of solar system formation…to reach its next target. On New Year’s Day 2019, New Horizons will zoom past a Kuiper Belt object known as 2014 MU69.

The Kuiper Belt is a disc-shaped region of icy bodies – including dwarf planets such as Pluto – and comets beyond the orbit of Neptune. It extends from about 30 to 55 Astronomical Units (an AU is the distance from the sun to Earth) and is probably populated with hundreds of thousands of icy bodies larger than 62 miles across, and an estimated trillion or more comets.

Nearly a billion miles beyond Pluto, you may be asking how the spacecraft will function for the 2014 MU69 flyby. Well, New Horizons was originally designed to fly far beyond the Pluto system and explore deeper into the Kuiper Belt. 

The spacecraft carries extra hydrazine fuel for the flyby; its communications system is designed to work from beyond Pluto; its power system is designed to operate for many more years; and its scientific instruments were designed to operate in light levels much lower than it will experience during the 2014 MU69 flyby.

What have we learned about Pluto since its historic flyby in 2015?

During its encounter, the New Horizons spacecraft collected more than 1,200 images of Pluto and tens of gigabits of data. The intensive downlinking of information took about a year to return to Earth! Here are a few things we’ve discovered:

Pluto Has a Heart

This image captured by New Horizons around 16 hours before its closest approach shows Pluto’s “heart.” This stunning image of one of its most dominant features shows us that the heart’s diameter is about the same distance as from Denver to Chicago. This image also showed us that Pluto is a complex world with incredible geological diversity.

Icy Plains

Pluto’s vast icy plain, informally called Sputnik Planitia, resembles frozen mud cracks on Earth. It has a broken surface of irregularly-shaped segments, bordered by what appear to be shallow troughs.

Majestic Mountains

Images from the spacecraft display chaotically jumbled mountains that only add to the complexity of Pluto’s geography. The rugged, icy mountains are as tall as 11,000 feet high.

Color Variations

This high-resolution enhanced color view of Pluto combines blue, red and infrared images taken by the New Horizons spacecraft. The surface of Pluto has a remarkable range of subtle color variations. Many landforms have their own distinct colors, telling a complex geological and climatological story.

Foggy Haze and Blue Atmosphere

Images returned from the New Horizons spacecraft have also revealed that Pluto’s global atmospheric haze has many more layers than scientists realized. The haze even creates a twilight effect that softly illuminates nightside terrain near sunset, which makes them visible to the cameras aboard the spacecraft.

Water Ice

New Horizons detected numerous small, exposed regions of water ice on Pluto. Scientists are eager to understand why water appears exactly where it does, and not in other places.

Pi Guides the Way

It may be irrational but pi plays an important role in the everyday work of scientists at NASA. 

What Is Pi ?

Pi is the ratio of a circle’s circumference to its diameter. It is also an irrational number, meaning its decimal representation never ends and it never repeats. Pi has been calculated to more than one trillion digits, 

Why March 14?

March 14 marks the yearly celebration of the mathematical constant pi. More than just a number for mathematicians, pi has all sorts of applications in the real world, including on our missions. And as a holiday that encourages more than a little creativity – whether it’s making pi-themed pies or reciting from memory as many of the never-ending decimals of pi as possible (the record is 70,030 digits).

While 3.14 is often a precise enough approximation, hence the celebration occurring on March 14, or 3/14 (when written in standard U.S.  month/day format), the first known celebration occurred in 1988, and in 2009, the U.S. House of Representatives passed a resolution designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi.

5 Ways We Use Pi at NASA

Below are some ways scientists and engineers used pi.

Keeping Spacecraft Chugging Along

Propulsion engineers use pi to determine the volume and surface area of propellant tanks. It’s how they size tanks and determine liquid propellant volume to keep spacecraft going and making new discoveries. 

Getting New Perspectives on Saturn

A technique called pi transfer uses the gravity of Titan’s moon, Titan, to alter the orbit of the Cassini spacecraft so it can obtain different perspectives of the ringed planet.

Learning the Composition of Asteroids

Using pi and the asteroid’s mass, scientists can calculate the density of an asteroid and learn what it’s made of–ice, iron, rock, etc.

Measuring Craters

knowing the circumference, diameter and surface area of a crater can tell scientists a lot about the asteroid or meteor that may have carved it out.

Determining the Size of Exoplanets

Exoplanets are planets that orbit suns other than our own and scientists use pi to search for them. The first step is determining how much the light curve of a planet’s sun dims when a suspected planets passes in front of it.

  • what she means: Iroh, though. He could’ve stayed in the Fire Nation and lived a cushy life. He could’ve had whatever he wanted - a comfortable home, a slew of servants, a tea shop - any retiree’s dream following a long, highly successful career in a war. He could’ve been mostly happy and mostly content, free to do whatever he pleased really as the Fire Lord’s brother and a former general. He didn’t have to do any of the things he did for Zuko. He really didn’t. Zuko wasn’t even his kid! But guess what? Iroh loved Zuko like his own son. And Iroh left everything he knew to follow this asshole of a kid around the world on a pointless mission all the while loving him like Zuko had never been loved before and I just... Iroh, though.

It’s International Asteroid Day!

There are more than 700,000 known asteroids, but how much do you know about these rocky remnants left over from the birth of our solar system 4.6 billion years ago? 

Today, June 30 is International Asteroid Day. Here are some things to know about our fascinating space rubble.

1. A Place in Space 

Asteroids—named by British astronomer William Herschel from the Greek expression meaning “star-like"—are rocky, airless worlds that are too small to be called planets. But what they might lack in size they certainly make up for in number: An estimated 1.1 to 1.9 million asteroids larger than 1 kilometer are in the Main Belt between the orbits of Mars and Jupiter. And there are millions more that are smaller in size. Asteroids range in size from Vesta—the largest at about 329 miles (529 kilometers) wide—to bodies that are just a few feet across.

2. What Lies Beneath 

Asteroids are generally categorized into three types: carbon-rich, silicate, or metallic, or some combination of the three. Why the different types? It all comes down to how far from the sun they formed. Some experienced high temperatures and partly melted, with iron sinking to the center and volcanic lava forced to the surface. The asteroid Vesta is one example we know of today.

3. Small Overall 

If all of the asteroids were combined into a ball, they would still be much smaller than the Earth’s moon.

4. Except for a Big One

In 1801, Giuseppe Piazzi discovered the first and then-largest asteroid, Ceres, orbiting between Mars and Jupiter. Ceres is so large that it encompasses about one-fourth of the estimated total mass of all the asteroids in the asteroid belt. In 2006, its classification changed from asteroid to  as a dwarf planet.

5. Mission to a Metal World 

NASA’s Psyche mission will launch in 2022 to explore an all-metal asteroid—what could be the core of an early planet—for the very first time. And in October 2021, the Lucy mission will be the first to visit Jupiter’s swarms of Trojan asteroids.

6. Near-Earth Asteroids

The term ‘near’ in near-Earth asteroid is actually a misnomer; most of these bodies do not come close to Earth at all. By definition, a near-Earth asteroid is an asteroid that comes within 28 million miles (44 million km) of Earth’s orbit. As of June 19, 2017, there are 16,209 known near-Earth asteroids, with 1,803 classified as potentially hazardous asteroids (those that could someday pose a threat to Earth).

7. Comin’ in Hot 

About once a year, a car-sized asteroid hits Earth’s atmosphere, creates an impressive fireball, and burns up before reaching the surface.

8. But We’re Keeping an Eye Out

Ground-based observatories and facilities such as Pan-STARRS, the Catalina Sky Survey, and ATLAS are constantly on the hunt to detect near-Earth asteroids. NASA also has a small infrared observatory in orbit about the Earth: NEOWISE. In addition to detecting asteroids and comets, NEOWISE also characterizes these small bodies.

9. Buddy System

Roughly one-sixth of the asteroid population have a small companion moon (some even have two moons). The first discovery of an asteroid-moon system was of asteroid Ida and its moon Dactyl in 1993.

10. Earthly Visitors 

Several NASA space missions have flown to and observed asteroids. The NEAR Shoemaker mission landed on asteroid Eros in 2001 and NASA’s Dawn mission was the first mission to orbit an asteroid in 2011. In 2005, the Japanese spacecraft Hayabusa landed on asteroid Itokawa. Currently, NASA’s OSIRIS-REx is en route to a near-Earth asteroid called Bennu; it will bring a small sample back to Earth for study.

Au idea where

Person a is a werewolf. With silver fur. Literally. They have fur of silver, every strand coated in the metal, from muzzle to tail.

Person b is a vampire, and vampires can’t, y'know, TOUCH silver… Not without burning.

Now imagine the two have to work together for a mission: find a lost friend, retrieve an important artifact/antidote, unite their countries, save the world, whatever. A mission wherein they have to be in close quarters with each other. And they have to accomplish it all without touching each other

(Bonus: person a doesn’t think twice about burning themselves extensively to save person b’s sorry butt from certain death)

anonymous asked:

Dai romances react to the first time the inquisitor kisses them in an affectionate way/on the forehead? Iv been cryin thinkin bout how bull and Dorian and like a lot of the crew have only ever had experience in like purely sexual relationships and have never like had someone love them like that

Cassandra: She flushes. It’s almost impossible not to. By now there’s no doubt that they hold each other in no little affection, and there is still a part of her -the part of her that will always revel in romance- that always cherishes the few moments they are able to sneak away for a brief kiss or tender moment above the forge. But the first time he raises her hand to place a kiss on her knuckles, eyes sparkling as he looks up at her with humor and yet also with an adoration that steals her breathe? She flushes scarlet, and her heart skips a beat as she is swamped with emotion.

Solas: The first time he feel soft brush of her lips against the curve of his ear she is leaving from a meeting with Leliana and he is laying the groundwork for his next mural. The line of the brush jumps as he does, surprised by the brief moment of affection, but even though he must scrape the mistake from the fresco and start again Solas cannot find it in his soul to be frustrated. Rather it is endearing in it’s own way and it brightens hm for the rest of the day.

Sera: She’s got both hands and her teeth involved in tying the fletching on her next batch of arrows, and yet it never crosses her mind that using her teeth as a cutting instrument have limited her affection access until her lover drops a kiss on the tip of her nose. She almost topples over form surprise, but then the Red Jenny bursts out laughing and tackles her Inqy with a kiss of her own. It’s the sweetest thing anyone has ever done for her, and it becomes their thing for mornings or greetings.

Blackwall: Carving can put knots like no one would believe in the arms and shoulders, and no amount of kneading can stop the pain in muscles that he can’t reach on his own. But the first time his lady massages those tension knots from him the warrior all but collapses into a puddle. And when she presses a kiss to the center of his shoulder blades, for those moments when she cannot be there to make the tension stop, his heart almost bursts. And Blackwall will carry the sensation of it for hours afterwards, a smile carved onto his face.

Iron Bull: It’s funny, sometimes, how much taller he is than his Kadan. Even if they are qunari his horns and sheer size puts him over most. And so the almost frustrated huff the Inquisitor gives him when they are preparing to leave makes him laugh and go to pat their head. And yet the kiss they place on the inside of his wrist stops that cold. It could be sexual- should be sexual, would be in any other relationship-, but with them…it’s more. It’s affection and promise, love and something that is simply theirs all rolled into one. Later he will find himself rubbing the spot for hours, mind running a thousand miles an hour but with a smile on his face.

Dorian: He loves his amatus. He does, loves him truly and deeply and anyone who says otherwise will meet the altus to face that insult. The hours he spends with the Inquisitor are some of the best in his life, and every affectionate moment washes clear some of the fear and loneliness he thought he would always carry. And for that the ‘vint will always be grateful. But he is also a scholar, and when his focus is on something it can be hard to shake loose. He is aware that his amatus has come to bid him farewell before another turn in the field, and he is going to look up from his book any second to give them a proper send off, he is– but then he hears the other man chuckle, and suddenly the Inquisitor has bent down to press a kiss to the crown of his head, a gentle bit of pressure where his hair parts. And while the necromancer playfully swats them away and insists on giving them a proper send off later he will sit in his chair, fingers running tiny circles around the spot, and wonder at this love that he has found.

Josephine: A diplomat’s work is never finished, and it is to Lady Montilyet frustration that she can never carve out enough free time to spend with her love as she would like. Between their constant world missions and her drive to make sure said missions are funded their paths do not often cross. And so she is delighted when they wander into her office with a tray and an offer to split the duties of letter writing– especially as there are some nobles who would be far more helpful after receiving something in the herald’s own hand. And while the gentle kiss that they press to her temple as they collect their half of the work is new, it immediately seems right. And if she spends the next ew days brushing her fingers across it and sighing no one needs to know why but her.

Cullen: There were times, particularly near the end of his tenure in Kirkwall, where Cullen was sure that the Maker had abandoned him. That his failure as Knight Captain had sundered him from grace, and that he was doomed to carry that failure all his life. But then the Inquisitor tumbled from the Fade and into his arms, and for the first tme it felt like he could breathe again. There were bad nights and horrible days, and when he finally tells her the truth the Commander is terrified that he is going to lose this last thing that truly gives meaning to his life. But the kiss sh presses to his forehead is like benediction, forgiveness and love all rolled into one, and for the first time in too long he can see a future in his mind’s eye– with her by his side.

Random thinking leading to sci-fi plot idea where in an fight between aliens and humans up in space a pilot of a ship gets boarded and then in the process of the fight gets separated from the rest of her crew. Upon checking over her ship in the aftermath she realizes that an alien is on board her vessel-yet it is not one of the ones fighting against the group of humans she belongs to or a known race she can identify. It is very much alien in form and figure (no glowy human nonsense or anything like that I MEAN ALIEN), they can’t even speak the same language, but the pilot realizes over time together that the alien has been trying to reach a planet to get back to its offspring as it had been abducted from its home planet.

Cue cute adventure of worried single alien dad and badass but caring pilot working together to get him back home as at the same time it gives information to help save the humans from the terrible fight against a galactic enemy and yes the two form a bond that as cliche as it is ends up with romantic human and alien snogging.
