Getting to Mars: What It’ll Take

Join us as we take a closer look at the next steps in our journey to the Red Planet:

The journey to Mars crosses three thresholds, each with increasing challenges as humans move farther from Earth. We’re managing these challenges by developing and demonstrating capabilities in incremental steps:

Earth Reliant

Earth Reliant exploration is focused on research aboard the International Space Station. From this world-class microgravity laboratory, we are testing technologies and advancing human health and performance research that will enable deep space, long duration missions.

On the space station, we are advancing human health and behavioral research for Mars-class missions. We are pushing the state-of-the-art life support systems, printing 3-D parts and analyzing material handling techniques.

Proving Ground

In the Proving Ground, we will learn to conduct complex operations in a deep space environment that allows crews to return to Earth in a matter of days. Primarily operating in cislunar space (the volume of space around the moon). We will advance and validate the capabilities required for humans to live and work at distances much farther away from our home planet…such as at Mars.

Earth Independent

Earth Independent activities build on what we learn on the space station and in deep space to enable human missions to the Mars vicinity, possibly to low-Mars orbit or one of the Martian moons, and eventually the Martian surface. Future Mars missions will represent a collaborative effort between us and our partners.

Did you know….that through our robotic missions, we have already been on and around Mars for 40 years! Taking nearly every opportunity to send orbiters, landers and rovers with increasingly complex experiments and sensing systems. These orbiters and rovers have returned vital data about the Martian environment, helping us understand what challenges we may face and resources we may encounter.

Through the Asteroid Redirect Mission (ARM), we will demonstrate an advanced solar electric propulsion capability that will be a critical component of our journey to Mars. ARM will also provide an unprecedented opportunity for us to validate new spacewalk and sample handling techniques as astronauts investigate several tons of an asteroid boulder.

Living and working in space require accepting risks – and the journey to Mars is worth the risks. A new and powerful space transportation system is key to the journey, but we will also need to learn new ways of operating in space.

We Need You!

In the future, Mars will need all kinds of explorers, farmers, surveyors, teachers…but most of all YOU! As we overcome the challenges associated with traveling to deep space, we will still need the next generation of explorers to join us on this journey. Come with us on the journey to Mars as we explore with robots and send humans there one day.

Join us as we go behind-the-scenes:

We’re offering a behind-the-scenes look Thursday, Aug. 18 at our journey to Mars. Join us for the following events:

Residence in Woody Creek, Colorado

Perched at the rivers edge, this Pampiano Residence by Studio B consists of an addition to the existing house as well as a detached garage with a dwelling unit above. The new architecture reinterprets the existing house and marries the project as ‘a whole’ through its use of materials, patterns and massing.

23 science facts we didn't know at the start of 2016

1. Gravitational waves are real. More than 100 years after Einstein first predicted them, researchers finally detected the elusive ripples in space time this year. We’ve now seen three gravitational wave events in total.

2. Sloths almost die every time they poop, and it looks agonising.

3. It’s possible to live for more than a year without a heart in your body.

4. It’s also possible to live a normal life without 90 percent of your brain.

5. There are strange, metallic sounds coming from the Mariana trench, the deepest point on Earth’s surface. Scientists currently think the noise is a new kind of baleen whale call.

6. A revolutionary new type of nuclear fusion machine being trialled in Germany really works, and could be the key to clean, unlimited energy.

7. There’s an Earth-like planet just 4.2 light-years away in the Alpha Centauri star system - and scientists are already planning a mission to visit it.

8. Earth has a second mini-moon orbiting it, known as a ‘quasi-satellite’. It’s called 2016 HO3.

9. There might be a ninth planet in our Solar System (no, Pluto doesn’t count).

10. The first written record demonstrating the laws of friction has been hiding inside Leonardo da Vinci’s “irrelevant scribbles” for the past 500 years.

11. Zika virus can be spread sexually, and it really does cause microcephaly in babies.

12. Crows have big ears, and they’re kinda terrifying.

13. The largest known prime number is 274,207,281– 1, which is a ridiculous 22 million digits in length. It’s 5 million digits longer than the second largest prime.

14. The North Pole is slowly moving towards London, due to the planet’s shifting water content.

15. Earth lost enough sea ice this year to cover the entire land mass of India.

16. Artificial intelligence can beat humans at Go.

17. Tardigrades are so indestructible because they have an in-built toolkit to protect their DNA from damage. These tiny creatures can survive being frozen for decades, can bounce back from total desiccation, and can even handle the harsh radiation of space.

18. There are two liquid states of water.

19. Pear-shaped atomic nuclei exist, and they make time travel seem pretty damn impossible.

20. Dinosaurs had glorious tail feathers, and they were floppy.

21. One third of the planet can no longer see the Milky Way from where they live.

22. There’s a giant, 1.5-billion-cubic-metre (54-billion-cubic-foot) field of precious helium gas in Tanzania.

23. The ‘impossible’ EM Drive is the propulsion system that just won’t quit. NASA says it really does seem to produce thrust - but they still have no idea how. We’ll save that mystery for 2017.

It’s Friday...Come Space Out with Us

It’s Friday…which seems like a great excuse to take a look at some awesome images from space.

First, let’s start with our home planet: Earth.

This view of the entire sunlit side of Earth was taken from one million miles away…yes, one MILLION! Our EPIC camera on the Deep Space Climate Observatory captured this image in July 2015 and the picture was generated by combining three separate images to create a photographic-quality image.

Next, let’s venture out 4,000 light-years from Earth.

This image, taken by the Hubble Space Telescope, is not only stunning…but shows the colorful “last hurrah” of a star like our sun. This star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star’s remaining core. Our sun will eventually burn out and shroud itself with stellar debris…but not for another 5 billion years.

The material expelled by the star glows with different colors depending on its composition, its density and how close it is to the hot central star. Blue samples helium; blue-green oxygen, and red nitrogen and hydrogen.

Want to see some rocks on Mars?

Here’s an image of the layered geologic past of Mars revealed in stunning detail. This color image was returned by our Curiosity Mars rover, which is currently “roving” around the Red Planet, exploring the “Murray Buttes” region.

In this region, Curiosity is investigating how and when the habitable ancient conditions known from the mission’s earlier findings evolved into conditions drier and less favorable for life.

Did you know there are people currently living and working in space?

Right now, three people from three different countries are living and working 250 miles above Earth on the International Space Station. While there, they are performing important experiments that will help us back here on Earth, and with future exploration to deep space.

This image, taken by NASA astronaut Kate Rubins shows the stunning moonrise over Earth from the perspective of the space station.

Lastly, let’s venture over to someplace REALLY hot…our sun.

The sun is the center of our solar system, and makes up 99.8% of the mass of the entire solar system…so it’s pretty huge. Since the sun is a star, it does not have a solid surface, but is a ball of gas held together by its own gravity. The temperature at the sun’s core is about 27 million degrees Fahrenheit (15 million degrees Celsius)…so HOT!

This awesome visualization appears to show the sun spinning, as if stuck on a pinwheel. It is actually the spacecraft, SDO, that did the spinning though. Engineers instructed our Solar Dynamics Observatory (SDO) to roll 360 degrees on one axis, during this seven-hour maneuver, the spacecraft took an image every 12 seconds.

This maneuver happens twice a year to help SDO’s imager instrument to take precise measurements of the solar limb (the outer edge of the sun as seen by SDO).

Thanks for spacing out with us…you may now resume your Friday.

I want to see an adventure story set in medieval Bologna

Or Assassin's Creed

The city of Bologna in the 12th-13th century - the closest we can get to a medieval skyscraper city; because nobles used to build high towers as a symbol of power and also for offensive/defensive purposes, at one point there were around 100 such towers.

IS SCIENCE EATING ITS YOUNG?

Background.  Scientists and policy makers around the world increasingly worry about the plight of young researchers in academia, and for good reason. Competition for tenure-track positions has surged, and some early career researchers face tough odds in the quest for funding.  This week Nature pleads the case for the young in a special issue.

Design challenge.  How do we visually convey the idea that science is eating its young? We felt it was important to represent a system that has gone wrong, with various consequences, in an engaging way. The metaphor of a video came to mind, as young scientists find themselves trapped in framework, playing along.

We gave this brief to Megapont, an artist that specializes in isometric pixel art, and he created a fantastic scene for the cover. The retro gaming vibe gives a sense of an aging system that needs an overhaul. The detail in the artwork rewards the observant reader, with hidden treasures and references to iconic games and other worlds. And check out the tiny rat fleeing the scene - only a few pixels!

Have your say. Perhaps you are a young scientist who identifies with a cover character? Maybe the one slouched in dispair on the floor, or the one cutting out in bunny slippers? We’d like to hear your story – here’s a tumblr just for you: researchrealities.tumblr.com
