NASA launches spacecraft to deflect asteroid from collision with Earth

A spacecraft that must ultimately crash to succeed was launched late on Tuesday from California on a NASA mission to demonstrate the world’s first planetary defense system, designed to deflect an asteroid from a potential doomsday collision with Earth.

The DART spacecraft soared into the night sky at 10:21 p.m. Pacific time on Tuesday (1:21 a.m. Eastern/0621 GMT Wednesday) from Vandenberg US Space Force Base, about 150 miles northwest of Los Angeles, carried aboard a SpaceX-owned Falcon 9 rocket.

The launch was shown live on NASA TV.
The DART payload, about the size of a small car, was released from the booster minutes after launch to begin a 10-month journey into deep space, some 6.8 million miles (11 km) from Earth.
Once there DART will test its ability to alter an asteroid’s trajectory with sheer kinetic force, plowing into it at high speed to nudge the space boulder off course just enough to keep our planet out of harm’s way.
Cameras mounted on the impactor and on a briefcase-sized mini-spacecraft to be released from DART about 10 days beforehand will record the collision and beam images of it back to Earth.
The asteroid DART is aimed at poses no actual threat and is tiny compared with the cataclysmic Chicxulub asteroid that struck Earth some 66 million years ago, leading to extinction of the dinosaurs. But scientists say smaller asteroids are far more common and pose a greater theoretical danger in the near term.
DART’s target is an asteroid “moonlet” the size of a football stadium that orbits a chunk of rock five times larger in a binary asteroid system named Didymos, the Greek word for twin.
The team behind DART, short for Double Asteroid Redirection Test, chose the Didymos system because its relative proximity to Earth and dual-asteroid configuration make it ideal for observing the results of the impact.

Bumping asteroid moonlet

The plan is to fly the DART spacecraft directly into the moonlet, called Dimorphos, at 15,000 miles per hour (24,000 kph), bumping it hard enough to shift its orbital track around the larger asteroid.
Cameras on the impactor and on a briefcase-sized mini-spacecraft released from DART about 10 days beforehand will record the collision and beam images back to Earth. Ground-based telescopes will measure how much the moonlet’s orbit around Didymos changes.
The DART team expects to shorten Dimorphos’ orbital track by 10 minutes but would consider at least 73 seconds a success. A small nudge to an asteroid millions of miles away would be sufficient to safely reroute it.
DART is the latest of several NASA missions of recent years to explore and interact with asteroids, primordial rocky remnants from the solar system’s formation 4.6 billion years ago.
Last month, NASA launched a probe on a voyage to the Trojan asteroid clusters orbiting near Jupiter, while the grab-and-go spacecraft OSIRES-REx is on its way back to Earth with a sample collected last October from the asteroid Bennu.
The Dimorphos moonlet is one of the smallest astronomical objects to receive a permanent name and is one of 27,500 known near-Earth asteroids of all sizes tracked by NASA.
Although all none poses a foreseeable hazard to humankind, NASA estimates many more asteroids remain undetected in the near-Earth vicinity.
The DART spacecraft, cube-shaped with two rectangular solar arrays, is due to rendezvous with the Didymos-Dimorphos pair in late September 2022.
NASA put the entire cost of the DART project at $330 million, well below that of many of the space agency’s most ambitious science missions.

Asian art fair in Hong Kong aims to bounce back after COVID-19 years

The organizers of Art Basel Hong Kong, one of Asia’s leading contemporary art fairs, said on Tuesday they are bullish on art market prospects in the region, with China and Hong Kong now having lifted all COVID-19 lockdown restrictions.
The annual fair, which also has iterations in Basel, Paris, and Miami Beach, runs from March 23-25 in Hong Kong.

The number of galleries has increased to 177 this year from 130 in 2022, with 32 countries and territories across Asia, Europe, the Americas, and Africa participating.
“Despite the challenges of the pandemic, the Asian art market has also remained resilient, with Greater China accounting for 20 percent of worldwide sales by value and ranking second as the second largest regional art market in the latest edition of the Art Basel,” Art Basel CEO Noah Horowitz told reporters.
Hong Kong attracted 56 million visitors in pre-pandemic 2019 but shops now sit vacant and Chinese visitors, who once propelled the city’s art market, have yet to return in droves.
Leading international galleries at Art Basel this year include Gagosian, Hauser & Wirth, Lehmann Maupin, Victoria Miro, Pace, Perrotin, White Cube and David Zwirner.
In a mall near the glitzy halls of Hong Kong’s harborfront convention center where Art Basel, the show has installed a 10-meter-tall inflatable sculpture of Egyptian pharaoh Tutankhamun titled ‘Gravity’ by Los Angeles-based artist Awol Erizku.
Hong Kong’s government has welcomed the art fair as it strives to reinvigorate Hong Kong’s economy after a nearly three-year slump from factors including tough COVID-19 lockdowns, a closed border with China, and a security crackdown.
Hundreds of thousands of people have left the territory since June 2020, when a sweeping national security law was passed that has been used to curb freedoms and arrest scores of opposition democrats and shutter liberal media outlets.
Some Western governments have criticized the law as a tool of repression, but China asserts it brought stability after pro-democracy protests in 2019.
Art Basel said it had respected creative expression.
“We don’t have any censorship process in the show. We haven’t really changed the process of the show since 2013,” said Angelle Siyang-Le, the director Art Basel Hong Kong.

Actress Gwyneth Paltrow to stand trial for ski crash in upscale Utah resort

Gwyneth Paltrow is scheduled to stand trial on Tuesday in a lawsuit filed by a retired optometrist who said that the actress-turned-lifestyle influencer violently crashed into him in 2016 while skiing in Utah at one of the most upscale ski resorts in the United States.

Terry Sanderson, 76, said Paltrow was cruising down the slopes so recklessly that they collided, leaving him on the ground as she and her entourage continued their descent down Deer Valley Resort, a skiers-only mountain known for its groomed runs, après-ski champagne yurts and posh clientele.

For the latest headlines, follow our Google News channel online or via the app.
“Gwyneth Paltrow skied out of control,” Sanderson’s attorneys claim in the lawsuit, “knocking him down hard, knocking him out, and causing a brain injury, four broken ribs and other serious injuries. Paltrow got up, turned, and skied away, leaving Sanderson stunned, lying in the snow, seriously injured.”

In a case that has lasted years since the 2016 incident, Sanderson is suing Paltrow for $300,000 — claiming that the accident in Park City was a result of negligence, and left him with physical injuries and emotional distress.

At ski resorts, the skier who is downhill has the right of way, so a central question in the case is who was further down the beginner’s run when the collision transpired. Both Paltrow and Sanderson claim in court filings that they were further downhill when the other rammed into them.

Sanderson also accused Deer Valley and its employees of engaging in a “cover up” by not providing complete information on incident reports and not following resort safety policies.

After his initial lawsuit seeking $3.1 million was dropped, Sanderson amended the complaint and he is now seeking $300,000. Paltrow — the Oscar-winning actress known for her roles in “Shakespeare in Love” and Marvel’s “Iron Man” movies — filed a counterclaim in response, seeking attorney fees and $1 in damages.

Paltrow has countered that he was actually the culprit in the collision, is overstating his injuries, and trying to exploit her celebrity and wealth. In addition to her acting career, she is also the founder and CEO of the high-end wellness company, goop.
In court filings, her attorneys deny Sanderson’s claims and allege that he was the one who crashed into her — a collision in which she sustained a “full body blow.” Her counterclaim alleges that members of Paltrow’s group checked on Sanderson, who assured them he was fine. It casts doubt on his motive and claims of injury, noting that before the incident, he had 15 documented medical conditions.

“He demanded Ms. Paltrow pay him millions. If she did not pay, she would face negative publicity resulting from his allegations,” her attorneys wrote in a 2019 court filing.

The trial in Park City is slated to last longer than a week.

Rafa Nadal out of top 10 for first time since 2005

Rafa Nadal’s absence from Indian Wells saw the 22-times Grand Slam champion slip out of the top 10 for the first time since 2005 on Monday but the Spaniard will still be the “man to beat” at the French Open if he can get back to full fitness.
Nadal was forced to skip the Masters 1000 event in California, where he reached the final last year, as he continues his recovery from a hip issue that ended his Australian Open title defense in the second round in January.

For the latest headlines, follow our Google News channel online or via the app.
Unable to defend the 600 points from Indian Wells resulted in Nadal dropping four places to 13th in the rankings, ending his record 912-week stay inside the top 10, which began when current number one Carlos Alcaraz was not even two years old.
However, with Nadal preparing to return to action at the Monte Carlo Masters next month ahead of the French Open, which he has won 14 times in his career, his time outside the top 10 might be short.
World number four Casper Ruud, who lost to Nadal in the Roland Garros final last year, said he would not be shocked to see the 36-year-old lift the trophy once again.
“It wouldn’t surprise me because he’ll probably use these weeks and these months, as he’s preparing for exactly Roland Garros,” Ruud told Eurosport as part of the ‘Ruud Talk’ series.
“It doesn’t matter if he loses in Monte Carlo or Rome or Madrid. The only thing that’s probably on his mind these days is just to be fit, be healthy, and be ready for Roland Garros.”
Tennis lost two of its greats when Serena Williams and Roger Federer bowed out of the sport last year, but Nadal and rival Novak Djokovic are still soldiering on.
Djokovic, who turns 36 in May, has shown few signs of slowing down and drew level with Nadal on 22 Grand Slams by winning the Australian Open.
“For the whole tennis world it would be nice to see one last showdown at Roland Garros,” former US Open champion Dominic Thiem said, adding that Djokovic would be favorite to win the remaining Grand Slams this year.
“The only tournament is Roland Garros: if Rafa is fit there, it’s exactly the opposite. He’s the man to beat when he won the tournament 14 times, it’s crazy.”
