With this critical test finally finished, NASA now will send the rocket segment to Kennedy Space Center for launch preparations. (NASA via AP)CAPE CANAVERAL, Fla. – NASA completed an engine test firing of its moon rocket Thursday, after the first attempt in January ended prematurely. This time, the four main engines of the rocket’s core stage remained ignited for the full eight minutes. John Honeycutt, NASA's program manager for the Space Launch System or SLS rocket, said everything seemed to go well in Thursday's test firing. The SLS rocket will send an empty Orion capsule to the moon and back.

The first woman and next man on the moon will come from this elite group. Vice President Mike Pence introduced the astronauts Wednesday at the close of his final meeting as chairman of the National Space Council. The space agency is aiming for a moon landing by 2024, although the chances of that happening are growing increasingly dim. Half of the NASA astronauts have spaceflight experience. “The history is awesome, but we’re here to look toward the future,” Acaba told reporters after the announcement.

The Dragon — packed with Christmas treats and presents — should reach the space station on Monday, joining the Dragon that delivered four astronauts last month. “Dragons everywhere you look,” said Kenny Todd, NASA’s deputy space station program manager. With NASA’s commercial crew program officially under way, SpaceX expects to always have at least one Dragon capsule at the space station. The station crew watched a live broadcast of the launch, from 250 miles (400 kilometers) up. This updated cargo-carrying model — as large as the SpaceX crew capsule — will dock to the orbiting lab by itself.

In this frame grab from NASA TV, the SpaceX Dragon is seen after docking at the International Space Station, late Monday, Nov. 16, 2020. (NASA TV via AP)CAPE CANAVERAL, Fla. – SpaceX’s newly launched capsule with four astronauts arrived Monday at the International Space Station, their new home until spring. The Dragon capsule pulled up and docked late Monday night, following a 27-hour, completely automated flight from NASA's Kennedy Space Center. “Oh, what a good voice to hear,” space station astronaut Kate Rubins called out when the Dragon's commander, Mike Hopkins, first made radio contact. And so it will go, with SpaceX — and eventually Boeing — transporting astronauts to and from the station for NASA.

The three Americans and one Japanese should reach the International Space Station late Monday for a five- to six-month stay, following Sunday's liftoff from NASA's Kennedy Space Center. A brief look at each:—Crew commander Mike Hopkins, 51, is an Air Force colonel and former space station resident who grew up on a hog and cattle farm in Missouri. He played football for the University of Illinois and, before becoming an astronaut in 2009, worked at the Pentagon. —Shannon Walker, 55, a Houston-born-and-raised physicist, also has lived before on the space station. She worked as a flight controller at NASA’s Johnson Space Center and then behind the scenes in the space station program, before becoming an astronaut in 2004.

With COVID-19 still surging, NASA continued the safety precautions put in place for SpaceX’s crew launch in May. Even the two astronauts on the first SpaceX crew flight stayed behind at Johnson Space Center in Houston. “I didn’t start breathing until about a minute after it took off,” Pence said during a stop at SpaceX Launch Control to congratulate the workers. Similar pleas for SpaceX’s first crew launch on May 30 went unheeded. The first-stage booster is expected to be recycled by SpaceX for the next crew launch.

Friday’s postponement news came after SpaceX chief Elon Musk disclosed he had gotten mixed test results for COVID-19 and was awaiting the outcome of a more definitive test. “I can assure everyone that we’re looking good for the (crew) launch and all of the critical personnel involved,” said SpaceX’s Benji Reed, senior director for human spaceflight. “So ‘Elon Musk Tests Negative for Covid’ is an equally correct title,” he tweeted. The upcoming crew flight comes just three months after the end of the test flight with Hurley and Bob Behnken, both NASA astronauts. NASA and SpaceX are especially eager to retrieve this first-stage booster; it will be used for the next crew launch.

That means most college students today have never known a day without an astronaut orbiting above them on the International Space Station. The International Space Station, or ISS, is just shy of the same length as an American football field and the largest spacecraft ever built. “I felt as an International Space Station, we needed to enter as an international crew.”AdCabana and Krikalev went into the ISS at the same time. “Sergei and I enter side by side, so there was no first person to enter the International Space Station,” Cabana said. Hosted by space reporter Emilee Speck, each episode is designed to inspire everyone, from the space curious to the space fanatics.

Let’s be serious, we’re all in a space mood after watching NASA astronauts launch from Kennedy Space Center last month. Whether you’re taking your shuttle out for a Sunday drive, taking a road trip, or blasting off to the stars -- a playlist is absolutely necessary to make the trip memorable. NASA Astronauts Bob Behnken and Doug Hurley made a playlist for their 3-mile ride to Launch Complex 39A before liftoff. You’ll hear melodies like “Space Oddity”, “Rocket Man” as well as “A Sky Full of Stars” made famous by Coldplay. Buckle up and don your space suit -- or whatever NASA apparel you have close by, as we dive into our space jams.

If it goes off as planned, this will mark the first mission involving astronauts from U.S. soil since 2011. Still, NASA astronaut Bob Behnken has said he and Doug Hurley are “really comfortable” with the risks. So you’re making educated guesses, at best.”It seems there’s just more uncharted territory when it comes to space travel. “The first astronauts really started out as test pilots,” Garfinkle said. But assuming this launch goes well, “It would be great for kids to see a successful, triumphant moment of science,” Fink said.

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.

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/David J. Phillip)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.

(Bill Ingalls/NASA via AP)STERLING, Va. President Donald Trump plans to be on the Florida coast Wednesday to watch American astronauts blast into orbit from the Kennedy Space Center for the first time in nearly a decade. It will be the first time since the space shuttle program ended in 2011 that U.S. astronauts will launch into space aboard an American rocket from American soil. Elon Musks SpaceX is the conductor and NASA the customer as businesses begin chauffeuring astronauts to the International Space Station. The NASA/SpaceX Commercial Crew flight test launch will carry NASAs newest test pilots, Doug Hurley and Bob Behnken, in a SpaceX Crew Dragon capsule on a SpaceX Falcon 9 rocket. Vice President Mike Pence, who is chairman of the National Space Council, also plans to attend Wednesday's launch.

CAPE CANAVERAL, FL The Air Force's mystery space plane is back on Earth, following a record-breaking two-year mission. The X-37B landed at NASA's Kennedy Space Center in Florida early Sunday. The Air Force is mum about what the plane did in orbit after launching aboard a SpaceX rocket in 2017. Experiments from the Air Force Research Laboratory were aboard. 6 is planned next year with another launch from Cape Canaveral.
