Mars. In true colour.

Just so you know, a lot of images of Mars which you’ll see have been manipulated. A lot of them have boosted contrast and saturation. So if you’ve ever wondered – images like this one are what Mars actually looks like.

Some magical sisters from my absolute favorite book series of all time: the Young Wizards series! It’s really under-appreciated tbh and I, 10/10, recommend it!! Anyway, even if you haven’t read it, you still can appreciate the art I guess  ◕ ‿ ◕

Coldest Star Found—No Hotter Than Fresh Coffee

According to a new study, a star discovered 75 light-years away is no warmer than a freshly brewed cup of coffee.

Dubbed CFBDSIR 1458 10b, the star is what’s called a brown dwarf. These oddball objects are often called failed stars, because they have starlike heat and chemical properties but don’t have enough mass for the crush of gravity to ignite nuclear fusion at their cores.

With surface temperatures hovering around 206 degrees F (97 degrees C), the newfound star is the coldest brown dwarf seen to date.

At least once Nita makes it to college she won’t have to keep asking her dad or counselor to cover for her when she has to miss school. If one of my students emailed me saying they were going to miss class because they had to stop the universe from tearing itself apart I’d be like ‘cheers I’ll drink to that bro’

NASA's Next Giant Leap

Technology drives exploration and we're building on the Apollo program's accomplishments to test and fly transformative, cutting edge technologies today for tomorrow's missions. As we develop and test the new tools of 21st century spaceflight on the human path to Mars, we once again will change the course of history.

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
