Here is the news.
A Chinese rocket start-up has successfully conducted its first sea recovery test.
of a verification rocket which descended vertically into waters off the coast of Shandong Province in eastern China.
During the test, the 26.8-metre-tall stainless steel rocket,
which had a diameter of 4.2 metres and weighed 57 tonnes at liftoff,
completed a 125-second flight,
reaching an altitude of approximately 2.5 kilometres during its full thrust ascent.
A video from the Beijing-based firm Space Epoch shows the rocket reigniting its engine during descent,
hovering above the sea surface and then landing softly in a vertical orientation.
Post-flight data analysis confirmed that the rocket performed normally throughout the test,
with experts declaring the sea landing recovery a success.
This is the latest effort by Chinese aerospace companies to develop reusable rockets.
In 2024, at least two domestic rockets,
including one developed by the Shanghai Academy of Spaceflight Technology,
completed 10-kilometre vertical take-off and landing tests in northwest China.
Chinese researchers have released a streamflow dataset of Tian Shan Mountains watersheds,
the key source region of Central Asian rivers.
The study, led by researchers from the Xinjiang Institute of Ecology and Geography,
under the Chinese Academy of Sciences, has been published in the journal Scientific Data.
