Iran's space launch on Thursday failed to put its three payloads into orbit after the rocket was unable to reach the required speed, a defense ministry spokesman said in remarks carried on state television on Friday.

The attempted launch, which came as indirect US-Iran talks take place in Austria to try to salvage a 2015 nuclear deal, drew criticism from the United States, Germany and France.

"For a payload to enter orbit, it needs to reach speeds above 7,600 (meters per second). We reached 7,350," the spokesman, Ahmad Hosseini, said in a documentary about the launch vehicle broadcast on state TV and posted online.

On Thursday, Hosseini did not clarify whether the devices had reached orbit, but suggested the launch was a test ahead of coming attempts to put satellites into orbit.

Iran has suffered several failed satellite launches in the past few years due to technical issues.

Washington has said it is concerned by Iran’s development of space launch vehicles, and a German diplomat said Berlin had called on Iran to stop sending satellite launch rockets into space, adding that they violated a UN Security Council resolution.

France said on Friday the rocket launch aimed at sending three research devices into space violated UN rules and was "even more regrettable" as nuclear talks with world powers were making progress.

According to Reuters, Iran's foreign ministry rejected the US, German and French criticism of Tehran's launch of the satellite-carrying rocket.

"Scientific and research advances, including in the field of aerospace, are the inalienable right of the Iranian people, and such meddling statements will not undermine the Iranian people's determination to make progress in this field," it said in a statement carried by state media.

A UN resolution in 2015 "called upon" Iran to refrain for up to eight years from work on ballistic missiles designed to deliver nuclear weapons following an agreement with six world powers. Some states said the language did not make such a pledge obligatory.

Fire Tornadoes are a Risk Under California's Extreme Wildfire Conditions

As if they aren’t already facing enough, firefighters in California also could encounter fire tornadoes — a rare but dangerous phenomenon in which wildfires create their own weather.

The National Weather Service warned Tuesday that the combination of high winds and severely dry conditions have created a “particularly dangerous situation” in which any new fire could explode in size. The advisory, which runs into Wednesday, didn’t mention tornadoes, but meteorologist Todd Hall said they're possible given the extreme conditions.

 

A look at fire tornadoes according to The AP.

What is a fire tornado? Fire whirl, fire devil, fire tornado or even firenado — scientists, firefighters and regular folks use multiple terms to describe similar phenomena, and they don’t always agree on what’s what. Some say fire whirls are formed only by heat, while fire tornadoes involve clouds generated by the fire itself.

The National Wildfire Coordinating Group’s glossary of wildland fire terms doesn’t include an entry for fire tornado, but it defines a fire whirl as a “spinning vortex column of ascending hot air and gases rising from a fire and carrying aloft smoke, debris and flame,” and says large whirls “have the intensity of a small tornado.”

Wildfires with turbulent plumes can produce clouds that in turn can produce lightning or a vortex of ash, smoke and flames, said Leila Carvalho, professor of meteorology and climatology at the University of California, Santa Barbara.

“There is a rotation caused by very strong wind shear and a very hot, localized low-pressure system,” she said.

What is a fire tornado capable of? Fire tornadoes can make fires stronger by sucking up air, Carvalho said. “It creates a tornado track, and wherever this goes, the destruction is like any other tornado.”

In 2018, a fire tornado the size of three football fields killed a firefighter as it exploded in what already was a vast and devastating wildfire near near Redding, about 250 miles (400 kilometers) north of San Francisco in northern California. Scientists later described an ice-capped cloud that reached 7 miles (11 km) into the air and caused winds up to 143 mph (230 kph).

Research also suggests fire tornadoes can carry airborne embers, also called firebrands, over long distances, said James Urban, an assistant professor in the Department of Fire Protection Engineering at Worcester Polytechnic Institute. They also can change the fire’s behavior, he said.

“That’s also something that is dangerous and scary for first responders, or really anyone,” he said. “It can change and maybe go in a different direction.”

The interaction between wind, the fire plume and topography determines whether a tornado will develop, he said. For example, sometimes a certain topography will restrict airflow in such a way that a spiral pattern develops.

Can you make one in a lab? Together with San José State University, Worcester Polytech is part of a Wildfire Interdisciplinary Research Center. In the lab in Worcester, researchers have created small fire tornadoes by putting up walls around a fire or arranging a bunch of little fires that together restrict airflow. But that’s on a much smaller scale than what’s happening with the wildfires.

“We’ve got the biggest fire lab in the US for a university, but we cannot get something the size of what’s been reported at these fires,” he said. “You can’t really bottle that and put it in a lab.”
