ISRO launches five British satellites in copy book style

Sriharikota (Andhra Pradesh), India successfully put into orbit five British satellites with its Polar Satellite Launch Vehicle’s XL variant (PSLV-XL) on Friday night in copy book style.

isroThis was the first commercial mission for ISRO in 2015. Exactly at 9.58 p.m., the PSLV-XL rocket, standing 44.4 meters tall and weighing around 320 tons, with a one way ticket tore into the night skies with fierce orange flames at its tail.

The expendable rocket carrying five British satellites cumulatively weighing around 1,440 kg as its luggage slung them into their intended orbit just over 19 minutes into its flight.

A.S. Kiran Kumar, ISRO Chairman, said: “An entirely successful launch for a customer. This time a set of new tool was developed. Five satellites were put into orbit for a customer.”

It was the heaviest commercial mission for the PSLV rocket till date though its total carrying capacity for such a mission is around 1,750 kg. The rocket blasted off from the first launch pad at the Satish Dhawan Space Centre here, about 80 km from Chennai.

For the onlookers, the rocket looked like an inverted flare/torch as it lit up the night sky amidst the cheers of the ISRO officials and the media team assembled at the rocket port here.

At the rocket mission control room, Indian space scientists at ISRO were glued to their computer screens watching the rocket escaping the earth’s gravitational pull.

Of the five British satellites, three are identical DMC3 optical earth observation satellites weighing 447 kg.

Of the other two satellites, CBNT-1 weighs 91 kg and also is an optical earth observation technology demonstration microsatellite, while the De-OrbitSail weighs 7 kg. This is an experimental Nano satellite for demonstration of large thin membrane sail and drag deorbiting.

Just over 17 minutes into the flight, the rocket started ejecting the DMC3 satellites one after another and they were followed by De-OrbitSail and CNBT-1 satellites.

The whole mission was completed just over 19 minutes into the flight as planned.

Immediately on the successfully ejection, scientists at the mission control center were visibly relieved and started clapping happily.

The three DMC3 and the CBNT-1 satellites are built by Surrey Satellite Technology Ltd. The De-OrbitSail is built by Surrey Space Center.

According to ISRO, the DMC3 constellation, comprising of three advanced mini-satellites DMC3-1, DMC3-2 and DMC3-3, is designed to address the need for simultaneous high spatial resolution and high temporal resolution optical earth observation.

Launched into a single low earth orbit plane and phased with a separation of 120 degrees between them, these satellites can image any target on the earth’s surface every day.

Major application areas include surveying the resources on earth and its environment, managing urban infrastructure and monitoring of disasters.

According to ISRO, accommodating the three DMC3 satellites each with a height of about three meters within the existing payload fairing or the heat shield of the PSLV was a challenge.

Thus, a circular L-adaptor and a triangular Multiple Satellite Adapter-Version 2 (MSA-V2) were newly designed and realized by ISRO for this specific purpose.

France’s SPOT 7 satellite weighing 714 kg was the heaviest single foreign satellite carried by a PSLV rocket till now. It was launched on June 30, 2014.

Meanwhile, ISRO is also readying for the launch of GSAT6 communication satellite using its heavier rocket Geosynchronous Satellite Launch Vehicle (GSLV).

The GSLV rocket’s first stage/engine has been assembled and the activities relating to that rocket assembly are progressing smoothly.

Only after the GSLV rocket launch the testing of a small model of reusable launch vehicle shaped like an aeroplane would be done, an ISRO official told IANS earlier.

Earlier, it was said the test reusable launch vehicle would happen in July.

Bengaluru, Oct 31: India will undertake another lunar expedition in early 2018 by sending a lander and a rover to explore the Moon to unravel its origin and present conditions, a top space official said on Monday.

The second Moon mission — Chandrayaan-2 — comes nearly a decade after India’s maiden lunar odessey in November 8, 2008, through a Polar Satellite Launch Vehicle (PSLV) rocket, which was launched on October 22 that year.

For launching Chandrayaan-1, the ISRO used PSLV rocket as the spacecraft carried only an impact probe vehicle to crash land on the Moon surface from its orbit.

“We are working towards putting an orbiter, lander, and the whole system in the lunar orbit in the first quarter of 2018,” state-run Indian Space Research Organisation (ISRO) Chairman A.S. Kiran Kumar told reporters here.

“The orbiter is getting ready and integrated,” he said.

“The lander and rover are undergoing tests. Some more tests are planned for December,” the ISRO chief said.

The lunar spacecraft will be launched onboard the space agency’s heavy rocket — Geosynchronous Satellite Launch Vehicle (GSLV) Mark II — from the second launch pad of the space port, located at Sriharikota in Andhra Pradesh.

As part of integration, the lander and rover would be configured for soft landing at a designated spot on the Moon and to conduct scientific experiments.

The rover will emerge from the lander to observe the lunar terrain and relay the data along with images through radio links.(IANS)

India to launch new Cartosat-2, 28 foreign satellites in December

India would launch its latest remote sensing satellite in Cartosat-2 series along with 28 foreign satellites riding piggy-back in December, a top space official said on Monday.

“In the next launch, we have a Cartosat along with 28 international commercial satellites, which we will launch in the second half of December,” said S. Rakesh, the Chairman and Managing Director of Antrix Corporation Ltd, the commercial arm of state-run Indian Space Research Organisation (ISRO).

There will be 25 nano satellites and three micro satellites from the US and other countries as co-passengers along the space firm’s own satellite of the Cartosat-2 series, he said.

The satellites will be launched into the orbit onboard the Polar Satellite Launch Vehicle (PSLV), Rakesh added.

The next launch will be keenly watched as it comes after ISRO’s PSLV rocket failed to deploy a spare navigation satellite on August 31. The rocket’s heat shield had failed to separate leaving the satellite inside the shield.

The Cartosat-2 is an earth observation satellite that is capable of providing high-quality images.

Imageries from Cartosat-2 series are used for cartographic, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, change detection to bring out geographical and man-made features and other Land Information System (LIS) and Geographical Information System (GIS) applications.

The previous satellite (Cartosat-2E) in the series was launched on February 15 this year from the spaceport at Sriharikota in Andhra Pradesh, about 90km northeast of Chennai.(IANS)

  • Union Minister of State (Independent Charge) for Atomic Energy and Space Dr. Jitendra Singh has announced the launch of the second mission to the moon, Chandrayaan 2, to be carried out in the first quarter of 2018.
  • ISRO Scientists have started their flight integration activities for its next lunar mission called as Chandrayaan 2.

Chandrayaan 2, India’s second mission to the moon, is an upgraded version of the previous Chandrayaan 1 mission launched nine years ago. This spacecraft is supposed to be a composite model comprising of orbiter, lander, and rover. According to ISRO, Chandrayaan 2 will land softly with the rover on the moon enhancing further scientific exploration on the lunar surface.

The minister even said India to have emanated as the world’s frontline nation in the field of Space Technology, at the annual inaugural session of the five-day Asian Conference on Remote Sensing. He referred to PM Narendra Modi’s efforts by appreciating the advancement in science and technology in the past three years where India had launched South Asian Satellite.

The 38th Asian Conference on Remote Sensing is ongoing in New Delhi from October 23 to 27.
