Washington, D.C. – NASA is hard at work building the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems needed to send astronauts into deep space. The agency is developing the core capabilities needed to enable the journey to Mars.
Orion’s first flight atop the SLS will not have humans aboard, but it paves the way for future missions with astronauts. Ultimately, it will help NASA prepare for missions to the Red Planet. During this flight, currently designated Exploration Mission-1 (EM-1), the spacecraft will travel thousands of miles beyond the moon over the course of about a three-week mission.

Washington, D.C. – Winter is approaching. The early, wakeful sunbeams of summer are a fading memory as October mornings grow dark and cold. Frankly, waking up isn’t as easy as it used to be…..
Except this week.
In the days ahead, if you find yourself yawning over your morning coffee before sunrise, longing for repose, just take a look out the window. Three bright planets are converging in the eastern sky–and the view is an eye opener.

Washington, D.C. – Imagine a world with extreme temperatures that can wreak havoc on unprotected spacecraft and habitat components; a world where water is so scarce that plants are outfitted with sensors so farmers can avoid overwatering them; a world where precious water supplies are found in underground oases by satellites in orbit; a world where systems filter, recycle and purify air for the survival of inhabitants huddled in shelters.
Although images of human habitation on Mars may have filled your mind, the world just described is actually Earth, and the technologies cited are spinoffs, or technologies developed by the American space program that have gone on to benefit the public.

Washington, D.C. – NASA is leading our nation and the world on a journey to Mars, and Thursday the agency released a detailed outline of that plan in its report, “NASA’s Journey to Mars: Pioneering Next Steps in Space Exploration.”
“NASA is closer to sending American astronauts to Mars than at any point in our history,” said NASA Administrator Charles Bolden. “We are publishing additional details about our journey to Mars plan and how we are aligning all of our work in support of this goal. In the coming weeks, I look forward to continuing to discuss the details of our plan with members of Congress, as well as our commercial and our international and partners, many of whom will be attending the International Astronautical Congress next week.”

Pasadena, CA – When fictional astronaut Mark Watney becomes stranded alone on the Red Planet in the novel and film “The Martian,” people and technology from NASA’s Jet Propulsion Laboratory in Pasadena, California, play important roles in his castaway adventure.
Acclaimed for its attention to scientific and technical detail, “The Martian” is steeped in decades of real-life Mars exploration that JPL has led for NASA.

Pasadena, CA – New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars.
Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time.
They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times.

Greenbelt, MD – For years, science fiction writers from Edgar Rice Burroughs to C. S. Lewis have imagined what it would be like for humans to walk on Mars. As mankind comes closer to taking its first steps on the Red Planet, authors’ depictions of the experience have become more realistic.
Andy Weir’s “The Martian” begins with a massive dust storm that strands fictional astronaut Mark Watney on Mars. In the scene, powerful wind rips an antenna out of a piece of equipment and destroys parts of the astronauts’ camp.
Mars is infamous for intense dust storms, which sometimes kick up enough dust to be seen by telescopes on Earth.

Pasadena, CA – Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.
A new analysis of the largest known deposit of carbonate minerals on Mars suggests that the original Martian atmosphere may have already lost most of its carbon dioxide by the era of valley network formation.
“The biggest carbonate deposit on Mars has, at most, twice as much carbon in it as the current Mars atmosphere,” said Bethany Ehlmann of the California Institute of Technology and NASA Jet Propulsion Laboratory, both in Pasadena.

Pasadena, CA – Ten years after launch, NASA’s Mars Reconnaissance Orbiter (MRO) has revealed the Red Planet’s diversity and activity, returning more data about Mars every week than all six other missions currently active there. And its work is far from over.
The workhorse orbiter now plays a key role in NASA’s Journey to Mars planning. Images from the orbiter, revealing details as small as a desk, aid the analysis of potential landing sites for the 2016 InSight lander and Mars 2020 rover. Data from the orbiter will also be used as part of NASA’s newly announced process to examine and select candidate sites where humans will first explore the Martian surface in the 2030s.

Pasadena, CA – On the three-year anniversary of the Mars landing of NASA’s Curiosity rover, NASA is unveiling two new online tools that open the mysterious terrain of the Red Planet to a new generation of explorers, inviting the public to help with its journey to Mars.
Mars Trek is a free, Web-based application that provides high-quality, detailed visualizations of the planet using real data from 50 years of NASA exploration and allowing astronomers, citizen scientists and students to study the Red Planet’s features.
