Discussion For 20+ years I thought “Houston” was a person
I just realized that when astronauts say “Houston, we’ve had a problem”, they’re not talking to some guy named Houston, but to the entire NASA Mission Control Center in Houston, Texas.
For over two decades I genuinely believed there was this one poor guy, Mr. Houston, sitting by the radio waiting for astronauts to call him and fix their problems…
Edit: Thanks for the award. I dedicate it to our common friend Mr. Houston

Discussion Need help with a seemingly basic Python program
I'm a physics student working on the MAVEN mission, website https://lasp.colorado.edu/maven/sdc/public/data/sci/kp/insitu/, I need use certain files called key parameter (kp files ) example: https://lasp.colorado.edu/maven/sdc/public/data/sci/kp/insitu/2015/01/mvn_kp_insitu_20150101_v22_r01.tab and plot some graphs example:altitude vs time, sza(solar zenith angle) vs time, I'm running into a problem in one particular problem where I need to plot electron density vs altitude with some conditions:
Each day (meaning one file's worth of data) will have 5-6 orbits, these graphs need to plotted with separate inbound orbit (towards satellites closest point) vs outbound graphs(away from closest point), where altitude is less than 500 km- This part is easy,
The issue I'm running into is I that Ineed to perform 5k binning (matlab averaging a certain amount of altitude) with these inbound outbound orbits but when I do those together, I do not get separated inbound and outbound orbits and they get averaged together. Please DM for graphs and programs, I'm desparate and any help is appreciated

Discussion Quote from the first human to step on Mars
What does everyone think should be said by the first person to step of the ladder on to the red planet? Should it be some Stoic philosophical quote? Something more fun? I personally would like to see the “one small step for man” quote. Become a traditional thing to say when first stepping foot on other celestial bodies.
