Most certainly ISRO must have gained a lot from previous mission whether succesful or failures and most certainly ISRO must have access to better technology. But that does not undermine the efforts of ISRO scientists.

You need to recall that China's mission failed in 2011, and read your arguments/nitpicking again. China's failure in 2011 simply implies that with all the advantages you mentioned, MARS mission is still a challange. And ISRO needs to be praised for what they achieved.

+ - Indian Spacecraft "Mangalyaan" Placed in MARS orbit

Submitted by William Robinson
William Robinson (875390) writes "The spacecraft called Mangalyaan (“Mar’s craft”) which was launched in November last year, slowed down just enough to touch the orbit early Wednesday (Indian Time), securing India a place in the elite global space club of Martian explorers. More than half of the 51 Mars missions launched globally have failed. India’s Mars entry is the fourth, after the United States, Europe and Russia. But India’s mission cost a fraction of NASA’s $670 million Maven which entered Mars on Sunday. The Curiosity Rover, which touched down on Mars in 2012, cost nearly $2 billion. By comparison, India’s $72 million Mars orbiter is the cheapest inter-planetary mission in the world."

+ - Mangalyaan's main engine test fired for 4 seconds.

Submitted by William Robinson
William Robinson (875390) writes "Before the spacecraft is scheduled to enter Mars orbit, Indian Space Research Organisation (Isro) scientists reignited the Mars Orbiter Mission spacecraft's main engine for four seconds as a trial. The liquid apogee motor (LAM) engine has been idle for about 300 days since the spacecraft left the Earth's orbit on a Martian trajectory on December 1, 2013. The short-duration test was to ensure that the engine is in good shape for the 24-minute crucial manoeuvre on Wednesday."

+ - Mangalyaan Gets Ready to Enter MARS Orbit

Submitted by William Robinson
William Robinson (875390) writes "India's Mars Orbiter Mission, known as Mangalyaan is now at a distance of just nine million kilometres from the red planet, and is scheduled to enter the orbit of Mars at 7.30 am on September 24. Mangalyaan was launched on 5th November 2013 by ISRO, presently busy planning to reduce the speed of the spacecraft through the process of firing the LAM engine and bring it to 1.6 km/sec, before it is captured by the planet's gravity."

+ - Snipping HIV-1 Out From Human Cells Achieved

Submitted by William Robinson
William Robinson (875390) writes "Scientists from Temple University School of Medicine have achieved a way to snip out the integrated HIV-1 genes for the very first time. They created molecular tools to delete the HIV-1 proviral DNA. When deployed, a combination of a DNA-snipping enzyme called a nuclease and a targeting strand of RNA called a guide RNA (gRNA) hunt down the viral genome and excise the HIV-1 DNA. From there, the cell's gene repair machinery takes over, soldering the loose ends of the genome back together – resulting in virus-free cells."

+ - Hunt for Gravitational Waves Begin as Black Hole Trio Discovered.

Submitted by William Robinson
William Robinson (875390) writes "Astronomers from Max Planck Institute for Radio Astronomy in Bonn, Germany, have discovered three closely orbiting supermassive black holes in a galaxy more than 4 billion light-years away. This is the tightest trio of black holes known to date. Researchers say the discovery will help astronomers hunt gravitational waves, the ripples in the curvature of spacetime that propagate as a wave, travelling away from the source."

Simple solution is to patch it although it might be harder on some devices.

Agreed.

I do welcome these kind of reports, because they will motivate procrastinating managers. I know managers having big 'change resistance', with simple arguments like "Does it affect us?". These kind of report does tell them why it is much better to act now.

+ - NASA Recreates Space Dust on Earth

Submitted by William Robinson
William Robinson (875390) writes "A team of NASA scientists has successfully replicated the process of formation of interstellar dust occurring in the atmosphere of a dying star in a specialized facility called the Cosmic Simulation Chamber (COSmiC). Scientists believe that dust grains are the building blocks of universe, enveloping dying stars and then getting eventually ejected into "interstellar medium lead" to be part of the formation of planet. During the COSmiC experiments, they could simulate gas-phase with high radiation environment by using cold argon gas filled with hydrocarbons sprayed into a vacuum, similar to the cosmic space that has average temperatures of less than negative 270 degrees Fahrenheit or about 100 degrees in Kelvin. The researchers formed and detected nanoparticles on the order of 10nm size grains varying from 100-500 nanometers and combined grains up to 1.5 micrometers in diameter"

+ - Columbus ship "Santa Maria" has been found near Haiti after 500 Years

Submitted by rtoz
rtoz (2530056) writes "The British Newspaper The Independent has reported that a team led by underwater archaeological explorer Barry Clifford found the wreck of the Christopher Columbus' flagship, the Santa Maria which sank in 1492.

"All the geographical, underwater topography and archaeological evidence strongly suggests that this wreck is Columbus’ famous flagship, the Santa Maria," said Barry Clifford.

Santa María was the largest of the three ships used by Christopher Columbus in his first voyage.

The Santa Maria was built at some stage in the second half of the 15 century in northern Spain’s Basque Country. In 1492, Columbus hired the ship and sailed in it from southern Spain’s Atlantic. After 37 days, Columbus reached the Bahamas. But after few weeks Santa Maria drifted at night onto a reef off the northern coast of Haiti and had to be abandoned."
