When the Ariane 5 ECA qualification flight lifts off in October, one of the ‘passengers’ will be 33.5 litres of water. Onboard will be the experimental Sloshsat-FLEVO satellite, designed to help European scientists find out more about the movement of water in microgravity and its effects on satellites.
Sloshsat-FLEVO is aptly named: slosh for the movement of water, sat for satellite and FLEVO, the project’s acronym: Facility for Liquid Experimentation and Verification in Orbit. Flevo is also the name of the latest province in the Netherlands to be reclaimed from the sea, and one of the sites of the Dutch National Aerospace Laboratory (NLR), the main contractor for this project. The cube-shaped Sloshsat-FLEVO is a mini satellite with a mass of just 129 kg. It will be launched on top of the cylinder-shaped Maqsat-B2 structure and placed in the lower passenger position under the Ariane 5 fairing.
This joint project between ESA’s Technology Research and Development Programme and the Netherlands Agency for Aerospace, is funded mainly through ESA’s General Study and Technology Programme. Sloshsat is designed to investigate fluid dynamics in microgravity conditions by monitoring the behaviour of 33.5 litres of deionised water, placed in a tank onboard the small satellite.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...
The well-known representation of chemical elements is just one example of how objects can be arranged and classified
The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...
Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
