CNN —Ukraine claims it has evidence Russia fired an advanced hypersonic missile – one that experts say is almost impossible to shoot down – for the first time in the almost 2-year-old war. The government-run Kyiv Scientific Research Institute of Forensic Expertise said in a Telegram post that debris recovered after a February 7 attack on the Ukrainian capital pointed to the use of a Zircon hypersonic cruise missile by the Russian military. Ukrainian authorities reported four people were killed and 38 others injured in Kyiv during the February 7 attacks, but no casualties have been directly attributed to the alleged Zircon missile. Its hypersonic speed makes it invulnerable to even the best Western missile defenses, like the Patriot, according to the United States-based Missile Defense Advocacy Alliance (MDAA). Additionally, the MDAA says the Zircon is “a maneuvering anti-ship hypersonic cruise missile” with a range of somewhere between 500 and 1,000 kilometers (310 to 620 miles).

Zircons Are Not the Gem You Probably Think They Are

If you could ask the humble zircon, the answer might be mistaken identity and decades of undeserved obscurity. In the Victorian era, the peak of popularity for zircons, a mined mineral, colorless ones were regularly used as diamond alternatives and blue ones were particularly popular. “Zircon can come in a wide range of colors — blue, yellow, brown, green and, rarely, a purplish-pink color,” said Nathan Renfro, senior manager of colored stone identification at the Gemological Institute of America. Then, along came cubic zirconia, an inexpensive synthetic crystal discovered in the 1930s but not developed to the point it could be faceted until 1969. By the end of the 1970s, it bypassed zircon and became the most common diamond simulant.

A half century later, crystals of the mineral zircon inside a coarse-grained igneous rock fragment collected by Schmitt are giving scientists a deeper understanding about the moon's formation and the precise age of Earth's celestial partner. This blasted magma - molten rock - into space, forming a debris disk that orbited Earth and coalesced into the moon. "I love the fact that this study was done on a sample that was collected and brought to Earth 51 years ago. "Interestingly, all the oldest minerals found on Earth, Mars and the moon are zircon crystals. The new study used atom probe tomography to determine there were no complications involving the lead atoms, confirming the age of the crystals.

Putin sends new hypersonic cruise missiles to Atlantic

MOSCOW, Jan 4 (Reuters) - Russian President Vladimir Putin on Wednesday sent off a frigate towards the Altantic and Indian oceans armed with new hypersonic Zircon cruise missiles which he said were unique in the world. "This ship, armed with 'Zircons', is capable of delivering pinpoint and powerful strikes against the enemy at sea and on land," Shoigu said. Shoigu said the hypersonic missiles, known as either Tsirkon or Zircon, could overcome any missile defence system. Russia, China and the United States are currently in a hypersonic weapons race. The target of a hypersonic weapon is much more difficult to calculate than for intercontinential ballistic missiles.
"This time the ship is equipped with the latest hypersonic missile system - 'Zircon'," said Putin. The weapons, Putin said, had "no analogues in any country in the world". Along with the Avangard hypersonic glide vehicle which entered combat duty in 2019, the Zircon forms the centrepiece of Russia's hypersonic arsenal. Shoigu said the hypersonic missiles could overcome any missile defence system. A U.S. Congressional Research Service report on hypersonic weapons says that Russian and Chinese hypersonic missiles are designed to be used with nuclear warheads.
