A crewed mission to Mars may be more practical thanks to a new rocket concept developed by Fatima Ebrahimi, a physicist at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), that uses magnetic fields to generate thrust.
The CEO of an online payment company is the perfect leader for an emergency in outer space.
OK, hands up who thinks this is a really super dumb and risky idea but isn’t terribly surprised by the super dumb and risky things Musk continually blurts out? 🤷♂️
It’s hard to believe that it’s been 35 years since the disaster that claimed the lives of all seven Space Shuttle Challenger crew members.
I remember it well. Being sent home early without being told. Watching the TV news at home in silent shock with my parents and younger siblings, tears streaming down our faces.
President Reagan’s speech at Congress, made in the place of the traditional State of the Union address, ended with “they slipped the surly bonds of Earth…and touched the face of God.” Probably the finest and most decent thing he ever did (even my parents, who voted for Jimmy Carter and Walter Mondale and intensely disliked Reagan and everything he stood for, couldn’t help but be moved by his words that day).
Thoughtless jokes circulated our school the next week or two. (“What’s the last thing Christa MacAuliffe said to her husband? “You feed the dog; I’ll feed the fish.”)
There was a morbid fascination with the way in which the Challenger crew met their fate. My friends came up with all sorts of gruesome stories they claimed to have “heard,” mostly about body parts washing up on beaches around the Caribbean.
The fact is, we were traumatized. Kids do all sorts of insane things to hide their fears, insecurity, and general inability to answer the question what am I supposed to feel/do/say about this?
Challenger marked a turning point in the US space program. It set NASA back in many ways but also provided great insight into what needed to be fixed, what needed to be done to push forward our knowledge of space and the great beyond.
There is/was no going back. Humanity is a space-faring race and must continue to strive to reach beyond its grasp…”Or what’s a heaven for?”
It’s a small step. It applies only to companies that are working with NASA; it pertains only to U.S. lunar landing sites; it implements outdated and untested recommendations to protect historic lunar sites implemented by NASA in 2011. However, it offers significant breakthroughs. It is the first legislation from any nation to recognize an off-Earth site as having “outstanding universal value” to humanity, language taken from the unanimously ratified World Heritage Convention.
The author believes this shows that “nonpartisan” desire to journey to space and preserve human heritage.
Hmm.
Well, I do agree with the assessment that it’s only a matter of time before the Moon is occupied by multiple political entities (China, India, Russia, the US, ESA…) and probably even a few private enterprises as well. Will the private company-sponsored missions agree to abide by a US law?
Despite the impact, scientists believe that if anything survived the crash intact, it may well have been the tardigrades. The microscopic creatures were sandwiched between micron-thin sheets of nickel and suspended in epoxy, a resin-like preservative that acts like a jelly — potentially enough to cushion their landing.
Despite the lack of large marsquakes, the researchers were able to estimate how thick Mars’ crust is. They predict it has three layers—but possibly two—that are between 12.4 and 23 miles thick, reports Nature. Mars’ crust is considerably thinner than that of Earth, which can be up to 25 miles thick—and that’s surprising, reports Science.
…the team’s results suggest that, while the physical processes that drive the structure of the Universe and the structure of the human brain are extremely different, they can result in similar levels of complexity and self-organisation…
According to NASA estimates there are at least 100 billion stars in the Milky Way, of which about 4 billion are sunlike. If only 7 percent of those stars have habitable planets — a seriously conservative estimate — there could be as many as 300 million potentially habitable Earths out there in the whole Milky Way alone.
It takes a while to collect, sort through, analyze, write up, endure peer review, and publish data from scientific projects.
That’s why finally we’re seeing this, 11 years after Kepler was launched to scour the galaxy for exoplanets.
Now the real challenge will be figuring out how to get there…
It’s time to move on the next factor in the Drake equation for extraterrestrial civilizations: the fraction of these worlds on which life emerges. The search for even a single slime mold on some alien rock would revolutionize biology, and it is a worthy agenda for the next half-century as humans continue the climb out of ourselves and into the universe in the endless quest to end our cosmic loneliness.
