At Lagrange points, the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them. These points in space can be used by spacecraft to reduce fuel consumption needed to remain in position.Of the five Lagrange points, three are unstable and two are stable. The unstable Lagrange points - labeled L1, L2 and L3 - lie along the line connecting the two large masses. The stable Lagrange points - labeled L4 and L5 - form the apex of two equilateral triangles that have the large masses at their vertices. L4 leads the orbit of earth and L5 follows.The L1 point of the Earth-Sun system affords an uninterrupted view of the Sun and will be home to three new heliophysics missions in 2025 - NASA's Interstellar Mapping and Acceleration Probe (IMAP), NASA's Carruthers Geocorona Observatory, and NOAA's Space Weather Follow On-Lagrange 1 (SWFO-L1). || ", "release_date": "2025-07-22T17:00:00-04:00", "update_date": "2025-07-22T17:09:38.635832-04:00", "main_image": { "id": 1157200, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a014800/a014873/14873_LagrangePoint1_H264.00001_print.jpg", "filename": "14873_LagrangePoint1_H264.00001_print.jpg", "media_type": "Image", "alt_text": "Credit: NASA's Conceptual Image Lab/Krystofer Kim", "width": 1024, "height": 561, "pixels": 574464 } }, { "id": 5567, "url": "https://svs.gsfc.nasa.gov/5567/", "page_type": "Visualization", "title": "New Missions to L1", "description": "Three missions, Carruthers, IMAP and SWFO-L1 will be launched to the Sun-Earth Lagrange Point, L1.", "release_date": "2025-07-21T18:59:59-04:00", "update_date": "2025-07-11T10:20:17.384003-04:00", "main_image": { "id": 1156845, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a005500/a005567/Geospace2025.New2L1.GSE.RE.clockSlate_CRTT.HD1080.00900.jpg", "filename": "Geospace2025.New2L1.GSE.RE.clockSlate_CRTT.HD1080.00900.jpg", "media_type": "Image", "alt_text": "A visualization depicting 3 missions: SWFO, IMAP, and Carruthers' orbits.
