Space shuttle Endeavour on mission STS-130 delivered Tranquility Node 3 (the final connecting node) and the Cupola (a seven-windowed robotics control room ) to the International Space Station (ISS). These were the last modules contributed by the US to the ISS. The first ISS module (Zarya — Russian for dawn) was launched by a Proton rocket from Baikonur Cosmodrome in Kazakhstan on 20 November 1998. Additional modules are scheduled until 2017.
6 February 1971: Astronaut Alan Shepard uses a 6-iron to hit a golf ball into a lunar crater in a lighthearted moment during the Apollo 14 mission. This was the first real mission devoted to science on the moon. Apollo 11 and 12 were more about getting to the moon and back. Apollo 13 should have been the science mission, but wasn’t as we all know know.
1 February 2003 9:00 AM Eastern Standard Time: STS-107 disintegrated over eastern Texas during reentry. A briefcase sized piece of insulating foam broke off the external fuel tank during launch and struck the leading edge of the left wing at 3000 km/h. Impact damage to the thermal protection system 17 days earlier allowed hot gases to penetrate and destroy the internal wing structure during reentry.
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.
28 January 1986 11:39 AM: The Space Shuttle Challenger on mission STS-51-L broke up over the Atlantic Ocean 73 seconds after liftoff. An O-ring in the right solid rocket booster failed. A jet of burning solid rocket fuel began escaping from the leak which cut a hole in the large, orange external fuel tank. The tank ruptured, the liquid hydrogen and oxygen mixed, a massive fireball erupted, and the orbiter was torn to pieces. Debris rained for several minutes afterward. The crew compartment remained intact. Any astronauts who remained alive after the disintegration of the orbiter died when the crew compartment impacted the ocean.
Bednorz & Müller discover high temperature superconductivity (1986)

27 January 1986: Johannes Georg Bednorz & Karl Alexander Müller at the at the IBM Zürich Research Laboratory discover high temperature (Tc = 36 K) superconductivity in the copper containing ceramic (LaB)2CuO4.
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 Wednesday, 27 January 2016
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?
