UK scientists get a "whiff" of Titan’s surface

24.01.2005


Further insights into Titan were unveiled today (21st January 2005) as scientists involved in the joint NASA/ESA/ASI Cassini-Huygens mission presented further results and images a week to the day after the successful descent and arrival of the Huygens probe on the surface of Saturn’s largest moon.



Principal Investigator for the Huygens Surface Science Package [SSP], Professor John Zarnecki from the Open University, Milton Keynes, has spent the last week with his team analysing and interpreting the data.

Speaking at a press briefing from ESA’s Headquarters in Paris he said: “The Gas Chromatograph Mass Spectrometer has detected a ‘whiff’ of methane evaporating off the surface and the SSP data has also shown indications of gas flowing into its sensing area. These gaseous outbursts were released as heat generated by Huygens warmed the soil beneath the probe. This is a tantalising glimpse of the processes at work on Titan and shows how the weather systems operate with methane forming clouds and raining down on to the surface - producing the drainage channels, river beds and other features that we see in the images.


We are continuing to analyse the data from our penetrometer - the very first instrument to touch the surface of Titan - it then pushed through the crust to a depth of 10 to 15cm. Results indicate that beneath the thin crust lies a material with the consistency of sand or clay - but made of water ice grains rather than the rock grains that we find on Earth.”

Prof. Zarnecki added, “All of the instruments are producing intriguing results which, when combined, will begin to build a fascinating picture of this exotic World - with its unique geology, geography and even meteorology. The more we see the more there is to find out. We have only looked at a fraction of the data received - there is much more to study.”

After a 4 billion kilometre journey through the Solar System that lasted almost 7 years, the Huygens probe plunged into the hazy atmosphere of Titan at 10.13 GMT on 14th January 2005. It landed safely on the surface at 12.45 GMT with an impact speed of 5m per second. It continued transmitting from the surface for several hours, even after the Cassini orbiter dropped below the horizon and stopped recording data to relay back to Earth. The Surface Science Package of instruments on Huygens received 1 hour, 9 minutes and 36 seconds worth of data from the surface.

The science data received by Huygens will provide the vital ‘ground truth’ for the Cassini spacecraft as it continues its scientific observations of Titan during its 4-year tour of Saturn.

The Surface Science Package, designed and assembled in the UK (in partnership with ESTEC and SRC Warsaw), was the first part of the Huygens probe to make contact with Titan’s surface.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
