Confirmation of loss of contact with Voyager 2, currently approximately 21 billion kilometers from Earth. On July 21, commands sent from Earth to Voyager 2 accidentally caused Voyager’s High Gain Antenna to point 2 degrees away from Earth. Therefore Voyager cannot currently receive messages from Earth or send messages in the direction of Earth. A…
A rare disease that affects only one in a million people worldwide and has yet to be treated. Some may think that sleeping is not a good arrangement… But wrong…. Most people diagnosed with this disease sometimes develop temporary brain damage After waking up, they don’t remember anything. Getting up during sleep to go to…
is an embodied approach to Artificial Intelligence (AI) in which robots are automatically designed using Darwinian principles of natural selection. The design of a robot, or a subsystem of a robot such as a neural controller, is optimized against a behavioral goal (e.g. run as fast as possible). Usually, designs are evaluated in simulations as…
Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent 75 hours on the moon in December 1972. They landed in the Taurus-Littrow valley of the moon Fellow traveler Ronald Evans was traveling around the moon at that time. Schmitt photographed Eugene Cernan standing next to the American flag and the umbrella-shaped high-gain antenna of their…
The Manhattan Project nicknamed the Trinity Test was the most top secret nuclear test conducted by the United States. The movie Oppenheimer was released about it.Only a handful of people knew about it…after the test America dropped the nuclear bomb on Japan. But after this trinity test there was another group in this world who…
The first exoplanet we discovered in transit was OGLE-56-b, discovered in 2002. Located 5,000 light-years away from its parent star, this hot Jupiter (because it is a gas giant like Jupiter) is larger than our own Jupiter. Iron precipitation is thought to occur here at a temperature of 1726 degrees Celsius that creates affinity for…
His oxygen pack contains breathing air for seven and a half hours His space suit will have liters of water to quench his thirst The jet pack will carry 5 pounds of fuel to fly back to his parent spacecraft He would have died and drifted off into space unless someone else had already rescued…
This image was taken as part of the JWST Advanced Deep Extragalactic Survey (JADES) — one of Webb’s largest first year science programs. Though data is still coming in, JADES is already revolutionizing what we know about galaxies and star formation in the early universe. Light from distant galaxies is stretched to longer wavelengths and…
A vapor cone can be seen when going from supersonic to subsonic speed. Along with that, local residents also experience Sonic Boom. The course is controlled by moving the Grid Fins on top of the Booster to control the flow of air. Extend the landing legs only just before landing to avoid affecting aerodynamics. The…
