Chandrayaan-1 now in lunar orbit

11.11.2008
Chandrayaan-1, the Indian Space Research Organisation’s (ISRO) lunar orbiter, was captured into orbit around the Moon on 8 November. One day later, the spacecraft performed a manoeuvre that lowered the closest point of its orbit down to 200 km from the Moon.

The spacecraft’s liquid-fuel propelled engine was fired at 12:21 CET (16:51 Indian Standard Time) when it was at a distance of about 500 km from the Moon.

This reduced the spacecraft’s velocity, enabling the Moon’s gravitational field to capture Chandrayaan-1 into lunar orbit. In this configuration, the orbit’s point closest to the lunar surface was at 504 km and the spacecraft circled the Moon in 11 hours.

This lunar orbit insertion manoeuvre was executed from the Chandrayaan-1 Spacecraft Control Centre at ISRO’s Telemetry, Tracking and Command Network at Bangalore. The performance of all the systems on board Chandrayaan-1 was registered as normal.

Yesterday, at 15:33 CET (20:03 Indian Standard Time), the spacecraft’s engine was fired for about 57 seconds, reducing the orbit’s point closest to the lunar surface to 200 km while the farthest point remained unchanged at 7502 km. In this elliptical orbit, Chandrayaan-1 takes about ten and a half hours to circle the Moon once.

Over the next few days, the height of the spacecraft’s orbit around the Moon will be carefully reduced in steps to achieve a final 100-km polar lunar orbit. The Moon Impact Probe (MIP) will then be released to hit the lunar surface, after which the other instruments on board will be turned on.

Chandrayaan-1 was launched on 22 October by from India’s spaceport at Satish Dhawan Space Centre SHAR, Sriharikota. The launcher placed the spacecraft in an elliptical orbit around Earth.

In the past two weeks, the Terrain Mapping Camera (TMC), one of the eleven scientific instruments of the spacecraft, was successfully operated twice to take pictures.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
