A SpaceX Falcon 9, launched from California, will ferry dozens of buyer satellites from all over the world right into a Solar-synchronous Earth orbit shortly after midnight native time on Tuesday.
The Transporter-17 mission, with 81 payloads aboard, is a part of the corporate’s Smallsat Rideshare Program, which additionally contains the mid-inclination Bandwagon missions in addition to the dawn-dusk Solar-synchronous orbit Twilight flight.
Liftoff from House Launch Advanced 4 East at Vandenberg House Pressure Station is scheduled throughout a launch window that opens at 12:10 a.m. PDT (0310 EDT / 0710 UTC).
Spaceflight Now can have reside protection starting about half-hour previous to liftoff.
SpaceX will launch the mission utilizing the Falcon 9 first stage booster B1097, which is its eleventh flight after launching Twilight, NROL-172, and Sentinel-6B and 7 Starlink missions.
Almost 8.5 minutes into the flight, B1097 will make a touchdown on the drone ship, ‘Of Course I Nonetheless Love You’, positioned out within the Pacific Ocean. If all goes effectively, this would be the 208th touchdown on this vessel and the 634th booster touchdown for SpaceX up to now.
Following a four-second trajectory correction burn about 51 minutes after liftoff, the primary deployment sequence will start. The Osiris-A payload, one in all twelve satellites manifested by California-based Maverick House System, kicks off the primary deployment sequence.
All however one satellite tv for pc will likely be launched throughout that roughly 10-minute deployment interval. SpaceX will reignite its Falcon 9 higher stage engine two extra time earlier than it deploys the ultimate satellite tv for pc, South Korea’s Earth statement satellite tv for pc, referred to as CAS500-4, roughly 2.5 hours after liftoff.
What’s onboard?
The Transporter-17 mission continues SpaceX’s mannequin of launching dozens of satellites from firms all over the world. As soon as once more, the vast majority of the payloads hitching a experience on this Falcon 9 rocket have been manifested by Exolaunch, which has positioned satellites on each Transporter mission going again to the beginning of the Smallsat Rideshare Program in 2020.
On this flight, Exolaunch is liable for 49 out of the 81 satellites, representing 20 worldwide prospects.
Among the many Exolaunch-back payloads are three of Muon House’s FireSat satellites, designed for the nonprofit Earth Hearth Alliance. They construct upon the prototype satellite tv for pc launched in March 2025, which helps to detect wildfires from orbit.
The Earth Hearth Alliance said on its web site that it goals for a constellation of greater than 20 satellites in low Earth orbit between 2027 and 2029, permitting it to have a roughly one hour revisit charge on wildfires with a capability to detect fires as small as 5 by 5 meters. It goals to finally have greater than 50 satellites in orbit.
“This story is about residing with fireplace: studying from it, adapting to it, harnessing it, and constructing resilience round it,” the nonprofit wrote in a LinkedIn publish. “Impressed by a species of fowl that has advanced alongside fireplace, our Black Kite Trio (BK-3) mission displays Earth Hearth Alliance’s imaginative and prescient of serving to individuals, ecosystems, and communities confidently coexist with fireplace.”
Different Exolaunch-manifested payloads embody 4 of Iceye’s artificial aperture radar satellites, Bro-31, the primary of Unseenlabs’ second-generation satellites designed for space-based radio detection; and Leonav-1, the United Arab Emirates first low Earth orbit PNT (place, navigation, and timing) satellite tv for pc.
One other firm liable for a number of payloads is Maverick House Programs. Amongst its manifested payloads are a pair from the Taiwanese Nationwide Central College. These are SCION-X (Scintillation and Ionosphere Prolonged), which can examine the ionosphere and higher ambiance, and KOYO (Kinetic Optical Yaw Observer), which can take a look at a fiber optic gyroscope.
Seops House additionally has 10 payloads it manifested for patrons throughout 5 nations. These embody GRITSS (Geodetic Reference Instrument Transponder for Small Satellites), a CubeSat from ISISPACE (Innovated Options in House) with assist from UMass Lowell and NASA, and SPEAR-1 (House Energy and Power Superior Recon), a satellite tv for pc developed by NearSpace Launch beneath a contract from the Naval Analysis Laboratory and the Division of Protection.
“The mission is a part of a three-spacecraft constellation constructed utilizing NearSpace Launch’s ThinSat® structure, a platform designed to offer a fast and cost-effective path for testing new applied sciences in orbit,” Seops stated in a prelaunch launch. “By elevating the Know-how Readiness Stage of crucial methods, missions like SPEAR assist guarantee promising improvements can transfer extra rapidly from analysis into operational use.”
Polish-German manufacturing firm, Orbital Matter, will even fly its Replicator-2 satellite tv for pc on this mission. It focuses on the potential of 3D printing supplies within the vacuum of area.
“It has 4 of our Printer Assisted Deployment Programs (P.A.D.S) onboard, 2 of which will likely be used to deploy our customized in-house designed foldable photo voltaic array. The opposite two will likely be standalone printers, one in all which is deploying a secret antenna payload,” wrote Robert Ihnatisin, Orbital Matter CEO, on LinkedIn.
“The purpose for this mission is to not solely present that 3D printing is feasible immediately within the harsh area atmosphere but additionally to point out that it may be used for deployment proper now! That is the most recent in a string of missions centered on advancing our printing expertise, with every mission getting us nearer to the goal of enormous scale and low cost solar energy in orbit.”
