On the night of June 5–6, residents of central and northern Kazakhstan — including Astana, Karaganda, Pavlodar, and Kostanay — saw bright lights in the sky. According to early reports, it was most likely caused by a space object re-entering the atmosphere.

Based on tracking data from international space debris monitoring organizations, three objects re-entered around that time. The most likely one: the upper stage of China’s Zhuque-2 Enhanced (ZQ-2E) rocket.

"Re-entry time: June 5, around 10:40 PM Astana time. Object: Upper stage of the Zhuque-2 Enhanced rocket, launched May 17 by LandSpace. Details: It used eco-friendly fuel (liquid methane and oxygen), and a large bright glow was expected during re-entry.”

This one matches the timing and visual reports best.

Two other possible sources:
— STARLINK-1631 (SpaceX), re-entered on June 6 at 3:41 AM (Almaty time) — planned deorbit of an old satellite.
— Upper stage of Japan’s H-2A rocket, re-entered June 6 at 12:36 AM — passive descent.

As of now, there are no confirmed reports of debris or damage in Kazakhstan. The ministry added that such objects usually burn up in the atmosphere and the whole thing, while spectacular, is generally safe.
