Preparations for Next Moonwalk Simulations Underway (and Underwater)
On Sept. 9, 2025, NASA’s Solar Dynamics Observatory captured this image of the Sun.NASA/GSFC/Solar Dynamics Observatory It looked like the Sun was heading toward a historic lull in activity. That trend flipped in 2008, according to new research.
The Sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case in point: Since the 1980s, the amount of solar activity had been steadily decreasing all the way up to 2008, when solar activity was the weakest on record. At that point, scientists expected the Sun to be entering a period of historically low activity.
But then the Sun reversed course and started to become increasingly active, as documented in the study, which appears in The Astrophysical Journal Letters. It’s a trend that researchers said could lead to an uptick in space weather events, such as solar storms, flares, and coronal mass ejections.
“All signs were pointing to the Sun going into a prolonged phase of low activity,” said Jamie Jasinski of NASA’s Jet Propulsion Laboratory in Southern California, lead author of the new study. “So it was a surprise to see that trend reversed. The Sun is slowly waking up.”
The earliest recorded tracking of solar activity began in the early 1600s, when astronomers, including Galileo, counted sunspots and documented their changes. Sunspots are cooler, darker regions on the Sun’s surface that are produced by a concentration of magnetic field lines. Areas with sunspots are often associated with higher solar activity, such as solar flares, which are intense bursts of radiation, and coronal mass ejections, which are huge bubbles of plasma that erupt from the Sun’s surface and streak across the solar system.
NASA scientists track these space weather events because they can affect spacecraft, astronauts’ safety, radio communications, GPS, and even power grids on Earth. Space weather predictions are critical for supporting the spacecraft and astronauts of NASA’s Artemis campaign, as understanding the space environment is a vital part of mitigating astronaut exposure to space radiation.
Launching no earlier than Sept. 23, NASA’s IMAP (Interstellar Mapping and Acceleration Probe) and Carruthers Geocorona Observatory missions, as well as the National Oceanic and Atmospheric Administration’s SWFO-L1 (Space Weather Follow On-Lagrange 1) mission, will provide new space weather research and observations that will help to drive future efforts at the Moon, Mars, and beyond.
Solar activity affects the magnetic fields of planets throughout the solar system. As the solar wind — a stream of charged particles flowing from the Sun — and other solar activity increase, the Sun’s influence expands and compresses magnetospheres, which serve as protective bubbles of planets with magnetic cores and magnetic fields, including Earth. These protective bubbles are important for shielding planets from the jets of plasma that stream out from the Sun in the solar wind.
Over the centuries that people have been studying solar activity, the quietest times were a three-decade stretch from 1645 to 1715 and a four-decade stretch from 1790 to 1830. “We don’t really know why the Sun went through a 40-year minimum starting in 1790,” Jasinski said. “The longer-term trends are a lot less predictable and are something we don’t completely understand yet.”
In the two-and-a-half decades leading up to 2008, sunspots and the solar wind decreased so much that researchers expected the “deep solar minimum” of 2008 to mark the start of a new historic low-activity time in the Sun’s recent history.
“But then the trend of declining solar wind ended, and since then plasma and magnetic field parameters have steadily been increasing,” said Jasinski, who led the analysis of heliospheric data publicly available in a platform called OMNIWeb Plus, run by NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The data Jasinski and colleagues mined for the study came from a broad collection of NASA missions. Two primary sources — ACE (Advanced Composition Explorer) and the Wind mission — launched in the 1990s and have been providing data on solar activity like plasma and energetic particles flowing from the Sun toward Earth. The spacecraft belong to a fleet of NASA Heliophysics Division missions designed to study the Sun’s influence on space, Earth, and other planets.

Video: 00:01:43 An essential part of ESA’s Space Safety programme is dedicated to getting and keeping Earth’s orbits clean from space debris. In the long run, the Agency aspires to stimulate a true circular economy in space, minimising the impact of spaceflight on Earth and its resources where possible. As part of ESA’s Zero Debris approach, new ESA missions will be designed for safe operations and disposal to stop the creation of new debris by 2030.
ESA has now taken another important step on the road towards sustainability in space with its first in-orbit servicing mission RISE, planned for launch in 2029.
RISE is a commercial in-orbit servicing mission that will demonstrate that it can safely rendezvous and dock to a geostationary client satellite, extending the life of geostationary satellites that need support with attitude and orbit control, but are otherwise in working order.
After verifying that it meets all the performance standards in a first demonstration, prime contractor, operator and co-founder D-Orbit will start commercial life extension services for geostationary satellites.
ESA’s RISE mission marks a promising step towards enhancing in-orbit services and technologies, such as refuelling, refurbishment and assembling – all essential elements for creating a circular economy in space.

A SpaceX Falcon 9 rocket carrying Northrop Grumman’s Cygnus XL spacecraft is launched on NASA’s Northrop Grumman Commercial Resupply Services 23 mission to the International Space Station on Sunday, Sept. 14, 2025.Credit: NASA NASA is sending more science, technology demonstrations, and crew supplies to the International Space Station following the successful launch of the agency’s Northrop Grumman Commercial Resupply Services 23 mission, or Northrop Grumman CRS-23.
The company’s Cygnus XL spacecraft, carrying more than 11,000 pounds of cargo to the orbiting laboratory, lifted off at 6:11 p.m. EDT Sunday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This mission is the first flight of the larger, more cargo-capable version of the solar-powered spacecraft.
Cygnus XL is scheduled to be captured at 6:35 a.m. on Wednesday, Sept. 17, by the Canadarm2 robotic arm, which NASA astronaut Jonny Kim will operate with assistance from NASA astronaut Zena Cardman. Following capture, the spacecraft will be installed to the Unity module’s Earth-facing port for cargo unloading.
The resupply mission is carrying dozens of research experiments that will be conducted during Expedition 73, including materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. The spacecraft also will deliver a specialized UV light system to prevent the growth of microbe communities that form in water systems and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.
These are just a sample of the hundreds of scientific investigations conducted aboard the station in the areas of biology and biotechnology, Earth and space science, physical sciences, as well as technology development and demonstrations. For nearly 25 years, NASA has supported a continuous U.S. human presence aboard the orbiting laboratory, where astronauts have learned to live and work in space for extended periods of time. The space station is a springboard for developing a low Earth economy and NASA’s next great leaps in exploration, including Artemis missions to the Moon and American astronaut missions to Mars.
NASA’s arrival, capture, and installation coverage are as follows (all times Eastern and subject to change based on real-time operations):
Wednesday, Sept. 17
5 a.m. – Arrival coverage begins on NASA+, Amazon Prime, and more.
6:35 a.m. – Capture of Cygnus XL with the space station’s robotic arm.
8 a.m. – Installation coverage begins on NASA+, Amazon Prime, and more.
All coverage times are estimates and could be adjusted based on operations after launch. Follow the space station blog for the most up-to-date information.
Cygnus XL is scheduled to remain at the orbiting laboratory until March 2026, before it departs and disposes of several thousand pounds of trash through its re-entry into Earth’s atmosphere, where it will harmlessly burn up. The spacecraft is named the S.S. William “Willie” C. McCool, in honor of the NASA astronaut who perished in 2003 during the space shuttle Columbia accident.
