The Demo-2 mission represents a new era for American spaceflight.
- On Wednesday afternoon, SpaceX is set to become the first private company to launch humans into orbit.
- The company's Crew Dragon, launched by the Falcon 9 rocket, is scheduled to take two NASA astronauts to the International Space Station.
- Neil deGrasse Tyson will host the American Museum of Natural History's live-stream coverage of the launch.

But the company has also suffered setbacks with the capsule, including thruster and parachute complications, and a <a href="https://www.wired.com/story/a-leaky-component-caused-the-spacex-crew-dragon-explosion/" target="_blank">2019 explosion that occurred during testing</a>.</p><p>If successful, Falcon 9 will launch the Dragon capsule into low Earth orbit 12 minutes after takeoff. The rocket will then begin a controlled descent to its landing site on a drone ship in the Atlantic Ocean. Hurley and Behnken will manually fly Crew Dragon toward the ISS.</p><p>When they approach the station, Crew Dragon's autonomous docking system will take over, and the capsule will connect to the station at 11:29 a.m. on Thursday. The NASA astronauts will then board the ISS, where they'll likely remain for several months. (NASA has yet to confirm the details of the return mission.)</p>

Started in 2010, the federally funded program aims to pair NASA with private companies — like SpaceX and Boeing — to transport astronauts to and from the ISS. The mission also represents the end of an era in which the U.S. has relied on Russia to transport American astronauts to the ISS.</p><p style="margin-left: 20px;">"This is a unique opportunity to bring all of America together in one moment in time and say, look at how bright the future is," Jim Bridenstine, NASA's administrator, <a href="https://www.nytimes.com/2020/05/26/science/spacex-launch-nasa.html" target="_blank">said</a> at a news conference on Tuesday.</p><p><strong>Here's where you can live-stream the historic launch:</strong><br></p>

The 57-year-old is teaming up with NASA and SpaceX for the film project, which is to be set aboard the International Space Station.
- NASA Administrator Jim Bridenstine confirmed the project on Tuesday via Twitter.
- The project — an action-adventure movie — would be the first narrative film shot in space.
- It's unclear how Cruise will get to the space station. Later this May, SpaceX and NASA plan to send American astronauts to the ISS aboard a SpaceX vehicle.
NASA's SpaceX Demo-2 mission will return U.S human spaceflight to the International Space Station from U.S. soil with astronauts Robert Behnken and Douglas Hurley on an American rocket and spacecraft for the first time since 2011<p>Here's how <a href="https://www.nasa.gov/specials/dm2/" target="_blank">NASA describes</a> the upcoming Demo-2 flight:</p><p style="margin-left: 20px;">"After successfully docking, [astronauts] Behnken and Hurley will be welcomed aboard [the] station and will become members of the Expedition 63 crew," NASA wrote on its website. "They will perform tests on Crew Dragon in addition to conducting research and other tasks with the space station crew.</p><p style="margin-left: 20px;">Upon conclusion of the mission, Crew Dragon will autonomously undock with the two astronauts on board, depart the space station and re-enter the Earth's atmosphere. Upon splashdown just off Florida's Atlantic Coast, the crew will be picked up at sea by SpaceX's Go Navigator recovery vessel and return to Cape Canaveral."</p>
Axiom Space<p>In January, NASA and a startup called Axiom Space <a href="https://bigthink.com/politics-current-affairs/space-tourism" target="_blank">announced plans</a> to attach what's essentially a "space hotel" to the ISS, and to sell trips to non-astronauts. It would be a major step in the agency's years-long push to privatize the aging station. </p><p>Axiom has already lined up its first customer. The ticket cost? An estimated <a href="https://www.nytimes.com/2020/03/05/science/axiom-space-station.html" target="_blank">$55 million</a>, the bulk of which comes from the steep cost of the rocket launch. But it's not much cheaper once you get to the station — a <a href="https://www.nasa.gov/sites/default/files/atoms/files/s1701746119060610280_1.pdf" target="_blank">2019 NASA report</a> shows that the cost of life-support equipment alone is about $11,250 per day. </p><p>So, though much remains unclear about Cruise's upcoming film project, what's certain is that shooting it will require an astronomically huge budget.</p>
Astronauts aren’t floating in space, they’re free falling—and so are you. Here's the amazing science behind so-called zero gravity.
When we launched our 'Ask an astronomer' series with NASA's Michelle Thaller, one set of questions stood out from hundreds, arriving by way of the curious and clever students at Courthill Infant School, Poole, in the south of England. Representing all the aspiring scientists in Dragonflies Class, Joshua, age 4, asked NASA's Michelle Thaller a brilliant question: "Why is there no gravity in space?" Here, Thaller explains the incredible science behind why astronauts appear to float in space, which is an interesting misconception fuelled by the term 'zero gravity'. (In fact, there is a small amount of gravity found everywhere in space, which is why microgravity is a more accurate term.) So what are they doing if not floating? They're actually constantly free falling, says Thaller, and so are you, the person beside you, and the entire planet Earth. It's a high-velocity orbit that allows astronauts to seemingly defy gravity, soaring so fast around the planet that they remain suspended instead of succumbing to Earth's gravitational pull. Michelle Thaller explains the very cool science of how orbits allow astronauts to seemingly defy gravity. You can follow Michelle Thaller on Twitter at @mlthaller.
Think getting along with people that are nothing like you is hard? Here’s how astronauts do it, 254 miles above Earth on the ISS.
Look up—you can see the greatest feat of human cooperation orbiting 254 miles above Earth. As commander of Expedition 35 aboard the International Space Station (ISS), Canadian astronaut Chris Hadfield understands the difficulty of cultural barriers in team work, and the life or death necessity of learning to communicate across those divides. The ISS is a joint project between five space agencies, built by people from 15 different nations—and each of them has a different take on what is "normal". Hadfield explains the scale of cultural differences aboard the spaceship: "What do you do on a Friday night? What does "yes" mean? What does "uh-huh" mean? What is the day of worship? When do you celebrate a holiday? How do you treat your spouse or your children? How do you treat each other? What is the hierarchy of command? All of those things seem completely clear to you, but you were raised in a specific culture that is actually shared by no one else." Here, Hadfield explains his strategy for genuine listening and communication. Whether it's money, reputation, or your life that's at stake, being sensitive and aware of people's differences helps you accomplish something together—no matter where you’re from. Amway believes that diversity and inclusion are essential to the growth and prosperity of today’s companies. When woven into every aspect of the talent life cycle, companies committed to diversity and inclusion are the best equipped to innovate, improve brand image and drive performance. Chris Hadfield features in the new docuseries One Strange Rock and is the author of An Astronaut's Guide to Life on Earth: What Going to Space Taught Me About Ingenuity, Determination, and Being Prepared for Anything
Space is not the place to put waste, as it turns pretty much anything into a high-velocity projectile capable of causing incredible damage.
Space isn't as spacious as it should be; it's full of space debris, small amounts of scrap, trash, and machinery that humans have abandoned to Earth's orbit. The ISS has cataloged about 500,000 of these small pieces and they hurtle around our planet at about 15,000mph. Or 14.17 g-force. Or 24,140kph.
