Y tras el clicbait la noticia:

La empresa española Sateliot pretende crear una constelacion de 250 nanosatelites para dar cobertura 5g.
Sateliot, que prevé facturar 1.000 millones en 2025, se alía con Indra y Cellnex para extender la cobertura de los operadores móviles allá donde no llegan las antenas tradicionales.

Agrego a la noticia, la de que el Bezos ha acaparado prácticamente todas las ventanas de lanzamientos (mas de 80) disponibles en varios años menos las de SpaceX para lanzar su red satelital, por que el lo vale.

Las derivadas de esto son que:
- Todos los paises occidentales tendran a su disposición varias redes mesh satelitales espaciales de todos los colores y sabores.
- A ver quien lo replica.
- Indra es un gigante silencioso en temas de redes, radares y sistemas de control, lo de integrador ya le queda corto. No me extraña que en Lookheed no quieran ni verlos en sus contratos.
- Musk será el mayor proveedor de infraestructura de "satelites oscuros" del mundo.

Y la derivada fea:
- Mucha gente cuenta con que los cables submarinos van a empezar a tener "averias" a las primeras mal dadas gordas.



Pero quieres saber lo mejor de Sateliot. Quien le fabrica los nanosatélites es una empresa gallega.

May 27, 2022 | By Greg Hadley
...
As part of the deal, General Dynamics and its partners will establish two operations centers, one at Grand Forks Air Force Base, N.D., and one at Redstone Arsenal, Ala. It will also build 12 ground stations—eight for Ka-band frequencies, two for S-band, and four with optical communications, an SDA official told reporters.

SDA, which is scheduled to transition fully into the Space Force later this year, has already awarded contracts for more than 120 satellites and is looking to add still more to its first tranche of the constellation—Lockheed Martin, Northrop Grumman, and York Space Systems have all earned SDA contracts to design satellites, and more are to come.

It will be up to General Dynamics to develop “a common ground architecture, which integrates base and ground segments from multiple vendors in multiple configurations and allows … mission operations in a mesh networking control,” the SDA official said.

The Space Development Agency’s strategy includes awarding contracts to multiple vendors and encouraging unsuccessful bidders to try again for later tranches, as the agency looks to build an open satellite constellation without so-called “vendor lock.”

That approach, however, means that having a ground segment operator that can integrate all the different contractors into one system “really is the most critical element of Tranche 1,” the SDA official said, adding that it also “carries the highest risk for the overall Tranche 1 successful performance.”
...
All told, SDA is estimating that Tranche 1 of the NDSA will consist of 166 satellites—126 for the Transport layer, dedicated to data and communications that will serve as the “backbone” for joint all-domain command and control; 28 for the Tracking layer, which will detect, identify, and track hypersonic weapons and other advanced missile threats; and 18 for the Tranche 1 Demonstration and Experimentation System, which SDA says will augment the Transport Layer “with demonstration and experimental capability.”

The first Tranche 1 satellites in the Transport layer are slated for launch no later than September 2024, with the first Tracking layer satellites currently scheduled for April 2025. But first, SDA plans to launch “Tranche 0,” a relatively small collection of 28 satellites, no later than 2023. Tranche 0 will include 20 satellites in the Transport layer, 10 each from Lockheed and York, and eight in the Tracking layer, with L3Harris and SpaceX supplying four each.

Description
THIS IS A REQUEST FOR PROPOSAL (RFP). The Marine Corps Systems Command (MCSC), Quantico, VA, requires delivery of Marine Corps Wideband Satellite Communications (SATCOM) Light (MCWS-L) and Heavy (MCWS-H) Systems to the United States Marine Corps (USMC). The MCWS-L/H uses beyond line of sight terminals to provide access to the World Wide Web, Department of Defense (DoD) information network services, and Marine Corps enterprise services via DoD gateways, utilizing radio frequency and over the horizon transmission means. The work to be performed under this effort includes two separate phases for the MCWS-L and MCWS-H Systems. The first phase is to procure MCWS-L and MCWS-H Test Systems to support a Developmental Test that will include testing and logistics efforts to support the Government’s production decision. The second phase will consist of the production, testing, and delivery of systems to support the USMC’s fielding requirements. The phases will include deliveries of the following, as ordered: technical data, logistics data, training data, training support, fielding support, and sustainment support as well as any technology upgrades or engineering changes needed to maintain the relevance of the MCWS-L and MCWS-H systems.

Disclaimer: no tengo mucha idea.
En los motores cohete, uno de los quebraderos de cabeza de siempre han sido las turbobombas y sistemas de inyección en sus múltiples combinaciones, tambien la refrigeración. Veo que liberan el oxidante en la camara de combustion y este ya se ira mezclando y quemando "libremente". Dudo muchiiiisimo que tenga mas rendimiento que los motores actuales, pero queda claro que abarata bastante un elemento que has de desechar y ahí esta la clave.

Edito: y simplificar y tener menos elementos hace que la impresion metalica 3d haga acto de presencia. Rebaja los costes y acelera las iteraciones. Eso ya lo estan haciendo privadas y startups espaciales.

Se supone que esa es, precisamente, el quid de la tecnologia Vortex. El uso de tecnologias de vortices es muy comun en motores de combustion (interna). Casi todos los coches modernos la implementan. Llega desde las presiones y temperaturas de un cilindro a las de un motor cohete supongo que es el paso que te permite la impresion tres de.
