WASHINGTON, Feb 19 — NASA’s Perseverance rover touched down safely on Mars on Thursday, kicking off the agency’s ninth mission on the Red Planet, reports Xinhua news agency.
Cheers erupted in mission control at NASA’s Jet Propulsion Laboratory as controllers confirmed the rover, with the Ingenuity Mars Helicopter attached to its belly, completed its landing on Mars at around 3.55 pm local time.
The rover hit the top of the Martian atmosphere seven minutes before its touchdown, and executed the entry, descent, and landing (EDL) process, which was described by NASA as “seven minutes of terror.”
The Perseverance rover, which is the biggest, heaviest, cleanest, and most sophisticated six-wheeled robotic geologist ever launched into space, will search Jezero Crater for signs of ancient life on Mars, and collect samples that will eventually be returned to Earth.
It is the first rover to bring a sample caching system to Mars that will package promising samples for return to Earth by a future mission.
“Perseverance is NASA’s most ambitious Mars rover mission yet, focused scientifically on finding out whether there was ever any life on Mars in the past,” said Thomas Zurbuchen, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington.
“To answer this question, the landing team will have its hands full getting us to Jezero Crater – the most challenging Martian terrain ever targeted for a landing,” he said.
Perseverance is the fifth Mars rover sent by NASA to Mars, after Sojourner, Spirit, Opportunity, and Curiosity. It is also the largest and heaviest robotic Mars rover NASA has built.
The rover is the third spacecraft that arrived at the Red Planet this month after Hope probe, the first interplanetary mission from the United Arab Emirates (UAE), and Tianwen-1 probe, China’s first Mars mission.
Perseverance was launched on July 30 last year from the Space Launch Complex 41 at Cape Canaveral Air Force Station in the US state of Florida.
WhatsApp Introduces New Feature of Voice And Video Calls Using Desktop App
WhatsApp has recently decided to introduce the brand new feature of voice and also video calling just by using its own desktop app. According to a statement, WhatsApp stated that they are providing relief to countless of people that are sitting in front of computers who have had to reach for their phone every time their WhatsApp rang.
WhatsApp company said: “Throughout the last year, we’ve seen significant increases in people calling one another on WhatsApp, often for long conversations. Last New Year’s Eve, we broke the record for the most calls ever made in a single day with 1.4 billion voice and video calls”.
They also added, “With so many people still apart from their loved ones, and adjusting to new ways of working, we want conversations on WhatsApp to feel as close to in-person as possible, regardless of where you are in the world or the tech you’re using”.
Using the new feature by WhatsApp, users can answer on a much bigger screen through the desktop app which gives you the opportunity to see your family and loved ones clearly on a bigger canvas.

Other than that, the new feature will also allow you to resize the window on your computer screen and is set to stay on the top so you will never lose your video chats in a browser tab or stack of open windows. When you are in the website, WhatsApp will remind users that the voice and video calls on WhatsApp are end-to-end encrypted, so WhatsApp can never hear or see the conversations, regardless of whether you call from a phone or computer.
Please be reminded that the desktop calling feature is only available when the app is installed on your own computer. Desktop calling is also supported on Windows 10 64-bit version 1903 and newer as well as macOS 10.13 and newer.

Two Individuals Infected With Nigerian Covid-19 Variant In Malaysia Discovered – MOH

The detected cases are actually from two foreigners who just arrived in Malaysia from Dubai, United Arab Emirates. Both of them were found to be tested Covid-19 positive through the RT PCR Covid-19 swab test.
For a better recognition, The Institute for Medical Research (IMR) then performed a full genome sequencing as it takes into account both of the foreigner’s travel history. The Nigerian COVID-19 variant was first detected in the UK and also Nigeria in the month of December 2020.

MOH also stated that these discovered Nigerian variants can cause an increase in the likelihood as well as a possible decrease in the immune response. Worry not because MOH reassured that IMR and CPRC will continue to monitor the development of the virus mutation and to inform the public from time to time.
Other than that, they also reminded that even though the national immunization program is going smoothly, public health actions are still required as herd immunity has still not been achieved yet.

Food Waste: Amount Thrown Away Totals 900 Million Tonnes
AMMAN, March 5 — More than 900 million tonnes of food is thrown away every year, according to a global report.
The UN Environment Programme’s Food Waste Index revealed that 17 per cent of the food available to consumers – in shops, households and restaurants – goes directly into the bin, according to Petra.
Some 60 per cent of that waste is in the home.
The lockdown appears to have had a surprising impact – at least in the UK – by reducing domestic food waste.
