NASA’s IMAP (Interstellar Mapping and Acceleration Probe) mission will map the boundaries of the heliosphere, the bubble created by the solar wind that protects our solar system from cosmic radiation. Credit: NASA/Princeton/Patrick McPike NASA will hold a media teleconference at 12 p.m. EDT on Thursday, Sept. 4, to discuss the agency’s upcoming Sun and space weather missions, IMAP (Interstellar Mapping and Acceleration Probe) and Carruthers Geocorona Observatory. The two missions are targeting launch on the same rocket no earlier than Tuesday, Sept. 23.
The IMAP mission will map the boundaries of our heliosphere, the vast bubble created by the Sun’s wind that encapsulates our entire solar system. As a modern-day celestial cartographer, IMAP will explore how the heliosphere interacts with interstellar space, as well as chart the range of particles that fill the space between the planets. The IMAP mission also will support near real-time observations of the solar wind and energetic particles. These energetic particles can produce hazardous space weather that can impact spacecraft and other NASA hardware as the agency explores deeper into space, including at the Moon under the Artemis campaign.
NASA’s Carruthers Geocorona Observatory will image the ultraviolet glow of Earth’s exosphere, the outermost region of our planet’s atmosphere. This data will help scientists understand how space weather from the Sun shapes the exosphere and ultimately impacts our planet. The first observation of this glow – called the geocorona – was captured during Apollo 16, when a telescope designed and built by George Carruthers was deployed on the Moon.
Audio of the teleconference will stream live on the agency’s website at:

Participants include:
Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington Teresa Nieves-Chinchilla, director, Moon to Mars Space Weather Analysis Office, NASA’s Goddard Space Flight Center in Greenbelt, Maryland David J. McComas, IMAP principal investigator, Princeton University Lara Waldrop, Carruthers Geocorona Observatory principal investigator, University of Illinois Urbana-Champaign To participate in the media teleconference, media must RSVP no later than 11 a.m. on Sept. 4 to Sarah Frazier at: sarah.frazier@nasa.gov. NASA’s media accreditation policy is available online.
The IMAP and Carruthers Geocorona Observatory missions will launch on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Also launching on this flight will be the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On – Lagrange 1 (SWFO-L1), which will monitor solar wind disturbances and detect and track coronal mass ejections before they reach Earth.
David McComas, professor, Princeton University, leads the IMAP mission with an international team of 27 partner institutions. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built the spacecraft and will operate the mission. NASA’s IMAP is the fifth mission in NASA’s Solar Terrestrial Probes Program portfolio.
The Carruthers Geocorona Observatory mission is led by Lara Waldrop from the University of Illinois Urbana-Champaign. Mission implementation is led by the Space Sciences Laboratory at University of California, Berkeley, which also designed and built the two ultraviolet imagers. BAE Systems designed and built the Carruthers spacecraft.
The Solar Terrestrial Probes Program Office, part of the Explorers and Heliophysics Project Division at NASA Goddard, manages the IMAP and Carruthers Geocorona Observatory missions for NASA’s Science Mission Directorate.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
These maps of Prince George’s County, MD, show surface temperatures collected a few hours apart on July 30, 2023 from the Landsat 9 satellite and the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument. The dark blue spots in the right hand image are likely clouds that formed in the afternoon.Credit: Stephanie Schollaert Uz, NASA Goddard Space Flight Center Thousands of Americans are impacted each summer by excessive heat and humidity, some suffering from heat-related illnesses when the body can’t cool itself down. Data from NASA satellites could help local governments reduce the sweltering risks, thanks to a collaboration between NASA scientists and officials in Prince George’s County, Maryland. The effort demonstrates how local officials in other communities could turn to NASA data to inform decisions that provide residents with relief from summer heat.
NASA researchers and their Prince George’s County collaborators reported in Frontiers in Environmental Science that they used the Landsat 8 satellite, jointly operated by NASA and the US Geological Survey, and NASA’s Aqua satellite, to gain insight into surface temperature trends across the county over the past few decades. The data also show how temperatures have responded to changing land use and construction. It is information that county planners and environmental experts hope can aid them in their attempts to remediate and prevent heat dangers in the future. The collaboration may also help the county’s first responders anticipate and prepare for heat-related emergencies and injuries.
Cooperation with Prince George’s County expands on NASA’s historic role, said Stephanie Schollaert Uz, an applications scientist with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and one of the study authors. “Applying government satellite data to county-level problems is new here. We’re trying to make it easier for people outside of NASA to use our data, in part by including how-to guides referenced at the end of our paper,” Schollaert Uz said.
In the long run, county officials hope to use NASA satellites to track the negative health impacts that arise from land use and modification. Removal of tree cover and the construction of non-permeable roads, parking lots, and structures that lead to water runoff are among the factors that create heat islands, where temperatures in localized areas soar relative to the surrounding landscape. In addition to the direct dangers of heat for county residents and workers, areas with higher-than-normal temperatures can drive intense local weather events.
“There’s potentially a greater incidence of microbursts,” said Mary Abe of Prince George’s County’s sustainability division. “The atmosphere can become supercharged over hot spots,” causing high winds and flood-inducing rains.
Prince George’s County planners anticipate relying on NASA satellites to determine where residents and county employees are at greater risk, predict how future construction could impact heat dangers, and develop strategies to moderate heat in areas currently experiencing elevated summer temperatures. Efforts might include protecting existing trees and planting new ones. It could include replacing impermeable surfaces (cement, pavement, etc.) with alternatives that let water soak into the ground rather than running off into storm drains. To verify and calibrate the satellite observations crucial for such planning, county experts are considering enlisting residents to act as citizen scientists to collect temperature and weather data on the ground, Abe said.
Eventually, the NASA satellite temperature data could also lead to strategies to curb insect-borne diseases, said Evelyn Hoban, associate director for the Prince George’s County division of environmental health and communicable disease. “Once we know where the higher temperatures are, we can check to see if they create mosquito or tick breeding grounds,” said Hoban, who coauthored the study. “We could then focus our outreach and education, and perhaps prevention efforts, on areas of greater heat and risk.”
A NASA guide is available to aid other communities who hope to duplicate the Prince George’s County study. The guide provides introductions on a variety of NASA satellite and ground-based weather station data. Instructions for downloading and analyzing the data are illustrated in an accompanying tutorial that uses the Prince George’s County study as an example for other communities to follow on their own.
One of the greatest benefits of the collaboration, Abe said, is the boost in credibility that comes from incorporating NASA resources and expertise in the county’s efforts to improve safety and health. “It’s partly the NASA brand. People recognize it and they’re really intrigued by it,” she said. “Working with NASA builds confidence that the decision-making process is based firmly in science.”

NASA’s IMAP will use 10 science instruments to study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system from radiation incoming from interstellar space. This mission and its two rideshares will orbit the Sun near Lagrange point 1, about one million miles from Earth, where it will scan the heliosphere, analyze the composition of charged particles, and investigate how those particles move through the solar system. This will provide information on how the Sun accelerates charged particles, filling in essential puzzle pieces to understand the space weather environment across the solar system. The IMAP spacecraft also will continuously monitor solar wind and cosmic radiation. Scientists can use this information to evaluate new and improved capabilities for space weather prediction tools and models, which are vital for the health of human space explorers and the longevity of technological systems, like satellites and power grids, that can affect life on Earth.
The agency’s Carruthers Geocorona Observatory is a small satellite set to study the exosphere, the outermost part of Earth’s atmosphere. Using ultraviolet cameras, it will monitor how space weather from the Sun impacts the exosphere, which plays a crucial role in protecting Earth from space weather events that can affect satellites, communications, and power lines. The exosphere, a cloud of neutral hydrogen extending to the Moon and possibly beyond, is created by the breakdown of water and methane by ultraviolet light from the Sun, and its glow, known as the geocorona, has been observed globally only four times before this mission.
The SWFO-L1 mission, managed by NOAA and developed with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and commercial partners, will use a suite of instruments to provide real-time measurements of solar wind, along with a compact coronagraph to detect coronal mass ejections from the Sun. The observatory, serving as an early warning beacon for potentially destructive space weather events, will enable faster and more accurate forecasts. Its 24/7 data will support NOAA’s Space Weather Prediction Center in protecting vital infrastructure, economic interests, and national security, both on Earth and in space.
David McComas, professor, Princeton University, leads the IMAP mission with an international team of 25 partner institutions. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built the spacecraft and operates the mission. NASA’s IMAP is the fifth mission in NASA’s Solar Terrestrial Probes program portfolio.
