WATCH: Neil deGrasse Tyson to commentate SpaceX's historic mission to ISS
The Demo-2 mission represents a new era for American spaceflight.
27 May, 2020
- 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.
<p>On Wednesday afternoon, a SpaceX rocket is set to launch two NASA astronauts into space on a mission to the International Space Station. If successful, it'll be the first time a private company has put humans into orbit, and the first time astronauts have launched from American soil since NASA's Space Shuttle program ended in 2011.</p>
<p>At 4:33 p.m E.T., SpaceX's Falcon 9 rocket is set to take off from the company's Launch Complex 39A site in Cape Canaveral, Florida. About 90 minutes before launch, NASA astronauts <a href="https://www.theverge.com/2020/5/20/21254315/spacex-crew-dragon-astronauts-behnken-hurley-nasa-launch-dm-2" target="_blank">Bob Behnken and Doug Hurley</a> will walk across a walkway 230 feet above the ground and climb into Crew Dragon — the SpaceX capsule that sits atop the Falcon 9 rocket.</p>

<p>It won't be the Crew Dragon's first mission. Last year, SpaceX successfully sent a Crew Dragon carrying only cargo to the International Space Station. 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><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzMyNDM4OS9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYwMTI0OTMxMX0.xVUwsIR1TMHgOp9hzMW7lndhJLA9aZP6Mv_14TCzFUc/img.png?width=980" id="2d9fb" class="rm-shortcode" data-rm-shortcode-id="1b0faf562e9dde3678d9d0eb028cd936" data-rm-shortcode-name="rebelmouse-image" alt="Crew Dragon" />

<p>In addition to being a milestone for private spaceflight, Wednesday's mission — called Demo-2 — is also the culmination of NASA's Commercial Crew Program. 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>American Museum of Natural History

Why Elon Musk hopes the Falcon Heavy launch will spark ‘new space race’
SpaceX CEO Elon Musk is encouraging aerospace companies to up their game after successfully launching the most powerful rocket since NASA's Saturn V.

Massive Poster Details Humanity's Missions Through the Universe So Far
A massive chart of humankind’s 113 spacecraft so far and where they’ve gone.
04 December, 2016
Chart of Cosmic Exploration
By our count, there are 113 spacecraft in this image. It’s a catalogue of all of the vehicles launched into space so far, from the U.S.S.R’s Luna 2 in 1959 to the U.S.’s DSCOVR in 2015. Every orbiter, lander, rover, flyby, and impactor is here, along with its trajectory. It’s actually an image of a physical poster from PopChart Lab that any space maven could spend some quality time with.

(If you’re on your phone, you may want to bookmark this and check it out when you’re near a big screen.)</p> <h2>About the Trajectories</h2> <p>Each one is numbered here, and there’s a box below with the same number showing the craft that have traveled that route. There are direct routes, and there’s tons of gravitational slingshotting around celestial bodies that provides a craft momentum en route to a more distant destination like Pluto. In some cases, that involves involves multiple orbits around a nearby (relatively speaking) body — check out all the action around giant Jupiter, centrally located and capable of providing some powerful gravitational oomph.</p> <p><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xODQwOTA3OC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYxMDI0OTQ3Nn0.eXSZsF_6tfQ4-LQ-nZKXC4KPrh-yTjEWUYfNuwglJW4/img.jpg?width=980" id="e40a1" class="rm-shortcode" data-rm-shortcode-id="c3123e5cbba2ecfddc5529eff98e7f3e" data-rm-shortcode-name="rebelmouse-image"></p> <p>It’s a little hard to keep the flight paths separate visually. There’s a lot of overlap because the countries plotting the courses of these spaceships go with what works, and the math involved is hardly trivial — hey, it <em>is</em> rocket science.</p> <p>Here’s a little taste of what’s in this amazing image.
