Back in the 1990's we lived deep in the Rockies, in Wyoming. I remember going out at night to view comet Hale-Bopp, and with no light pollution, the tail stretched nearly a third of the way across the sky and was greenish in color.

[@SeauxNOLALady]

One of the main scientists on the Rosetta mission was so excited when they thought the lander successfully landed and was stable on the surface of the comet that she was jumping up and down and screaming in delight. Then they realized the lander actually bounced off the surface and had tumbled and was wedged in a crevice and incorrectly positioned to do the intended experiments. She must have been devastated, but they only had a day or two to complete as much work before the power supply dwindled to nothing because the solar panels were shaded from sunlight. Years later she told her experience in a documentary video. The team was under extreme pressure to get the most out of what little time the craft had left so she didn’t have time to focus on the disappointing failure to land properly. The data gathered from the limited time was still a huge contribution to the field.

I was in college when Stardust-NExt met up with Temple 1. The complexity of the necessary calculations needed to ensure that the spacecraft rendezvoused at the exact time to image the crater left by Deep Impact collision are difficult to wrap your head around! I have a science degree and am good at math, but I can’t even think how intricate and precise those calculations must have been, so when the mission was a success, I was extraordinarily impressed. The DART mission was the next leap forward for the study of near earth objects and the ability to detect and divert potential collisions with our home planet. The science done by the exceptionally brilliant scientists in the space agencies is evolving exponentially every mission.

Shoemaker Levy 9 terrified me. If it had missed Jupiter it would have been hurled into the inner solar system right in our neighborhood. Im not an expert but Jupiter showed its worth during that encounter. However, at the same time, if the comet had missed, Jupiters gravitational influence may have hurled the many fragments helter skelter into the inner solar system, actually increasing our odds of getting hit by at least one of the fragments maybe more. Jupiter is both a blessing and a nightmare at the same time.

Among my most highly recommended literary works is "Lucifer's Hammer," a collaborative effort by Larry Niven and Jerry Pournel. This epic novel explores the catastrophic consequences of a collision between Earth and massive cometary fragments, resulting in the near-annihilation of human civilization. Despite its age, the book remains a seminal work that introduced me to the concept of such an impact and its potential ramifications.

[@Safetytrousers]

An asteroid that would have caused problems had it been on an Earth trajectory was successfully perturbed by an impact such that it would have missed, so we're safe from anything like that.

_"the middle part is getting electrically etched"_ Not according to anyone familiar with physics. Or with the evidence from comets.

[@theklaus7436]

What physics, calculations and science is capable of doing is so amazing I get goosebumps. I love science especially science about the universe. And knowing what we can do stands in total opposite of how we behave with our wars and conflicts . The day we unite- the sky is the limit. Science in general is the most beautiful thing we as humans have achieved. I need to see more of this when I feel blue over the atrocity happening here on earth. 🎸😊🇩🇰

Fantastic documentary, thank you!

I hate when the analogy of “with the force of ‘X’ atomic bombs” is used. Atomic weapons vary in scale, with some being hundreds of times bigger than what was dropped in Hiroshima. It’s like saying “the comet weighed as much as seven boats” lol

[@paganphil100]

@JuiceBlack: When they measure some sort of force and compare it to A-bombs they usually mean the Hiroshima bomb.

Where is the ice? Where is the snow?

[@davejones7632]

Thousands of tonnes of ice excavated from the Tempel 1 impact. A shed load around Hartley 2 when it was visited in 2010. Plenty of ice.

[@raycar1165]

@@davejones7632yeah because ice and snow always lights up when contacted by copper… 🧐

[@davejones7632]

@@raycar1165 Correct. Ice is very reflective. That is why they could detect it spectroscopically in absorption after the impact in the ejected material. Didn't the EU story tellers tell you about that? It has been in the literature for ~ 20 years. Didn't you bother reading it? Did you just take the word of unqualified mythologists who lied to you? Do better. They saw thousands of tonnes of ice, shed loads of dust, and not a single signal to indicate any electrical woo, in any wavelength you care to name. You were conned. Be less gullible.

Awesome super cut! I should mention that Armageddon was the film about sending a team of oil drillers to blow up an asteroid on a collision course with earth. Deep Impact was about a comet actually hitting earth. Both films are dreadful 😂

And then we have "Don't Look Up" which probably is the more realistic approach ^

The ingenuity of these scientists is astounding. The fact that Voyager is still out there transmitting is an insane scientific achievement.

Experts - "Trust science, we know our stuff" Skeptics - "I think you need to do more testings" Experts - "Shut-up anti-science" (censors skeptics) Model proven wrong Experts - "welp, see this is how science works, trust science"

[@clauslangenbroek9897]

Because science is all about testing. You don't say to a bus driver "You should do more bus driving," except for implication of criticism. On the other hand, testing is all about uncertainties (normally, scientists are very upfront about this, because that's what they do. In their papers, mind you, not in comment sections.) I think they are right to shut them up.

[@NicholasLatipi]

as long I am not compelled to participate in their testings and experiment as lab rats and demonized if I resist I don't care how they do their "science"

​@@clauslangenbroek9897Appeal to authority is a logical fallacy for a reason. Hubris is one of humanity's worse traits.

[@bleekcer]

I don't know whose fault it is, scientists or communicators, but it certainly is infuriating, how models and hypothesis are presented as facts so many times, just because they are the best guesses at the current time. Half of what I learned as a kid, and were presented as facts already proved to be wrong today.
