NASA Two Stars in Solar Science
It takes a lot of work to make space missions happen. Hundreds or even thousands of experts work as a team to put together the spacecraft. Then it has to be tested in conditions similar to space, to be sure that it can survive out there once it is launched. Fixing big issues that pop up after launch is either impossible or very difficult, so it is important that everything works before the mission gets to space.
The Parker Solar Probe and Solar Orbiter missions study the Sun from different points of view. Parker is led by NASA and was built to fly into the upper atmosphere of the Sun, called the corona. Solar Orbiter is led by the European Space Agency (ESA) and has gotten our first peek at the Sun’s poles. Together, they both provide a deeper understanding of the Sun and how it affects the rest of the solar system.
A New Way of Seeing
It takes a lot of teamwork to build and launch any space mission, and Solar Orbiter was no different. It also had to go through a lot of testing in conditions similar to outer space before it made its final journey to the launch site.
The Solar Orbiter mission has taken the highest-ever-resolution images of the Sun and recently sent back the first ever close-up images of the Sun’s poles. It has also studied the solar wind to see what it is made of and helped scientists find out where on the Sun the solar wind comes from. Working hand-in-hand with Parker, it has also shown how the solar wind gets a magnetic “push” that increases its total speed.
An infographic showing the ten scientific instruments carried aboard Solar Orbiter European Space Agency To get all of this done, the spacecraft carries ten different scientific instruments on its voyage around the Sun. These instruments work together to provide a total overview of our star. Six of them are remote-sensing instruments (above in gold), which “see” the Sun and return imagery to Earth. The other four are what’s called in-situ instruments (above in pink), which measure the environment all around the spacecraft. This includes the solar wind, and the electric and magnetic fields embedded within it.
Faster and Closer Than Ever Before
The Parker Solar Probe was named for Dr. Eugene N. Parker, who pioneered our modern understanding of the Sun. In the mid-1950s, Parker developed a theory that predicted the solar wind. The probe named after him is designed to swoop within 4 million miles (6.5 million kilometers) of the Sun’s surface to trace its energy flow, to study the heating of the corona, and to explore what accelerates the solar wind.
To get all this done, the probe has to survive the blazing hot corona. It can get up to about 2 million °F (1.1 million °C)! Parker uses high-tech thermal engineering to protect itself, including an eight-foot diameter heat shield called the Thermal Protection System (TPS). The TPS is made of two panels of carbon composite with a lightweight 4.5-inch-thick carbon foam core. This heat shield sandwich keeps things about 85 °F (29 °C) in its shadow, even though the Sun-facing side reaches about 2,500 °F (1,377 °C)!
In 2018, the Parker Solar Probe became the fastest spacecraft ever built, at about 430,000 miles per hour (700,000 kilometers per hour). It also got seven times closer to the Sun than any other spacecraft, getting within 3.8 million miles (6.2 million kilometers). It made this record-breaking close encounter on Christmas Eve of 2024.
From Yesterday to Tomorrow
The Parker Solar Probe was launched on August 12, 2018, and Solar Orbiter was launched on February 10, 2020. Both of them took off from Cape Canaveral Air Station in Florida. Some pieces of Solar Orbiter were transported in trucks, but the completed spacecraft made the journey from Europe to the U.S. on a gigantic Antonov cargo plane designed especially for transporting spacecraft.
Together, these spacecraft have done a lot to improve our knowledge of the Sun. Both missions are currently in their main operational phase, with projected end-of-mission sometime in 2026, and could continue returning data for a few years to come.

Curiosity Blog, Sols 4595-4596: Just Another Beautiful Day on Mars
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on July 9, 2025 — Sol 4594, or Martian day 4,594 of the Mars Science Laboratory mission — at 11:03:48 UTC. NASA/JPL-Caltech Written by Ashley Stroupe, Mission Operations Engineer at NASA’s Jet Propulsion Laboratory
Earth planning date: Wednesday, July 9, 2025
In today’s plan, we have a little bit of everything. With it being winter still, we are taking advantage of the ability to let the rover sleep in, doing most of the activities in the afternoon when it is warmer and we need less heating. As the Systems Engineer (Engineering Uplink Lead) today, I sequenced the needed heating and some other engineering housekeeping activities.
We start off with an extensive remote science block with Mastcam imaging of a nearby trough to look for potential sand activity. There is color imaging of a displaced block, “Ouro,” near a circular depression — could this be a small crater? Mastcam also takes a look at a ridge “Volcán Peña Blanca” to look at the sedimentary structures, which may provide insights into its formation. ChemCam LIBS and Mastcam team up to look at the “Los Andes” target, which is the dark face of a nearby piece of exposed bedrock. ChemCam RMI and Mastcam check out a distant small outcrop to examine the geometry of the layers. We also throw in environmental observations, a Mastcam solar Tau and a Navcam line-of-site looking at dust in the atmosphere. After a nap, Curiosity will be doing some contact science activities on “Cataratas del Jardín” and “Rio Ivirizu” bedrock targets. Looking at two nearby targets for variability can help us understand the local geology. Cataratas del Jardín gets a brushing to clear away the dust before both targets are examined by MAHLI and APXS. Fortunately for the Arm Rover Planner, both of these targets are fairly flat and easy to reach. Before going to sleep for the night, Curiosity will stow the arm to be ready for driving on the next sol.On the second sol, there is more remote science. ChemCam LIBS and Mastcam will examine “Torotoro,” another piece of layered bedrock. ChemCam RMI will take a mosaic of “Paniri,” which is an interesting incision in the rock that is filled with another material. There are also environmental observations, a Navcam dust devil survey and a suprahorizon movie. After another nap, Curiosity is getting on the road. We’re heading southwest (direction shown in the image) about 50 meters (about 164 feet), but we need to sneak between sandy pits and skirt around some terrain that we can’t see behind. The terrain here provides pretty nice driving, though, without a lot of big boulders, steep slopes, or pointy rocks that can poke holes in our wheels. After the standard post-drive imaging for our next plan, there are some Navcam observations to look for clouds and our normal look under the rover with MARDI before Curiosity goes to sleep for the night.

Linking Satellite Data and Community Knowledge to Advance Alaskan Snow Science
Seasonal snow plays a significant role in global water and energy cycles, and billions of people worldwide rely on snowmelt for water resources needs, including water supply, hydropower, agriculture, and more. Monitoring snow water equivalent (SWE) is critical for supporting these applications and for mitigating damages caused by snowmelt flooding, avalanches, and other snow-related disasters. However, our ability to measure SWE remains a challenge, particularly in northern latitudes where in situ SWE observations are sparse and satellite observations are impacted by the boreal forest and environmental conditions. Despite limited in situ SWE measurements, local residents in Arctic and sub-Arctic regions provide a vast and valuable body of place-based knowledge and observations that are essential for understanding snowpack behavior in northern regions.
As part of a joint NASA SnowEx, NASA’s Minority University Research and Education Project (MUREP) for American Indian and Alaska Native STEM (Science, Technology, Engineering, & Mathematics) Engagement (MAIANSE), and Global Learning & Observations to Benefit the Environment (GLOBE) Program partnership, a team of scientists including NASA intern Julia White (NASA Goddard Space Flight Center, University of Alaska Fairbanks), Carrie Vuyovich (NASA Goddard Space Flight Center), Alicia Joseph (NASA Goddard Space Flight Center), and Christi Buffington (University of Alaska Fairbanks, GLOBE Implementation Office) is studying snow water equivalent (SWE) across Interior Alaska. This project combines satellite-based interferometric synthetic aperture radar (InSAR) data, primarily from the Sentinel-1 satellite, with ground-based observations from the Snow Telemetry (SNOTEL) network and GLOBE (Global Learning Observations to Benefit the Environment). Together, these data sources help the team investigate how SWE varies across the landscape and how it affects local ecosystems and communities. The team is also preparing for future integration of data from NASA’s upcoming NISAR (NASA ISRO Synthetic Aperture Radar) mission, which is expected to enhance SWE retrieval capabilities.
After a collaborative visit to the classroom of Tammie Kovalenko in November 2024, Delta Junction junior and senior high school students in vocational agriculture (Vo Ag) classes, including members of Future Farmers of America (FFA), began collecting GLOBE data on a snowdrift located just outside their classroom. As the project progressed, students developed their own research questions. One student, Fianna Rooney, took the project even further — presenting research posters at both the GLOBE International Virtual Science Symposium (IVSS) and both the FFA Regional and National Conventions. Her work highlights the growing role of Alaskan youth in science, and how student-led inquiry can enrich both education and research outcomes. (This trip was funded by the NASA Science Activation Program’s Arctic and Earth SIGNs – STEM Integrating GLOBE & NASA – project at the University of Alaska Fairbanks.)
In February 2025, the team collaborated with Delta Junction Junior High and High School students, along with the Delta Junction Trails Association, to conduct a GLOBE Intensive Observation Period (IOP), “Delta Junction Snowdrifts,” to collect Landcover photos, snow depth, and snow water equivalent data. Thanks to aligned interests and research goals at the Alaska Satellite Facility (ASF), the project was further expanded into Spring 2025. Collaborators from ASF and the Alaska Center for Unmanned Aircraft Systems Integration (ACUASI) collected high resolution airborne data over the snowdrift at the Delta Junction Junior and Senior High School. This complementary dataset helped strengthen connections between satellite observations and ground-based student measurements.
This effort, led by a NASA intern, scientists, students, and Alaskan community members, highlights the power of collaboration in advancing science and education. Next steps will include collaboration with Native Alaskan communities near Delta Junction, including the Healy Lake Tribe, whose vast, generational knowledge will be of great value to deepening our understanding of Alaskan snow dynamics.
