A vehicle mileage tax could be on the table in talks about how to finance the White House's expected multi-trillion-dollar infrastructure proposal, according to Transportation Secretary Pete Buttigieg. "When you think about infrastructure, it's a classic example of the kind of investment that has a return on that investment," he said. This is a jobs vision as much as it is an infrastructure vision, a climate vision and more." "A so-called vehicle-miles-traveled tax or mileage tax, whatever you want to call it, could be a way to do it," he said. Democrats have slowly pivoted away from a gasoline tax in favor of a mileage tax amid a simultaneous, climate friendly effort to encourage consumers to drive electric cars.

Pete Buttigieg speaks at the Senate Commerce, Science, and Transportation nomination hearings to examine his expected nomination to be Secretary of Transportation in Washington. The U.S. Senate on Tuesday confirmed Pete Buttigieg as Transportation secretary, handing the former presidential candidate a wide array of challenges — from President Joe Biden's environmental priorities to the Covid-19 pandemic. Buttigieg, the former mayor of South Bend, Indiana, last week easily won approval from the Senate Commerce, Science and Transportation Committee, following a largely friendly hearing. In its first two weeks, the Biden administration has already taken a hard line on transportation measures that aim to curb the spread of Covid-19. On Tuesday, the U.S. government started requiring passengers to wear masks on airplanes, trains, buses, ferries and other forms of transportation.

Twitter CEO Jack Dorsey said on Wednesday that banning President Donald Trump was the "right decision for Twitter," but admitted that the internet shouldn't be controlled by a handful of private companies. He wrote that if a company like Twitter makes a decision that people don't like, they can go elsewhere, creating an inherent check on its power. "This concept was challenged last week when a number of foundational internet tool providers also decided not to host what they found dangerous," Dorsey wrote. Dorsey said the inconsistent policies and lack of transparency undermine the efforts to create an open internet. "The reason I have so much passion for #Bitcoin is largely because of the model it demonstrates: a foundational internet technology that is not controlled or influenced by any single individual or entity," Dorsey wrote.

(Soprintendenza ABAP Verona via AP)SOAVE Archaeologists have briefly revealed a well-preserved mosaic floor of an ancient Roman villa first discovered almost a century ago near the northern Italian city of Verona. The recent discovery of two nearby mosaic floors confirmed the villa extended north and south of the original site. The unearthed mosaic from the villa's servants' quarters dates from the 3rd century and has since been covered back up. The city said archaeological officials would decide with landowners and Negrar officials the best way to make the site accessible to the public.

SpaceX pressed ahead with its second attempt to launch astronauts for NASA a historic first for a private company but more stormy weather threatened more delays. Elon Musks company came within 17 minutes Wednesday of launching a pair of NASA astronauts for the first time in nearly a decade from the U.S., before the threat of lightning forced a delay. NASA Administrator Jim Bridenstine said managers were debating whether to bump the next launch attempt from Saturday to Sunday to take advantage of a slightly improved forecast at Kennedy Space Center. The Kennedy Space Center Visitor Complex reopened Thursday, after a 2 1/2-month shutdown, and within a few hours, all 4,000 tickets were snapped up for Saturdays launch attempt.

(AP Photo/David J. Phillip)CAPE CANAVERAL, Fla. A SpaceX rocket is ready to boost two NASA astronauts into orbit Wednesday, the first launch of Americans from the U.S. in nearly a decade. Riding aboard the brand new SpaceX Dragon capsule for the historic flight: veteran NASA astronauts Doug Hurley and Bob Behnken. SpaceX is controlling the vehicle, theres no fluff about that, said Norm Knight, a NASA flight operations manager. The last time astronauts launched from Florida was on NASAs final space shuttle flight in July 2011. Development of SpaceXs Dragon and Boeings Starliner capsules took longer than expected, however, and the U.S. has been paying Russia to launch NASA astronauts in the interim.

CAPE CANAVERAL, Fla. NASA is rolling out the International Space Stations red carpet for Tom Cruise to make a movie in orbit. Bridenstine said hell leaving it to Cruise and SpaceX to provide the mission details. I will tell you this: NASA has been in talks with Tom Cruise and, of course, his team, and we will do everything we can to make it a successful mission, including opening up the International Space Station," he told The Associated Press. Asked about Cruise filming on the space station, Musk told CBS This Morning, Actually, I think that remains to be seen. The question is, Can Tom Cruise make a new movie that inspires the next generation Elon Musk. And if he can do that, then were all for it.

For the spectators gathered along the Space Coast on Wednesday for an astronaut launch, the rumbling thunder and darkening clouds were more worrisome than any pandemic. They turned out to watch the first launch with astronauts from Florida in almost a decade, and the first by a private company, SpaceX. About half of the spectators at the Titusville park wore masks as encouraged by health officials to stop the spread of the new coronavirus. I wanted them to see the flip side and get to see the next era of space travel," said Gatz, who lives about an hour away in Deltona.

(AP Photo/Susan Walsh)WASHINGTON President Donald Trump is hoping the first launch of American astronauts from U.S. soil in nearly a decade will give the nations spirit a boost after months of battling the coronavirus. Its the latest visit to an important 2020 battleground state as the president emerges from his White House bubble and expands his travel itinerary. Trump is encouraging states to loosen restrictions on economic activity put into place to slow the spread of the coronavirus. A Quinnipiac University poll last month found older Florida voters divided on Trumps handling of the coronavirus outbreak, with 47% saying they approved and 50% disapproving. Vice President Mike Pence got to Florida ahead of Trump and was to meet with the astronauts families and NASA officials before the launch.

DENVER Nearly two dozen states and several cities on Wednesday filed a legal challenge to the Trump administrations rollback of Obama-era mileage standards, saying science backed up the old regulations developed with the help of the nation's car makers. The new mileage standards require automakers to achieve 1.5% annual increases in fuel efficiency. The Obama-era standards called for 5% annual increases and were seen as the government's most forceful initiative against climate-changing fossil fuel emissions. The states and cities claim the rule violates the Clean Air Act, the Energy Policy and Conservation Act and the Administrative Procedure Act. Opponents claim dirtier air from the rollback will kill and injure more people than the rollback claims to save in roadway accidents.

CAPE CANAVERAL, Fla. Stormy weather is threatening to delay SpaceXs first astronaut launch. It will be the first time astronauts launch from Florida in nine years and a first for a private company. We're continuing to be vigilant and careful and make sure we do this right.Forecasters put the odds of acceptable launch weather at 40%. Hans Koenigsmann, a vice president for SpaceX, said the launch control team will incorporate global weather patterns and models to determine whether it's safe to launch. If the weather gods are working with us," he said, liftoff will occur at 4:33 p.m. SpaceX has a split-second launch window.

Veteran NASA astronauts Doug Hurley and Bob Behnken were set to make history Wednesday afternoon, riding SpaceX's Falcon 9 rocket and Dragon capsule to the International Space Station on a test flight. On the eve of the launch, NASA Administrator Jim Bridenstine said from Kennedy Space Center that both the space agency and SpaceX have been diligent about making sure everyone in the launch loop knows they're free to halt the countdown if there's a concern. SpaceX has been launching cargo capsules to the space station since 2012. NASA hired SpaceX and Boeing in 2014 to transport astronauts to the space station, after commercial cargo shipments had taken off. Development of SpaceX's Dragon and Boeing's Starliner capsules took longer than expected, however, and the U.S. has been paying Russia to launch NASA astronauts in the interim.

Blood clots that can cause strokes, heart attacks and dangerous blockages in the legs and lungs are increasingly being found in COVID-19 patients, including some children. Some hospitals have found 40% of deaths in COVID-19 patients are from blood clots. Spyropoulos said thats been true at his 23-hospital system in the New York City area, Northwell Health, which has treated over 11,000 COVID-19 patients. Some COVID-19 patients, like Gildersleeve, develop dangerous clots when their infections seem to have subsided, Spyropoulos said. Concerns about blood clots in COVID-19 patients prompted a recent 30-page consensus statement from an international group of physicians and researchers.

CAPE CANAVERAL, Fla. Its back to the future as NASA astronauts launch again from the U.S. aboard a retro-style Right Stuff capsule. SpaceXs Dragon crew capsule outshines NASAs old Apollo spacecraft in virtually every way. This fresh take on a vintage look will be on full display Wednesday when SpaceX plans to launch NASA astronauts Doug Hurley and Bob Behnken to the International Space Station a first for a private company. A SpaceX Falcon 9 rocket with the crew capsule atop will soar from the same pad used for both of those earlier missions. Russias workhorse Soyuz capsules, still in use after a half-century plus, have kept NASA astronauts flying to the space station.

Starting with the dream of growing a rose on Mars, Musks vision morphed into a shake-up of the old space industry, and a fleet of new private rockets. But for Musks company, SpaceX, its also the latest milestone in a wild ride that began with epic failures and the threat of bankruptcy. There are many space companies and like all of them, SpaceX is designed for profit. The idea of bigger roles for private companies has been around for more than 50 years, but the market and technology werent yet right. A 2005 pilot project helped private companies develop ships to bring cargo to the station.

(SpaceX via AP)CAPE CANAVERAL, Fla. The two astronauts who will test drive SpaceXs brand new rocketship are classmates and friends, veteran spacefliers married to veteran spacefliers, and fathers of young sons. Retired Marine Col. Doug Hurley will be in charge of launch and landing, a fitting assignment for the pilot of NASAs last space shuttle flight. Hurley, 53, and Behnken, 49, are NASAs first test pilot crew in decades. Crippen and the late John Young rode NASAs first space shuttle, Columbia, into orbit on April 12, 1981. Hurley and Behnken both two-time space shuttle fliers were among four astronauts chosen in 2015 for NASAs commercial crew program.

(AP Photo/Dave Martin)ORLANDO, Fla. In ordinary times, the beaches and roads along Floridas Space Coast would be packed with hundreds of thousands of spectators, eager to witness the first astronaut launch from Florida in nine years. Earlier this month, NASA Administrator Jim Bridenstine asked potential spectators to watch the launch online or on TV from home. NASA astronauts have not launched from the U.S. since the space shuttle program ended in 2011. Although crowd sizes varied, a high-profile space shuttle launch could attract a half million visitors to the Space Coast.
