Acadia satellites also w ill be equipped with optical communications terminals\, a move designed to reduce the time from imagery collection to downlinking. Capella is planni ng a 30 satellite constellation in its final stage.\n\nWebcast: \nhttps:/ /www.rocketlabusa.com/live-stream LOCATION:LC-1B\, PVQ8+R3\, Māhia 4198\, Neuseeland END:VEVENT BEGIN:VEVENT SUMMARY:(NET) Falcon 9 B5 • Mission Possible DTSTART;VALUE=DATE:20250601 DTEND;VALUE=DATE:20250602 UID:253086962546 DESCRIPTION:A SpaceX Falcon 9 Block 5 rocket will launch the Mission Possi ble reentry capsule for the Exploration Company.

The satellites\, built by Boeing\, will provide internet services over most of the populated world\, building on SES’s O3b network.\n-\nBuilt b y Boeing the O3b mPower satellites are improved second generation satell ites for the SES owned O3b Networks. Each satellite features newly redesig ned power modules that address the previous electrical issues experienced by the first six O3b mPOWER satellites\, which will act as spares. The ~2 050kg second generation satellites are very high-throughput satellites\, m aking it a terabit-per-second constellation. The constellation will have 3 0000 fully-shapeable and steerable beams that can be shifted and switched in real time to align with customers’ quickly changing growth opportunit ies. The satellites feature an all-electric propulsion system and were bui lt using electronics from Boeing's flight-proven BSS-702X satellite plat form customized to support the unique MEO environment for at least 10 year s of service life. The second generation satellites will introduce a seco nd orbit of the same orbital height\, but at an inclination of 70° for ne ar-global coverage. The equatorial constellation will feature up to 24 sat ellites and the inclined orbit constellation up to 16.\n-\nDelayed from 20 23. Moved forward from July.

Main pay load is the third SAR satellite for South Korean Defense Acquisition Progr am Administration (DAPA)\, also known as KORSAT 4. It is the synthetic ape rture radar component of the 425 Project reconnaissance satellite constell ation\, which consists of an EO/IR sat and four SAR satellites. Also aboar d are Tomorrow-S9 & Tomorrow-S10\, San Xavier and four GUMUSH picosatellit es. The booster is designated B10XX.X for this mission and will perform a RTLS landing at LZ-4.\n-\nThe 800kg high resolution SAR satellites were de veloped by a consortium consisting of Korean Aerospace Industries (KAI) an d Hanwha Systems Corp with Thales Alenia Space providing the SAR payload. The Thales Alenia Space SAR payload uses a specialized 5m antenna folded a s 24 petals that will open in space to form a parabolic dish.
