Mathematician. Leader. Heroine. Remembering Hidden Figure Katherine Johnson

Tonight, count the stars and remember a trailblazer. 

We’re saddened by the passing of celebrated #HiddenFigures mathematician Katherine Johnson. She passed away at 101 years old. 

An America hero, Johnson’s legacy of excellence broke down racial and social barriers while helping get our space agency off the ground.

Once a “human computer”, she famously calculated the flight trajectory for Alan Shepard, the first American in space.

And when we began to use electronic computers for calculations, astronaut John Glenn said that he’d trust the computers only after Johnson personally checked the math.

As a girl, Katherine Johnson counted everything. As a mathematician, her calculations proved critical to our early successes in space travel.

With slide rules and pencils, Katherine Johnson’s brilliant mind helped launch our nation into space. No longer a Hidden Figure, her bravery and commitment to excellence leaves an eternal legacy for us all.

“We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering and technology. And there will always, always be mathematics.” - Katherine Johnson 1918 -2020 

May she rest in peace, and may her powerful legacy inspire generations to come! What does Katherine Johnson’s legacy mean to you? Share in the comments.

The Full Moon of 2021 via NASA https://ift.tt/3FWxNTm

Every Full Moon of 2021 shines in this year-spanning astrophoto project, a composite portrait of the familiar lunar nearside at each brightest lunar phase. Arranged by moonth, the year progresses in stripes beginning at the top. Taken with the same camera and lens the stripes are from Full Moon images all combined at the same pixel scale. The stripes still looked mismatched, but they show that the Full Moon’s angular size changes throughout the year depending on its distance from Kolkata, India, planet Earth. The calendar month, a full moon name, distance in kilometers, and angular size is indicated for each stripe. Angular size is given in minutes of arc corresponding to 1/60th of a degree. The largest Full Moon is near a perigee or closest approach in May. The smallest is near an apogee, the most distant Full Moon in December. Of course the full moons of May and November also slid into Earth’s shadow during 2021’s two lunar eclipses.
