McMath-Pierce Solar Telescope – 2

The Mirrors

MichaelStephenWills1 Comment

These views within the McMath–Pierce solar telescope enclosure were captured during a guided tour of the instrument, April 20, 2005. By way of orientation, think of yourself at the location labeled “4” on this model. This is the only large telescope where humans can view the interior and visually experience the light paths “bouncing” between the mirrors.

McMath–Pierce solar telescope has three heliostats mounted on a 110-foot tower adjacent to a slanted enclosure. The 2.03-meter heliostat feeds a 1.61-meter primary mirror, there are 1.07-meter and 0.91-meter primary mirrors fed by a pair of 0.81-meter heliostats. Here we are inside the slanted enclosure, looking up the shaft to the tower mounted heliostats, readily identified as the three circles, the largest at center (3.51 feet in diameter). The smaller (2.66 feet) heliostats named “East” (on left) and “West.”

Built in 1962, the building was designed by American architect Myron Goldsmith and Bangladeshi-American structural engineer Fazlur Rahman Khan. It was the largest solar telescope and the largest unobstructed aperture telescope in the world. It is named after the astronomers Robert Raynolds McMath and Keith Pierce. Painted white to reflect sunlight to reduce heat accumulation, the enclosure is water cooled to prevent convection currents through the column of air within the slanted enclosure, keeping the air as still as possible along the light path between the mirrors.

In the three photographs following, we face the underground portion of the slanted shaft and (what looks to be) the 0.91 meter (2.99 feet) primary concave mirror. I say that because in some of the photographs a beam of light, to the left of the mirror, can be seen travelling further underground, presumably to the largest primary mirror. As there is only one such light beam, I conclude the west heliostat is inactive.

Here we looking up the slanted enclosure. Look carefully at the first photograph, below, to see reflections on the glass partition. The observation platform was separated from the light paths to maintain the stillness of the air column. The two mirrors of the first photograph are the third mirror, reflecting concentrated sunlight from the 0.91 and 1.61-meter primary mirrors into the observatory rooms. The mirror for the 1.07-meter primary is out of sight in foreground, I believe this set of three mirrors (West heliostats, primary and third) was out of service.

The second photograph, on right, is a close up of the third mirror for the largest primary. A foreshortened, perfectly round light disk is clearly visible.

Here we are inside the slanted enclosure, facing the underground portion of the slanted shaft and (what looks to be) the 0.91-meter primary concave mirror. In the lower right corner is the reverse side of the third mirror for the largest primary mirror, the 1.61-meter.

Arizona Connections

MichaelStephenWills18 Comments

A Span of 32 Years

Life for me changed September 1971 with my matriculation at the University of Arizona. The next five years (4 for a BS degree and 1 year dietetics internship) were busy with study and supporting myself leaving minimal time for travel. Then came 27 years of work and family until in my 49th year of life, with the graduation of my son, Sean, from college planned for January 2003, I anticipated having time and resources to see more of the world. The Arizona postings here flowed the outcomes of this decision that spanned the years 2003 through my Mother breaking her hip just before New Years Day 2009.

Click the links for previous Arizona postings related to the post text.

November 2003 saw our first Arizona tour. Sean was scheduled to be home from USS Observation Island. He served as an engineering officer working for Maersk contracted by the US Navy to operate the ship. We flew into Phoenix and headed north for a tour of the Mogollon Rim onto Winslow, the Painted Desert, Canyon del Chelly, Monument Valley, the Grand Canyon South Rim, the western edge of the Painted Desert north of Flagstaff to finish up at University of Arizona Homecoming.

Homecoming 2003

My 2003 homecoming schedule including a meeting with the head of the Department of Nutrition Sciences, Dr. Houtkooper. We talked of ways to re-connect with the University, leading to an invitation to serve on the College of Agriculture and Life Sciences (CALS) Alumni Board of Directors beginning November 2005. From then until November 2008 I flew to Tucson two to three times a year for planning and educational meetings: planning fund raising activities, learning how CALS benefits and connects with the people of Arizona.

These baskets from our home are reminders of my original Arizona connection and of one story of re-connection. The larger, birds, design is from my student years from a first trip to Kitt Peak. It was a gift to my parents and for decades was in their china cabinet, I’d see it each holiday visit and recall driving desert with friends, the road up the mountain, seeing the newly constructed Mayall Telescope building loom over us, the smells and views of the Sonora desert.

Meeting Native American Artists

Working for the CAL Alumni Board the first time, November 2005, I had an idea to approach Native American artists for donations of their work for student scholarships. My first outing to meet artists was to an event at the Saguaro National Monument, west of Tucson, where I met Olvera and Simon Valenzuela. They were a happy couple devoted to continuing a tradition of basket weaving. Olvera was the youngest active weaver from generations of Tohono O’odham women. Her husband, Simon, a Pascua Yaqui, learned weaving from Olvera and her family. I purchased the turtle basket, upper left, and obtained contact information.

From the bottom clockwise. Birds by Anmelia Juan of Geawuk (Kitt Peak 1972), Turtle by Olvera and Simon Valenquela (Sqguaro National Monument 2005) Stars by Simon Valenzuela for hsi daughter Pasquala Valenquela 16th Birthday (2018). Simon is of the Pascua Yaqui tribe who Learned basketmaking from his wife’s family.

I phoned them the last week of January, hoping to discuss a donation for that November. Simon answered, we talked and I learned he was in mourning for Olvera who passed away the previous week at 33 years of age, leaving her daughters Uneek and Pascuela. I did not bring up the donation and kept in touch. I felt sympathy for Simon’s situation because, twenty one years before, Sean’s mother deserted us and I raise him alone.

Olvera Valenzuela Memorial Scholarship

Over the course of months, communicating with Arizona contacts, I came to the conclusion donations by Native American artists was not a sustainable model for financing donations. The individuals were not prosperous enough and there were too few of them. Instead, during the travels documented here, I made contacts. In the Chiricahua National Monument I met Linda Kelly the owner of Triangle T Ranch who donated stays there. The Searcher had a side farrier (care of horses feet) and donated services.

With the permission of Simon and family we started the Olvera Valenzuela Memorial Scholarship. The application is an essay on the subject: “A Proposal for Native American Cultural Conservation.”  The qualified applicants are Native Americans enrolled at the University of Arizona College of Agriculture and Life Sciences (CALS) in a course of study leading to a baccalaureate. The designation “Native American” is defined for the purposes of these criteria as being a documented member of a North American tribe. It was an annual award of $500 to the successful applicant. To start I contributed $1,000 to fund it for two years.

Over the next year, Simon and I contacted potential donors, but were unsuccessful in funding the scholarship beyond two years. In the meantime, when I visited Tucson for CALS board meetings Simon and I would do outings with his daughters. Here is one from the 2006 University of Arizona Homecoming football game. This is after the game, a win for the team, with the field covered in celebrating fans.

The third basket of the photograph, a stars design, was raffled to fun Pascuala’s sixteen birthday celebration in 2018 and I won!!!!

Cheers!!

McMath-Pierce Solar Telescope – 1

The Exterior

MichaelStephenWills1 Comment

These views of the McMath–Pierce solar telescope enclosure are the preliminary to a guided tour of the instrument, April 20, 2005.

On the tower are three heliostats, plane (flat) mirrors mounted on computer-controlled platforms to follow the sun across the sky to direct sunlight to primary mirrors underground, beneath the base of the slanted shaft

Built in 1962, the building was designed by American architect Myron Goldsmith and Bangladeshi-American structural engineer Fazlur Rahman Khan. It was the largest solar telescope and the largest unobstructed aperture telescope in the world. It is named after the astronomers Robert Raynolds McMath and Keith Pierce.

Kitt Peak from below

Rocks of a complex origin

MichaelStephenWills8 Comments

“When George J. Roskruge created the official map of Pima County in 1893, he named the range after James Quinlin, who had opened a stagecoach station in the nearby town of Quinlin in 1884.” — Wikipedia article for “Quinlan Mountains.”

Kitt Peak is the highest point of the Quinlan Mountains, one of a series of ranges starting near the border with Mexico, the Baboquivari Mountains. Pan Tak pass separates Coyote Mountains from the Quinlans. Farther north there is even the Roskruge Mountains and a range named for a silver mine, the Silver Bells. Roskruge originally named “Kit’s Peak” for his sister, Phillippa, married to William F. Kitt. The peak was renamed to Kitt Peak William’s request.

Here we see a dramatic view of Quinlan Ridge with Kitt Peak observatories, taken from the access road Arizona Routh 386. The instruments I recognize are, from left to right, McMath-Pierce Solar Telescope (second in line) and, on the end, Mayall Telescope.

And more views as I progressed toward the top.

.

The dramatic peaks are hypothesized to be igneous intrusions into metamorphic rock, these are called “Sky Islands” for the environments supported on them, radically different from surrounding lowlands. Kitt Peak is known for the stands of Manzanita Bushes

Space Shuttle Prototypes, Mock-ups and other Models

a lotta high tech concrete

MichaelStephenWills6 Comments

Here are some thoughts on various physical representations of the iconic Space Shuttle we encountered during our travels.

Vision

Dr. Maxime “Max” Faget joined NASA in 1958, where he headed the group that designed America’s first manned spacecraft, the Mercury capsule. In 1969, Dr. Faget was the director of engineering and development at NASA. On April 1, 1969, Dr. Max Faget tossed this balsa wood toy toward his team of engineers hard at work landing a man on the moon. During this time Dr. Faget’s team also began creating a revolutionary space vehicle for NASA. “We’re going to build America’s next spacecraft. And it’s going to launch like a spacecraft. It’s going to land like a plane.” –text from Kennedy Space Center display, see following.

Mock-up on fire

Two Inspirations

On display next to the Shuttle Landing Facility

April 29, 2016 – Almost five years after NASA’s last space shuttle landed in Florida, an orbiter returned to the runway at the Kennedy Space Center. The model orbiter “Inspiration” was rolled out to Kennedy’s Shuttle Landing Facility on Wednesday (April 27), where it will be rebuilt into a traveling exhibit. The full-scale mockup was previously on display at the now-former location of the U.S. Astronaut Hall of Fame in Titusville. LVX System, which acquired the 122-foot-long (37 meter) shuttle replica from NASA, moved the Inspiration from the Hall to a work yard in January. The company, which has an agreement with NASA to study visual light communication for deep space missions, intends to use the space shuttle as a vehicle for both educational outreach and marketing. “Over the past four months, work has been done to bolster the shuttle’s structure and aesthetics in preparation for the move this week, an LVX spokesperson said.” – from the “Collect Space” web site

The “Inspiration” model of my photograph, from our 2018 Shuttle Landing Facility visit, is a second Space Shuttle mock-up built by Kennedy Space Center carpenters from a rocket booster body.

Happy Birthday

Mercury 7 Pre-Launch Facilities

Hosting Astronaut ZZZZZZZ’s and much more

MichaelStephenWills19 Comments

Here is the sixth in a series of photographs centered on the early history of space flight on Cape Canaveral mostly taken during a tour organized by the Cape Canaveral Lighthouse Foundation. “Google” the foundation for details of future tours. Here we explore pre-launch support for the Mercury program, including the first USA Orbital Launch of John Glenn from Launch Complexe 14 (LC 14).

Overview

Leaving LC 1 – 4 (see “Post WWII Launch Complexes”), our bus turned onto Central Control Road passing construction on Launch Complex 36 (LC36). In 2015 Blue Origin (Amazon money) leased LC36 where it planned to launch the “New Glenn” vehicle after 2020. I snapped the churned-up sand and construction equipment, not interesting at all IMHO.

Corner of Central Control and ICBM Roads. Cape Canaveral Air Force Station.

The “New Glenn” was named in homage to John Glenn, the first American to orbit the earth in 1962. We turned right onto to ICBM Road, headed generally north, following a string of launch complexes along the Altantic shore toward Launch Complex 14 (LC14). A dissapointment was not stopping to walk the Mercury 7 Memorial at the corner of ICBM Road and LC14. Our bus stopped briefly enough for the following snap. It is a memorial because John Glenn, the surviving member of Mercury 7, passed away December 8, 2016 at the age of 95.

Mercury 7 Memorial, just off ICBM Road

I will cover at length the Mercury-Atlas vehicle that powered John Glenn into orbit February 20, 1962. The tie-in between ICBM road and this series of launch complexes is the early space missions were on re-purposed Intercontinental Ballistic Missles (thus, ICBM). “Atlas” is the name of the ICBM used for Colonel Glenn’s 1962 flight. Click on the following image to find labled pushpins for the corner of Central Control and ICBM Roads (upper right), the road to LC14 and Mercury 7 Memorial.

You will also find a pushpin for the Skid Strip, bottom just to right of center. The earliest cruise missle tests (see “Cruise Missles” and “Post WWII Launch Complexes” ) included navigation to a landing on non-wheeled “skids.” The strip was maintained in support of the manned and later missions when cargo planes delivered the early space capsules, landing, not skidding hopefully, for transfer to a Pre-Launch facility, Hangar S.

Cape Canaveral Launch Complex 14 and Pre-Launch Support: Hangar S and the Skid Strip

Hangar S is seen below as we passed later in the tour. Built 1957 by the military the 61,300 square feet were acquired by NASA in 1959. The early space capsules were tested here in an vacume chamber to ensure the vehicle supported an breathable atmosphere for the occupants.

The first American space voyager was Ham, a chimpanzee. Ham lived in a residential area on the second floor of Hangar S. For a period of time the Mercury 7 shared the spartan second floor quarters. “The Right Stuff” (a 1984 film from a Tom Wolfe book) included scenes from this episode of the program.

Constructed in 1957, Hangar S served for pre-flight processing from Mercury through the final flight of the Space Shuttle. This is where the Mercury 7 astronauts were first quartered on the second floor and later, is where they stayed prior to flight. The Lunar Orbiter was prepared here.

Comfortable Quarters

In short order arrangements were made for more comfortable quarters, just off the ocean in Cocoa Beach. It was a new hotel given over entirely to the Mercury 7. Pam and I stayed there in 2018 while taking this tour, it is the La Quinta across from the International Palms. We recommend it a clean, comfortable, reasonably price and a great story to share afterwards. The Atlantic Ocean is a five minute walk.

La Quinta Inn was the home of the Mercury 7 Astronauts, 1275 N Atlantic Avenue Cocoa Beach, Florida 32931

I learned from the tour how the hotel was donated to the Mercury 7 by a private individual. They owned the hotel. Here is a very informative sign just off the La Quinta lobby with their names. Each first mission, as named by the astronaut, is listed.

Shuttle Landing Facility

a lotta high tech concrete

MichaelStephenWills3 Comments

We left our Cocoa Beach hotel in the pre-dawn hours of February 6, 2018, with our tickets in hand for the first launch of Space X’s “Falcon Heavy”, our reward for arriving early was a spot on the third bus.

Tooling Around

On the way to our final destination, the Apollo-Saturn V center, we were privileged to visit the Shuttle Landing Facility. Here are a few snapshots from the bus.

Two buses ahead of us

Aside from holding the record for world’s longest runway, the surface itself exceptionally engineered, consisting of an extremely high-friction concrete strip designed to maximize the braking ability of the Space Shuttle at its high landing speed, with a paving thickness of 16.0 inches (40.6 cm) at the center. It uses a grooved design to provide drainage and further increase the coefficient of friction. The original groove design was found to actually provide too much friction for the rubber used in the Shuttle’s tires, causing failures during several landings. This issue was resolved by grinding down the pavement, reducing the depth of the grooves significantly

Bald Eagle Nest

Painful Memories

MichaelStephenWills1 Comment

Our Shuttle Landing Facility side trip brought us twice by one of the five Bald Eagle nests around Kennedy Space Center. The entire Center land is part of the National Wildlife Refuge of Merrit Island. Rockets and wildlife coexist very well, in fact the Shuttle Landing Facility is also known as the Gator Tanning Facility. The reptiles crawl up from the canals surrounding the landing strip on all four sides to bask on the smooth concrete.

First Turn

The nest tree is on the median of a divided highway. Driving into the Landing Facility the nest tree was to the east, brightly lit by the morning sun.

Second Turn

On the return trip the nest was backlit. Look closely: the head of an eaglet (?) is just visible above the nest rim.

The parent eagle is silhouetted in the tree branches.

Columbia STS-107

Painful Memories

MichaelStephenWills

We left our Cocoa Beach hotel in the pre-dawn hours of February 6, 2018 with our tickets in hand for the first launch of Space X’s “Falcon Heavy, our reward for arriving early was a spot on the third bus to the Apollo-Saturn V center. At 4 miles from Launch Complex 39a this is the prime location for “VIP” viewing.

The Columbia Disaster

We were privileged to visit the Shuttle Landing Facility on the way, this hangar on the SLF access road was pointed out by the guide. Here was where the remains of Space Shuttle Columbia were collected after the disaster.

Click Any Image for a larger viewe

STS-107 was the 113th flight of the Space Shuttle program, and the 28th and final flight of Space Shuttle Columbia. The mission launched from Kennedy Space Center in Florida on January 16, 2003 and during its 15 days, 22 hours, 20 minutes, 32 seconds in orbit conducted a multitude of international scientific experiments. It was also the 88th post-Challenger disaster mission. An in-flight break up during reentry into the atmosphere on February 1 killed all seven crew members and disintegrated Columbia. — wikipedia

The logo is from the Columbia Accident Safety Board, the group that investigated the cause of the loss.

Immediately after the disaster, NASA convened the Columbia accident Investigation Board to determine the cause of the disintegration. The source of the failure was determined to have been caused by a piece of foam that broke off during launch and damaged the thermal protection system (reinforced carbon-carbon panels and thermal protection tiles) on the leading edge of the orbiter’s left wing. During re-entry the damaged wing slowly overheated and came apart, eventually leading to loss of control and disintegration of the vehicle. The cockpit window frame is now exhibited in a memorial inside the Space Shuttle Atlantis Pavilion at the Kennedy Space Center. — wikipedia

I zoomed in for a close look at the interior

The damage to the thermal protection system on the wing was similar to that Atlantis had sustained in 1988 during STS-27, the second mission after the Space Shuttle Challenger disaster. However, the damage on STS-27 occurred at a spot that had more robust metal (a thin steel plate near the landing gear), and that mission survived the re-entry. — wikipedia

When is “moss” not moss?

Southern Gothic

MichaelStephenWills

We spotted this stuff within minutes of arriving at McKee Gardens for an afternoon visit with the grandchildren. Festooned above our heads from thick Oak branches, I could not resist pulling out the camera for this photograph to capture the flavor of Southern Gothic. Fortunately, our group included neither deeply flawed nor disturbing characters, though we can confess to a touch of eccentricity.

Above the Cafe tables

Spanish Moss produces inconspicuous flowers with tiny seeds. Spanish Moss also propagates from fragments of the fine leaves.

Spanish Moss is neither moss nor Spanish. Scientific name Tillandsia usneoides, this flowering plant is in the family Bromeliaceae that includes pineapple. Here we have two epiphytic bromelias sharing the trunk of a palm.

Spanish Moss with other Bromeliads

A rootless epiphyte native to the tropical / semi-tropical Americas, Spanish Moss has a preference for southern live oak (Quercus virginiana) and bald cypress (Taxodium distichum) because of their high rates of foliar mineral leaching (calcium, magnesium, potassium, and phosphorus) that provides an abundant supply of nutrients to the epiphytic plant.

Spanish Moss on Palms
Spanish Moss on Southern Live Oak

My two volume “go to” resource for plants and trees had sparse information about Spanish Moss and no wonder as it is a burden on trees, though not parasitic, and so more a pest than a decorative element to cherish. Surprisingly, Spanish Moss was purposely introduced to Hawaii where it is now known as “Pele’s Hair” after their fire goddess.
