NASA’s Mars rover to begin ‘most challenging’ journey up crater rim
(NEW YORK) — Marking a new journey in NASA’s exploration of Mars, the Perseverance rover is set to begin a monthslong, steep and challenging ascent up a crater, the space agency announced Wednesday.
The Perseverance rover, nicknamed “Percy,” is the centerpiece of NASA’s Mars 2020 mission, working to collect data in preparation for future human exploration of the Red Planet.
The car-sized spacecraft has spent two and a half years exploring the Mars Jezero Crater floor and river delta and beginning the week of Aug. 19, will start the ascent up the western rim of the crater.
“Perseverance has completed four science campaigns, collected 22 rock cores, and traveled over 18 unpaved miles,” Art Thompson, Perseverance project manager at of NASA’s Jet Propulsion Laboratory in Southern California, said in a press release Wednesday.
“As we start the Crater Rim Campaign, our rover is in excellent condition, and the team is raring to see what’s on the roof of this place,” Thompson added.
In what will be the “most challenging” journey for the rover to date, Perseverance will rely on auto-navigation capabilities while encountering slopes of up to 23 degrees on the pre-planned path up the crater.
When Perseverance summits the crater, which scientists have dubbed “Aurora Park,” the rover will have gained approximately 1,000 feet in elevation.
Researchers are looking forward to the new frontier of data that awaits the rover on the crater rim, saying the mission expects “many more discoveries to come.”
Eleni Ravanis, a University of Hawaiì at Mānoa scientist on Perseverance’s Mastcam-Z instrument team and one of the Crater Rim Campaign science leads, said the findings will have “significant implications” in understanding the Red Planet.
“Our samples are already an incredibly scientifically compelling collection, but the crater rim promises to provide even more samples that will have significant implications for our understanding of Martian geologic history,” Ravanis said in the release.
(NEW YORK) — Recent images released from NASA have revealed new information on the origins of the asteroid system.
Nearly two years ago, the Double Asteroid Redirection Test spacecraft, or DART, collided with Dimorphos, a small asteroid that is the moon of a bigger space rock, Didymos, at about 14,000 miles per hour, testing a strategy to defend against a potential asteroid headed toward Earth.
In a slate of studies published this week, NASA researchers have suggested that the mission did far more than accomplish its initial goal.
The five papers, published in the journal Nature Communications, have provided information on the origins, physical characteristics and evolution of the asteroids and are helping scientists gain a greater understanding of binary asteroid systems like planet asteroid Didymos and moonlet Dimorphos.
“These findings give us new insights into the ways that asteroids can change over time,” Thomas Statler, lead scientist for Solar System Small Bodies at NASA Headquarters in Washington, said in a statement.
He went on, “This is important not just for understanding the near-Earth objects that are the focus of planetary defense, but also for our ability to read the history of our Solar System from these remnants of planet formation. This is just part of the wealth of new knowledge we’ve gained from DART.”
In one study, researchers from the Johns Hopkins Applied Physics Laboratory in Maryland studied the geology of the asteroids. They found Didymos was smoother at lower elevations, rockier at high elevations and had more craters while the moonlet Dimorphos had boulders of varying sizes.
The team concluded that Dimorphos likely spun off from Didymos in what is known as a “large mass shedding event,” which are natural processes that speed up the spinoff of smaller asteroids.
The team’s analysis suggested Didymos has a surface age between 40 and 130 times older than Dimorphos with the former estimated to be 12.5 million years old and the latter less than 300,000 years old, NASA said.
Because Dimorphos’ surface is younger, it likely had “low strength” which, in turn, contributed to why DART was so successful in disrupting its orbit.
In another paper, researchers compared the shapes and sizes of the boulders on the two asteroids and determined Dimorphos likely formed in stages with material from Didymos, providing further evidence that the former spun off from the latter.
A third study compared the boulders on Dimorphos to rubble pile asteroids — asteroids that are made up of pieces of debris — and found they shared similar characteristics, concluding all the asteroids likely formed similarly.
“The images and data that DART collected at the Didymos system provided a unique opportunity for a close-up geological look of a near-Earth asteroid binary system,” Dr. Oliver Barnouin, a planetary geophysicist from Johns Hopkins APL, said in a statement. “From these images alone, we were able to infer a great deal of information on geophysical properties of both Didymos and Dimorphos and expand our understanding on the formation of these two asteroids. We also better understand why DART was so effective in moving Dimorphos.”
(FORT WALTON BEACH, Fla.) — A circuit court judge denied a former Florida deputy pre-trial release in connection with the shooting death of United States Air Force Sr. Airman Roger Fortson who was killed in his own home.
Rod Smith, the attorney for ex-deputy Eddie Duran, 38, who made his first court appearance Tuesday via Zoom, asked the court for Duran’s release until his next court appearance on Thursday at 12:30 p.m.
“I think he should be released now. We’ll be back Thursday. And there’s no reason to think – we’ve had this thing hanging over us since May,” Smith said. “We believe that he’s no risk, no flight risk. He’s going to show up there. He’s going to show up anytime.”
The state argued that Duran should not be granted pre-trial release because of a new Florida statute that requires him to stay in custody without bond as he is charged with a first-degree felony. The Okaloosa County Circuit Court judge told Duran that he would stay in jail until his next hearing.
Duran’s arrest on Monday comes after the Florida state attorney filed one count of manslaughter with a firearm against him on Friday. The charge carries a maximum sentence of 30 years.
Fortson, 23, was in his home in Fort Walton Beach, Florida, on May 3 when Duran responded to the apartment for a call reporting a domestic disturbance, according to the Okaloosa County Sheriff’s Office. Fortson was alone in the apartment at the time, police said.
In body-worn camera footage released by the sheriff’s office, Fortson is seen holding a gun in his right hand with his arm extended downward and the muzzle pointing at the floor as he opens the door in response to the deputy, who can be heard announcing twice that he’s with the sheriff’s office. The footage, reviewed by ABC News, also shows Fortson had his left hand up, palm showing, gesturing towards the deputy when he opened the door.
Duran shot Fortson within seconds of the door opening, according to the footage. Fortson died of his injuries.
The deputy said he saw Fortson armed with a gun and claimed that Fortson took a step toward the deputy and had a look of aggression in his eyes, according to an interview Duran conducted with the sheriff’s office during their subsequent investigation.
The deputy was terminated in May, according to a sheriff’s department statement obtained by ABC News.
Fortson’s girlfriend, who asked not to be identified due to fears for her safety, spoke in May to Atlanta ABC affiliate WSB-TV, telling the station her and Fortson were having a conversation on the phone about weekend plans when the shooting occurred.
“We continue to wish Mr. Fortson’s family comfort and peace, as the former deputy’s criminal case proceeds,” the Okaloosa County Sheriff’s Office previously told ABC News in a statement. “We stand by our decision to terminate Mr. Duran as a result of the administrative internal affairs investigation that found his use of force was not objectively reasonable.”
A sweep of the home did not find another person in the apartment besides Fortson, police said. In the body camera video, a woman, presumed to be a building manager, explains to the officer that someone in the building notified her of the disturbance and that she called police.
Fortson’s family said in a statement to ABC News on Friday that the charges marked a “first step towards justice” in the case.
“Nothing can ever bring Roger back, and our fight is far from over, but we are hopeful that this arrest and these charges will result in real justice for the Fortson family,” the statement said. “Let this be a reminder to law enforcement officers everywhere that they swore a solemn oath to protect and defend, and their actions have consequences, especially when it results in the loss of life.”
The state attorney’s office said it’s very limited in what it can say because there is still an ongoing investigation.
(WASHINGTON) — Cecilia sat in front of her computer repeatedly refreshing the U.S. Citizenship and Immigration Services webpage on Monday, waiting for the application for the Biden administration’s “Keeping Families Together” program to show up on her screen.
Minutes later, she clicked it open and submitted the form in less than 20 minutes.
A little more than 24 hours later, she got an e-mail sharing the news that she had been waiting 20 years to hear.
“I see that I got approved, and I’m like, oh that was quick,” she told ABC News in an interview. “I was lost for words…a whole bunch of emotions were going on.”
Cecilia, who asked ABC News not to disclose her full name so she can freely disclose her immigration status, is one of the first immigrants to receive parole in place, a temporary relief from deportation under a new program that allows undocumented spouses and stepchildren of United States citizens to apply for permanent legal residence without having to leave the country.
Noncitizen spouses are already eligible for legal status under current laws but often have to apply from their home countries and face up to a 10-year ban from returning to the U.S.
On June 18, President Joe Biden announced an executive action launching the program, calling it a “commonsense fix” to keep families together.
“This action is a better way. It doesn’t tear families apart, while requiring every undocumented spouse to fulfill their obligations under the law,” Biden said.
It’s estimated that half a million noncitizen spouses and 50,000 children could benefit from the program, according to the Department of Homeland Security.
In order to qualify for the program, applicants must be in the country unlawfully and pass background checks. They also have to prove they’ve lived in the country for at least a decade and must be married to a U.S. citizen on or before June 17, 2024.
Some noncitizen stepchildren under the age of 21 are also eligible.
Cecilia’s family brought her to the U.S. from Mexico when she was a 4-year-old, she told ABC News.
After unsuccessfully applying for the Deferred Action for Childhood Arrivals (DACA) program, which continues to be paused pending a yearlong battle that could permanently end the program, she thought her dreams of finally being able to pursue a career as a chemist were over. For years, she said her parents worked to help her with paying out of state tuition because of her status.
In 2018, she met her future husband when he was studying biology at the same school.
“At the time I didn’t really tell him about my status, because I was like, what if he doesn’t like me because I’m not here legally,” she told ABC News.
However, she said her husband was overwhelmingly supportive of her despite her being undocumented. He has helped her get through school while raising their 3-year-old. He was working when she shared the news that her application was approved.
“He was like, ‘Are you not playing with me?'” she recalled. They went to celebrate as soon as he got home.
“We always try to celebrate little moments in our lives, even if they’re small, because we never know when one us might not be there and we try to be united as a family, she said.
Cecilia learned about the new policy from American Families United, a nonprofit organization that advocates for legal pathways to citizenship for foreign nationals married to U.S. citizens.
“Countless American families like Cecilia’s have endured years of uncertainty, holding onto the hope that one day they could live without fear,” said Ashley DeAzevedo, president of American Families United, in a statement. “We are encouraged to see the quick approval of Cecilia’s application—she is American in every way that counts. Now, she will have the opportunity to contribute even more to her family and this nation that she calls home.”
Cecilia believes that because she had already submitted biometrics and other information to USCIS as part of her DACA application, her case was expedited.
A USCIS official told ABC News that the agency may prioritize applicants who already have other pending applications and have submitted accurate biographic information.
Cecilia has already applied for her work permit and plans to apply for lawful permanent residence status as soon as she’s able to, finally putting the frustration of living in limbo as an undocumented immigrant in the past for good. Her dreams of owning a home, launching her career and raising her child with her husband seem within reach.
She’s urging other undocumented immigrants to remain hopeful.
“I feel like people should be more hopeful and that there are people advocating for them,” she said. “Everyone deserves an extra opportunity.”
