NASA's Phoenix Lander Has an Oven Full of Martian Soil

12.06.2008
"We have an oven full," Phoenix co-investigator Bill Boynton of the University of Arizona, Tucson, said today. "It took 10 seconds to fill the oven. The ground moved."

Boynton leads the Thermal and Evolved-Gas Analyzer instrument, or TEGA, for Phoenix. The instrument has eight separate tiny ovens to bake and sniff the soil to assess its volatile ingredients, such as water.

The lander's Robotic Arm delivered a partial scoopful of clumpy soil from a trench informally called "Baby Bear" to the number 4 oven on TEGA last Friday, June 6, which was 12 days after landing.

A screen covers each of TEGA's eight ovens. The screen is to prevent larger bits of soil from clogging the narrow port to each oven so that fine particles fill the oven cavity, which is no wider than a pencil lead. Each TEGA chute also has a whirligig mechanism that vibrates the screen to help shake small particles through.

Only a few particles got through when the screen on oven number 4 was vibrated on June 6, 8 and 9.

Boynton said that the oven might have filled because of the cumulative effects of all the vibrating, or because of changes in the soil's cohesiveness as it sat for days on the top of the screen.

"There's something very unusual about this soil, from a place on Mars we've never been before," said Phoenix Principal Investigator Peter Smith of the University of Arizona. "We're interested in learning what sort of chemical and mineral activity has caused the particles to clump and stick together."

Plans prepared by the Phoenix team for the lander's activities on Thursday, June
12 include sprinkling Martian soil on the delivery port for the spacecraft's Optical Microscope and taking additional portions of a high-resolution color panorama of the lander's surroundings.

The Phoenix mission is led by Smith with project management at JPL and development partnership at Lockheed Martin, located in Denver. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
