Electra EL-2 Goldfinch
The Electra EL-2 Goldfinch is a technology demonstrator developed by American startup Electra.aero. The EL-2 is a hybrid electric aircraft with distributed propulsion for short takeoff and landing (STOL). Development Electra creator John Langford founded Aurora Flight Sciences in 1989, sold to Boeing in 2017. The first test flight happened on November 11, 2023, all-electric powered, from Manassas Regional Airport in Virginia. On November 17, it flew again for 23 minutes, powered by its hybrid-electric drivetrain, reaching . Electra.aero wants to develop a nine passenger-aircraft (or of cargo) capable of operating from an area soccer field-sized with a ground roll, for a range. The company aims to fly a full-scale prototype in 2026, then a certification test aircraft targeted for a 2028 introduction. By late April 2024, the demonstrator had flown for over 10 hours and had achieved landings and takeoffs. Its longest flight exceeded 1.5 hrs, its highest altitude reached was , ...

Estes Industries
Estes Industries is a model rocket company that was started in Denver, Colorado, USA. History Estes Industries was founded by Vernon Estes in 1958; in 1961, the company moved to a 77-acre tract of land on the outskirts of Penrose, Colorado. In 1969, Vernon sold the company to the Damon Corporation of Needham, Massachusetts, a company which also purchased a number of other hobby companies including a smaller competitor of Estes, Centuri Engineering of Phoenix, Arizona. Damon merged the two companies under the name Centuri Engineering. The Penrose entity continued doing business as Estes Industries. Centuri Engineering model rocket products continued to be developed, marketed and sold from the Centuri offices in Phoenix as well, although the actual manufacturing of Centuri products was soon moved to the Estes facility in Penrose. Sales of Centuri model rocket products were never as successful as Estes brand products and the Centuri Engineering offices in Phoenix were finall ...

Climate Change Research
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. The existence of the greenhouse effect, while not named as such, was proposed as early as 1824 by Joseph Fourier. The argument and the evidence were further strengthened by Claude Pouillet in 1827 and 1838. In 1856 Eunice Newton Foote demonstrated that the warming effect of the sun is greater for air with water vapour than for dry air, and the effect is even greater with carbon dioxide. John Tyndall was the first to measure the infrared absorption and emission of various gases and vapors. From 1859 onwards, he showed that the effect was due to a very small proportion of the atmosphere, with the main gases having no effect, ...

MIT Daedalus
The Massachusetts Institute of Technology, MIT Aeronautics and Astronautics Department's Daedalus is a class of three human-powered aircraftJohn McIntyreMan's Greatest Flight, ''AeroModeller'', August 1988 (in files of Royal Aeronautical Society Human Powered Aircraft Group) (accessed Nov. 13 2012) that included ''Daedalus 88''which, on 23 April 1988, flew a distance of in 3 hours, 54 minutes, from Heraklion on the island of Crete to the island of Santorini. The flight holds official Fédération Aéronautique Internationale, FAI world records for total distance, straight-line distance, and duration for human-powered fixed-wing aircraft. The class was named after the mythological inventor of aviation, Daedalus, and was inspired by the Greek myth of Daedalus' escape from Crete using manmade wings. The three aircraft in the class are: * ''Light Eagle'' (originally ''Michelob Light Eagle''): a prototype. * ''Daedalus 87'': Crashed during testing at Rogers Dry Lake (NASA Dryden F ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Drone Warfare; 2024. e-ISBN (PDF) 978-3-11-074203-9.H. Pan; M. Zahmatkesh; F. Rekabi-Bana; F. Arvin; J. HuT-STAR: Time-Optimal Swarm Trajectory Planning for Quadrotor Unmanned Aerial Vehicles IEEE Transactions on Intelligent Transportation Systems, 2025. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage,F. Rekabi-Bana; Hu, J.; T.

Astronautics
Astronautics (or cosmonautics) is the practice of sending spacecraft beyond atmosphere of Earth, Earth's atmosphere into outer space. Spaceflight is one of its main applications and space science is its overarching field. The term ''astronautics'' (originally ''astronautique'' in French language, French) was coined in the 1920s by J.-H. Rosny aîné, J.-H. Rosny, president of the Académie Goncourt, Goncourt academy, in analogy with aeronautics. Because there is a degree of technical overlap between the two fields, the term aerospace is often used to describe both at once. In 1930, Robert Esnault-Pelterie published the first book on the new research field. The term ''cosmonautics'' (originally ''cosmonautique'' in French) was introduced in the 1930s by Ary Abramovich Sternfeld, Ary Sternfeld with his book ''Initiation à la Cosmonautique'' (Introduction to cosmonautics) (the book brought him the Robert Esnault-Pelterie#Prix REP-Hirsch, Prix REP-Hirsch, later known as the Prix d'As ...
