BEIJING — China launched its most ambitious Mars mission yet on July 23 in a bold attempt to join the US in successfully landing a spacecraft on the red planet.

Engines blazing orange, a Long March-5 carrier rocket took off under clear skies around 12:40 p.m. from Hainan Island, south of China’s mainland. Hundreds of space enthusiasts cried out excitedly on a beach across the bay from the launch site.

“This is a kind of hope, a kind of strength,” said Li Dapeng, co-founder of the China branch of the Mars Society, an international enthusiast group. He wore a Mars Society T shirt, and was there with his wife, 11-year-old son and 2,000 others on the beach to watch the launch.

Launch commander Zhang Xueyu announced to cheers in the control room that the rocket was flying normally about 45 minutes later. “The Mars rover has accurately entered the scheduled orbit,” he said in brief remarks shown live on state broadcaster CCTV.

China’s space agency said that the rocket carried the probe for 36 minutes before successfully placing it on the looping path that will take it beyond Earth’s orbit and eventually into Mars’ more distant orbit around the sun.

Liu Tongjie, spokesman for the mission, said in a press briefing that the launch was a “key step of China marching towards farther deep space.” He said that China’s aim wasn’t to compete with other countries, but to peacefully explore the universe.

It marked the second flight to Mars this week, after a United Arab Emirates orbiter blasted off on a rocket from Japan on Monday. And the US is aiming to launch Perseverance, its most sophisticated Mars rover ever, from Cape Canaveral, Florida, next week.

“It’s amazing that another nation has launched the case for Mars,” said Dr. Katarina Miljkovic, a planetary scientist at Curtin University in Australia, adding that the world was no longer in a space race. “It’s more like this marathon of space that we all want to be running.”

China’s tandem spacecraft – with both an orbiter and a rover – will take seven months to reach Mars, like the others. If all goes well, Tianwen-1, or “quest for heavenly truth,” will look for underground water, if it’s present, as well as evidence of possible ancient life.

This isn’t China’s first attempt at Mars. In 2011, a Chinese orbiter accompanying a Russian mission was lost when the spacecraft failed to get out of Earth’s orbit after launching from Kazakhstan, eventually burning up in the atmosphere.

This time, China is going at it alone. It also is fast-tracking, launching an orbiter and rover on the same mission instead of stringing them out.

China’s secretive space program has developed rapidly in recent decades. Yang Liwei became the first Chinese astronaut in 2003, and last year, Chang’e-4 became the first spacecraft from any country to land on the far side of the moon.

Conquering Mars would put China in an elite club.

“There is a whole lot of prestige riding on this,” said Dean Cheng, an expert on Chinese aerospace programs at the Heritage Foundation in Washington.

The launch was “gutsy,” said Dr. Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics. The next challenge is for the probe to be “still working when it gets to Mars and survives entry and landing.”

Landing on Mars is notoriously difficult. Only the US has successfully landed a spacecraft on Martian soil, doing it eight times since 1976. NASA’s InSight and Curiosity rovers still operate today. Six other spacecraft are exploring Mars from orbit: three American, two European and one from India.

Unlike the two other Mars missions launching this month, China has tightly controlled information about the program – even withholding any name for its rover. National security concerns led the US to curb co-operation between NASA and China’s space program.

In an article published earlier this month in Nature Astronomy, mission chief engineer Wan Weixing said Tianwen-1 would slip into orbit around Mars in February and look for a landing site on Utopia Planitia – a plain where NASA has detected possible evidence of underground ice. Wan died in May from cancer.

The landing would then be attempted in April or May, according to the article. If all goes well, the 240-kilogram (530-pound) golf cart-sized, solar-powered rover is expected to operate for about three months, and the orbiter for two years.

There is uncertainty even after the rover lands on Mars, said Liu Tongjie. “For instance, if there is a sand storm, it needs to modify its mode of work to prevent sands falling on solar panel, which will affect its ability to get energy,” he said.

Though small compared to America’s hulking, car-sized 1,025-kilogram (2,260-pound) Perseverance, it’s almost twice as big as the two rovers China has sent to the moon in 2013 and 2019. Perseverance is expected to operate for at least two years.

This Mars-launching season – which occurs every 26 months when Earth and Mars are at their closest – is especially busy.

The UAE spacecraft Amal, or Hope, which will orbit Mars but not land, is the Arab world’s first interplanetary mission. NASA’s Perseverance rover is up next.

“At no other time in our history have we seen anything like what is unfolding with these three unique missions to Mars. Each of them is a science and engineering marvel,” the Space Foundation’s chief executive officer Thomas Zelibor said in an online panel discussion earlier this week.

China’s road to Mars hit a few bumps: A Long March-5 rocket, nicknamed “Fat 5” because of its bulky shape, failed to launch earlier this year. The coronavirus pandemic forced scientists to work from home. In March, when instruments needed to be transported from Beijing to Shanghai, three team members drove 12 hours to deliver them.

While China is joining the US, Russia and Europe in creating a satellite-based global navigation system, experts say it isn’t trying to overtake the US lead in space exploration.

Instead, Cheng of the Heritage Foundation said China is in a “slow race” with Japan and India to establish itself as Asia’s space power.

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

Published

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.
