NASA's next-generation Mars rover Perseverance blasted off from Florida's Cape Canaveral on Thursday atop an Atlas 5 rocket on a $2.4 billion mission to search for traces of potential past life on Earth's planetary neighbor.

The next-generation robotic rover - a car-sized six-wheeled scientific vehicle - also is scheduled to deploy a mini helicopter on Mars and test out equipment for future human missions to the fourth planet from the sun. It is expected to reach Mars next February.

It soared into the sky under clear, sunny and warm conditions carried by an Atlas 5 rocket from the Boeing-Lockheed joint venture United Launch Alliance. The launch took place after the Jet Propulsion Laboratory in California where its mission engineers were located was rattled by an earthquake, Reuters reported.

This marked NASA's ninth journey to the Martian surface. Perseverance is due to land at the base of an 820-foot-deep (250 meters) crater called Jezero, a former lake from 3.5 billion years ago that scientists suspect could bear evidence of potential past microbial life on Mars.

Scientists have long debated whether Mars - once a much more hospitable place than it is today - ever harbored life. Water is considered a key ingredient for life, and the Mars billions of years ago had lots of it on the surface before the planet became a harsh and desolate outpost.

One of the most complex maneuvers in Perseverance's journey will be what mission engineers call the "seven minutes of terror," when the robot endures extreme heat and speeds during its descent through the Martian atmosphere, deploying a set of supersonic parachutes before igniting mini rocket engines to gently touch down on the planet's surface.

Since NASA's first Mars rover Sojourner landed in 1997, the agency has sent two others - Spirit and Opportunity - that have explored the geology of expansive Martian plains and detected signs of past water formations, among other discoveries.

NASA also has successfully sent three landers - Pathfinder, Phoenix, InSight.



Sudan's Historic Acacia Forest Devastated as War Fuels Logging

Sudan's Historic Acacia Forest Devastated as War Fuels Logging

Vast stretches of a once-verdant acacia forest south of Sudan's capital Khartoum have been reduced to little more than fields of stumps as nearly three years of conflict have fueled deforestation.

What was once a 1,500-hectare natural reserve has been "completely wiped out", Boushra Hamed, head of environmental affairs for Khartoum state, told AFP.

Al-Sunut forest had long served as a haven for migratory birds and a vital green shield against the Nile's seasonal floods.

"During the war, Khartoum state has lost 60 percent of its green cover," Hamed said, describing how century-old trees "were cut down with electric saws" for commercial timber and charcoal production.

Where tall acacias once cast cool shade over a wetland just upstream from the confluence of the Blue and White Nile, barren ground now lies exposed, criss-crossed by people gathering whatever wood remains.

Hamed called it "methodical destruction", though the perpetrators remain unknown and there has been no investigation.

Similar devastation is unfolding across several regions -- including western Darfur, neighboring Kordofan and the central states of Sennar and Al-Jazirah -- as insecurity and economic collapse drive unchecked logging, according to Sudan's Forests National Corporation.

According to a 2019 study by the Nairobi-based African Forest Forum, Sudan had already lost nearly half of its forested land since 1960 due to agricultural expansion, firewood collection and overgrazing.

By 2015, the country ranked among Africa's least forested nations, with around 10 percent of its territory still covered by woodland, the study said.

The report had also warned of further degradation if reforestation and sustainable management efforts were not implemented -- concerns now compounded by the ongoing conflict.

- 'Barrier' -

Aboubakr Al-Tayeb, who oversees Khartoum's forestry administration, said the damage "affects not only Khartoum, but Sudan and the wider African continent."

"The forest was home to several migratory species from Europe," he told AFP.

More than a hundred bird species, including ducks, geese, terns, ibis, herons, eagles and vultures, had been recorded in the area, alongside monkeys and small mammals.

Al-Nazir Ali Babiker, an agronomist, said the loss of tree cover could cause more severe seasonal flooding because the "forest acted as a barrier" against rising waters.

Flooding strikes Sudan every year, destroying homes, farmland and infrastructure and leaving many families with no choice but to flee to safer areas.

The war in Sudan, which erupted in April 2023, has already killed tens of thousands, displaced 11 million and shattered critical infrastructure.

Before the fighting, forests supplied roughly 70 percent of Sudan's energy consumption, primarily through charcoal and firewood, according to data from the African Forest Forum.

Al-Sunut had also been a popular leisure spot for Khartoum residents.

"We used to come in groups to study and have a good time," recalls Adam Hafiz Ibrahim, a student at Omdurman Islamic University.

Today, wood gatherers have supplanted the usual walkers. Disregarding army notices alerting them to landmines, men and women traverse the dry, open ground that now stands where the ancient forest once grew.

"We're not cutting the trees. We just pick up whatever wood's already on the ground to use for the fire," said Nafisa, a woman in her forties navigating the dry grasslands.

"We found the trees down. We collect the wood to sell to bakeries and families," said Mohamed Zakaria, a construction worker who lost his job because of the war.

Experts say that the economic hardship caused by the war combined with a lack of enforcement has encouraged logging.

"The logging continues, because those responsible for forest protection cannot access many areas," said Mousa el-Sofori, head of Sudan's Forests National Corporation.

Efforts to replant acacias are underway, Tayeb of the Khartoum forestry administration said, but seedlings grow slowly and can take years to mature.

Restoring the lost woodlands would be "long and costly", said Sofori.

"Some of these forests were centuries old," he added.


Coffee Regions Hit by Extra Days of Extreme Heat, Say Scientists

The world's main coffee-growing regions are roasting under additional days of climate change-driven heat every year, threatening harvests and contributing to higher prices, researchers said Wednesday.

An analysis found that there were 47 extra days of harmful heat per year on average in 25 countries representing nearly all global coffee production between 2021 and 2025, according to independent research group Climate Central.

Brazil, Vietnam, Colombia, Ethiopia and Indonesia -- which supply 75 percent of the world's coffee -- experienced on average 57 additional days of temperatures exceeding the threshold of 30C.

"Climate change is coming for our coffee. Nearly every major coffee-producing country is now experiencing more days of extreme heat that can harm coffee plants, reduce yields, and affect quality," said Kristina Dahl, Climate Central's vice president for science.

"In time, these impacts may ripple outward from farms to consumers, right into the quality and cost of your daily brew," Dahl said in a statement.

US tariffs on imports from Brazil, which supplies a third of coffee consumed in the United States, contributed to higher prices this past year, Climate Central said.

But extreme weather in the world's coffee-growing regions is "at least partly to blame" for the recent surge in prices, it added.

Coffee cultivation needs optimal temperatures and rainfall to thrive.

Temperatures above 30C are "extremely harmful" to arabica coffee plants and "suboptimal" for the robusta variety, Climate Central said. Those two plant species produce the majority of the global coffee supply.

For its analysis, Climate Central estimated how many days each year would have stayed below 30C in a world without carbon pollution but instead exceeded that level in reality -- revealing the number of hot days added by climate change.

The last three years have been the hottest on record, according to climate monitors.

A dog decided he would bid for an unlikely Olympic medal on Wednesday as he joined the women's cross country team free sprint in the Milan-Cortina Games.

The dog ran onto the piste in Tesero in northern Italy and gamely, even without skis, ran behind two of the competitors, Greece's Konstantina Charalampidou and Tena Hadzic of Croatia.

He crossed the finishing line, his moment of glory curtailed as he was collared by the organizers and led away -- his owner no doubt will have a bone to pick with him when they are reunited.
