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.
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.
Voyager 1 passed Pioneer 10 on 17 February 1998 to become the most distant human-made object in space. Voyager 1 is currently 113 times further from the sun than the earth (113 astronomical units) followed by Pioneer 10 at 100 AU, Voyager 2 at 91 AU, and Pioneer 11 at 80 AU.
Columbus and crew arrived at the Portuguese controlled Azores Islands 15 February 1493 on the return leg of his first American voyage. This was the first land they had seen since leaving America 30 days earlier. They would arrive at their home port of Palos de la Frontera, Spain on 15 March 1493.

Batty: Why are you staring at us Sebastian?
Sebastian: Because. You’re so different. You’re so perfect.
Sebastian: What generation are you?
Batty: Nexus 6.
Sebastian: Ah, I knew it. Because I do genetic design work for the Tyrell Corporation. There’s some of me in you.
31 January 1958: Explorer 1 became the first artificial satellite launched into space by the United States. Onboard was a cosmic ray detector designed to measure the radiation environment in Earth orbit. Explorer I subsequently discovered the Van Allen Radiation Belts.
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.

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?
Voyager 2 made its closest approach to Uranus on 24 January 1986. It is the only space probe to have visited this planet so far. Voyager 2 is one of five space probes currently on a solar system escape trajectory.
