Searching for water on the Moon: LZH develops laser for polar regions

17.12.2019

For a long time it was assumed there is no water on the Moon. However, evidence is increasing. The Laser Zentrum Hannover e.V. (LZH) is now working on the LUVMI-X project to develop a laser that can find water or other volatiles in the polar regions of the Moon.

The probability of finding water or other volatiles is highest in the polar regions, as they are frozen within the polar ice. To detect them, the LZH is developing a laser for a laser-induced breakdown spectroscopy (LIBS) system as part of the LUVMI-X project.


In the LUVMI-X project, the LZH is developing a laser that is resistant to cold for the search for volatile elements, such as water, in the polar regions of the Moon.

The laser radiation of the system breaks down molecules into their atoms. This creates a plasma and the atoms send out a characteristic spectrum. The spectrum of this plasma can then be compared with spectra of known atomic compositions to determine the elements in the sample.

In LUVMI-X the LZH, the Institute of Optical Sensor Systems of the German Aerospace Center (DLR) and OHB System AG jointly work on the LIBS system.

Goal: Reliable under extreme coldness
Such a laser must not only be small, compact, and robust, but also function reliably even in extremely cold areas with temperatures well below -100 °C. Such temperatures are problematic for conventional laser systems.

The finished system is to be tested by the DLR Institute of Optical Sensor Systems on regolith simulant, a substance that is very similar to Moon dust.

Of interest is, for example, how the plasma propagates in a vacuum and what parameters are necessary to make the measurement possible despite the difficult circumstances.

The low-temperature tests will be carried out by OHB System AG, which also develops the optical head of the instrument.

One of the objectives of the LUVMI-X project is a laboratory prototype for pre-testing. In the long term, the laser system is to be integrated into a moon rover. The development of this rover and other measuring instruments is also part of the research project.

The “Lunar Volatile Mobile Instrumentation Extended” project (LUVMI-X) is funded by the European Union within the scope of the Horizon 2020 funding program and coordinated by Space Applications Services NV / SA.

Im Focus: Harnessing the rain for hydrovoltaics

Drops of water falling on or sliding over surfaces may leave behind traces of electrical charge, causing the drops to charge themselves. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz have now begun a detailed investigation into this phenomenon that accompanies us in every-day life. They developed a method to quantify the charge generation and additionally created a theoretical model to aid understanding. According to the scientists, the observed effect could be a source of generated power and an important building block for understanding frictional electricity.

Water drops sliding over non-conducting surfaces can be found everywhere in our lives: From the dripping of a coffee machine, to a rinse in the shower, to an...

Im Focus: Blocking the Iron Transport Could Stop Tuberculosis

The bacteria that cause tuberculosis need iron to survive. Researchers at the University of Zurich have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport into the bacteria is inhibited, the pathogen can no longer grow. This opens novel ways to develop targeted tuberculosis drugs.

One of the most devastating pathogens that lives inside human cells is Mycobacterium tuberculosis, the bacillus that causes tuberculosis. According to the...

Im Focus: Physicist from Hannover Develops New Photon Source for Tap-proof Communication

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.

A 15-member research team from the UK, Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of...

Im Focus: Junior scientists at the University of Rostock invent a funnel for light

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.

The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
