“NASA's Pathfinder, Pathfinder Plus, Centurion and Helios Prototype were an evolutionary series of solar- and fuel-cell-system-powered unmanned aerial vehicles. AeroVironment, Inc. developed the vehicles under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program. They were built to develop the technologies that would allow long-term, high-altitude aircraft to serve as “atmospheric satellites”, to perform atmospheric research tasks as well as serve as communications platforms”. – Wikipedia

The 18-hour flight was a functional checkout of the aircraft's systems and performance in preparation for an attempt to reach sustained flight at 100,000 feet altitude later in the summer.

“A cuddle party or cuddle puddle is an event designed with the intention of allowing people to experience non-sexual group physical intimacy through cuddling. Cuddle parties are described by organizers as “workshop/social-events” that gives adults an opportunity to “give and receive welcomed affectionate touch in a no-expectation, friendly setting, according to your needs, desires, interests, and boundaries”. Cuddle parties are described as non-sexual events but kissing may occur at some parties”. – Wikipedia

“Mehndi or menhdi is the application of henna as a temporary form of skin decoration in India, as well as by expatriate communities from the country. The word mehndi is derived from the Sanskrit word mendhikā. The use of mehndi and turmeric is described in the earliest Vedic ritual books. Haldi (Staining oneself with turmeric paste) as well as mehndi are important Vedic customs as a symbolic representation of the Outer and the Inner Sun. Vedic customs are meant to awaken the “inner light” and so the gold of the inner Sun has an important symbolic function”. – Wikipedia

Demonstrators take part in a mass “face-sitting protest” outside the Houses of Parliament in central London on December 12, 2014, as they protest against changes to p*rnography regulations. An amendment to the 2003 Communities Act applies the same strict rules to p*rn bought online as those included in the guidelines set out by the British Board of Film Censors for DVDs. The new laws ban films that feature s*x acts, such as spanking, caning, strangulation, aggressive whipping, humiliation, and face-sitting. Ministers say the rules have been brought in to protect s*x workers. But campaigners say it is an attempt to censor and control the internet. Paid-for videos shot overseas and viewed online in the UK are not affected by the new rules, which were introduced on December 2, 2014. (Photo by Leon Neal/AFP Photo)

The Haʻikū Stairs, also known as the Stairway to Heaven or Haʻikū Ladder, is a steep hiking trail on the island of Oʻahu. The trail began as a wooden ladder spiked to the cliff on the south side of the Haʻikū Valley. It was installed in 1942 to enable antenna cables to be strung from one side of the cliffs above Haʻikū Valley to the other. A building to provide a continuous communication link between Wahiawā and Haʻikū Valley Naval Radio Station was constructed at the peak of Puʻukeahiakahoe, elevation about 2,800 feet (850 m). The antennae transmitted very low frequency radio signals from a 200,000-watt Alexanderson alternator in the center of Haʻikū valley. The signals could reach US Navy submarines as far away as Tokyo Bay while the submarines were submerged.

“The Miss Exotic World Pageant (officially, the Miss Exotic World Pageant and Striptease Reunion) is an annual neo-burlesque pageant and convention, and is the annual showcase event (and fundraiser for) the Burlesque Hall of Fame (formerly the Exotic World burlesque museum). The pageant, sometimes referred to as the “Miss America of Burlesque”, attracts former burlesque queens from past decades, as well as current participants of the neo-burlesque scene. The pageant consists of burlesque performances spanning a weekend, culminating with the competition to crown a single performer as Miss Exotic World. Because of the significance of the Exotic World Burlesque Museum to the burlesque community, winning the pageant is considered a top honor for a burlesque performer”. – Wikipedia
