Heat’s Bradley on COVID-19 diagnosis: ‘I was really nervous’

Miami guard Avery Bradley went nearly two weeks without seeing his wife and children after testing positive for COVID-19, a brutally hard part of his ordeal with the illness. The sacrifice was worthwhile, though: None of them got the virus. Bradley confirmed Tuesday that he tested positive for the coronavirus last month. For anyone, that diagnosis can be daunting. For Bradley, that was especially so, given that he opted to not join his then-team, the Los Angeles Lakers, in the NBA’s restart bubble at Walt Disney World last season out of concerns about COVID-19 and the possibility of exposing his young son — who has chronic respiratory issues — to the disease. “I was really nervous,” Bradley said. “It’s just a blessing that no one in my household got COVID. It made me feel a lot more at ease. It was just frustrating knowing that the virus is still around. It’s been tough. It’s been tough for me and my family, but we’re getting through it. I’m happy my kids didn’t have it, my wife didn’t have it, that made me feel a lot better. “But it was tough not being around my family for 11 days, I think it was, not being able to see them, hug my kids, hug my wife. And I’m happy that it’s all over.” Bradley catching the virus was part of a challenging time for the Heat. They had only eight players available for two games at Philadelphia on Jan. 12 and 14, both of them losses, while eight others — Bradley among them — were out for virus-related reasons and Meyers Leonard was out with what became a season-ending shoulder injury. “No one is going to feel sorry for us,” Heat coach Erik Spoelstra said. Bradley has appeared in only 10 games for Miami this season; Tuesday’s game against New York is the 14th he is to miss, and that number will keep rising over the next few weeks. Bradley could be out until the end of the first-half schedule in early March with a strained calf muscle, though he’s hoping to return before the midseason break. He missed eight games because of COVID-19, then returned, bruised his knee in his comeback, sat out the next two contests, played two more games and then hurt the calf. “It’s really frustrating,” Bradley said. “It’s unfortunate, catching COVID, having the knee contusion and now this. It’s very frustrating. All I can do is continue to stay professional and make sure I’m doing everything I can do to get back as soon as possible, make sure I’m able to contribute and help our team in every way I can.” Bradley is averaging 8.5 points this season. The Heat start a seven-game road trip in Houston on Thursday; Bradley isn’t expected to travel because of his injury. ___ More AP NBA: https://apnews.com/hub/NBA and https://twitter.com/AP_Sports Tim Reynolds, The Associated Press

Spacewalking astronauts prep station for new solar wings – CP24 Toronto's Breaking News

Published

 on


CAPE CANAVERAL, Fla. — Spacewalking astronauts ventured out Sunday to install support frames for new, high-efficiency solar panels arriving at the International Space Station later this year.

NASA’s Kate Rubins and Victor Glover put the mounting brackets and struts together, then bolted them into place next to the station’s oldest and most degraded solar wings.

They had to lug out the hundreds of pounds of mounting brackets and struts in 8-foot (2.5-meter) duffle-style bags. The equipment was so big and awkward that it had to be taken apart like furniture, just to get through the hatch.

Some of the attachment locations required extra turns of the power drill and still weren’t snug enough, as indicated by black lines. The astronauts had to use a ratchet wrench to deal with the more stubborn bolts, which slowed them down. At one point, they were almost an hour behind.

“Whoever painted this black line painted outside the lines a little bit,” Glover said at one particularly troublesome spot.

“We’ll work on our kindergarten skills over here,” Mission Control replied, urging him to move on.

With more people and experiments flying on the space station, more power will be needed to keep everything running, according to NASA. The six new solar panels — to be delivered in pairs by SpaceX over the coming year or so — should boost the station’s electrical capability by as much as 30%.

Rubins and Glover worked on the struts for the first two solar panels, due to launch in June.

The eight solar panels up there now are 12 to 20 years old — most of them past their design lifetime and deteriorating. Each panel is 112 feet (34 metres) long by 39 feet (12 metres) wide. Tip to tip counting the centre framework, each pair stretches 240 feet (73 metres), longer than a Boeing 777’s wingspan.

Boeing is supplying the new roll-up panels, about half the size of the old ones but just as powerful thanks to the latest solar cell technology. They’ll be placed at an angle above the old ones, which will continue to operate.

A prototype was tested at the space station in 2017.

Rubins’ helmet featured a new high-definition camera that provided stunning views, particularly those showing the vivid blue Earth 270 miles (435 kilometres) below. “Pretty fantastic,” observed Mission Control.

Sunday’s spacewalk was the third for infectious disease specialist Rubins and Navy pilot Glover — both of whom could end up flying to the moon.

They’re among 18 astronauts newly assigned to NASA’s Artemis moon-landing program. The next moonwalkers will come from this group.

Last week, Vice-President Kamala Harris put in a congratulatory call to Glover, the first African American astronaut to live full time at the space station. NASA released the video exchange Saturday.

“The history making that you are doing, we are so proud of you,” Harris said. Like other firsts, Glover replied, it won’t be the last. “We want to make sure that we can continue to do new things,” he said.

Rubins will float back out Friday with Japanese astronaut Soichi Noguchi to wrap up the solar panel prep work, and to vent and relocate ammonia coolant hoses.

Glover and Noguchi were among four astronauts arriving via SpaceX in November. Rubins launched from Kazakhstan in October alongside two Russians. They’re all scheduled to return to Earth this spring.

Mars City design: 6 sci-fi cities that will blow your mind – Inverse

Published

 on


As Perseverance inspires the entire world about the thrill of visiting our nearest solar neighbor, Mars, it’s easy to start fantasizing about what it will be like when human beings regularly live on the red planet in the future.

Between SpaceX and NASA, it feels reasonable that human beings will be living on Mars before the end of the century. The question is when they do, what will the first Martian cities look like?

Science fiction should never be used as an actual forecast for human culture, but it is a lot of fun to think about how sci-fi stories have imagined our future lives on Mars. Here are six of the best very best Martian cities, ranked not in order of livability, but instead, but pure sci-fi coolness.

6. Bradbury City – Mars trilogy

Ray BradburyGetty

There are several fictional cities in Kim Stanely Robinson’s seminal SF books about the settlement of Mars — Red Mars, Green Mars, and Blue Mars — so it’s hard to pick just one. But, if you have to choose only one Martian metropolis from his books, Bradbury City is the way to go.

Named for Ray Bradbury, who wrote The Martian Chronicles, Robinson’s Bradbury City is designed to recreate a city in Illinois. Bradbury was born in Waukegan, Illinois. The Martian Chronicles features several unlikely Martian cities, some made by humans, some made by Martians. But, in almost all cases, like in “Night Meeting,” these towns and cities often have gas stations and pickup trucks.

5. Bowie Base One – Doctor Who

Not exactly a city per se, but certainly a great Martian settlement in the pantheon of science fiction — if only for its name.

In the 2009 David Tennant-era Doctor Who one-off, “The Water of Mars,” the Doctor battles a type of sentient alien water called “the Flood,” that turns people into water zombies. Bowie Base One, in the Who-canon, is the first human colony on Mars, which leads to many, many others. Obviously, it’s named for David Bowie and the song “Life on Mars.”

4. Utopia Planitia – Star Trek

Paramount/CBS

In the 24th Century-era of Trek, most of the best ships in Starfleet are built at the Utopia Planitia Shipyards in orbit of Mars. The Trek franchise rarely visited Mars, although the final episodes of Enterprise Season 4 — “Terra Prime” and “Demons” — had a lot of action on the Martian surface.

Both Star Trek: Picard and its prequel, “Children of Mars,” revealed that the shipyards weren’t just in orbit of Mars, but also on the ground, which meant that a huge civilization population lived and worked on Mars prior to the Sythn revolt in 2285.

3. Londres Nova – The Expanse

Mars in The Expanse.Amazon

More than any other contemporary science fiction series, The Expanse — both the books and the TV series — have made a convincing projection of what a future Martian colony might be like.

The capital city, Londres Nova, is sometimes called “New London.” In the reality of The Expanse, what makes the settlement of Mars so interesting is the way in which it eventually just becomes totally independent from the Earth to the point at which its government is basically in direct competition with Earth for the entire solar system’s resources. By the future time period of The Expanse, Mars is basically an alien planet, populated by humans.

2. Mars Dome One – Babylon 5

Somewhat unique among science fiction, Babylon 5 started off with a lead character who was born on Mars, Commander Jeffery Sinclair. In B5, being from Mars isn’t that weird, but the politics of Mars are integral to the overall story of the series.

Mars Dome One

Mars Dome One is the biggest city there, and yes, it’s a giant dome. But, Mars Dome One and other cities in Babylon 5 are fascinating because unlike Earth, there’s more of an underworld on Mars, including an underground railroad for rogue telepaths.

1. Chyrse – Total Recall

Mars in Total Recall.TriStar

The Martian city visited by Arnold Schwarzenegger’s Quaid is by far the most memorable Martian city in science fiction, even if it doesn’t make a whole lot of sense.

In the Philip K. Dick short story upon which Total Recall was based, “We Can Remember It For Your Wholesale,” the lead character never actually goes to Mars, at least not in the realtime of the story. The triumph of Chryse in Total Recall is the edgy naturalism of this future city. It’s sleazy, dirty, and dangerous.

Total Recall

Can you grab me a copy of Mars Today?TriStar

In Blade Runner, you’re told that humans have emigrated to a variety of other planets. Chryse in Total Recall is like the Martian city equivalent of Los Angeles in Blade Runner. You can basically imagine them existing in the same shared universe. Would author Philip K. Dick approve? Maybe!
