The Moon Impact Probe was dropped close to Shackleton crater, a place close to the south pole, where ice may exist in areas that are never illuminated by the Sun. It carried three instruments: a video imaging system, a radar altimeter and a mass spectrometer. The imaging system took pictures of the Moon as it approached the surface, the radar was used to determine the altitude, and the mass spectrometer was used to study the thin lunar atmosphere.
The probe was released from the spacecraft at 15:36 CET (20:06 Indian Standard Time), on 14 November and took 25 minutes to reach the surface. As it descended, the probe transmitted pictures to the orbiter that were later downloaded to Earth.
The Terrain Mapping Camera, TMC, and the Radiation Dose Monitor, RADOM, were functional by that time on the orbiter. After the impact of the probe, the remaining orbiter instruments were switched on consecutively for their commissioning activities.
During commissioning all standard operating modes of an instrument are exercised and the data and housekeeping parameters are examined to verify that everything is working properly.
The European near-infrared spectrometer SIR-2 was commissioned successfully on 19 November. The instrument was switched on and sent back housekeeping data indicating normal functionality. Science observations were started successfully on 20 November.
The Chandrayaan-1 X-ray Spectrometer, C1XS, was first activated on 23 November, and its commissioning is in progress.
The Sub-keV Atom Reflecting Analyser, SARA will be commissioned from 7 to 10 December. The commissioning for this instrument will take longer than usual because the instrument operates at a high-voltage, which will be increased in steps.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
