Scientists in the United States and Canada are making final preparations for the arrival of a space capsule bearing precious cargo: fragments of rock and dust snatched from the surface of an asteroid that could shed light on the formation of Earth as a life-supporting planet.

The unmanned capsule is part of OSIRIS-REx, a NASA mission that launched in 2016 and collected a sample from the asteroid Bennu four years later. Its return journey is set to reach a dramatic conclusion on Sept. 24 when it enters Earth’s atmosphere high above western North America.

If all goes well, the cone-shaped craft, which is roughly the diameter of a car tire, will automatically deploy a parachute and touch down in the Utah desert at a military facility about 140 kilometres southwest of Salt Lake City. From there, the capsule will be whisked by helicopter to a temporary clean room and then to the Johnson Space Center in Houston.

“We’re very excited to be in the final phase of this long journey,” said Rich Burns, the mission’s project manager, at a news briefing at the Utah Test and Training Range on Wednesday.

The briefing followed a successful dress rehearsal of the retrieval process, using a mock capsule released from an altitude of about 2,130 metres.

Mission scientists estimate the OSIRIS-REx spacecraft was able to collect about 250 grams of material when it approached and briefly made contact with Bennu on Oct. 20, 2020.

The Canadian Space Agency is a participant in the mission and provided a laser altimeter that was used as part of the effort to map the 525-metre-wide asteroid and identify a favourable spot for the touch-and-go manoeuvre to capture a sample. In return, Canada is slated to receive a 4-per-cent share of the sample once it has been safely retrieved.

The mission marks the first attempt by the U.S. space agency to collect material from an asteroid, one of the solar system’s building blocks. It will also provide Canada with its first sample from any celestial body.

“The great thing about a sample-return mission is that it’s a gift that keeps on giving,” Timothy Haltigin, senior mission scientist for planetary exploration at the Canadian Space Agency, told The Globe and Mail.

“It’s not just the science that we’re going to do on the samples in the next few months,” he said. “It’s being able to make those samples available to generations of Canadian researchers,” he said.

Images from OSIRIS-REx show Bennu to be a boulder-strewn heap of rubble barely held together by gravity, like a “droplet of rock,” according to Dante Lauretta, a planetary scientist at the University of Arizona and the mission’s principal investigator.

The carbon-rich asteroid is thought to be a repository of material that is representative of what Earth and its neighbouring planets were built from when the solar system formed more than 4.5 billion years ago.

A key goal for the mission is to preserve any volatile substances such as water and organic molecules that the Bennu sample may contain. These are typically lost when asteroid fragments fall to Earth as meteorites. A pristine sample from Bennu would potentially offer scientists their best window yet on the contents of the early solar system and their role in the emergence of life on Earth.

“We’re looking for clues as to why Earth is a habitable world – this rare jewel in outer space that has oceans, that has a protective atmosphere,“ Dr. Lauretta said during Wednesday’s briefing. “And of course, the biggest question, the one that drives my scientific investigations, is the origin of 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.
