Katherine Johnson of NASA

A NASA Legend

Katherine Johnson passed this week at the impressive age of 101.

For those of you who may now know who she was, Johnson was an American mathematician who worked for NASA. Her calculations of orbital mechanics were crucial to the success of the first (and following) American spaceflights. NASA says she had the “historical role as one of the first African-American women to work as a NASA scientist.”

In 2015, President Barack Obama awarded Johnson the Presidential Medal of Freedom and in 2019 she was awarded the Congressional Gold Medal.

The 2016 movie Hidden Figures was in part about Johnson. She was portrayed by actress Taraji P. Henson.

A Mini-Moon

In space-related news, Earth seems to have picked up an orbiting object.

Last week astronomers at the Catalina Sky Survey in Arizona noted a dim object that moved quickly across the sky. Skywatchers at several observatories kept an eye on the object, which is now designated “Temporarily Captured Object 2020 CD3”. It’s been orbiting the earth for around three years.

Scientist Kacper Wierzchos, who works with the Catalina Sky Survey, shared an animation of the object, which you can check out below.

The announcement (which you can read here) was posted by the Minor Planet Center, which monitors small bodies in space. It says “no link to a known artificial object has been found,” which tells us that it’s a naturally-occurring body such as an asteroid.

They also noted that 2020 CD3’s orbit is unstable so it will eventually escape orbit and away from Earth once again.

It’s quite small at around the size of a small car, so don’t get too excited for naked-eye sightings of 2020 CD3.
