This afternoon’s sky was overcast, perfect for photographing wildflowers: clouds thin enough for light to pour through. In the clouds’ shadow there is not enough light for the plant to cast its own distracting shadows. Compare an earlier trillium photograph (click me to go there).
For the following photograph is a study in habitat. At f32, focusing on the trillium, the surroundings are clearly identifiable: several budding Foam Flower heads (Scientific Name: Tiarella), fern, rotting wood, the forest floor hidden by leaf clutter.
I released the shutter (with a 2 second delay) during a break in spring breezes, the overcast lighting bright enough for a speedy 1/8 second exposure. The focus on the opening trillium bloom is just as crisp in this exposure as the next.

At 4 f-stop, the entire plant is in focus while many habitat elements are a soft blur. An interesting point is the leaf on the left. It is in focus somewhat and is a distraction. This was an issue, in my opinion, for the first photograph.
Discover the hidden world of Phragmites australis, the common reed: a story of resilience, beauty, and ecological significance, told through the eyes of the wetlands.
On the southern shore of Cayuga Lake, where waters mirror the ever-changing sky, I found this common reed, Phragmites australis, a plant of unassuming grace yet profound influence. This tale unfolds at the broad boarders of earth and water, a refuge and kingdom to countless beings.
Phragmites australis, a reed both simple and complex, begins its journey as a whisper in the mud. From the soft, fertile earth, it bursts forth into the world, a slender shoot reaching for the heavens. Its growth is steady and assured, fueled by the sun’s embrace and the water’s caress. In time, it stands tall, a sentinel in a sea of green, its feathery plumes, called panicles, wafted by the breeze.
This reed, you see, is a cornerstone of its ecosystem, a master architect, shaping its environment, crafting homes and havens for creatures great and small, in keeping with the genus name “Phragmites.” The Greek word “phragma” translates to “fence” or “hedge”, derived from the verb “phrassein”, meaning “to enclose.” Within that realm tiny creatures find refuge. From dragonflies and damselflies to grasshoppers and beetles are found by careful, patient observers. Insects play essential roles in pollination and nutrient cycling. Birds use the dense vegetation for shelter and foraging, you might find red-winged blackbirds, marsh wrens, and rails among the stems. Frogs, toads, and salamanders find refuge in reedy marshes. They lay their eggs in the waterlogged areas, and their tadpoles thrive amidst the reed stems. Phragmites australis is a giver of life, a source of sustenance and protection for many.
Yet, the tale of Phragmites is also one of struggle and resilience. In lands far from its native soil, it is often seen as an invader, a usurper of territories, spreading with a zeal that can overwhelm native flora and alter habitats. Its spread, unchecked, can lead to monocultures, diminishing biodiversity. But in its essence, Phragmites does not seek conquest but survival, thriving in spaces both gentle and harsh, adapting with an elegance that commands admiration.
As seasons turn, the reed undergoes a transformation, its green turning to gold, then to the brown of the earth from which it sprang. But even in decay, it nurtures life, its fallen stalks a shelter for the small and the silent, its seeds a promise of renewal. And when spring whispers anew, Phragmites rises once more, a cycle unbroken, a circle complete.
In the tale of Phragmites australis, we find a narrative of life itself—growth and decay, beauty and conflict, resilience and adaptation. This common reed, standing tall among the waters of the world, is a testament to the enduring power of nature, a reminder of the intricate tapestries of life that flourish in the quiet corners of our planet.

Let’s delve into the history these buoys are part of. You, as a curious observer, are witnessing a fragment of a narrative that stretches back over a century. These navigational buoys are descendants of the earliest markers that adorned the inland waters of New York State and the Erie Canal, of which Cayuga Lake is an integral part.
The Erie Canal and Cayuga’s Connection
The Erie Canal, an engineering marvel of the 19th century, opened in 1825, transforming New York and the entire Great Lakes region. It was the superhighway of its time, connecting the Atlantic Ocean to the Great Lakes, and thereby shaping the course of economic and social history in the United States. Cayuga Lake, connected to this system via the Cayuga-Seneca Canal, was part of this vast network of navigable waters.
Navigation Buoys: Beacons of Progress
As commerce flourished, so too did the need for reliable navigation. The buoys, then as now, served as critical signposts, ensuring that vessels could traverse these waterways safely. Imagine the countless boats that relied on these markers – from the large freighters carrying goods to the smaller craft bearing passengers – each buoy a sentinel ensuring their safe passage.
Modern Sentinels
Today, the navigation buoys on Cayuga Lake and other inland waters continue this legacy. They are the modern sentinels of the deep, equipped with the latest technology to guide the way. Just as the Erie Canal once heralded a new era of travel and trade, these buoys now symbolize the enduring importance of safe and efficient water transportation.
The Future of Inland Navigation
As you reflect upon the photograph, consider the ongoing narrative of these buoys and the waterways they mark. In a world increasingly concerned with sustainable modes of transportation, the historical importance of these channels resurfaces. The waterways that once fueled the expansion of a nation may once again play a pivotal role, this time in the quest for greener alternatives to overland routes.

Step behind the scenes of space exploration with this dive into the awe-inspiring details of the Space Shuttle Atlantis, its thermal-protected wings to the onboard engines.
Imagine, if you will, stepping onto the grounds of NASA, where the air buzzes with the legacy of space exploration and the spirit of human achievement. It’s a place where dreams of the cosmos turn into reality. Our 2017 Launch Director tour not only brought us face-to-face with the marvels of space travel but allowed me to delve into the intricate details of one of NASA’s most iconic spacecraft: the Space Shuttle Atlantis. In this episode 6 of our adventure, we continue exploring the engineering marvel that is Atlantis, focusing on its wings, rear stabilizer, and onboard engines—elements critical to its legendary missions.
Atlantis delta shaped wings
The Space Shuttle Atlantis, a name synonymous with discovery and exploration, represents a pinnacle of human ingenuity. As you walk around the Atlantis exhibit, you can’t help but be awed by the shuttle’s design, particularly its wings. The wings of Atlantis, with a wingspan of about 78 feet, are not just structures of metal and composite materials; they are the shuttle’s lifeline during re-entry into Earth’s atmosphere. These delta-shaped wings are designed to withstand the scorching temperatures of re-entry, allowing Atlantis to glide back to Earth with grace and precision. The material covering the wings, known as the Thermal Protection System (TPS), consists of thousands of heat-resistant tiles and reinforced carbon-carbon panels, safeguarding the shuttle and its crew from temperatures exceeding 1,650 degrees Celsius.
Atlantis Stabilizer
As your gaze shifts towards the rear of Atlantis, the vertical tail fin, or the rear stabilizer, commands attention. Standing about 17 feet tall, this stabilizer is more than just a rudder; it’s a critical component for maintaining the shuttle’s stability during the different phases of its mission. During the launch, it helps keep the shuttle on course as it ascends through the atmosphere. In space, it plays a minimal role, but upon re-entry, it becomes vital again, ensuring the shuttle remains stable and oriented correctly as it descends through the atmosphere, allowing for a safe landing.
Atlantis Onboard Engines
In this exploration of Atlantis, after the wings and stabilizer, we encounter the heart of the shuttle’s propulsion system: its onboard engines. The Space Shuttle Main Engines (SSMEs), three in total, are marvels of engineering, capable of producing a combined thrust of over 1.2 million pounds. These liquid-fueled engines play a crucial role in propelling the shuttle from the launch pad into orbit. What’s fascinating is their ability to throttle up or down depending on the phase of the launch, providing the precise amount of power needed at any given moment. The engines are fed by the External Tank, the only part of the shuttle not reused, which carries the liquid hydrogen and liquid oxygen needed for combustion. Upon reaching orbit, the Orbital Maneuvering System (OMS) engines take over, allowing Atlantis to navigate the vacuum of space with finesse, adjusting its orbit and facilitating the meticulous maneuvers required for satellite deployment or docking with the International Space Station.
Walking away from the Atlantis exhibit, what stays with you is not just the sight of this magnificent spacecraft but an appreciation for the ingenuity and dedication that went into its design. Every wing, every tile on the stabilizer, and every roar from the engines tell a story of human curiosity, the drive to explore beyond our confines, and the relentless pursuit of knowledge. The Space Shuttle Atlantis is more than a machine; it’s a symbol of what humanity can achieve when we dare to dream big and work tirelessly towards those dreams. So, as you look up at the night sky, remember the wings that carried our dreams, the stabilizer that kept us on course, and the engines that propelled us into the unknown, reminding us that the final frontier is not so final after all.

The Canadarm, or Canadarm1, officially known as the Shuttle Remote Manipulator System (SRMS) and sometimes referred to as the SSRMS, represents a series of robotic arms utilized aboard the Space Shuttle orbiters. These arms were instrumental in deploying, manipulating, and retrieving payloads. Following the tragic Space Shuttle Columbia disaster, the use of Canadarm became invariably linked with the Orbiter Boom Sensor System (OBSS). The OBSS played a crucial role in examining the shuttle’s exterior for any damages to its thermal protection system, enhancing the safety of subsequent missions.
The genesis of Canada’s involvement in the Space Shuttle program dates back to 1969 when the National Aeronautics and Space Administration (NASA) extended an invitation to Canada. At the outset, the specifics of Canada’s role were unclear, though the need for a manipulator system was immediately recognized as vital. The Canadian firm DSMA ATCON had previously made strides in robotics with the development of a robot designed to load fuel into CANDU nuclear reactors, capturing NASA’s interest. By 1975, a formal agreement was reached between NASA and the Canadian National Research Council (NRC), under which Canada would undertake the development and construction of the Canadarm.
The NRC subsequently awarded the contract for the manipulator to Spar Aerospace (currently known as MDA), under which three distinct systems were to be developed: an engineering model to aid in design and testing, a qualification model for environmental testing to ensure the design’s suitability for space, and a flight unit destined for use in missions. This collaborative effort marked a significant milestone in the use of robotics in space exploration, showcasing international cooperation in advancing space technology.

With the thermometer in the 60’s on March 10, 2020 the “buttercups” of yesterday are open. When we first moved here, the plants were much thinner. I used fertilizer spikes on the Magnolia tree around which they grow. Each early the flowers pollinate, forming seeds and spreading.
A tripod held the composition steady, and the timer was set to 2 seconds for extra stability at the f25 setting.
Here is a slideshow of yesterday and today’s shots.

In February 2020, I captured images of the first flowers to bloom on their property with a Canon 5D Mark IV DSLR and a macro lens. The flowers belong to the Eranthis genus, known for early flowering.
These flowers are the first to bloom on our property, around the magnolia tree, and are also the first wildflowers photographed with my then new Canon 5D Mark IV dslr . Each year these “buttercups” grow thicker and spread. The latin scientific name Eranthis hyemalis proclaims the early nature of its flowering both in the genus, “Eranthis” – composed of two Greek language roots meaning “spring flower”, and species, “hyemalis” – a term from the Latin language meaning, “winter flowering.” The genus encompasses eight species, all early flowering plants with the common name winter aconite. These can also rightly be called Buttercups as the plant belongs to family Ranunculaceae, buttercups.
To capture the intricate details possible with the Canon EF 100 mm f/2.8 Macro lens I used here, it’s often necessary to adjust the camera settings to allow for a longer exposure time. This adjustment ensures that enough light reaches the sensor, particularly in macro photography or low-light situations, which helps in producing sharper and more detailed images. All these photographs are from f25. Setting a longer exposure compensates for the reduced light that might be a consequence of using a smaller aperture (higher f-number) for greater depth of field, a common technique in macro photography.”
It’s important to note that while setting a longer exposure can improve image quality by allowing more light to hit the camera’s sensor, it can also introduce the risk of motion blur if the camera or subject moves during the exposure. To minimize camera shake and achieve the best results, I used a Manfrotto “BeFree” tripod and the camera’s built-in timer set to a 2 second delay after a manual shutter release.
With the thermometer hovering above freezing, these blooms did not open today. The calendar says “late winter”, these Aconite are singing “early spring.”

Step beyond Earth’s bounds and glimpse the astounding intricacies of the Space Shuttle’s journey. Discover the engineering marvels that propelled humanity into orbit and back, navigating the cosmos with precision. Unveil the secrets of the stars now.
The Space Shuttle, officially known as the Space Transportation System (STS), was an iconic spacecraft operated by NASA from 1981 to 2011. It consisted of an orbiter with wings for landing like an airplane, external fuel tanks, and solid rocket boosters. With its multiple missions ranging from satellite deployment to the construction of the International Space Station, the Space Shuttle was a symbol of human ingenuity in space exploration. Central to the Shuttle’s success was its navigational system, which combined state-of-the-art technology of its time with human expertise.
The navigation of the Space Shuttle was a complex orchestration involving both internal and external elements designed to work in the harsh environment of space. The photographs attached illustrate some of the external navigational elements.
External Navigational Elements
The external surface of the Space Shuttle, as seen in the following images, was covered with thousands of thermal protection system tiles. These tiles were crucial not only for protecting the Shuttle from the extreme temperatures experienced during re-entry into Earth’s atmosphere but also housed the critical sensors for navigation.
Reaction Control System (RCS)
One of the key external navigational features was the Reaction Control System (RCS), seen as clusters of small circular ports below the cockpit windows. The RCS was composed of small thrusters that could fire in short bursts to adjust the Shuttle’s orientation or speed in space. This system was vital during the maneuvers in orbit, such as satellite deployment, docking with the International Space Station, and repositioning for re-entry into Earth’s atmosphere.
Internal Navigational Elements
Internally, the Space Shuttle featured a complex avionics system. The following image depicts part of the orbiter’s internal structure with an array of docking mechanisms and sensor housings. The round port, surrounded by a ring of bolts, is likely an interface for the Orbiter Docking System, used for rendezvous and docking with the International Space Station.
The following image shows a close-up of one of the orbiter’s windows, surrounded by reinforced panels. Each window was crucial for manual navigation, allowing astronauts to visually confirm their orientation and position relative to celestial objects and the Earth. The windows were also essential during landing, which was conducted manually by the Shuttle’s commander.
Navigational Avionics
The Shuttle’s navigation was supported by an avionics system that included inertial measurement units (IMUs), star trackers, and various other sensors. IMUs tracked the Shuttle’s position by measuring its velocity and direction, while star trackers used sightings of known star patterns to calibrate the Shuttle’s orientation in the vastness of space.
The navigational computers onboard processed data from these systems to maintain the trajectory and manage the Shuttle’s multiple systems. The computers were capable of autonomous operation, although astronauts were trained to take over manually if necessary.
Ground Support and Telemetry
In addition to onboard systems, navigation relied heavily on ground-based tracking and data relay satellites. The Shuttle communicated with NASA’s Mission Control Center, which monitored its position and trajectory, providing updates and corrections as needed. Telemetry data sent back to Earth included velocity, altitude, and engine performance metrics, which were crucial for ensuring the Shuttle’s safe passage in and out of orbit.
In Summary
The Space Shuttle’s navigational capabilities were a testament to the integration of technology and human skill. From the RCS ports on its tiled exterior to the sophisticated avionics inside, every component played a critical role in the Shuttle’s missions. This harmonious blend of internal mechanisms and external sensors, complemented by vigilant ground support, enabled the Space Shuttle to navigate the cosmos and return safely home, mission after mission.
