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.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
In the fight against cancer, scientists are developing new drugs to hit tumor cells at so far unused weak points. Such a “sore spot” is the protein complex...
In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.
Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...
