Iridium-9 & OneWeb #19
Launch Time
NET May, 2023
One of the 16 OneWeb satellites is a demonstration version of the second generation of these satellites which will be deployed in the future to increase the capabilities of the constellation.

Rocket  Falcon 9 Block 5
...
Mission Details
Iridium-9
Five Iridium Next satellites will help enhance the Iridium Constellation. The launch was contracted in 2022 to replace some of the 75 Iridium satellites SpaceX deployed between 2017 and 2019. Iridium has 66 operational satellites, 9 on-orbit spares and 6 ground spares.
Payloads: 5    Total Mass: 4,800 kg  Polar Orbit

OneWeb #19
The first flight rideshare to the OneWeb high-speed Internet constellation. The initial constellation consists of 648 satellites. Later, the constellation could be expanded to more than 900 satellites depending on demand. OneWeb is expected to begin customer demonstrations in 2022, then provide a global, 24-hour service in 2022/2023.

Спойлер

Each satellite in the constellation weighs 147.7 kg. They are powered by Russian ion engines, manufactured by OKB-Fakel, and have two solar panels for their power supply. The first generation of satellites, operating on a quasi-polar orbit (1 200 km x 86.4°), cannot perform inter-satellite communication, and can only be used near a ground relay station.

The satellites will provide user service in the Ku-band, communicating in the microwave range of frequencies in the 12-18 GHz portion of the electromagnetic spectrum.

The satellites use a technique called "progressive pitch" in which the satellites are slightly turned to avoid interference with Ku-band satellites in geostationary orbit. The user terminal antenna on the ground will be a phased array antenna measuring approximately 36 by 16 cm and will provide Internet access at 50 megabits/second downlink bandwidth (almost certainly less uplink, but this number remains hard to pin down). The satellites will be designed to comply with orbital debris-mitigation guidelines for removing satellites from orbit and, for low-orbit satellites, assuring that they reenter the Earth's atmosphere within 25 years of retirement.

OneWeb  @OneWeb
Road trip!
Last week, 16 satellites travelled from the @OneWebSatellit1 factory in Florida over to Vandenberg, California, ahead of #OneWebLaunch19 with @SpaceX – expected no earlier than next month.

A huge shout-out to our colleagues and the drivers who made the trip!

The 15 Gen1 OneWeb satellites and 1 Gen2 satellite for OneWeb's 19th launch have arrived at Vandenberg Space Force Base. The satellites are scheduled to be launched together with 5 Iridium-NEXT ground spare satellites early next month aboard a Falcon 9.

SpaceX is targeting Friday, May 19 at 6:19 a.m. PT (13:19 UTC) for launch of the Iridium OneWeb mission to a low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. A backup launch opportunity is available on Saturday, May 20 at 6:15 a.m. PT (13:15 UTC).

The Falcon 9 first stage booster supporting this mission previously launched Sentinel-6 Michael Freilich, DART, Transporter-7, and seven Starlink missions. After stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

A live webcast of this mission will begin about 15 minutes prior to liftoff...
