Preparations for Next Moonwalk Simulations Underway (and Underwater)
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.

Video: 00:01:51 Space weather ‘reporter’ Vigil will be the world’s first space weather mission to be permanently positioned at Lagrange point 5, a unique vantage point that allows us to see solar activity days before it reaches Earth. ESA’s Vigil mission will be a dedicated operational space weather mission, sending data 24/7 from deep space.
Vigil’s tools as a space weather reporter at its unique location in deep space will drastically improve forecasting abilities. From there, Vigil can see ‘around the corner’ of the Sun and observe activity on the surface of the Sun days before it rotates into view from Earth. It can also watch the Sun-Earth line side-on, giving an earlier and clearer picture of coronal mass ejections (CMEs) heading toward Earth.
Radiation, plasma and particles flung towards Earth by the Sun can pose a very real risk to critical infrastructure our society relies on. This includes satellites for navigation, communications and banking services as well as power grids and radio communication on the ground.
A report by Lloyd’s of London estimates that a severe space weather event, caused by such an outburst of solar activity, could cost the global economy 2.4 trillion dollars over five years.
ESA’s response to this growing threat is Vigil, a cornerstone mission of the Agency’s Space Safety Programme, planned for launch in 2031. Vigil’s data will give us drastically improved early warnings and forecasts, which in turn help protect satellites, astronauts and critical infrastructure on the ground that we all depend on.

6 Min Read NASA’s TRACERS Studies Explosive Process in Earth’s Magnetic Shield
High above us, particles from the Sun hurtle toward Earth, colliding with the upper atmosphere and creating powerful explosions in a murky process called magnetic reconnection. A single magnetic reconnection event can release as much energy as the entire United States uses in a day.
NASA’s new TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission will study magnetic reconnection, answering key questions about how it shapes the impacts of the Sun and space weather on our daily lives.

NASA’s TRACERS mission, or the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, will fly in low Earth orbit through the polar cusps, funnel-shaped holes in the magnetic field, to study magnetic reconnection and its effects in Earth’s atmosphere. NASA’s Goddard Space Flight Center The TRACERS spacecraft are slated to launch no earlier than late July 2025 aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California. The two TRACERS spacecraft will orbit Earth to study how the solar wind — a continuous outpouring of electrically charged particles from the Sun — interacts with Earth’s magnetic shield, the magnetosphere.
What Is Magnetic Reconnection?
As solar wind flows out from the Sun, it carries the Sun’s embedded magnetic field out across the solar system. Reaching speeds over one million miles per hour, this soup of charged particles and magnetic field plows into planets in its path.
“Earth’s magnetosphere acts as a protective bubble that deflects the brunt of the solar wind’s force. You can think of it as a bar magnet that’s rotating and floating around in space,” said John Dorelli, TRACERS mission science lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “As the solar wind collides with Earth’s magnetic field, this interaction builds up energy that can cause the magnetic field lines to snap and explosively fling away nearby particles at high speeds — this is magnetic reconnection.”
Openings in Earth’s magnetic field at the North and South Poles, called polar cusps, act as funnels allowing charged particles to stream down towards Earth and collide with atmospheric gases. These phenomena are pieces of the space weather system that is in constant motion around our planet — whose impacts range from breathtaking auroras to disruption of communications systems and power grids. In May 2024, Earth experienced the strongest geomagnetic storm in over 20 years, which affected high-voltage power lines and transformers, forced trans-Atlantic flights to change course, and caused GPS-guided tractors to veer off-course.
How Will TRACERS Study Magnetic Reconnection?
The TRACERS mission’s twin satellites, each a bit larger than a washing machine, will fly in tandem, one behind the other, in a relatively low orbit about 360 miles above Earth. Traveling over 16,000 mph, each satellite hosts a suite of instruments to measure different aspects of extremely hot, ionized gas called plasma and how it interacts with Earth’s magnetosphere.
An artist’s concept of the twin TRACERS satellites in orbit above Earth. NASA’s Goddard Space Flight Center The satellites will focus where Earth’s magnetic field dips down to the ground at the North polar cusp. By placing the twin TRACERS satellites in a Sun-synchronous orbit, they always pass through Earth’s dayside polar cusp, studying thousands of reconnection events at these concentrated areas.
This will build a step-by-step picture of how magnetic reconnection changes over time and from Earth’s dayside to its nightside.
NASA’s TRICE-2 mission also studied magnetic reconnection near Earth, but with a pair of sounding rockets launched into the northern polar cusp over the Norwegian Sea in 2018.
“The TRICE mission took great data. It took a snapshot of the Earth system in one state. It proved that these instruments could make this kind of measurement and achieve this kind of science,” said David Miles, TRACERS principal investigator at the University of Iowa. “But the system’s more complicated than that. The TRACERS mission demonstrates how you can use multi-spacecraft technology to get a picture of how things are moving and evolving.”

Since previous missions could only take one measurement of an event per launch, too many changes in the region prevented forming a full picture. Following each other closely in orbit, the twin TRACERS satellites will provide multiple snapshots of the same area in rapid succession, spaced as closely as 10 seconds apart from each other, reaching a record-breaking 3,000 measurements in one year. These snapshots will build a picture of how the whole Earth system behaves in reaction to space weather, allowing scientists to better understand how to predict space weather in the magnetosphere.
Working Across Missions in Solar Harmony
The TRACERS mission will collaborate with other NASA heliophysics missions, which are strategically placed near Earth and across the solar system. At the Sun, NASA’s Parker Solar Probe closely observes our closest star, including magnetic reconnection there and its role in heating and accelerating the solar wind that drives the reconnection events investigated by TRACERS.
Data from recently launched NASA missions, EZIE (Electrojet Zeeman Imaging Explorer), studying electrical currents at Earth’s nightside, and PUNCH (Polarimeter to Unify the Corona and Heliosphere) studying the solar wind and interactions in Earth’s atmosphere, can be combined with observations from TRACERS. With research from these missions, scientists will be able to get a more complete understanding of how and when Earth’s protective magnetic shield can suddenly connect with solar wind, allowing the Sun’s material into Earth’s system.
“The TRACERS mission will be an important addition to NASA’s heliophysics fleet.” said Reinhard Friedel, TRACERS program scientist at NASA Headquarters in Washington. “The missions in the fleet working together increase understanding of our closest star to improve our ability to understand, predict, and prepare for space weather impacts on humans and technology in space.”
The TRACERS mission is led by David Miles at the University of Iowa with support from the Southwest Research Institute in San Antonio, Texas. NASA’s Heliophysics Explorers Program Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the mission for the agency’s Heliophysics Division at NASA Headquarters in Washington. The University of Iowa, Southwest Research Institute, University of California, Los Angeles, and the University of California, Berkeley, all lead instruments on TRACERS that study changes in the magnetic field and electric field. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR (Venture-class Acquisition of Dedicated and Rideshare) contract.

An artist’s concept of the Starlab commercial space station.Starlab As NASA continues its transition toward a commercial low Earth orbit marketplace, an agency-supported commercial space station, Starlab, recently completed five development and design milestones. Starlab’s planned design consists of a service module and a habitat that will be launched to orbit on a single flight.
The milestones, part of a NASA Space Act Agreement awarded in 2021, focused on reviews of Starlab’s preliminary design and safety, as well as spacecraft mockup and procurement plans. Each milestone provides NASA insight into the company’s development progress.
“As we work toward the future of low Earth orbit, these milestones demonstrate Starlab’s dedication to building a commercial space station that can support human life and advance scientific research,” said Angela Hart, program manager for NASA’s Commercial Low Earth Orbit Development Program at the agency’s Johnson Space Center in Houston. “Both the insight shared by Starlab and the expertise shared by NASA are critical to future mission success.”
Starlab recently completed a preliminary design and safety review of its station’s architecture and systems. The company now will begin detailed design and hardware development, culminating in a critical design review later this year. Critical design reviews are an important step in a station’s development, assessing design maturity before proceeding with fabrication and assembly.
An artist’s concept of the Starlab commercial space station.Starlab Starlab also has begun construction of a full-scale, high-fidelity mockup of the station. The mockup, which will be housed in the Space Vehicle Mockup Facility at NASA Johnson, will be used for human-in-the-loop testing, during which participants perform day-in-the-life walkthroughs and evaluate the interior design, crew training, procedure development, hardware checks, and in-flight issue resolution.
In addition, Starlab completed reviews of the system design architecture, procurement plan, and Northrop Grumman Cygnus spacecraft docking system design. In 2023, Northrop Grumman teamed up with Starlab to provide cargo logistics services and engineering consultation to support the commercial space station. These reviews included design configuration updates of solar arrays, docking ports, crew quarters, and more.
NASA supports the design and development of multiple commercial space stations through funded and unfunded agreements. Following the design and development phase, NASA plans to procure services from one or more companies as part of its strategy to become one of many customers for low Earth orbit stations.
