Voyager Probe 2 May Be Close to Interstellar Space: NASA

In May 2012, Voyager 1 experienced an increase in the rate of cosmic rays similar to what Voyager 2 is now detecting.

NASA’s Voyager 2 probe that was launched in 1977 has detected an increase in cosmic rays that originate outside our solar system, indicating that it is near the interstellar space.

Once Voyager 2 exits the outermost layer of the heliosphere — the vast bubble around the Sun and the planets dominated by solar material and magnetic fields — it will become the second human-made object, after Voyager 1, to enter interstellar space, NASA said in a statement on Friday.

Voyager 2 is little less than 17.7 billion km away from Earth — or more than 118 times the distance from Earth to the Sun.

It is the only spacecraft to visit all four giant outer planet — Jupiter (1979), Saturn (1981), Uranus (198 ) and Neptune (1989).

Voyager scientists have been watching for the spacecraft to reach the outer boundary of the heliosphere, known as the heliopause.

“We’re seeing a change in the environment around Voyager 2, there’s no doubt about that,” said Voyager Project Scientist Ed Stone from NASA’s Jet Propulsion Laboratory in Pasadena, California.

Since late August, the “Cosmic Ray Subsystem” instrument on Voyager 2 has measured about a five percent increase in the rate of cosmic rays hitting the spacecraft compared to early August.

The probe’s Low-Energy Charged Particle instrument has detected a similar increase in higher-energy cosmic rays.

“We’re going to learn a lot in the coming months, but we still don’t know when we’ll reach the heliopause. We’re not there yet — that’s one thing I can say with confidence,” Stone added.

Three other spacecraft are on interstellar trajectories. New Horizons is closing in on a Kuiper Belt Object more about a billion miles beyond Pluto on January 1, 2019.

Pioneer 10 and Pioneer 11 probes are no longer functioning, but will eventually travel into interstellar space.

In May 2012, Voyager 1 experienced an increase in the rate of cosmic rays similar to what Voyager 2 is now detecting.

“That was about three months before Voyager 1 crossed the heliopause and entered interstellar space,” said NASA. (IANS)

Apple’s Recycling Robot Is Capable of Disassembling 200 iPhones Per Hour

In 2018, the company refurbished more than 7.8 million Apple devices and helped divert more than 48,000 metric tons of electronic waste from landfills.

 Apple on Thursday announced to expand its global recycling programmes and introduced Daisy, its recycling robot that is capable of disassembling 200 iPhones per hour.

US customers can send their iPhones to be disassembled by Daisy which is 33 feet long, has five arms and can methodically deconstruct any of 15 iPhone models.

Daisy will disassemble and recycle select used iPhones returned to Best Buy stores throughout the US and KPN retailers in the Netherlands, the company said in a statement ahead of Earth Day that falls on April 22.

Apple also announced the opening of its “Material Recovery Lab” dedicated to discovering future recycling processes in Austin, Texas.

The Lab will work with Apple engineering teams as well as academia to address and propose solutions to today’s industry recycling challenges.

“Advanced recycling must become an important part of the electronics supply chain, and Apple is pioneering a new path to help push our industry forward,” said Lisa Jackson, Apple’s vice president of Environment, Policy and Social Initiatives.

Apple has received nearly one million devices through its programmes and each Daisy can disassemble 1.2 million devices per year.

In 2018, the company refurbished more than 7.8 million Apple devices and helped divert more than 48,000 metric tons of electronic waste from landfills.

Daisy can take apart iPhones to recover materials such as cobalt, aluminum and tin, which are then recycled back into the manufacturing process.

Once materials have been recovered by Daisy, they are recycled back into the manufacturing process.

For cobalt, which is a key battery material, Apple sends iPhone batteries recovered by Daisy upstream in its supply chain.

They are then combined with scrap from select manufacturing sites and, for the first time, cobalt recovered through this process is now being used to make brand-new Apple batteries. (IANS)
