The Incredible Landsats Continue an Unprecedented Record Studying Earth

Every planet changes. To document these changes and what we know about them across millennia is the goal of some of our flagship missions at Mars, Jupiter and elsewhere through our solar system.

Our own planet is another story. Because we live here, those changes in our landscape take on a more urgent, vital concern. Documenting our home from many angles and wavelengths are a fleet of Earth observation satellites operated by many nations as well as commercial entities. NASA and its agency partners help manage an incredible array of these assets.

Now we are targeting Landsat 9 for launch Sept. 27. It carries on a grand tradition that for nearly 50 years has generated a data record of our planet and its changing land, and the imprints that natural disasters and climate change have made visible from space. The world has never seen anything like the Landsat missions before. The continuity of measurements they have provided is an invaluable global asset free to all that helps us understand the very place we live – not just our continent or our nation, but our region and our city and local environment.

Begun in the early days of the 1970s during a time of heightened awareness of threats to our environment, Landsat has continued to remain relevant today. These missions help us see where the place we live – the land we depend on for survival on this ocean world – continues to evolve. We can see the decades of recovery from the Mt. St. Helens eruption, or the effects of fires that raged across the Amazon recently.

Thanks to Landsat we can see how urbanization has changed over two generations. How crops have shifted and where they are grown and how well they’re doing. And how much of our precious water there is to grow them. Wildfires. Hurricanes. Extreme weather of all sorts. We can help see what’s happened and how the environment recovers.

The Landsat missions have had perhaps more impact on peoples’ daily lives than any other Earth observation mission. They’ve had huge economic impact and are the crown jewels in our Earth fleet.

Together with our Landsat partners at the U.S. Geological Survey, we have surveyed our planet rigorously and continuously and stored and shared that information. The earliest geological surveyors plodded across massive landscapes barely scraped by human eyes and now we image the entire Earth in around two days by teaming up with the Landsat 8 satellite we’ll be working with on orbit, and a Sentinel satellite from ESA. Scientists who were not born when Landsat first began to study our planet now look forward to carrying its tradition forward.

Just imagine — at every point in our planet’s life over the past 50 years, Landsat was working hard to help us see our world. Through wars and famines and droughts and storms and manmade events. The data Landsat provides helps us understand how to live better together on the ground. End users of its data are people like farmers and disaster preparedness staff, urban planners, crop managers and food sustainability professionals. And the artists and creative among us who see how an image of a river delta can also be a tree, and about the beauty in the processes constantly shaping our changing planet. #LandsatArt

So join us Sept. 27 at 11:12a.m. PT for the launch of Landsat 9 on Or join our Facebook event page for behind the scenes tours. And please join the global #Landsat conversation about how we study our planet and how that matters to us all.

New Horizons

I visited Europe this past week, from France, to Switzerland and then Spain. It was my first international trip across the Atlantic since the beginning of COVID, the longest time I have ever been away from Europe and Switzerland since I left in 1996 to build a new life on the other side of the Atlantic.

I really missed traveling. No, I do not particularly like sleeping on planes – I am too tall for the seats they build. Sitting there with a mask makes it less comfortable still. And I feel like a small part of my brain was pulled out on numerous swabs used for COVID tests. But it remains important to travel safely and I will do what it takes to protect me and others.

I still admire those flying machines that lift us above the clouds into the sky, and toward distant shores. I recall how long a boat trip would have taken in ancient times for the same trip. And, I think of the interplay of the incredible technologies associated with the first A in NASA – aeronautics.

There are few technologies and industries that bring people together more, and create understanding or even friendships where they seemed elusive at first. “Travel is fatal to prejudice, bigotry, and narrow-mindedness”, said Mark Twain, and that still holds true today.

There were many highlights on this trip – here are just a few.

I enjoyed visiting my friend and colleague, European Space Agency Science Director, Günther Hasinger. This was my first trip to Madrid and I loved it. We spent a day and aligned our programs in ways many phone and Zoom calls cannot. I will never forget our dinner together with wine, cheese and Spanish charcuterie under the Spanish night sky.

I gave a talk at the Swiss Economic Forum aligned with thier conference theme “New Horizons”. It allowed me to spread what we do at NASA to a broad audience. This mission is still the stuff of dreams. One cannot give a talk about new horizons, without talking about Pluto.

My talk was focused on the new horizons we have when exploring the universe – moving the boundary of ignorance back as fast as we know how. And it is about the important of new horizons and unprecedented and urgent collaborations as we focus on our own planet, the Earth, the most beautiful planet we have ever known. The talk was given in (somewhat broken) German. Check it out at this link.

This long awaited trip reminded me of the international and worldwide character NASA Science really does have. Whether it is visiting the company, Maxon, that built electric motors for the Ingenuity helicopter and that enable Perseverance’s sample acquisition, or the international partners in France who helped build the seismology instrument on Mars now, the best science is done when we do it together, with transparency and trust. I am proud of NASA for its aspirational goal to be the favorite and most reliable collaborator to countries around the globe seeking to explore space. For us at NASA, leadership and partnership is and remains linked, as we have a critical role in efforts of US diplomacy worldwide. We have trusted friends in so many countries, friends we look forward to seeing in person as soon as it is feasible and safe!
