Tracking the ESSA-2 Weather Satellite
John Macphail and Charles Taggart set their Crown SS800 data recorder to receive 136.5 MHz image telemetry from ESSA-2 as it passes over Toronto, Canada, March 1, 1966. It was a spin-stabilized operational meteorological satellite. The 132 kg spacecraft launched from from Cape Canaveral, Florida by a Three-Stage Delta rocket on February 28, 1966 into a 113 minute, 1355×1455 km, sun-synchronous 101° inclination polar retrograde orbit. The spacecraft was an 18-sided polygon, 1.07 m in diameter by 56 cm high, made of aluminum alloy and stainless steel reinforced baseplate carrying most of the subsystems and a cover assembly (hat) then covered with 9,100 1×2 cm solar cells for charging 63 nickel-cadmium batteries. Two redundant wide-angle Automatic Picture Transmission (APT) cameras were mounted 180° apart along the side of the cylindrical craft. Projecting downward from the baseplate were a pair of crossed-dipole command reception antennas. A monopole telemetry (136.500 MHz) and tracking (136.770 MHz) antenna extended outward from the top of the cover assembly. The satellite spin rate was controlled by means of a Magnetic Attitude Spin Coil (MASC), with the spin axis maintained normal to the orbital plane (cartwheel orbit mode) to within ±1°. The MASC was a current-carrying coil mounted in the cover assembly. The magnetic field induced by the current interacted with the earth's magnetic field to provide the torque necessary to maintain a desired spin rate of 10.9 rpm. The "cartwheel" configuration of the TIROS-9 was selected as the orbital configuration for the ESSA satellites. Therefore, a camera could be pointed at some point on Earth every time the satellite rotated along its axis. The spacecraft operating system was the same as on the TIROS-9. The APT system was designed to transmit an image every 352 s, each photo covering a 5180 km˛ area with 3 km resolution. Its mission was to provide real-time pictures of cloud cover using the automatic picture transmission system. These cloud cover pictures were used by meteorologists for use in weather forecasting and analysis. ESSA-2 was able to transmit two to three images daily to individual ground stations, regardless of their location. The satellite provided useful cloud pictures for more than 4 years before the camera systems were placed in standby mode on March 20, 1970. ESSA-2 was fully deactivated on October 16, 1970. By this time the Environmental Science Services Administration (ESSA) was replaced by the new National Oceanic and Atmospheric Administration (NOAA).

I bet that didn't turn out well. Maybe they need one of these:

Above are three photos of the notorious "Bradbury Corner" area near Edmond, Oklahoma on Route 66. The first is Route 66 with heavy traffic near Edmond, Oklahoma in 1949, and the dangerous intersection is known as Bradbury Corner coming up at US 66 and 77. It was named for Bradbury's Station.
The next two are of Bradbury's Station and an aerial photo of Bradbury Corner with Bradbury's Station to the left.
Everett Bradbury established Bradbury's Station in 1923, located approximately at the southwest corner of the current intersection of Second and Interstate 35.
Today the Rt66 and Hwy 77 are not an intersection, they combine and are a four lane road called 2nd street by locals and goes to downtown Edmond, OK, and turns south at Broadway St.
Rt 66 Rt 77 continue south for several miles before they split into separate roads where 77 becomes an interstate grade road also called Interstate 235 and is a major commuter road between Edmond and Oklahoma City.
The photos are courtesy of 66postcards, the Edmond History Museum, and the Oklahoma Department of Transportation.

Did they invent the Turbo Encabulator also? Sounds like one author wrote both of the descriptions. 😂

The original machine has a base-plate of prefabulated aluminite, surmounted by a malleable logarithmic casing in such a way that the two main spurving bearings were in a direct line with the pentametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-delta type placed in panendermic semi-bovoid slots in the stator, every seventh conductor being connected by a non-reversible tremie pipe to the differential girdlespring on the "up" end of the grammeters.

I think that article is designed for radio geeks and has way more technical information than most people understand.










Atomic Clock. Clock (B) Readings from the Maser are taken by Dr. T.C. Wang (left) and Dr. J.P. Gordon, who helped develop the atomic clock. The instrument will find commercial use in testing television frequencies, helping pinpoint the position of ships at sea as well as checking with utmost accuracy the Earth's period of rotation. 1955


In structural geology, a fold is a stack of originally planar surfaces, such as sedimentary strata, that have been bent or curved during a permanent deformation. The lower Ugab River valley of Namibia is an impressive example of such a process.

Charlemagne's Throne erected in the 790s by Charlemagne (located in Aachen). From then until 1531, it served as the coronation throne for thirty-one Kings of Germany. The throne rests on four stone pillars. This made it possible for visitors in later times to crawl under the throne, simultaneously a demonstration of humility to the newly anointed ruler and an act of veneration for Jesus Christ, who was related to the throne by the depiction on the rear marble plaque

What are those red filaments in the sky? They are a rarely seen form of lightning confirmed only about 30 years ago: red sprites. This image was taken by Yuri Beletsky in 2021 from Las Campanas observatory in Chile.

Looks like he could flip the tire and get another season out of it!
