            "description": "Three heliophysics missions will be launched to Lagrange Point 1 (L1) where they will get an uninterrupted view of the Sun about one million miles from Earth towards the Sun. The missions will launch no earlier than September 2025 on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.\r\n\r\n**IMAP**\r\nNASA's Interstellar Mapping and Acceleration Probe (IMAP) will study the heliosphere, the Sun’s magnetic bubble that shields our solar system, to better understand the protective boundary. To achieve this, IMAP will sample, analyze, and map particles streaming toward Earth from the edges of interstellar space. The mission also will help researchers learn more about the solar wind — the constant stream of particles from the Sun — energetic particles, and cosmic rays in the heliosphere. These particles can affect human explorers in space, harm technological systems, and likely play a role in the presence of life itself in the universe.\r\n\r\n**Carruthers Geocorona Observatory**\r\nNASA's Carruthers Geocorona Observatory will study Earth's geocorona, the part of the outer atmosphere that emits ultraviolet light. Studying this will allow researchers to better understand the atmosphere and improve our ability to predict how solar activity can affect Earth.\r\n\r\n**SWFO-L1**\r\nNOAA's Space Weather Follow On-Lagrange 1 (SWFO-L1) mission will keep a watchful eye on the Sun and near-Earth environment for space weather activity, using a suite of instruments to make real time measurements of the solar wind. The 24/7 data from SWFO-L1 will give operators critical lead time to take precautionary actions that protect vital infrastructure, economic interests and national security on Earth and in space.",

Early on the morning of Jan. 10, the team confirmed the spacecraft had successfully entered its final L1 orbit, where it will stay for the duration of its mission.From L1, IMAP will explore and map the very boundaries of our heliosphere — the protective bubble created by the solar wind that encapsulates our entire solar system — and study how the heliosphere interacts with the local galactic neighborhood beyond.Learn more about the milestone: https://science.nasa.gov/blogs/imap/2026/01/12/nasas-imap-mission-reaches-its-destination/ || ",

            "description": "In 1972, Apollo 16 astronauts placed an ultraviolet camera on the Moon that captured the first images of Earth’s geocorona, the light emitted by Earth’s outermost atmospheric layer. A new NASA mission bearing the name of the telescope’s creator, Dr. George R. Carruthers, will launch into space to build on that legacy. From a vantage point roughly one million miles closer to the Sun than Earth is, the Carruthers Geocorona Observatory will capture the most comprehensive views of the geocorona to date. The observations will reveal new insights into the structure of our atmosphere, how solar eruptions impact Earth, and how a planet’s surface water can escape to space, aiding the search for habitable planets elsewhere in the universe.Learn more about Carruthers Geocorona Observatory science: https://science.nasa.gov/science-research/heliophysics/new-nasa-mission-to-reveal-earths-invisible-haloLearn more about the Carruthers Geocorona Observatory: https://science.nasa.gov/mission/carruthers-geocorona-observatory/ || ",

Additionally, IMAP will support real-time observations of the solar wind and energetic particles, which can produce hazardous conditions in the space environment near Earth. The IMAP spacecraft is situated at the first Earth-Sun Lagrange point (L1), at around one million miles from Earth toward the Sun. There, it will collect and measure particles that have traveled from the Sun, the heliosphere’s boundary 6 to 9 billion miles away, and interstellar space. At L1, it can also provide about a half hour's warning to voyaging astronauts and spacecraft near Earth of harmful radiation coming their way. || ",

            "description": "NASA’s IMAP (Interstellar Mapping and Acceleration Probe) will explore and map the very boundaries of our heliosphere — a huge bubble created by the Sun's wind that encapsulates our entire solar system — and study how the heliosphere interacts with the local galactic neighborhood beyond.As a modern-day celestial cartographer, IMAP will also explore and chart the vast range of particles in interplanetary space, helping to investigate two of the most important overarching issues in heliophysics — the energization of charged particles from the Sun, and the interaction of the solar wind at its boundary with interstellar space. Additionally, IMAP will support real-time observations of the solar wind and energetic particles, which can produce hazardous conditions in the space environment near Earth. The IMAP spacecraft will be located at Lagrange Point 1, or L1. Lagrange points are positions in space where objects sent there tend to stay put. At L1, which is around 1 million miles from Earth towards the Sun, the gravitational pull of the Sun and Earth are balanced, allowing spacecraft to reduce fuel consumption needed to remain in position. At L1, IMAP will have a clear view of the heliosphere and will also be positioned to provide advanced warning of incoming solar storms headed to Earth.
