India’s space agency wants to build a space station

9:28 am

The decline begins: The head of India’s space agency ISRO yesterday advocated that his country build its own space station.

The spacesuit is ready. A survival capsule is on the way. ISRO has everything to send astronauts into space and develop a space station, all that’s left is for the government to give the money and policy clearance, said ISRO chief AS Kiran Kumar here on Monday. “We have the capability to create a space station, but you (government) have to give us the money and time to make this happen,” Kumar told reporters on the sidelines of 34th foundation day celebration of the Raja Ramanna Centre for Advanced Technology (RRCAT). “If the government and country decides… we are ready. You need to provide us funding, policy clearance,” he said, adding that space mission is low priority for the government “because one doesn’t see any immediate use of this in country’s development and growth”.

Kumar’s comments came in the backdrop of Chinese media reacting to ISRO’s recent record launch of 104 satellites at one go. An editorial in a Chinese newspaper pointed out that “there is no Indian astronaut in space and the country’s plan to establish a space station has not started”. [emphasis mine]

Rather than focus on development that could increase India’s competitiveness in the profitable launch market, such as improving its rockets either by making them reusable or able to launch more frequently, Kumar instead wants to spend his government’s money and build a space station. He doesn’t really outline what he intends to accomplish with this station, other than demonstrate that India can match China. His focus instead is creating an infrastructure for pork and jobs for ISRO. The station will not bring in profits, which would be more useful to the country and its nascent private space industry.

This is what government agencies routinely do. They might start out functioning like an innovative private company trying to attract customers, but the lure of coerced government money always takes precedence in the end, and the agency shifts its focus to building pork-laden empires funded by tax dollars.

India preparing rover for 2018 Moon landing

9:18 am

The competition heats up: India preparing rover for 2018 Moon landing.

Isro’s Satellite Applications Centre Director, M. Annadurai, revealed the tentative launch schedule while speaking to the press at the Satish Dhawan Space Centre, Shar, Sriharikota on Wednesday. He said a Lander and a six-wheeled Rover were being prepped to go with the Chandrayaan-II mission. The chief scientist added that a launch is likely to take place in the first quarter of 2018. According to Dr P.V. Venkita Krishnan, the director of the Isro Propulsion Complex at Mahendragiri, engineers were currently testing soft-landing engines.

India’s launch of a record 104 satellites on a single rocket has pumped up the Indian press, as there were almost 20 stories on space and that launch in their press today, almost all favorable.

This article however is from the U.S., and takes a look at the ineffective American space policy that supposedly forbids American companies from launching on Indian rockets.

The U.S. Commercial Space Launch Agreement of 2005 prohibits the launch of commercial satellites on the Indian vehicle. The reasoning is that struggling U.S. commercial launch providers needed time to establish themselves in the market and would be wiped out by India’s PSLV, which is developed by the Indian Space Organization.

Since 2015, commercial satellite owners have successfully obtained waivers to the policy.

The article notes India’s competitive prices, as well as the overall state of the smallsat industry and its dependence on bigger rockets as secondary payloads to get into space. India’s rockets, funded and subsidized by the government but also built to be inexpensive so as to attract customers, is clearly positioned to effectively compete with SpaceX, who until now charged the least.

What will our Congress do? My preference would be for them to repeal this part of the 2005 law so that American satellite companies can fly on whoever they wish. That would increase competition but it would also likely invigorate the overall launch industry because it would increase the satellite customer base for those rockets and thus create more business for everyone.

Sadly, I suspect that Congress will instead demand that the waivers to the law cease, and will thus block the use if Indian satellites by American companies. The short-sightedness of our politicians never ceases to surprise me.

Countdown begins on India’s record-setting launch of 104 satellites

9:41 am

The competition heats up: ISRO has begun the countdown for Wednesday’s launch of India’s PSLV rocket, carrying a record-setting 104 satellites.

he Polar Satellite Launch Vehicle would be carrying a 714 kilogram main satellite for earth observation and 103 smaller “nano satellites” which would weigh a combined 664 kilograms. Nearly all of the nano satellites are from other countries, including Israel, Kazakhstan, The Netherlands, Switzerland, United Arab Emirates and 96 from United States, said the state-run ISRO.

If successful, India will set a world record as the first country to launch the most satellites in one go, surpassing Russia which launched 39 satellites in a single mission in June 2014.

Obviously, all these different satellites got a cut-rate launch deal by sharing the launch, which helps make their launch affordable. The disadvantage here is that they do not have much flexibility in choosing their orbits, which is why there is also a market now for small rockets aimed at launching single smallsats, such as Rocket Lab’s Electron.

An orbital change extends the life of India’s Mars orbiter

8:32 am

An orbital maneuver has allowed India’s Mars Orbiter Mission avoid an eight hour period with no sunlight — thus draining its batteries — so that the mission can be extended until 2020.

The on-board battery which was to take over had a life of just about 1.4 hours, while the eclipse was to last for 8 hours. The spacecraft’s future was bleak.

The scientists thought of a solution. On the night of January 17, a team of eight engineers at Indian Space Research Organisation’s Telemetry, Tracking and Command Network, Bengaluru, sent a time-delayed command to the Mars probe. The command set in motion firing of eight on-board thruster rockets. Each of them were fired for 431 seconds, pushing the Mars Orbiter Mission (MOM) space probe to a new orbit that completely avoids an eclipse up to September 2017. The shadowing in September is of a smaller duration, which the satellite’s batteries can handle. “Because of the crucial orbital change, the MOM now gets three additional years’ life. We are expecting it to transmit data till 2020,” Isro chairman A S Kiran Kumar told DH.

The mission’s science data is not as important as the experience it is giving Indian engineers in operating a planetary probe remotely from Earth. This success speaks well for the future of India’s space effort.

India to launch spare GPS satellite because of single satellite failure

8:42 am

Because of the failure of the atomic clocks on one of its GPS satellites have failed, India now plans to launch one of their spare satellites to increase the system’s redundancy.

The article does not say whether they will make any changes to the clocks on the spare satellite, which are the same as the failed clocks on the Indian satellite and were all built by the same European company that built the clocks on Europe’s Galileo GPS satellites that are also failing.

Clock problems on one of India’s GPS satellites

8:53 am

One of India’s seven GPS satellites is presently out of commission because its on-board atomic clock has malfunctioned.

The remaining satellites in the constellation is still functioning however, and are sufficient. The nature of this failure, so similar to the clock failures that have hit a number of Europe’s Galileo GPS satellites, makes me wonder if there is a connection.

India delays next launch of its largest rocket

6:44 am

India has delayed the next launch of its GSLV rocket from January to no earlier than March in order to conduct tests on the rocket.

This does not change the schedule for the next launch of their smaller PSLV rocket, which is still set for February and will launch a record of over a hundred satellites, most of which are smallsats.

Posted from Tucson Internationa Airport. I am heading to St. Louis today to give a lecture to the local chapter there of the AIAA.

Pakistan test fires a submarine-launched cruise missile

8:19 am

Does this make you feel safer? Pakistan last week successfully tested a submarine-launched cruise missile with a range of 300 miles and capable of carrying nuclear warheads.

The article provides a lot of detail not only on Pakistan’s capabilities but of India’s as well.

Although still a far cry from India’s 6,000 ton displacement Arihant class nuclear ballistic missile submarines (one is service and three others planned) and the short-range K-15 or medium-range K-4 ballistic missiles they carry, Pakistan’s nuclear armed Agosta class boats at least get the country in the second strike game, but in a very minimal way.

The Indian Navy’s anti-submarine capability is credible, and their submarine fleet includes multiple diesel-electric submarines of different origin, as wells a Russian Akula II class nuclear fast attack boat. So keeping an eye on Pakistan’s tiny Agosta 90B fleet will be possible, although it is not clear what level of confidence the Indian Navy has that they can always keep the boats in their own submarines’ crosshairs. Not just that, but even attempting to do so will tie up valuable assets that could better be assigned to deterring other regional nuclear powers, like China.

India considers going to Jupiter and Venus

9:39 am

The competition heats up: India’s space agency ISRO is considering unmanned missions to both Jupiter and Venus, while also delaying their first manned test flight four years until 2024.

More significant, the second link had this quote:

Mr Somnath said during the current fiscal, Isro planned eight PSLV flights, up from six in 2016. “Our aim is to steadily increase the launches between 12 and 20 in phases with creation of necessary infrastructure.

Like everyone else, they are getting enough business to up their launch rate. 2017 is going to be an active year in the launch market.

India hires private companies to build satellite

9:20 am

The competition heats up: For the first time India’s space agency ISRO has signed a deal with a private consortium of private companies to have them build satellites.

The contract signed on Friday includes assembly, integration and testing (AIT) of two spare navigation satellites consecutively in around 18 months. It was signed between M. Annadurai, Director of ISRO Satellite Centre (ISAC), and the consortium lead, Alpha Design Technologies P Ltd. ISAC assembles the country’s satellites for communication, remote sensing and navigation.

From the third year, Indian industry could expect competitive bids for a new lot of spacecraft of 300-500-kg class, perhaps five a year, for both ISRO and for export, Col. H.S. Shankar (retd), CMD of Alpha Design, told The Hindu. This is the first time that ISRO has outsourced an entire satellite to industry, said Col. Shankar .

The Modi government appears to be trying here to emulate NASA in putting private companies in charge of construction, rather than having things designed and built in-house by ISRO. This is a very good sign. If they do it now, in the early days of their space effort, they can reduce ISRO’s ability to grow into a large bureaucracy with its own vested interests.

Design flaw in India’s Mars Orbiter

8:52 pm

According to American researchers, a fundamental design flaw in the primary scientific instrument on India’s Mangalyaan Mars orbiter prevents it from carrying out its mission of measuring the methane in the Martian atmosphere.

“They did not design this properly for the detection of methane on Mars,” Michael Mumma, senior scientist at NASA’s Goddard Space Flight Center, told Seeker. In 2003, Mumma led a team that made the first definitive measurements of methane on Mars using an infrared telescope in Hawaii. The methane, which appeared in plumes over specific regions of Mars, reached a maximum density of about 60 parts per billion. “The (MOM) instrument is beautifully engineered, but not for the methane task. It has other value, but unfortunately they will not be able to provide measurements of methane at the levels needed to sample even the plumes we saw,” Mumma said.

They are re-purposing the instrument to measure the reflected sunlight coming off the Martian surface, useful data to be sure but hardly worth an entire space mission.

ISRO begins ground tests of its first lunar lander

9:36 am

The competition heats up: ISRO, India’s space agency, has begun testing the sensors its first lunar lander, Chandrayaan-2, will use to descend safely to the surface.

ISRO Satellite Centre or ISAC, which is the lead centre for the country’s second moon mission, has artificially created eight to ten craters to make the terrain resemble the lunar surface. This terrain is now the test bed for the lunar Lander’s sensors. Between Friday and Monday, a small ISRO-owned aircraft carrying equipment with the sensors flew a few times over these craters to see how well they performed.

PSLV places multiple satellites into different orbits

8:55 am

The competition heats up: India’s space agency ISRO has successfully used its PSLV rocket to launch eight satellites into two different orbits.

After the successful separation of SCATSAT-1, the PSLV-C35 mission continued. Still carrying the seven co-passenger satellites, the fourth stage of PSLV coasted over the South polar region and then started ascending towards the Northern hemisphere. A safe distance between the orbiting SCATSAT-1 and PSLV-C35 fourth stage was maintained by suitably manoeuvring the stage.

At 1 hour 22 minutes and 38 seconds after lift-off as the fourth stage was in the North polar region, the two engines of PSLV fourth stage were reignited and fired for 20 seconds. As a result of this, it entered into an elliptical orbit measuring 725 km on one side of the Earth and 670 km on the other. And 50 minutes later, as the PSLV fourth stage was again coasting near the south pole, its engines were fired for another 20 seconds. This second firing made the fourth stage to enter into a circular orbit of 669 km height inclined at an angle of 98.2 degree to the equator. 37 seconds later, the Dual Launch Adapter was successfully separated from the PSLV-C35 fourth stage. 30 seconds after this event, ALSAT-1N was the first co-passenger satellite to be separated successfully. Following this, the NLS-19, PRATHAM, PISAT, ALSAT-1B, ALSAT-2B, and Pathfinder-1 were separated from the PSLV fourth stage in a predetermined sequence thereby successfully completing PSLV-C35 mission.

This launch was also the 36th successful PSLV launch in a row.

India army suffers largest terrorist attack in decade

6:51 pm

Guess who: On Sunday seventeen India soldiers were killed by terrorists thought to come from a Islamic terror group based in Pakistan.

The Director General of Military Operations, Lieutenant General Ranbir Singh, said the terrorists were foreigners and there are clear signs of the role of the terror group Jaish-e-Mohammed, whose chief Masood Azhar is based in Pakistan. The group had been involved in the attack on Pathankot air base in January during which 7 army-men were killed.

An analysis of the situation can be read here.
