Sit Back And Space Out

Hello! I am an avid lover of the cosmos and all things too grand for our minds to grasp. I was wondering, honestly, how do you cope with the pressure of your jobs, or say the scale of what is on your shoulders? It's quite an impressive thing you do, and it just gets me curious as to how you deal with the expectations that come with this type of job? Like, when you go home at night and eat your dinner, go to bed, do you have to practice mindfulness? Thanks for answering these! Love you guys!!!

New Research Heading to Earth’s Orbiting Laboratory

It’s a bird! It’s a plane! It’s a…dragon? A SpaceX Dragon spacecraft is set to launch into orbit atop the Falcon 9 rocket toward the International Space Station for its 12th commercial resupply (CRS-12) mission August 14 from our Kennedy Space Center in Florida.

It won’t breathe fire, but it will carry science that studies cosmic rays, protein crystal growth, bioengineered lung tissue.

Here are some highlights of research that will be delivered:

I scream, you scream, we all scream for ISS-CREAM! 

Cosmic Rays, Energetics and Mass, that is! Cosmic rays reach Earth from far outside the solar system with energies well beyond what man-made accelerators can achieve. The Cosmic Ray Energetics and Mass (ISS-CREAM) instrument measures the charges of cosmic rays ranging from hydrogen to iron nuclei. Cosmic rays are pieces of atoms that move through space at nearly the speed of light

The data collected from the instrument will help address fundamental science questions such as:

Do supernovae supply the bulk of cosmic rays?

What is the history of cosmic rays in the galaxy?

Can the energy spectra of cosmic rays result from a single mechanism?

ISS-CREAM’s three-year mission will help the scientific community to build a stronger understanding of the fundamental structure of the universe.

Space-grown crystals aid in understanding of Parkinson’s disease

The microgravity environment of the space station allows protein crystals to grow larger and in more perfect shapes than earth-grown crystals, allowing them to be better analyzed on Earth. 

Developed by the Michael J. Fox Foundation, Anatrace and Com-Pac International, the Crystallization of Leucine-rich repeat kinase 2 (LRRK2) under Microgravity Conditions (CASIS PCG 7) investigation will utilize the orbiting laboratory’s microgravity environment to grow larger versions of this important protein, implicated in Parkinson’s disease.

Defining the exact shape and morphology of LRRK2 would help scientists to better understand the pathology of Parkinson’s and could aid in the development of therapies against this target.

Mice Help Us Keep an Eye on Long-term Health Impacts of Spaceflight

Our eyes have a whole network of blood vessels, like the ones in the image below, in the retina—the back part of the eye that transforms light into information for your brain. We are sending mice to the space station (RR-9) to study how the fluids that move through these vessels shift their flow in microgravity, which can lead to impaired vision in astronauts.

By looking at how spaceflight affects not only the eyes, but other parts of the body such as joints, like hips and knees, in mice over a short period of time, we can develop countermeasures to protect astronauts over longer periods of space exploration, and help humans with visual impairments or arthritis on Earth.

Telescope-hosting nanosatellite tests new concept

The Kestrel Eye (NanoRacks-KE IIM) investigation is a microsatellite carrying an optical imaging system payload, including an off-the-shelf telescope. This investigation validates the concept of using microsatellites in low-Earth orbit to support critical operations, such as providing lower-cost Earth imagery in time-sensitive situations, such as tracking severe weather and detecting natural disasters.

Sponsored by the ISS National Laboratory, the overall mission goal for this investigation is to demonstrate that small satellites are viable platforms for providing critical path support to operations and hosting advanced payloads.

Growth of lung tissue in space could provide information about diseases

The Effect of Microgravity on Stem Cell Mediated Recellularization (Lung Tissue) uses the microgravity environment of space to test strategies for growing new lung tissue. The cells are grown in a specialized framework that supplies them with critical growth factors so that scientists can observe how gravity affects growth and specialization as cells become new lung tissue.

The goal of this investigation is to produce bioengineered human lung tissue that can be used as a predictive model of human responses allowing for the study of lung development, lung physiology or disease pathology.

These crazy-cool investigations and others launching aboard the next SpaceX #Dragon cargo spacecraft on August 14. They will join many other investigations currently happening aboard the space station. Follow @ISS_Research on Twitter for more information about the science happening on 250 miles above Earth on the space station.  

Watch the launch live HERE starting at 12:20 p.m. EDT on Monday, Aug. 14!

What are the moments when you think to yourself "yes. THIS is why I love my job"..? ✨

What’s Up for June 2016?

What's Up for June? Saturn at its best! Plus, good views of Mars, Jupiter and Jupiter's moons continue from dusk to dawn.

You don't have to stay up late to see Jupiter, Mars and Saturn this month, because they're all visible soon after sunset. Jupiter is the brightest of the three, visible in the western sky all evening. 

The four Galilean moons are easily visible in binoculars or telescopes. If you think you're seeing 5 moons on June 10th, you're not. One of them is a distant star in the constellation Leo.

For telescope viewers, the time near Mars' closest approach to Earth, May 30th this year, is the best time to try to see the two moons of Mars: Phobos and Deimos. It takes patience, very steady skies and good charts! Mars is still large and bright in early June, but it fades as speedy Earth, in its shorter orbit around the sun, passes it.

Saturn has been close to Mars recently. This month Saturn reaches opposition, when Saturn, Earth and the sun are in a straight line with Earth in the middle, providing the best and closest views of the ringed beauty and several of its moons. You'll be able to make out cloud bands on Saturn, in delicate shades of cream and butterscotch. They're fainter than the bands of Jupiter. Through a telescope you'll see Saturn's rings tilted about as wide as they get: 26 degrees.

You'll also have a ring-side view of the Cassini division, discovered by Giovanni Domenico Cassini, namesake of our Cassini spacecraft, orbiting Saturn since 2004 and continuing through September 2017. When you look at Saturn through a telescope, you can't help but see several of its 4 brightest moons, and maybe more. If you just see one, that's Titan, 50% larger than our own moon. A telescope can also reveal more moons, like Saturn's two-colored moon Iapetus. It takes 3 months to orbit Saturn, and it's fairly easy to see.

There's a bright comet visible this month, Comet PanSTARRS. It's best seen from the southern hemisphere, but it's also visible from the U.S. low in the morning sky. Comet PanSTARRS can be seen through a telescope near the beautiful Helix Nebula on June 4, but it is visible all month.

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.

Throwback Thursday: Apollo 11 Moon Landing Questions Answered

The Apollo 11 Moon landing was a feat for the ages. With the help of the NASA History Office, we’ve identified some of the most frequently asked questions surrounding the first time humans walked on the surface of another world. Click here to check out our post from last week. 

Is it true that the Apollo guidance computer had less computing power than a smartphone?

Believe it or not, yes! The Apollo guidance computer not only had less computing power than a smartphone, it had less computing power than the calculator you use in your algebra class. The computer, designed by MIT, had a fixed memory of 36 kilobytes and an erasable memory of 2 kilobytes. That’s fairly advanced for the time! 

Why did Buzz Aldrin take a picture of his bootprint?

A substantial portion of the Apollo 11 crew’s checklist was taking photographs. Taking closeup shots of the "very fine” moon dust was a critical component of mission objectives and helped scientists better understand the surface makeup of the Moon. 

Armstrong and Aldrin wore lunar overboots over their main spacesuit boots to protect them from ultraviolet radiation and hazardous rocks. To make room for the nearly 50 pounds (22 kilograms) of lunar samples, the crew left all their pairs of boots on the Moon. But don’t worry; they wouldn’t get charged an overweight baggage fee anyway. 

What were the first words spoken from the surface of the Moon?

That’s somewhat subject to interpretation. Once the Lunar Module’s surface sensor touched the surface, Buzz Aldrin called out "Contact Light” to Mission Control. After the engine shut down, he said “ACA out of detent,” simply meaning that the Eagle’s Attitude Control Assembly, or control stick, was moved from its center position. 

But the first words heard by the entire world after Apollo 11 touched down were delivered by Neil Armstrong: "Houston, Tranquility Base here. The Eagle has landed.” More than six hours later, Armstrong stepped off the Eagle’s footpad and delivered the most famous words ever spoken from the surface of another world: "That's one small step for [a] man, one giant leap for mankind."  And although we have a hard time hearing it in the recording, Armstrong clarified in a post-flight interview that he actually said, “That’s one small step for a man...”

What will the first woman and the next man to go to the Moon say when they first step on its surface?

We can’t say for sure what our next moonwalkers will decide to say, but perhaps the better question is: What would be your first words if you were to land on the Moon? There’s no doubt that the astronauts of the Artemis Generation will inspire a new crop of explorers the way Apollo Generation astronauts did 50 years ago.  Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.

Hostile and Closed Environments, Hazards at Close Quarters

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

A spacecraft is not only a home, it’s also a machine. NASA understands that the ecosystem inside a vehicle plays a big role in everyday astronaut life.

Important habitability factors include temperature, pressure, lighting, noise, and quantity of space. It’s essential that astronauts are getting the requisite food, sleep and exercise needed to stay healthy and happy. The space environment introduces challenges not faced on Earth.

Technology, as often is the case with out-of-this-world exploration, comes to the rescue! Technology plays a big role in creating a habitable home in a harsh environment and monitoring some of the environmental conditions.

Astronauts are also asked to provide feedback about their living environment, including physical impressions and sensations so that the evolution of spacecraft can continue addressing the needs of humans in space.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including hostile and closed environments, like the closed environment of the vehicle itself. To learn more, and find out what NASA’s Human Research Program is doing to protect humans in space, check out the "Hazards of Human Spaceflight" website. Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of hostile and closed environments with Brian Crucian, NASA immunologist at the Johnson Space Center.
