China astronauts return as heroes

After making the country’s first spacewalk, three Chinese astronauts returned safely to Earth on Sunday. They landed in northern China’s Inner Mongolia region.

Mission commander Zhai Zhigang, 41, was watched on television by countless millions around the globe as his 15-minute spacewalk vaulted China into ranks of the United States and the former Soviet Union as the only nations to complete a spacewalk.

China sent its first man into space in 2003 and followed up with a two-man mission in 2005.

I have just gone through the press release from CERN. They said that investigations at CERN following a large helium leak into sector 3-4 of the Large Hadron Collider (LHC) tunnel have indicated that the most likely cause of the incident was a faulty electrical connection between two of the accelerator’s magnets. Before a full understanding of the incident can be established, however, the sector has to be brought to room temperature and the magnets involved opened up for inspection. This will take three to four weeks. Full details of this investigation will be made available once it is complete.

The time necessary for the investigation and repairs precludes a restart before CERN’s obligatory winter maintenance period, bringing the date for restart of the accelerator complex to early spring 2009. LHC beams will then follow.

Its a hot news now that famous theoretical physicist and the writer of award winning book ” Brief History of Time” Stephen Hawking may leave Cambridge. He has received an offer from Canadian research institute ” Perimeter Institute of Theoretical Physics” where he would join recently appointed director Neil Turok.
