The competition heats up: After more than a decade of failed attempts, India has finally successfully launched its Geosynchronous Satellite Launch Vehicle (GSLV).
Moreover, this rocket was entirely built in India. It now gives that country a rocket competitive in the international communications satellite launch market.
The competition heats up: India has now set January 5 as the date for the test launch of its homebuilt powerful GSLV rocket.
India’s needs this more powerful rocket if they are going to be a serious player in the new colonial movement in space. They have had many problems over the past decade trying to get it operational. Maybe now they will finally succeed.
India has set January 5 as the launch date for its next attempt to launch is home-built GSLV rocket.
India’s Mangalyaan Mars probe successfully completed its first midcourse correction maneuver today.
As with the images the probe took of Earth, the success of this maneuver demonstrates the ability of the probe’s engineers to control, operate, and precisely point the spacecraft’s engine. It also proves that engine works as designed.
Here’s an interesting cultural tidbit: Of the 200,000 people who have applied to Mars One (see my previous post below) to go on its proposed one-way mission to Mars, India has the second most applicants after the U.S.
Mars One applicants come from over 140 countries; the largest numbers are from the US (24 per cent), India (10 per cent), China (6 per cent), Brazil (5 per cent), UK, Canada, Russia and Mexico (4 per cent), Philippines, Spain, Colombia and Argentina (2 per cent), and Australia, France, Turkey, Chile, Ukraine, Peru, Germany, Italy and Poland (1 per cent).
Welcome to the movies: The head of India’s research team at its Antarctica base has been recalled after he ordered the shut down of power at the station.
From October 7 to 12, ISRO’s satellite ground station at Antarctica, lost all transmission when its power supply was allegedly shut down by the team leader of the 32nd winter expedition to Bharati. The scientist, whose name was not revealed, has since been suspended and brought back to Goa. On October 14, NCAOR had also filed a police complaint against the scientist for the ‘wanton act of shutting down power’, said a statement released by the Ministry of Earth Sciences on Saturday.
This story had this tidbit:
It is believed the probe was ordered after the team leader allegedly ordered for the station’s power supply, which is obtained from diesel generators, to be cut off. A former chairman of ISRO, on the condition of anonymity, said: “If shortage of fuel was the issue, why would the ISRO station not take stock of fuel two months before it was to get exhausted and make arrangements for additional supply from South Africa? It is the most obvious thing to do. Unless there is some confusion or some issues, such a thing in Antarctica is unheard of. If power is switched off, people inside will freeze. So why was the power ordered to be cut off and why wait for diesel to get over?”
It also appears that three people are involved in this story, though details remain scant.
How India’s cryogenic rocket engine program was hampered and delayed, by the United States.
The article is fascinating, and rings very true until the last section. George Bush Sr. was an old CIA guy who distrusted the Soviets enough to want to prevent them from having any dealings with India, and Bill Clinton was very hostile to India during his entire administration. It is very easy to believe both presidents worked to stymie India’s efforts to work with the Russians.
India has delayed the first test launch of its Geosynchronous Satellite Launch Vehicle (GSLV) from mid-December until the first week in 2014.
This delay appears to be simple prudence. They have no specific deadline for launch, and by giving themselves a few extra weeks they can make sure they have things right. I also have two additional comments.
First, I wish they would give this rocket a decent name. GSLV is not only hard to remember, it is ugly. A better name would help their marketing enormously.
Second, read the comments at the link. They are all from Indians, and the majority of them are very enthused. It will give you a sense of that country’s passion for technology and science.
India’s first Martian orbiter, Mangalyaan, successfully fired its engines today to leave Earth orbit and head to Mars.
India’s Mangalyaan Mars probe has returned its first image, a picture of India on Earth.
Though you can always learn something from any image, what is significant here is that before even leaving Earth orbit engineers have proven that the spacecraft’s camera works.
A fourth engine burn has put India’s Mangalyaan probe back on course.
The unexpected abort during the previous burn occurred because engineers were testing the primary and secondary electrical coils that operate the engine’s valves.
During the firing on Monday morning, the team was trying to use both the primary and the redundant coils together as part of a trial. However, there was no fuel flow in this mode and the orbiter could not pick up the required velocity or reach the desired higher orbit. … A senior engineer involved in the process said, “Both the coils are working independently (but not if they are switched on together.)
Today’s burn demonstrated that nothing on the spacecraft has actually failed. As expected, simultaneous use of the two coils will no longer be attempted.
India’s Mars Orbiter Mission experienced its first technical problem during an engine burn today.
As scientists tried to increase the speed of the satellite as it orbited Earth Monday, the flow of fuel to the craft’s main engine stopped. Backup thruster engines kicked in to keep the speed up and help raise the spacecraft’s orbit, but the satellite’s incremental velocity dipped, the Indian Space Research Organisation said.
The spacecraft was unable to reach the desired orbiting height of 100,000 kilometers. The satellite is currently orbiting at just over 78,000 km above Earth and scientists have now altered the mission plan to include an additional engine firing Tuesday to help it reach the correct height and incremental velocity of 130 meters a second.
Engineers seem confident that the spacecraft’s back up systems will be able to pick up the slack.
Engineers successfully completed Mangalyaan’s second engine burn yesterday, raising its orbit to just under 25,000 miles.
Each one of these burns demonstrates the reliability of the spacecraft.
India’s Mangalyaan Mars probe has successfully completed its first orbital engine burn.
Not only was the burn successful, it demonstrated that the probe’s thrusters work as planned, which means it is almost certainly not going to be stranded in Earth orbit and will at least get to Mars.
The competition heats up: India successfully launched its first probe to Mars today.
The mission, also known in India as Mangalyaan (which means “Mars-craft”), has at the moment only reached Earth orbit. To get to Mars, it must still complete an additional engine firing on November 30.
India has begun the countdown for the November 5 launch of its first Mars orbiter.
Just today, spacetoday.com lists fourteen different stories in the Indian press about this mission, all enthusiastic, thus indicating the excitement in that country over space exploration and this mission in particular. Nor is this event unusual. I’ve noted before how space happy India is. They not only want to catch up and pass their neighbor China, they want to catch up with the United States and Russia. Should be fun to watch.
In preparation for November 5 launch of India’s first mission to Mars, ISRO successfully performed a full dress rehearsal countdown yesterday.
We all cross our fingers and wish India well on this mission.
The article also had this additional tidbit that reveals a great deal about world culture:

The complete failure of the fuel tank appears to be the cause of the massive leak that caused the launch postponement of India’s first home-made geosynchronous powered rocket in August.
Mr. Radhakrishnan [head of India’s space agency] said while the expert committee had attributed the fuel leak to stress corrosion cracking of the tank filled with propellants, exactly why this happened was “a research problem” that remains to be investigated. The next GSLV mission will switch to a better aluminium alloy material for its propellant tanks.
Up to now the reports have been somewhat vague about the cause of what was clearly an extensive leak. This story tells us that the tank essentially failed. As they filled it with propellants, cracks apparently showed up everywhere, with fuel spewing out in all directions. As far as I can remember, I don’t think there has ever been a rocket tank failure quite this spectacular.
This suggests there were fundamental design flaws in the tank or very serious quality control problems in its manufacture. With the next launch attempt scheduled for December 15, I hope India has identified the source of this incredibly basic problem and taken action to prevent it from happening again.
Update: Reader Patrick Ritchie found this older article which suggests the failed tank was an old tank of a design that was “prone for delayed cracks”. The error here then was in using this substandard old equipment rather than a newer tank.
A government official today unwittingly revealed a fundamental and unpleasant truth about how governments: operate. In an interview today, the head of India’s space agency denied that his country is in a space race with anyone.
Mr. Radhakrishnan, Secretary in the Department of Space and Chairman of Space Commission, said each country — whether it’s India, the US, Russia or China — had their own priorities.
“There is no race with anybody. If you look at anybody, they have their own direction. So, I don’t find a place for race with somebody. But I would say we are always on race with ourselves to excel in areas that we have chalked out for ourselves,” he told PTI here in an interview.
How typical. By denying the reality of the competition that India is part of Mr. Radhakrishnan illustrates for me and everyone once again the basic reason all government efforts eventually fail.

The competition heats up: India has mounted its first Mars probe on its rocket, readying it for a November 5 launch.
NASA and JPL have now stated that the government shutdown will not interfere with their promised support for India’s Mars Orbiter Mission.
Earlier reports had suggested that NASA’s Deep Space Network, used to communicate with planetary probes, would not be available because of the shutdown, and the mission would have to be delayed because of this.
