Speedometer (such a unique name, I know) is a basic, no-frills speedometer. It supports mph, km/h, m/s, and Mach (just in case.)

Background info

On May 2, 2017, Tom Mueller, propulsion CTO at SpaceX, conducted a speech/interview with some members of the New York University Astronomy Society. This was streamed live on Twitch; I’ve transcribed it with the help of u/dansemacabred2, u/jclishman, and u/Zucal. Many thanks!

Check out the interview on twitch.tv, and the post in the SpaceX subreddit.

post I'm now on Patreon. 2017-04-27 00:00:00 +0000 UTC

For some background, I’m currently creating all of my illustrations from a 2012 laptop (Lenovo T430, if you’re curious,) and it’s… not the ideal 3D graphics computer, to say the least. I’d love to upgrade, but it’s only necessary for 3D work; and I was (understandably) wary to spend money on a new computer without any way to recover the costs.

So I’ve made a Patreon page. Apparently, people actually like my work enough to send me some money for it; until now, the only way was via RedBubble (where I get 30% of the total item cost), or direct donations. Hopefully, there will be more incentive for people to pledge to me on Patreon, thanks to the rewards.

This piece shows the SpaceX Interplanetary Transportation System Mars lander performing the trans-Mars injection burn that marks the beginning of its coast to Mars.

My rendition of a Falcon 9 booster landing on Of Course I Still Love You, SpaceX’s East coast droneship. This is a triple-engine landing burn; while SpaceX hasn’t performed a triple-engine landing burn since JCSAT-16, very heavy GTO payloads at the edge of Falcon 9’s capability may require triple-engine landing burns in the future.

My rendition of a Falcon 9 booster returning to Earth after a launch. The four grid fins are guiding it towards its landing pad as it hurtles downwards at supersonic velocities.

In this image, the Falcon 9 is at about 40km in altitude (with entry burn shutdown having occured seconds earlier) and is less than thirty seconds from the start of the landing burn.
