The European Space Agency (ESA) is ready to guide the ESA/NASA Solar Orbiter spacecraft through its closest encounter with Venus so far.
Today’s flyby will be the first to significantly ‘tilt’ the spacecraft’s orbit and allow it to see the Sun’s polar regions, which cannot be seen from Earth.
Studying the Sun’s poles will improve our understanding of solar activity, space weather, and the Sun-Earth connection.

Sols 4454-4457: Getting Ready to Fill the Long Weekend with Science
NASA’s Mars rover Curiosity acquired this image, which includes the pyramid-shaped rock at left in the photo, the science target dubbed “Pyramid Lake,” using its Left Navigation Camera. The rover acquired the image on sol 4452, or Martian day 4,452 of the Mars Science Laboratory mission, on Feb. 13, 2025, at 14:22:06 UTC. NASA/JPL-Caltech Earth planning date: Friday, Feb. 14, 2025
Curiosity is continuing to make progress along the strategic route, traversing laterally across the sulfate (salt) bearing unit toward the boxwork structures. The team celebrated the completion of another successful drive when we received the downlink this morning, and then we immediately got to work thinking about what’s next. There is a holiday in the United States on Monday, so instead of the typical three-sol weekend plan, we actually planned four sols, which will set us up to return to planning next Tuesday.
The first sol of the plan focuses on remote sensing, and we’ll be taking several small Mastcam mosaics of features around the rover. One of my favorite targets the team picked is a delightfully pointy rock visible toward the left of the Navcam image shown above. The color images we’ll take with Mastcam will give us more information about the textures of this rock and potentially provide insight into the geologic forces that transformed it into this comical shape. The team chose what I think is a very appropriate name for this Martian pyramid-shaped target — “Pyramid Lake.” The terrestrial inspiration behind this name is a human-made reservoir (lake) near Los Angeles with a big (also human-made) pyramidal hill in it.
On the second sol of the plan, we’ll use the instruments on Curiosity’s arm to collect data of rock targets at our feet, including “Strawberry Peak,” a bumpy piece of bedrock, “Lake Arrowhead,” a smooth piece of bedrock, and “Skyline Trail,” a dark float rock. ChemCam will also collect chemical data of Skyline Trail, “Big Tujunga” — which is similar to Strawberry Peak — and “Momyer.” We’ll also take the first part of a 360-degree color mosaic with Mastcam!
In the third sol of the plan, we’ll complete the 360-degree mosaic and continue driving to the southwest along our strategic route. The fourth sol is pretty quiet, with some atmospheric observations and a ChemCam AEGIS. Atmospheric observations are additionally sprinkled throughout other sols of the plan. This time of year we are particularly interested in studying the clouds above Gale crater!
I’m looking forward to the nice long weekend, and returning on Tuesday morning to see everything Curiosity accomplished.

Launched just two months ago and still in the process of being commissioned for service, the Copernicus Sentinel-1C satellite is, remarkably, already showing how its radar data can be used to map the shape of Earth’s land surface with extreme precision.
These first cross-satellite ‘interferometry’ results assure its ability to monitor subsidence, uplift, glacier flow, and disasters such as landslides and earthquakes.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 lights up the night sky with its unique Mach diamonds, also known as shock diamonds, during maximum afterburner testing at Lockheed Martin Skunk Works in Palmdale, California. The test demonstrated the engine’s ability to generate the thrust required for supersonic flight, advancing NASA’s Quesst mission.Credit: Lockheed Martin/Gary Tice NASA’s X-59 quiet supersonic research aircraft took another successful step toward flight with the conclusion of a series of engine performance tests.
In preparation for the X-59’s planned first flight this year, NASA and Lockheed Martin successfully completed the aircraft’s engine run tests in January. The engine, a modified F414-GE-100 that powers the aircraft’s flight and integrated subsystems, performed to expectations during three increasingly complicated tests that ran from October through January at contractor Lockheed Martin’s Skunk Works facility in Palmdale, California.
“We have successfully progressed through our engine ground tests as we planned,” said Raymond Castner, X-59 propulsion lead at NASA’s Glenn Research Center in Cleveland. “We had no major showstoppers. We were getting smooth and steady airflow as predicted from wind tunnel testing. We didn’t have any structural or excessive vibration issues. And parts of the engine and aircraft that needed cooling were getting it.”
The tests began with seeing how the aircraft’s hydraulics, electrical, and environmental control systems performed when the engine was powered up but idling. The team then performed throttle checks, bringing the aircraft up to full power and firing its afterburner – an engine component that generates additional thrust – to maximum.

Credit: NASA/Lillianne Hammel A third test, throttle snaps, involved moving the throttle swiftly back and forth to validate that the engine responds instantly. The engine produces as much as 22,000 pounds of thrust to achieve a desired cruising speed of Mach 1.4 (925 miles per hour) at an altitude of approximately 55,000 feet.
The X-59’s engine, similar to those aboard the U.S. Navy’s F-18 Super Hornet, is mounted on top of the aircraft to reduce the level of noise reaching the ground. Many features of the X-59, including its 38-foot-long nose, are designed to lower the noise of a sonic boom to that of a mere “thump,” similar to the sound of a car door slamming nearby.
Next steps before first flight will include evaluating the X-59 for potential electromagnetic interference effects, as well as “aluminum bird” testing, during which data will be fed to the aircraft under both normal and failure conditions. A series of taxi tests and other preparations will also take place before the first flight.
The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to commercial supersonic flight over land by making sonic booms quieter.

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.

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.
