Why go back to the Moon? – Phys.org

The United States is returning to the Moon 60 years after JFK’s famous speech.

On September 12, 1962, then US president John F Kennedy informed the public of his plan to put a man on the Moon by the end of the decade.

It was the height of the Cold War and America needed a big victory to demonstrate its space superiority after the Soviet Union had launched the first satellite and put the first man in orbit.

“We choose to go to the Moon,” Kennedy told 40,000 people at Rice University, “because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.”

Sixty years on, the United States is about to launch the first mission of its return program to the Moon, Artemis. But why repeat what has already been done?

Criticism has risen in recent years, for example from Apollo 11 astronaut Michael Collins, and the Mars Society founder Robert Zubrin, who have long advocated for America to go directly to Mars.

But NASA argues re-conquering the Moon is a must before a trip to the Red Planet. Here’s why.

Long space missions

NASA wants to develop a sustainable human presence on the Moon, with missions lasting several weeks –- compared to just a few days for Apollo.

The goal: to better understand how to prepare for a multi-year round trip to Mars.

In , radiation is much more intense and poses a real threat to health.

Low Earth Orbit, where the International Space Station (ISS) operates, is partly shielded from radiation by the Earth’s magnetic field, which isn’t the case on the Moon.

“We choose to go to the Moon,” Kennedy told 40,000 people at Rice University, “because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win”

From the first Artemis mission, many experiments are planned to study the impact of this radiation on living organisms, and to assess the effectiveness of an anti-radiation vest.

What’s more, while the ISS can often be resupplied, trips to the Moon—a thousand times further—are much more complex.

To avoid having to take everything with them, and to save costs, NASA wants to learn how to use the resources present on the surface.

In particular, water in the form of ice, which has been confirmed to exist on the , could be transformed into by cracking it into its separate hydrogen and .

Testing new gear

NASA also wants to pilot on the Moon the technologies that will continue to evolve on Mars. First, new spacesuits for spacewalks.

Their design was entrusted to the company Axiom Space for the first which will land on the Moon, in 2025 at the earliest.

Other needs: vehicles —both pressurized and unpressurized—so that the astronauts can move around, as well as habitats.

Finally, for sustainable access to an energy source, NASA is working on the development of portable nuclear fission systems.

Solving any problems that arise will be much easier on the Moon, only a few days away, than on Mars, which can only be reached in at least several months.

ASA also wants to test on the Moon the technologies that will continue to evolve on Mars.

Establishing a waypoint

A major pillar of the Artemis program is the construction of a space station in orbit around the Moon, called Gateway, which will serve as a relay before the trip to Mars.

All the necessary equipment can be sent there in “multiple launches,” before finally being joined by the crew to set off on the long voyage, Sean Fuller, responsible for the Gateway program, told AFP.

“Kind of like you’re stopping at your gas station to make sure you get all the stuff, and then you’re off on your way.”

Maintaining leadership over China

Apart from Mars, another reason put forward by the Americans for settling on the Moon is to do so before the Chinese, who plan to send taikonauts by the year 2030.

China is the United States’ main competition today as the once proud Russian program has withered.

“We don’t want China suddenly getting there and saying, “This is our exclusive territory,'” NASA boss Bill Nelson said in a recent interview.

For the sake of science

While the Apollo missions brought back to Earth nearly 400 kilograms of lunar rock, new samples will make it possible to further deepen our knowledge of this celestial object and its formation.

“The samples that we collected during the Apollo missions changed the way we view our solar system,” astronaut Jessica Meir told AFP. “I think we can expect that from the Artemis program as well.”

She expects further scientific and technological breakthroughs too, just like during the Apollo era.

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.
