Dave Sheppard and Carolina Chism take us on a tour of the historic Magnetic Test Facility, located deep in the woods miles away from Goddard's main campus.
This facility is where we test magnetometers for everything from Apollo rovers to modern Mars missions. Magnetometers use electric currents to measure magnetic fields on Earth and elsewhere.
The Magnetic Test Facility is built of non-magnetic materials, with massive coils to zero out Earth's magnetic field. It sits about 2 miles away from the rest of Goddard, surrounded by trees to help protect it from magnetic interference from things like power lines, and other tech.
Earth's magnetic field plays a role in making our planet habitable, protecting us from some of the Sun's harsh radiation. Understanding our own magnetic field, the way it interacts with the solar wind, and magnetic spots on other planetary bodies will help us explore the Moon and beyond.

![NASA’s Illuminate: Solar Orbiter Reveals Sun’s Poles For The First Time
We just got a brand new view of the Sun! ☀️ 👀
ESA/NASA’s Solar Orbiter has revealed the first-ever images of the Sun’s polar regions, previously hidden parts of the Sun newly visible thanks to the spacecraft’s uniquely “tilted” orbit.
The new images showcase a surprisingly splotchy mix of magnetic fields at the Sun’s poles. It’s a sign that our Sun is in its most chaotic phase, right in the middle of “flipping” its entire magnetic field upside down. 🔃
With its new vantage point, Solar Orbiter will be the first spacecraft to watch this flipping process happen at the Sun’s poles. The data will give new insight into the forces driving solar eruptions that affect Earth.
NASA’s Illuminate: Out-of-this-world images shining light on our Sun and solar system.

![At Lands Edge - Tracking Coastal Ecosystem with Landsat
Coastal ecosystems store carbon, buffer storms, and shelter marine life—but they’re also among the most threatened environments on Earth. For over 50 years, the NASA–USGS Landsat program has tracked their health, from monitoring Florida’s mangroves after hurricanes to uncovering the surprising growth of eelgrass meadows in Canada. Today, Landsat even powers tools like STREAM, putting coastal water quality data at your fingertips.

![NASA Explains Gamma-ray Bursts
Watch to learn more about gamma-ray bursts, the most powerful explosions in the cosmos. They first came to the attention of astronomers in the 1970s when new satellites detected this surprising phenomenon. Over decades, scientists have found that these blasts could be detected somewhere in the sky almost every day, and that they were both extremely distant — the closest known erupted over 100 million light-years away — and enormously powerful. Gamma-ray bursts are now linked to the explosive deaths of massive stars and to mergers of compact objects, like neutron stars and black holes, but many puzzles remain.

![NASAs Roman Space Telescope Hardware Highlights: Summer/Fall 2025
This video, covering the second half of 2025, opens with a person entering NASA’s Goddard Space Flight Center’s largest clean room, the Spacecraft Systems Development and Integration Facility. The room is a class 10,000 clean room with over one million cubic feet of space.
The outside half of Roman, called OSD, contains the solar panels & protective layers. The Deployable Aperture Cover protects the mirrors during launch and then unfolds to help shield them from sunlight does a test deployment. During this test, lines connect to it & pull upward to negate Earth’s gravitational forces, which Roman will not experience in space. Then the Solar Array Sun Shield panels deploy. There are four panels that move. They fold against the spacecraft to fit in the rocket fairing & deploy in space to make a large flat plane that both collects light to generate electricity and helps keep the rest of Roman cool.
In preparation for additional testing, technicians put a clean tent over OSD and transport it out of the clean room. They push it into the acoustic test chamber where a six-foot-tall horn projects up to 150-decibel sound at varying frequencies. The other tests are on two vibration tables that shake Roman along all three axes: up/down, left/right & forward/backward. Engineers attach hundreds of sensors and run tests of increasing intensity. During and after each test, they carefully study the data to make sure that Roman is behaving as they anticipated.
While these tests occur, Roman’s inside half, containing the mirrors, instruments & support equipment, move into Goddard’s largest thermal vacuum chamber, the SES (Space Environment Simulator). This 40-foot-tall chamber can simulate the vacuum of space & the wide temperature range that Roman will experience there: from -310° F (-190° C) to 302° F (150° C). The move to the chamber happens without a clean tent, so the entire path was cleaned, and all the workers dress in full clean-room garb to ensure that no dirt contaminates the sensitive parts of the spacecraft. Once the two layers of doors are sealed, Roman spends 72 days inside running through tests at various temperatures and with equipment turned on to ensure that it works at low temperature in a vacuum. A special array installed above the mirror projects light that engineers use to test the optics and sensors.
After leaving the SES chamber and returning to the SSDIF, Roman’s primary and secondary mirrors are carefully cleaned and inspected. It is a balance to get the mirrors as clean as possible while not cleaning too aggressively and damaging the delicate surfaces. The mirrors are cleaned both horizontally with a gentle vacuum cleaner and vertically with brushes. After this cleaning, every inch is visually inspected and photographed to record the exact optical characteristics. This was the last time the primary mirror would be accessible.
Finally, in late November, Roman’s two halves are joined together to form the complete observatory. The process takes the better part of a day. Two guide poles are installed on the inside half to help direct OSD down onto it. At various times, the clearances between the two halves are only a few inches. With the observatory complete, it begins preparing for another round of deployments and testing.
On track to launch in the fall of 2026, Roman is NASA’s next flagship astrophysics mission. An infrared survey telescope with the same resolution as Hubble but at least 100 times the field of view, Roman is being built and tested at NASA Goddard. Partners from around the globe are contributing to this effort.

![NASA’s Illuminate: The Moon’s Tan Lines
Did you know the Moon has “tan lines”?
These tan lines, which feature bright tendrils and swirls amid darkened areas, are caused by the Sun. But that’s only half of the story. These weathered patches also give us clues as to what’s going on below the lunar surface.

![NASAs Swift Mission Gets a Boost
After more than two decades, the orbit of NASA’s Neil Gehrels Swift Observatory has entered a phase of rapid decay. While NASA could allow the observatory to re-enter Earth’s atmosphere, as many missions do at the ends of their lifetimes, this situation has presented an opportunity to advance American spacecraft servicing technology while also extending the life of a productive science mission. To accomplish this, NASA awarded the U.S. company Katalyst Space a contract in September 2025 to attempt to raise Swift’s orbit.
