What You Need To Know About the March 2025 Total Lunar Eclipse
The Moon will pass into Earth’s shadow and appear to turn red on the night of March 13 or early in the morning of March 14, depending on time zone. Here’s what you need to know about the total lunar eclipse.
The March 2025 total lunar eclipse will take place between late night on March 13 and early morning on March 14 across several time zones. In this data visualization, the Moon moves from right to left, passing through Earth’s shadow and leaving in its wake an eclipse diagram with the times (in UTC) at various stages of the eclipse.

A lunar eclipse occurs when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. In a total lunar eclipse, the entire Moon falls within the darkest part of Earth’s shadow, called the umbra. When the Moon is within the umbra, it turns red-orange. Lunar eclipses are sometimes called “Blood Moons” because of this phenomenon.

You don’t need any special equipment to observe a lunar eclipse, although binoculars or a telescope will enhance the view. A dark environment away from bright lights makes for the best viewing conditions.
This eclipse will be visible from Earth’s Western Hemisphere.

Milestone: What’s happening: Penumbral eclipse begins (8:57pm PDT, 11:57pm EDT, 03:57 UTC) The Moon enters the Earth’s penumbra, the outer part of the shadow. The Moon begins to dim, but the effect is quite subtle. Partial eclipse begins (10:09pm PDT, 1:09am EDT, 05:09 UTC) The Moon begins to enter Earth’s umbra and the partial eclipse begins. To the naked eye, as the Moon moves into the umbra, it looks like a bite is being taken out of the lunar disk. The part of the Moon inside the umbra will appear very dark. Totality begins (11:26pm PDT, 2:26am EDT, 06:26 UTC) The entire Moon is now in the Earth’s umbra. The Moon will turn a coppery-red. Try binoculars or a telescope for a better view. If you want to take a photo, use a camera on a tripod with exposures of at least several seconds. Totality ends (12:31am PDT, 3:31am EDT, 07:31 UTC) As the Moon exits Earth’s umbra, the red color fades. It will look as if a bite is being taken out of the opposite side of the lunar disk as before. Partial eclipse ends (1:47am PDT, 4:47am EDT, 08:47 UTC) The whole Moon is in Earth’s penumbra, but again, the dimming is subtle. Penumbral eclipse ends (3:00am PDT, 6:00am EDT, 10:00 UTC) The eclipse is over. Data visualization showing a telescopic view of the Moon as the March 2025 total lunar eclipse unfolds.

The same phenomenon that makes our sky blue and our sunsets red causes the Moon to turn reddish-orange during a lunar eclipse. Sunlight appears white, but it actually contains a rainbow of components—and different colors of light have different physical properties. Blue light scatters relatively easily as it passes through Earth’s atmosphere. Reddish light, on the other hand, travels more directly through the air.
When the Sun is high on a clear day, we see blue light scattered throughout the sky overhead. At sunrise and sunset, when the Sun is near the horizon, incoming sunlight travels a longer, low-angle path through Earth’s atmosphere to observers on the ground. The bluer part of the sunlight scatters away in the distance (where it’s still daytime), and only the yellow-to-red part of the spectrum reaches our eyes.
During a lunar eclipse, the Moon appears red or orange because any sunlight that’s not blocked by our planet is filtered through a thick slice of Earth’s atmosphere on its way to the lunar surface. It’s as if all the world’s sunrises and sunsets are projected onto the Moon.
During a total lunar eclipse, the Moon is reddened by sunlight filtered through Earth’s atmosphere. NASA’s Scientific Visualization Studio What else can I observe on the night of the eclipse?
Look to the western sky on the night of the eclipse for a glimpse of planets Jupiter and Mars. The Moon will be in the constellation Leo, under the lion’s hind paw, at the beginning of the eclipse; soon afterward, it will cross into the constellation Virgo. As Earth’s shadow dims the Moon’s glow, constellations may be easier to spot than usual.

Video: 00:00:40 Back in 2023, we reported on Solar Orbiter’s discovery of tiny jets near the Sun’s south pole that could be powering the solar wind. The team behind this research has now used even more data from the European Space Agency’s prolific solar mission to confirm that these jets exist all over dark patches in the Sun’s atmosphere, and that they really are a source of not only fast but also slow solar wind.
The newfound jets can be seen in this sped-up video as hair-like wisps that flash very briefly, for example within the circled regions of the Sun's surface. In reality they last around one minute and fling out charged particles at about 100 km/s.
The surprising result is published today in Astronomy & Astrophysics, highlighting how Solar Orbiter’s unique combination of instruments can unveil the mysteries of the star at the centre of our Solar System.
The solar wind is the never-ending rain of electrically charged particles given out by the Sun. It pervades the Solar System and its effects can be felt on Earth. Yet despite decades of study, its origin remained poorly understood. Until now.
The solar wind comes in two main forms: fast and slow. We have known for decades that the fast solar wind comes from the direction of dark patches in the Sun’s atmosphere called coronal holes – regions where the Sun’s magnetic field does not turn back down into the Sun but rather stretches deep into the Solar System.
Charged particles can flow along these ‘open’ magnetic field lines, heading away from the Sun, and creating the solar wind. But a big question remained: how do these particles get launched from the Sun in the first place?
Building upon their previous discovery, the research team (led by Lakshmi Pradeep Chitta at the Max Planck Institute for Solar System Research, Germany) used Solar Orbiter’s onboard ‘cameras’ to spot more tiny jets within coronal holes close to the Sun’s equator.
By combining these high-resolution images with direct measurements of solar wind particles and the Sun’s magnetic field around Solar Orbiter, the researchers could directly connect the solar wind measured at the spacecraft back to those exact same jets.
What’s more, the team was surprised to find not just fast solar wind coming from these jets, but also slow solar wind. This is the first time that we can say for sure that at least some of the slow solar wind also comes from tiny jets in coronal holes – until now, the origin of the solar wind had been elusive.
The fact that the same underlying process drives both fast and slow solar wind comes as a surprise. The discovery is only possible thanks to Solar Orbiter’s unique combination of advanced imaging systems, as well as its instruments that can directly detect particles and magnetic fields.
The measurements were taken when Solar Orbiter made close approaches to the Sun in October 2022 and April 2023. These close approaches happen roughly twice a year; during the next ones, the researchers hope to collect more data to better understand how these tiny jets ‘launch’ the solar wind.
Solar Orbiter is a space mission of international collaboration between ESA and NASA, operated by ESA. This research used data from Solar Orbiter’s Extreme Ultraviolet Imager (EUI), Polarimetric and Helioseismic Imager (PHI), Solar Wind Plasma Analyser (SWA) and Magnetometer (MAG). Find out more about the instruments Solar Orbiter is using to reveal more about the Sun.

For astronauts aboard the International Space Station, staying connected to loved ones and maintaining a sense of normalcy is critical. That is where Tandra Gill Spain, a computer resources senior project manager in NASA’s Avionics and Software Office, comes in. Spain leads the integration of applications on Apple devices and the hardware integration on the Joint Station Local Area Network, which connects the systems from various space agencies on the International Space Station. She also provides technical lead support to the Systems Engineering and Space Operations Computing teams and certifies hardware for use on the orbiting laboratory.
Spain shares about her career with NASA and more. Read on to learn about her story, her favorite project, and the advice she has for the next generation of explorers.
Tandra Spain’s official NASA portrait. NASA Where are you from?
I am from Milwaukee, Wisconsin.
Tell us about your role at NASA.
I am the Apple subsystem manager where I lead the integration of applications on Apple devices as well as the hardware integration on the Joint Station Local Area Network. We use a variety of different software but I work specifically with our Apple products. I also provide technical lead support to the Systems Engineering and Space Operations Computing teams. In addition, I select and oversee the certification of hardware for use on the International Space Station, and I research commonly used technology and assess applicability to space operations.
How would you describe your job to family or friends who may not be familiar with NASA?
I normalize living and working in space by providing the comforts and conveniences of living on Earth.
Tandra spain
Computer Resources Senior Project Manager
I get the opportunity to provide the iPads and associated applications that give astronauts the resources to access the internet. Having access to the internet affords them the opportunity to stay as connected as they desire with what is going on back home on Earth (e.g., stream media content, stay in touch with family and friends, and even pay bills). I also provide hardware such as Bluetooth speakers, AirPods, video projectors, and screens.
How long have you been working for NASA?
I have been with the agency for 30 years, including 22 years as a contractor.
What advice would you give to young individuals aspiring to work in the space industry or at NASA?
I have found that there is a place for just about everyone at NASA, therefore, follow your passion. Although many of us are, you don’t have to be a scientist or engineer to work at NASA. Yearn to learn. Pause and listen to those around you. You don’t know what you don’t know, and you will be amazed what gems you’ll learn in the most unexpected situations.
Additionally, be flexible and find gratitude in every experience. Many of the roles that I’ve had over the years didn’t come from a well-crafted, laid-out plan that I executed, but came from taking advantage of the opportunities that presented themselves and doing them to the best of my ability.
Tandra Spain and her husband, Ivan, with NASA astronaut and Flight Director TJ Creamer when she was awarded the Silver Snoopy Award. What was your path to NASA?
I moved to Houston to work at NASA’s Johnson Space Center immediately upon graduating from college.
Is there someone in the space, aerospace, or science industry that has motivated or inspired you to work for the space program? Or someone you discovered while working for NASA who inspires you?
I spent over half of my career in the Astronaut Office, and I’ve been influenced in different ways by different people, so it wouldn’t be fair to pick just one!
What is your favorite NASA memory?
I’ve worked on so many meaningful projects, but there are two recent projects that stand out.
Humans were not created to be alone, and connection is extremely important. I was able to provide a telehealth platform for astronauts to autonomously video conference with friends and family whenever an internet connection is available. Prior to having this capability, crew were limited to one scheduled video conference a week. It makes me emotional to think that we have moms and dads orbiting the Earth on the space station and they can see their babies before they go to bed, when they wake up in the morning, or even in the middle of the night if needed.
In addition, since iPads are used for work as well as personal activities on station, it is important for my team to be able to efficiently keep the applications and security patches up to date. We completed the software integration and are in the process of wrapping up the certification of the Mac Mini to provide this capability. This will allow us to keep up with all software updates that Apple releases on a regular basis and minimize the amount of crew and flight controller team time associated with the task by approximately 85%.
Tandra Spain, her mother, Marva Herndon, and her daughter, Sasha, at her daughter’s high school graduation in 2024. What do you love sharing about station? What’s important to get across to general audiences to help them understand the benefits to life on Earth?
When I speak to the public about the space station, I like to compare our everyday lives on Earth to life on the station and highlight the use of technology to maintain the connection to those on Earth. For example, most people have a phone. Besides making a phone call, what do you use your phone for? It is amazing to know that the same capabilities exist on station, such as using apps, participating in parent teacher conferences, and more.
If you could have dinner with any astronaut, past or present, who would it be?
I would have dinner with NASA astronaut Ron McNair. He graduated from the same university as I did, and I’ve heard great stories about him.
Do you have a favorite space-related memory or moment that stands out to you?
As I mentioned previously, human connection is extremely important. As an engineer in the Astronaut Office, I worked on a project that provided more frequent email updates when Ku-Band communication was available. Previously, email was synced two to three times a day, and less on the weekend. When the capability went active, I sent the first email exchange.
What are some of the key projects you’ve worked on during your time at NASA? What have been your favorite?
There have been so many projects over the past 30 years that I don’t think I could select just one. There is something however, that I’ve done on many occasions that has brought me pure joy, which is attending outreach events as Johnson’s “Cosmo” mascot, especially Houston Astros games.
