Mare Serenitatis: crater statistics and lunar chronology

02.08.2006
This animated sequence, composed of three images taken by the advanced Moon Imaging Experiment (AMIE) on board ESA’s SMART-1 spacecraft, shows a portion of Mare Serenitatis on the Moon.

AMIE obtained the images on 18 March 2006 from distances between 1257 and 1213 kilometres from the surface, with a ground resolution ranging between 114 and 110 metres per pixel.

The imaged area is centred at about 21º East longitude and 18º North latitude, with a lunar field of view of 57 km. The Sun was on the West direction (top of this image) at about 50 degrees elevation.

Mare Serenitatis is one of the lunar maria, that are vast lava plains on the lunar surface. It formed between 3.9 and 3.8 thousand million years ago, a period in which the Moon was heavily bombarded by asteroids and the major impact basins on the Moon were formed.

This was followed by an episode of lunar volcanism that flooded the basin with basalt creating a fresh and flat surface.

To its southeast border, Mare Serenitatis lies close to Mare Tranquillitatis. Both maria were visited by previous lunar landers. In particular, Luna 21 and Apollo 17 (the last manned lunar mission to land on the Moon so far), landed on Mare Serenitatis in January 1973 and December 1972, respectively.
"Thanks to the solar elevation and SMART-1 camera resolution, the statistics of the sizes of the craters can be well determined in different units," says SMART-1 Project scientist Bernard Foing. "This permits us to establish a chronology, calibrated on absolute ages from isotopic measurements on returned lunar samples".

Im Focus: Neutron star merger directly observed for the first time

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...

Im Focus: Breaking: the first light from two neutron stars merging

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....

Im Focus: Smart sensors for efficient processes

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...

Im Focus: Cold molecules on collision course

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...

Im Focus: Shrinking the proton again!

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...
