Mae Jemison

When I took AP U.S. History in high school, we did a project called "Historical Character Day" after completing the lengthy coursework and dreaded AP exam. We could chose to be any significant person in American history and had to pretend to be that person, introducing ourselves to the entire class and then interacting with other important, well-known people of history. So, as you might have already guessed, I chose to be Mae Jemison. 
portrait of Mae Jemison
The following is the information I collected as I prepared for Historical Character Day so that I would be able to fully know my person inside and out:


Name:  Mae Jemison
Born:  October 17, 1956
Contribution to History: the first black female astronaut


Significance to America:
  • First African American woman admitted to the space program and in space
    • Science Mission Specialist
  • Advocate for women’s and civil rights
  • Area Peace Corps medical officer for Sierra Leone & Liberia
  • Awards:
    • 1988 - Essence Science and Technology Award
    • 1992 - Ebony Black Achievement Award
    • 1993 - Montgomery Fellowship from Dartmouth College
    • 1990 - Gamma Sigma Gamma Woman of the Year
    • 1992 - public school in Detroit named after her
    • 2004 - International Space Hall of Fame
    • 1993 - National Women’s Hall of Fame
  • Organizations:
    • American Medical Association
    • American Chemical Society
    • American Association for the Advancement of Science
    • World Sickle Cell Foundation
    • American Express Geography Competition
    • Center for Prevention of Childhood Malnutrition
  • Established Jemison Group, a company for research, development, and marketing of advanced technologies
  • Established The Earth We Share, a science camp to encourage (especially girls) to learn about science & global issues
Fun Facts:
  • She can speak Russian, Japanese, and Swahili
  • She started college at Stanford University at 16 years old and then went on to med school at Cornell
  • She worked in Cambodian refugee camps
  • Her space shuttle, Endeavour, was the only one named by children
  • Was featuered in LEGO's "Women of NASA" set [read my post about it here]
  • Made an appearance in Star Trek: The Next Generation
  • Is an advocate for peace and equality
  • Favorite Hobby: theater/dance
  • Favorite Music: modern jazz, African dance, West Side Story
  • Favorite Book: A Wrinkle in Time & The Arm of the Starfish [because they each feature female scientists heroines]
  • Favorite Subject in School: science and technology, but also loved art just as much
  • Other Interests:
    • cooking
    • watching movies
    • weight lifting
    • gardening
    • traveling
    • photography
    • skiing
    • volleyball

As part of the project, I had to describe the type of person I'd see myself (Mae Jemison) getting along with the best:
Someone who supports human rights and has a heart for all people no matter their race, gender, social standing, etc. Someone who is interested in science and technology, but also has an appreciation for the arts. Someone who loves learning and new experiences and is always up for an adventure and likes nature and serving others. Someone who will support me on all my endeavors (no pun intended).

Image result for mae jemisonWe also had to bring in a food that the person liked/would have eaten in that time. I spent a long time looking for different 'space food' recipes and came across a video of Chris Hadfield making a sandwich out of a tortilla with peanut butter and honey. They use tortillas in space instead of bread because it doesn't make crumbs and it is more compact, thus avoiding bread crumbs from floating around in zero gravity. So I brought in these 'Space Shuttle Sandwiches' or what I liked to call PB&Jems.


On Historic Character Day, I wore a NASA tee shirt and I even spoke a little bit of Swahili ... or what I was able to learn from Google Translate ;)
Unaweza Daima Ngoma Kama Wewe Ni Daktari Lakini Huwezi Daktari Kama Wewe Ni Damfe  -- “You can always dance if you’re a doctor, but you can’t doctor if you’re a dancer”

Some of the amazing people I (as Mae Jemison) had the opportunity to interact with included: Thomas Edison, Grace Hopper, Elizabeth Blackwell, Louis Armstrong, Sally Ride, Maya Angelou, Eleanor Roosevelt, JFK, and Amelia Earhart ... all of whom were fellow scientists, aviators/astronauts, feminists, and African Americans from various time periods.

Finally, here are a few other quotes from Mae Jemison that I came across in my research that I enjoyed:
“Some of the most fun people I know are scientists” 

“I stayed in the astronaut program until 1993. People ask me why I left. I thought I had a lot of things to contribute that would be difficult to do if I stayed. I thought I could have a stronger voice as an advocate for space exploration. So I ended up starting my own technology consulting company”

“What we find is that if you have a goal that is very, very far out, and you approach it in little steps, you start to get there faster. Your mind opens you to the possibility."

This Day in Space History: November 2

1885

Astronomer Harlow Shapley was born. During his life, Shapley studied stars and galaxies, proving through measurements of star dimensions that the Sun wasn't, in fact, positioned at the center of the Milky Way Galaxy, but 30,000 light years away from its center. At the center of the galaxy were star clusters positioned spherically in Sagittarius. Shapley’s discoveries helped scientists formulate the first realistic estimate of the size of our galaxy which was 10x larger than previously thought. As a research professor at Harvard and the director of the College’s observatory, Shapley observed metagalaxies, proposing his “liquid water belt” or habitable zone theory.

1978

The crew of the USSR's Soyuz 29 mission returns back to Earth aboard Soyuz 31. The mission was launched June 16, 1978 and docked to Salyut 6. The craft returned to Earth September 3rd, but the crew stayed an additional two months. Soyuz 31 was launched August 26th and docked the next day, eventually bringing home Kovalyonok and Ivanchenkov of the former mission in November.

1848

In 1848, two discoveries of Saturn's largest nonspherical moon, Hyperion, were made independent of each other. Those credited with the discovery are both William Lassell (1799-1880) and William Cranch Bond (1789-1859) and his son George Phillips Bond (1825-1868). Learn all about Hyperion here: https://solarsystem.nasa.gov/planets/hyperion

1945

One of the V-2 Blossom rockets exploded after its launch, with cynomolgus monkey Albert III aboard. Albert survived in space but died on impact. Learn about all the Alberts here: http://www.popsci.com/blog-network/vintage-space/alberts-spaceflights-unsung-heroes#page-4

1975

The maiden flight of the Russian aircraft Mikoyan MiG-31 Foxhound. This model is able to intercept, detect, and destroy cruise missiles and carry strategic bombs.  Between 1981 and 1994, 519 crafts were produced and continue to be used. 

1996

Space shuttle STS-79 (Atlantis 17) is launched for its docking on the Mir space station. The mission was delayed three times, first for a change in its assembly and twice in order to avoid Hurricane Bertha and then Hurricane Fran. The mission lasted ten days. Shannon Lucid was replaced by John Blaha as the crewmember for NASA on Mir. One of the power units failed after thirteen minutes, but it was decided that the mission would continue.

1877

Sir James Jeans (1877-1946) was born in London. In his lifetime, this mathematician, physicist, and astronomer would teach at Cambridge and Princeton. Jeans would also study radiation and the stars, including their energy and different types of stars and star systems. He disproved Laplace's nebular hypothesis and supported Thomas C. Chamberlin's catastrophic theory; saying that the planets were formed by the condensing of stellar debris, rather than from a 'single gaseous cloud'. For those interested, Jeans' books are listed here.

1941

https://newspapers.ushmm.org/events/charles-lindbergh-makes-un-american-speech
Shortly before the Japanese attack on Pearl Harbor in a speech in Des Moines, Iowa, great American aviator and, at this time, an isolationist, Charles Lindbergh names three groups he believes are pushing the U.S. to enter the war: "the British, the Jewish, and the Roosevelt Administration."

1967

Launched just three days before, the Surveyor 5 spacecraft lands on the moon, conducts a variety of experiments and sends images back to Earth. In this first lunar day, Surveyor had sent back 18,000 pictures, and 83 hours worth of data on the composition of the moon's soil. Learn more about the mission here: https://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1967-084A

1985

The International Cometary Explorer (ICE) was a repurposed mission - originally the Sun-Earth Explorer-3. When ICE flew by the comet Giacobini-Zinner in 1985, it became the first spacecraft to pass a comet. Learn more about the Giacobini-Zinner comet here:

1857

American astronomer James Keeler is born in Illinois. In his lifetime, Keeler would study at Johns Hopkins, write in science journals, and manage different observatories, where he imaged 120,000 galaxies with a Crossley 36-inch telescope, proving that the most common type of galaxy is the spiral. Among his other achievements include his verification that the rings of Saturn are composed of tiny particles rather than being solid, and his measurement of the rate at which the Orion Nebula expands in the Milky Way Galaxy.

1984

After its first launch on August 30th, the space shuttle Discovery returns to the Kennedy Space Center.

1682

https://www.britannica.com/biography/Edmond-Halley
https://www.britannica.com/topic/Halleys-Comet
What came to be known as Halley's Comet was observed by English astronomer Edmund Halley. Among the many things he studied were comets. Noticing a similarity in the chaarcteristics of comets seen in 1531, 1607, and 1682, Halley determined it was the same comet returning -- Halley's Comet. In his measurements and studies, he accurately predicted its 1758 return. Halley's Comet, which came closest to Earth on April 10, 1986 at 0.417 AU, was the first comet to be imaged by spacecraft. It will next be seen from Earth in 2061.

2011

NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission is launched, sending two twin probes -Ebb and Flow- to orbit the Moon. According to NASA, "The [mission's] goal was to reveal differences in density of the Moon's crust and mantle and will help answer fundamental questions about the Moon's internal structure, thermal evolution and history of collisions with asteroids."

This Day In Space History: August 31

I'm sorry to any English teacher whose pet peeve is the misuse of the word literally, but I'm about to use it anyway...
Literally nothing happened today in space
I mean, 'stuff' happened, but nothing major, nothing earth-shattering, nothing hugely fascinating
Maybe over the course of the next year of research for these posts I will find a new website that will lead me to info to update on 8/31 next year, and maybe something will happen on this date in a future year! But as of now, I am sorry to disappoint, but it doesn't seem like there's anything worthy of reporting!!! 
So I guess this gives me the chance to pre-write future posts as well as finish a separate post I'd started a while ago! And in the meantime... For a complete list of today’s Space History, see  http://www.astronautix.com/a/august31.html

President Ronald Reagan announces the Teacher in Space program, “directing NASA to begin a search in all of our elementary and secondary schools and to choose, as the first citizen passenger in the history of our space program, one of America’s finest—a teacher. All of America will be reminded of the crucial role that teachers and education play in the life of our nation. I can’t think of a better lesson for our children and our country.” After a thorough process, Christa McAuliffe, a teacher from New Hampshire, was selected among thousands of applicants. Unfortunately, a failure with the shuttle Challenger occurred in just 73 seconds, resulting in a loss of all seven crew members. This most tragic disaster is one that all Americans will remember.

With one new planet and one 'old' planet, we've got some pretty cool stuff happening today in the world of space...check it out!


1966

The Soviet Union's orbiter Luna 11 is launched. Read about the mission here: https://solarsystem.nasa.gov/missions/luna_11/indepth

1985

http://www.yearinspace.com/the-week-in-space
Launched a few days ago in 1977, Voyager 2 -the spacecraft we've been following the past couple days- flies by Saturn and in 1989, flies by Neptune.

2006

The conclusion of the 26th General Assembly of the International Astronomical Union (IAU) made the conclusion that the planet Pluto would now be considered a Dwarf Planet, as they refined their definition of what a "planet" is. I remember watching the news with in my parents' room when this happened. A sad day for those who support Pluto's existence as a planet! The excerpt below is from the press release which can be read here: https://www.iau.org/news/pressreleases/detail/iau0603/
The IAU members gathered at the 2006 General Assembly agreed that a "planet" is defined as a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.
This means that the Solar System consists of eight "planets" Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. A new distinct class of objects called "dwarf planets" was also decided.

2016

A telescope at the European Southern Observatory (ESO) in Chile discovered an Earth-like exoplanet called Proxima B, which orbits Proxima Centauri, our closest star (besides our Sun). While the planet is closer to its sun than Mercury is to ours, it has the potential to have liquid water, but the potential for life would also depend on radiation from its sun and whether or not it has an atmosphere. These are two among a list of unknowns which can be found here: https://www.nasa.gov/feature/jpl/eso-discovers-earth-size-planet-in-habitable-zone-of-nearest-star  Who knows, maybe this discovery will be the push we needed to get a spacecraft out there, into another solar system!

This Day In Space History: August 17

1877

Astronomer Asaph Hall (1829-1907) discovers Mars' moon Phobos.

1958

77 seconds after its launch, Pioneer (or Thor-Able 1), a probe meant to orbit the moon, exploded.
"This spacecraft was the first U.S. attempt at a lunar mission and the first attempted launch beyond Earth orbit by any country."  (nasa.gov)

1962

Carl Sagan urges the need to sterilize lunar spacecraft, speculating the probable contamination by terrestrial microorganisms (already by Lunik II and Ranger IV) of both the moon and Earth.

1966

Satellite Pioneer 7 was launched into solar orbit. learn more here: https://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1966-075A

1970

Venera 7 is launched, a mission which would land on Venus and observe its atmosphere. learn more here: https://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1970-060A

2006

Voyager 1 reaches 100 AUs from Earth. If you remember my post where an 1864 comet passed Earth at 0.0964 - that was very close to Earth.
One AU ("astronomical unit") is the approximate distance between the Earth and Sun, equivalent to near 150 million kilometers (britannica.com).
According to NASA, already being the most distant object in space, "'The Spacecraft That Could' Hits New Milestone."

This Day In Space History: August 15

Not much happened today in space, but one especially fascinating thing did happen today. And it has to do with......

      ......ALIENS!

1977

Jerry Ehman, a professor at Ohio State and part of the Search for Extraterrestrial Intelligence (SETI) project, received records of sounds from space, via "The Big Ear" telescope. On August 15, 1977, however, the sounds were different. 6EQUJ5, to be exact. But what significance does that hold? The sound matched the 1959 predicted frequency by Philip Morrison and Giuseppe Cocconi - a 1420 megahertz radio wave, the frequency of hydrogen. So how did Ehman react to the signal? "Wow." The specifics of the signal made it appear to have been produced knowingly. But now the question is what made the noise? Where did it come from? It was tracked back to the Sagittarius constellation. It could have been a natural space sound such as a collision. But since 1977 -40 years ago today- it was never repeated.

We still don't know who or what made that noise, but we know we have not received another seemingly intentional signal from space. Maybe one day we'll come in contact with the sound's source again. Or maybe it will remain a mystery...

as fun as aliens are, I want to acknowledge one more event today...

1986
