As the sun is steadily getting lower around the north pole of Mars, the Mars Phoenix Lander has managed to scoop soil into its sixth oven out of the eight that came with TEGA, the thermal and evolved-gas analyzer. Now there are two ovens left, and hopefully the lander will be able to make use of them before the sun drops below the horizon for the winter. Meanwhile, the lander would also serve as a weather station observing snow falling and clouds in the sky. And what is going on with the mystery of the unexpectedly dry Martian soil?
The Mars Phoenix Lander has a lidar used in meteorological research of Martian weather. A lidar is basically a radar which uses lasers instead of radio waves. It is used to study particles floating around the Martian atmosphere. It also gives an unintentional laser light show. While it's pretty bare-bones, it's somewhat awe-inspiring in that it's millions of kilometers away on another planet.
In other news, the lander has been able to get a tiny bit of water in the dirt sample that had previously been stuck on the scoop (apparently not all of the water ice sublimated away during the delay) and the Phoenix mission has been extended by 30 days, which gives extra time to fully utilize all of the ovens in the TEGA instrument and allows more extended observations of the weather changes near the Martian north pole. And there is also the good news that they won't have to worry about a possible short circuit dooming the mission as long as they don't overheat the instruments.
The Mars Phoenix Lander has finally managed to shake some Martial soil into its laboratory instrument. The TEGA, the laboratory instrument on the lander, has eight ovens for baking soil to analyze the ingredients. When the robotic arm scooped up soil to one of the ovens a few days ago, the soil got clogged on the screen over the oven, preventing analysis. They finally managed to unclog the soil after applying a new method of shaking the screen.
