Vishnu Sridhar, a 27-year-old Indian-American lead system engineer with NASA’s Perseverance rover, has said that the most exciting work on the awe-inspiring Mars mission will happen in the coming weeks.

Sridhar, who is from Queens, New York, is a lead system engineer at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California for SuperCam on the Mars 2020 Perseverance rover, which is on a mission to search for signs of past life on the Red Planet.

He said some of the rover’s most exciting work will be done in the coming weeks.

“We’re going to be taking more images of Mars, we’re going to be shooting lasers with the SuperCam instrument, we’re going to be recording audio with our microphone, and eventually, soon in near future, we are going to deploy our helicopter, and do the first powered flight on Mars,” Sridhar told ABC7 channel.

SuperCam is a remote-sensing instrument that will use laser spectroscopy to analyse the chemical composition of rocks on the Martian surface.

It analyses terrain that the rover cannot reach. It is an instrument designed to scan rocks and minerals—from up to 20 feet away—to determine their chemical makeup. The Perseverance rover was launched on July 30 last year and successfully landed on Mars on February 18 this year.

The rover, the SuperCam, and its other devices together will help scientists search for clues of past life on Mars. Its predecessor Curiosity is still functioning eight years after landing on Mars.

The two-year Perseverance mission is NASA’s latest and most advanced mission to find evidence of past life on Mars.

Sridhar said it was important that the mission was happening despite the ongoing COVID-19 pandemic.

“NASA missions are clearly trying to explore and answer the basic question.

Perseverance is also trying to seek that, and eventually answer the question that was there life on Mars, was there life outside Earth, and it was definitely a tough period for us during COVID-19 and for everyone else around the globe,” he said.

“And that’s why I love the name of Perseverance because we persevered through the pandemic and there was a paradigm shift, we learned a lot about how to do engineering remotely.

And we went through all that we learned and now we are successful on Mars and it’s a great achievement for humankind,” he said.

Sridhar’s time at JPL over the past five years has been dedicated to Mars and is currently the instrument engineer for SuperCam on the Mars 2020 Rover.

“Summer 2019 was when instruments came in from France and Los Alamos and when we physically integrated SuperCam with the Perseverance rover.

That’s something I will cherish for the rest of my life, to have touched and worked on a piece of hardware that’s on its way to Mars,” he reminisced.

The US space agency on Monday released the first audio from Mars, a faint recording of a gust of wind captured by the Perseverance rover.

Perseverance will attempt to collect 30 rock and soil samples in sealed tubes to be sent back to Earth sometime in the 2030s for lab analysis.

The rover is only the fifth to set its wheels down on Mars.

The feat was first accomplished in 1997, and all of them have been American.

The US is aiming for an eventual human mission to the planet, though planning remains preliminary.

Sridhar attended Aviation High School in Queens and grew up in Rego Park.

He graduated in Aerospace Engineering from Georgia Tech and has always been fascinated by flight and space exploration.

“One of the key events that sparked my interest in space and exploration was watching National Geographic.

The Carl Sagan TV show Cosmos,” he said.

According to his NASA profile page, while in elementary school he wanted to become a National Geographic photographer and travel the world.

Indian-American woman scientist Swati Mohan had also played a key role in NASA Mars rover landing.

Mohan, who leads the guidance, navigation, and control operations of NASA’s Mars 2020 mission, was the first to confirm that the rover had successfully touched down on the Martian surface.

“Touchdown confirmed! Perseverance safely on the surface of Mars, ready to begin seeking signs of past life,” Mohan announced, prompting her colleagues at NASA to fist-bump and break into celebrations.

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.
