If humans are planning to live off-world and colonise planets like Mars, that includes having children. But deep space and the surface of Mars aren't Earth, and there are several hazards that a gestating foetus will face, mainly microgravity and galactic cosmic rays. In a new paper, a researcher breaks down pregnancy into 10 sequential stages, evaluating what the implications of those conditions would be at each step. The author suggests that radiation would be the bigger risk.

Imagine if every time you turned on your phone, it accidentally jammed radio telescopes trying to detect alien signals. That's essentially what's happening as thousands of internet satellites flood Earth's orbit, creating electronic noise that's drowning out the whispers from black holes, distant galaxies, and the Big Bang itself. A massive new study reveals that our quest to connect every region of the planet is accidentally sabotaging our ability to answer the biggest questions in science and the problem is getting worse with every satellite launch.

Curiosity Blog, Sols 4616-4617: Standing Tall on the Ridge NASA’s Mars rover Curiosity acquired this image, showing the impressive landscape it is currently navigating. The rover is standing tall on the ridge, its shadow casting forward, and Mount Sharp towers over the scene in the distance. Curiosity captured this image with its Front Hazard Avoidance Camera (Front Hazcam) on July 30, 2025 — Sol 4614, or Martian day 4,614 of the Mars Science Laboratory mission — at 02:24:02 UTC.

Earth planning date: Wednesday, July 30, 2025

The day started with a little celebration of NISAR, a new Earth observation satellite that made it successfully into orbit a few hours before our planning started. We joined in by saying “GO NISAR, NASA, JPL, and ISRO” (the Indian Space Research Organisation, NASA’s mission partner, which launched NISAR). Learn more at the NISAR mission hub. Although our team studies Mars, Earth is a planet, too, and we are very happy for our colleagues’ successful launch!

On Mars, it’s still winter and the topic of every planning is how to maximize the science we can do given the increased power needs for heating our rover at this time of the year. Curiosity is parked on top of the main ridge, nicknamed the “autobahn.” It turned out to be not as smooth as its terrestrial namesake, as you can see in the image above. To arrive at this parking position, our rover drivers decided to take a small detour down into a flatter area and back up onto the ridge for safe off-road driving. The rover’s parking position allows for beautiful views around us, laying out the land of hollows and ridges perfectly to plan our next steps and to admire Mount Sharp in the distance.

Standing tall on the ridge, we got several investigations of the ridge-forming materials into today’s plan. APXS, MAHLI, and ChemCam are all teaming up to investigate the target “El Salto.” This is a target that could get us a glimpse into what formed the central line that is running along the big ridge. If you look closely at the images there are subtle differences in color and texture, and we are all curious whether that translates to chemical differences, too.

Of course, it’s not all about chemistry. Mastcam is busy documenting a small mound, and its context with veins and the hollow surrounding it, at the target “Llullaillaco.” The target “Cementerio De Tortugas” will capture sand ripples within a trough area, there is an extension of the workspace imaging in the plan for more context of today’s observations, and finally the ridge intersection is of interest at the target “Villa Abecia.” Of course, Mastcam didn’t forget the documentation of the ChemCam target “El Salto” and the AEGIS target from the last plan. Speaking of ChemCam: It’s using its imaging capabilities to document the side of the ridge to give finer details of the sedimentary structures of the target “Llullaillaco.”

Atmospheric observations are also of highest interest at this time of the day. We continue our atmospheric monitoring by looking for dust devils as well as up toward the clouds in a joint observation with the CASSIS instrument, which is aboard the European Space Agency’s Trace Gas Orbiter. In addition, Curiosity continues to monitor wind and temperature throughout the plan, and the DAN (dynamic albedo of neutrons) instrument observes the rocks underneath the rover for their water content.

After completing the observations at the current parking location, Curiosity will be driving off the ridge again, but this time to stay within the hollow, so we can make observations of the material that forms those hollows. Let’s see if we can find any chemical differences between those materials that might explain why one is standing up tall and the other one is weathering out. If you want to get a better impression of what I am talking about when I say ridges and troughs, have a look at this recent navigation camera mosaic.

NASA is calling on the public to help shape the future of lunar exploration by designing the next generation of wheels capable of navigating the moon's harsh terrain.

Imagine 3D printing an entire building from Moon dust, or having robots construct disaster relief shelters while humans stay safely away from danger. Imagine construction sites where materials never run out because they're literally made from the dirt beneath your feet, and where every structure is built with manufacturing level precision. What sounds like science fiction is becoming reality as engineers solve the ultimate construction puzzle, building on other planets. The innovations being pioneered for lunar bases and Martian colonies are about to transform every construction site on our home planet.

STEM Educators Are Bringing Hands-On NASA Science into Virginia Classrooms

Professional learning experiences are integral to the enhancement of classroom instruction. Teachers, at the forefront of Science, Technology, Engineering, & Mathematics (STEM) education, play a key role in the advancement of STEM learning ecosystems and citizen science.

On June 24-25, 2025 – despite a major east coast heat wave – twenty-four educators from eight school districts in the Hampton Roads region of southeastern Virginia (Newport News, Hampton City, Virginia Beach City, Isle of Wight County, Poquoson City, Norfolk, York County, and Suffolk Public Schools) converged at the National Institute of Aerospace (NIA) in Hampton, VA for a professional development workshop led by experts from NASA Langley Research Center and the NASA Science Activation program’s NIA-led NASA eClips team. Developed in collaboration with another NASA Science Activation team, GLOBE (Global Learning and Observations to Benefit the Environment) Mission Earth, and with support from the Coastal Virginia STEM Hub (COVA STEM) – a “STEM learning ecosystem targeting pre-K to adult residents in Coastal Virginia” – this two-day training, also provided comprehensive resources, including lesson plans, pacing guides, classroom activities, and books, all designed for integration into Hampton Roads classrooms.

The NASA Langley team led workshop participants through a training about GLOBE, a program dedicated to advancing Earth System science through data collected by volunteer members of the public, also known as ‘citizen scientists’. GLOBE invites educators, students, and members of the public worldwide (regardless of citizenship) to collect and submit cloud, surface temperature, and land cover observations using the GLOBE Observer app – a real-time data collection tool available right on their smartphones. These observations are then used to help address scientific questions at local, regional, and global scales. Through this training, the educators participated in K-20 classroom-friendly sample lessons, hands-on activities, and exploring the GLOBE Observer app, ultimately qualifying them as GLOBE Certified Educators. Earth System science lessons, activities, and information on how to download the GLOBE Observer citizen science app are available on the GLOBE website. Similarly, NASA eClips, which focuses on increasing STEM literacy in K-12 students, provided educators with free, valuable, standards-based classroom resources such as educator guides, informational videos, engineering design packets, and hands-on activities, which are available to educators and students alike on the NASA eClips’ website. Throughout the training, educators collaborated in grade-level groups, brainstorming new ways to integrate these standards-based NASA science resources.

One educator envisioned incorporating GLOBE’s cloud resources and supportive NASA eClips videos into her energy budget unit. Others explored modifying a heat-lamp experiment to include humidity and heat capacity. One teacher enthusiastically noted in response to a GLOBE urban heat island lesson plan, “The hands-on elements are going to be really great deliverables!” The creative energy and passion for education were palpable.

The dedication of both NIA and NASA Langley to education and local community support was evident. This professional learning experience offered educators immediately-applicable classroom activities and fostered connections among NASA science, NASA eClips, the GLOBE Program, and fellow educators across district lines. One educator highlighted the value of these networking opportunities, stating, “I do love that we’re able to collaborate with our colleagues so we can plan for our future units during the school year”. Another participant commented, “This is a great program…I am going to start embedding [this] in our curriculum.”

GME (supported by NASA under cooperative agreement award number NNX16AC54A) and NASA eClips (supported by NASA under cooperative agreement award number NNX16AB91A) are part of NASA’s Science Activation Portfolio.
