[vc_row][vc_column][vc_column_text]The Indian Space Research Organisation (ISRO) on Friday launched its 42nd Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Centre (SDSC) in Sriharikota. The PSLV-C40 successfully placed 31 satellites, originating from seven countries, in two different orbits in this single mission.

The mission was watched keenly following the failure of ISRO’s August launch when the heat shield of PSLV-C39 did not separate, as a result of which the satellites got trapped inside the heat shield and failed to deploy. It was only the second total failure of the PSLV in nearly 24 years: the PSLV-D1, in its maiden flight, had failed on September 20, 1993.

The C40 was launched from the First Launch Pad of the ISRO’s SDSC Srikarikota High Altitude Range at 9.29 a.m. Its primary payload was the fourth satellite in the advanced remote sensing Cartosat-2 series.[/vc_column_text][vc_raw_html]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[/vc_raw_html][vc_column_text]The Cartosat-2, whose imagery will be used to develop various land and geographical information system applications, weighs 710 kg and was to be placed in a circular polar sun synchronous orbit 505 km from Earth. The satellite’s design life is five years. The 30 co-passenger satellites together weigh 613 kg and the total weight of all the 31 satellites carried onboard was about 1,323 kg.

Of greater interest were the two other Indian satellites in the C40’s payload. Seen as technology demonstrators, they signify progress towards miniaturisation. The microsatellite is of the 100 kg class. “This is a technology demonstrator and the forerunner for future satellites of this series,” said ISRO.

The nanosatellite, named Indian Nano Satellite – 1C, is the third in its series; its predecessors were part of the PSLV-C37 launch of February 2017. The INS-1C, whose mission life is six months, carries the Miniature Multispectral Technology Demonstration payload from the Space Applications Centre. “With a capability to carry up to 3 kg of payload and a total satellite mass of 11 kg, it offers immense opportunities for future use,” said ISRO.

The other 28 satellites came from six countries and were launched as part of deals made by ISRO’s commercial arm Antrix Corporation Limited. Three of them were microsatellites while 25 were nanosatellites. There were 19 satellites from the United States and five from South Korea; UK, France, Canada and Finland had a satellite each within PSLV-C40.

The mission also marked the successful demonstration of the multi-burn technology, which ISRO takes lot of pride-in, as representatives from six foreign countries – Canada, Finland, France, Republic of Korea, UK and USA – looked on from the VIP box. While 30 of 31 satellites carried by PSLV were first launched into a 505 km polar Sun Synchronous Orbit (SSO), the Microsat built by ISRO was placed in a 359 km polar SSO after bringing down the orbital height by reigniting the fourth stage of PSLV twice. This complex technology offers distinctive advantage to India in attracting foreign clientele.

The launch also signified the national space agency’s foray into dynamic micro and nano satellite manufacturing market, reported The New Indian Express (TNIE). Quoting Tapan Misra, Director, Space Applications Centre (SAC), it said, “Having a large number of small satellites, instead of a few heavy ones, makes sense as they could cover the same piece of ground more frequently – say, every 15 minutes – for collecting imagery. This could spell a revolution in the way satellites are used – whether it is for helping fishermen to identify catches, keeping track of crops or detecting natural disasters like floods and earthquakes. Similarly, increasing miniaturisation in electronics makes redundant the use of heavy satellites for telecommunications and remote sensing. Smaller satellites deliver better coverage at a fraction of the cost.”

He said ISRO was looking at a major shift. “Our aim is to build heavier launchers and lighter payloads, which give us distinctive advantage in carrying capacity.” The launch is one of the initial steps towards achieving this goal.”[/vc_column_text][vc_column_text css=”.vc_custom_1515743965381{padding-top: 10px !important;padding-right: 10px !important;padding-bottom: 10px !important;padding-left: 10px !important;background-color: #cccccc !important;border-radius: 10px !important;}”]Ten big achievements of ISRO (compiled by HT):

Launching 104 satellites in a single mission, 2017: On February 15, 2017, ISRO garnered international attention when it launched 104 satellites using the PSLV and successfully managed to put these satellites into their desired orbit in one go. 101 were foreign satellites out of the 104 launched. It also included the Cartostat-2 series, India’s earth observation satellite.

Indian Regional Navigation Satellite System, 2016: The seven-satellite system created India’s very own satellite navigation system that could potentially offer services like terrestrial and marine navigation, disaster management, vehicle tracking and fleet management, navigation aide for hikers and travellers, visual and voice navigation for drivers. The launch of the 7th navigation satellite brought India much closer to the ‘GPS club’. Experts said an Indian-owned system will be particularly useful in times of war to gain positional accuracy.

Launching 20 satellites, 2016: Before it made the 104 satellite record, in June, ISRO launched 20 satellites in one mission, a personal best for the space agency. Apart from Isro’s own satellites and those built by university students in the country, the mission carried satellites from the US, Canada, Germany and Indonesia.

Reusable Launch Vehicle, 2016: In May, Isro successfully tested the Reusable Launch Vehicle — Technology Demonstrator (RLV-TD) that was built on a budget of Rs 95 crore. The winged flight vehicle — dubbed as India’s space shuttle — that glided back onto a virtual runway in the Bay of Bengal in a 10-minute mission was the first stage of a fully re-usable vehicle. A reusable launch vehicle can bring down launch costs by up to ten times.

Mangalyaan, 2014: India joined an exclusive global club when it successfully launched the Mars Orbiter Mission on a shoestring budget that was at least 10 times lower than a similar project by the US. Only the United States, Russia and Europe have previously sent missions to Mars, but what made India’s achievement stand out was that it succeeded on its first attempt, which even the Americans and the Soviets could not.

Chandrayaan, 2008: India’s first unmanned lunar probe was launched almost a decade ago and was a landmark in India’s space mission. ISRO joined an elite list of just six space organisations to send an orbiter to the moon. A Tricolour was hoisted on the moon but Isro lost contact with Chandrayaan soon after.

Polar Satellite Launch Vehicle, 1993: It was developed in the 1990s and has become the Indian space mission’s most reliable workhorse. The PSLV carried out its first mission in 1993 but its first successful outing was the next year. For the next 20 years, it launched various satellites for historic missions such as the Chandrayaan and Mangalyaan. PSLV remains a favourite among various organisations as a launch service provider and has launched over 40 satellites for 19 countries.

Indian National Satellite System (INSAT), 1983: Launched by ISRO, INSAT is a series of multi-purpose geostationary satellites. It helped with telecommunications, broadcasting, meteorology, and search and rescue operations. The satellites built a communication system all across Asia Pacific region. There are nine working satellites in the group.

Aryabhatta, 1975: The Aryabhata spacecraft that was named after the famous Indian astronomer was the country’s first satellite. It marked a milestone in India’s space programme because it was completely designed in the country and launched from a Russian facility in 1975. Known better by its popular name Insat, the system is a network of satellites that facilitates communications and broadcasting across the south Asian region. The first satellite in the series was placed into orbit in 1983 and ushered in a revolution in India’s television and radio broadcasting, telecommunications and meteorological sectors. Nine satellites are operational.[/vc_column_text][/vc_column][/vc_row]

WhatsApp to introduce Native File Sharing feature similar to Apple’s AirDrop

Users can choose to be visible to others without disclosing their phone numbers to people who are not their contacts.

Published

A Meta-owned messaging platform, WhatsApp is all set to introduce a new feature that allows Android users to share files with another user nearby. According to reports, the feature will be developed similar to Apple’s AirDrop.

The file sharing feature nearby is not currently available for beta testers. However, according to a report from WhatsApp feature tracker WABetaInfo, it seems that the feature will soon be introduced. The report reveals a screenshot that shows an option within the app stating, to share files with people nearby, along with a list of nearby users.

It is interesting to note that users can choose to be visible to others without disclosing their phone numbers to people who are not their contacts. In order to share files with other users, one needs to wait for nearby users to accept their request. The process involves a unique interaction, where nearby users can shake their device to receive incoming share requests. It is important to note that this feature is designed with end-to-end encryption to ensure user privacy.

In the upcoming update, WhatsApp is expected to introduce a nearby file-sharing feature. However, the current beta version for Android, which is 2.24.2.20, has addressed a camera issue. Some Android beta testers have reported difficulties in launching the camera within the app after the 2.24.2.13 update. Upon launching, users were presented with an error message that said, can’t start camera, please restart your device. This issue persisted even after restarting the device or relaunching the app.

The latest beta update of WhatsApp, located at 2.24.2.20, has fixed the camera bug. This allows users to launch the camera within the app and share photos and videos with their contacts without any interruptions. As WhatsApp continues its efforts to improve its features and address bugs, users can expect a better messaging experience on the platform.

Meesho online shopping app

Ahead of the festive season, e-commerce platform Meesho’s mega blockbuster sale is starting on Friday, October 6, 2023. The platform will provide a massive discount of up to 80 percent on different categories such as essentials, accessories, electronics, footwear, etc.

The blockbuster sale is scheduled to conclude on October 13, 2023. Notably, the Softbank backed e-commerce platform is starting its festive sale a day before Flipkart or Amazon’s festive sale goes live.  The e-commerce platform’s first mega blockbuster sale will sell more than 400 brands directly with the help of authorised partners on its digital store called Meesho Mall.

Reportedly, the platform also added over 50 lakh new customers during these sales. More than 75 percent of the demand was received from Tier-II cities, including Amravati, Aurangabad, Dehradun, Nellore, Solapur, and Warangal. The platform further claimed that they have added more than 2 lakh sellers in the past two years.

Recently, Meesho affirmed that  they have received over 10 million (approx) from its pre-festive sales during Onam, Raksha Bandhan, and Ganesh Chaturthi. The platform has more than 14 lakh sellers, selling approx 12 crore products in 30 different categories. 

In an effort to increase the seller base, the company announced the onboarding of non-GST sellers on the platform earlier this week. The GST council announced to permit the e-commerce platform to onboard sellers with turnover of up to Rs 40 lakh.

Prior to Meesho’s Mega Blockbuster Sale, the company introduced a loyalty programme during which eligible users will earn Smart Coins, which the user can redeem every time they make the purchase of any products on the platform. 

As per Redseer, over 140 million shoppers are likely to make purchases during the festive season. This will enhance the Gross Merchandise Value (GMV) of the Indian e-commerce sector by 18 to 20 per cent and may touch Rs 90,000 crore as compared to Rs 76,000 crore last year.

Apple launched its most anticipated iPhone 15 series, including the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max during the Wonderlust event globally on September 12 night.

The iPhone 15 series will be available in India from September 22 but iPhone lovers can also pre-order, starting from September 15 onwards.

People can buy a new iPhone 15 or upgrade it to the old one. There are five colours available for the people.  

According to reports, Apple has been manufacturing the iPhone 15 series in India and China. Apple has moved 7% of its iPhone production to India. Previously, India was not making the newest models. The Centre’s production-linked incentive (PLI) scheme for smartphones played a part in Apple moving its production to India.

The new iPhone 15 has been launched with the same starting price as its prototype, the iPhone 14. The 128GB variant is priced at Rs 79,900, while the 256GB variant costs Rs 89,900. For people who need more storage, the 512GB variant is available for Rs 1,09,900.

This latest iPhone series puffs a 6.1-inch display and comes in five different colours which are pink, yellow, green, blue, and black. While the design remains the same as the previous models, the iPhone 15 features a dynamic island notch instead of the usual notch, which was highly popular among the iPhone 14 Pro phones.

The camera part of the iPhone series has undergone significant upgrades, the new iPhone 15, with an enhanced 48-megapixel primary sensor replaces the 12-megapixel dual camera system which was available in the previous iPhone 14. This significant improvement promises better low-light photography and portrait shots.

The tech giant announced that the iPhone 15 has an all-day battery life, making it more convenient for users to go about their daily activities without worrying about their phone’s battery.

The iPhone 15 Pro models feature a lighter body and thinner bezels. The new AirPods Pro with USB-C charging case will support Lossless Audio with Apple Vision Pro.

Additionally, the iPhone 15 is powered by Apple’s A16 bionic processor, an upgrade from the A15 bionic chipset used in the previous iPhone 14 and iPhone 14 Plus models. The Pro models had the faster and better A16 chip, but now this feature is available in all iPhone 15 models.

The USB-C port on the standard iPhone 15 and iPhone 15 Plus remain limited to lightning speeds up to 480 Mbps. The iPhone 15 Pro and iPhone 15 Pro Max support USB 3 speeds up to 10 Gbps. People will need to buy a separate 1-meter Thunderbolt 4 Pro cable for Rs 5,724 or Rs 10,701 for the 1.8-meter cable to support faster speeds.

The dynamic island notch feature, which can adjust its size according to notifications, was widely discussed before the launch of the iPhone 15. This unique feature can now be available in all models of the phone.

Another important feature of the iPhone 15 is the shift to the USB Type C charging port. Apple has abandoned the lightning port in favour of the more commonly used USB Type C charging port. This means, there is no longer a need for a special iPhone charging cable to be carried around everywhere you go.
