China’s space agency said a core segment of its biggest rocket re-entered Earth’s atmosphere above the Maldives in the Indian Ocean and that most of it burned up early yesterday.
Harvard astrophysicist Jonathan McDowell, who tracked the tumbling rocket part, wrote on Twitter: “An ocean reentry was always statistically the most likely. It appears China won its gamble. But it was still reckless.”
People in Jordan, Oman and Saudi Arabia reported sightings of the Chinese rocket debris on social media, with scores of users posting footage of the debris piercing the early dawn skies over the Middle East.
Usually, discarded rocket stages re-enter the atmosphere soon after liftoff, normally over water, and do not go into orbit.
The official Xinhua news agency later reported that re-entry occurred at 10:24am Beijing time.
“The vast majority of items were burned beyond recognition during the re-entry process,” the report said.
Despite that, NASA Administrator US Senator Bill Nelson issued a statement saying: “It is clear that China is failing to meet responsible standards regarding their space debris.”
The roughly 30m-long rocket stage is among the biggest space debris to fall to Earth.
China’s space program, with its close military links, has not said why it put the main component of the rocket into space rather than allowing it to fall back to Earth soon after discharging its payload, as is usual in such operations.
The Long March 5B rocket carried the main module of China’s first permanent space station — Tianhe, or Heavenly Harmony — into orbit on April 29. China plans 10 more launches to carry additional parts of the space station into orbit.
An 18-tonne rocket that fell in May last year was the heaviest debris to fall uncontrolled since the former Soviet space station Salyut 7 in 1991.
China’s first-ever space station, Tiangong-1, crashed into the Pacific Ocean in 2016.
The Ministry of Transportation and Communications yesterday inaugurated the Danjiang Bridge across the Tamsui River in New Taipei City, saying that the structure would be an architectural icon and traffic artery for Taiwan. Feted as a major engineering achievement, the Danjiang Bridge is 920m long, 211m tall at the top of its pylon, and is the longest single-pylon asymmetric cable-stayed bridge in the world, the government’s Web site for the structure said. It was designed by late Iraqi-British architect Zaha Hadid. The structure, with a maximum deck of 70m, accommodates road and light rail traffic, and affords a 200m navigation channel for boats,
PRECISION STRIKES: The most significant reason to deploy HIMARS to outlying islands is to establish a ‘dead zone’ that the PLA would not dare enter, a source said A High Mobility Artillery Rocket System (HIMARS) would be deployed to Penghu County and Dongyin Island (東引) in Lienchiang County (Matsu) to force the Chinese military to retreat at least 100km from the coastline, a military source said yesterday. Taiwan has been procuring HIMARS and Army Tactical Missile Systems (ATACMS) from the US in batches. Once all batches have been delivered, Taiwan would possess 111 HIMARS units and 504 ATACMS, which have a range of 300km. Considering that “offense is the best defense,” the military plans to forward-deploy the systems to outlying islands such as Penghu and Dongyin so that
Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest foundry service provider, yesterday said that global semiconductor revenue is projected to hit US$1.5 trillion in 2030, after the figure exceeds US$1 trillion this year, as artificial intelligence (AI) demand boosts consumption of token and compute power. “We are still at the beginning of the AI revolution, but we already see a significant impact across the whole semiconductor ecosystem,” TSMC deputy cochief operating officer Kevin Zhang (張曉強) said at the company’s annual technology symposium in Hsinchu City. “It is fair to say that in the past decade, smartphones and other mobile devices were
‘CLEAR MESSAGE’: The bill would set up an interagency ‘tiger team’ to review sanctions tools and other economic options to help deter any Chinese aggression toward Taiwan US Representative Young Kim has introduced a bill to deter Chinese aggression against Taiwan, calling for an interagency “tiger team” to preplan coordinated sanctions and economic measures in response to possible Chinese military or political action against Taiwan. “[Chinese President] Xi Jinping [習近平] has directed the People’s Liberation Army to be ready to invade Taiwan by 2027. China has a plan. America should have one too,” Kim said in a news release on Thursday last week. She introduced the “Deter PRC [People’s Republic of China] aggression against Taiwan act” to “ensure the US has a coordinated sanctions strategy ready should
