"Exploration is in our nature. We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars." - Carl Sagan

Wanderers is a vision of humanity’s expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available. Watch the breathtaking short film on Vimeo.

Well, at long last, NASA’s New Horizons probe woke up. Yesterday it did its final wake up on its way to Pluto.

By early July we’ll have the first full color, close up images of Pluto and other Kuiper Belt objects. Everything we know about the outer solar system will be revolutionized.

What is hiding out in the far solar system? Are there even more dwarf planets than we know out there? Could there be a “Planet X”?

If you want an idea of how good the camera is, look at the photograph it took of Jupiter and Io. It’s the highest resolution color portrait ever made of Jupiter. It includes some near infrared light which is why it seems a little redder than usual. You can also see a blue plume emerging from Io’s north pole, this is a volcanic eruption.

It’ll be a real exciting Summer

Rosette Nebula NGC 2237 in Monoceros
The Rosette Nebula (NGC 2237, Caldwell 49) in Monoceros is a showpiece astrophotography object for telescopes of any size, resembling a large open flower with an open cluster of stars (NGC 2244, Caldwell 50) in the darker center. It lies about 5,200 light years away and is 130 light years across. The stellar winds from these young, hot stars are clearing the center portion of the nebula, but their ultraviolet radiation is so strong that it still causes the rest of the nebula to glow. Initially, 36 stars were identified to make up the cluster, but Chandra space telescope X-Ray data increase that number to about 160 stars and showed that this is a place of new star formation from all the dust and gas. Note the huge, dark spires of dust projecting toward the center of the Rosette.

I want to reveal one of the greatest mysteries in science to you:

Look at this gif, notice any patterns in the orbits? I’m talking about the speeds. The planets orbiting around the Sun get slower the farther out they go.

Why is this? Kepler’s Third Law of Planetary Motion.

The stars in the Milky Way orbit around the Galactic Center just as our planets do around the Sun. We find that the farther you get from the center of the galaxy… there’s approximately no change in orbital velocity.

Just like that, one of our most well-established tools in astronomy (Kepler’s Third Law) becomes ineffective for some reason.

It’s become apparent to astronomers that when something orbits around a center of mass, it’s orbital speed has a relationship with the distance from the center of mass.

Right now we don’t think most of the mass of the Milky Way is focused in the galactic center, but hidden in darkness surrounding the galaxy on all sides.

What we know is that it’s impossible to see and so far has eluded detection: we’ve started calling this mysterious mass dark matter.

The Journey to Mars Begins Tomorrow

  • NASA is preparing for the first test flight of the Orion crew vehicle set for an unmanned launch on Dec. 4 at 7:05 a.m. EST from Cape Canaveral, Florida.

  • The Orion spacecraft is designed to eventually take astronauts beyond low-Earth orbit to destinations never explored by humans. It will serve as the exploration vehicle that will carry the crew to distant planetary bodies, provide emergency abort capability, sustain the crew during space travel, and provide safe reentry from deep space.

  • This mission is the first of three trial runs that the Orion mission must overcome before NASA deems it safe enough for human space travel. 

  • The next test flights in 2018 and 2021 will use NASA’s Space Launch System rocket (SLS), which is currently in development. When it’s finished, SLS will be the most powerful rocket ever built, boasting even more thrust than the Saturn V booster that blasted astronauts toward the moon in the Apollo era.
     
  • The spacecraft will launch atop a Delta IV Heavy, a rocket built and operated by United Launch Alliance. While this launch vehicle will allow Orion to reach an altitude high enough to meet the objectives for this test, a much larger, human-rated rocket will be needed for the vast distances of future exploration missions.

  • Exploration Flight Test-1, will mark the farthest distance traveled by a human spaceflight vehicle since 1972 made by Apollo 17.

  • During its grueling four-and-half-hour test mission, NASA’s Orion space capsule must shoot 3,600 miles away from Earth (15 times higher than the International Space Station!), orbit the planet twice, and brave a thick belt of cosmic radiation. 

  • Upon re-entry it must deploy 11 parachutes to slow down from 20,000 miles per hour to 20 mph, while withstanding 4,000-degree Fahrenheit temperatures before plunging into the Pacific Ocean. 

  • Check out these incredible photos from the development and testing of the spacecraft.

  • Countdown, launch and mission coverage will begin at 4:30 a.m. on NASA TV which is available on air and streaming at nasa.gov/nasatv
