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:

Journey to Mars Televised Event at 9:30 a.m. EDT Join in as we host a conversation about the numerous efforts enabling exploration of the Red Planet. Use #askNASA to ask your questions! Tune in HERE.

Facebook Live at 1:30 p.m. EDT Join in as we showcase the work and exhibits at our Michoud Assembly Facility. Participate HERE.

Hot Fire Test of an RS-25 Engine at 6 p.m. EDT The 7.5-minute test is part of a series of tests designed to put the upgraded former space shuttle engines through the rigorous temperature and pressure conditions they will experience during a launch. Watch HERE.

10 “Out of This World" Facts About the James Webb Space Telescope

Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!

Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.

Here are 10 awesome facts about this next generation space telescope:

1. The James Webb Space Telescope is the world’s largest and next premier space observatory. It will extend the discoveries of the Hubble Space telescope and observe the birthplaces of stars, galaxies, planets and life over billions of years.

2. It is named after James Webb, NASA’s second administrator and champion of our science.

3. At 3 stories high and the size of a tennis court, it will be 100 times more powerful than Hubble!

4. It is so big that it has to fold origami-style to fit in the rocket, which is only 5.4 meters wide…And then it will unfurl, segment by segment, once in space.

5. The telescope will observe infrared light with unprecedented sensitivity. It will see the first galaxies born after the Big Bang over 13.5 billion years ago.

6. Webb’s infrared cameras are so sensitive they must be shielded from light from the sun, Earth, and moon. The 5-layer sunshield is like having sunblock of SPF 1 million.

7. Webb will orbit the sun 1 million miles from Earth, where the telescope will operate at temperatures below -390 F (-235 C).

8. Webb’s mirrors are coated with a super thin layer of gold only about 1000 atoms thick to optimize their reflectivity in the infrared.

9. Webb will launch from French Guiana in 2018. It is launched near the equator because the faster spin of Earth there gives the rocket an extra push.

10. Webb is an international mission, with contributions from the European Space Agency and Canadian Space Agency. Once operational, scientists from all over the world will be able to use Webb to explore our solar system, planets outside our solar system, stars and galaxies.

RoboAction

Painting series by Dragan Ilić features abstracted mark-making using an industrial robot, sometimes carrying and guiding the artist himself:

The artist constantly transposes into the third dimension his decade’s long-running conceptual practice based on the usage of pencils as the basic draftsman’s tool, starting primarily with the media of performance art, installation and sculpture in extended field. Gradually, over the years, his expressive and mechanical compositions have become even more advanced with the development of modules, diverse in shape and sizes, devices designed for the task of mounting and holding his drawing tools, which has led ultimately to the construction of an appropriate drawing machine. Construed for non-artistic purposes, these robots have been reshaped into special draftsmanship implements with which the author is capable of processing his ideas at far greater speed and with considerably greater precision. The metamorphosis of the artistic work is positioned at a point where human and machine activity intersects, resulting in an interaction that is essentially based on the need to transcend the limitations of the human body.

India just launched 20 satellites in 26 minutes and made history

Congrats!

The Indian Space Research Organisation (ISRO) just sent 20 satellites into orbit with one launch, marking the largest satellite launch in the space agency’s history.

Their previous record was 10 satellites delivered with one mission, and this latest accomplishment takes them a lot closer to the delivery rates of NASA and the Russian Federal Space Agency, solidifying India’s place in the global space market.

Out of the 20 satellites, 17 were commercial, so used by companies to help us do things like get better TV signals or weather forecasts. The main cargo, though, was the ISRO’s 725.5-kilogram (1,599-pound) Cartosat-2 - a satellite used for earth observation much like NASA’s Landsat program.

New Evidence Found which Matches Legendary Founding of the First Dynasty of China

A archaeological team from Beijing University have found new evidence that surprisingly fits the ancient Chinese histories’ accounts of the founding of the Xia Dynasty. Previously, historians had dismissed all accounts of the first, second, and third dynasties as fabrications. They were written to glorify the dynasties which came later, not to document what had really happened. But archaeological findings over the last century provided evidence that the second and third dynasties had really existed. The Shang Dynasty you likely heard about in schools. Yup, we had once thought it was a myth. Now science and archaeology may be confirming the earliest dynasty written about existed as well. Read more

Is SQL useful for astrophysics or chemistry in any way?

Well the Q and the L aren’t but as you can see astrophysics and chemistry both use the letter S at least once per word. Hope that helped you
