“Gray skies blue” and “Wrong starting point” gigs on Fiverr

Aug. 24, 2014, under Web development

I’ve posted my first two gigs on Fiverr. For the bargain price of $5 each, you can get these services.

In my first gig, I’m offering to turn gray (or grey) skies blue:

I will take your cloudy day pictures and give them a nice cloudless blue sky in the background, lighter near the horizon as you will find in nature.

In the second gig, I’m offering to create a “you don’t belong here” page for Web sites:

Every site has one or more directories where visitors should not go. For example, if you have a directory with nothing but images in it, or include scripts, you would not want someone rummaging around through them. Put this file in those directories, and if a browser finds their way into one, it will send them back to your home page without revealing the contents of the directory.

You will receive a ZIP file containing a stand-alone XHTML Strict compliant HTML page file with no external dependencies, fully customized for your site.

If you can think of any other services I could reasonably offer for $5 each, I’d be interested in hearing your ideas…

The face on Mars – and other questions

Aug. 07, 2014, under history, opinions, philosophy, puzzling, space t/e/d

As it circled Mars on the 25th of July 1976, NASA’s Viking 1 orbiter photographed the Cydonia region of Mars. One of the frames included an image of a 2 km (1.2 miles) long mesa, situated at 40.75 degrees north latitude and 9.46 degrees west longitude, with the appearance of a humanoid face.

When the image was originally acquired, Viking chief scientist Gerry Soffen dismissed the “Face on Mars” in image 035A72 as a “trick of light and shadow.” In a press release issued on 31 July 1976, NASA provided a caption for the picture stating “The picture shows eroded mesa-like landforms. The huge rock formation in the center, which resembles a human head, is formed by shadows giving the illusion of eyes, nose and mouth. …”

Since it was originally first imaged, the “face” has been nearly universally accepted as an optical illusion. On 8 April 2001 the Mars Global Surveyor turned so it was looking at the “face” 165 km to the side from a distance of about 450 km. The resulting image has a resolution of about 2 meters (6.6 feet) per pixel in its full-resolution (2400 x 2400 pixels) version. As noted on the Malin Space Science Systems page, “If present on Mars, objects the size of typical passenger jet airplanes would be distinguishable in an image of this scale.”

The region was also studied by ESA’s Mars Express orbiter. Combining the MGS and Mars Express data, a three dimensional model of the “Face” was constructed.

After examining the higher resolution Mars Express and Mars Global Surveyor data NASA stated that “a detailed analysis of multiple images of this feature reveals a natural looking Martian hill whose illusory face-like appearance depends on the viewing angle and angle of illumination.” That certainly seems a plausible conclusion, especially in a universe where humans are the only intelligent species in a solar system which has never been visited by extraterrestrials, and civilization spontaneously appeared in Mesopotamia around 4,000 B.C.

In the high Andes mountains in South America, the Nazca plateau is covered with drawings that are best seen from the air. Popular belief is that they can only be seen from the air, but “more reasoned” analysis asserts they can be seen from the surrounding hills.

The designs are shallow lines made by removing reddish pebbles from the surface to uncover the whitish/grayish ground beneath. Hundreds are simple lines or geometric shapes; more than seventy are zoomorphic designs of animals, or human figures. Other designs include phytomorphic shapes such as trees and flowers. The largest figures are over 200 metres (660 ft) across. Who made them, and why? Theories abound, but every one of them is just that – a theory. No one really knows.

How were Egypt’s pyramids built? I don’t know, I wasn’t there at the time. Opinions differ, but I have a hard time swallowing some of the “scientifically acceptable” ones. Those stones are just too big and there are too many of them for the technology level that was supposed to have built the pyramids. There are also assertions that the Sphynx was thousands of years old when the pyramids were built. If that is true, who made the Sphynx? While we’re on it, where did the technology come from that was used to build Machu Picchu, nearly 8000 feet above sea level? A lot of those stones are so big we’d have a hard time moving them today, let alone placing them well enough that you can’t fit a piece of paper between them – yet there they are, built up for us to look at. How did that happen? Again, I wasn’t there at the time, so I can’t express anything more than an opinion on the matter – and my opinion is that we don’t have all of the answers.

If humanity and its civilization were to disappear (e.g., through nuclear war at the end of the oil supply, a disaster I’m trying to avert through Space Power Now), the pyramids would most likely still be there on the Cairo plain, even though effectively all of the other signs of our existence would be gone. The pyramids would probably be eroded, but their form would be easily distinguishable from space if the lighting and viewing angle were right, even in a low resolution image. If, for some reason, Earth’s atmosphere leaked away in the mean time, as has apparently happened to Mars, the recognizable life expectency of the pyramids would grow rapidly.

When a bullet hits a ball, different outcomes will occur, depending on the speed and size of the bullet, and the composition of the ball. A high speed bullet hitting a solid, brittle ball will cause the ball to shatter, for example. A slower projectile, such as a BB, will make a crater and embed itself in a softer ball. Somewhere between those extremes there’s a class of collisions with bizarre results: If a bullet going just the right speed, fast enough to tear through but slow enough to not completely explode it, hits a ball with a relatively soft center and a tough skin (think of an orange), a “mountain” will form at the entry point, and the skin on the opposite site will be torn off. The center of mass will change, conceivably to the point where the now-rough side that lost its skin is farther from the center of mass – at a “higher elevation” even though it just had its face blown off. The surface of Mars is remarkably close to this description: Olympus Mons, the tallest known mountain in the solar system, is in the smooth northern hemisphere, nearly diametrically opposite the giant Hellas crater situated in the southern highlands that have some of the roughest terrain on any planet in orbit around the Sun. I haven’t done an extensive analysis, but I have to wonder – was Mars hit by a cosmic bullet some time in the past that almost destroyed it?

Let’s consider for a moment a situation where our astronomers found a comet whose orbit was going to intersect the Earth’s in, say, ten years, and that the nucleus of the comet was big enough so there’d be no way to divert it: The Earth was going to die in ten years, and there’s nothing we could do about it. What would we do, in that case? I, for one, would be pushing real hard to build spaceships to carry at least some people to another planet. When they got to their destination, it could be thousands of years before the refugees would be able to start exploring out into the universe again: Chances are that something critical would be missing at their new home, and although humanity would survive, civilization would collapse. Recognizing that, what would be the best thing for the rest of us to do, so that once the survivors did get back on their feet, they could find their way home to see if anything was left of the world they came from? Put up a sign they could recognize from a long ways away, something to say “Hey you – come look here!” A face looking out into space would do the trick, I think. If there was uncertainty about which direction the comet was going to hit from, I’d even go as far as building four faces at the apexes of a regular tetrahedron, 120 degrees from each other in any direction, to improve the chances at least one would survive the impact.

It would probably be tens or hundreds of thousands of years, millions even, before the expatriats might come back, looking for something they couldn’t define. Over that time, anything smaller than the great pyramid of Cheops would probably erode away – it would take carving a mountain into the shape of a face to have any real hope of keeping the sign up long enough for it to be found. Before actually landing on the planet, our distant relatives, while initially startled by finding the Face, would probably get a closer look then dismiss it as “a natural looking … hill whose illusory face-like appearance depends on the viewing angle and angle of illumination.”

Wait a minute. What was that the NASA analysis decided?

Maybe it’s time we went and took a closer look – time for humans to go and look, not just our robots.

An interesting coincidence is that in 1958, almost two decades prior to the first images of the Face from the Viking probes, comic book artist Jack Kirby wrote a story entitled “The Face on Mars” for Harvey Comics (Race for the Moon Number 2, September 1958), in which a large face served as a monument to an extinct humanoid race from Mars. While Mr. Kirby’s face was standing vertically, and much smaller than the one found by Viking 1, his tale is eerily prescient of the discovery – something to make you go “hmm…”

Nuclear vs. solar power for deep space probes

Aug. 05, 2014, under history, opinions, space t/e/d

While checking to see if Space Power Now has started appearing in search engines, I came across an article in which the author implied that nuclear power supplies for satellites are inherently evil and dangerous. I have to disagree.

The ESA’s Rosetta comet explorer is scheduled to arrive at its target (comet 67P/Churyumov-Gerasimenko) Wednesday, 6 August, 10:45-11:45 CEST – about 27-28 hours from now as I’m writing this. (See the rosetta blog for current information.) Among other things, Rosetta has two solar panels, with a combined area of 64 m², each 14 m in length. The total span from tip to tip is 32 m. The solar panels power a suite of 11 science instrument packages, guidance computers, and the radio system for transmitting data back to Earth. They were only generating about 395 W when Rosetta was 5.25 AU (Astronomical Unit, roughly the distance from Earth to the Sun) from the Sun. Power output is now up to 850 W at 3.4 AU as the probe is encountering the comet and comet operations begin. According to the ESA, “The solar cells in Rosetta’s solar panels are based on a completely new technology, so-called Low-intensity Low Temperature Cells. Thanks to them, Rosetta is the first space mission to journey beyond the main asteroid belt relying solely on solar cells for power generation. Previous deep-space missions used nuclear RTGs, radioisotope thermal generators. The new solar cells allow Rosetta to operate over 800 million kilometres from the Sun, where levels of sunlight are only 4% those on Earth.”

Rosetta is a fine example of using advanced technology solar cells to operate at a greater distance from the Sun than was previously possible. However, somewhere beyond the orbit of Jupiter, collecting enough solar energy to run a reasonable set of instruments and a radio transmitter will become “difficult” in addition to using an inordinate percentage of the weight of a probe.

Nuclear power has been invented, the only way it could be “disinvented” would be to destroy civilization and any memory of it being used. Personally, I’d rather keep the nuclear power, and use it like a hammer, screwdriver, or other tool for productive purposes: I enjoy civilized life, which is why I’m as anxious as I am to make Space Power Now work.

Since Henri Becquerel discovered uranium salts emitted rays that resembled X-rays in their penetrating power in 1896, our understanding – and fear – of radioactive materials and radiation has grown. Radioactive materials, and equipment that utilize the radiation they produce, are potentially very dangerous if they are not properly handled. With due caution, they can be utilized to achieve objectives that would otherwise be impossible – like sending probes to the outer planets with enough instrumentation and radio power to return useful scientific data.

Tools are not evil, and should not be condemned as such: It is only when they are wielded by evil-minded people that tools cause evil results.
