NASA's InSight Successfully Lands on Mars (theverge.com)
NASA's latest Mars lander, InSight, successfully touched down on the surface of the Red Planet moments ago, surviving an intense plunge through the Martian atmosphere. From a report: It marks the eighth picture-perfect landing on Mars for NASA, adding to the space agency's impressive track record of putting spacecraft on the planet. And now, InSight's two-year mission has begun, one that entails listening for Marsquakes to learn about the world's interior. After six and a half months of traveling through space, InSight hit the top of Mars' atmosphere a little before 3PM ET. It then made a daring descent to the surface, performing a complex multi-step routine that slowed the lander from more than 12,000 miles per hour to just 5 miles per hour before it hit the ground. To get to the surface safely, InSight had to autonomously deploy a supersonic parachute, gather radar measurements, and ignite its thrusters all at the right time. Altogether, the landing took just under seven minutes to complete, prompting the nickname "seven minutes of terror." "InSight's view is a flat, smooth expanse called Elysium Planitia, but its workspace is below the surface, where it will study Mars' deep interior," Nasa posted Monday, sharing the first photo after the landing.
Hijacking that inane comment to ask another, likely inane question.
Would it be unreasonable to assume that they have been placing sensors on these spacecraft to register the various radiation levels experienced during the trip to Mars. This seems like it would be invaluable empirical data of what those anxious to get there in person will face on the trip.

The term is in the quote from The Verge. You can complain to them that their article is using terminology that you don't like, but commenting about it here accomplishes nothing.
Picture shows pimples on a butthole
But it isnâ(TM)t on earth, therefore mars quakes
We call earthquakes earthquakes.
Yes, because they occur on the Earth.
For some reason, earthquakes on Mars are now called Marsquakes?
Well, they certainly aren't earthquakes. Perhaps they should simply be called "quakes". But earthquake is definitely not correct.
If you have to make up a word and make it a proper noun for a really fundamental effect on a science and technology news website, something is seriously wrong.
I'd say marsquake is pretty accurate. Certainly more so than earthquake. "Earthquake" is simply two words put together to describe the ground on the earth shaking. If it occurs on Mars, then to say the Earth is quaking would be very inaccurate.
New words are made up all of the time and the meaning of some words change over time as well. If you don't like it, speak Latin. It's a dead language it isn't supposed to evolve.
Well that begs the question, is Mars' dirt called "mars" the same way Earth's dirt is called "earth"? And then also who's going to go back and adapt all the works of Literature for Martian perspective also?
And most importantly why the fuck are we wasting our time asking dumb questions like this instead of something interesting?
I'd say this has to be one of the most important missions in years in terms of space research.
This will open the doors to future Mars missions by showing the internal geometry of the planet, potentially leading to liquid water, caves for future colonies and underground chemistry.
Equally the Risk Assessment of space impacts to know for sure just how frequent they are.
But as a bonus, also a test of deep-launch cubesats, which can be used to help massively improve the Deep Space Network as well as do experiments around lesser bodies like asteroids since they are so disposable with their cheap(er) development prices.
I can only hope it doesn't go awry. It'll be crushing. Probably worse so than the Beagle2 failure.
well let's follow this to the logical conclusion: "Uranusquake" ... that won't be abused at all.
But really, there's geological phenomena that are not going to be unique to earth; coming up bespoke names for them on each planet/world we come into contact with is silly.
A mars quake makes all the mars rats come out of the mars holes and ask for spare mars change
They are called earthquakes (little e) because earth = ground/land, not because they occur on Earth. Mars would still have earthquakes, not Marsquakes.
If you're going to pretend someone said something, quote or paraphrase accurately or STFU. He said ongoing buzz-talk of colonizing it anytime soon is pointless for several reasons - Your dishonest preposition nonwithstanding.
There's nothing on Mars that requires human beings in the flesh to discover. We're landing robots because it makes sense. Bill Nye isn't against that, he's against morons pushing ridiculous bullshit like you just tried.

John McAfee 'It was like that time I hired that Bangkok prostitute; to do my taxes, while I fucked my accountant'
Right. It's not like we've been measuring and talking about moonquakes since the 1960's... Oh wait, we have! Surprise, people use words in a way you personally don't like! English is a living language, the horror!
I am glad the NASA commentators were not constantly talking during the 7 minute landing sequence. This is how you build suspense. By not talking and letting the time flow and the suspense build. Hollywood could learn a lot by watching this NASA landing event.
Well done.
Earthquake is not a proper noun, therefore it is not only applicable to Earth. That would be like calling an earthworm on mars a marsworm.
Yes, because they occur on the Earth.
No, the word earthquake goes back to the 14th century, a century before the planet was first called Earth. It means ground, not the planet.
Which is rather obvious, because the entire Earth does not quake.
Actually no, (not to defend nutter APK but...) THIS^ problem is c6gummer who is impersonating APK here for a long time now. C6gummer is one of the swastika spam-children ruining American society. #ROPE
well let's follow this to the logical conclusion: "Uranusquake" ... that won't be abused at all.
I don't think we need to worry about that on any of the gas giants.
Like I said in my previous post, they should simply call them quakes on any other planet/moon and be done with it.
That's a hell of a thing to say! It's a desolate frozen rock!
“He’s not deformed, he’s just drunk!”

No thanks
That is a huge accomplishment to be able to do that. Good job by NASA!
Easy solution: create an account.
I'd call a worm on Mars a marsworm, it if was a worm native to Mars.
If it was an earthworm that someone sent to Mars though, it would still be an earthworm. Probably a dead one.
Cordero's not over an hour away so I takes a drive up the bypass farther than any fool would care to and I ain't seen squat for no lander. Liars!
NASA seems to have got Mars landings down nearly pat. Although the article didn't exactly say, it seemed like this descent was similar to other recent landers, will have to look for exact details...
Also really cool to have two CubeSats orbiting Mars now as well.
Still not out of the woods yet, the craft has to deploy solar panels - hope that works out! Great work NASA!

This probe didn't have sensors, but that data is pretty well known. The radiation environment in deep space was measured throughout the Apollo years through Pioneers 6/7/8 were placed into Solar orbit to measure the radiation environment. Additionally, most of the deep space probes (Voyager 1/2, Pioneer 10/11, all had particle/plasma detectors on them to detect the radiation environment. So yes, there's pretty darned good data on the radiation environment of deep space.
And, more specifically, the Curiosity rover had a radiation detector specifically designed to characterize the surface radiation levels: https://mars.nasa.gov/msl/miss...
which is complementary to the Mars Odyssey orbiter, which characterized the radiation above the atmosphere: https://mars.nasa.gov/odyssey/...

Earlier this afternoon the The Council of Elders announced in triumph that they have once again detected and deflected the efforts of the blue world to land upon our soil.
K'Nord, Speaker for the Council of Elders, told reporters in a lengthy and jovial press conference
Shortly thereafter, a junior analyst in the room was overheard suggesting that the vessel was in fact designed to be stationary, and that it furthermore contained a drilling device designed to penetrate deeply into the planetary soil. Quickly reiterating the victory at hand, K'nord then had the analyst's gelsacs extracted and pulpified, to be used as a cleaning solution for the Council members' glasses.
Didn't THE scientific mind of our times, Bill Nye, just last week pontificate that Mars exploration is pointless?
No, he didn't.
He did pontificate against human colonization and terraforming of Mars. (He didn't exactly say he was "against" it: was he said was that he thought it would never happen). But he said he was in favor of human exploration of Mars.

I don't bet against NASA anymore. After Curiosity used the "Sky Crane" to land on Mars I had to sing the Star-Spangled Banner naked on the roof of an office building in Ohio. Which meant that it was just another day in Ohio, but I was certain that that thing was going to be a smoking hole in Mars...
I am not interested in articles about life extension advancements.
Either they're caught in a shitstorm or they were attacked by a swarm of Martian bees.

Or actually naked?
It's the business class that is bankrupting America. Smart people are normally in the Middle class.
It isn't sudden. The terms "moonquake" and "marsquake" have been in use for several decades, including in scientific publications (e.g. this 1972 paper about moonquakes).
Congratulations, NASA, for successfully landing an $850 million USD cordless drill on another planet.
> > We call earthquakes earthquakes.
> Yes, because they occur on the Earth.
That's inaccurate. Earth, meaning dirt. Not earth meaning the planet.
Oh well! Slightly less cool then, but still an interesting idea.
It looks like they won't last longer than a few weeks, after that just orbiting as you said in an elliptical orbit - it would be nice if they had planned that to just exit the solar system or hit the sun, you can't start worrying about deep space debris too early!
They do have tiny engines it appears, but just enough for small adjustments. Interesting the reason they have two was just for redundancy but it seemed both worked.

Uh yeah, actually it does. How do you think we detect distant earthquakes with local sensors? How do you think Teller was able to tell that Ivy Mike was successful by using a seismometer in California? When the ground moves, the earth moves. You may not be able to feel is with your feet, but the shockwaves do travel the globe.

From the desk of his Imperiousness Qwerrfygrum:
"Once again, the watery inhabitants of the Third Planet have assaulted our Beloved Homeland.
25 Years ago, their attacks began, first with a suicidal crash, second with a landing that our Illustrious General Grogooglebarg (may his essences swim forever) disabled only moments after touchdown.
We have managed over these years to maintain a strong success rate, with more than half their attacks being diverted, disabled, or destroyed before tainting our Red Fundament.
Recently, some of their attack craft have landed and continued to roam. Those responsible for disabling these craft have been sequentially sacked until we've found the right Tentacle for the job! I believe I can say with confidence they have all been terminated finally.
Unfortunately, however, the grim news of another lander cannot be refuted.
The only way this could possibly get worse would be if this new attack craft actually drilled into Mother Mars, violating her sacred surface.

Take a look at who pays taxes and who receives tax money.
It's the rich and the middle class that pay and it's the lower classes who take.
Now take a look at how much needs to be cut from the budget and compare that to the what the budget is being spent on.
The only way to balance the budget and bring spending under control is to cut military spending and entitlement spending.
We can argue about how much to cut from which, but both must be reduced if bankruptcy is to be avoided.
And that won't happen until and unless the greedy masses that feed at the government trough (military/industrial complex and welfare recipients) are silenced. The mob must be prevented from stampeding otherwise they'll capsize the boat we're all riding in.

That sky-crane was crazy. It's hard to believe there were not simpler alternatives. It was done in part to test technology to be used for more accurate landings so that rovers don't have to waste time and wear getting to the best targets. In the future, a hover-craft may take the rover/probe to the prime spot and then lower it down via a sky-crane.
The traditional (Viking-esque) way has an error radius of roughly 20 miles.
For InSight they opted for the old-fashioned way because accuracy wasn't an issue for this mission, being it's for general exploration of the sub-surface.
Table-ized A.I.
Seriously... it really does. It rings like a bell as the P and S waves travel through and around the planet. This is actually the principle that allows InSight to work. The fact that a quake is detectable anywhere because it creates vibrations of the entire planet. The Sendai, Japan quake actually altered the axis of mass of the Earth by about 6.5 inches.
InSight will watch for P, S, and surface waves (a total of 5 types in all) and use that information to figure out the original position of the quake and how the waves change from their origin will give clues as to the internal structure of the planet. Just as on Earth, earthquake waves are refracted and reflected and speed up/slow down as they travel through different mediums. It is a brilliant bit of science they are about to start in on.
Yeah, like Musk could do anything like this. Give me a break. He can dig tunnels and put rockets into LEO.
more interesting to land on, other than Mars. Some of the moons of Jupiter, for example. I guess that's just too hard right now...
The problem with reaching the Jovian moons is that they lack atmosphere for aero-braking, which means you need to send not just a small probe, but a big rocket to stop it. A much better candidate for landing is Titan, the big moon of Saturn. Such a mission has already been done, launched 21 years ago, and landed in 2005:
https://en.wikipedia.org/wiki/...
How soon we forget. And let's not also forget the Russian landings on Venus has some success.
In the Andromeda Strain, Crichton begins by explaining the certainty of widespread life across our solar system as proved by microscopic proof of life in asteroids that have hit the Earth.
The first life searching probe that landed on mars and used chemical means proved conclusively that Mars has microscopic life.
But Earth is ruled by or-ganised re-ligion. The power of the major religions, especially in the USA and Rus-sia cannot be overstated. These all powerful bodies have not decided what the impact of widespread acceptance of extra-terrestrial life would have on their control ma-trix, so they take the coward's way, and supress all scientific discoveries in the 'wrong' direction.
A ton of church paid propaganda pooh-poohed the asteroid and chemical analysis evidence. Loads of scientists are also members of churches- and many al-pha scientists think the church is essential for pacifying and controlling the "lesser"- so do its bidding even when they know the message is a lie, "for the greater good".
Today this means NO MICROSCOPES ON MARS. Dribblers, like the common visitor here, do not know the impact Hooke's invention had on biological sciences at the time. While the church easily has its paid liars characterise the fossils of microscopic life in asteroids as "inorganic residue", it just cannot deny visual evidence of life on Mars. So the obvious answer is to ensure the religiously controlled societies of Russ-ia and the USA never send microscopes to mars.
Now we'll get the usual tr-ools claiming the MACRO LENSES designed to look more closely at rocks for geological reasons are 'microscopes'- I've seen this lie repeated many times in the past. But obviously the level of maginification needed to see single cell or bacterialogical life is at a much greater level.
Different tro-lls try the "microscopes are a waste of time" lie. They use the argument "you'd nevber know if what was observed came from Mars or contamination from the probe during its time on Earth.
These excuses are same lame and transparent, you'd think only a very poor Gamma would fall for them. But the betas here swallow them up as intended everytime. Indeed Bet-as, far more than Gamm-as, are trained to swallow stat-ist lies from their ealiest years- just as Orwell described in 1984.
Alphas who cared to notice have accepted the proof of simple forms of extraterrestrial life across the solar system since maybe the late 1950s, and by implication the fact that life on Earth more than likely was seeded by pre-existing life. That Mars and/or the remains of the planet we now know as the 'asteroid belt' may have been part of the same ecosystem.
But alph-as do not believe in any organised religion, tho they may exploit or support the work of organised religions to control those they think are inferior and need controlling. So many evil aphas see no harm in having the knowledge of the widespead nature of simple life in our solar system kept from the ple-bs.
Then there is another issue. Allow proof of life on Mars, and then contend with the pressure to bring back samples to earth for DNA analysis. The issue being the fear many have of allowing this 'alien' contaminate to threaten the biological 'safety' of Earth. There are many dim bulbs at NASA who argue "allow the truth of life on Mars to be revealed, and then, whether you like it or not, someone will bring that life back here and threaten all of us with the uncertain impact of alien bugs".
Or-ganised re-ligions love the Status Quo, for it is always a construct they have worked tirelessly to create. And the leaders of or-ganised re-ligions, understanding the pack of lies their entities rely on, feel the ground is always on the verge of crumbling beneath their feet. Any fundamental change in Human Understanding could finally open the eyes of the shee-ple- lead to a widespread rejection of the evil nonsense that is organised religion.
Sadly their paranoia is unfounded. The shee-ple won't blink if microscopic life on Mars is utterly proven. But the paranoia still drives Russ-ian and American space policy. And therefore there will be no microscopes no Mars.
It would be worse than that, he'd still be in his cave trying to make fire and failing.
Well, Merriam-Webster has an entry for moonquake. Oxford lists marsquake. The Free Dictionary has sunquake. Dictionary.com lists starquake.
While the 14th century usage may have meant something else, it's certainly well known that the entire planet Earth does in fact quake during an earthquake. Why do you think remote sensors can detect earthquakes half way around the planet? Definitions of words change over a couple of years, let alone several centuries. In this case, I'd say the term "earthquake" as in the planet is more accurate than the original definition. But it becomes problematic when you're talking about a quake on another celestial body.
I also believe the "earth", as in dirt, that was referred to in the 14th century was generally referring to cultivable topsoil. You're not going to find much of that on the moon, mars, or a star.
because the entire Earth does not quake.
It does when Chuck Norris enters the South Pole.
We used to use words like seleneology and aresology, and then decided to simply to use geology, even when not on the Earth. Language evolves.

No real payload left Earth and it was all a giant scam to suck more $$$ into fake "research." All pictures and any video is real, but of fake computer rendered animations. So you should not believe what your own eyes see, nor what your brain thinks is real, but should instead believe the authoritative knowledge of the almighty AC on the Interwebz.
Also everyone knows Mars is just a flat thin 2D circle. If Elon goes there and NEVER comes back, then I will admit that I am wrong, but of course I'm not.
That's sort of correct, but the beauty of the Jovian moons is that they revolve around a planet that does have an atmosphere. So in principle they can use Jupiter's atmosphere to slow down to a speed that allows for slower passes around the moons (a la Galileo probe). I would think they'd be able to figure out how to get matched into a moon orbit so they can approach at a slow speed and only have to spend fuel to fight the moons gravity.
APK, go eat shit.

Jupiter's atmosphere is not as helpful as you might think. It will put you into a transfer orbit for a fly-by, but actually getting into a low orbit around those moons would require a huge rocket burn.
Its not the "moons gravity" that is the problem, but their velocity. Rocketry is all about the delta-V.
I'm no orbital mechanic, so I rely on reading the charts such as this one:
https://www.reddit.com/r/space...
You can see that even with aero-braking (on sections marked with red arrows), it is still far easier to land on Titan than the Jovian moons.
But don't take my word. NASA has so far landed only on Titan in the outer solar system.
Note also that it is way easier to escape the solar system, than to approach the sun, as the Parker Solar Probe is doing.

No. Near enough to vacuum. Mars atmosphere may be less than 1% of earth, but it is pea soup compared to those moons.
> The surface pressure of Europa's atmosphere is 0.1 Pa, or 10^12 times that of the Earth.[9]
Alright, but I don't see why having an atmosphere is a prerequisite for landing something on a planet. We landed people on the moon after all... in the 1960's! We even landed a probe on an asteroid.
Don't forget the important scientific term "bootyquake."
Earth does not only refer to the planet.
It also means: ground or soil.
So an earthquake on Mars makes the same sense as an earthquake on Earth.

Obviously not a necessity, but aero-braking makes the delta-V budget a lot easier. See the chart.
It actually takes a much bigger rocket to get a given payload to the lunar surface than to Mars, using aerobraking.

A Pascal is 100th of a millibar or 100,000th of earth atmospheric pressure. So 0.1 Pa is a 1,000,00th of earth pressure, or 10^-6, not 10^-12.
People will call me a hater or naysayer, but so what? They landed, for what is in all intensive purposes, our space junk on another planet. It is a great technological achievement no doubt. But why the hype? Mars is a dead planet. Humanity is not going to colonize space. We just can't work together.
Billions of people starve on this planet, and the USA is landing probes on Mars. lol k. What a load of crap and waste of money.
The surface pressure of Europa's atmosphere is 0.1 Pa, or 10^12 times that of the Earth.[9]
