Video: First Hot Fire Testing of 75kN HyImpulse Hybrid Rocket Motor

Video Caption: At midday of Tuesday 15 September, the first firing of the HyImpulse 75kN hybrid rocket motor was a full success! It was performed at the world class DLR Lampoldshausen testing facility.

This is the biggest hybrid rocket motor ever built and tested in Europe. This marks an important milestone in accomplishing our plan for a suborbital flight in early 2021 and the first flight of the three stage HyImpulse launcher SL1 by the end of 2022.

How In­tense and Dan­ger­ous is Cos­mic Ra­di­a­tion on the Moon?

COLOGNE, Germany (DLR PR) — The Chang’e-4 lunar lander touched down on the far side of the Moon on 3 January 2019, with a German instrument for measuring space radiation on board. Since then, the Lunar Lander Neutron and Dosimetry (LND) instrument has been measuring temporally resolved cosmic radiation for the first time.

Earlier devices could only record the entire ‘mission dose’. In its current issue, the scientific journal  Science Advances reports on the work of the international group of scientists involved with the LND, including researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). Their investigations have involved more precise radiation measurements on the Moon.

MUNICH, Germany (DLR PR) — Almost all satellites are powered by solar cells – but solar cells are heavy. While conventional high-performance cells reach up to three watts of electricity per gram, perovskite and organic hybrid cells could provide up to 10 times that amount.

A research team from the Technical University of Munich (TUM) and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has now tested this type of cell in space for the first time.

PARIS (ESA PR) — The most sophisticated laser communication network ever designed has gained its second satellite.

The European Data Relay System (EDRS) was built to accelerate the flow of information from Earth-observation satellites to people on the ground.

The second satellite in the network, EDRS-C, has now passed its user commissioning review and entered into full service.

InSight Misson Logbook: Mars Mole Work Suspended for Now

The movement of sand grains in the scoop on the end of NASA InSight’s robotic arm suggests that the spacecraft’s self-hammering “mole,” which is in the soil beneath the scoop, had begun tapping the bottom of the scoop while hammering on June 20, 2020. (Credits: NASA/JPL-Caltech)

DLR Mission Update

In his logbook, Instrument Lead Tilman Spohn who is back in Berlin since April and communicating with JPL via the web, gives us the latest updates regarding the InSight mission and our HP3 instrument – the ‘Mole’ – which will hammer into the Martian surface.

Logbook entry 7 July 2020

On Saturday 20 June 2020 (Sol 557 on Mars), the team completed the ‘Free Mole Test’ announced in my previous blog post. The result was not quite what we had optimistically hoped for, but was also not entirely a surprise. The ‘Mole’ started bouncing in place after making some progress without direct support from the scoop on 13 June (Sol 550).

  • On 1 July 2020, the European Space Agency awarded contracts for the development and construction of six further Copernicus satellites.
  • Contracts with a value of more than 800 million euro are being awarded to space companies in Germany, a high percentage of which are SMEs.
  • The new satellites are intended to help find answers to the global challenges posed by climate change, population growth and environmental problems.

BONN, Germany (DLR PR) — Sentinel satellites are at the heart of Copernicus, Europe’s largest Earth observation programme. Sentinels are already reliably and continuously providing large amounts of data on the state of the climate, vegetation and oceans. Now, six more ‘Earth Guardians’, the High Priority Candidate Missions (HPCM), are being added.

ESA Moves Ahead on Low-cost Reusable Rocket Engine

PARIS (ESA PR) — ESA’s Prometheus is the precursor of ultra-low-cost rocket propulsion that is flexible enough to fit a fleet of new launch vehicles for any mission and will be potentially reusable.

At the Space19+ Council meeting in Seville, Spain last November, ESA received full funding to bring the current Prometheus engine design to a technical maturity suitable for industry. Developed by ArianeGroup, Prometheus is now seen as key in the effort to prepare competitive future European access to space.

Logbook entry 3 June 2020

More than three months have passed since my last blog post, when I had to report that the ‘Mole’ had unfortunately backed out again. Not as much as in October, but nevertheless, after going 1.5 centimetres into the surface, it reversed direction and backed out by 1.5 plus 3.5 centimetres, with the back cap ending a total of approximately five centimetres above the deepest position reached at the time and about seven centimetres above the surface. I described the situation in more detail in my previous post, in which I also detailed how the team attempted to explain the downward and then upward motion during one single hammering session (we had not seen this before).

  • DLR is building a new research observatory to determine the nature and trajectory of objects in low-Earth orbit quickly, precisely and reliably. Accurate data are important to avoid collisions between satellites and space debris.
  • Construction work will begin at the end of May 2020 at the Empfingen Innovation Campus in Baden-Württemberg. The inauguration is planned for spring 2021.
  • The project focuses on particularly accurate measurement of distances using specialised lasers.
  • The research telescope will be the largest of its kind in Europe.

Baden-Württemberg, Germany (DLR PR) — With the construction of a new research observatory, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is taking the next step in determining the nature and trajectory of objects in low-Earth orbit as quickly, precisely and reliably as possible. This is fundamental for the future of spaceflight as it is the only way to prevent collisions between objects such as space debris and active satellites.

Tests Start on 3D-Printed Thrust Chamber

LAMPOLDSHAUSEN, Germany (ESA PR) — Based on hot-fire tests of an Expander-cycle Integrated Demonstrator (ETID) that proved the technology and methods last year, ESA, ArianeGroup and DLR German Aerospace Center have built and hot-fire tested a fully additively-manufactured thrust chamber.

This first test lasted 30 seconds and was carried out on 26 May 2020 at the DLR German Aerospace Center’s Lampoldshausen testing facility. Additional tests are planned next week. The data from this test campaign will be collected and analysed.

This fully 3D-printed thrust chamber is built in just three parts and could power the upper stages of future rockets.

Additive layer manufacturing also known as 3D-printing, allows more complex designs for higher performance, vastly reduces the number of parts in this case from hundreds to three, and speeds up production time. This reduces costs and significantly improves the competitiveness of liquid propulsion engines for European launch vehicles.

This fullscale chamber has a 3D-printed copper liner with integrated cooling channels and a high-strength jacket built on via cold-gas spraying. Its manifold and single-piece injector head are also 3D-printed. 

The production and test of these parts has been performed within ESA’s Future Launchers Preparatory Programme.
