India set to launch five British satellites

Chennai: The Indian space agency on Wednesday morning began the countdown for the July 10 rocket launch that would carry five British satellites.

According to Indian Space Research Organisation (ISRO), the 62 hours and 30 minutes countdown for the July 10th night launch of rocket Polar Satellite Launch Vehicle (PSLV) XL variant began at 7.28 a.m. on Wednesday.

The rocket is scheduled to blast off at 9.58 p.m. on July 10 from the first launch pad with five satellites together weighing around 1,440 kg, for an undisclosed fee.

Since 1999 India till date has launched 40 satellites of other countries and the successful launch of the five British satellites would take the tally to 45.

The 44.4 metre tall and weighing 320 tonne the PSLV is a four stage/engine rocket with six strap on motors for addition thrust during the initial phase of the flight.

The first and third stages are powered by solid fuel and are cast ready while the second and fourth stages are powered by liquid fuel which will be filled during the countdown.

Apart from fuelling up the engines, all the systems would be checked and rechecked during the countdown.

According to ISRO, this is the heaviest commercial luggage carried by a PSLV rocket till date.

Of the five British satellites, 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 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.

The total duration-from the rocket’s blast off to the fifth satellite separation- will be around 19 minutes 16 seconds.

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.

LG launches world’s 1st rollable TV for whopping Rs 64 lakh

LG Electronics on Tuesday released the world’s first rollable TV in South Korea at a jaw-dropping price of $87,000 (about Rs 63.9 lakh) as the tech giant aims to target high-end consumers amid the pandemic.

The company said overseas launch schedules of LG Signature OLED R have not been fixed yet due to the Covid-19 situation in each country, reports Yonhap news agency.

LG said the product, which uses flexible OLED display that leverages self-lighting pixel technology, is designed to deliver a differentiated user experience to high-end consumers and strengthen its position in the premium TV market.

Its name “R” contains the meaning of “revolutionary,” “rollable” and “redefine the space,” according to the home appliance maker.

The 65-inch TV model named RX is highlighted by its screen that rises from a box and can be rolled up inside.

Depending on how much the screen has rolled up inside the base, it provides three different viewing options for users to design interior space.

While the full view option is for watching TV, the line view option exposes only a part of the screen and offers five different stylish modes: music, clock, frame, mood and ThinQ home dashboard to check conditions of other smart devices inside the house.

The ‘Zero view’ completely hides the screen and allows it to be used as a Bluetooth speaker.

LG said it has adopted a differentiated system for its rollable TV from production to customer care service.

LG said production and quality inspection of the rollable TV will be processed by artisans and craftspeople at LG’s TV assembly line in Gumi, some 260 kilometers southeast of Seoul, a similar system used in making luxury cars and watches.
