Falling Chinese rocket to crash to Earth on Saturday as US calls for ‘responsible space behaviours’ | Space

The White House has called for “responsible space behaviours” as a Chinese rocket, thought to be out of control, looks set to crash back to Earth on Saturday.

The US Space Command is tracking debris from the Long March 5B, which last week launched the main module of China’s first permanent space station into orbit. The roughly 30-metre (100ft) long stage would be among the biggest space debris to fall to Earth.

The non-profit, federally funded Aerospace Corp has said it expects the debris to hit the Pacific near the Equator after passing over eastern US cities. The orbit covers a swath of the planet from New Zealand to Newfoundland. The US defence department expects it to fall to Earth on Saturday though where it will hit “cannot be pinpointed until within hours of its re-entry”, the Pentagon said.

The White House press secretary, Jen Psaki, said on Wednesday: “The United States is committed to addressing the risks of growing congestion due to space debris and growing activity in space and we want to work with the international community to promote leadership and responsible space behaviours.”

China’s space agency has yet to say whether the rocket is being controlled or will make an out-of-control descent. But the Global Times newspaper, published by the Chinese Communist party, has claimed the rocket’s “thin-skinned” aluminium-alloy exterior will easily burn up in the atmosphere, posing an extremely remote risk to people.

Jonathan McDowell, astrophysicist at Harvard University, has predicted some pieces of the rocket will survive re-entry and that it would be the “equivalent of a small plane crash scattered over 100 miles”.

“Last time they launched a Long March 5B rocket they ended up with big long rods of metal flying through the sky and damaging several buildings in the Ivory Coast,” he said.

“What’s bad is that it’s really negligent on China’s part. Things more than 10 tonnes, we don’t let them fall out of the sky uncontrolled deliberately.”

The Long March 5B rocket carried the main module of Tianhe, or Heavenly Harmony, into orbit on 29 April. China plans 10 more launches to carry additional parts of the space station into orbit.

In May 2020 another Chinese rocket fell uncontrolled into the Atlantic off west Africa. It was the heaviest debris to fall uncontrolled since the former Soviet space station Salyut 7 in 1991.

China’s first space station, Tiangong-1, crashed into the Pacific in 2016 after Beijing confirmed it had lost control. In 2019 the space agency controlled the demolition of its second station, Tiangong-2, in the atmosphere.

In March debris from a Falcon 9 rocket launched by US company SpaceX fell to Earth in Washington and on the Oregon coast.
