Planets I Learned About Via Youtube While Procrastinating My English Essay

Ep. 22 African-American Astrophiles - HD and the Void

As Black History Month 2018 wraps up, learn about some of the African-American men and women who have contributed to space research and exploration! 7 astronomers and 9 astronauts shine in this episode, which spans from the 1700s to modern-day folks.

February is Black History Month, and it’s been the perfect excuse to research all of the African-American people who have contributed to space research and exploration! I talk about seven astronomers and nine astronauts who have delved into outer space because it was just so dang amazing, nothing could stop them from learning about it; astrophiles, if you will. Space-lovers.

Below the cut, I have the transcript, sources, music credits, and timeline of people I talked about! Maybe you have something you want to hear me talk about that’s related to space. I’m kind of set for topics for the next few months but I’ll take suggestions here or you can tweet at me on Twitter at @HDandtheVoid, or you can ask me to my face if you know me. Please subscribe on iTunes, rate my humble podcast and maybe review it, and tell friends if you think they’d like to hear it!

(My thoughts on the next episode are the SOFIA observatory, Chuck Yaeger, the transit of Venus, or quasars and blasars. The next episode will go up March 19th, unfortunately; I have a work retreat the day I’d usually post and I don’t trust the wifi out there. See you then!)

Mae Jemison: “I followed the Gemini, the Mercury, and the Apollo programs, I had books about them and I always assumed I would go into space. Not necessarily as an astronaut; I thought because we were on the moon when I was 11 or 12 years old, that we would be going to Mars—I'd be going to work on Mars as a scientist. And that's despite the fact that there were no women, and it was all white males—and in fact, I thought that was one of the dumbest things in the world, because I used to always worry, believe it or not as a little girl, I was like: What would aliens think of humans? You know, these are the only humans?”

The Moon of Lakes and Rivers - Saturn’s moon Titan

Saturn’s moon Titan is the only world - other than earth - that we know has liquid’s pooled on its surface. Unlike Earth, Titan has lakes of liquid methane - you wouldn’t want to swim in these lakes.

Titan’s “methane cycle” is analogy to Earth’s water cycle. In the 3rd and 4th images above we can see clouds of methane in Titan’s atmosphere. Ever since NASA’s Voyager 1 spacecraft, we have known that the gases that make up Titan’s brown colored haze were hydrocarbons. The atmosphere of Titan is largely nitrogen; minor components lead to the formation of methane–ethane clouds and nitrogen-rich organic smog.

It is thanks to the Cassini spacecraft that we now understand more about the climate of Titan - though we still understand very little!

The Cassini Space craft has mapped most of the Northern polar region of Titan, this is the region that contains almost all of Titan’s lakes. Cassini is systematically sweeping across Titan and mapping the surface of this strange alien world. The image below is an example of Cassini’s mapping process:

Cassini prepares for final orbital “Grand Finale” at Saturn.

Erik Wernquist, the same filmmaker who created 2014’s “Wanderers” and a stunning New Horizons promotional film in 2015, has created a new video highlighting NASA’s Cassini mission’s final days at Saturn. The Cassini spacecraft will begin its final series of orbits to cap a 13-year groundbreaking science mission known as the Grand Finale. For the first time ever in Cassini’s time at Saturn, the spacecraft will fly in between the planet’s rings and atmosphere. No spacecraft has ever before flown in this region of any of the solar system’s ringed planets. After 20 orbits, Cassini will dive into Saturn’s upper atmosphere September 15 where it will be destroyed. In 2008, mission managers explored a range of End of Mission scenarios that would protect Saturn’s moon’s from Earthly contaminants before ultimately deciding on atmospheric reentry. Cassini began her End of Mission manoeuvres on November 26, 2016, when it began the first of 20 ring-grazing orbits. A close flyby of Titan April 22 will alter the spacecraft’s trajectory to begin the first of 23 orbits in the Grand Finale, which will begin April 26.

Cassini launched from Earth on October 20, 1997, and entered Saturn orbit July 1, 2004. 16 days later, the European-built Huygens probe attached to the spacecraft landed on Titan, becoming the first probe to land in the outer solar system. Originally scheduled for a four-year mission ending in 2008, Cassini received two mission extensions in 2008 and 2010, with the latter ending in 2017. With the spacecraft’s fuel reserves low, the Cassini team decided to end the mission. P/C: JPL/Erik Wernquist
