A change of 32 minutes in orbit β but only 4% of the total orbital period. To deflect an asteroid away from Earth, itβd better be done several years in advance. π
Ya know, Iβm pretty sure we need to figure out βthis whole food-air dealβ first (to quote comedian Bill Hicks).
βThe US space agency confirmed that there were currently no plans for a field or project office to explore the topic in any detail but that could change as we get closer to putting humans on Mars.β
They slice. They dice. They perform complicated microsurgery without the aid of doctorsβ¦
US researchers say a robot has successfully performed keyhole surgery on pigs all on its own β without the guiding hand of a human. Furthermore, they add, the robot surgeon produced βsignificantly betterβ results than humans.
Over the years, the SAA has been responsible for several spacecraft failures and even dictates when astronauts can and canβt perform spacewalks. As the space around Earth becomes filled with an increasing number of craft, what does the SAA mean for the future of spaceflight?
This post is from back in February 2021, but I just stumbled across it this morning and thought it was an interesting read.
Learn something new every day!
This part caught my eye…
Radiation is a colorless, tasteless, and odorless enemy…
…and I couldn’t help thinking…
Iocaine powder?!?
It’s okay. I’m immune π
Anyway, the article linked above is food for thought. Whenever electronic objects pass through the SAA, which is where the loops of the Van Allen Belt dip perilously close to the Earth, the electronics get a massive amount of radiation and go haywire.
Seriously expensive to shield stuff up there — and as more and more satellites (and people) go up, so does the risk.
Also the next one after that. And the one after that.
Itβs been a very tiring summer so far.
(For starters, we STILL donβt have enough Pfizer or Moderna vaccines, doses are get wasted left and right as the elderly randomly cancel reservations and the bureaucratic pinheads in charge refuse to give them to others, and several students at my school went out drinking and guess what happened…)
I havenβt even posted any science news lately.
But I promise that Iβll make up for it. Soon.
In the meantime, hereβs a neat little article about some wild theories of the universe, starting with the Brane Universe and the Big Splat.
Chinaβs plan calls for setting up a permanently occupied base and a fleet of interplanetary craft. Probably itβs a good idea to first see whether it can meet its goal of landing people on Mars in 2033.
Of course, China is βwilling to join hands with our counterparts and partners all over the world,β but itβs unlikely NASA, JAXA, ESA, and the UAE and other countries not named Russia will βcooperate.β
The next space race is here. Just wait until multinats actually decide asteroid mining is worth the risk and expense.
Itβs becoming increasingly common to see social media posts claiming that the mRNA COVID-19 vaccines, which include those made by Pfizer and Moderna, could alter a personβs DNA. Some posts even suggest that nano-machines are being injected into the body.
Yeah, Iβve seen some of these posts. Talked to a neighbor who was convinced Bill Gates was trying to inject us all with a chip to control our minds.
Is there any truth to these rumours? Could an mRNA vaccine be modifying your DNA?
No.
(Read the linked Cosmos article for more details!)
Actually, all you need to do is use logic and reasoning, apply some critical thinking, and demand lots of science-based evidence.
Itβs called the Baloney Detection Kit and was introduced in a Cornell University undergraduate course about critical thinking and the scientific method by astrophysicist Carl Sagan.
The link above to the kit also outlines some of the most important logical fallacies to avoid, with number 8 and 9 being the most difficult to explain and convince people about (because they involve education about basic statistics).
So will this convince anti-vaxxers who make outlandish claims online?
The inclusion of an ion propulsion system in a long-running, Earth-orbiting space station will give researchers a chance to test out the tech while astronauts are still close to home β and if it works as hoped, it could one day ferry explorers to Mars and even more distant destinations.
Another is what the price will be, since no doubt this neat new tech wonβt easily be shared among nation-states.
Just yesterday Chinese astronauts entered their new space station for the first time. They werenβt allowed into the ISS. Now they donβt need the ISS.
The old rivalries will follow humanity into space…but for how long will the rivalries remain…
