It's Just One Boring Day After Another. Photo Courtesy Zazzle.com, UK
I don’t know about you, but my life most weeks is pretty routine. Even though I work in a setting where no two days are the same, in some respects (I never know which patients I’ll be seeing or what their issues will be) my schedule is predictable, Monday through Friday, with a night of being on-call every other week (One thing is certain, here. If you get called in the night, it’s never good! Chaplains don’t get called for the happy stuff at night—that’s just a given. And with our large service area and being a Trauma II hospital, it’s a rare night I don’t get called).
With that in mind, I look to other sources to provide the unique, the unexpected, the stunning, the beautiful, the historic. What takes my breath away? Beauty where there should only be the drab. Inspiration from the simplest of the simple where there should only be plainness. And historic perspectives never glimpsed by the human eye.

We’ve gotten used to the magnitude of the beauty of the galaxy from photos by the Hubble Space Telescope, or the Twin Keck’s on Mauna Kea’s lofty peak, or composites made possible by the digitization of multiple pictures of the same object taken in various light spectra by different space and earth-based observatories.

probe expeditions to the gas giants, Jupiter and Saturn, such as Galileo and Cassini, respectively, not to mention the earlier Voyagers, have so completely revised our understanding of those miniature solar systems that astronomy textbooks written even five years ago are hopelessly out of date. In a century Mars has gone from a planet believed to have a struggling civilization, to a dusty, dead, rocky world with no potential, back to a world of potential and interesting; the search for life in space has zeroed in on it as prime suspect #1. The discovery and confirmation of water ice, just inches below

its surface is reigniting the global interest to send a human crew to investigate, even though the political and economic chaos rippling around the makes the realization of that dream tenuous at best. Saturn’s moon Titan has now been to be discovered to be so earthlike, although its rains, and rivers and oceans are of methane that astronomers are stunned and rewriting what a planet is and what an active environment can be every few months. I could go on and on.

The picture below fits into the category of “Historic Views Never Seen Before by Human Eyes”. The photographer is the European Space Agency’s Rosetta Space Probe launched in 2004 whose ultimate destination is the comet, 67P/Churyumov-Gerasimenko, which it is scheduled to reach in 2014. Like a miniature Casinni-Huygens, Rosetta will launch a probe, the Philae Lander to the surface of the comet and gather data to be radioed back to Earth. So it has a way to go, but is on track to make its target date. Rosetta’s trajectory is a gravity-assisted boost cycle, circling the Sun and planetary flybys to increase its speed and set it up for its ultimate goal.
Along the way, Rosetta has encountered several asteroids, the most recent being 21 Lutetia. This is the last asteroidal encounter before the probe is put into deep space hibernation as it flies toward the comet.

Just released is one of those stunning photos, historic in that no human eye has ever seen 21 Lutetia other than as a dim dot of light, but in the distance is the grand dame of the Solar System, Saturn. The black of space punctuated by a small asteroid—a piece of the earliest solar system—in the foreground and in the distance—massive Saturn, millions of miles distant but still unmistakable with its signature rings. The asteroid photo, taken from a distance of 22,300 miles, shows it is approximately 81 miles on its long axis. Such stark beauty of the very small and the massive opposite in their juxtaposition against the eternal night of deep space takes my breath away!

I end with these prescient verses written nearly 300 years ago by a man who could only imagine in the most rudimentary fashion the reality of deep space, but ended up describing it with a beauty in word, expressing an amazingly close reality of what we know today:
Of man, what see we but his station here,
From which to reason, or to which refer?
Thro’ worlds unnumber’d tho’ the God be known,
‘Tis ours to trace him only in our own.
He, who thro’ vast immensity can pierce,
See worlds on worlds compose one universe,
Observe how system into system runs,
What other planets circle other suns,
What vary’d being peoples every star,
May tell why heav’n has made us as we are.
by Alexander Pope, OF THE NATURE AND STATE OF MAN WITH RESPECT TO THE UNIVERSE, from The Essay on Man, Epistle 1. 1732
21-Lutetia Close Up: An Update
The European Space Agency has released another image of 21-Lutetia taken by Rosetta at a distance (astronomically speaking) of only 1965 miles. That’s approximately the same distance as flying from San Francisco to Indianapolis, non-stop. Or, if you live East of the Mississippi, from Washington, D.C. to Phoenix, Arizona.

The July 10 flyby was a spectacular success with Rosetta performing faultlessly. Closest approach took place at a distance of 1,965 miles (3,162 kilometers).
The images show that Lutetia is heavily cratered, having suffered many impacts during its 4.5 billion years of existence. As Rosetta drew close, a giant bowl-shaped depression stretching across much of the asteroid rotated into view. The images confirm that Lutetia is an elongated body, with its longest side around 81 miles (130 km).
The pictures come from Rosetta’s Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) instrument, which combines a wide-angle and a narrow-angle camera. At closest approach, details down to a scale of 200 feet (60 meters) can be seen over the entire surface of Lutetia.
