Where We’ve Been

Category: science, spaceSteve @ 23:34 pm

After the last few nausea-inducing posts, this one is merely awe-inspiring.  This is a National Geographic depiction of space flight missions.   From the Nat Geo site:

Of the nearly 200 solar, lunar, and interplanetary missions depicted on this map, most have been [to] Earth’s nearest neighbors.  As rocketry, navigation, and imaging have become ever more capable and reliable, the planets and many of their moons have been examined in detail.  The New Horizons mission to Pluto is under way, as is the MESSENGER mission to Mercury.

Penguin Poop From Space

Category: science, spaceSteve @ 02:38 am

penguins Penguin Poop From SpaceWho says we don’t get payback from all the investment we’ve put into space?  Here’s a cool story from the – no kidding – Himalayan Times:

WASHINGTON: Scientists looking for lost penguins stumbled upon an effective method: Follow their excrement from space.

In remote Antarctica, about one-and-a-half times bigger than the United States, researchers have been unable to figure out just where colonies of emperor penguins live and if their population is in peril. It is harder still because emperor penguins, featured in the film “March of the Penguins,” breed on sea ice, which scientists say will shrink significantly in the future because of global warming.

Because the large penguins stay on the same ice for months, their excrement stains make them stand out from space. Scientists at the British Antarctic Survey found this out by accident when they were looking at satellite images of their bases.

A reddish-brown streak on the colorless ice was right where they knew a colony was, said survey mapping scientist Peter Fretwell. The stain was penguin excrement – particularly smelly stuff – and it gave researchers an idea to search for brown stains to find penguins. They found the same telltale trail, usually dark enough to spot from space, all over the continent, said Fretwell by telephone from England.

Using satellite data, the scientists found 10 new colonies of penguins, six colonies that had moved from previously mapped positions to new spots and another six that seemed to have disappeared. Overall, 38 colonies were spotted from above, according to Fretwell’s paper, “Penguins From Space” in the journal Global Ecology and Biogeography.

The research is “incredibly useful,” because the only time to see emperors are during breeding in winter when weather makes it nearly impossible to get to the colonies, said longtime penguin researcher William Fraser, who wasn’t involved in the study. Fraser noted that salty penguin guano “over time will corrode your boots,” adding that he has lost nearly a dozen pairs to it in 35 years of penguin research.

Where Were You 23 Years Ago?

Category: miscellaneous, spaceSteve @ 04:25 am
Challenger Explosion

Challenger Explosion

There are defining moments in a person’s life against which other things are measured. Those are different for each person and for each generation. 9-11 has become that moment for this generation, and if you ask, ‘Where were you when you heard about 9/11?’ virtually everyone could give you a clear answer.

Before that particularly evil day, the defining event for a generation was probably the Challenger disaster. I remember very clearly where I was on Jan 28, 1986 when I heard the news that the shuttle had blown up. I was a young lieutenant at a space-tracking radar station in Massachusetts and had just come off the midnight shift. I was barely asleep when my roommate burst into the room, yelling that the shuttle had just exploded. We flipped on the news and watched that clip over
and over again, struck dumb at the enormity of the tragedy.

The event devastated DoD and NASA space programs for years afterward. To this day I’m still amazed that Congress had the intestinal fortitude to allow those programs to restart.

Where were you on that day? Did it affect you?

Advent Space Pics Calendar

Category: creation, faith, science, spaceSteve @ 23:00 pm

1 Zwicky 18 galaxyLaura at Pursuing Holiness tipped me to this excellent advent calendar made pics from the Hubble Space Telescope.  As a long-time space geek, I’ve long been aware of (and amazed by) the incredibly artistic hand of God in space.  I’ll also take the liberty to borrow her quote from Michael at Wizbang:

I can’t help but marvel at the fact that God, who revealed Himself so majestically in the heavens, also chose to beget Himself as a lowly Son of Man, so that mankind, a thoroughly insignificant creature when compared to the vastness of Creation, could be reconciled with Him and receive an abundant and everlasting life.

Amen and amen.  Have a blessed Christmas season.

God is Revealed in the Heavens

Category: creation, faith, science, spaceSteve @ 19:43 pm

I’m a space geek and I’m continually amazed by beauty of the artistry of God as displayed in the heavens.  I’m also amazed the lengths that people will go to in order avoid seeing His hand.  This is the Cone Region (aka the Christmas Tree Cluster) and the Fox Fur Nebula.  Click for full-sized image.

FOXNews.com – ‘Oh Great’: Astronaut Loses Tool Bag During Spacewalk

HOUSTON — A spacewalking astronaut accidentally let go of her tool bag Tuesday after a grease gun inside it exploded, and helplessly watched as the tote and everything inside floated away.

It was one of the largest items ever to be lost by a spacewalker, and occurred during an unprecedented attempt to clean and lube a gummed-up joint on a solar panel.

Heidemarie Stefanyshyn-Piper was just starting to work on the joint when the mishap occurred.

She said her grease gun exploded, getting the dark gray stuff all over a camera and her gloves. While wiping off herself, the white, backpack-size bag slipped out of her grip, and she lost all her other tools.

“Oh, great,” she mumbled.

If I dropped a toolbag from 250 miles up, I’d probably say something a bit more colorful

China to Remake ‘Capricorn One’

Category: news and politics, science, spaceSteve @ 09:08 am

I’m a career space guy and I’m always encouraged to see nations and private citizens advancing space exploration, but sometimes technology doesn’t cooperate, so you have to be ready with a Plan B.  Or at least the Chinese think so.  They probably just launched three astronauts.

With a burst of flame and smoke, a Chinese rocket blasted off into orbit yesterday. But it was the state news agency that moved faster than the speed of light, publishing the transcript of an “in-space” conversation between the astronauts before they had even left Earth.

The Xinhua news agency posted an article on its website breathlessly describing the Shenzhou VII spacecraft in orbit and quoting exchanges between the crew, possibly during the most important part of the mission: China’s first spacewalk. The only problem was that the crew were still on terra firma.

The story had disappeared by the end of the day and its appearance was described as a technical error.

Gotta love those ‘technical errors’.  Somebody just earned themselves a 9mm aneurysm and an early retirement.

(ORA:  Capricorn One)

Arguing About Stars

Category: faith, science, spaceSteve @ 13:38 pm

“Like all sciences, astronomy advances most rapidly when confronted with exceptions to its theories…”   (An Introduction to Modern Astrophysics, Bradley Carroll & Dale Ostlie)

“By the word of the LORD were the heavens made, their starry host by the breath of his mouth.”  (Psalm 33:6, NIV)

Contemporary thought in astronomy and cosmology says that stars start life as clouds of dust in the vast emptiness of space.  These clouds are compressed through collisions or by blast waves from supernovae and may eventually condense into one or more stars.  Stars then go through a multi-billion year lifecycle:

Most stars, including the sun, are “main sequence stars,” fueled by nuclear fusion converting hydrogen into helium. For these stars, the hotter they are, the brighter. These stars are in the most stable part of their existence; this stage generally lasts for about 5 billion years.

As stars begin to die, they become giants and supergiants (above the main sequence). These stars have depleted their hydrogen supply and are very old. The core contracts as the outer layers expand. These stars will eventually explode (becoming a planetary nebula or supernova, depending on their mass) and then become white dwarfs, neutron stars, or black holes (again depending on their mass).

Smaller stars (like our Sun) eventually become faint white dwarfs (hot, white, dim stars) that are below the main sequence. These hot, shrinking stars have depleted their nuclear fuels and will eventually become cold, dark, black dwarfs.

HR diagram [This obviously presupposes that God is nowhere in sight, and has no hand in stellar creative activities.]  So color and luminosity are generally linked to a star’s temperature, as shown in the “H-R Diagram” to right.  Or so most astronomers believe. 

Since the color of a heated body depends on temperature, the different classes take on different, though subtle, colors, from slightly reddish for class M to orange for K, through yellow- white to bluish for classes B and O. Star colors can be noted rather easily even with the unaided eye, especially when those close together contrast against each other. Stars of classes L and T, none of which are visible to the naked eye, range from red through deep red to “infrared” (these optically invisible under any circumstances).

Not necessarily so, some would argue.

There are a group of astronomers, astrophysicists and cosmologists who hold to the Electric Universe theory, which contends that electrical charges acting in space offer a better explanation for ‘The Way Things Are’ in space.

There are stars that violate the standard model of stellar evolution. Stars that are too cool and too small for atomic fusion to take place in their cores have caused astronomical researchers to scramble for explanations. Since stars are supposed to have a mass of at least 75 times that of Jupiter for fusion reactions to occur, another speculative mechanism for what powers them has been suggested: gravitational collapse. In other words, gravity is pulling the cold, dark star into greater compaction, which must be what is creating the additional heat and x-ray emissions.

“In the ES [Electric Star] model, perhaps the most important factor in determining any given star’s characteristics is the strength of the current density in Amperes per square meter (A/m2) measured at that star’s surface. If a star’s incoming current density increases, the arc discharges on its surface (photospheric tufts) will get hotter, change color (away from red, toward blue), and get brighter. The absolute brightness of a star, therefore, depends on two things: the strength of the current density impinging into its surface, and the star’s size (the star’s diameter). Therefore, we add another scale to the horizontal axis of the HR diagram: Current Density at the Star’s Surface.”

The really interesting bit is that NASA and the established space community want nothing to do with such a view of the cosmos.  That’s not surprising, because the folks at Thunderbolts, one of the primary Electric Universe web sites, describe their theory this way:

Electric Universe [challenges] “the myths of ‘Big Bang’ cosmology, and does so without resorting to black holes, dark matter, dark energy, neutron stars, magnetic ‘reconnection,’ or any other fictions needed to prop up a failed theory.

To NASA and much of academia, such a view seems to be as dangerous an idea as a loving God who “determines the number of the stars and calls them each by name.”

The earth, the stars and all of Creation provide a general revelation of the nature and hand of God.  The more we learn in any field of scientific observation, the more we see His hand in everything.  We can argue about the specifics of the pieces, and how they all fit together, but we can’t escape the growing evidence that the hand of God was and is behind it all.

“You alone are the LORD. You made the heavens, even the highest heavens, and all their starry host, the earth and all that is on it, the seas and all that is in them. You give life to everything, and the multitudes of heaven worship you.”  (Nehemiah 9:6, NIV)

The Heavens Declare

Category: faith, science, spaceSteve @ 14:51 pm

NGC-6357_Pismis24As a long-time space geek, I have always been amazed by the beauty and majesty of the heavens.  The Hubble Space Telescope and other space media sources pour forth incredible image after incredible image.  But that’s not the only thing that pours forth.  Psalm 19 says this:

“The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge. There is no speech or language where their voice is not heard. Their voice goes out into all the earth, their words to the ends of the world. In the heavens he has pitched a tent for the sun.”  ( Psalm 19:1-4a, NIV )

Everything that is seen and unseen reveals the hand of God.  All you have to do is look up.  Then again, even if you want to put your head in the sand, you’ll find Him there, too.

With that in mind, I’ve added a page dedicated to the hand of God as revealed in space imagery.

Space Shuttle Pre-Launch Processing

Category: spaceSteve @ 11:43 am

windowslivewriterspaceshuttleprelaunchprocessing a4e8crawler thumb 1 Space Shuttle Pre Launch Processing There’s a great series of images at PicDit showing shuttle processing, from arrival and integration of major components to transportation to the launch site to the launch itself. 

Here’s a bit of trivia: the transporter/crawler that delivers the shuttle to the pad travels the 3.5 mile distance in a little over 8 hours.  I think I was driving behind it on Academy Boulevard today.  It had its blinker on the whole way.
