MUSK MAKES HISTORY: SpaceX just launched 2 people into orbit for the first time, kicking off the rocket company's most important mission since its founding 18 years ago
SpaceX has successfully launched into orbit its first human passengers: NASA astronauts Bob Behnken and Doug Hurley.
The astronauts lifted off at 3:22 p.m. ET on Saturday while riding inside Crew Dragon, a new privately developed spaceship that Elon Musk's rocket company made in part for NASA.
However, the Demo-2 mission is a test flight that's far from over. Behnken and Hurley could spend up to 110 days in space after they reach and dock with the International Space Station.
Garrett Reisman, a former astronaut who worked on SpaceX's Dragon vehicles, said success for Demo-2 could spark a golden age of commercial spaceflight.
CAPE CANAVERAL — Amid the threat of rain and lightning on Saturday, one of SpaceX's Falcon 9 rockets heaved itself off the ground at 3:22 p.m. ET with a thunderous roar of flames, smoke, and dust.
Then, about 12 minutes later, a relatively small payload popped off the top of the 23-story launcher while moving close to 17,500 mph, slipping the spacecraft into low-Earth orbit.
However, this payload is unlike anything the world has seen: a privately developed commercial spaceship called Crew Dragon, which is carrying SpaceX's first human passengers — NASA astronauts Bob Behnken and Doug Hurley.
Shortly before their historic crewed space launch, the first from American soil since July 2011, the men shared ceremonious words from SpaceX's Crew Dragon spaceship over the radio.
"It is absolutely an honor to be part of this huge effort to get the United States back in the launch business," Hurley said, minutes before liftoff.

The NASA administrator, Jim Bridenstine, became emotional while delivering remarks after the crew reached orbit.
"I'm breathing a sigh of relief, but I will also tell you I'm not going to celebrate until Bob and Doug are home safely," Bridenstine said, adding: "I've heard that rumble before, but it's a whole different feeling when it's your team on top of that rocket."
Elon Musk, who founded SpaceX in 2002, expressed his enthusiasm during the first launch attempt on Wednesday: "This is a dream come true for me and everyone else at SpaceX."
"I didn't even dream that this would come true."
Poor weather threatened to delay the mission a second time, as clouds crowded the Florida skies and teased rocket-threatening lightning. A rain shower briefly soaked the rocket.
Similar conditions forced NASA and SpaceX to scrub their first launch attempt just 17 minutes before liftoff on Wednesday, since the Falcon 9 rocket could trigger lightning strikes from electrically charged clouds.
Though the historic mission is on its way, the hard part is not over for the two men, SpaceX, or NASA — a partner that has invested more than $3.14 billion to foster the system's development.
Launching rockets is something SpaceX excels at, with now 86 successful liftoffs under its belt. Flying crewed space capsules and keeping the passengers alive is another matter.
To prove to NASA and the rest of the world it can be done, the astronauts will spend the next day catching up to the International Space Station, where they will dock the new spaceship for about 110 days before returning home.
The stakes are enormous, with the success of the mission — marked by a safe landing in the Atlantic Ocean off the coast of Florida — bound to shape the future of SpaceX, NASA, and human spaceflight in general.
A 3-month spaceflight to tame the Dragon
The sun rises in Cape Canaveral, Florida, as SpaceX's Crew Dragon spaceship and Falcon 9 rocket await launch in May 2020.
Now in orbit, Behnken and Hurley will climb out of their spacesuits, get a bite to eat, and begin to test out as many systems on Crew Dragon as they can — including overriding the spaceship's automated controls to pilot the vehicle. They also plan to try out the toilet (which is shrouded in proprietary mystery) and eventually get some sleep inside the vehicle.
"We're just excited to kind of put it through its paces," Hurley said during a press briefing on May 1.
Within a day of launch, the ship will pull up to the International Space Station (ISS): SpaceX and NASA's ultimate, football field-size destination in orbit. Behnken and Hurley will try their hand at the manual docking controls before turning the automated system back on.
If the procedure goes well, NASA says the ship should berth on Sunday at 10:27 a.m. ET and the hatches between the ship and the space station should open around 12:45 p.m. ET. The three-person crew of the station's Expedition 63, commanded by fellow NASA astronaut Chris Cassidy, will be waiting to greet Behnken and Hurley.
Although the Crew Dragon's final version is designed to stay in space for nearly seven months, NASA and SpaceX said this particular ship could stay up to 110 days. That shelf life, they said, is determined by the ship's solar panels; over time, a corrosive form of oxygen high above Earth will degrade the panels.
"That schedule is a little bit in flux," Hans Koenigsmann, SpaceX's vice president of mission assurance, said during a May 25 briefing. "NASA will tell us when we're ready to go."
The crews of STS-135 and Expedition 28 hold up a US flag that flew on the first space shuttle mission, STS-1, returned to Earth, and flew again on STS-135. The flag was left on the International Space Station for the next crewed launch from American soil.
Before Behnken and Hurley leave the ISS, though, they'll grab a historic memento: an American flag flown on the first space shuttle mission and left by the crew of NASA's 135th and final space shuttle flight, of which Hurley was a member.
That competition is now down to SpaceX and Boeing, which is slated for a crewed test flight of its CST-100 Starliner spaceship in early 2021.
"We definitely feel like we're in the lead to make it to the International Space Station and retrieve the flag that STS-135 left behind. But we aren't really focused on who's going to win and who's going to lose," Behnken told reporters on May 1.
He added: "We're really focused on making sure that we technically get into space and get this vehicle checked out and accomplish the ultimate mission, which isn't winning against Boeing: It's providing this capability to the International Space Station so that we can start rotating crews from American soil."
Elon Musk is most worried about the landing of Crew Dragon

When the astronauts are ready to return, they'll climb back into Crew Dragon, put on their spacesuits, and undock from the space station. Then they'll get into position to blast off the spaceship's thrusters, allowing Earth's gravity to pull them back to the planet.
This reentry of the space capsule through Earth's atmosphere — aside from the threat posed by space debris — is the "biggest concern" for Musk, he told Irene Klotz of Aviation Week.
His worry concerning the new spaceship was the capsule's asymmetric design, which is driven by its emergency escape system. While screaming back to Earth at 25 times the speed of sound, the capsule's heat shield will deflect and absorb the energy of superheated plasma — but the forces of atmospheric reentry have a slim chance of causing catastrophic issues, Musk said.
"If you rotate too much, then you could potentially catch the plasma in the super Draco escape thruster pods," Musk said, adding this could overheat parts of the ship or cause it to lose control (by wobbling). "We've looked at this six ways to Sunday, so it's not that I think this will fail. It's just that I worry a bit that it is asymmetric on the backshell."
After slowing down due to drag, Crew Dragon is supposed to open its parachutes and splash down in the Atlantic Ocean off the coast of Florida, where recovery boats will pick up the astronauts. Koenigsmann told Business Insider that is a concern, since the parachute packing can't really be tested before launch, but that the risk of failure is very low due to scores of tests performed by SpaceX.
In all likelihood, according to NASA and SpaceX's risk estimates, the mission has more than a 98% chance of success and even higher odds of keeping Behnken and Hurley safe. NASA estimated the chance SpaceX might lose the spaceship during the landing phase to be less than 1 in 500.
The 'beginning of a golden age of commercial spaceflight'
The sun sets in Cape Canaveral, Florida, as SpaceX's Crew Dragon spaceship and Falcon 9 rocket await launch in May 2020.
Assuming all goes well from start to finish with the Demo-2 mission, experts believe the mission could represent a bold new era for human spaceflight.
Former NASA astronaut Garrett Reisman, who worked for many years on SpaceX's cargo and crewed spaceship programs, said Crew Dragon and Demo-2 could signal major progress within the spaceflight industry.
For one, he said, it'd be "the ultimate validation" of NASA's decision to split roughly $8 billion between SpaceX and Boeing and have the companies develop their own spacecraft and, in the end, privately own and operate them. That model contrasts with the agency's Orion spaceship and Space Launch System rocket programs, which NASA will own and operate but have amounted to tens of billions of dollars in taxpayer costs without a single test launch.
"I think that the combination of those two things — the performance plus the cost savings — would be an incredible validation and endorsement of this whole approach," Reisman said.
Put together, he said success for Demo-2 would represent "the beginning of a golden age of commercial spaceflight."
"We would be within a year of flying ordinary citizens in space, and that will be hugely transformative," he added.

Reisman says that at first only the wealthy and well-connected will have access to space. But he added that the early days of commercial aviation looked very similar, with passengers spending inordinate sums to fly in biplanes while wearing tuxedos because it was such a rare event.
"That's where we're at with space travel today, we're in the very beginning stages," he said. "We have to look forward to the day when we have Southwest and JetBlue."
"The day will come when when everybody that wants to go to space will, for the most part, be able to afford to go," Reisman said.
SpaceX is hard at work on a follow-up crewed launch called Starship, which Musk hopes can reduce the cost of access to space by 1,000-fold or more.
Here’s what Russia’s 2020 disinformation operations look like, according to two experts on social media and propaganda. By DARREN LINVILL & PATRICK WARREN Internet trolls don’t troll. Not the professionals at least. Professional trolls don’t go on social media to antagonize liberals or belittle conservatives. They are not narrow minded, drunk or angry. They don’t lack basic English language skills. They certainly aren’t “somebody sitting on their bed that weighs 400 pounds,” as the president once put it. Your stereotypical trolls do exist on social media, but the amateurs aren’t a threat to Western democracy. Professional trolls, on the other hand, are the tip of the spear in the new digital, ideological battleground. To combat the threat they pose, we must first understand them — and take them seriously.

The Nightmare Scenario That Keeps Election Lawyers Up At Night -- And Could Hand Trump A Second Term (Photo: Photos: Getty Images) Americans will almost certainly go to bed on Nov. 3 without knowing who won the presidential election. Since millions of people will vote by mail, constraints on time and resources will slow ballot counting into potentially a weeks-long process. Voting patterns suggest it’s likely that President Donald Trump could end Election Day in the lead in certain key states, only to be overtaken by Democratic opponent Joe Biden when more votes are tallied. This could create a nightmare scenario during the three months stretching from Election Day to the Jan. 20 inauguration: a battle on the state and congressional level over who is the legitimate winner. This could include Congress reconvening on Jan. 6, presided over by Vice President Mike Pence , with no consensus over its potential role in choosing the next president. This...
It's like this folks: sometimes your mind goes blank. Happens more than usual with me of course. Take this forum for instance. I wanted to post something today and couldn't think of a topic. At least not a non-sexual one and we know sexual ones lately have been frowned upon. Then along comes one of our regulars and complains about something. Well, they might not say it was a complaint, just an observation, but it was a complaint. A minor one. It has something to do about being able to make something out of nothing. Sort of like me this morning, how to make a thread out of an empty head? But they (notice I am using the correct pronoun, not saying he or she), by what they said got me thinking. What I thought was: Not sure if that is the actual saying, if I remember correctly, I remember the saying going something like this: Umm, no, I don't think the saying I am thinking of goes that way either, maybe ONE of you good folks can remind me how the saying goes. Either way, when...
