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!

We can currently provide global satellite coverage with the 618 craft already in orbit, but these extra satellites are set to be added to the constellation to provide extra resilience to our high-speed, low-latency network 🛰️

Given the total mass of the 21 satellites, will this launch use an OCISLY landing?

Launch is scheduled for Early-May and will include 15 Gen1 OneWeb satellites, as well as 1 Gen2 prototype.

Launch mass will be 6.660kg = (147,5kg * 16) + (860kg * 5), so should be able to RTLS, which SpaceflightNow is also listing:

The Falcon 9’s first stage booster will return to Landing Zone 4 at Vandenberg.

Which first stage will be used for this launch?

Available first stages, with date of most recent recovery:
1071.9    Mar 17
1075.3    Apr 2 Starlink 2-9
1063.11  Apr 15

Edit May 15: It's B1063.11.

First stage landing aboard OCISLY.

Leading from this, perhaps the second stage will use a short nozzle Merlin Vac?

Any news regarding delivery of the Iridium quintet for launch processing?

[michaelmalinsky]

The last official launch of 15 Generation 1 Constellation satellites, plus one advanced broadband satellite (Gen2 prototype) that will provide high-speed internet connectivity from low Earth orbit, will launch from Vandenberg Space Force Base aboard a SpaceX Falcon 9 later this month along with a payload from Iridium.

The beam-hopping satellite – nicknamed JoeySat after a baby kangaroo – will demonstrate connectivity for people traveling by air, sea or on land, and preparing for low latency 5G connectivity from space.

Led by OneWeb, the industrial partners have received over £32 million (€37m) from the UK Space Agency, via the European Space Agency’s (ESA) Sunrise Programme, for a demonstration satellite.

The satellite’s pilot beam-hopping payload was developed by SatixFy, based in Farnborough. The user terminal to support this satellite is also being developed by SatixFy, who have been awarded over £25 million.

The fully digital beam-hopping and beam-steering payload can switch the satellite capacity between different areas on Earth up to 1000 times per second. The signal strength can also be adjusted to meet demand.

This will enable JoeySat to respond to real-time surges in commercial high-quality and low latency connectivity demands — or during emergencies such as natural disasters, with rapid deployment of 5G Mini Hubs connected to the OneWeb communication network.

Developed under the Sunrise Partnership Project between ESA OneWeb, JoeySat will demonstrate key technologies for OneWeb’s next generation constellation, as part of the ESA Sunrise project with support from the UK Space Agency.

The advanced digital regenerative payload was built by SatixFy in the UK and the payload environmental tests were completed in the UK.

Project Sunrise Patch

Project Sunrise Patch

That is the patch for ELSA-M, which is a debris removal satellite launching at the end of 2024. This is also in cooperation with OneWeb, but I believe is a different satellite to JoeySat which is testing communications technologies.

ELSA-M is a different satellite then JoeySat, but JoeySat is part of the Sunrise Project and it is also the "Gen 2 Prototype"

May 19 Falcon 9 • OneWeb & Iridium Next
Launch time: TBD
Launch site: SLC-4E, Vandenberg Space Force Base, California

A SpaceX Falcon 9 rocket will launch 15 spare satellites for OneWeb’s first-generation global internet network and one prototype for OneWeb’s Gen2 second-generation network. Five spare satellites for Iridium’s voice and data relay fleet will also launch on this mission. The Falcon 9’s first stage booster will return to Landing Zone 4 at Vandenberg.

Introducing OneWeb’s mission patch for Launch #19 with @SpaceX. This launch will add another 15 satellites to our low Earth orbit fleet, plus a demonstration satellite called ‘JoeySat’.

Make sure to follow us for further updates ahead of launch.

This is not quite as finely drawn as usual SpaceX zones (not as many line segments), but the dimensions are quite comparable to Starlink 2-9 that just launched. I think this is SpaceX and thus perhaps a match to NSF's next launch slot "Iridium-9 & OneWeb #19".
