ISRO gears up to launch five British satellites all together

Chennai: An Indian rocket is readying for its heaviest mission on July 10 to put into orbit five British satellites – all together – weighing around 1,440 kg from the space port in Sriharikota, the Indian space agency said Saturday.

According to the Indian Space Research Organisation (ISRO) its Polar Satellite Launch Vehicle (PSLV) is scheduled to carry aloft five foreign satellites on July 10.

The four stage/engine PSLV rocket in XL variant is expected to blast off at around 10 p.m. from the Sriharikota space centre in Andhra Pradesh around 80 km from here. The 62.5 hours countdown will start on July 8 at around 7.30 a.m.

Of the five, three are identical DMC3 optical earth observation satellites weighing 447 kg. These will be put into a 647 km sun-synchronous orbit.

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

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

According to ISRO, accommodating the three DMC3 satellites each with a height of about three metres 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 realised 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.

Stephen Hawking believes Technology could end Poverty and Disease, says Artificial Intelligence could be the Worst or Best things for Humanity

Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

Lisbon, November 7, 2017 : Technology can hopefully reverse some of the harm caused to the planet by industrialization and help end disease and poverty, but artificial intelligence (AI) needs to be controlled, physicist Stephen Hawking said on Monday.

Hawking, a British cosmologist who was diagnosed with motor neuron disease aged 21, said technology could transform every aspect of life but cautioned that artificial intelligence poses new challenges.

He said artificial intelligence and robots are already threatening millions of jobs — but this new revolution could be used to help society and for the good of the world such as alleviating poverty and disease.

“The rise of AI could be the worst or the best thing that has happened for humanity,” Stephen Hawking said via telepresence at opening night of the 2017 Web Summit in Lisbon that is attended by about 60,000 people.

“We simply need to be aware of the dangers, identify them, employ the best possible practice and management and prepare for its consequences well in advance.”

Hawking’s comments come during an escalating debate about the pro and cons of artificial intelligence, a term used to describe machines with a computer code that learns as it goes.

Silicon Valley entrepreneur Elon Musk, who is chief executive of electric car maker Tesla Inc and rocket company SpaceX, has warned that AI is a threat to humankind’s existence.

But Microsoft co-founder Bill Gates, in a rare interview recently, told the WSJ Magazine that there was nothing to panic about.

Stephen Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

“We need to take learning beyond a theoretical discussion of how AI should be, and take action to make sure we plan for how it can be,” said Stephen Hawking, who communicates via a cheek muscle linked to a sensor and computerized voice system.

“You all have the potential to push the boundaries of what is accepted, or expected, and to think big. We stand on the threshold of a brave new world. It is an exciting — if precarious — place to be and you are the pioneers,” he said. (VOA)

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)
