NASA's Mars rover captures film of a 'dust devil' on the Red Planet – Daily Mail

NASA’s Mars rover captures a faint almost ghostly ‘dust devil’ as it moves across the surface of the Red Planet

  • The Curiosity rover has been moving across the Gale crater on Mars since 2012
  • The crater is currently going through its windy season stirring up dusty soils
  • Heating surface caused a wind vortex that grabbed soil and created dust devils
  • One dust devil was captured on a series of images by the NASA Curiosity rover 

A new series of images sent to Earth by NASA‘s Curiosity rover on Mars show a spinning ‘dust devil’ as it skirts across the surface of the Red Planet.  

NASA Curiosity Rover has been moving across the Gale crater for the past eight years, conducting experiments and sending sending stunning still images to Earth.

Gale crater is going through its ‘windy season’, stirring up dust devils – caused by vortices of fast wind raising dust from the ground – captured by Curiosity. 

According to NASA researchers, being able to study weather phenomena on Mars that we can also see on Earth can help us understand seasons on the Red Planet. 

NASA hasn’t confirmed the size of the dust devil as it was too far away for accurate measurements, but orbiting spacecraft have seen some reaching 12 miles high.

It’s almost summer on Mars and because of this the surface of the Gale crater is heating up – this heating runs from early spring through to the Martian mid-summer.

When the surface warms enough, it causes convection and in turn vortices made up of fast winds that whip around low pressure cores – much like on Earth.

When the wind is strong enough – as has happened this year – they can pick up soil from the surface and create dust devils that can be seen across multiple still images sent back to Earth by the Curiosity rover.

‘We often have to process these images, by enhancing what’s changed between them, before dust devils clearly show up,’ wrote NASA scientist Claire Newman.

‘This dust devil was so impressive that – if you look closely – you can just see it moving to the right, at the border between the darker and lighter slopes, even in the raw images.’

Dust devils happen the same way on Earth as on Mars and form best when the terrain is relatively flat and dry and the air is warmer at the surface than above it. 

They are actually very common on Mars – but actually seeing on in motion is rare as they are relatively short-lived and Curiosity only sends back still images.

We know about them because Curiosity and orbiting spacecraft have spotted the tracks these dust devils leave behind them – rather than one in motion. 

To capture a dust devil movie the team had to get Curiosity to take a lot of images of the same region for between five and 30 minutes.

Then back on Earth the team worked to stitch the images together to creation a moving video that allowed them to track its path.

Monitoring their motion can provide information about a dust devil’s movement, where they initiate and how they evolve.

‘Looking at how fast they’re moving and in what direction also tells us about the background wind speed and direction at their location,’ said Newman. 

‘We also made sure to take meteorological measurements with throughout each movie, in case we image a vortex that’s close enough for us to also measure its pressure drop, impact on local temperatures, or even UV radiation if it’s dusty enough to partially block out the Sun.’

NASA has captured images of spinning dust devils on the Red Planet from space – but this is a still image rather than showing it in motion. This one reached 12 miles high

Dust devils also form on Earth. This is the moment a team of workers in Java, Indonesia, tried to ‘kill’ one with tools after it started wreaking havoc in the flour at a food processing plant

Monitoring dust devils isn’t the primary mission of the atmospheric team, their goal is to drill and sample material as part of a ‘wet chemistry’ experiment.

This involves transforming less volatile organic chemistry into forms that can be detected by the equipment onboard the Curiosity rover. 

While drilling and checking the samples, cameras on Curiosity could be used to monitor and capture images of the dust devil.

They also examined the dust seen above the rover in the crater. 

‘The dust measurements will help us to track the regional dust activity on Mars that has been seen from the surface and orbit in recent years,’ Newman wrote.

Curiosity is currently the only moving rover on the Red Planet, but Perseverance is currently in flight between the worlds and is due to land on Mars early in 2021.

THE NASA MARS CURIOSITY ROVER WAS LAUNCHED IN 2011 AND HAS IMPROVED OUR UNDERSTANDING OF THE RED PLANET

The Mars Curiosity rover was initially launched from Cape Canaveral, an American Air Force station in Florida on November 26, 2011. 

After embarking on a 350 million mile (560 million km) journey, the £1.8 billion ($2.5 billion) research vehicle touched down only 1.5 miles (2.4 km) away from the earmarked landing spot.

After a successful landing on August 6th, 2012, the rover has travelled about 11 miles (18 km). 

It was launched on the Mars Science Laboratory (MSL) spacecraft and the rover constituted 23 per cent of the mass of the total mission. 

With 80 kg (180 lb) of scientific instruments on board, the rover weighs a total of 899 kg (1,982 lb) and is powered by a plutonium fuel source. 

The rover is 2.9 metres (9.5 ft) long by 2.7 metres (8.9 ft) wide by 2.2 metres (7.2 ft) in height. 

The Mars curiosity rover was initially intended to be a two-year mission to gather information to help answer if the planet could support life, has liquid water, study the climate and the geology of Mars an has since been active for more than 2,000  days

The rover was initially intended to be a two-year mission to gather information to help answer if the planet could support life, has liquid water, study the climate and the geology of Mars.  

Due to its success, the mission has been extended indefinitely and has now been active for over 2,000 days.

The rover has several scientific instruments on board, including the mastcam which consists of two cameras and can take high-resolution images and videos in real colour. 

So far on the journey of the car-sized robot it has encountered an ancient streambed where liquid water used to flow, not long after it also discovered that billions of years ago, a nearby area known as Yellowknife Bay was part of a lake that could have supported microbial life.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
