Launch week: August 24-30, 2026
Five dated launches span August 24–30 UTC, including two SpaceX Starlink missions, Europe’s MTG-I2 weather satellite and NASA’s Roman Space Telescope, with payload gaps and webcast links marked.
Five launches have dated slots in the August 24–30, 2026 UTC calendar: two Falcon 9 missions on August 25, another on August 26, Europe’s MTG-I2 weather satellite on August 27, and NASA’s Roman Space Telescope on August 30. A Long March 6C mission remains payload-unknown. 12
All times below are UTC.
NET means no earlier than; TBD means the source has not settled or disclosed the field. The Next Spaceflight detail pages label their displayed local times as CST; the times below convert those values from China Standard Time (UTC+8). The conversion puts MTG-I2 on August 27 and Roman on August 30, matching the ESA and NASA dates. 34Quick schedule

Mission cards
Long March 6C: a launch slot without a payload
CASC's Long March 6C mission is planned for 03:20 UTC on August 25 from LC-9A at Taiyuan. The detail page names Long March 6C, while its launch notes say that the payload and launch vehicle identities remain uncertain. The payload, customer and destination orbit therefore stay TBD in the calendar. 5
The slot is useful for a calendar alert, but the mission's value for launch watchers is the vehicle and site rather than a known customer mission. No mission-specific webcast appears on the detail page. 5
Starlink Group 10-49: an early Florida window
Starlink Group 10-49 has a target of 09:33 UTC on August 25 from SLC-40. The four-hour window opens at 05:49 UTC and closes at 09:49 UTC. Spaceflight Now gives the same 05:49 UTC opening, while SpaceX's mission page displays the corresponding 13:49–17:49 China Standard Time range. 26
SpaceX is targeting 29 Starlink v2-mini satellites for low Earth orbit. The official mission page carries the webcast and says the feed begins about 10 minutes before liftoff. 6
Starlink Group 15-22: Wednesday from Vandenberg
Starlink Group 15-22 is planned for 09:27 UTC on August 26 from SLC-4E at Vandenberg. The official page gives a 17:27–21:27 China Standard Time launch range, which converts to 09:27–13:27 UTC. 710
The mission carries 27 Starlink v2-mini satellites to low Earth orbit. SpaceX's mission page is the direct webcast destination and says the live feed begins about 10 minutes before liftoff. 7
MTG-I2: Europe's weather satellite
ESA lists MTG-I2 for August 27 from Kourou on Ariane 6. Next Spaceflight's detail page gives 04:10 CST on August 28, which converts to 20:10 UTC on August 27. Spaceflight Now also lists the launch window opening at 20:10 UTC. 238
MTG-I2 is the second Meteosat Third Generation imaging satellite. ESA describes the programme as a six-satellite system that will provide weather data from geostationary orbit. The schedule record lists the payload at 3,760 kg and the destination as geostationary transfer orbit. 38
Nancy Grace Roman Space Telescope: Sunday’s NASA flagship
NASA lists the Roman Space Telescope for August 30, and Next Spaceflight gives a target of 11:26 UTC from LC-39A on a Falcon Heavy. The observatory is designed to study dark energy, exoplanets and infrared astrophysics. Its destination is the Sun–Earth L2 point. 49
Roman carries the Wide Field Instrument and the Coronagraph Instrument technology demonstration. The mission-specific SpaceX page is the webcast destination; a launch-window close is still TBD. 49
Watch priorities
- Set the first alert for Aug 30, 11:26 UTC. Roman is the week's NASA observatory mission and has a mission-specific SpaceX webcast page. 49
- Keep Aug 27, 20:10 UTC for MTG-I2. This is the week's European weather-satellite launch. ESA's page gives the August 27 date and Kourou location; Spaceflight Now supplies the UTC opening time. 23
- Add both Starlink alerts separately. Starlink 10-49 uses Florida's SLC-40 at 09:33 UTC on August 25; Starlink 15-22 uses Vandenberg's SLC-4E at 09:27 UTC on August 26. Both have direct SpaceX webcast pages. 67
- Treat Long March 6C as a provisional watch. The 03:20 UTC slot is dated, but the payload, customer and destination remain undisclosed. 5
Coverage notes
The current Next Spaceflight list has five dated entries inside the August 24–30 UTC window. Month-only records such as
NET August remain outside the dated count because a month does not establish that the launch falls between Monday and Sunday. 1Rocket Lab's official launches page gives its next dated mission, Owl Around The World for Synspective, as NET August 31 from Launch Complex 1, one day after this issue's Sunday cutoff. 11
NASA's retrieved launch-events page lists Roman on August 30; the retrieved ISRO launch-missions table contains no August 24–30 entry. ESA's mission page lists MTG-I2 on August 27. 3412
The Blue Origin missions page returned a security checkpoint during this run. The current Next Spaceflight list showed no dated Blue Origin mission in this week's window, so the Blue Origin check remains provisional. 113
Launch dates, windows and webcasts can change after publication. Recheck the operator page before setting an alarm, especially for the payload-unknown Long March 6C mission and the missions whose windows are marked
