Some more details I found on the tourism version, "study" from EPFL and dassault:

Quote from: R7
Pegasus has an airplane plus a rocket and it turned out to be one of the costliest LVs ever. S3 has an airplane, a suborbital shuttle and a rocket...

Kind of depends on how big that remaining upper stage will be. I'm not sure at what speed they intend to release the upper stage when launching satellites.

Quote from: R7
Even if they ferry elsewhere to launch the reusable shuttle part demands a landing strip somewhere downstream.

Well I guess the landing strip would be at payerne.

From the Mail article:
Quote
The firm also plans to build its own spaceport in Payerne, although says in theory it could launch from any airport.

Other countries, such as Malaysia and Morocco, announced during the launch that they would be partnering with S3 in order to build spaceports in their countries too and discussions are under way with several other potential partners.

I suppose a runway nearer the equator would make sense. And in 20 years a large proportion of the world's satellites will be from Asian countries, so Malaysia to serve Asia and Morocco to serve Europe?

Will be challenging to do orbital launches from Switzerland, hard to find safe enough corridors through neighboring countries. Even if they ferry elsewhere to launch the reusable shuttle part demands a landing strip somewhere downstream.

I think that's the point of the pop-up trajectory; the first stage flies vertically to above the Von Karman limit, and then the upper stage(s) fly downrange technically in space. The first stage can then land at the same runway the carrier airliner used.

Quite possibly.  Remember that RpK planned on flights from, and return to, the Northern Nevada test range, with "pop-up" (or "pop-down") high angle trajectories designed to make such a site acceptable.

So? It still falls down if US fails.  ;)

It looks a lot like VEHRA...

Yes, I think clearly an evolution of that design and concept of operations:

http://www.flightglobal.com/blogs/hyperbola/2010/04/dassault-gives-k1000vehra-subo.html

It certainly looks the part, but am I the only one worrying about how close the spaceplane was to the A300's tail on separation in their video?!

Swiss Space Systems – S3 is Strengthening its network of partners and
will start developing passenger transportation from 2018


Le Bourget, 17 June 2013. Swiss Space Systems – S3, the young Swiss aerospace company, was officially launched on 13 March this year. Its goal is to develop, manufacture, certify and operate unmanned suborbital shuttles to launch small satellites up to 250 kg by 2018.

With the development phase well under way, the firm is announcing today a new partnership - with Thales Alenia Space, a leading developer and manufacturer of pressurised modules, notably for the international space station. These partnerships will enable S3 to move ahead with the plan to launch small satellites and enter the next stage of developing a manned version of its suborbital shuttle. The latter will enable the company to offer a very high speed mode of passenger transportation.

Work is progressing to schedule

Following the official launch of the company in March, the development work is going smoothly and S3's 40 or so employees are making rapid progress with the help of their partners and technical advisers, whose specifications have been defined and complied with. The technical data relating to the shape of the shuttle, its trajectory and the physical and thermal constraints are being validated prior to the first wind tunnel tests which will take place at the Von Karman Institute in Belgium in July. The certification process has also been initiated with participation in working sessions organised by the European Aviation Safety Agency (EASA), the body responsible for the drafting of and compliance with European aviation safety regulations.

A stronger international network of partners and advisers

To reach its goal of launching small lower-cost satellites so as to broaden access to space for companies, universities and countries that could not afford it hitherto, S3 already benefits from the valuable support of prestigious partners. The French Dassault Aviation, consultant aircraft maker for the shuttle's systems architecture, is one of them, as are the Belgian Sonaca for the external structure, Space Application Services for the flight software and the Von Karman Institute for the wind tunnel. Other partners are the Spanish Elecnor Deimos for the navigation, the Swiss Meggitt for the sensors and Spaceport Malaysia for the ground infrastructure. The technical advisers are the European Space Agency (ESA), the Swiss Space Center to which the EPFL belongs, and Louvain (Belgium) and Stanford (USA) universities. The main sponsor is Breitling, the Swiss watchmaker.

Today Swiss Space Systems is pleased to announce the creation of another powerful partnership with Thales Alenia Space, a global aerospace major specialising in particular in the development and manufacture of pressurised modules, including the Columbus module on board the International Space Station (ISS). The latter is one of the many achievements of this company that enable humans to stay alive in space.

Passenger transportation the goal of a new stage in the S3 project

The Memorandum of Understanding (MOU) between Thales Alenia Space and Swiss Space Systems will enable the project to move ahead, so that academic clients can be offered micro-gravity and biological research applications. The collaboration that will then be initiated with the ESA Astronaut Centre will enable S3 to move on to the next stage in its development, i.e. very high speed passenger transportation, which will open the way to the transportation of the future. The satellite flight certification process will in fact enable a substantial body of knowledge to be established with respect to the development of a manned version of the SOAR suborbital shuttle. Thanks to this, and to the new skills that will have been learned from the best, S3 intends to write a new page in the history of aviation by making supersonic intercontinental travel possible. This new mode of transport will link continents at Mach 3 speed, or three times the speed of sound.

Pascal Jaussi, founder and CEO of Swiss Space Systems says : "Far from wishing to launch into the space tourism market, we want rather to establish a new mode of air travel based on our satellite launch model that will allow spaceports on different continents to be reached in an hour. Apart from Malaysia, discussions are well advanced with numerous other countries such as Morocco, Ecuador and Canada, all of which want to build the sort of infrastructure from which we will be able to operate satellite launches and later passenger transportation. The priority remains the launching of small satellites, with the development phase at the moment and then the construction of the life-size model, the goal being to carry out the first commercial launches in 2018." Manned flights on the other hand will be offered at a later stage.

Reaching spaceports on different continents in an hour is gonna be difficult with Mach 3  ::)

As we all know almost orbital speed is required for that, so I'm not quite sure what they're up to.

It seems like their plan is to first build the Mach 3 system.  Then, if they can reach Mach 3, by induction they can reach Mach 25.  Because their system will magically evolve to that.  They're concentrating on the first step, so they haven't worked out the details yet of how to get from step 1 to step 3.

I've seen this plan before:

Yeah, they seem to be implying that the transport vehicle is directly related to the suborbital vehicle. IMHO, that implies replacing the airliner with a supersonic carrier plane. That could work technically, but would be rather expensive for trans-oceanic flights...

That looks like an accident waiting to happen...expecting an unpowered brick with stubby wings to clear a massive vertical stabilizer? Wouldn't want to be the carrier aircraft pilot.

28 launches  :o, well they certainly know how to sign contracts.

In Silicon Valley, it's not unusual for a couple of start-ups to make an announcement about a deal they've signed.  They make it sound like one of the companies is buying a lot from the other, when in fact the actual contract is often just some sort of option.  In many cases, nothing ever happens because one or the other of the companies never gets the funding it needs, and the contract doesn't have any binding obligations anyway.

Is this that kind of contract?  There's no way to tell from the announcement.  Some of the wording used suggests there's no real substance, such as, "signature of a contract relating to the launch".  Maybe that's just poor translation into English from a non-native speaker, or maybe it's an indication the contract isn't a firm order with a deposit behind it.

This may be more like a letter of intent that a firm order with financing to back it up.

The satellites placed in orbit by S3 for Spacepharma will have a weight of 5 kg;

What's the rest 245kg of the predicted capacity? Have 28 primary micro/minisat customers signed up too?
