According to Space.com, the Falcon Heavy is the most powerful rocket to launch since NASA's Saturn V -- the iconic vessel that, with 7.5 million pounds of thrust, accomplished the definitive Apollo-era feat of putting astronauts on the moon. Elon Musk says that Falcon Heavy is "twice as powerful as any other booster operating today." As for the payload, it includes a Tesla Roadster electric car. "The Falcon Heavy will send the vehicle around the sun in an elliptical orbit that will extend farther than Mars' orbit," reports Space.com.
UPDATE: SpaceX has confirmed The Verge's reporting that the middle core of SpaceX's Heavy Rocket missed the drone ship where it was supposed to land. "The center core was only able to relight one of the three engines necessary to land, and so it hit the water at 300 miles per hour," reports The Verge. "Two engines on the drone ship were taken out when it crashed, SpaceX CEO Elon Musk said in a press call after the rocket launch. It's a small hiccup in an otherwise successful first flight."
For viewers in the Central and Mountain time zones, the moon will set either during the total eclipse or while the satellite is exiting the Earth's shadow. The moon enters the dark umbra at about 5:48 a.m. CST and will hit totality slightly before moonset, at 6:51 a.m. CST. The umbra will appear at 4:48 a.m. MST, and the moon will enter totality at 5:51 a.m. MST. Viewers in the Mountain time zone will also get the chance to see the middle of totality, when the moon is up to 100,000 times fainter than usual, at 6:29 a.m. The eclipse will end slightly before moonset, at 7:07 a.m. MST. Viewers in Alaska and Hawaii will get a full dose of totality, too, but they'll have to be very early birds or night owls. Totality begins at 3:51 a.m. AKST and ends at 5:05 a.m. AKST. Totality hits at 2:51 a.m. HST and will be over by 4:05 a.m. HST.
Just 60 seconds before lift-off yesterday, a "rogue ship" entered their launch-range area, prompting them to postpone the launch until today. GeekWire reports: This mission was nicknamed "Still Testing," but unlike the first mission, the objective was not merely to test Rocket Lab's hardware. The rocket had the additional task of putting three nanosatellites in orbit: an Earth-imaging Dove satellite for Planet, and two Lemur-2 satellites that the Spire space venture would use for tracking ships and monitoring weather... The price tag for a mission is as low as $5 million, thanks to streamlined hardware production techniques. The Electron makes use of carbon composite materials for its rocket core, and 3-D printing techniques for its Rutherford rocket engines.
90 minutes ago Spire tweeted that they'd experienced a "good clean deployment" of their satellites, adding that they were already receiving images and calling it "a huge win" for commercial space, small satellites, the Electron rocket, and New Zealand.
UPDATE: Long-time Slashdot reader Hairy1 shares Rocket Lab's video of their launch.
"It isn't clear how French maid outfits symbolize cryptocurrency or blockchain technology," notes Quartz, "but they're popular costumes in Japan's anime and cosplay circles."
Despite the Moon's dry and dusty appearance, scientists think it contains a lot of water trapped as frozen ice. What these new observations carried out by NASA's Lunar Reconnaissance Orbiter (LRO) show is that it might be much more accessible than we thought... Scientists have long been thinking about how to extract the ice reserves we think are up there -- solar power was originally out of the question, as it's the freezing shadowed areas of the Moon that have preserved the ice in the first place. Not only would natural skylights like these provide easier access to the underground ice, it would also mean solar power would be back on the table as an idea.
On one space shuttle flight, two of the ship's three auxiliary power units actually caught on fire, and exploded just minutes after touchdown. But Young always kept his cool. In 2010 Slashdot remembered the first manned Gemini mission in 1965. When it reached orbit, Young surprised his fellow astronaut Gus Grissom by pulling a fresh corned beef sandwich out of his pocket.
An anonymous Slashdot reader writes:
Andrew Chaikin, author of "A Man on the Moon: The Voyages of the Apollo Astronauts", remembers that Young "used to talk about how if we stay on this planet for too long, something's going to get us, whether it was a super volcano or whatever. He really was a true believer." NASA Administrator Robert Lightfoot added that Young's career "spanned three generations of spaceflight; we will stand on his shoulders as we look toward the next human frontier."
In 2012 -- when he was in his 80s -- Young published a memoir titled Forever Young: A Life of Adventure in Air and Space. "My life has been long, and it has been interesting. It's also been a lot of fun, and a lot of hard, challenging work. If I could do it over, I would do it over the very same way.
The new equipment includes sensors to monitor for organics and measure environmental factors like the presence of dissolved oxygen and levels of acidity, all to see if Europa could (in theory) support life in its subterranean seas... The subsea drone is also smarter than its prototype predecessor, and that high-IQ autonomy would be needed on Europa. The probe must not only operate 400 million miles from Earth but also navigate all by itself under alien ice.
[...] "Despite popular conceptions," the authors point out, "[conspiratorial thinking] is not the sole province of the proverbial nut-job." When mixed in with the sort of motivated reasoning that ideology can, well, motivate, crazed ideas can become relatively mainstream. Witness the number of polls that indicated the majority of Republicans thought Obama wasn't born in the U.S., even after he shared his birth certificate. While something that induces a healthy skepticism of information sources might be expected to help with this, it's certainly not guaranteed, as motivated reasoning has been shown to be capable of overriding education and knowledge on relevant topics.
[...] As a whole, the expected connection held up: "for both conservatives and liberals, more knowledge of the news media system related to decreased endorsement of liberal conspiracies." And, conversely, the people who did agree with conspiracy theories tended to know very little about how the news media operated.
