By JOYCE M. ROSENBERG and KEN SWEET AP Business WritersNEW YORK (AP) — Americans are likely to see more "for rent" signs in the coming months. That's because many businesses devastated by the coronavirus pandemic are expected to abandon offices and storefronts. The changes are happening because more employees are working from home, and more people are shopping online. The result could bring an end to the long boom in the nation's commercial real estate market. Hotels, restaurants and stores that closed in March have seen only a partial return of customers. Many of them may fail. Commercial landlords have reported an increase in missed rent payments. They expect vacancies to rise through the end of the year. 724

CHARLOTTE, N.C. (AP) — Bubba Wallace is leaving Richard Petty Motorsports at the end of the season. NASCAR's only full-time Black driver informed RPM of his decision Thursday. He will finish the final nine races in Petty's famed No. 43 car. Wallace posted a statement about his decision on Twitter.Wallace says, "this was not an easy decision as I have nothing but the utmost respect for Richard Petty and his family." 426

CAPE CANAVERAL, Fla. (AP) — The spacecraft team that brought us close-ups of Pluto will ring in the new year by exploring an even more distant and mysterious world.NASA's New Horizons spacecraft will zip past the scrawny, icy object nicknamed Ultima Thule (TOO-lee) soon after the stroke of midnight.One billion miles beyond Pluto and an astounding 4 billion miles from Earth (1.6 billion kilometers and 6.4 billion kilometers), Ultima Thule will be the farthest world ever explored by humankind. That's what makes this deep-freeze target so enticing; it's a preserved relic dating all the way back to our solar system's origin 4.5 billion years ago. No spacecraft has visited anything so primitive."What could be more exciting than that?" said project scientist Hal Weaver of Johns Hopkins University, part of the New Horizons team.Lead scientist Alan Stern of Southwest Research Institute in Boulder, Colorado, expects the New Year's encounter to be riskier and more difficult than the rendezvous with Pluto: The spacecraft is older, the target is smaller, the flyby is closer and the distance from us is greater.NEW HORIZONSNASA launched the spacecraft in 2006; it's about the size of a baby grand piano. It flew past Pluto in 2015, providing the first close-up views of the dwarf planet. With the wildly successful flyby behind them, mission planners won an extension from NASA and set their sights on a destination deep inside the Kuiper Belt. As distant as it is, Pluto is barely in the Kuiper Belt, the so-called Twilight Zone stretching beyond Neptune. Ultima Thule is in the Twilight Zone's heart.ULTIMA THULEThis Kuiper Belt object was discovered by the Hubble Space Telescope in 2014. Officially known as 2014 MU69, it got the nickname Ultima Thule in an online vote. In classic and medieval literature, Thule was the most distant, northernmost place beyond the known world. When New Horizons first glimpsed the rocky iceball in August it was just a dot. Good close-up pictures should be available the day after the flyby.ARE WE THERE YET?New Horizons will make its closest approach in the wee hours of Jan. 1 — 12:33 a.m. EST. The spacecraft will zoom within 2,200 miles (3,500 kilometers) of Ultima Thule, its seven science instruments going full blast. The coast should be clear: Scientists have yet to find any rings or moons around it that could batter the spacecraft. New Horizons hurtles through space at 31,500 mph (50,700 kph), and even something as minuscule as a grain of rice could demolish it. "There's some danger and some suspense," Stern said at a fall meeting of astronomers. It will take about 10 hours to get confirmation that the spacecraft completed — and survived — the encounter.POSSIBLY TWINSScientists speculate Ultima Thule could be two objects closely orbiting one another. If a solo act, it's likely 20 miles (32 kilometers) long at most. Envision a baked potato. "Cucumber, whatever. Pick your favorite vegetable," said astronomer Carey Lisse of Johns Hopkins. It could even be two bodies connected by a neck. If twins, each could be 9 miles to 12 miles (15 kilometers to 20 kilometers) in diameter.MAPPING MISSONScientists will map Ultima Thule every possible way. They anticipate impact craters, possibly also pits and sinkholes, but its surface also could prove to be smooth. As for color, Ultima Thule should be darker than coal, burned by eons of cosmic rays, with a reddish hue. Nothing is certain, though, including its orbit, so big that it takes almost 300 of our Earth years to circle the sun. Scientists say they know just enough about the orbit to intercept it.COMPARING FLYBYSNew Horizons will get considerably closer to Ultima Thule than it did to Pluto: 2,220 miles versus 7,770 miles (3,500 kilometers vs. 12,500 kilometers). At the same time, Ultima Thule is 100 times smaller than Pluto and therefore harder to track, making everything more challenging. It took 4 ? hours, each way, for flight controllers at Johns Hopkins' Applied Physics Lab in Laurel, Maryland, to get a message to or from New Horizons at Pluto. Compare that with more than six hours at Ultima Thule.WHAT'S NEXTIt will take almost two years for New Horizons to beam back all its data on Ultima Thule. A flyby of an even more distant world could be in the offing in the 2020s, if NASA approves another mission extension and the spacecraft remains healthy. At the very least, the nuclear-powered New Horizons will continue to observe objects from afar, as it pushes deeper into the Kuiper Belt. There are countless objects out there, waiting to be explored. 4591

CDC Director Robert Redfield suggested that the coronavirus pandemic could become even more dire in the fall, as the weather gets cold and people head indoors.As part of an interview with WebMD on Wednesday, Redfield said it is imperative to do four things to slow the spread of the coronavirus: Hand washing, social distancing, wearing a mask and avoiding large gatherings.“I’m not asking some of America to do it -- we all have to do it,” Redfield said.And if Americans do not follow these suggestions?"This could be the worst fall, from a public health perspective, we've ever had,” Redfield told WebMD.Redfield’s dire outlook comes as the US continues to top 1,000 coronavirus-related deaths reported on average each day, according to Johns Hopkins University. While as of late Thursday, there have been over 167,000 coronavirus-related deaths in the US, a New York Times analysis of death records throughout the US during the pandemic suggests that the true number of coronavirus-related deaths could be higher.While the seasonal flu is far less deadly than the coronavirus, Redfield hopes the pandemic will inspire more Americans to obtain a flu shot. Getting more Americans vaccinated could reduce the burden facing the health care system this fall.“Please don’t leave this important accomplishment of American medicine on the shelf,” Redfield said. “This is a year that I’m asking people to really think deep down about getting the flu vaccine.”Redfield hopes that the percentage of Americans who take a flu shot increases from 47% to 65% this fall.As for the origins of the pandemic, Redfield said a lack of cooperation with China complicated the US response to the virus. Redfield said the US requested to work with Chinese officials as early as January 3.“I think if we had been able to get in at that time, we probably would have learned quicker than we learned here,” Redfield said. 1903
