NASA’s Perseverance rover snagged its first Martian rock samples

The Perseverance rover has captured its first two slices of Mars.

NASA’s latest Mars rover drilled into a flat rock nicknamed Rochette on September 1 and filled a roughly finger-sized tube with stone. The sample is the first ever destined to be sent back to Earth for further study. On September 7, the rover snagged a second sample from the same rock. Both are now stored in airtight tubes inside the rover’s body.

Getting pairs of samples from every rock it drills is “a little bit of an insurance policy,” says deputy project scientist Katie Stack Morgan of NASA’s Jet Propulsion Lab in Pasadena, Calif. It means the rover can drop identical stores of samples in two different places, boosting chances that a future mission will be able to pick up at least one set.

The successful drilling is a comeback story for Perseverance. The rover’s first attempt to take a bit of Mars ended with the sample crumbling to dust, leaving an empty tube (SN: 8/19/21). Scientists think that rock was too soft to hold up to the drill.
Nevertheless, the rover persevered.

“Even though some of its rocks are not, Mars is hard,” said Lori Glaze, director of NASA’s planetary science division, in a September 10 news briefing.

Rochette is a hard rock that appears to have been less severely eroded by millennia of Martian weather (SN: 7/14/20). (Fun fact: All the rocks Perseverance drills into will get names related to national parks; the region on Mars the rover is now exploring is called Mercantour, so the name Rochette — or “Little Rock” — comes from a village in France near Mercantour National Park.)

Rover measurements of the rock’s texture and chemistry suggests that it’s made of basalt and may have been part of an ancient lava flow. That’s useful because volcanic rocks preserve their ages well, Stack Morgan says. When scientists on Earth get their hands on the sample, they’ll be able to use the concentrations of certain elements and isotopes to figure out exactly how old the rock is — something that’s never been done for a pristine Martian rock.

Rochette also contains salt minerals that probably formed when the rock interacted with water over long time periods. That could suggest groundwater moving through the Martian subsurface, maybe creating habitable environments within the rocks, Stack Morgan says.

“It really feels like this rich treasure trove of information for when we get this sample back,” Stack Morgan says.

Once a future mission brings the rocks back to Earth, scientists can search inside those salts for tiny fluid bubbles that might be trapped there. “That would give us a glimpse of Jezero crater at the time when it was wet and was able to sustain ancient Martian life,” said planetary scientist Yulia Goreva of JPL at the news briefing.

Scientists will have to be patient, though — the earliest any samples will make it back to Earth is 2031. But it’s still a historic milestone, says planetary scientist Meenakshi Wadhwa of Arizona State University in Tempe.

“These represent the beginning of Mars sample return,” said Wadhwa said at the news briefing. “I’ve dreamed of having samples back from Mars to analyze in my lab since I was a graduate student. We’ve talked about Mars sample return for decades. Now it’s starting to actually feel real.”

Astronomers may have seen a star gulp down a black hole and explode

For the first time, astronomers have captured solid evidence of a rare double cosmic cannibalism — a star swallowing a compact object such as a black hole or neutron star. In turn, that object gobbled the star’s core, causing it to explode and leave behind only a black hole.

The first hints of the gruesome event, described in the Sept. 3 Science, came from the Very Large Array (VLA), a radio telescope consisting of 27 enormous dishes in the New Mexican desert near Socorro. During the observatory’s scans of the night sky in 2017, a burst of radio energy as bright as the brightest exploding star — or supernova — as seen from Earth appeared in a dwarf star–forming galaxy approximately 500 million light-years away.

“We thought, ‘Whoa, this is interesting,’” says Dillon Dong, an astronomer at Caltech.

He and his colleagues made follow-up observations of the galaxy using the VLA and one of the telescopes at the W.M. Keck Observatory in Hawaii, which sees in the same optical light as our eyes. The Keck telescope caught a luminous outflow of material spewing in all directions at 3.2 million kilometers per hour from a central location, suggesting that an energetic explosion had occurred there in the past.
The team then found an extremely bright X-ray source in archival data from the Monitor of All Sky X-ray Image (MAXI) telescope, a Japanese instrument that sits on the International Space Station. This X-ray burst was in the same place as the radio one but had been observed back in 2014.

Piecing the data together, Dong and his colleagues think this is what happened: Long ago, a binary pair of stars were born orbiting each other; one died in a spectacular supernova and became either a neutron star or a black hole. As gravity brought the two objects closer together, the dead star actually entered the outer layers of its larger stellar sibling.

The compact object spiraled inside the still-living star for hundreds of years, eventually making its way down to and then eating its partner’s core. During this time, the larger star shed huge amounts of gas and dust, forming a shell of material around the duo.

In the living star’s center, gravitational forces and complex magnetic interactions from the dead star’s munching launched enormous jets of energy — picked up as an X-ray flash in 2014 — as well as causing the larger star to explode. Debris from the detonation smashed with colossal speed into the surrounding shell of material, generating the optical and radio light.

While theorists have previously envisioned such a scenario, dubbed a merger-triggered core collapse supernova, this appears to represent the first direct observation of this phenomenon, Dong says.

“They’ve done some pretty good detective work using these observations,” says Adam Burrows, an astrophysicist at Princeton University who was not involved in the new study. He says the findings should help constrain the timing of a process called common envelope evolution, in which one star becomes immersed inside another. Such stages in stars’ lives are relatively short-lived in cosmic time and difficult to both observe and simulate. Most of the time, the engulfing partner dies before its core is consumed, leading to two compact objects like white dwarfs, neutron stars or black holes orbiting one another.

The final stages of these systems are exactly what observatories like the Advanced Laser Interferometer Gravitational-Wave Observatory, or LIGO, detect when capturing spacetime’s ripples, Dong says (SN: 8/4/21). Now that astronomers know to look for these multiple lines of evidence, he expects them to find more examples of this strange phenomenon.

'Fire Nagy' chants take over Chicago after Bears' latest loss, including at Matt Nagy's son's football game

The "Fire Nagy" chants can be heard all over Chicago, from Soldier Field all the way to Matt Nagy's son's football games.

The Bears have now lost five straight games, and fans are frustrated, to say the least. They have aimed their anger at the 43-year-old head coach, who has found himself in the middle of the majority of Bears-related drama this season.
After Sunday's 16-13 loss to the Ravens, the Soldier Field crowd broke out into "Fire Nagy" chants. Then, on Monday night at the Bulls vs. Pacers game at the United Center, "Fire Nagy" chants could be heard. Then, on Tuesday, video surfaced showing that "Fire Nagy" chants took over his own son's football game on Saturday night.
Nagy's son plays football for Lake Forest High School in a Chicago suburb. Lake Forest played Cary-Grove High School on Saturday, and Cary-Grove captured a blowout victory, which prompted the Cary-Grove student section to start yelling "Fire Nagy."
Cary-Grove principal Neil Lesinski posted an apology on Twitter on Tuesday morning. His full statement:
It doesn't seem like the "Fire Nagy" chants will be going anywhere if the Bears continue to lose. They have a chance to get their fourth win of the season on Thanksgiving when they play the 0-9-1 Lions.

On Tuesday, there was a rumor circulating that Nagy's last game as coach would be against the Lions on Thursday. Nagy addressed these rumors with the media on Tuesday, claiming that they are "not accurate."

UEFA Champions League draw: Date, teams qualified, seeds, rules for Round of 16

The complete field of 16 teams that will advance to the 2021-22 UEFA Champions League knockout rounds has not yet been finalized, but we already have several clubs that have booked their spots.

European giants Liverpool, Ajax, Bayern Munich and Juventus were the first four teams to clinch on Matchday 4 of the group stage, while Manchester United and Chelsea joined them on Matchday 5.
Only the top two teams in each group advance, and there's incentive to win the group when it comes to the Round of 16 draw on Monday, Dec. 13. The first-place team from each group will be seeded, and their Round of 16 opponent will be drawn from a pot of the second-place finishers.

When is the Champions League Round of 16 draw?
The Round of 16 draw will be held on Dec. 13 at 6 a.m. ET from the UEFA headquarters in Switzerland. It will be streamed by UEFA.com.

The eight group winners will be seeded for purposes of the draw. They will make up one pot, while the other pot will contain the runners-up from each group.

The two key details to remember for this Round of 16 draw:

Teams from the same country cannot be drawn against one another (see table below);
The group winners (i.e. seeded teams) will host the second leg of each Round of 16 series. This is perceived to be an advantage because, if an extra-time session or penalty-kick shootout is needed, it would happen on home soil.
Knockout round qualifiers by country
Nation Total Clubs Clubs
England 3 Chelsea, Liverpool, Manchester United
Germany 1 Bayern Munich
Italy 1 Juventus
Netherlands 1 Ajax Amsterdam
The two legs of the Round of 16 will be spread over eight days between February and March. The second leg of each series will take place three weeks after the first leg.

The eight teams left standing will participate in a quarterfinal draw on March 18, 2022, which will determine the rest of the Champions League bracket through the final in Saint Petersburg on May 28. There are no seedings involved in this draw, and unlike the Round of 16, teams from the same country can be drawn against one another.

UEFA Champions League 2021-2022: Tournament format
The 2021-2022 edition of the UEFA Champions League features a familiar format — and one massive new twist.

As usual, the tournament started out with a group stage (eight groups of four teams each), and only the top two finishers in each group advance to the Round of 16 that kicks off in February 2022. Two-leg, aggregate-goal knockout rounds are played the rest of the way through to the single game final that will be held in Russia on May 28, 2022.

Group Stage: Sept. 14-15, Sept. 28-29, Oct. 19-20, Nov. 2-3, Nov. 23-24, Dec. 7-8
Round of 16: Feb. 15-16, March 8-9 / Feb. 22-23, March 15-16
Quarterfinals: April 5-6, April 12-13
Semifinals: April 26-27, May 3-4
Final: May 28, 2022 (St. Petersburg, Russia)
No away goals tiebreaker in Champions League
Here's that twist: For the first time since 1965, there will be no away goals tiebreaker used in the knockout rounds of UEFA competitions, including the Champions League, after it was abolished in June 2021.

Series that are tied on aggregate goals after the conclusion of the second leg will go straight to extra time and, if necessary, a penalty-kick shootout.

Steelers vs. Chargers final score, results: Austin Ekeler, Mike Williams power Chargers to late win over Steelers

The Chargers got outscored 27-14 in the fourth quarter on Sunday as Pittsburgh mounted a late comeback, but ultimately it wasn't enough for the Steelers, as Los Angeles won 41-37 after Justin Herbert hit Mike Williams for a 53-yard touchdown with 2:09 left to ice the game.

Herbert, along with running back Austin Ekeler out of the backfield, both did a bit of everything on offense. Herbert threw for 382 yards and three touchdowns while running for another 90. Ekeler, meanwhile, tallied four touchdowns — two rushing and two receiving — as he totaled 115 total yards.
The Chargers were 7-of-12 on third down, averaged 7.7 yards per play and amassed 533 yards of total offense. But it was two key plays late in the fourth quarter — a blocked punt and an interception by Justin Herbert — that allowed the Steelers to make a late comeback and even take the late lead for a short time.

Pittsburgh's offense flowed through Ben Roethlisberger, who turned in a three touchdown game as the ground game was sporadic at best, with Pittsburgh averaging just 3.1 yards per carry. Star rookie running back Najee Harris also missed much of the fourth quarter after being evaluated for a concussion. He was ultimately cleared to return on what wound up being Pittsburgh's final drive.

The win for Los Angeles improves its record to 6-4 and snaps a two-game home losing streak. They're now tied with Kansas City atop the AFC West with a game at Denver looming. Pittsburgh's loss drops it to 5-4-1, the Steelers' first loss since Oct. 3. They travel to Cincinnati next week to take on their fellow AFC North foes the Bengals.

Terence Crawford vs. Shawn Porter results: Crawford retains WBO welterweight title with 10th-round stoppage

LAS VEGAS — All the questions about Terence Crawford have been answered.

For years, the only knock on him was that he lacked a signature victory. He finally picked up one — and in exceptional fashion — when he became the first fighter to stop Shawn Porter, recording a 10th-round TKO to retain his WBO welterweight championship in front of 11,568 fans at Michelob ULTRA Arena.
Now, the world will be clamoring for a unification bout with IBF and WBC champion Errol Spence Jr.

As it always has been against Porter, winning didn't come easy.

At the time of the stoppage, Crawford was up on all three scorecards: 86-85, 86-85 and 87-84. Porter routinely barreled inside and kept Crawford off balance with aggression and pressure. But Crawford began to time Porter's advances and then picked him off with counters that eventually wore down the former two-time champion.

In the 10th round, Crawford opened with a thudding left hand that deposited Porter on his backside. A frustrated Porter made it to his feet but was met with a scintillating combination that dropped Porter to his knees. Porter pounded on the canvas out of frustration and made it back to his feet again. Unfortunately, his father and trainer, Kenny Porter, decided that his son had had enough and threw in the towel.

Crawford improved to 38-0 with 29 knockouts. Porter became his ninth consecutive knockout victim. As for Porter, his career is at a crossroads of sorts as he falls to 31-4-1 and goes to the back of the line when it comes to title opportunities.

Here's how it all went down in Las Vegas.

LeBron James: How did the Lakers star look in his return from injury in Boston?

The King is back. 

LeBron James returned from an almost three-week absence for the Los Angeles Lakers against the Boston Celtics on Friday night. James had been out of the Lakers lineup since November 2, missing the team's past seven games with an abdominal strain.

He was listed as a game-time decision with the team announcing he would play just before tip-off. 

Prior to his injury, James was averaging 24.8 points - his lowest scoring average since his rookie season - while also averaging his least amount of rebounds (5.5) also since his rookie campaign and his least amount of assists (7.0) since 2015-16. Most concerning was his shooting percentage (46.7 percent) which was also his lowest since 2003-04.

James played 32 minutes against Boston, and looked like his old self for large parts of the contest, hitting fadeaways, and taking it strong to the basket and absorbing contact. 

He finished with 23 points (10-for-16 from the field), six rebounds, two assists and two steals before exiting the game for good with 4:26 left in the final quarter. 

He played 32 minutes and recorded a team-best plus-minus of -4, among Lakers players to have logged more than 20 minutes.

"Felt okay," James said postgame. "Felt like a rookie again being away from the game."

With the 130-108 loss, the Lakers have dropped to 8-9 for the season and 4-3 in games when James suits up.

ESPN's Stephen A. Smith goes off on Nets after loss to Warriors, says Kyrie Irving 'betrayed' Kevin Durant

Stephen A. Smith was in attendance for Tuesday night's game between the Nets and Warriors. He didn't like what he saw from Brooklyn — and that's putting it mildly.

The ESPN analyst unloaded on the Nets during Wednesday's edition of "First Take" after watching the Warriors hand them a 117-99 loss at the Barclays Center. Golden State led by 22 points at the end of the third quarter, prompting Brooklyn coach Steve Nash to wave the white flag and pull Kevin Durant and James Harden out of the game. Warriors star Stephen Curry continued what has been an electric start, scoring a game-high 37 points on 12-of-19 shooting and earning MVP chants in the Nets' home arena.
Smith declared that Durant is "all alone" in Brooklyn and "made the wrong decision" by joining the franchise in 2019. He also unloaded on Harden for his poor play, ripped Kyrie Irving for his "betrayal" of Durant and called out Nets fans for their lack of spirit.

It was… a lot. His full comments:
The Nets are 10-5 overall, putting them behind only the Wizards (10-3) and Bulls (10-4) in the Eastern Conference standings. They have won eight of their last 10 games, and they have not gotten a single minute from Irving, who will continue to stay away from the team until he is compliant with local health and safety protocols. Smith paints an ugly picture, but things could be much worse.

Still, even Nash admits that the Nets don't belong in the top tier of NBA teams.

"I just don't think we're in that category yet," Nash told reporters Tuesday. "We got a lot of work to do."

It feels safe to say that Smith agrees with Nash's assessment.

Did Penguins' Sidney Crosby get away with a dirty play against the Capitals?

Sidney Crosby has played in just two of the Penguins' first 14 games this season. And even if he isn't lighting up the stat sheet, he certainly made his presence known on Sunday.

In the Penguins' 6-1 loss to the Capitals, Crosby struggled mightily. He recorded one shot on goal in just under 17 minutes of ice time, and let his frustration boil over in the third period.
After taking his lone shot on goal less than three minutes into the third period with Washington's Martin Fehervary playing defense, the two skated behind the net where Crosby threw the young defenseman face-first into the boards.
Crosby wasn't penalized on that play but did get sent to the box for cross-checking Evgeny Kuznetzov around seven minutes later. Tom Wilson scored on the ensuing power play to make it 6-1.
After the game, the 22-year-old Fehervary didn't seem to pay much mind to Crosby's actions and didn't really have much to say on the matter.

"Yeah, I don't know. I don't even know what should I talk about it," he told reporters. "I don't care. We'll see next game."
Crosby has zero points, five shot attempts and has a plus/minus of -4 to kick start his 2021-22 campaign. The star center — who has already been named to Canada's Olympic squad — missed the first seven games of the season while recovering from offseason surgery on his left wrist. He returned Oct. 30 vs. the Devils before having to enter COVID-19 protocols on Nov. 3. Sunday's game was his first time slotting in.

The Penguins and Capitals have had some notorious and infamous battles in recent years and will next face off on Dec. 10 in Washington.

How long is LeBron James out? Injury timeline, return date, latest updates on Lakers star

The Lakers will continue to lean on Anthony Davis and Russell Westbrook early in the 2021-22 season as they move forward without the services of their best player.

Los Angeles star LeBron James has missed the last two weeks of action with an abdominal strain. The four-time NBA MVP was sidelined for two of the Lakers' first eight games of the season before suffering the injury against the Rockets on Nov. 2.
What's next for James? Here's everything we know about his injury and the latest news on when he may return to the court.
What is LeBron James' injury?
The Lakers have listed James as out on recent injury reports with a rectus abdominis strain. That muscle group is "slung between the ribs and the pubic bone at the front of the pelvis," per BetterHealth.com, and its primary function is to "move the body between the ribcage and the pelvis."

An abdominal strain can cause sharp pains and result in difficulty stretching the muscle.
How long will LeBron James be out?
After the Lakers' game, against the Bucks, the first of five on the road, James said 'I hope I hope' when asked about suiting up in the team's next game against the Celtics.

However, ESPN's Dave McMenamin reports that it's a '50-50' chance that James could play on Friday at the TD Garden.

James was initially expected to miss two weeks, according to The Athletic's Shams Charania, who reported on Nov. 4 that the Lakers are taking a cautious approach with his injury.

"If this were the playoffs, could James push to play? Possibly," Charania said. "But James suffered the injury in Tuesday's win over the Rockets, and the Lakers want to be careful and manage the injury during the marathon of this NBA season."
However, Tim DiFrancesco, the Lakers' former head strength and conditioning coach, told The Athletic's Bill Oram that even a minor strain can take several weeks to heal.

"Especially the way he plays, it's tough for me to see him getting back under four weeks," DiFrancesco said. "Then again, he's a different dude, so I wouldn't put anything past him. … These are such delicate injuries that can respond to rest with pain relief quickly, but they are highly susceptible to re-injury if returned too quickly."
