Some context (emphasis added):

Press Release
N°42-2016

Paris, 14 November

Media backgrounder: ESA’s Ministerial 2016 in Lucerne

[...]

Goal: foster a globally competitive European space sector
Target amount: €1.5 billion 

Concerted measures that foster the European space sector into becoming wholly competitive in the global market are also about enabling and implementing new cooperation methods between traditional, new and emerging actors, about new working methods
in line with Industry 4.0 and about pushing for a self-sustaining and commercially competitive European space industrial base open and easily accessible to other European sectors, which it helps to make profitable.

This calls for broadening the base of industrial actors through the emergence of new players, including small- and medium-sized enterprises (SMEs), calls for implementing public–private partnerships (PPPs) in areas in which these have to date seen
only public financing, calls for clearer and stronger connections between the space and non-space sectors to allow for spin-ins and –offs, and for complementary activities.

ESA intends to address all of the above by:
•supporting the growth and networking of SMEs, through the SME Initiative, which helps to widen the base of actors and increase the dynamic nature of the space field;
•extending PPPs to the Earth observation area through InCubed (Earth Watch) to stimulate Europe’s Earth observation industry to develop innovative technologies and services for commercialisation in the new Space 4.0 environment;
•stimulating the first European commercial partnership(s) in space exploration, drawing on the group of innovative ideas already proposed by industry through commercial partnerships within the European Exploration Envelope Programme (E3P);
•coordinating space technology planning of ESA, EU and Member States with industry and other stakeholders through the establishment of technology roadmaps through technology harmonisation;
•providing support to the establishment and maintenance of standards for the space sector through standardisation;
•preparing future initiatives and developing competitive technologies and products for telecommunication and thus directly supporting industry competitiveness through the Future Preparation and Core Competitiveness Elements;
•providing extended geographical coverage and service enhancement of the European Data Relay Satellite System (EDRS), currently under development and opening new market opportunities for optical communication technologies, through the continuation
of the EDRS-GlobeNet programme;
•developing optical communication technologies to address future markets with ScyLight, which will also address quantum cryptography and other new applications;
•supplying a validated satellite-based communication solution for the European Air Traffic Management System, through Iris;
•supporting and enabling the development, qualification and demonstration in orbit of next-generation platform lines, allowing European prime satellite integrators already established in the 
3–6 tonne launch mass segment to address future satellite operators’ needs through Neosat;
•supporting the development, launch and validation in orbit of a satellite system based on an innovative geostationary platform in the 3 tonne launch mass range, using all-electric propulsion for transfer to geostationary orbit and for stationkeeping,
through Electra;
•supporting the design and development of the innovative elements that will contribute to an optimised delivery of future mobile satellite communication services, through ICE, Inmarsat Communications Evolution project;
•supporting the development, launch and validation in orbit of an innovative Ka- and V-band satellite system, through Lynxsat;
•supporting European satellite ground segment industry to develop, validate and roll out innovative ground segment solutions, through Aidan;
•supporting the development of streamlined microsatellites towards reduced recurring cost for serial production by supporting space-based tracking of seafaring vessels beyond coastal areas that are equipped with AIS (Automatic Identification System)
tracking devices through SAT-AIS missions and other applications and by addressing other opportunities offered by small LEO constellations high-performance ship detection capabilities;
•facilitating the transfer of technologies and knowhow developed at ESA into diverse non-space fields (spin-off) and supporting the local Business Incubator Centres in Member States, through the Technology Transfer and Incubation Programme (TTP); 
•preparing Europe for independent routine access and return from LEO with a reusable system able to transport payloads for several different applications through Space Rider (based on Vega C), and activities involving Dream Chaser (based on Ariane
64);
•providing low-cost launch services for light and small satellites based on Ariane 6 and Vega with the Light satellite, Low-cost Launch (LLL) initiative.

I really like the simplicity of the spacerider design. Just take the AVUM+ upperstage, integrate a solar power generation system and you have the orbital maneuvering system for SpaceRider.
It also looks like they are going to use the same configuration as IXV. (only replacing the parashute recovery system with a payload bay, and switching to land landing.

I wonder what other uses ESA/ASI/AVIO can come up with for the AVUM+ with power generation system!?
Let's hope for the best for the SpaceRider program.

ESA aims to privatize Space Rider unmanned spaceplane by 2025

Excerpt:
Quote

LE BOURGET, FRANCE — Although Europe’s Space Rider reusable spaceplane is three years or so from its debut, the European Space Agency is already making plans to privatize the unmanned orbital vehicle.

By 2025, ESA officials said, Space Rider could be operating commercially, flying science payloads and bringing them back to Earth for roughly $9,200 per kilogram.

Arianespace, the Evry, France-based launch services provider, would likely serve as Space Rider’s operator, offering industry and government customers the opportunity to fill the spaceplane 800-kilogram payload capacity with microgravity science, materials testing, telecommunications and robotics demonstrations.

How could Space Rider operate commercially if they're charging less than $10k/kg of payload?  Wouldn't it need to charge more than 5 times that much?

Most basic 1U volume rideshare service. Cube up and down, passive payload.
Add power and date for more advanced payloads and you can multiply the cost possibly an order of magnitude.
I guess the cost per mission (800kg payload) is in the order of 50-100mln.

Last I heard, the target recurring cost (incl. launcher) is well below $50m. Unfortunately, even with a highly reusable airframe, the relatively high launch cost and the expendable AVUM+ stage will always preclude costs from falling below $30m/flight...

The figure I got when I googled was $40K/Kg, that's $32m for an 800Kg payload (is that figure current ?)

Until I was checking some stuff related to IXV I had no idea this programme existed.  :o
 Now it looks like it's going to launch within 5 years.

Thanks Calapine, it was an interesting document indeed.
To me it's not at all surprising that the IXV (with small wings) is favored. The spacerider is the continuation of the IXV project, Italy is the main funder of this project, they also backed IXV the most.

This document only studied vehicles launched underneath a payload fairing. I wonder how the preference changes when launching without fairing.
If I'm not mistaken, SpaceRider will launch on Vega-C or Ariane 62; IXV launched on Vega.
All three launchers have different fairing diameters (Vega 2.6m, Vega-C 3.3m, A62 5.4m outer diameter)
The baseline is a reuse of the IXV vehicle shape, so I wonder if they are going to use the Vega fairing on Vega-C when launching SpaceRider or if they are going to use the larger fairing. The advantaged of using the smaller fairing is that it weights less so the vehicle mass might be higher.
When using the larger fairing a lot of volume won't be used.

I forgot to add that this IXV configuration might also be usefull for a reusable upperstage / space vehicle. (Like BFR)

SpaceRider will launch on Vega-C (with an adapted AVUM as kind of an orbital module). Neither Vega nor A62 is foreseen. The Vega-C fairing will be used, simply because that will be the only fairing qualified for the launcher. A different fairing would require a system qualification loop (different aerodynamics with impact on guidance laws). That is also the point why IXV was and SpaceRider will be launched under the fairing: The use of a qualified launcher configuration.

ESA signed two contracts today with Italy’s ELV and Thales Alenia Space to extend Europe’s Vega space system capabilities and competitiveness, and develop Space Rider for payload return capability.

Quote
... Thales Alenia Space and ELV will complete the detailed mission and system design up to the Critical Design Review for Space Rider.

The Space Rider space transportation system will be integrated with Vega-C, combining an Orbital Service Module derived from a Vega-C AVUM and a reentry module derived from the Intermediate eXperimental Vehicle (IXV) demonstrator flown in 2015 on Vega.

It will provide Europe with an affordable reusable platform for routine access and return from space, with payloads capacity up to 800 kg to an array of orbit altitudes and inclinations for multiple applications such as advanced microgravity, in-orbit demonstration and validation for Earth observation, science, telecommunication and robotic exploration.

I think the SpaceRider contract is for the preliminary design, the full development of SpaceRider will most likely be one of the projects asking for funding during the 2018 ministerial conference. 
SpaceRider will most likely be used to test and demonstrate new technologies in space. IOD (In Orbit Demonstration) should reduce the time and risk of marketing new space/satellite technologies. Examples are:
- faster space computers, 
- faster larger SSD's,
- new green in orbit propulsion (ion/electric, mono and bipropalent)
- smaller star- and sunsensors,
- new sensors/ different measuring technologies.
- (A specific one) new atomic clocks for Gallileo Gen2
IOD can be done using the ISS, dedicated demonstrator satellites (cubesats), hosted payloads and space test vehicles like SpaceRider and DreamChaser. You could see SpaceRider as a reusable satellite bus, testing new systems, payloads and sensors each time it launches. Cubesat/microsat deployment is a option, but it's a expansive ride (2.2mT launch for 0.8mT payload), a normal rideshare is far cheaper.
SpaceRider can also be used for experiments that are to dangerous for the ISS. This could be the 5th facility for doing microgravity science,  besides: drop towers, parabola planes, sounding rockets(New Sheperd) and the ISS (LEO science station). In my oppinion science and research in microgravity is the third most importent activity in space, after Comsats and EarthObservation. I think Space exploration is far less importent than the former three activities, but human space exploration requires by far the largest budget.
I realy hope ARTES and Galileo will also include a hosted payload component.

Let's also add that I'm curious how  SpaceRider will be implemented on Vega-E. Possibly they could use the same equipment for a modified version of AVUM and the VUS upper-stage. Another option is including the upperstage functionality in SpaceRider (solar array and propulsion system). A third option as a expendable propulsion and power generation module.

From avio's press release

Quote
Today, Avio signed two contracts with ESA, the European Space Agency, in Paris to develop the Vega E launcher and the Space Rider re-entry vehicle, in line with market expectations. The contracts are worth a total of €89.7 million.

Quote
Space Rider is a re-entry vehicle, the evolution of the IXV (Intermediate Experimental Vehicle, launched by Vega in February 2015), capable of ‘navigating’ up to 2 months in low Earth orbit before returning to earth. Re-entry enables the recovery of all the useful load that can be analysed, and the vehicle to be reused for a new mission. The contract signed by ESA with Avio and TAS-I (Thales Alenia Space Italia) is worth a total of €36.7 million for the development of the Space Rider system, consisting of two modules: AOM (Avum Orbital Module) and RM (Re-entry Module). Avio will handle the development of AOM, a specific version of AVUM (fourth stage of the VEGA C) capable of supplying power and services for controlling the vehicle’s re-entry attitude during the orbital stage.

THALES ALENIA SPACE SIGNS WITH EUROPEAN SPACE AGENCY THE SPACE RIDER PRELIMINARY DEVELOPMENT CONTRACT

30.11.2017

A successor to the IXV reentry demonstrator, Space Rider is Europe’s next-generation reusable transportation system for low Earth orbit
 
 
Paris, November 30, 2017 – Thales Alenia Space (Thales 67 %, Leonardo 33 %), with ELV (European Launch Vehicle - 70% Avio SpA, 30% ASI)  as co-contractor, has signed a contract with the European Space Agency (ESA) for the engineering and preliminary development of the automated reusable Space Rider transportation system, designed for deployment by the new Vega C light launcher into low Earth orbit (LEO).

The goal of Space Rider is to provide Europe with an affordable, independent, reusable end-to-end integrated space transportation system for unmanned missions and for routine access and return from low orbit. It will be used to transport a variety of payloads into different LEO altitudes and inclinations.

Featuring a lifting body configuration, Space Rider is designed as a free-flying orbital platform, capable of remaining two months in orbit, safely reentering the atmosphere and landing. It can be recovered along with its payload, refurbished, and reused for up to six missions. It combines the characteristics of a space system designed for scientific experiments in low Earth orbit with those needed for guidance outside the atmosphere and through an automated landing, including microgravity experiments, in-orbit validations, testing of science and exploration technologies, etc., plus payload recovery on the ground for examination and retesting.

It follows ESA’s Intermediate eXperimental Vehicle (IXV) which on 11 February 2015 performed a flawless suborbital flight with atmospheric reentry and sea landing.

Leading a consortium of European manufacturers, research centers and universities, Thales Alenia Space is responsible for the development of the reentry module (RM), derived from the IXV. ELV is in charge of the development of the service module, derived from the Vega C upper stage AVUM (Attitude and Vernier Upper Module). The partners in this new program are capitalizing on the lessons learned from the IXV, which enjoyed strong support from the Italian space agency ASI.

Space Rider way forward

Phase-B1 was completed with the system requirements review board meeting on 21 December 2017 concluding that the project is technically sound.

Activities for Phase-B2/C, covering the preliminary design review and the critical design review, started on 25 January 2018. 

Increasing the volume of the multipurpose cargo bay is a priority to allow for more or larger payloads on each mission. Another focus is to refine the mission operations and the requirements for the ground segment together with the consolidation of the business plan on exploitation.

Section underlined (by me) appears to be new.

Seem like they marketing this commercially, suspect alot of payloads will be ESA's or sponsored by them. At couple missions a years helps boost Vega C flight rate.
The big plus for ESA is giving them an alternative to ISS which they in total control of.

So is any part of this reusable? I get that it can bring experiments back to earth, but it looks like there will be, effectively, no real reuse going on here.
The "Re-entry Module" is intended to fly a minimum of 6 missions (i.e. be re-used at least 5 times), with a turn-around time of 4 months (TBC).
From the fact sheet:
https://esamultimedia.esa.int/docs/space_transportation/Space_Rider_factsheet_HiRes_ok.pdf
Right, but what all hardware on it gets to be reused? Thrusters, tanks, and power are on the service module. The heat shield is presumably expendable. How much valuable hardware is left?

Maybe I'm just looking at it wrong and the concept is supposed to be a standardized reentry vehicle for taking experiments up and back down, rather than a reusable spacecraft?

Space Rider - Developing ESA’s Autonomous Space Vehicle Capability
Mr A. Godfrey, Lockheed Martin UK – Ampthill, July 2017

Abstract
The ever increasing demand to access Low Earth Orbit (LEO) has prompted a recently
renewed global interest in Launch Vehicle (LV) and Space Vehicle (SV) development. The
primary aim of new designs has been to reduce the cost of accessing space, often by
maximising vehicle reusability. Despite recent test and demonstration successes, the maturity
of the European Space Agency’s (ESA’s) reusable LV and SV technology is still considered
to be below that of major space fairing nations; the United States, Russia and China. To
address this knowledge gap and maintain pace with the rest of the world, ESA have been
developing an autonomous and reusable SV capability known as Space Rider.
Initially this paper discusses why an agency or nation may want to develop an autonomous
SV and goes on to present an overview of SVs, both past and present. ESA’s SV development
with its Space Rider programme and preceding demonstrator, the Programme for Reusable
In-orbit Demonstrator for Europe - Intermediate eXperimental Vehicle (PRIDE IXV), are then
introduced. Following this, an overview is given as to how Lockheed Martin UK – Ampthill
(LMUK Ampthill) have been contributing to the development of three critical Space Rider
subsystems; the Aerodynamic Surface Control System (ASCS), Landing Gear and Mid-Air
Retrieval (MAR) system. Key design drivers and trade-offs are highlighted to illustrate some
of the engineering challenges associated with developing an autonomous SV. Finally it is
shown how SV operators can realise a large cost saving by using MAR instead of conventional
Landing Gear.

Aerospace, green light to the development of a new made in Italy ceramic material

Interesting prospects are opening up for the development of a new made in Italy material with applications in the aerospace sector.

The new opportunities are opened by the success of the tests carried out on an innovative material for thermal protection developed by CIRA, the Italian Aerospace Research Centre, in collaboration with Petroceramics, a company specializing in the development of high-performance ceramic matrix composites.

The material was tested in CIRA’s Scirocco plasma wind tunnel on an aerospace component exposed for 10 minutes to conditions simulating the re-entry conditions from low Earth orbit. The component reached temperatures of about 1200 degrees Celsius showing no sign of degradation, thus proving that it can be employed as a reusable thermal protection.

The material resulting from the collaboration between CIRA and Petroceramics proved to be able to withstand extremely high thermal and mechanical stresses in an oxidizing environment. It is a completely new reinforced ceramic composite with the advantage that it can be produced in a rapid, cost-effective manner.

The field of application is that of space re-entry technologies. In particular, the positive result of the tests on the new material opens the way for the development of made in Italy thermal protection systems, also useful in view of future programmes of the European Space Agency, such as Space Rider...
