Could the High-Energy Acoustic Event Above Kiev Have Been Russia's Acoustic Secret Weapon

On the evening of April 19, a "high-energy acoustic event" was recorded in Ukraine, according to the Main Center of Special Control. The center noted that the event was likely related to the entry of a cosmic body into the dense layers of the atmosphere, but the information is still being clarified. The estimated location of the epicenter of the explosion is believed to be in the Kyiv Region.

The Kyiv Regional Military Administration had previously warned about an air target over the Kyiv Region, and later, the Kyiv City Military Administration announced that a NASA space satellite had fallen to Earth.

However, the Alpha Centauri space education project believes that the green-glowing aerial object that fell to Earth was a meteorite, not a NASA satellite.

The Command of the Air Forces of the Ukrainian Armed Forces also stated that the flashes observed over Kyiv were likely related to the fall of a satellite or meteorite, but further investigation is still ongoing to determine the exact cause of the event.

Ukraine's State Space Agency reported a "high-energy acoustic event" at 9:57 pm, with the Kyiv Oblast at the center of the explosion.

The agency believes that the event is probably related to the entry of a space body into the dense layers of the atmosphere, and information is still being clarified.

Kyiv City Military Administration chief, Serhiy Popko, initially announced that the flash was the result of a NASA satellite crash landing on Earth. However, NASA spokesperson Rob Margetta stated that the RHESSI satellite, which was expected to re-enter Earth's atmosphere that day, was still in orbit when the phenomenon was visible over Kyiv.

The Alpha Centauri, a popular science channel, speculated that the object in the sky was a bolide, a type of meteor, and reported that the NASA satellite's orbit did not pass over Ukraine on the evening of April 19. NASA and the U.S. defense department are continuing to track the RHESSI satellite.

NASA has denied claims by Kyiv city authorities that a bright flash seen over Ukraine's capital was caused by its defunct satellite falling to Earth.

The head of the city's military administration had claimed that the flash was the result of the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) satellite's fall to Earth.

However, NASA stated that at the time of the flash, the satellite was still in orbit. RHESSI is one of many potentially hazardous pieces of space junk, and its possible debris field could fall over anywhere from southern South America to northern Africa, Central Asia, or China.

Many pieces of space debris are too small to monitor, but space agencies worldwide keep tabs on the over 30,000 largest pieces.

According to Yurii Ihnat, the spokesperson for the Air Force of Ukraine, the anti-air defence system was not operating in Kyiv Oblast during the flash in the sky on the evening of April 19.

Ihnat stated that the Air Force was countering Shahed drones on the eastern front at the time of the phenomenon, so it could not have caused the flash. He speculated that it was likely a meteor based on the previous reports of a "high-energy acoustic event."

Although an air-raid warning was issued due to the war in the country, the Air Force does not deal with space bodies, so they could not comment on any possible remains of the presumed meteorite.

Kyiv City Military Administration reported that they had initially believed the flash was caused by a NASA satellite falling, but it was later confirmed to be a meteorite.

The Main Special Control Centre of the State Space Agency of Ukraine reported a high-energy acoustic event during an explosion in Kyiv on April 19. The Kyiv City Military Administration has yet to receive an official statement from NASA.
