Nudge it, nuke it, tug it with a gravity tractor, or slow it down with some concentrated sunlight. Make my day, planet-killers.
Those are your choices if a planet-killing comet or asteroid is en route to rather imminently collide with Planet Earth. Asteroid PZ39 shot by the Earth from a distance of more than 3.58 million miles (5.77 million kilometres) earlier this month. It flew towards us at speeds of more than 35,500 mph (57,240 km/h), approaching just after 11 a.m. GMT two weeks ago on Saturday, Feb 15.
A near-miss? “A little over 9x the distance of the earth to the moon,” Ron Graham helpfully explained. “A near miss is, in fact, an impact,” Kevin Hopton added
Both asteroids and comets are bad to have coming toward you, but comets are worse apparently simply because they can be travelling up to three times faster than Near-Earth asteroids (NEAs) relative to Earth at the time of impact. The energy released by a cosmic collision increases as the square of the incoming object’s speed, so a comet could pack nine times more destructive power than an asteroid of the same mass. But both are considered to be a potentially hazardous object (PHO).
“It would be a much bigger explosion, a much bigger crater, much more damage,” (https://www.space.com/26264-asteroids-comets-earth-impact-risks.html) impact expert Mark Boslough, of Sandia National Laboratories in New Mexico, said in June 2104.
If Boslough says it is so, that’s good enough for me. After all he is the author of this now famous account, dated Dec. 25, 1998, which I wrote approvingly of in a post on Nov. 9, 2014 headlined “‘Edward Baker:’ Thompson, Manitoba’s microwaved telephone company night watchman 1998 urban legend owes its fame to real-life American scientist and a Denver newsman” (https://soundingsjohnbarker.wordpress.com/2014/11/09/edward-baker-thompson-manitoba-s-microwaved-telephone-company-night-watchman-1998-urban-legend-owes-its-fame-to-real-life-american-scientist-and-a-denver-newsman/)
Wrote Boslough back in 1998:
“Telephone relay company night watchman Edward Baker, 31, was killed early Christmas morning by excessive microwave radiation exposure. He was apparently attempting to keep warm next to a telecommunications feedhorn.
“Baker had been suspended on a safety violation once last year, according to Northern Manitoba Signal Relay spokesperson Tanya Cooke. She noted that Baker’s earlier infraction was for defeating a safety shutoff switch and entering a restricted maintenance catwalk in order to stand in front of the microwave dish. He had told coworkers that it was the only way he could stay warm during his twelve-hour shift at the station, where winter temperatures often dip to forty below zero.
“Microwaves can heat water molecules within human tissue in the same way that they heat food in microwave ovens. For his Christmas shift, Baker reportedly brought a twelve pack of beer and a plastic lawn chair, which he positioned directly in line with the strongest microwave beam. Baker had not been told about a tenfold boost in microwave power planned that night to handle the anticipated increase in holiday long-distance calling traffic.
“Baker’s body was discovered by the daytime watchman, John Burns, who was greeted by an odor he mistook for a Christmas roast he thought Baker must have prepared as a surprise. Burns also reported to NMSR company officials that Baker’s unfinished beers had exploded.”
The clues, of course, to the fabricated nature of the story are contained in the names of the participants: the victim, “Baker”; his discoverer, “Burns”; and the spokeswoman, “Cooke.”
Boslough attached his microwaved worker offering to a then-current list of Darwin Award stories for 1998, declared his entry to be that year’s winner, sent it out to a few friends and sat back and watched the inevitable unfold, as veteran Denver Post editor and columnist Dick Kreck was taken in by the hoax, publishing it as the authentic 1998 Darwin Award winner. It seems, at some level, we all want to believe.
Certainly, Kreck, who retired from the paper in June 2007, was no rookie. Born in San Francisco in 1941, Kreck grew up in Glendale, California. After earning a bachelor’s degree in journalism from San Francisco State College, he worked as a reporter and copy editor at the San Francisco Examiner and the Los Angeles Times. He joined The Denver Post in 1968 and held various jobs, writing a city column for 18 years and covering television and radio. His books include Colorado’s Scenic Railroads; Denver in Flames; Murder at the Brown Palace; Anton Woode: The Boy Murderer ; and Smaldone: The Untold Story of an American Crime Family.
Boslough wrote to Kreck in 1999:
“Dear Mr. Kreck:
“Thank you so much for reprinting my Darwin Award hoax in the Denver Post.
“Like you, I am a skeptic and have always very suspicious of these stories. However, I am also a scientist so I decided to do a little experiment. I made up the most outrageous and twisted death-by-stupidity tale I could imagine. I made sure that all the characters in the story had names (Mr. Baker, Mr. Burns, Ms. Cooke) that would give my joke away to any wary reader. I set the story in a location that allowed the company “Northern Manitoba Signal Relay” to have the same acronym as New Mexicans for Science and Reason, our local version of Boulder-based Rocky Mountain Skeptics.
“I took a list of Darwin Awards that somebody sent me and attached my own creation, which I also declared to be this year’s winner. I turned it loose by e-mailing it to a few out-of-state friends on New Year’s Day. Seeing it this week in the Post is a bit like getting a response to a note in a bottle eight months after throwing it into the ocean. It is also a good lesson in why we should all be skeptical of what we see on the Internet … not to mention what we read in the newspaper!
“By the way, NMSR president Dave Thomas – a recent guest speaker at Rocky Mountain Skeptics – is the only person who discovered the hoax and correctly attributed it to me. He had searched for “NMSR” under Deja News and recognized my brand of humor when his search turned up my story.
“Best regards,
“Mark Boslough”
There are, of course, lot of people besides Boslough whose job it is to think about such things on both a theoretical and practical basis. I’m not one of them.
Rafi Letzter, a staff writer for New York-based Live Science wrote earlier this month:
“If a giant object looks like it’s going to slam into Earth, humanity has a few options: Hammer it with a spacecraft hard enough to knock it off course, blast it with nuclear weapons, tug on it with a gravity tractor, or even slow it down using concentrated sunlight ” (https://www.livescience.com/how-to-stop-asteroid-from-hitting-earth.html)
Massachusetts Institute of Technology (MIT) researchers have come up with an 18-page guide titled “Optimization and decision-making framework for multi-staged asteroid deflection campaigns under epistemic uncertainties” (https://www.sciencedirect.com/science/article/abs/pii/S0094576519313700?via%3Dihub), also published earlier this month, in the journal Acta Astronautica, to help, in Letzter’s words, “future asteroid deflectors.”
For those taking the longish catastrophic view, rather than the shortish catastrophic view, here’s something to consider:
“If an approaching asteroid were detected early enough,” the National Aeronautics and Space Administration (NASA) says, “it could be possible to divert its path using the gravity of a spacecraft (https://www.nasa.gov/content/asteroid-grand-challenge/mitigate/gravity-tractor). “Instead of sending an impactor to ram into an approaching object, a gravity tractor device would fly alongside the asteroid for a long period of time (years to decades) and slowly pull it out of Earth’s path.
Gravity tractors would be most likely to work on any shape or composition of approaching asteroid, even if it were just a pile of rubble. However, gravity tractors might not be effective for the largest asteroids of over 500 meters in diameter which might be the greatest threat to Earth. Gravity tractors offer the greatest control and could perhaps even divert an approaching asteroid to other locations in space where people could theoretically use them for research or commercial purposes. However, these techniques have never been tried and would require decades for building, launching, and carrying out a mitigation mission.”
On March 26, 1997, police in Rancho Santa Fe, California discovered the bodies of 39 members of Heaven’s Gate, an American UFO religious millenarian celibate cult based in San Diego, founded in 1974 and led by Marshall Herff Applewhite and Bonnie Lu Trousdale Nettles. The 39 cult members who died almost 23 years ago took phenobarbital mixed with apple sauce and washed it all down with vodka. Additionally, they secured plastic bags around their heads after ingesting the mix to induce asphyxiation. Authorities found the dead lying neatly in their own bunk beds, faces and torsos covered by a square purple cloth. Each member carried a five-dollar bill and three quarters in their pockets: the five dollar bill was to cover vagrancy fines while members were out on jobs, while the quarters were to make phone calls. All 39 were dressed in identical black shirts and sweat pants, brand new black-and-white Nike Decades athletic shoes, and armband patches reading “Heaven’s Gate Away Team.” Among the dead was Thomas Nichols, brother of actress Nichelle Nichols, best known for her role as Uhura in the original Star Trek television series.
They had participated in the mass suicide in order to reach what they believed was an extraterrestrial spacecraft following Comet Hale-Bopp, as it approached Earth. They believed an alien spaceship hiding in the tail of a speeding comet was coming to collect their souls.
Earth-threatening asteroids might well be movie or book genres of their own. On the movie side, there are such classics as American science fiction disaster film classic Armageddon from 1998, depicting Bruce Willis et al. saving the Earth. The movie has Harry Stamper (Willis) and his oil rig crew (who are mostly losers who have done time in jail) being hired by NASA as astronauts. Their goal is to drill into an asteroid the size of Texas and deploy a bomb to break it into pieces, before the asteroid hits the Earth.
One of my favourite cover versions of the many that have been done over the years of the song Leaving on a Jet Plane is by Winnipeg’s Chantal Kreviazuk from Armageddon, produced by Jerry Bruckheimer, and featuring a heartfelt, if somewhat off-key, opening rendition to the song by Ben Affleck from the movie, leading to the delightful mission control quip: “So, Truman, this is who you found to save the planet.” (https://www.youtube.com/watch?v=bbt2G71uT1M&feature=share&fbclid=IwAR1KgfVHJxTwyayZ-pLStZ2H0RSeinmKhRqhPPGxR3L2HcIFj6j8vXbdj5s).
On the book side, I’m partial to Lucifer’s Hammer by Jerry Pournrelle and Larry Niven. I read the novel an early paperback edition shortly after it was published in 1977, while I was a student at Trent University on a late fall three-hour one-way trip on and old Voyageur Colonial Bus down Highway 7 and back from Peterborough to Ottawa and back on weekend trip. A great page-tuner for a cold late autumn bus ride.
This is also around the time Pournelle, an American polymath: scientist in the area of operations research and human factors research, as well as noted science fiction writer, essayist, journalist, and one of the first bloggers (https://io9.gizmodo.com/rip-jerry-pournelle-a-tireless-ambassador-for-the-futu-1803143871) became perhaps the first writer from any genre to sit and compose at a typewriter connected to a television screen, forerunner of today’s desktop computer, to compose, edit, and revise there, and then to send copy to his publisher. Jerry Pournelle, early adopter, died in September 2017 at the age of 84.
