What happens near a black hole? How does ordinary matter come together in the large-scale structures we see today? How do black holes grow and shape the universe and what is the relationship between these processes? 

All these questions will be answered very soon by the Athena advanced telescope for high-energy astrophysics. “Athena will be a state-of-the-art observatory that will provide a significant leap forward in scientific capabilities compared with previous X-ray missions, and will address fundamental open questions in astrophysics,” says Alvaro Giménez, Director of Science and Robotic Exploration at the European Space Agency (ESA).

Austrian RHP Technology GmbH stands ready to contribute to ESA’s second ‘Large-class’ science mission. A total of six test parts have already been manufactured, which RHP Technology GmbH conducted in cooperation with AAC Aerospace and Advanced Composites and FOTEC Forschungs-und Technologietransfer GmbH.

The prototype is a 3D-printed and partly processed version of what may someday become the ‘eye’ of the ESA X-ray telescope Athena. This test structure was produced by an ESA-led 3D project to evaluate a promising method called ‘Plasma Metal Deposition’. 

“The project’s goal was to evaluate the technology’s ability to produce space hardware and  components larger than 0.5m,” explains ESA materials engineer Laurent Pambaguian. Dr. Erich Neubauer, Managing Director & Owner of RHP Technology GmbH says: “More than 80% of material is wasted by using a traditional method of manufacturing; which is typically milling from a block. By using our Plasma Metal Deposition technology, we were able to demonstrate a significant material and cost saving”. 

“We examined the entire process chain, including subsequent heat treatment and post-processing, as well as 3D printing, using titanium alloys either as metal particles or as wire material. The result has demonstrated good mechanical properties and finishing, signifying that we are capable to advance the technology, including the investigation of alternative materials.” 

Plasma metal deposition is a candidate for manufacturing large-scale components in the future, such as the Athena mission optical bench, which will be the most complex part ever printed in titanium. 

In a complex structure with many deep pockets tapering to a maximum height of 30 cm, the optical bench aligns and secures around 750 mirror modules. The overall shape must be accurate to within a few ten micrometers – or thousandths of a centimetre. “RHP demonstrated that large 3D parts can be printed for space applications. In the future this technology can be used for applications on Earth such as industrial, aeronautics or automotive applications,” says Susanne Katzler Fuchs from Brimatech, the Technology Transfer Broker for ESA Space Solutions in Austria.

When ESA's Athena satellite is launched in 2031, it will be 10-100 times deeper than in previous X-ray missions to observe the hottest, high-energy celestial objects.

Property tech start-up Orbital Witness is bringing a new way of thinking to property transactions. The London-based company won ‘IT Product of the Year’ at the British Legal Technology Awards 2020 in November with a unique product, developed in collaboration with ESA Space Solutions.

Orbital Witness’s hunch that property due diligence was trapped in the past (slow, costly, and an ‘indemnity hot potato’) turned out to be correct. With the support of ESA Space Solutions, the team has now created a platform for real estate lawyers to review and understand property risks with a much higher degree of insight and efficiency than has previously been possible.  

Time travel for real estate

Many questions in real estate law have a historic dimension but until now there’s been no easy way for a real estate lawyer to ‘look back in time’ and make enquiries relating to the past. Lawyers have had no choice but to carry out lengthy investigative processes or, on occasion, manually acquire aerial photography.

Orbital Witness now arms users with detailed historic information at the outset of a property transaction, using satellite imagery archives for a historic overview.

“Orbital Witness uses archives of very high-resolution (sub-1m) optical satellite imagery with enough clarity for real estate professionals to be able to spot important details such as a change of use at a site, a structural change to a property, or a boundary movement,” says Fausto Vieira, Technical Officer at ESA.

“The space added value of this satellite imagery provides the first standardised view for real estate professionals to visualise and give a reliable legal indication of the historic development of a site. It’s doubly impressive as this platform has the power to aggregate data from multiple sources.”

The pilot demonstration in collaboration with ESA Space Solutions saw the successful integration of satellite imagery archives and property datasets (such as contextual information sourced from places such as HM Land Registry) into a production-ready real estate intelligence platform. 

“This has the potential to reduce the cost and turnaround time it takes for property lawyers to deliver accurate and immediate insights to clients,” says Will Pearce, Co-Founder, Orbital Witness.  “Lawyers can finally start spending time on higher-value advisory work instead of lengthy, paper based due diligence.” 

Orbital Witness’ vision is to eventually build a ‘Universal Risk Rating’ for all types of property transactions – a solution that has the potential to automate due diligence for property transactions. 

“It’s a revolution in common sense where access to property information is front-loaded and simplified so anyone interested in real estate can get a clear picture of a property before spending significant amounts of time or money,” says Pearce. 

Orbital Witness, also an ESA BIC alumnus, is already at a commercial phase with a range of first customers adopting the product even before the end of the project. An extension to the project is currently being prepared, expanding the reach of the application to insurance and surveying sectors.
