【欧空局公布了火箭发射十年后在轨道上解体的画面】欧洲航天局分享了迪莫斯天空调查上个月拍摄的碎片,其中估计有40到60件碎片,每个碎片的大小可能大于一英尺(30厘米)。与此同时,美国军方一名高级官员警告称,地球上最大的太空威胁之一,实际上可能是人类探索遗留下来的“垃圾”。科学家警告说,越来越多的碎片可能对未来的空间任务产生一系列不利影响。目前在地球轨道上运行的太空垃圾已经超过12000件,它们可能与重要卫星相撞,或干扰航天器的发射和着陆。

ESA releases footage of rocket's upper stage breaking apart in orbit a DECADE after launch as top U.S. military official warns space junk poses a serious threat to Earth

New footage of debris from an Atlas V Centaur rocket's upper stage soaring through space nearly ten years after its launch has highlighted the ever-growing concerns over space junk.

The European Space Agency today shared a look at the fragments captured just last month by the Deimos Sky Survey, revealing an estimated 40 to 60 pieces that could each be larger than a foot (30 cm) in size.

It comes as a top United States military official warned that one of Earth's biggest space-borne threats may in fact be the 'junk' left over from human exploration.

At a recent hearing on a proposal by President Donald Trump to establish a so-called Space Force, US Air Force Gen. John Hyten told officials that a growing amount of debris left to orbit Earth poses considerable risks and should be a major priority.

'I’ve advocated for a long time for the development of some kind of international norms and behaviors in space,' said Hyten, according to CNBC .

'And where those norms and behaviors should begin in my opinion is with debris. As the combatant commander responsible for space today, I don’t want more debris.'

The threat of space junk has come into full focus in recent years, as scientists and countries around the world begin to accelerate the launch of satellites and other orbitals that may be affected.

And, India's anti-satellite missile test last month has further pushed the issue into the spotlight.

This week, according to a recent announcement from the European Space Agency, debris from the late stage of a rocket was captured on video breaking into pieces, giving scientists a rare glimpse into how debris is formed.
