After moon odyssey, it’s ‘Mission Sun’ for ISRO

Good Evening friends, something again I should take proude. After success of Chandrayaan-1, ISRO is planning for Mission Sun. Read the news below I found on ndtv website. After Chandrayaan-I moon odyssey, it’s in a way “Mission Sun” for team ISRO.

Scientists at the Indian Space Research Organisation are in an advance stage of designing a spacecraft, named ‘Aditya’, to study the outermost region of the Sun called corona. “That’s a mini satellite. In fact, the design is just getting completed,” ISRO Chairman G Madhavan Nair told a news agency. “During solar maxim…which is happening…we would like to see the type of emissions which are taking place in the Sun and how it interacts with the ionosphere and atmosphere and so on,” he said.

According to Dr Jayati Datta, Deputy Programme Director, Space Science Office, ISRO, Aditya is the first space based Solar Coronagraph intended to study corona. ‘Aditya’ would be the first attempt by the Indian scientific community to unravel the mysteries associated with coronal heating, coronal mass ejections and the associated space weather processes and study of these would provide important information on the solar activity conditions, she said. One has to go beyond the atmosphere to be able to mask the bright solar disc and study the corona. More…

 

“A basic understanding of the physical processes and continuous monitoring would help in taking necessary steps towards protecting ISRO’s satellites either by switching them off or putting them on a stand-by mode as warranted by the background conditions,” Datta Said. The temperature of the solar corona goes beyond million degrees. From the Earth, corona can be seen only during total solar eclipses mainly due to the bright Solar disc and the scattering of the sunlight by the Earth’s atmosphere.

Headphones affects heart devices

Good morning friends.

This news must give importance by every one.  Yes, we know children, teens or even adults are using headphones.  But they aqre not aware the disadvantage of that.  So I’d like to share with you what I have read in The Times of India.  It’s important.

Headphones from iPods or other digital music players may damage hearing, but music lovers who have a pacemaker or an implanted defibrillator are better off keeping them in their ears.

A small, new study revealed that placing the ubiquitous ear buds or other headphones to close to the chest could interfere with the proper functioning of the devices used to keep hearts beating at their proper rhythm.

Patients should not place the headphones, which contain magnets, in shirt pockets or drape them over their chest, lest they risk havoc with their heart-rhythm devices, researchers said on Sunday.

Pacemakers treat slow heart rhythms, while implantable cardioverter defibrillators (ICDs) jolt dangerously racing hearts back into a normal rhythm.

“For patients with pacemakers, exposure to the headphones can force the device to deliver signals to the heart causing it to beat without regard to the patients’ underlying heart rhythm,” said William Maisel of Beth Israel Medical Center in Boston and the study’s lead investigator.

Exposure of ICDs to magnets in headphones may deactivate them, causing the device to stop looking for abnormal heart rhythms, Maisel explained.

Results of the 60-patient study were presented at the American Heart Association scientific meeting in New Orleans. Researchers tested eight different models of MP3 player headphone with iPods. They found a detectable interference with the heart devices in 14 patients – 30 % of ICD patients and 15% of the pacemaker patients,
