End of fun. The US is launching a nuclear-powered drone into space – Spark Chronicles

Published

NASA is thrilled with the enormous possibilities of a drone as small as it is Ingenuity, the first such device that has been exploring Mars for a year and helps the large Perseverance rover in its mission to search for traces of life. The Americans, however, did not rest on their laurels. American Space Agency is getting ready to launch its first drone into the brand new but equally fascinating world of Titan, the moon of Saturn. Engineers have been testing a bit larger for some time a drone called Dragonfly.

Videos of experiments conducted on California desert. We can see the drone skeleton itself there. At first glance, it looks like a normal device, but nothing could be further from the truth. The vehicle is the most advanced of its kind in the world today. It was created to fly in the extraterrestrial atmosphere of a celestial body that is alien to us.

Dragonfly will have to survive extreme conditions of Titan. On a daily basis, the temperature is minus 179 degrees Celsius, the atmospheric pressure at the surface is about 1.5 times greater than the earth’s air pressure at sea level, and the density of the atmosphere is about 4.5 times greater than that of the Earth’s air at sea level.

The aircraft will travel in full standalone mode. This is related to Titan’s distance from Earth. The data transfer time varies from 1 to 1.5 hours one way, which excludes control from Earth. – Titan is a space laboratory. A kitchen where the ingredients of the primal soup of life are brewed. That’s why we want to go there. More specifically, flying over it, thanks to the drone and the possibilities of augmented reality, said Dr. Elizabeth “Zibi” Turtle of Johns Hopkins University.

Scientists test the drone over Imperial Sand Dunes in California. Ultimately, the drone will be equipped with two cameras. One will be installed at the front and will be used to observe the space in front of the vehicle, while the other will be facing downwards. In addition to them, there will be a drill on board for retrieving and analyzing soil samples and a seismometer. The latter will collect valuable information about tectonic activity and help determine the thickness of the ice covering the moon.

Interestingly, Dragonfly will not be equipped with solar panels or batteries. Engineers from NASA decided to use a nuclear propulsionor actually a radioisotope thermoelectric generator. The launch is to take place in 2027, and in 2034 the drone will land on the surface of the facility. The mission will take place as part of the New Frontiers program, which aims to study alien worlds in the solar system.

When the mission is carried out, the entire drone fleet is to work on Mars, and the first human colonies may even be established there. Titanium is one of the most interesting objects known to us. The surface temperatures are very low, there are natural reservoirs of liquid hydrocarbons, and the atmosphere is dominated by nitrogen, which is similar to Earth. Astrobiologists believe that there are ideal conditions for the emergence and flourishing of various forms of life. Recently, an unusual molecule that was involved in the creation of human DNA was discovered there. Saturn’s moon in its present form resembles the Earth from billions of years ago.

According to the plan, the mission will be carried out in an area known as Shangri-La. It is located on the moon’s equator and abounds in sand dunes. They bring to mind views from African Namibia. The Selk crater will also be thoroughly explored. There are signs of water that once existed there, as well as complex organic molecules based on carbon.

Scientists plan that the scientific mission is to last 2.5 years. During its duration, the drone will travel about 175 kilometers of sandy areas and fly over methane and ethane tanks. The device will also examine the condition of the atmosphere. Scientists plan to take thousands of photos of the entire globe, and then use them to look for traces of life and interesting formations that can tell us the story of the evolution of this moon.

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.
