Curiosity Mars Rover Roadtrips And Rock-Hunts To Celebrate 9th Anniversary – Forbes

Published

Most of the Martian attention these days is fixed on the NASA Perseverance life-seeking mission, but we shouldn’t forget that the agency’s Curiosity is still going strong as it also looks for signs of ancient habitability.

Percy hit the headlines late last week when it was discovered that its first sampling attempt did not go to plan. The new rover is supposed to cache a bunch of promising rocks and samples for a future sample-return mission, to bring Martian stuff back to Earth by 2031 if funding and tech development holds. (The thinking is it would be easier to search for ancient Martian microbes using high-tech equipment on Earth.)

But Perseverance’s mission is greatly informed by Curiosity, which stuck the landing in Gale Crater on Aug. 6, 2012. Within days of arriving, Curiosity found signs of an ancient streambed. Within a few months, it was slowly on the road to its ultimate destination — Aeolis Mons (Mount Sharp). Curiosity is still climbing that mountain in a bid to understand the history of water on Mars, and how habitable the planet might have been in the past.

On the 6th (Earth time), Curiosity was working on analyzing a couple of rocks and it also did a short drive of just 46 feet (14 meters), NASA’s Jet Propulsion Laboratory reported in an Aug. 6 update. Curiosity began to accidentally tear up its wheels early in the mission and JPL remains very protective of them, because without wheels that rover won’t go far.

“The terrain is so rocky that it’s hard to see too far beyond the rover’s current position. We don’t want to use too much autonomous driving in this rocky terrain and risk damaging the wheels,” JPL stated Aug. 6. Happily, the Perseverance rover’s wheels were reinforced in such a way that it should stand up to rocky terrain for many years, without the holes that Curiosity has been carefully managing by driving on smooth surfaces as much as possible.

Curiosity is moving along in its 10th year of observations in the wake of a new study that has an alternate view about the area it is exploring. A new Science Advances study suggests that volcano- and wind-blown deposits modified by acid rain — not water — was responsible for the weathering that the rover has observed in Gale Crater and its surroundings for the past decade.

For example, the study discusses the Yellowknife Bay formation near Curiosity’s landing site, which contains sandstones “interbedded” with mudstones. Such a formation is difficult to explain through lake depositions alone, the authors assert, and say that the rocks would require “several episodes of eolian-dominated [wind] activity”, perhaps through “airfall deposition of dust or likely volcanic ash.”

The authors’ work suggests that any lakes that Curiosity saw were smaller and more transient, meaning it would be harder for life to get a foothold. That said, none of the authors are on the long-running Curiosity team, and we will need to see if more studies confirm their findings.

The clays Curiosity keeps seeing on the slopes of Mount Sharp,, however, do suggest a lot of water-bearing activity in that region. Moreover, the rover has found multiple examples of organics — the building blocks of life — along with spikes of methane (a gas that can be indicative of life or non-life bearing processes; which is happening on Mars is not yet known.)

With Curiosity having been approved for multiple extended missions, it’s clear that the rover so far has been delivering on its mandate to produce valuable science about the evolution of the Martian climate and its possibilities for hosting life. So far, the rover has driven 16.17 miles (26 km) on Mars and it remains in good shape, despite the wheels. Curiosity should therefore keep rolling on Mars for at least several more years in search of more information about the planet’s history.

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.
