NASA’s longest serving female employee since January 1958, Sue Finley, has been an engineer and programmer for space missions since Explorer 1, for missions to the Moon, Sun, all the planets and many other solar system bodies, and recipient of NASA’s Exceptional Public Service Medal.

Susan G. Finley Susan G. Finley, a native Californian, has been an employee of NASA’s Jet Propulsion Laboratory (JPL) since January 1958, making her the longest-serving woman in NASA. Two days before Explorer 1 was launched, Finley began her career with the laboratory as a human computer, calculating rocket launch trajectories by hand. She now …

In 1969, at the height of the Cold War, the Apollo 11 crew carried commemorative medals to the moon to honor two Soviet cosmonauts who died as part of the USSR’s human spaceflight program

Statement About Honoring American and Russian Space Heroes During the Apollo 11 Mission THE TWO MEN we hope will set foot on the moon represent all mankind. Their achievement will be the world’s achievement. It is fitting, therefore, that the first lunar explorers carry with them some recognition of the sacrifice made by other space …

Buzz Aldrin, the second man on the moon, singlehandedly calculated an orbital technique called “Mars Cycling” which would allow for spacecraft to perpetually travel between Earth and Mars with only a single initial boost. Crew would board and return via a secondary spacecraft, saving fuel.

Mars cycler Buzz Aldrin, discoverer of the Aldrin cycler A Mars cycler (or Earth–Mars cycler) is a kind of spacecraft trajectory that encounters Earth and Mars regularly. The term Mars cycler may also refer to a spacecraft on a Mars cycler trajectory. The Aldrin cycler is an example of a Mars cycler. Cyclers are potentially …

When the replacement crew for Skylab entered the empty space station, they found that it wasn’t empty at all: 3 figures were inside. Upon further inspection, the replacement crew found out that these were dummies placed in flight suits by the previous Skylab crew before they left.

Skylab 4 Skylab 4 (also SL-4 and SLM-3) was the third crewed Skylab mission and placed the third and final crew aboard the first American space station. The mission started on November 16, 1973 with the launch of three astronauts on an Apollo command and service module on a Saturn IB rocket from the Kennedy …

Doctor Who briefly featured Kamelion, an android who was “played” by an actual robot. Unfortunately, the writers had to kill the character off when the robot’s inventor, who was the only one who knew how to control it, died in a boating accident.

Kamelion When Kamelion changed shape, it was played by the actor whose character’s form it took. However, when in its default form, it was a true computer-controlled robot prop. The reason why the Kamelion robot was used fully only in two serials was that it was very difficult for the Doctor Who production team to …

When NASA used electronic computers for the first time – to calculate John Glenn’s orbit around Earth – officials called on Katherine Johnson to verify the computer’s numbers; Glenn had asked for her specifically and had refused to fly unless Johnson verified the calculations.

Katherine Johnson: Hidden Figures Nasa mathematician dies at 101 Reuters Pioneering African-American Nasa mathematician Katherine Johnson has died at the age of 101. Nasa announced her death on Twitter, saying it was celebrating her life and honouring “her legacy of excellence that broke down racial and social barriers”. Ms Johnson calculated rocket trajectories and Earth …

Neil Armstrong’s heart rate spiked to 150+ when NASA turned the control over to him for the moon landing.

The Apollo 11 mission as told through the astronauts’ heart rates Those heart rate figures are what aerospace experts would expect to see for experienced, physically fit astronauts enduring the stresses of the launch. All three had flown to space before, during the Gemini program, and during that first launch, all three of their beating …

The common method for a spacecraft to shift between two orbits is called a Hohmann Transfer, and that the guy who calculated it (in 1925) was inspired by a science fiction book written in 1897, which gave a generally correct explanation of the concept of orbit trajectory

Hohmann transfer orbit Hohmann transfer orbit, labelled 2, from an orbit (1) to a higher orbit (3) An example of a Hohmann transfer orbit between Earth and Mars, as used by the NASA InSight probe. Hohman · Earth · Mars In orbital mechanics, the Hohmann transfer orbit (/ˈhoʊmən/) is an elliptical orbit used to transfer …
