Concerns Over Debris Left By ASAT Missile Before ISRO’s April 1 Launch

Concerns Over Debris Left By ASAT Missile Before ISRO's April 1 LaunchISRO will launch the PSLV on April 1 carrying multiple payloads.NEW DELHI: 

Will India’s recent test of the anti-satellite (ASAT) missile endanger the launch of the Polar Satellite Launch Vehicle tomorrow? The anti-satellite weapon launched as part of Mission Shakti created a new debris pile some 300 kilometres above the Earth.

When the PSLV is launched from Sriharikota, it will have to traverse through that debris belt where there would be a risk of collision.

Using a new rocket part of the ballistic missile defence system on March 27, India shot down the over-700 kilogram MicroSAT-R satellite at an altitude of 300 kilometres, creating a debris pile of some 300 pieces.

The whole operation was completed in three minutes after the killer missile was launched from Dr Abdul Kalam Island off the coast of Odisha by scientists of the Defence Research and Development Organisation or DRDO.

The ASAT missile can bring an enemy nation to a halt by disrupting communication systems.

The big question that needs some introspection as the Indian Space Research Organisation (ISRO) gets ready for the PSLV launch is – what are the risks from this new debris that India itself has created? And does ISRO have a plan to mitigate this new threat?

Experts say that at 300 kilometres, the very high speed collision of two man-made objects would generate a lot of space debris and they would certainly come in the way of future launches at least for the next several weeks.

India is launching a satellite tomorrow, six days after the orbital collision. This too is another satellite belonging to the DRDO. Thus, there are concerns of whether the DRDO, by carrying out Mission Shakti, has endangered its own satellite called EMISAT.

“Yes, theoretically, that is right. But you should understand that today in space, millions of debris are floating around. Every satellite launch leaves anything between 100-150 fragments, they could be small bolts, they could be heat shields, they could be anything,” VK Saraswat, former DRDO head and member of the government think tank NITI Aayog told NDTV.

“These fragments keep floating around because as soon as you get out of atmosphere, nothing comes back; it always remains there and keeps on revolving because it is at the same speed of the satellite. So when they keep revolving they have a tendency to come in the way of other objects that are going to be propelled. That is why internationally there is a programme today to remove debris as much as possible and India is a signatory to that,” he said.

“Launching an anti-satellite missile does not create even 50 per cent of what we are doing while launching a large satellite, so it is not that we are going to increase by… suppose we have created 10 or 50 or 60 debris elements, one lakh or one million have become that much extra,” Mr Saraswat said.

On its part, before any launch, the ISRO does look out for space debris and on this occasion it would be more vigilant. “Collision avoidance is a standard procedure and on this launch at Sriharikota we will be extra cautious,” said Vivek Singh, ISRO assistant scientific secretary.

On several occasions when ISRO’s collision avoidance team has detected a threat of debris coming in the path of the rocket as it lifts off from Sriharikota, the launch has been postponed by a few minutes to ensure that the vehicle gets a clear path.

To track space debris, recently ISRO put in place a special multi-object tracking radar at Sriharikota. In addition, Indian space scientists depend on public domain information on space debris and situational awareness made available by the American armed forces.

Under normal circumstances, using these sophisticated radars the ISRO monitors space debris over the space port and on this occasion, sources say they are going to take abundant precautions.

Paytm Money claimed of registering over 1 million users within six months of launch.

Mutual fund investors putting their money via multiple channels including asset management companies, banks, advisors and distributors don’t get to look at the performance of their investments cohesively under a single platform.

Investors who haven’t invested via Paytm Money app can also track their daily portfolio performance irrespective of their channel or the mode of investment.

“We received many requests & feedback from Paytm Money users to be able to import their external investments to our platform. This assists an investor in keeping track of all investments in one place, further helping in their investment decisions,” said Paytm Money whole-time director Pravin Jadhav.

Paytm Money claimed to have partnered with 34 asset management companies covering over 94% AUM of the mutual fund industry.

Paytm’s mutual fund arm operates from Bengaluru and has a team of over 250 members Paytm Money, which aims to become a full-stack investment and wealth management services company, offer users mutual fund investments starting with Rs 100 via systematic investment plan or lump sum mode.

Recently at the World Economic Forum in Davos, Paytm’s chief financial officer said that the company is looking at expanding to 1-2 more developed markets this year. He told Reuters that the company has already found its footing in Canada and Japan while many of its commerce and financial services businesses have started to generate revenue and profits.

The company is also reportedly planning to expand into lending and credit cards services.

iPhone Slow: Apple Apologises Over Handling of Issue,

iPhone Slow: Apple Apologises Over Handling of Issue, Drops Price of Out-of-Warranty Battery Replacements

HIGHLIGHTS

  • Apple will offer battery replacements for $29, down from $79
  • Apple apologised over its handling of the issue
  • Will issue iOS update with greater battery life transparency

Facing lawsuits and consumer outrage after it said it slowed older iPhones with flagging batteries, Apple is slashing prices for battery replacements and will change its software to show users whether their phone battery is good.

In a posting on its website Thursday, Apple apologised over its handling of the battery issue and said it would make a number of changes for customers “to recognise their loyalty and to regain the trust of anyone who may have doubted Apple’s intentions.”

Apple made the move to address concerns about the quality and durability of its products at a time when it is charging $999 (roughly Rs. 64,000) for its newest flagship model, the iPhone X.

The company said it would cut the price of an out-of-warranty battery replacement from $79 (roughly Rs. 5,000) to $29 (roughly Rs. 1,850) for an iPhone 6 or later, starting next month. In India, the cost of out-of-warranty battery replacement was approximately Rs. 6,500 inclusive of taxes, as per industry sources. Apple has confirmed that the new price starting next month will be Rs. 2,000, exclusive of taxes. The company also will update its iOS operating system to let users see whether their battery is in poor health and is affecting the phone’s performance.

“We know that some of you feel Apple has let you down,” Apple said in its posting. “We apologise.”

On December 20, Apple acknowledged that iPhone software has the effect of slowing down some phones with battery problems. Apple said the problem was that aging lithium batteries delivered power unevenly, which could cause iPhones to shutdown unexpectedly to protect the delicate circuits inside.

That disclosure played on a common belief among consumers that Apple purposely slows down older phones to encourage customers to buy newer iPhone models. While no credible evidence has ever emerged that Apple engaged in such conduct, the battery disclosure struck a nerve on social media and elsewhere.

Apple on Thursday denied that it has ever done anything to intentionally shorten the life of a product.

At least eight lawsuits have been filed in California, New York, and Illinois alleging that the company defrauded users by slowing devices down without warning them. The company also faces a legal complaint in France, where so-called “planned obsolesce” is against the law.

Apple, Epson Face French Legal Complaints Over Allegedly Shortening Life of Products

Apple, Epson Face French Legal Complaints Over Allegedly Shortening Life of Products

HIGHLIGHTS

  • A French consumer association filed preliminary, legal complaints
  • Apple is already facing lawsuits in the US
  • Planned obsolescence is illegal in France

Smartphone maker Apple and Japanese printer company Epson are facing legal complaints in France over allegedly speeding up the ageing process of their products to stimulate demand.

A French consumer association called “HOP” – standing for “Stop Planned Obsolescence” – filed preliminary, legal complaints in court against the two groups over the charges.

HOP said it filed its complaint against Apple in Paris on Wednesday. A prosecutor opened an investigation into Epson last month, a judicial source said on Thursday, following a complaint filed in September by HOP in a court in the Paris suburb of Nanterre.

Laetitia Vasseur, co-founder of HOP, told Reuters the aim of both complaints was to apply the French consumer law, which was modified in 2015 to include the notion of planned obsolescence.

Apple is already facing lawsuits in the United States over accusations of having defrauded iPhone users by slowing down devices without warning to compensate for poor battery performance.

These lawsuits came after Apple said last week that operating system updates released since “last year” for the iPhone 6, iPhone 6s, iPhone SE and iPhone 7 included a feature “to smooth out” power supply from batteries that are cold, old or low on charge.

Phones without the adjustment would shut down abruptly because of a precaution designed to prevent components from getting fried, Apple said.

Under French law, companies risk fines of up to 5 percent of their annual sales for deliberately shortening the life of their products to spur demand to replace them.

A spokeswoman for Epson France said Epson denied the charges made against it by the HOP association. She added that Epson was working with authorities on the matter and that the quality of its products was of the utmost importance for the company.

Officials for Apple France could not be immediately reached for comment.
