Thirty years after Apollo 16’s lunar module, Orion, landed at the western edge of the Descartes Mountains on 21 April 1972, there is still much that we don’t know about the Moon. For instance, how was it created? And what role did it play in the formation and evolution of Earth?
ESAs SMART-1: testing solar electric propulsion and studying the Moon
We may be closer to answering those, and many other questions, thanks to ESA’s mission to the Moon, known as SMART-1. Due to be launched early in 2003, the main purpose of the SMART-1 mission is to flight-test the new Solar Electric Propulsion technology – a kind of solar-powered thruster that is ten times more efficient than the usual chemical systems employed when travelling very long distances. If all goes well, such a system could be providing the propulsion system for future ESA missions into deep space, such as BepiColombo.
And, in the process, the mission will be providing some fascinating science. For instance, SMART-1 will be mapping the Moon more accurately than ever before, flying over all the Apollo landing sites. Thirty years ago, Apollo 16 carried six hand-held cameras to photograph the Moon’s surface. SMART-1 will be leading the way in the latest imaging techniques. Images taken from many different angles and X-ray and infrared detection work will allow scientists to draw up new three-dimensional models of the Moon’s surface.
SMART-1 will be looking at the darker parts of the Moon’s south pole for the first time. And it will be accurately mapping the Peak of Eternal Light, an eerie mountaintop that is permanently bathed in sunlight, while all around are dark craters never touched by the Sun. These craters are believed to harbour ice in the soil. SMART-1 will help scientists to understand if ice is present at the lunar poles.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
