NASA’s IMAP Mission to Study Boundaries of Our Home in SpaceSummary
- NASA’s new Interstellar Mapping and Acceleration Probe, or IMAP, will launch no earlier than Tuesday, Sept. 23 to study the heliosphere, a giant shield created by the Sun.
- The mission will chart the heliosphere’s boundaries to help us better understand the protection it offers life on Earth and how it changes with the Sun’s activity.
- The IMAP mission will also provide near real-time measurements of the solar wind, data that can be used to improve models predicting the impacts of space weather ranging from power-line disruptions to loss of satellites, to the health of voyaging astronauts.
Space is a dangerous place — one that NASA continues to explore for the benefit of all. It’s filled with radiation and high-energy particles that can damage DNA and circuit boards alike. Yet life endures in our solar system in part because of the heliosphere, a giant bubble created by the Sun that extends far beyond Neptune’s orbit.
With NASA’s new Interstellar Mapping and Acceleration Probe, or IMAP, launching no earlier than Tuesday, Sept. 23, humanity is set to get a better look at the heliosphere than ever before. The mission will chart the boundaries of the heliosphere to help us better understand the protection it offers and how it changes with the Sun’s activity. The IMAP mission will also provide near real-time measurements of space weather conditions essential for the Artemis campaign and deep space travel.
“With IMAP, we’ll push forward the boundaries of knowledge and understanding of our place not only in the solar system, but our place in the galaxy as a whole,” said Patrick Koehn, IMAP program scientist at NASA Headquarters in Washington. “As humanity expands and explores beyond Earth, missions like IMAP will add new pieces of the space weather puzzle that fills the space between Parker Solar Probe at the Sun and the Voyagers beyond the heliopause.”

Domain of SunThe heliosphere is created by the constant outflow of material and magnetic fields from the Sun called the solar wind. As the solar system moves through the Milky Way, the solar wind’s interaction with interstellar material carves out the bubble of the heliosphere. Studying the heliosphere helps scientists understand our home in space and how it came to be habitable.
As a modern-day celestial cartographer, IMAP will map the boundary of our heliosphere and study how the heliosphere interacts with the local galactic neighborhood beyond. It will chart the vast range of particles, dust, ultraviolet light, and magnetic fields in interplanetary space, to investigate the energization of charged particles from the Sun and their interaction with interstellar space.
The IMAP mission builds on NASA’s Voyager and IBEX (Interstellar Boundary Explorer) missions. In 2012 and 2018, the twin Voyager spacecraft became the first human-made objects to cross the heliosphere’s boundary and send back measurements from interstellar space. It gave scientists a snapshot of what the boundary looked like and where it was in two specific locations. While IBEX has been mapping the heliosphere, it has left many questions unanswered. With 30 times higher resolution and faster imaging, IMAP will help fill in the unknowns about the heliosphere.
Energetic neutral atoms: atomic messengers from our heliosphere’s edgeOf IMAP’s 10 instruments, three will investigate the boundaries of the heliosphere by collecting energetic neutral atoms, or ENAs. Many ENAs originate as positively charged particles released by the Sun but after racing across the solar system, these particles run into particles in interstellar space. In this collision, some of those positively charged particles become neutral, and an energetic neutral atom is born. The interaction also redirects the new ENAs, and some ricochet back toward the Sun.
Charged particles are forced to follow magnetic field lines, but ENAs travel in a straight line, unaffected by the twists, turns, and turbulences in the magnetic fields that permeate space and shape the boundary of the heliosphere. This means scientists can track where these atomic messengers came from and study distant regions of space from afar. The IMAP mission will use the ENAs it collects near Earth to trace back their origins and construct maps of the boundaries of the heliosphere, which would otherwise be invisible from such a distance.
“With its comprehensive state-of-the-art suite of instruments, IMAP will advance our understanding of two fundamental questions of how particles are energized and transported throughout the heliosphere and how the heliosphere itself interacts with our galaxy,” said Shri Kanekal, IMAP mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

The IMAP mission will also support near real-time observations of the solar wind and energetic solar particles, which can produce hazardous conditions in the space environment near Earth. From its location at Lagrange Point 1, about 1 million miles from Earth toward the Sun, IMAP will provide around a half hour’s warning of dangerous particles headed toward our planet. The mission’s data will help with the development of models that can predict the impacts of space weather ranging from power-line disruptions to loss of satellites.
“The IMAP mission will provide very important information for deep space travel, where astronauts will be directly exposed to the dangers of the solar wind,” said David McComas, IMAP principal investigator at Princeton University.
Cosmic dust: hints of the galaxy beyondIn addition to measuring ENAs and solar wind particles, IMAP will also make direct measurements of interstellar dust — clumps of particles originating outside of the solar system that are smaller than a grain of sand. This space dust is largely composed of rocky or carbon-rich grains leftover from the aftermath of supernova explosions.
The specific elemental composition of this space dust is a postmark for where it comes from in the galaxy. Studying cosmic dust can provide insight into the compositions of stars from far outside our solar system. It will also help scientists significantly advance what we know about these basic cosmic building materials and provide information on what the material between stars is made of.
David McComas leads the mission with an international team of 27 partner institutions. APL is managing the development phase and building the spacecraft, and it will operate the mission. IMAP is the fifth mission in NASA’s Solar Terrestrial Probes Program portfolio. The Explorers and Heliophysics Projects Division at NASA Goddard manages the STP Program for the agency’s Heliophysics Division of NASA’s Science Mission Directorate. NASA’s Launch Services Program, based at NASA’s Kennedy Space Center in Florida, manages the launch service for the mission.

XRISM uncovers a mystery in the cosmic winds of change
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching from a disc around a neutron star and those from material circling supermassive black holes. The surprisingly dense wind blowing from the stellar system challenges our understanding of how such winds form and drive change in their surroundings.

Ancient Floods and Rolling Rocks Boosts the Hunt for Life on Mars
David Bowie once sung ‘Is there life on Mars?’ and along with being a question in a hit song, its also a question that has driven decades of missions to the red planet. From early orbital surveys to rovers hunting for evidence that life once existed beyond Earth the search has become more and more sophisticated. Europe's upcoming Mars rover mission is one such mission and it has received an unexpected boost in its search for signs of ancient life, as two new studies reveal that natural Martian processes could deliver rich organic materials directly to the rover, eliminating the need for long distance travel to find the building blocks of life.
A Spacecraft Could Explore 3I/ATLAS to Learn More About "Cosmic Noon"
An examination of the interstellar object 3I/ATLAS shows that it is likely to be a remnant of the Galaxy's “Cosmic Noon” period, ca. 9 to 13 billion years ago. An examination of the object by an active mission could provide clues about stellar and planetary formation, and maybe the emergence of life, during this early period of galactic history.

NASA, Partners Push Forward with Remotely Piloted Airspace Integration
NASA and its partners recently tested a tool for remotely piloted operations that could enable operators to transport people and goods more efficiently within urban areas.
The team’s goal is to ensure that when these remotely piloted aircraft – including electric vertical takeoff and landing vehicles (eVTOLs) – take to the skies, air traffic controllers won’t be overburdened by increased flight operations and safety is maintained across the national airspace.
On Aug. 21, NASA’s Air Traffic Management eXploration Project (ATM-X) assisted Wisk Aero when they flew a Bell 206 helicopter in Hollister, California. The purpose of the flight test was to evaluate and fine-tune a ground-based radar developed by Collins Aerospace. The radar, which provides aircraft location data, could be used during future remotely piloted operations to detect and avoid other aircraft in the vicinity. NASA, Wisk, and Collins researchers also used the flight to test data exchange capabilities across different geographic locations between the groups, a critical capability for future remotely piloted operators in a shared airspace. This work builds on a November 2024 flight test NASA performed with Reliable Robotics and Collins Aerospace.
Initial analysis of the August testing of Collins’ ground-based radar actively and accurately surveilled the airspace during the aircraft’s flight test. The Collins radar system also successfully transmitted these data to NASA’s Mission Visualization Research Command Center lab at NASA’s Ames Research Center in California’s Silicon Valley. NASA, Wisk, and Collins will further analyze the flight data to better understand the radar’s performance and data exchange capabilities for future remotely piloted flight tests. This testing is a part of ATM-X’s remotely piloted testing campaign, designed to identify the infrastructure and technologies needed for the Federal Aviation Administration to safely integrate drones and air taxis into the airspace, bringing the movement of people and goods off the ground, and into the sky.
Remotely piloted eVTOL aircraft could bridge the gap for urban communities by offering a more affordable and accessible method of transportation and delivery services in congested, highly-populated areas.
NASA and Wisk will continue to collaborate on emerging eVTOL technologies to safely integrate advanced aircraft, into the national airspace. Together, the teams will gather data on eVTOL performance and characteristics during a flight test of a helicopter, which will act as a “surrogate” simulating an eVTOL flight. This work will mark another critical step towards better connecting communities across the globe.
