Our results can also be used for semispherical meteoroid particles of the interplanetary dust entering the Earth's atmosphere. We determined thetime, velocity, and angle of impact as functions of the launch height, direction,speed, and size of spherical re-entry particles.

To partly fill thisgap, we performed computer modeling with which we studied the dynamics of spherical re-entry particles falling to Earth due to air drag.

Since it is very difficult to measure thesephysical parameters, almost nothing is known about them. Smaller space debris fragmentsburn up and evaporate in the atmosphere, but larger ones fall to Earth's surface.For practical reasons, it would be important to know the mass, composition,shape, velocity, direction of motion, and impact time of space debris re-enteringthe atmosphere and falling to Earth. With current technology, spacedebris smaller than 10 cm cannot be tracked. The low-Earth orbits (at heights smaller than 2,000 km) and orbits nearthe geostationary-Earth orbit (at 35,786 km height) are especially endangeredbecause most satellites orbit at these latitudes.

To date, the Earthtime 1.26 sculpture has been installed in 15 cities on 4 continents: Denver, Colorado (2010), Sydney, Australia (2011), Amsterdam, Netherlands (2013), Singapore (2014), Montreal, Canada (2015, 2016, 2017), Prague, Czech Republic (2015), Durham, UK (2015), Santiago, Chile (2016), Shanghai, China (2017), Chiayi, Taiwan (2018), Hong Kong, China (2018), Geneva, Switzerland (2020), Munich, Germany (2021), Jeddah, Saudi Arabia (2021), and Milan, Italy (2022). Connecting the past with the present, the artwork takes ancient methods to a new urban scale. These custom-colored twines are knotted both by loom and by hand, and every rope is spliced using centuries-old craft techniques. Sculpture fabrication begins with braiding custom engineered fibers which are fifteen times stronger than steel by weight. The number in the title refers to a measurement of time, as the earth’s day was shortened by 1.26 microseconds.
Inside Echelman’s studio, the physical form of Earthtime 1.26 Jeddah was digitally modeled with inspiration from a scientific data set describing a single geological occurrence - an earthquake and tsunami in Chile in 2010 - which caused ripple effects around the globe and even sped up the earth's daily rotation. Carnegie Mellon University 132K subscribers Carnegie Mellon University has developed EarthTime, a tool that turns huge datasets into interactive visualizations, allowing users to see the effects. These include architects, designers, and model-makers in the studio, as well as an external team of aeronautical and structural engineers, computer scientists, lighting designers, landscape architects, and a fabrication team.
To create the sculptural form, Echelman works with teams both inside and outside her studio. Each time a single knot moves in the wind, the location of every other knot in the sculpture’s surface is changed in an ever unfolding dance of human-made creation with the forces of nature beyond our control. Each installation has unique colored lighting designed to speak with. To date, the Earthtime 1.78 sculpture has been installed in Madrid, Spain (2018), Dubai, UAE (2018), Beverly Hills, CA (2019), Bors, Sweden (2021), Helsinki, Finland (2021), Vienna, Austria (2021), and Milan, Italy (2022).
EARTHTIME CHAPTER 1 VIDEO SERIES
The sculpture serves as a symbol of interconnectedness, composed of countless intertwined fibers. The Earthtime series is a global traveling project. Janet Echelman's Earthtime sculpture series heightens our awareness of our interconnectedness with one another and our physical planet.Įarthtime 1.26 Jeddah was installed on the new Art Promenade along the Jeddah waterfront Corniche Between December 2021 and April 2022 as part of a new ambitious creative project by the cultural producer and art collector Swizz Beatz.
