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.

Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...
Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
