Mars under the spotlight again

14.03.2006


Relieved UK scientists are celebrating the news that NASA’s Mars Reconnaissance Orbiter (MRO) appears to have smoothly entered Mars orbit on Friday night (March 10th). Entering orbit is one of the most critical times for a space mission and Friday night’s manoeuvre managed to boost the tension for all as it took place on the far side of the Red Planet – so no news of the progress could be received on Earth during the critical phase.

UK scientists, from Oxford, Cardiff and Reading Universities are involved in the Mars Climate Sounder (MCS) instrument – essentially a weather station for Mars. It will profile the atmosphere of Mars detecting vertical variation in temperature, dust and water vapour concentration. Two previous versions of this instrument were lost with the ill-fated Mars Observer and Mars Climate Orbiter missions.

Professor Fred Taylor of Oxford University is delighted to have this nail-biting milestone out of the way. He says “Mars approach and orbit insertion is the most risky part of the mission. That is when we lost the last two spacecraft that were carrying our Climate Sounder instrument to Mars, in 1991 and 1999. Successfully achieving orbit this time means that we will be able to start taking some preliminary observations of the Martian atmosphere as early as 20th March.”



He adds “However, MRO will still be in a very elongated orbit then, and will not achieve the circular orbit from which we get the best observations for another six months. Changing the orbit involves the spacecraft dipping into the upper atmosphere of Mars at its closest approach each orbit, using the drag to reduce its speed a little at a time. This ’aerobraking’ is also a risky manoeuvre, but not as heart-stopping as arrival at Mars.”

The main aim of the MRO mission is to seek out the history of water on Mars. This will be accomplished by a suite of six science instruments, 3 engineering experiments and 2 science facility experiments. They will zoom in for extreme close up images of the Martian surface, analyse minerals, look for subsurface water, trace how much dust and water are distributed in the atmosphere and monitor the daily global weather.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
