It\u2019s 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\u2019s orbit.<\/p>\n<p>With NASA\u2019s 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\u2019s activity. The IMAP mission will also provide near real-time measurements of space weather conditions essential for the Artemis campaign and deep space travel.\u00a0<\/p>\n<p>\u201cWith IMAP, we\u2019ll 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,\u201d said Patrick Koehn, IMAP program scientist at NASA Headquarters in Washington. \u201cAs 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.\u201d<\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\">\n<p>\n<iframe loading=\"lazy\" title=\"Mapping the Boundaries of Our Home in Space with NASA\u2019s IMAP Mission\" width=\"1170\" height=\"658\" src=\"https:\/\/www.youtube.com\/embed\/gEOraINOI5c?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/p>\n<\/figure>\n<p><em><a target=\"_blank\" href=\"https:\/\/svs.gsfc.nasa.gov\/14895\/\" data-type=\"link\" data-id=\"https:\/\/svs.gsfc.nasa.gov\/14895\/\">Download<\/a> this video from NASA&#8217;s Scientific Visualization Studio.<\/em><\/p>\n<p>The 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\u2019s 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.<\/p>\n<p>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.<\/p>\n<p>The IMAP mission builds on NASA\u2019s <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/voyager\/\">Voyager<\/a> and <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/mission\/ibex\/\">IBEX<\/a> (Interstellar Boundary Explorer) missions. In 2012 and 2018, the twin Voyager spacecraft became the first human-made objects to cross the heliosphere\u2019s 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.<\/p>\n<p>Of IMAP\u2019s 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.<\/p>\n<p>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.<\/p>\n<p>\u201cWith 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,\u201d said Shri Kanekal, IMAP mission scientist at NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland.<\/p>\n<p>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.\u00a0From its location at Lagrange Point 1, about 1 million miles from Earth toward the Sun, IMAP will provide around a half hour\u2019s warning of dangerous particles headed toward our planet. The mission\u2019s 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.<\/p>\n<p>\u201cThe IMAP mission will provide very important information for deep space travel, where astronauts will be directly exposed to the dangers of the solar wind,\u201d said David McComas, IMAP principal investigator at Princeton University.<\/p>\n<p>In addition to measuring ENAs and solar wind particles, IMAP will also make direct measurements of interstellar dust \u2014 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.\u00a0<\/p>\n<p>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.<\/p>\n<p>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\u2019s Solar Terrestrial Probes Program portfolio. The Explorers and Heliophysics Projects Division at NASA Goddard manages the STP Program for the agency\u2019s Heliophysics Division of NASA\u2019s Science Mission Directorate. NASA\u2019s Launch Services Program, based at NASA\u2019s Kennedy Space Center in Florida, manages the launch service for the mission.<\/p>\n<p><em><strong>By <a target=\"_blank\" href=\"https:\/\/science.nasa.gov\/missions\/nasas-imap-mission-to-study-boundaries-of-our-home-in-space\/mailto:mjohnson-groh@rothe.com\">Mara Johnson-Groh<\/a><\/strong><br \/><strong>NASA\u2019s Goddard Space Flight Center, Greenbelt, Md.<\/strong><\/em><\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/science.nasa.gov\/missions\/nasas-imap-mission-to-study-boundaries-of-our-home-in-space\/?rand=6349\" target=\"_blank\">Source link <\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Summary NASA\u2019s 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.
