All 7 satellites launched in their precise orbits by ISRO’s old workhorse, the PSLV in its 16th launch is indeed praiseworthy.  The successor to the Oceansat-1,  is supposed to be the country’s second ocean studies satellite that aims to aid fishermen in identifying fishing zones and weathermen to forecast cyclones by measuring sea surface winds.

Along with the Oceansat-2, 6 nano satellites (4 CUBESATS and 2 RUBIN) were also launched.

CUBESAT-3: ITU-pSAT1, from Istanbul Technical University, Turkey
The primary mission of the satellite is to examine the performance of an on-board passive stability system consisting of a magnet which will align the satellite to the magnetic field of the Earth with an error of about 15 degrees according to simulations, and to verify this figure. A secondary objective is to download photographs taken using a camera with a resolution of 640 x 480 pixels

CUBESAT-4: SwissCube, from Ecole Polytechnique Fédéral de Lausanne, Switzerland
The SwissCube mission objective is to house a science payload and take optical measurements and characterize the airglow intensity over selected latitudes and longitudes thereby demonstrating that the airglow emissions are strong enough to be measured by an off-the-shelf detector and validating the concept for the development of a low-cost Earth sensor.

RUBIN-9
RUBIN-9 consists of two Spacecrafts Rubin-9.1 and Rubin-9.2 weighing 8kg each and will primarily be used for the Automatic Identification System (AIS) for Maritime applications. These are non-separable payloads that will be mounted at an angle of 45deg to the PSLV EB deck.

Rubin-9.1 is developed by Luxspace and has a mission objective of providing an insight into the issue of message collisions that limit detection in areas of dense shipping.

The main purpose of the Rubin-9.2 spacecraft is to test and qualify nano technologies from Angstrom company Sweden and to continue space based maritime Automatic Identification System (AIS) receiver experiments (started with Rubin-7 and Rubin-8 missions). Rubin-9.2 is similar to the Rubin-8 launched on PSLV-C9 in April 2008.

Posted by Liju Philip | Posted in India, israel, isro, military, pslv, science, space, spy, technology, World | Posted on 20-04-2009

The PSLV-C12, carrying 300-kg Radar Imaging Satellite (RISAT-2) and 40-kg Micro Satellite ANUSAT lifted off from ISRO’s Satish Dhawan space Centre here on Monday morning. At the end of the 48-hour countdown, the 44-meter tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

The Polar Satellite Launch Vehicle, weighing 230 tonnes at the time of launch, soared into a clear sky at 6.45am(local time) from the spaceport here, about 90 km north of Chennai. This is the 15th flight of ISRO’s workhorse PSLV, which had launched 30 satellites (14 for India and 16 for foreign countries) into a variety of orbits since 1993.

The launch vehicle carries two payloads – RISAT-2 (with all weather capability to take images of Earth) and ANUSAT (the first satellite built by an Indian University to demonstrate the technologies related to message store and forward operations).

The rocket would place both the satellites in their orbits around the earth shortly. The SAR, developed by Israel Aerospace Industries, gives RISAT defence capabilities.

ANUSAT is the first satellite developed by an Indian university (Anna University), which would demonstrate the technologies related to message storing and forward operations. University sources said scores of students and faculty from different streams had worked on this satellite for the last six years.

ANUSAT is a store-and-forward communication satellite that will help transfer confidential academic materials, including exam question papers, to prevent question paper leakages. It will also help monitor drought and wasteland, urban planning and other studies.

Moon Impact Probe reaches the moon

In a historic event, the Indian space programme achieved a unique feat today (November 14, 2008) with the placing of Indian tricolour on the Moon’s surface on Pandit Jawaharlal Nehru’s birthday. The Indian flag was painted on the sides of Moon Impact Probe (MIP), one of the 11 payloads of Chandrayaan-1 spacecraft, that successfully hit the lunar surface today at 20:31 hrs (8:31 pm) IST. This is the first Indian built object to reach the surface of the moon. The point of MIP’s impact was near the Moon’s South Polar Region. It may be recalled that the modern Indian space programme was initiated in 1962 when Pandit Jawaharlal Nehru was the Prime Minister of India.

Weighing 34 kg at the time of its launch onboard Chandrayaan-1, the box shaped MIP carried three instruments – a video imaging system, a radar altimeter and a mass spectrometer. The video imaging system was intended to take the pictures of the moon’s surface as MIP approached it. The radar altimeter was included to measure the rate of descent of the probe to the lunar surface. Such instruments are necessary for future lunar soft landing missions. And, the mass spectrometer was for studying the extremely thin lunar atmosphere.

chandrayaan-moon-probe

MIP’s 25 minute journey to the lunar surface began with its separation from Chandrayaan-1 spacecraft at 20:06 hrs (8:06 pm) IST. This was followed by a series of automatic operations that began with the firing of its spin up rockets after achieving a safe distance of separation from Chandrayaan-1. Later, the probe slowed down with the firing of its retro rocket and started its rapid descent towards the moon’s surface. Information from the its instruments was radioed to Chandrayaan-1 by MIP. The spacecraft recorded this in its onboard memory for later readout. Finally, the probe had a hard landing on the lunar surface that terminated its functioning.

Thus, India’s very first attempt to send a probe to the moon’s surface from its spacecraft orbiting the moon has been successfully concluded.

earth-from-chandrayaanWith the switching ON of two of Chandrayaan-1’s payloads – Terrain Mapping Camera (TMC) and Radiation Dose Monitor (RADOM) – on its journey to moon and with MIP’s successful impact on the lunar surface today, it is planned to switch ON and test the remaining eight payloads of the spacecraft in the coming few days.

It may be recalled that Chandrayaan-1 was successfully launched by PSLV-C11 on October 22, 2008 from India’s spaceport at Satish Dhawan Space Centre SHAR, Sriharikota into its intended initial elliptical orbit around the Earth. Following this, the spacecraft’s orbit was raised in steps and it was made to pass near the moon by repeatedly firing its 440 Newton liquid engine. After Chandrayaan-1’s entry into its planned lunar orbit on November 8, 2008, the orbital height was reduced in steps to its intended operational altitude of 100 km from the lunar surface.

moon-surfaceSince its launch, the health and orbit of Chandrayaan-1 is being continuously monitored from the Spacecraft Control Centre of ISRO’s Telemetry, Tracking and Command Network (ISTRAC) at Bangalore with critical support from antennas of Indian Deep Space Network (IDSN) at Byalalu. IDSN antennas have also received the images and scientific information gathered by TMC, RADOM, and more recently, by MIP.

pslv satellite

Other than a press conference and a brief note on the ISRO’s website, there doesnt seem to be much news about the Israeli spy satellite launch in the Indian papers. The Israeli papers are indicating that the satellite is meant to keep an eye on Iran.

India successfully launched an Israeli spy satellite into orbit in a boost to the South Asian nation’s efforts to win a share of the multi-billion-dollar space launch market.

The launch of the Tecsar satellite by an Indian-made rocket was carried out in clear weather at 9:15 am local time (0345 GMT) from the Sriharikota space station in southern India, the Indian Space Research Organisation said.

The 300-kilogram (650-pound) satellite, sometimes referred to as the Polaris, was steered into orbit about 20 minutes later, said Antrix Corporation, the marketing arm of the Bangalore-based space agency.

The satellite was designed and developed by MBT Space, a division of Israel Aerospace Industries. It is equipped with a camera that can see through clouds and carry out day and night all-weather imaging.

Posted by Liju Philip | Posted in environment, global warming, hydrogen, India, isro, space, tata, World | Posted on 25-11-2007

BMW already has it, so has Mercedes-Benz. The technology for a hydrogen car is already present in the market for years. But what needs to be studied is if the cost of a hydrogen car can be bought down to manageable levels. TATA Motors is already working on a Rs 1 lakh car (approx USD 2500). But does it have the technology to build a cheaper car, powered by hydrogen, for mass consumption is the crux of the matter. We do live in interesting times ;)

bmw hydrogen car

Automobile major Tata Motors and space agency Indian Space Research Organisation (ISRO) are gearing up to launch the prototype of the world’s cleanest car that will run on hydrogen and emit a mere wispy trail of water vapour. Making this announcement in Bangalore on Thursday, ISRO chairman Madhavan Nair said that the car would roll out early next year.Nair said that an agreement for the pilot project to see whether hydrogen can be used as fuel for automobiles had been signed and work had already commenced on the project. He said that ISRO is working with the Tatas and, if all goes well, the car will be rolled out in early 2008.

This car will have engine as it will be completely electricity-driven, and hydrogen and atmospheric oxygen will be combined in the fuel cell to produce electricity that will propel the car. The car will also have hydrogen storage and regulatory control systems, Nair added.
