In a two-for-one moonshot, SpaceX launched a pair of lunar landers Wednesday for US and Japanese companies looking to jumpstart business on Earth’s dusty sidekick.
The two landers rocketed away in the middle of the night from NASA’s Kennedy Space Center, the latest in a stream of private spacecraft aiming for the moon, The Associated Press reported. They shared the ride to save money but parted company an hour into the flight exactly as planned, taking separate roundabout routes for the monthslong journey.
It’s take 2 for the Tokyo-based ispace, whose first lander crashed into the moon two years ago. This time, it has a rover on board with a scoop to gather up lunar dirt for study and plans to test potential food and water sources for future explorers.
Lunar newcomer Texas-based Firefly Aerospace is flying 10 experiments for NASA, including a vacuum to gather dirt, a drill to measure the temperature below the surface and a device that could be used by future moonwalkers to keep the sharp, abrasive particles off their spacesuits and equipment.
Firefly’s Blue Ghost — named after a species of US Southeastern fireflies — should reach the moon first. The 6-foot-6-inches-tall (2-meter-tall) lander will attempt a touchdown in early March at Mare Crisium, a volcanic plain in the northern latitudes.
The slightly bigger ispace lander named Resilience will take four to five months to get there, targeting a touchdown in late May or early June at Mare Frigoris, even farther north on the moon’s near side.
“We don’t think this is a race. Some people say ‘race to the moon,’ but it’s not about the speed,” ispace’s founder CEO Takeshi Hakamada said this week from Cape Canaveral.
Both Hakamada and Firefly CEO Jason Kim acknowledge the challenges still ahead, given the wreckage littering the lunar landscape. Only five countries have successfully placed spacecraft on the moon since the 1960s: the former Soviet Union, the US, China, India and Japan.
“We’ve done everything we can on the design and the engineering,” Kim said. Even so, he pinned an Irish shamrock to his jacket lapel Tuesday night for good luck.
The US remains the only one to have landed astronauts. NASA’s Artemis program, the successor to Apollo, aims to get astronauts back on the moon by the end of the decade.
Before that can happen, “we’re sending a lot of science and a lot of technology ahead of time to prepare for that,” NASA's science mission chief Nicky Fox said on the eve of launch.
If acing their respective touchdowns, both spacecraft will spend two weeks operating in constant daylight, shutting down once darkness hits.
Once lowered onto the lunar surface, ispace’s 11-pound (5-kilogram) rover will stay near the lander, traveling up to hundreds of yards (meters) in circles at a speed of less than one inch (a couple centimeters) per second. The rover has its own special delivery to drop off on the lunar dust: a toy-size red house designed by a Swedish artist.
NASA is paying $101 million to Firefly for the mission and another $44 million for the experiments. Hakamada declined to divulge the cost of ispace’s rebooted mission with six experiments, saying it's less than the first mission that topped $100 million.
Coming up by the end of February is the second moonshot for NASA by Houston-based Intuitive Machines. Last year, the company achieved the first US lunar touchdown in more than a half-century, landing sideways near the south pole but still managing to operate.

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.”
