Nasa spacecraft ‘safe’ after closest-ever approach to Sun

National Aeronautics and Space Administration’s (Nasa) said on Friday that its Parker Solar Probe was “safe” and operating normally after successfully completing the closest-ever approach to the Sun by any human-made object.

The spacecraft passed just 3.8 million miles (6.1m km) from the solar surface on December 24, flying into the sun’s outer atmosphere called the corona, on a mission to help scientists learn more about Earth’s closest star.

The agency said the operations team at the Johns Hopkins Applied Physics Laboratory in Maryland received the signal, a beacon tone, from the probe just before midnight on Thursday.

The spacecraft is expected to send detailed telemetry data about its status on January 1, Nasa added.

Moving at up to 430,000 mph (692,000 kph), the spacecraft endured temperatures of up to 1,800 degrees Fahrenheit (982 degrees Celsius), according to the Nasa website.

“This close-up study of the Sun allows Parker Solar Probe to take measurements that help scientists better understand how material in this region gets heated to millions of degrees, trace the origin of the solar wind (a continuous flow of material escaping the Sun), and discover how energetic particles are accelerated to near light speed,” the agency added.

The Parker Solar Probe was launched in 2018 and has been gradually circling closer towards the sun, using flybys of Venus to gravitationally pull it into a tighter orbit with the sun.

Explainer: Iran’s economy faces rocky road amid rising prices, falling currency

Iran’s economy is going through one of its most difficult periods in years, fueled by sanctions, high inflation, and a significant drop in the value of the national currency, the rial. These pressures have had a direct impact on living standards and have also fueled recent protests. The protests began on Dec. 28 in commercial hubs in the capital Tehran, when shopkeepers, merchants, and small business owners staged strikes and demonstrations to protest soaring inflation, the collapsing rial, and deteriorating economic conditions, and have since grown into nationwide anti-government expressions of discontent involving workers, students, and others across multiple cities. The Iranian president said Sunday that his government is determined to address Iran’s economic problems amid the protests. Masoud Pezeshkian said the government admits to “shortcomings and problems” and is working hard to alleviate the people’s concerns, especially on the economy. Currency collapse at the centre of c...

Mitchell Starc surpasses Wasim Akram as most prolific left-arm pacer in Test history

Australian veteran Mitchell Starc became the most prolific left-arm paceman in Test history on Thursday, surpassing Pakistan great Wasim Akram. The 35-year-old bagged England’s Harry Brook at the Gabba in Brisbane on day one of the day-night second Ashes Test for his 415th wicket since his debut at the same ground 14 years ago. It moved him past Wasim, widely recognised as the greatest left-arm bowler the sport has seen. Wasim played 104 Tests for his 414 wickets with Starc reaching the milestone in his 102nd, helped by a career-best 7-58 in the first innings of the opening Ashes Test at Perth. Starc is now 16th on the all-time wicket-taker list and could move above both India’s Harbhajan Singh (417) and South Africa’s Shaun Pollock (421) in the current pink-ball Test. After that he will have New Zealand’s Richard Hadlee (431) in his sights. from Dawn - Home https://ift.tt/xclHiX2

Global reaction to potential Israel-Hezbollah ‘spiral of violence’

World leaders on Tuesday sounded the alarm over fears of a wider conflict after Lebanon suffered its deadliest day in two decades in Israeli air strikes on Hezbollah strongholds. After nearly a year of cross-border fire since the Gaza offensive erupted, Israeli bombardment on Monday killed 558 people in Lebanon, including 50 children, according to the country’s health ministry. The toll — the highest since Israel and Iran-backed Hezbollah went to war in mid-2006 — raised fears of an all-out conflict engulfing the Middle East. ‘Tens of thousands’ flee: UN UN Secretary-General Antonio Guterres was “gravely alarmed by the escalating situation… and the large number of civilian casualties, including children and women,” his spokesman Stephane Dujarric said. “Tens of thousands of people were forced from their homes yesterday and overnight, and the numbers continue to grow,” United Nations refugee agency spokesman Matthew Saltmarsh said in Geneva. ‘Spiral of violence’: US Israel’s clo...
