A team works together on their project during the 2024 NASA Space Apps Challenge event in in Arequipa, Peru. Teams have two days to respond to the challenges and submit their project for the chance to win one of 10 global awards. NASA invites innovators of all ages to register for the NASA Space Apps Challenge, held on Oct. 4-5. The 2025 theme is Learn, Launch, Lead, and participants will work alongside a vibrant community of scientists, technologists, and storytellers at more than 450 events worldwide. Participants can expect to learn skills to succeed in STEM fields, launch ideas that transform NASA’s open data into actionable tools, and lead their communities in driving technological innovation.
During the NASA Space Apps Challenge, participants in the U.S. and around the world gather at hundreds of in-person and virtual events to address challenges authored by subject matter experts across NASA divisions. These challenges range in complexity and topic, tasking participants with everything from creating machine learning models and leveraging artificial intelligence, to improving access to NASA research, to designing sustainable recycling systems for Mars, and to developing tools to evaluate local air quality here on Earth.
Dr. Yoseline Angel Lopez, a former space apps challenge winner and now an assistant research scientist at NASA’s Goddard Spaceflight Center in Greenbelt, Maryland, can attest that the opportunity to Learn, Launch, Lead goes far beyond the hackathon.
“The NASA Space Apps Challenge gave me and my team a meaningful opportunity to apply science to real-world problems and gain validation from NASA scientists and industry experts,” said Angel.
In 2021, her team’s winning web-app prototype was adopted by Colombia’s Ministry of Agriculture, connecting smallholder farmers with local buyers. The platform also supported agricultural land-use monitoring using satellite imagery.
After the hackathon, project submissions are judged by NASA and space agency experts. Winners are selected for one of 10 global awards.
“Participating in the hackathon is exciting on its own. But when your project can lead to greater opportunities and make a difference in your community, that’s a dream come true,” said Angel. She will return to the 2025 hackathon as a NASA subject matter expert and challenge author, giving a Golden Age of innovators the opportunity to make a difference in their communities through the use of data from NASA and 14 space agency partners.
This year’s partners include: Bahrain Space Agency; Brazilian Space Agency; CSA (Canadian Space Agency); ESA (European Space Agency); ISRO (Indian Space Research Organisation); Italian Space Agency; JAXA (Japan Aerospace Exploration Agency); Mohammed Bin Rashid Space Centre of the United Arab Emirates; National Space Activities Commission of Argentina; Paraguayan Space Agency; South African National Space Agency; Spanish Space Agency; Turkish Space Agency; and the UK Space Agency.
NASA Space Apps is funded by NASA’s Earth Science Division through a contract with Booz Allen Hamilton, Mindgrub, and SecondMuse.

On Tuesday, March 4, 2025, technicians at NASA’s Glenn Research Center in Cleveland help lower student experiments in the 2.2 Second Drop Tower. Credit: NASA/Jef Janis Nineteen teams of students from across the nation in grades 8-12 worked for months in classrooms, labs, basements, and garages for the opportunity to test their projects at NASA’s Glenn Research Center in Cleveland. This spring, the teams’ hard work was put to the test in the 2.2 Second Drop Tower facility at NASA Glenn.
The “2025 Drop Tower Challenge: Paddle Wheel” invited teams to design and build paddle wheels that rotate in water during free fall. The wheels could not rotate by mechanical means. A better understanding of fluid behavior in microgravity could improve spacecraft systems for cooling, life support, and propellants.
On Thursday, May 6, 2025, NASA Glenn Research Center technicians — left to right, John Doehne, Jason West, and Moses Brown — prepare the 2.2. Second Drop Tower for testing student experiments during the 2025 Drop Tower Challenge. Credit: NASA/Jef Janis Based on test performance, analyses, reports, the students’ approach to the challenge, and more, the following teams have been identified as the winners:
First Place: Arth Murarka, Umar Khan, Ishaan Joshi, Alden Al-Mehdi, Rohnin Qureshi, and Omy Gokul (advised by David Dutton), Bellarmine College Preparatory, San Jose, California Second Place: Emma Lai, Keaton Dean, and Oliver Lai (advised by Stephen Lai), Houston, Texas Third Place: Chloe Benner, Ananya Bhatt, and Surabhi Gupta (advised by SueEllen Thomas), Pennridge High School, Perkasie, Pennsylvania “We’re impressed with the variety of designs students submitted for testing in Glenn’s drop tower,” said Nancy Hall, co-lead for the 2025 Drop Tower Challenge. “The teams showed significant creativity and background research through their paddle wheel designs and analysis of results.”
Students from Bellarmine College Preparatory shared how they navigated through the process to earn first place. Using NASA guidelines and resources available to assist students with the challenge, the team submitted a research proposal, including two 3D designs. Learning their team was selected, they reviewed feedback from the NASA staff and set to work.

Credit: Courtesy of Bellarmine College Preparatory To start, students stressed that they conducted a large amount of research and testing of materials to use in their paddle wheels before deciding on the final design.
“I learned that something doesn’t need to be super expensive or complex to work,” said student Umar Khan. “We found that white board sheets or packing peanuts — just household items — can be effective [in the design].”
Student Arth Murarka added, “Our original design looks a lot different from the final.”
Bellarmine staff member and team advisor David Dutton helped the students get organized in the beginning of the process, but said they worked independently through much of the project.

NASA technicians then tested how the paddle wheels performed in the drop tower, which is used for microgravity experiments.
Students said they studied concepts including capillary physics and fluid dynamics. They also learned how to write a research paper, which they said they will appreciate in the future.
The team dedicated a lot of time to the project, meeting daily and on weekends.
“We learned a lot of useful skills and had a lot of fun,” Murarka said. “It was definitely worth it.”

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.
