This weekend marks the 400th anniversary of Shakespeare’s death, and we’re highlighting the moons of Uranus; some of which are named after characters from his works.
While most of the moons orbiting other planets take their names from Greek mythology, Uranus’ moons are unique in bing named for Shakespearean characters, along with a couple of them being named for characters from the works of Alexander Pope.
Using the Hubble Space Telescope and improved ground-based telescopes, astronomers have discovered a total of 27 known moons around Uranus.
Shakespearean work: The Tempest
Miranda, the innermost and smallest of the five major satellites, has a surface unlike any other moon that’s been seen. It has a giant fault canyon as much as 12 times as deep as the Grand Canyon, terraced layers and surfaces that appear very old, and others that look much younger.
Shakespearean work: The Tempest
Ariel has the brightest and possibly the youngest surface among all the moons of Uranus. It has a few large craters and many small ones, indicating that fairly recent low-impact collisions wiped out the large craters that would have been left by much earlier, bigger strikes. Intersecting valleys pitted with craters scars its surface.
Shakespearean work: A Midsummer Night’s Dream
Oberon, the outermost of the five major moons, is old, heavily cratered and shows little signs of internal activity. Unidentified dark material appears on the floors of many of its craters.
Shakespearean works: Cordelia - King Lear; Ophelia - Hamlet
Cordelia and Ophelia are shepherd moons that keep Uranus’ thin, outermost “epsilon” ring well defined.
Between them and miranda is a swarm of eight small satellites unlike any other system of planetary moons. This region is so crowded that astronomers don’t yet understand how the little moons have managed to avoid crashing into each other. They may be shepherds for the planet’s 10 narrow rings, and scientists think there must be still more moons, interior to any known, to confine the edges of the inner rings.

If you couldn’t tell already, NASA is having a great year. From Pluto to food grown in space, even in the face of budget cuts, the nation’s space agency had some stellar highlights. Most mysteriously of all, a spacecraft found two eerily bright lights on a distant dwarf planet.

Astronaut Scott Kelly is currently spending a year in space. Most expeditions to the space station last four to six months. By doubling the length of this mission, researchers hope to better understand how the human body reacts and adapts to long-duration spaceflight. During this one-year mission, Kelly is also participating in the Twins Study. While Kelly is in space, his identical twin brother, retired NASA Astronaut Mark Kelly, will participate in a number of comparative genetic studies.
Here are a few things that happen when astronauts go to the space station:

Have you ever packed for a long trip with a friend and ran out of space in your suitcase? Maybe your friend was nice and let your spare items hitchhike a ride in their bag? The following science experiments are doing something similar on our Space Launch System rocket.
Our Space Launch System (SLS) will be the most powerful rocket we’ve ever built and will enable astronauts in the Orion spacecraft to travel deeper into the solar system. This advanced launch vehicle will launch astronauts to an asteroid and eventually to Mars, while opening new possibilities for other payloads including robotic scientific missions to places like Mars, Saturn and Jupiter.
The primary goal of SLS and the Orion spacecraft is to launch future crewed, deep space missions. That said, an added bonus of this powerful rocket is the extra science it can carry. On it’s first mission (known as Exploration Mission-1, EM-1) SLS will carry 13 CubeSats (small satellites, each the size of a large shoebox) on its first flight as secondary payloads. These small satellites will perform various in-space experiments. In a way, these 13 CubeSats are ‘space hitchhikers’, catching a ride to deep space where they can gather data valuable to future exploration missions.
How were these 13 experiments selected? Great question. They were selected through a series of announcements of flight opportunities, a public contest and negations with our international partners.
These secondary payloads have a vast array of functions, from taking pictures of asteroids, to using yeast to detect impacts of deep-space radiation. Each month we will highlight one of these experiments on Tumblr and talk about all the exciting science they will do. Just to give you an idea of what these shoebox-sized satellites will do, we’ll give you a preview:
1. NEA Scout
NEA Scout, stands for: Near-Earth Asteroid Scout. This CubeSat will investigate an asteroid, taking pictures and observe its position in space.
2. BioSentinel
BioSentinel will be the first time living organisms have traveled to deep space in more than 40 years. It will use yeast to detect, measure and compare the impact of deep-space radiation on living organisms over long durations in deep space.
3. Lunar Flashlight
This experiment will look for ice deposits and identify locations where resources may be extracted from the lunar surface. It will demonstrate the capability to scout for useful materials and resources from lunar orbit.
4. Skyfire
Lockheed Martin’s Skyfire will perform a lunar flyby, collecting data to address both Moon and Mars Strategic Knowledge Gaps, or gaps in information required to reduce risk, increase effectiveness and improve the design of robotic and human space exploration missions, for surface characterization, remote sensing and site selection.
5. Lunar IceCube
Morehead State University’s Lunar IceCube will look for water in ice, liquid and vapor forms from a very low orbit of only 62 miles above the surface of the moon. The ability to search for useful resources can potentially help astronauts manufacture fuel and necessities to sustain a crew.
6. CuSP
The CubeSat mission to study Solar Particles, or CuSP, will be the first protype of an interplanetary CubeSat space weather station. It will observe space weather events hours before they reach Earth.
7. Luna-H-Map
Lunar Polar Hydrogen Mapper (LunaH) will enter a polar orbit around the moon with a low altitude. From there, it will produce maps of near-surface hydrogen.
8, 9, 10. Three Tournament Payloads
Three of the payloads riding along on this journey will be the winners of the Ground Tournaments portion of our CubeQuest Challenge. This challenge is designed to foster innovation in small spacecraft propulsion and communications techniques. Learn more about this challenge HERE.
11, 12, 13. International Partners
The remaining three payloads are reserved for international partners, and will be announced at a later time.

i get a lot of questions about how to contribute to the campaign without being able to vote, and right now is a pivotal time for us to be supporting Bernie Sanders in every way we can.
if you’re too young, not registered, not eligible, not a US citizen or living in the US, or already voted and still want to help, you can still contribute! right now closing the delegate gap is more important than the individual state primaries, and to make any difference on that front we need more volunteers.
the best thing to do right now, even if you're voting/have voted, is to volunteer for the campaign and work with your local Bernie supporters to get more delegates. below are links to websites where you can find contact information for the remaining states. contact someone on the local campaign (in your area, or in any state you think needs support!) and ask them how you can best help their efforts. I’ve been doing phone banking and collecting signatures for delegates in rhode island, as well as attending events and hanging out fliers, and trust me when i say any little bit helps.
remember, Obama lost more states to Hillary at this point in the primary than Bernie has. he had the delegate support, and there’s still time to catch up to Hillary’s numbers if we all pitch in.
here is a list of all the states left in the primary, and the website for their local grassroots movement:

Have you ever wondered if you have what it takes to become a NASA Astronaut? The term “astronaut” derives from the Greek word meaning “space sailor,” and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond.
We’re looking for a new class of astronauts to join the NASA team, and here are a few things to know.
MYTH: All astronauts have piloting experience.
FACT: You don’t need to be a pilot to be an astronaut. Flying experience is not a requirement, but could be beneficial to have.
MYTH: All astronauts have perfect vision.
FACT: It’s okay if you don’t have 20/20 vision. As of September 2007, corrective surgical procedures of the eye (PRK and LASIK), are now allowed, providing at least 1 year has passed since the date of the procedure with no permanent adverse after effects.
MYTH: All astronauts have advanced degrees like, a PhD.
FACT: While a Bachelor’s degree from an accredited university is necessary, an advanced degree is not required to become an astronaut.
MYTH: Astronauts are required to have military experience in order to be selected.
FACT: Military experience is not required to become an astronaut.
MYTH: You have to be a certain age in order to be an astronaut.
FACT: There are no age restrictions. Astronaut candidates selected in the past have ranged between the ages of 26 and 46, with the average age being 34.

After 65 years of Charlie Brown, Snoopy and the whole Peanuts gang, what keeps us coming back again and again?
“The ‘Peanuts’ story is arguably one of the longest-running works of contemporary American literature of our time,” author and editor Chip Kidd told us today as we explored the new “Peanuts” movie and his new Schulz retrospective, “Only What’s Necessary.”
