I was in my freshman year in high school and remember the elation I felt after months of failed Project Vanguard flights in the wake of the Russian Sputnik launches.

Entering the Space Age

Through the combined efforts of JPL and the Army Ballistic Missile Ballistic Agency, Explorer 1 launched from Cape Canaveral, Fla., on Jan. 31, 1958. There was a nail-biting wait before tracking stations confirmed that Explorer 1 had gone successfully into orbit around Earth. With the launch of Explorer 1, the United States officially entered the space age.

You may have noticed the “Damsel’s Water Zen” widget in the sidebar. This is the background behind it.

Damsel likes the light patterns that water makes when sunlight dances through it. Whether in a swimming pool, in a river, in a marina channel or in a shallow harbor, it doesn’t matter, she likes the shimmering ripples.

Last September (2007), we spent our anniversary, as usual, on Catalina Island. We go to Avalon every year since that’s where we got married. While we were there, we took a lot of pictures and a few movies.

While we were waiting on the Green Pier for our glass-bottom boat tour. I leaned over the rail and captured this short sequence of the rippling water in the harbor. I used my little Canon A710 IS digital camera in AVI mode. I pointed the camera straight down and captured about ten seconds of video. When I showed the preview to Damsel, she said it was relaxing like ‘Water Zen.’

So, when we got home, I converted the short video to Flash® and popped it in the sidebar as a remembrance to our time in Avalon and an opportunity to ‘gaze and relax.’

President Bush will be paying a visit to Robinson Helicopter in Torrance, California tomorrow. That’s about a mile and a half from our house. We’d like to go see and hear the President, but admission is by invitation only.

Bush to visit Torrance on Wednesday

President Bush will pay a visit to Robinson Helicopter Co. in Torrance on Wednesday as he urges Congress to pass three free trade agreements.

Bush will take a tour of the company, which is the world’s largest manufacturer of civilian helicopters, and deliver remarks to employees.

Robinson Helicopter posted a record year in 2007, largely on the strength of its exports to 55 countries. Much of that success is due to the declining value of the dollar, which makes American exports less expensive to foreign customers.

“We’re an unusual story because we’re not outsourcing everything,” said Kurt Robinson, a company vice president. “I think it’s pretty exciting that we get the president here. It’s fun to show off American manufacturing.”

In his State of the Union Address on Monday night, Bush urged Congress to approve trade deals with Colombia, Panama and South Korea, which would reduce or eliminate tariffs on American-made goods.

“These agreements will level the playing field,” Bush said. “They will give us better access to nearly 100 million customers. And they will support good jobs for the finest workers in the world: those whose products say ‘Made in the USA.’”

Wadcutters tend to cut nice, clean holes in a paper target. A wadcutter is a bullet specially designed for shooting paper targets, usually at close range and with significantly subsonic velocities under 800 ft/s (244 m/s) such as are found in handgun and airgun competitions.

A wadcutter has a flat or nearly flat front, which acts to cut a very clean hole through the target, making it easier to score and ideally reducing errors in scoring to the favor of the shooter.

Occasionally, a grouping can resemble a celebrity mouse if you orient the target just right:

The last storm brought the snow level in the San Gabriel Mountains down to about the 3000 foot level. I snapped this shot of some of the mountain peaks as we drove to the gun show today. More on the show later.

As this is being written, the rain has begun again, and will likely add to the snow in the mountains.

Today we took a detour down by the ocean on our way for the weekly grocery shopping. It was just after a rain last night and the winds were whipping. We stopped at the L.A. Harbor breakwater by Cabrillo Beach and saw a number of sea birds including sandpipers, Caspian Terns, pelicans and several varieties of seagulls. The gull in the picture is a Heermann’s Gull, characterized by its black legs and feet and its red bill. Click on the picture to see the 1024×768 version in the image viewer.

From Wikipedia:

The Heermann’s Gull (Larus heermanni) is a gull resident in the United States and Mexico. Of the current population of about 150,000 pairs, 90% nest on the island of Isla Rasa off Baja California in the Gulf of California, with smaller colonies as far north as California and as far south as Nayarit. After breeding, birds commonly disperse to central California, and less commonly north as far as British Columbia and south as far as Guatemala. They are usually found near shores or well out to sea, very rarely inland.

MESSENGER, a spacecraft probe sent to explore the innermost planet, imaged the planet in multiple spectra last week. NASA/JHU image technologists re-assembled the image into colors detectable by the human eye. The result is this beautiful rendering of the delicate colors of Mercury. Click the image to enlarge.

By the way, Mars Rover OPPORTUNITY has been on the surface of the red planet for four Earth years as of today. Rover SPIRIT passed the four-year milestone January 3, three weeks ago. Congratulations to the Rover Team.

Here’s the MESSENGER article about this image.

Mercury - in Color!

One week ago, the MESSENGER spacecraft transmitted to Earth the first high-resolution image of Mercury by a spacecraft in over 30 years, since the three Mercury flybys of Mariner 10 in 1974 and 1975. MESSENGER’s Wide Angle Camera (WAC), part of the Mercury Dual Imaging System (MDIS), is equipped with 11 narrow-band color filters, in contrast to the two visible-light filters and one ultraviolet filter that were on Mariner 10’s vidicon camera. By combining images taken through different filters in the visible and infrared, the MESSENGER data allow Mercury to be seen in a variety of high-resolution color views not previously possible. MESSENGER’s eyes can see far beyond the color range of the human eye, and the colors seen in the accompanying image are somewhat different from what a human would see.

The color image was generated by combining three separate images taken through WAC filters sensitive to light in different wavelengths; filters that transmit light with wavelengths of 1000, 700, and 430 nanometers (infrared, far red, and violet, respectively) were placed in the red, green, and blue channels, respectively, to create this image. The human eye is sensitive across only the wavelength range 400 to 700 nanometers. Creating a false-color image in this way accentuates color differences on Mercury’s surface that cannot be seen in the single-filter, black-and-white image released last week.
