Challenges of Getting to Mars

Fletch says...

@dag

Why wouldn't you try and improve on that method instead of going with a completely, untested extremely complicated new method? I suspect personalities and nerd egos are involved.


Are humans supposed to bounce across the surface in a balloon when/if we ever send a manned mission? Do you think that success or failure of this landing precludes learning anything from it? We don't get to send landers to Mars very often, so the opportunity for testing new procedures and techniques has to be taken when it can. Every little thing is done for a reason. If you think it's the result of "personalities and nerd egos", there are hundreds of books, TV specials, and documentaries out there that detail just about everything NASA has ever done, from inception to success or failure, as well as the people and personalities involved, that I think will change your mind. Here's a good place to start. Great book.

I understand that the sheer size of this rover (small car) makes it too big for a single bouncing-ball drop, but why not then, do two and let them come together and connect on landing?


Assuming you are serious...

The success rate of Mars missions is not good. On top of that are budget and launch window considerations. Are you really suggesting that TWO separate pieces be launched, have them both fly 150 million miles to Mars, enter orbit, BOTH successfully land (and land close enough they can find each other), find each other, and then connect somehow to make one rover just so they can use ballons? Really? Talk about complicated... It would take an incredibly huge nerd ego to even ATTEMPT to sell that idea. Even a single launch with two pieces on board would rely on the success of two completely separate and complicated landings and a meet-up before the rover mission could even begin. This also means the weight of each half of the rover would have to be reduced so two separate landing systems can be included. Less room for instruments. Less science. Anyhoo, this system is not so different from the previous rovers. They weren't just dropped from a parachute. The atmosphere is too thin for a parachute alone. RAD (rocket assisted descent) motors brought the rovers to a near dead stop about 50 feet above the surface and they were released. This landing also calls for more precision, as the landing zone is much more specific.

I gotta agree that wow, that is one hell of a sequence of events. And I have never seen video of real Earth tests of the various pieces of this.. you'd think there'd be cool video of at least some segments of this?

I'll be a bit heartbroken if this one dies. A car sized lander powered by the decay of 10+ pounds of plutonium. On top of that, it's nicely built: http://upload.wikimedia.org/wikipedia/commons/7/7b/Arm_and_Mast_of_NASA_Mars_Rover_Curiosity_533976main_pia13981-43_full.jpg

Questioning Evolution: Irreducible complexity

shinyblurry says...

@TheGenk @Skeeve @Boise_Lib @gwiz665 @packo @IronDwarf @MaxWilder @westy @BicycleRepairMan @shuac @KnivesOut

Evolution is pseudo-science. It exists in the realm of imagination, and cannot be scientifically verified. At best, evolution science is forensic science, and what has been found not only does not support it, but entirely rules it out. I don't think any of you realize how weak the case for evolution really is. None of them quotes, as far as I know, are from creation scientists btw

No true transitional forms in the fossil record:

Darwins theory proposed that slow change over a great deal of time could evolve one kind of thing into another. Such as reptiles to birds. The theory proposed that we should see in the fossil records billions of these transitional forms, yet we have found none. When the theory was first proposed, darwinists pleaded poverty in the fossil record, claiming the missing links were yet to be found. It was then claimed that the links were missing because conditions conspired against fossilizing them, or that they had been eroded or destroyed in subsequent fossilization.

120 years have gone by since then. We have uncovered an extremely rich fossil record with billions of fossils, a record which has completely failed to produce the expected transitions. It has become obvious that there was no process that could have miraculously destroyed the transitionals yet left the terminal forms intact.

The next theory proposed was "hopeful monster" theory, which states that evolution occurs in large leaps instead of small ones. Some even suggested that a bird could have hatched from a reptile egg. This is against all genetic evidence, and has never been observed.

The complete lack of transitional forms is not even the worst problem for evolution, considering the big gaps between the higher categories, and the systemic absence of transitional forms between families classes orders and phyla.

"I fully agree with your comments on the lack of direct illustration of evolutionary transitions in my book. If I knew of any, fossil or living, I would certainly have included them. You suggest that an artist should be used to visualise such transformations, but where would he get the information from? I could not, honestly, provide it, and if I were to leave it to artistic license, would that not mislead the reader?"

Dr. Colin Patterson, senior paleontologist at the British Museum of Natural History (and a hardcore evolutionist), in a letter to Luther Sunderland, April 10, 1979 admitting no transitional forms exist.

"Contrary to what most scientists write, the fossil record does not support the Darwinian theory of evolution because it is this theory (there are several) which we use to interpret the fossil record. By doing so we are guilty of circular reasoning if we then say the fossil record supports this theory."

Ronald R. West, PhD (paleoecology and geology) (Assistant Professor of Paleobiology at Kansas State University), "Paleoecology and uniformitarianism". Compass, vol. 45, May 1968, p. 216

"Lastly, looking not to any one time, but to all time, if my theory be true, numberless intermediate varieties, linking closely together all the species of the same group, must assuredly have existed. But, as by this theory, innumerable transitional forms must have existed, why do we not find them embedded in countless numbers in the crust of the earth?"

-Charles Darwin

"In fact, the fossil record does not convincingly document a single transition from one species to another."

-Evolutionist Stephen M. Stanley, Johns Hopkins University

Fossil record disputes evolutionary theory:

According to evolutionary theory we should see an evolutionary tree of organisms starting from the least complex to the most complex. Instead, what we do see in the fossil record is the very sudden appearance of fully-formed and fully-functional complex life.

If you examine the fossil record, you see all kinds of complex life suddenly jumping into existence during a period that evolutionists refer to as the "Cambrian explosion".

None of the fossilized life forms found in the "Cambrian period" have any predecessors prior to that time. In essence, the "Cambrian period" represents a "sudden explosion of life" in geological terms.

Evolutionists try to disprove this by stretching it over a period of 50 million years, but they have no transitional fossils to prove that theory before or during.

"The earliest and most primitive members of every order already have the basic ordinal characters, and in no case is an approximately continuous series from one order to another known. In most cases the break is so sharp and the gap so large that the origin of the order is speculative and much disputed"

-Paleontologist George Gaylord

What disturbs evolutionists greatly is that complex life just appears in the fossil record out of nowhere, fully functional and formed.

A major problem in proving the theory has been the fossil record; the imprints of vanished species preserved in the Earth's geological formations. This record has never revealed traces of Darwin's hypothetical intermediate variants - instead species appear and disappear abruptly, and this anomaly has fueled the creationist argument that each species was created by God.

-Paleontologist Mark Czarnecki (an evolutionist)

"It is as though they [fossils] were just planted there, without any evolutionary history. Needless to say this appearance of sudden planting has delighted creationists. Both schools of thought (Punctuationists and Gradualists) despise so-called scientific creationists equally, and both agree that the major gaps are real, that they are true imperfections in the fossil record. The only alternative explanation of the sudden appearance of so many complex animal types in the Cambrian era is divine creation and both reject this alternative."

-Richard Dawkins, 'The Blind Watchmaker', W.W. Norton & Company, New York, 1996, pp. 229-230

Evolution can't explain the addition of information that turns one kind into another kind

There is no example recorded of functional information being added to any creature, ever.

"The key issue is the type of change required — to change microbes into men requires changes that increase the genetic information content, from over half a million DNA ‘letters’ of even the ‘simplest’ self-reproducing organism to three billion ‘letters’ (stored in each human cell nucleus)."

Species just don't change. Kind only produces kind:

"Every paleontologist knows that most species don't change. That's bothersome....brings terrible distress. ....They may get a little bigger or bumpier but they remain the same species and that's not due to imperfection and gaps but stasis. And yet this remarkable stasis has generally been ignored as no data. If they don't change, its not evolution so you don't talk about it."

Evolutionist Stephen J. Gould of Harvard University

Not enough bones:

Today the population grows at 2% per year. If we set the population growth rate at just 0.5% per year, then total population reduces to zero at about 4500 years ago. If the first humans lived 1,000,000 years ago, then at this 0.5% growth rate, we would have 10^2100 (ten with 2100 zeroes following it) people right now. If the present population was a result of 1,000,000 years of human history, then several trillion people must have lived and died since the emergence of our species. Where are all the bones? And finally, if the population was sufficiently small until only recently, then how could a correspondingly infinitesimally small number of mutations have evolved the human race?

"Evolutionism is a fairy tale for grown-ups. This theory has helped nothing in the progress of science. It is useless."

-Professor Louis Bounoure, past president of the Biological Society of Strassbourg, Director of the Strassbourg Zoological Museum and Director of Research at the French National Center of Scientific Research.

More fun facts:

There are no records of any human civilization past 4000 BC

"The research in the development of the [radiocarbon] dating technique consisted of two stages—dating of samples from the historic and prehistoric epochs, respectively. Arnold [a co-worker] and I had our first shock when our advisors informed us that history extended back only for 5,000 years . . You read statements to the effect that such and such a society or archeological site is 20,000 years old. We learned rather that these numbers, these ancient ages, are not known accurately; in fact, the earliest historical date that has been established with any degree of certainty is about the time of the First Dynasty of Egypt."—*Willard Libby, Science, March 3, 1961, p. 624.

Prior to a certain point several thousand years ago, there was no trace of man having ever existed. After that point, civilization, writing, language, agriculture, domestication, and all the rest—suddenly exploded into intense activity!

"No more surprising fact has been discovered, by recent excavation, than the suddenness with which civilization appeared in the world. This discovery is the very opposite to that anticipated. It was expected that the more ancient the period, the more primitive would excavators find it to be, until traces of civilization ceased altogether and aboriginal man appeared. Neither in Babylonia nor Egypt, the lands of the oldest known habitations of man, has this been the case."—P.J. Wiseman, New Discoveries, in Babylonia, about Genesis (1949 ), p. 28.

Oldest people/language recorded in c. 3000 B.C., and were located in Mesopotamia.

The various radiodating techniques could be so inaccurate that mankind has only been on earth a few thousand years.

"Dates determined by radioactive decay may be off—not only by a few years, but by orders of magnitude . . Man, instead of having walked the earth for 3.6 million years, may have been around for only a few thousand."—*Robert Gannon, "How Old Is It?" Popular Science, November 1979, p. 81.

Moonwalk disproves age of moon:

The moon is constantly being bombarded by cosmic dust particles. Scientists were able to measure the rate at which these particles would accumulate. Using their estimates according to their understanding that the age of the Earth was billions of years, their most conservative estimate predicted a dust layer 54 feet deep. This is why the lander had those huge balloon tires, to be prepared to land on a sea of dust. Neil Armstrong, after saying those famous words, uttered two more which disproved the age of the moon entirely "its solid!". Far from being 54 feet, they found the dust was 3/4 of an inch.

Evolution is a fairy tale that modern civilization has bought, hook line and sinker. Humorously, atheists accuse creationists of beiieving in myths without any evidence..when they place their entire faith in an unproven theory even evolutionists know is fatally flawed and invalid. Evolution is a meta physical belief that requires faith. Period.

Evolution is false, science affirms a divine Creator

Dan Savage on Sex, Religion & Bullying

WKB says...

Dan Savage is such a great guy. I've been a fan of his column for years, but this recent YouTube campaign is really something special. The It Gets Better campaign is one of the most moving, if not the most moving, grass roots uses of modern technology that I know of. It is so awesome to see a movement fueled by average folks be so obviously right and powerful that celebrities and world leaders have to scramble to catch up to it.

He should, and I'm sure he will eventually, get an award for his work that he doesn't have to buy from Ann Lander's estate.

Actually, weight doesn't have anything to do with it. It's mass. In that, Spock is still wrong, but so are you.


http://hyperphysics.phy-astr.gsu.edu/hbase/mass.html
Weight is the effect of gravity on an object based on its mass. The black hole is a nearby source of gravity, so the amount of mass on the ship will make it heavier. Just like it takes all the huge boosters on our space shuttles when leaving Earth's gravitational field, but only the small lander's power when leaving the moon.

So I'm correct!

Found one of these with a broken coin slot (someone had turned on the infinite quarters switch) and spent most of an afternoon having a competition with a friend seeing who could go the fastest straight down before crashing. IIRC you would "abort" button to get some altitude then spin upside down (expert mode) and wall the throttle, adjusting to get into a crevass, not into the side of a mountain.

Good times. Good times.

Totally! From what I heard Grumman was pretty proud of their original design and had convinced NASA to bust the Apollo lander out of the Air & Space Museum and use it for the next trip to the moon, but then some wiseguy said "AYFKM?!" and so they hired one of the most talented game developers on the planet to design a new one. I don't get it, personally, but I hope Carmack is able to leapfrog this achievement directly into the Oval Office.
