Charles Bolden resigned as NASA Administrator on Jan. 20, 2017. This blog is being kept online for historical purposes, but it will no longer be updated.
I’m delighted to share that NASA has been named the “Best Place to Work” among large agencies in the federal government for an impressive fifth year in a row. The credit for this accolade goes entirely to the NASA workforce, and I am honored to work with every one of them and serve as NASA Administrator.
The annual results of this survey of federal workers is published by the Partnership for Public Service. It ranks nearly 400 federal organizations by overall employee satisfaction and commitment, and also evaluates key workplace focus areas, such as innovation, training and development, leadership and diversity.
This year, participation in the survey increased across the board across all of our NASA centers, which means that more of our workforce made their voice heard about what they love about working at NASA – as well as what they’d like to see improved.
The NASA workforce’s passion and dedication to our missions and each other is also evident in this year’s results, because every single question increased in percent favorability. This commitment to continuous innovation – whether applied to our missions or to improving our work environment – is what makes NASA so special, and is the fuel for our journey to Mars and all of our cutting edge missions in air and space.
I want to thank the Partnership for their continued recognition of the importance of public service and their efforts to call positive attention to federal workers and to careers in the federal government. I also want to give a special thanks to our mid-level managers and supervisors — the frontline resource and role models to our thousands of employees. They motivate all of us to go above and beyond as we reach for new heights in exploring space, learning more about our planet and enhancing human capabilities.
As I reflect on my time as NASA Administrator, I feel incredibly proud to call everyone in the NASA workforce my colleagues. I’ve always said that they are creating the future, and no matter their area of expertise, their commitment to the agency’s missions in every area has made all of our accomplishments possible, and makes everything we dream for achievable.
There are some moments that will stay with you your entire life. I’d be willing to bet that most of the people with whom I spent this morning at NASA’s Goddard Space Flight Center would put the experience in that category. You see, we were able to see with our own eyes the amazing progress that’s being made on the James Webb Space Telescope, which will soon be humanity’s eye into the secrets and mysteries of the universe.
Just recently, we completed the first important optical measurement of JWST’s segmented mirror, called a Center of Curvature test, to measure the shape of Webb’s mirror before it goes into the testing chambers. We also just finished the sunshield layers, which will protect Webb’s sensitive instruments from the sun once it’s in space.
As we reach for new heights for the benefit of all humankind, NASA has always sought to unravel the mysteries of our universe; to find out where we come from, where we are going, and whether we are alone in the universe.
We are building the James Webb Space Telescope to answer these age-old questions and to bring us to new heights in discovery, understanding and human progress. Webb will allow us to explore ever further into the cosmos, seeing things far beyond the capabilities of the Hubble Space Telescope. It will see the universe light up with the first galaxies to form after the Big Bang and study the formation of star systems capable of supporting life on planets like Earth.
Webb will help us search for signs of life and learn more about the habitability of planets discovered by our fleet of planet hunters and world explorers, including Kepler and the upcoming Transiting Exoplanet Survey Satellite. Webb will also help us understand the evolution and composition of our own Solar System, from the icy moons around Jupiter and Saturn, to known comets and asteroids. It will help us on our Journey to Mars by helping us understand more about the Red Planet, including Martian climate patterns.
Upon completion, Webb will be the largest and most complex space observatory that anyone on planet Earth has ever built. At about the size of a tennis court, it will be folded origami-style to fit in the Ariane 5 rocket (about 5 meters wide), and will unfurl in cryogenic temperatures where materials behave in ways that defy everything we’re used to on Earth. It will be launched from French Guiana in 2018.
Even before Webb allows us to rewrite textbooks and answer questions we have not yet thought to ask, it is already shattering the boundaries of space technology. What’s more, it is changing the field of materials science.
Webb is the work of our nation, with more than 120 American universities, organizations, and companies in 27 states coast to coast (including Hawaii) bringing together some of the brightest minds in our country to make Webb a reality. Webb’s findings will be incorporated into science, technology, engineering and mathematics (STEM) education worldwide, inspiring future generations of explorers, scientists and engineers. It will capture the imagination and dreams of millions who dare to look to the sky and wonder.
At the same time, it is an international collaboration — a partnership among NASA, ESA (the European Space Agency) and the Canadian Space Agency (CSA). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is managing the development effort. Northrop Grumman is the main industry partner and the Space Telescope Science Institute will operate Webb after launch.
Dr. Martin Luther King, Jr. once said “In a real sense all life is inter-related. All [people] are caught in an inescapable network of mutuality, tied in a single garment of destiny.” One might also say that we are in a web of mutuality … a “Webb” (pun intended) that has the potential to unite the world in understanding, discovery and awe.
As I reflect on my multiple international engagements over the past month, including discussions on the human Journey to Mars with representatives from 17 space agencies at the International Astronautical Congress in Guadalajara Mexico, and participating this week in the second U.S.-China Civil Space Dialogue, I can’t help but feel deep pride in NASA’s accomplishments as a global leader in space and aeronautics research. Currently, NASA has over 750 active agreements with more than 120 nations around the world for cooperation that contributes to almost all aspects of NASA’s activities. The relationships NASA has developed over more than 50 years of international cooperation and successful implementation of thousands of international agreements have set the stage for robust international participation in NASA’s plans for the human Journey to Mars.
One key aspect of our exploration program is a sustainable, affordable expansion of human presence into the solar system – not a piecemeal mission or two, but a foundation for ongoing pioneering efforts that will evolve as we learn from earlier missions. NASA is proud of the substantial progress we have made in developing the next generation of human spaceflight assets – the Orion crew capsule, the Space Launch System (SLS) rocket and Exploration Ground Systems (EGS) to support their launch. Working closely with partners from 14 nations we’ve also been using the International Space Station (ISS) to prepare our astronauts to explore beyond low-Earth orbit (LEO) and into the proving ground of cislunar space.
I was pleased this week to participate in the second U.S.-China Civil Space Dialogue along with the State Department’s Deputy Assistant Secretary Jonathan Margolis, Mr. Tian Yulong, Secretary-General of the China National Space Administration (CNSA), and distinguished members of the Chinese and American delegations.
I expressed my congratulations on behalf of the entire NASA family to Mr. Tian on last month’s launch of the Tiangong-2 laboratory and the recent launch of the Shenzhou-11 crewed mission — major milestones in China’s human space flight program.
I visited China this past August and one of the main goals of that visit was to conclude the Air Traffic Management agreement between NASA and the Chinese Aeronautical Establishment (CAE). While not a topic included under the Civil Space Dialogue, this agreement is an important milestone for NASA’s cooperation with its Chinese counterparts. While I was in China, I was also pleased to discuss the progress in several areas of our cooperation in Earth and space science and to hear about recent developments and plans for China’s human space flight program.
Our human Journey to Mars requires collaboration with many nations, each with their own interests and expertise. Right now, the European Space Agency is providing the service module for the Orion spacecraft that will carry astronauts to deep space in the coming years. We also have hundreds of agreements with other nations in science, such as the many partners providing support and instrumentation for every one of NASA’s missions to Mars, including the Mars 2020 rover, one of many precursors planned to support humans visiting the Red Planet.
NASA’s international partnerships are strong and our exploration strategy is consistent with the Global Exploration Roadmap (GER), released by the international space agencies participating in the International Space Exploration Coordination Group (ISECG). The GER reflects a common vision for deep-space exploration shared by NASA and our international partners and defines common goals for missions to cislunar space, near-Earth asteroids, the moon and Mars.
NASA is well positioned to continue to lead the world to new heights in space and innovations in technology. We have a sustainable plan to extend humanity’s presence into the solar system, advance our capabilities in aeronautics and understand our universe and the planet on which we live that is technically sound and fiscally reasonable. Advancing humanity’s reach is truly a global endeavor and I am confident NASA will maintain its constancy of purpose as we lead by example and engage nations around the world in continuing to make the impossible, possible.
By John Holdren and Charles Bolden
Today, President Obama outlined a vision to CNN for the future of space exploration. Echoing what he said in the 2015 State of the Union address, the President wrote, “We have set a clear goal vital to the next chapter of America’s story in space: sending humans to Mars by the 2030s and returning them safely to Earth, with the ultimate ambition to one day remain there for an extended time.” Later this week, many of the Nation’s top innovators will come together in Pittsburgh at the White House Frontiers Conference, where they will further explore, among other things, how American investments in science and technology will help us settle “the final frontier” – space. But today, we’re excited to announce two new NASA initiatives that build on the President’s vision and utilize public-private partnerships to enable humans to live and work in space in a sustainable way.
In April 2010, the President challenged the country – and NASA – to send American astronauts on a Journey to Mars in the 2030s. By reaching out further into the solar system and expanding the frontiers of exploration, the President outlined a vision for pushing the bounds of human discovery, while also revitalizing the space industry and creating jobs here at home.
To achieve these mutually-reinforcing goals, the President instructed NASA to develop spacecraft and technologies geared toward sending astronauts to deep space, while at the same time partnering with American companies to build a strong space economy. Following the President’s vision, NASA has worked over the past 6 years to help catalyze a vibrant new sector of the economy by enabling the commercial transportation of cargo and soon crew from American soil to the International Space Station. And today, Americans are working at more than a thousand companies across virtually every state to support commercial space initiatives and with them, the growth of a new commercial market in Low Earth Orbit.
On the International Space Station, we’re working “off-the-Earth, for-the-Earth,” leading a broad international coalition of countries and companies in conducting research and demonstrating technologies that hold great promise for everything ranging from sending human beings to Mars to improving eye surgery to purifying drinking water and making communities more resilient when natural disasters strike.
This work aboard the space station is the heart and soul of the first stage of NASA’s Journey to Mars; a stage we call “Earth Dependent.” It is focused on developing technologies and capabilities in earth orbit, where it is still fairly easy for us to directly support humans. But over the next decade, we’ll enter the “Proving Ground” stage, where NASA, leading the way with the international community, will demonstrate and test technologies for the first time in cis-lunar space, the area around the moon, where our astronauts are days or weeks away from Earth, rather than hours. For example, in the mid-2020s, NASA’s Asteroid Redirect Mission will send a robotic spacecraft to a nearby asteroid to test out important exploration technologies such as solar-electric propulsion, conduct scientific and planetary defense experiments, and then return a boulder from the asteroid to an orbit around the Moon for astronauts to study. As the title of this stage indicates, this work serves as necessary preparation for eventual missions that will take humanity even further, to Mars and beyond.
And that brings us to the first thing we’re excited to discuss today. NASA has already begun laying the groundwork for these deep space missions. In 2014 we issued a “broad agency announcement” or “BAA” asking private partners for concept studies and development projects in advanced propulsion, small satellites, and habitation as part of the newly created Next Space Technologies for Exploration Partnerships or “NextSTEP” program. Six companies received awards to start developing habitation systems in response to that “NextSTEP” BAA. The idea is that these habitats or “habs” would evolve into spacecraft capable of sustaining and transporting astronauts on long duration deep space missions, like a mission to Mars. And their development would be achieved through new public-private partnerships designed to build on and support the progress of the growing commercial space sector in Earth orbit. The work done by those companies was so promising that earlier this year, we extended the NextSTEP hab program into Phase 2 and opened it up to new entrants. In August, six companies were selected to produce ground prototypes for deep space habitat modules.
At the same time that we’re working to extend our reach into deep space, we’re also continuing to innovate closer to Earth, by expanding our partnerships with commercial space companies. And that’s the second initiative we are focused on today. Recently, NASA asked the private sector how it might use an available docking port on the ISS. One of the potential uses of such a port would be preparation for one or more future commercial stations in Low Earth Orbit, ready to take over for the Space Station once its mission ends in the 2020s. The private sector responded enthusiastically, and those responses indicated a strong desire by U.S. companies to attach a commercial module to the ISS that could meet the needs of NASA as well as those of private entrepreneurs.
As a result of the responses, this fall, NASA will start the process of providing companies with a potential opportunity to add their own modules and other capabilities to the International Space Station. While NASA prepares for the transition from the Space Station to its successors, the agency is also working to support and grow the community of scientists and entrepreneurs conducting research and growing businesses in space. A vibrant user community will be key to ensuring the economic viability of future space stations.
For humanity to successfully and sustainably settle the “final frontier”, we will need to take advantage of investment and innovation in both the public and private sectors. Neither will handle this immense challenge on its own. The NextSTEP and ISS initiatives are excellent examples of how the two sectors can work together to extend humanity’s reach into space. Make no mistake, the Journey to Mars will be challenging, but it is underway and with each one of these steps, we are pushing the boundaries of exploration and imagination for the Nation.
Tomorrow, the National Museum of African American History and Culture opens its doors to the public. Located on the National Mall, the museum is less than a mile away from NASA’s Washington Headquarters. Recently I spoke to NASA TV about the significance of this occasion, and you can watch a few clips from our conversation below.
On a personal note, I think it’s critically important – and it’s really impressive — that at long last we’re going to have a museum on the Mall that’s dedicated to people of African decent here in the United States. I never in my wildest dreams growing up in Columbia, South Carolina during segregation would have believed that I would be experiencing the opening of a museum dedicated to African American history and culture – let alone during the Administration of America’s first Black president, whom I have the privilege of serving under as NASA’s first African American Administrator.
Because I believe so strongly in its mission, I donated a few personal items to the museum, including my flight suit and mission patch from STS-60, my final space flight and a critical mission to what would become the International Space Station program; a model of the Hubble Space Telescope – what I believe to be the most incredible scientific instrument that humanity has created; rugby shirts from STS-45 and STS-31, among other items.
It’s my hope that young people who visit the museum will be encouraged to reach for new heights in their own lives, and use their dreams as inspiration to work hard, study hard, and refuse to be deterred by failure. The reason that I applied for the Astronaut program many years ago, was that the late, great Dr. Ron McNair – himself a hallmark figure in both African American history and the history of America’s space program — encouraged me to go for it. It is my hope that the objects and displays in this museum will have the same sort of impact on a new generation of future astronauts, artists, engineers, educators, physicists, philosophers, physicians and so forth.
Being the first African American Administrator is all well and good, but I want to make sure I’m not the last. Encouraging more young people from underserved communities to study the STEM subjects of science, technology, engineering and math is one important way to make sure of this. Reminding the next generation that even the sky is not the limit is another.
Best wishes to everyone involved in opening this important new museum. I cannot wait to visit!

NASA is proud to have been named the “Best Place to Work” in the Federal Government (among large agencies) for the past four consecutive years by the Partnership for Public Service. Using the Federal Employee Viewpoint Survey (FEVS) as a focal point for guidance, over time we have developed a positive work culture with a high level of employee engagement through deliberate, proactive initiatives.
I’ve always told our employees that their voices matter. At NASA, it’s especially critical, as much of our work is difficult and dangerous, and sometimes lives are in the balance. We must have a culture where speaking up and providing feedback is encouraged. I’ve made nurturing that culture a centerpiece of my leadership, and we created a Workforce Culture Strategy to communicate and codify these values.
With some 18,000 employees at NASA, getting feedback can be daunting, and the FEVS helps provide a vehicle where people feel they can be candid and offer constructive comments without putting themselves or their jobs at risk. We use it to help offices within our organization to improve and to share their successes. At NASA, we consider ourselves a family and, like any family, there can be some bumps in the road. The FEVS helps us get past them.
Based on last year’s employee feedback, we focused this year on second-level performance reviews to support and encourage fairness in ratings, and we created a Leader’s Handbook to guide supervisors and employees, and to foster organizational health.
I’m still listening – and feel privileged to be working with such a talented, creative workforce. The best part of serving as NASA Administrator continues to be witnessing how open and honest opinions and ideas have changed NASA for the better. Our entire NASA senior leadership team sincerely cares about our workforce’s opinions and is ready to take action.
I want to thank my colleagues and their teams for using the FEVS to make progress on employee engagement. I know agencies across government are using this important tool to make similar strides. All of us need to work each and every day to make sure the talented people who work for the Federal Government feel valued, included, and engaged in their jobs.
This week, I embarked on a visit to Japan for discussions with a variety of senior Japanese government officials about our mutual interest in space exploration. I will also visit NASA’s outstanding partners at JAXA, the Japan Aerospace Exploration Agency.
With more than 30 active agreements in place, NASA and JAXA have one of the strongest, most comprehensive and longest lasting space bilateral relationships of any two nations in the world. One of the greatest illustrations of this partnership is the International Space Station (ISS), orbiting 250 miles (400 kilometers) above the Earth at 17,500 miles per hour (about 28,000 kph) with six astronauts on board as I write this!
NASA’s Journey to Mars is taking shape aboard the orbiting laboratory, where astronauts from different countries are working together to advance research and technology that will allow future astronauts to travel deeper into space, at the very same time we create jobs and improve our quality of life here on Earth.
Japan and the United States are working together aboard the Space Station with many other international partners – and we will be for the foreseeable future. Today, Japanese astronaut Takuya Onishi and American astronauts Jeff Williams and Kate Rubins are living and working together with their Russian crewmates at the cutting edge of innovation, science and discovery. Their research ‘Off the Earth, For the Earth’ promises to deepen understanding and expand human progress around such areas as medicine, biology, technology, Earth science, material production and communications – and that’s just the short list!
Because leaders in both the U.S. and Japan have chosen to extend our Space Station participation through at least 2024, the promise and potential progress that comes out of this research will continue for years to come. In the more immediate future, the research benefitting all of humanity will be bolstered by cargo delivered to station aboard Japan’s upcoming HTV-6 mission (which, as was announced recently, is set to launch in October of this year).
As we consider the bright future of our partnership, I’m very much looking forward to joining our friends at JAXA this week for a ceremony to officially open a control room for Kibo, the Japanese Experiment Module on ISS.
Kibo is, appropriately, a Japanese word meaning “hope,” and I believe that “hope” is an excellent description of the research that’s being conducted aboard the International Space Station and the cooperation that goes into it.
President Obama once said that “hope is the belief that destiny will not be written for us, but by us, by the men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.”
The International Space Station is the embodiment of this sort of hope and effort. Consider this: more than 220 human beings from 18 countries have visited the International Space Station; tens of thousands of people have been involved in its construction and operation; and people from dozens of countries have had their research and experiments flown aboard it.
As we look forward to an exciting future exploring space, I am also enthusiastic about advances the U.S. is making in airspace travel a little closer to Earth. We are in the midst of an incredible moment in the history of aeronautics. With President Obama proposing an historic investment in green aviation, we have an opportunity to make air travel cleaner, greener, safer and quieter – even as our skies grow more crowded and aircraft fly faster.
One of the more important areas of NASA aeronautics research is air traffic management. Our country’s skies will have to absorb an estimated four billion more passengers over the next several decades and it’s essential that we do this without compromising the safety of our skies.
We in the United States are not the only country with an interest in building a more efficient air traffic management system. International commerce depends on air transportation and it is imperative that we work together with partner countries around the world to maximize human resources and investment for the benefit of all humanity.
With this in mind, after my visit to Japan I plan to travel to China to discuss areas of mutual interest in aviation research between NASA and the Chinese Aeronautical Establishment (CAE). This will be part of ongoing conversations that began in November of 2014 and have continued through a NASA-CAE workshop in Beijing that was held in August 2015.
Taken together, our partnerships around the world continue to instill optimism – and inspire hope – about the future of space exploration, aeronautics and our ability to write our own destiny – together.
NASA’s Journey to Mars is about more than sending American astronauts to the Red Planet in the 2030s; it’s about bringing people together here on Earth. It’s about strengthening the American economy and with it the economic security of families throughout our country. It’s also about strengthening our friendships across sectors and also across national borders. This is why I’m fond of reminding virtually every audience to whom I speak that sending humans to Mars requires all hands on deck – government, industry, academic and international partners and citizen scientists – we need everybody.
Today, I’m embarking on a journey of my own — to meet with our global friends in international space agencies, governments, private companies, universities and other forums; folks who are eager to be part of NASA’s Journey to Mars. I plan to carry with me a message of partnership as I remind them of how much the American people value their friendship, especially when it comes to space – which in many ways is the great global connector.
It should not be lost on any of us that for the last decade and a half, human beings from multiple countries have been living and working together on the International Space Station (ISS) in common pursuit of human progress. It certainly is not lost on me, that a girl or boy age 15 or younger has lived every single second of every day of her or his life while human beings have been living and working together in space. Our grandchildren’s children may very well live every day of their own lives while human beings are living and working together on Mars.
For this reason, I’m a firm believer in the soft power that our country is able to demonstrate when we engage in space diplomacy. From our perspective at NASA, one of the most gratifying developments over the past few years has been the increasing number of nations who have joined the global exploration endeavor. Nations large and small, both with and without formal space agencies, have all come to the conclusion that everyone who has a passion for space can find a role and a place where their expertise is critical. In short, every single nation can play a part in our journey to Mars, in our scientific journey of discovery and in the next phase of humanity’s development as a spacefaring people.
Over the course of this trip, I will have the opportunity to discuss NASA’s Journey to Mars with the Israeli Minister of Science, Technology and Space, the Israel Space Agency (ISA), and Israeli innovators, students and entrepreneurs. I’ll also be meeting with students in both Israel and Jordan who participate in the Global Learning and Observations to Benefit the Environment (GLOBE) science and education initiative, of which NASA is a proud partner. I’ll also be traveling to the United Arab Emirates (UAE) to meet with colleagues at the UAE Space Agency. I’ll wrap up this trip with a meeting with NASA partners in the European Space Agency (ESA) at the ESA Council in Paris.
We recognize that NASA provides inspiration to dreamers and doers of all professions everywhere around the world, so we are looking forward to partnering with the U.S. Embassy in Amman and His Royal Highness Crown Prince Al Hussein bin Abdullah II to host a public dialog about NASA’s Journey to Mars while I am in Jordan.
Everywhere I travel, I meet people who are looking to the United States for leadership when it comes to space exploration. Time and again I hear enthusiasm about our Journey to Mars and an appetite for partnership in this remarkable pursuit of progress and possibility.
Together, we can bring humanity to the face of Mars and reach new heights for the benefit of all humankind … and we will.
By NASA Administrator Charles Bolden and
NOAA Administrator Kathryn Sullivan
Climate change is one of the most pressing issues of our generation and it affects every person on Earth. Tracking the changes in the global climate is the basis for understanding its magnitude and extent.
Today’s announcement that NASA and NOAA scientists have determined that 2015 was the hottest year in recorded history underscores how critical Earth observation is. The NOAA-NASA collaboration has served the country very well, from the origin of space-based remote sensing for weather forecasting to the Earth system monitoring and science that are so crucial to tackling the issues of our times. This announcement is a key data point that should make policy makers stand up and take notice — now is the time to act on climate.
The modern temperature record dates back to1880, and 2015 was the warmest year by a long shot.
There has been a lot of talk about the strengthening El Niño in the Pacific Ocean and how that might be supercharging temperatures. El Niño did likely play an important role – but more significantly, 2015’s record temperatures are the result of the gradual, yet accelerating, build-up of carbon dioxide and other greenhouse gases in Earth’s atmosphere. Scientists have been warning about it for decades and now we are experiencing it. This is the second year in a row of record temperatures and what is so interesting is that the warmest temperatures often occur the year after an El Nino, like in 1998 compared to 1997.
Fifteen of the 16 warmest years on record have now occurred since 2001. Temperatures will bounce around from year to year, but the direction of the long-term trend is as clear as a rocket headed for space: it is going up.
This record-breaking moment is a good time to take stock of what we know of our changing planet and why it is important for NASA, NOAA and other federal agencies to continue studying Earth’s climate and how it is changing:
- Sea levels are rising – nearly three inches in the past two decades alone. The successful launch earlier this week of the NOAA-led Jason-3 mission will continue our 23-year record of measuring sea level change from space with remarkable precision. In the coming years and decades, our work to understand how quickly seas are rising will be vital to coastal cities in the U.S., millions of people around the world who live in low-lying areas, and to NASA’s own facilities at Kennedy Space Center, where we will one day launch astronauts to Mars, and other affected facilities such as the Stennis Space Center, Wallops Flight Facility and Michoud Assembly Facility.
- The Arctic ice cap is shrinking. In the 1970s and 80s, NASA scientists pioneered techniques to measure the extent of sea ice at the poles. That new ability quickly gave way to the realization that the Arctic ice cover – which plays a significant role in the planet’s climate and even the weather we experience in the U.S. – is retreating and growing thinner.
- NOAA’s global drifting buoy program and other NOAA and international ocean temperature and land surface temperature measurements have provided the means to measure the temperature at the Earth’s surface, so critical to our survival.
- Ice sheets and glaciers worldwide are shedding ice. Greenland is losing about 300 billion tons of ice per year, according to measurements from NASA’s GRACE mission. Observations from the agency’s Operation IceBridge have helped confirm rapidly accelerating changes in the West Antarctic Ice Sheet and the dramatic retreat of glaciers in Alaska. Given the pace of these changes and their significance for the climate and sea level rise, we need close and continuous monitoring. In 2017, NASA will launch two missions – GRACE-FO and ICESat-2 – that represent a major refresh of our capabilities to observe how ice sheets and glaciers are changing.
Rising temperature is not an isolated effect of rising greenhouse gas levels, and scientists are still studying the full implications of a warmer world. How might patterns of drought and precipitation change? Will ecosystems and species be able to adapt to human-induced climate change? What might these changes mean for wildfires, agriculture and the economy?
Climate change isn’t a problem for the future. Earth’s climate is changing now. At NASA, we use our unique vantage point from space to study the planet as a whole system. NOAA’s scientists are on the ocean, land and in the sky collecting data that help bring clarity. Our job is to answer these kinds of questions, to make the measurements needed to get to those answers and to provide our knowledge and our data freely so the world can address this fundamental challenge.
