Voyager 1 reaches Jupiter (1979)

posted Wednesday, 5 March 2014 00:00

The Voyager 1 space probe made its closest approach to Jupiter on 5 March 1979. The image below was taken on 5 February 1979 when Voyager 1 was still 28.4 million kilometers (17.5 million miles) away. The volcanic moon Io is in front of Jupiter just right of center on this image, ice and water covered Europa is visible to the right, and totally ice covered Callisto can be seen near the bottom.

nighttime launch of Pioneer 10

On 2 March 1972, NASA launched Pioneer 10 from Cape Canaveral. Pioneer 10 was the first spacecraft to travel through the asteroid belt, the first spacecraft to make direct observations of Jupiter, and the first man-made object to travel on a flight path out of the solar system into interstellar space. Until February 1998 when it was passed by Voyager 1, Pioneer 10 was the most remote object ever made by humans.

Apollo 1 Disaster (1967)

posted Monday, 27 January 2014 00:01

27 January 1967: Astronauts Gus Grissom, Ed White, and Roger Chaffee died in the Apollo 1 command module during testing after a fire started. The command module was pressured with pure oxygen to 2 atmospheres making it an obvious fire hazard. Since the door was designed to open inward and the interior pressure was 1 atmosphere greater than the exterior, the door was held firmly shut. Toxic smoke asphyxiated the astronauts and the intense oxygen-fueled flames roasted them.

Thomas Edison receives patent for light bulb (1880)

posted Monday, 27 January 2014 00:00

Thomas Edison received US Patent 223,898 for the "Electric Lamp" on this day in 1880.

Edison’s device is an incandescent light source — an object so hot that it emits visible light. It also emits copious amounts of infrared (often called "heat rays"). Only 10% of the electric energy put into an Edison-style "Electric Lamp" comes out as useful illumination. The rest is invisible, wasteful heat.

The traditional light bulb is destined to fade away in popularity as newer, more efficient technologies take over. What will we use as the icon for a brilliant idea in the future?
