A technical question about the lack of a tail? "Tails are lame." A question about why the number of landing legs was increased from 3 to 4? "Because 4." After one Redditor observed "This is one bizarre AMA so far," Musk replied "Just wait..." While Musk ultimately did follow up some of the trolling with some actual responses, the overall event could be best described as "surreal".
To be fair, Musk provided some serious answers. (And his final comment ended with "Great questions nk!!") But one Redditor suggested Musk's stranger answers were like a threat, along the lines of "Just wait. It will get way more bizarre than that. Let me finish my whiskey."
Musk replied, "How did you know? I am actually drinking whiskey right now. Really."
The article embeds both videos -- and also links to the music videos they're parodying. And it includes links to SUSE's two previous annual music video parodies -- Uptime Funk (based on Bruno Mars' blockbuster hit "Uptown Funk"), and Can't Stop the SUSE, a parody of Justin Timberlake's "Can't Stop the Feeling".
Our space agencies won't be able to push out farther into space, to a destination like Mars, until we can learn more about how to strengthen the weakest links in the chain that make space flight possible: the human body and mind... [V]ery little is known about what occurs after month six. The symptoms may get precipitously worse in the ninth month, for instance, or they may level off. We don't know, and there is only one way to find out... On my previous flight to the space station, a mission of 159 days, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained and shrank the walls of my heart. More troubling, I experienced problems with my vision, as many other astronauts had. I had been exposed to more than 30 times the radiation of a person on Earth, equivalent to about 10 chest X-rays every day. This exposure would increase my risk of a fatal cancer for the rest of my life.
Kelly says the Space Station crew performed more than 400 experiments, though about 25% of his time went to tracking his own health. "If we could learn how to counteract the devastating impact of bone loss in microgravity, the solutions could well be applied to osteoporosis and other bone diseases. If we could learn how to keep our hearts healthy in space, that knowledge could be useful on Earth." Kelly says he felt better a few months after returning to earth, adding "It's gratifying to see how curious people are about my mission, how much children instinctively feel the excitement and wonder of space flight, and how many people think, as I do, that Mars is the next step... I know now that if we decide to do it, we can."
Today, with NASA once again considering the challenges of sending astronauts to Mars, the nuclear option is back on the table as part of the agency's Game Changing Development program. Under this, NASA has awarded BMXT, which supplies nuclear fuel to the U.S. Navy, a $18.8-million contract running through September 30, 2019 to look into the possibility of developing a new engine using a new type of fuel. Unlike previous designs using highly enriched uranium, BMXT will study the use of Low-Enriched Uranium (LEU), which has less than 20 percent of fissile uranium 235. This will provide a number of advantages. Not only is it safer than the highly enriched fuel, but the security arrangements are less burdensome, and the handling regulations are the same as those of a university research reactor. If NASA determines next month that the LEU engine is feasible, the project will conduct testing and refine the manufacturing process of the Cermet fuel elements over the course of a year, with testing of the full-length Cermet fuel rods to be conducted at Marshall.
Slashdot reader Big Hairy Ian adds: "At the very least it looks much more feasible than Project Orion."
"Yeah, that was a tough decision," Musk acknowledged Wednesday with a sigh. "The reason we decided not to pursue that heavily is that it would have taken a tremendous amount of effort to qualify that for safety for crew transport," Musk explained Wednesday. "There was a time when I thought the Dragon approach to landing on Mars, where you've got a base heat shield and side mounted thrusters, would be the right way to land on Mars. But now I'm pretty confident that is not the right way." Musk added that his company has come up with a "far better" approach to landing on Mars that will be incorporated into the next iteration of the company's proposed Mars transportation hardware.
Several governors asked Musk how to regulate the emerging AI industry, to which he suggested learning as much as possible about artificial intelligence. Musk also warned that society won't know how to react "until people see robots going down the street killing people... I think by the time we are reactive in AI regulation, it's too late."
Dubbed "Chubby 5" for its huge size -- 5 meters in diameter and 57 meters tall -- the LM-5 rocket is designed to carry up to 25 tons of payload into low orbit, more than doubling the country's previous lift capability... The launch failure means further delay for a series of planned Chinese space endeavors -- including its robotic and eventual human lunar programs -- according to Joan Johnson-Freese, a professor at the US Naval War College and an expert on China's space program... China has announced plans to land a robotic probe on the dark side of the moon later this year and to reach Mars around 2020. All such future missions will depend on the LM-5 and space officials told reporters Sunday that the latest launch would help perfect the rocket design, including enabling it to send a space station into orbit "in a year or two."
This morning Elon Musk tweeted his condolences, adding "I know how painful that is to the people who designed & built it."
The object would be different from -- and much closer than -- the so-called Planet Nine, a planet whose existence has yet to be confirmed... "The most likely explanation for our results is that there is some unseen mass," says Kat Volk, a postdoctoral fellow at the University of Arizona's Lunar and Planetary Laboratory and lead author of the study in the Astronomical Journal. "According to our calculations, something as massive as Mars would be needed to cause the warp that we measured."
