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.

The spacecraft is set to launch from the Kennedy Space Center in Florida at 10:17 a.m., Sunday, and will deliver supplies to the ISS. According to NASA, some of the supplies that will be delivered will help further the ongoing research projects at the space station.

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.

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.

CAPE CANAVERAL, Fla. – SpaceX launched four astronauts to the International Space Station on Sunday on the first full-fledged taxi flight for NASA by a private company. It is due to reach the space station late Monday and remain there until spring. NASA policy at Kennedy Space Center requires anyone testing positive for coronavirus to quarantine and remain isolated. Even the two astronauts on the first SpaceX crew flight stayed behind at Johnson Space Center in Houston. NASA turned to private companies to haul cargo and crew to the space station, after the shuttle fleet retired in 2011.

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.
