LVs have large launch radius with is dictated by what is downrange of it. What is Spinlaunch radius, as it seems to be fixed launching in one direction.

Are you speaking of available launch azimuths, or expected range safety zones?

A fixed installation would imply a fixed launch azimuth, and due to the ballistic nature the projectile would have a pretty narrow safety zone (but possibly very long due to any launch underspeed events), assuming the fixed installation can handle a direct hit from a bad release...

In theory, if the outer building (the one with the door that opens when the vehicle is flung from the sling) can also rotate, it could aim at different azimuths. Although since I believe the plan was to position the facility on the side of a hill, so there would be a natural upwards angle, then the farther you rotate from that optimal azimuth, the lower the angle you get.

NanoAvionics Secures €122.5M Contract to Build 280 Satellites for Meridian Space, SpinLaunch’s Global Broadband Constellation [Apr 3]

Quote
Meridian Space, SpinLaunch’s next-generation satellite communication solution, has selected Kongsberg NanoAvionics (NanoAvionics) as its exclusive satellite supplier for the initial tranche of its low Earth orbit (LEO) broadband constellation under a contract valued at 122.5M EUR. The partnership between SpinLaunch and NanoAvionics includes two prototypes, one of which is an in-orbit demonstrator (IOD) mission planned for 2026, as well as the development and serial production of 280 satellites.

Beyond the initial batch of 280 satellites, the Meridian Space constellation will grow to at least 1,200 satellites, as outlined in the company’s 2021 spectrum filings. To meet the 280-satellite constellation production schedule, NanoAvionics will ramp up its manufacturing capabilities with the addition of a new assembly and testing facility at its European headquarters in Vilnius, Lithuania. NanoAvionics also aims to continue supporting Meridian Space in scaling the initial network through its experience in serial production and system customization.

Using a proprietary suite of groundbreaking technologies, including ultra-efficient reflectarray antennas, first-of-its-kind orbital architecture featuring a repeating ground track, as well as simplified user terminals and gateways, the Meridian Space satellite network will deliver affordable broadband connectivity worldwide. Its unique design, combined with the high-performance avionics and payload, will allow the satellites to deliver uninterrupted global connectivity with terabits-per-second capacity in a single rocket launch. The network is designed to meet the growing demand for flexible, high-speed and secure satellite communication services for enterprise users globally.

The IOD mission will demonstrate Meridian’s highly efficient communications payload onboard NanoAvionics’ standard MP42 microsatellite bus. NanoAvionics’ standard flight-proven platforms provide a reliable, cost-effective solution that accelerates the mission timeline and ensures efficient payload performance validation.

Simultaneously with the IOD phase, NanoAvionics, in collaboration with SpinLaunch, will develop a tailored satellite optimized for higher performance and launch efficiency. Approximately 70 kilograms each, the satellites for this project are lighter than currently operational satcom platforms and are designed to provide significant performance advantages per kilogram.

They've pivoted away from the SpinLaunch concept?

Just looking at what they are proposing, they are saying 280 satellites at 70 kg each with a deployment on potentially a single launch. That would be roughly 20 tons. So maybe a single New Glenn?

On the face of it it doesn't seem like a completely terrible idea, as long as the satellites are anywhere near as good as they say. A way to get around the high cost of launch when you don't have your own satellite launcher is to be very efficient with the launch mass.

I'm still not sure what I think about this exactly.
On the one hand, if you wanna be a highly profitable space business in the next 10 years, this does seem to be the thing to do.
On the other hand, I'm not positive there are gonna be prizes for 4th place in this particular market. After StarLink, Kuiper, AST SpaceMobile's constellation (plus OneWeb, I guess), is there gonna be room in the market for another?
Wait, ∆V? This site will accept the ∆ symbol? How many times have I written out the word "delta" for no reason?

I do like the 'hexleaf' physical layout: as well as the 3-around packing they showed in the video, the cutouts on the outer edge can also tesselate 'back to back' to create a 2-packing for smaller diameter launchers. Packing density will be higher than both square/rectangular 'flatsats' (e.g. Starlink) or non-flat packed layers (e.g. Oneweb, Iridium Next) and nearly as dense as Rocket Lab's Flatellite, but able to accomodate more vehicle diameters than the circular Flatellite. 
They've pivoted away from the SpinLaunch concept?
No indication of that, they signed a MOU for building a 100m diameter launcher on Adak Island earlier this month. Supporting your launcher R&D with constellation revenue is already something that works in practice.

NOTE:  This is a third-party Space News consolidator, not directly from the company. However, since SpinLaunch has little news, at least we can get some updates on where they are looking to locate this.

SpinLaunch Picked A Location For Its Orbital Accelerator[/b

Quote

Jun 15, 2025
The last time SpinLaunch tested its suborbital accelerator and provided an update on it was in late 2022, nearly 3 years ago. In the time since then, we’ve heard practically nothing with the exception of issues related to finding a location to start building its larger Orbital Accelerator. That was until recently, when it was confirmed that a lease was signed for a future launch site in Alaska.

Despite changes in leadership, a lack of updates, and a shift of focus to a new satellite constellation, it seems that SpinLaunch is still working on an Orbital Accelerator. For context, this company has been aiming to build a kinetic launch system that spins payloads at thousands of miles per hour before releasing them into the atmosphere.

It's Tony De La Rosa... I don't create this stuff; I just report it.  I also cover launches and trim post (Tony TrimmerHand).

SpinLaunch Announces Closing of $30M in Funding to Accelerate the Development of the Meridian Space Constellation [Aug 18]

Quote
SpinLaunch today announced it has closed $30 million in funding to accelerate the development and commercialization of Meridian Space, its highly differentiated low-earth orbit (LEO) satellite broadband constellation. The funding includes new investment from existing investors, including lead investor ATW Partners, as well as the previously announced strategic investment from Kongsberg Defence & Aerospace.

[...]

With this latest capital infusion, SpinLaunch is advancing toward its first customer link in the second half of 2026 and accelerating go-to-market efforts. Early commercial traction signals growing demand for a cost-efficient LEO satcom system with open architecture - purpose-built to deliver flexibility, seamless integration, and long-term value for customers.

[...]

As part of this next phase, SpinLaunch has successfully completed full-scale testing of its proprietary multi-band reflectarray antenna, a key breakthrough enabling the constellation’s ultra-low capex design. Unlike conventional satellite antennas, which can be bulky, power-hungry, or prohibitively expensive, SpinLaunch’s reconfigurable reflectarray antenna offers a compact, energy-efficient, and scalable solution built for next-generation LEO networks.

We and SpinLaunch have cleared multiple milestones in recent weeks towards its Meridian Space broadband megaconstellation for enterprise users:

 • SpinLaunch completed lab testing of its novel reflectarray antenna, demonstrating the critical functions required for its low-mass, high-throughput satellites.
 • Our teams successfully closed the Delta Design Review for SpinLaunch's First Customer Link mission, hosted on our standard MP42 microsatellite bus, and booked its launch.
 • We concluded a FlatSat training session for SpinLaunch, so their team could perform hardware-in-the-loop testing and develop the software interface between their payload and our MP42 bus.
 • First Customer Link satellite flight hardware entered production.
 • We made substantial progress towards our new European satellite factory, which will house serial manufacturing lines for the initial 280 Meridian Space constellation satellites and other large customer orders. More on that next month, during our presentation at Space Tech Expo Europe.

Via Satellite: Rethinking the LEO Constellation: Massimiliano Ladovaz on SpinLaunch's Plans for Meridian Space [Dec 2]

Quote
SpinLaunch is working with Kongsberg NanoAvionics on the constellation and recently announced that it completed a design review for the first customer link satellite, set to fly in October 2026.

[...]

VIA SATELLITE: We’re talking about Meridian Space, but what about SpinLaunch? What is the latest on the launcher development?

Ladovaz: The launcher has been demonstrated 10 times successfully. There is a lot of IP in order to demonstrate that launch. The next step is to fund the bigger, orbital accelerator. The revenues from Meridian will fund the accelerator. The cost of that launcher is again, a fraction of any traditional launcher. Everybody else is trying to copy Elon — good luck. You have to look at the problem in a different way.

In terms of steps, first Meridian, then we fund the accelerator. That accelerator has a lot of features on top of cost that are quite interesting for launching constellations. For replacing satellites, you can launch exactly on the orbit you want, and the time to service is practically zero. This being said, we still have some work on it. We are working with some partners. This is one of the largest vacuum chambers in existence, and you know hypersonics is a hot topic. Without getting too into details, people are quite interested in doing some testing and work on that aspect.

Transporter-18 launch?
