For #spacetober_challenge day 31 prompt future: “Take the Europa Express, your passport to the Galilean Moons!” 🧪🐡 My linocut is a space travel poster for a future where we all share the citizenship of Earth and can take rapid transport to Europa, one of Jupiter’s moons, known as the Galilean Moons (named after Galileo, who first observed them with a telescope). 🧵1/2

For #spacetober_challenge prompt day 30: galaxy - astronomer Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & evolution of our universe! The Nobel committee waited 3 years after she died to reward another for the theory of dark matter. 🧵

For #spacetober_challenge day 29 prompt orbit: #mathematician and #astronomer Johannes Kepler (1571-1630)! We remember him for his role in the Scientific Revolution, and his three laws of planetary motion in particular. His laws modified Copernicus’ heliocentric model; he replaced the circular orbits with elliptical ones & described velocities of planets. Today we know them as:

Happy birthday to #mathematician & geodesist Gladys West (née Brown 1930)! Shown with 3 satellites important to her career + tracks: Seasat, GEOS-3 & a GPS satellite. Her work, using math to precisely model the shape of Earth, laid the groundwork for GPS! Born to sharecropper parents in Virginia, she graduated with a Math BSc in ‘52 then MSc at VSU in ‘55. She started her career at 🧵

For Day 25 #spacetober_challenge: historic missions- my portrait of mathematician and NASA scientist Katherine Johnson (née Coleman; August 26, 1918 – February 24, 2020). One of the first Black women employed as a NASA scientist (and its predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics and played a pivotal role in the success of the US crewed spaceflights from the beginning. 🧵

For the #spacetober_challenge day 24 prompt jet/plane I made a new #womenInSTEM #linocut: trailblazing Canadian aeronautical engineer Elsie MacGill (1905 – 1980), born in Vancouver, became the first woman aeronautical engineer & professional aircraft designer in North America, & likely the world. She collaborated on many of Canada's famous & innovative bush planes & aircraft components, was entirely responsible for 🧵1/

For Day 21 of @spacetober_challenge #spacetober_challenge prompt star: trailblazing US #astronomer Annie Jump Cannon (1863 – 1941), here with her stellar classification system which sorted stars based on spectral types, revealing their temperature from hot blue to cool red stars: O,B,A, F, G, K & M. Named the Harvard Classification after the university, her tremendous contribution was less visible. 🧵1/

For #spacetober_challenge prompt telescope: #astrophysicist Jocelyn Bell Burnell as a grad student in ‘67 discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. This radiation can only be observed when the star is pointed towards us; so, like the light from a lighthouse, it appears to pulse at a precise frequency. She had been working with her supervisor Hewish & others to construct a radio telescope 🧵1/
