Cacti and Desert Flora of the Great Southwest

Again, May 22 is the International Day for Biological Diversity. Postcard US-3971360 to Japan shows various cacti and desert flora of the Great Southwest.

USPS issued the Sonoran Desert sheet in Tucson, Arizona on April 6, 1999 that contained ten 33¢ stamps. It was the first of twelve self-adhesive stamp sheets Nature of America that USPS released annually between 1999 and 2010.

Diesel Train in the Royal Gorge

Postcard US-3689818 to Russia shows a diesel train in the Royal Gorge, on the Arkansas River, passing underneath the Suspension Bridge - "The World's Highest Bridge", near Cañon City, Colorado, Cañon City, with a population of 16,400 as of 2010 and known as the "Corrections Capital of the World for having nine state and four federal prisons and penitentiaries, is one of the few U.S. cities that have an eñe in its official name.

Two train stamps, among others, were affixed to the card. One was a 33-cent "The Congressional of the Pennsylvania Railroad" from a set of five 1999 stamps entitled All Aboard! 20th Century American Trains. The other “Untitled (Trains on Inclined Tracks),” showing a gouache, colored pencil, and graphite drawing on pieced paper from circa 1960–1963, was one of the five Forever stamps, issued on March 26, 2015, featuring the work of Mexican artist Martín Ramírez who had been confined to psychiatric hospitals for more than 30 years.

I had the sender's address since November 6, 2015. However, the card didn't get posted until December 4, 2015 due to delay from my training for my first half marathon and my encounter of a failed armed robbery. The card had since expired after 60 days, and it was automatically registered by Postcrossing on May 11, 2016 when the account of the receiver was closed.

I Left my Heart {at Hyde and Lombard Street} in San Francisco

As a captured audience inside the Terminal 2 at the SFO International Airport waiting for my return flight to Las Vegas, I found a rack full of "I left my heart in San Francisco" postcards. Outgoing postcard US-3373240 to Ukraine was one of those that I obligatorily purchased.

The card shows a section of Lombard Street in the Russian Hill neighborhood, a one-way block between Hyde Street and Leavenworth Street, known as the crookedest street in the world with eight sharp turns.

That section of Lombard Street used to be a straight, cobblestone street with a 27% grade which was too steep for most cars. The turns were built in 1922 so that people could drive up and down the hill, until the street was made one-way downhill in 1939. The street was paved with red bricks and about 250 steps were built on each side of the street to accommodate pedestrians.

Now, during the peak tourist season in summer, there are as many as 350 cars driving down the street each hour. However, it was not a popular tourist destination until the late 1950s. I drove down the street twice during my previous visit to San Francisco in 1999. This time, I took the Powell-Hyde cable car to the top of this block earlier today, and took the steps down to Leavenworth Street.

Eagle Nebula Pillars

25 years ago on April 24, 1990, Space Shuttle Discovery blasted off the Kennedy Space Center in Florida on mission STS-31 with the Hubble Space Telescope (HST) on board. Fitting with a 2.4-meter or 7.9 feet mirror and instruments observing in the near ultraviolet, visible, and near infrared spectra, the telescope has since recorded some of the most detailed images ever, leading to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.

The Eagle Nebula (NGC 6611) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux between 1745 and 1746. It contains several active star-forming gas and dust regions that became famous when NASA release a HST image "Pillars of Creation" in 1995, capturing three dusty pillars in the Eagle Nebula. HST recently took another photograph at the star-forming pillars with its newest camera, providing much greater details.

In celebration of HST’s 25th anniversary, 32 of the best HST images were competing against each other in a series of head-to-head competitions, with popular votes deciding the winner of each round. Ultimately, with over 17,000 votes the Eagle Nebula Pillars triumphed over all other competitors to become the winner of Hubble Mania 2015.

In this NASA released image that can be made into a 5"x7" postcard under NASA's copyright notice, three pillars of cold hydrogen gas and dust in the Eagle Nebula are shown as the birthplace of new stars, 6,500 light years away. The pillars are bathed in the blistering ultraviolet light from a grouping of young, massive stars located off the top of the image. Streamers of gas can be seen bleeding off the pillars as the intense radiation heats and evaporates it into space. Denser regions of the pillars are shadowing material beneath them from the powerful radiation.

I was fortunate for being able to witness the Space Shuttle Discovery's launch for the 3rd Hubble Space Telescope Servicing Mission STS-103 at the Kennedy Space Center in Florida on December 19, 1999.
