The winged spacecraft, flying under the mission names USSF-36 and Orbital Test Vehicle 8 (OTV-8), will launch atop a Falcon 9 rocket from pad 39A at NASA\u2019s Kennedy Space Center at 11:50 p.m. EDT (0350 UTC).<\/p>\n<p>The X-37B will be operated by the Fifth Space Operations Squadron, part of USSF Delta 9, alongside the U.S. Air Force Rapid Capabilities Office (USAF RCO).<\/p>\n<p>Spaceflight Now will have live coverage beginning about an hour prior to liftoff.<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/LxaypgtnfGY\" width=\"678\" height=\"381\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>Meteorologists with the 45th Weather Squadron forecast a 65 percent chance for favorable conditions for liftoff at the opening launch window Thursday night. Conditions improve to 80 percent favorable as the window progresses.<\/p>\n<p>They\u2019re primarily watching for impacts from Hurricane Erin as it continues to move alongside the East Coast of the United States.<\/p>\n<p>\u201cThe very large Hurricane Erin will continue moving north and eventually northeast off the eastern coast of the US and out into the open Atlantic through the remainder of the week,\u201d launch weather officers wrote. \u201cAs it does so, it will leave behind a trailing trough and deeper moisture that will merge with a boundary dropping into the southeastern US. Prevailing flow will shift out of the west into Thursday, which will lead to the best coverage of afternoon and evening storms favoring the east side of the state including the Spaceport.\u201d<\/p>\n<p>SpaceX will use the Falcon 9 first stage booster with the tail number B1092, which will launch for a sixth time. Its previous missions include CRS-32, GPS III-7 SV 08 and NROL-69.<\/p>\n<p>A little more than 8.5 minutes after liftoff, B1092 will aim for a landing at Landing Zone 2 (LZ-2) at Cape Canaveral Space Force Station. If successful, this will be the 13th touchdown at LZ-2 and the 490th booster landing to date.<\/p>\n<p>The X-37B was encapsulated inside Falcon payload fairing on Aug. 14 and then transported to LC-39A for integration with the rest of the Falcon 9 rocket. The full stack rolled out to the pad Wednesday morning.<\/p>\n<p>This is the third time that a Falcon rocket will launch one of these spaceplanes. SpaceX launched the OTV-5 mission on its Falcon 9 rocket and OTV-7 using its Falcon Heavy. The other X-37B missions were lofted by United Launch Alliance\u2019s Atlas 5 rocket.<\/p>\n<p>The more powerful Falcon Heavy was needed for the last X-37B mission in order to send the vehicle into a highly elliptical, high Earth orbit.<\/p>\n<figure id=\"attachment_70585\" aria-describedby=\"caption-attachment-70585\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-70585\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/08\/20250820_USSF-36_mission_patch.png\" alt=\"\" width=\"876\" height=\"876\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/08\/20250820_USSF-36_mission_patch.png 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/08\/20250820_USSF-36_mission_patch-300x300.png 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/08\/20250820_USSF-36_mission_patch-150x150.png 150w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/08\/20250820_USSF-36_mission_patch-768x768.png 768w\" sizes=\"(max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-70585\" class=\"wp-caption-text\">An artist\u2019s rending of the USSF-36 mission patch.

The longest continuous mission was OTV-6, which lasted nearly 909 days.<\/p>\n<p>Michelle Parker, vice president of Boeing Space Mission Systems said the company incorporated improvements into its two reusable X-37B spaceplanes since the first flight in 2010. The first of the two will fly the OTV-8 mission.<\/p>\n<p>\u201cOver the course of our missions, we\u2019ve flown several generations of batteries and solar cells that have significantly improved our power generation capability,\u201d said Parker. \u201cWe\u2019ve enhanced the thermal protection tiles to improve maximum temperature capability, manufacturability, and reusability.<\/p>\n<p>\u201cMission 7 broke new ground with fault protection, autonomy, and collision avoidance.&nbsp; Autonomy is going to be critical as space becomes more congested and we operate the spaceplane in multiple orbital regimes.\u201d<\/p>\n<figure id=\"attachment_68897\" aria-describedby=\"caption-attachment-68897\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-68897\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_aerobraking_small.jpeg\" alt=\"\" width=\"876\" height=\"472\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_aerobraking_small.jpeg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_aerobraking_small-300x162.jpeg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_aerobraking_small-678x365.jpeg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_aerobraking_small-768x414.jpeg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-68897\" class=\"wp-caption-text\">Artist rendering of the X-37B conducting an aerobraking maneuver using the drag of Earth\u2019s atmosphere.

Chance Saltzman, the Chief of Space Operations for the U.S. Space Force.<\/p>\n<p>\u201cIn so doing, it will strengthen the resilience, reliability, adaptability and data transport speeds of our satellite communications architecture,\u201d Saltzman added.<\/p>\n<p>The OTV-8 flight will also feature what the Space Force calls \u201cthe world\u2019s highest performing quantum inertial sensor ever used in space.\u201d It will demonstrate navigational capabilities without the use of GPS by instead \u201cdetecting rotation and acceleration of atoms.\u201d<\/p>\n<p>\u201cOTV 8\u2019s quantum inertial sensor demonstration is a welcome step forward for operational resilience in space,\u201d said Col. Ramsey Horn, Space Delta 9 commander. \u201cWhether navigating beyond Earth based orbits in cislunar space or operating in GPS-denied environments, quantum inertial sensing allows for robust navigation capabilities when GPS navigation is not possible.\u201d<\/p>\n<p>It\u2019s unclear how long the X-37B will remain in space this time around. Only one mission so far lasted less than a year and that was the first flight, OTV-1, which took off Florida in April 2010 and landed in California in December of that year.<\/p>\n<figure id=\"attachment_68895\" aria-describedby=\"caption-attachment-68895\" style=\"width: 468px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-68895\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_obital.jpeg\" alt=\"\" width=\"468\" height=\"677\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_obital.jpeg 468w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2025\/03\/20250304_X-37B_obital-207x300.jpeg 207w\" sizes=\"auto, (max-width: 468px) 100vw, 468px\"><figcaption id=\"caption-attachment-68895\" class=\"wp-caption-text\">An X-37B onboard camera, used to ensure the health and safety of the vehicle, captures an image of Earth while conducting experiments in a highly elliptical orbit in 2024.
