India’s space program yesterday blasted off a spacecraft toward the center of the solar system, a week after the country’s successful uncrewed moon landing.
The launch of the Aditya-L1 was broadcast live shortly before midday, showing hundreds of spectators cheering against the deafening noise of the rocket’s ascent.

The mission is carrying scientific instruments to observe the sun’s outermost layers in a four-month journey.
The US and the European Space Agency (ESA) have sent numerous probes to the center of the solar system, beginning with NASA’s Pioneer program in the 1960s.
Japan and China have both launched their own solar observatory missions into the Earth’s orbit.

However, if the latest ISRO mission was to be successful, it would be the first by any Asian nation to be placed in orbit around the sun.
“It is a challenging mission for India,” astrophysicist Somak Raychaudhury told broadcaster NDTV on Friday.
Raychaudhury said the mission probe would study coronal mass ejections, a periodic phenomenon that sees huge discharges of plasma and magnetic energy from the sun’s atmosphere. These bursts are so powerful they can potentially reach the Earth and disrupt the operation of satellites.
Aditya-L1 can help predict the phenomenon “and alert everybody so that satellites can shut down their power,” he said. “It will also help us understand how these things happen, and in the future, we might not need a warning system out there.”
Aditya-L1 is to travel 1.5 million kilometers to reach its destination — still only 1 percent of the vast distance between Earth and the sun. At that point, the gravitational forces of both celestial bodies cancel each other out, allowing the mission to remain in a stable orbit around the sun.
Aditya-L1 would be traveling on the ISRO-designed, 320-tonne PSLV XL rocket that has been a mainstay of the Indian space program, powering earlier launches to the Earth’s moon and Mars. The mission aims to shed light on the dynamics of several other solar phenomena by imaging and measuring particles in the sun’s upper atmosphere.
BLOODSHED: North Koreans take extreme measures to avoid being taken prisoner and sometimes execute their own forces, Ukrainian President Volodymyr Zelenskiy said Ukrainian President Volodymyr Zelenskiy on Saturday said that Russian and North Korean forces sustained heavy losses in fighting in Russia’s southern Kursk region. Ukrainian and Western assessments say that about 11,000 North Korean troops are deployed in the Kursk region, where Ukrainian forces occupy swathes of territory after staging a mass cross-border incursion in August last year. In his nightly video address, Zelenskiy quoted a report from Ukrainian Commander-in-Chief Oleksandr Syrskyi as saying that the battles had taken place near the village of Makhnovka, not far from the Ukrainian border. “In battles yesterday and today near just one village, Makhnovka,
HOLLYWOOD IN TURMOIL: Mandy Moore, Paris Hilton and Cary Elwes lost properties to the flames, while awards events planned for this week have been delayed Fires burning in and around Los Angeles have claimed the homes of numerous celebrities, including Billy Crystal, Mandy Moore and Paris Hilton, and led to sweeping disruptions of entertainment events, while at least five people have died. Three awards ceremonies planned for this weekend have been postponed. Next week’s Oscar nominations have been delayed, while tens of thousands of city residents had been displaced and were awaiting word on whether their homes survived the flames — some of them the city’s most famous denizens. More than 1,900 structures had been destroyed and the number was expected to increase. More than 130,000 people
Some things might go without saying, but just in case... Belgium’s food agency issued a public health warning as the festive season wrapped up on Tuesday: Do not eat your Christmas tree. The unusual message came after the city of Ghent, an environmentalist stronghold in the country’s East Flanders region, raised eyebrows by posting tips for recycling the conifers on the dinner table. Pointing with enthusiasm to examples from Scandinavia, the town Web site suggested needles could be stripped, blanched and dried — for use in making flavored butter, for instance. Asked what they thought of the idea, the reply
US Secretary of the Treasury Janet Yellen on Monday met virtually with Chinese Vice Premier He Lifeng (何立峰) and raised concerns about “malicious cyber activity” carried out by Chinese state-sponsored actors, the US Department of the Treasury said in a statement. The department last month reported that an unspecified number of its computers had been compromised by Chinese hackers in what it called a “major incident” following a breach at contractor BeyondTrust, which provides cybersecurity services. US Congressional aides said no date had been set yet for a requested briefing on the breach, the latest in a serious of cyberattacks
