This guys does GOOD visualization work!

PearsonArtPhoto

Wow!

geoffc

He has been doing this after most launches, updating as more data comes in. I think he has an app that scrapes the video for time and speed/altitude values.

So Roadster/ Starman will actually have a pretty close pass of Mars in 2020.

Q: Can this Duplicate message be removed?

This answer on escape velocity is better and simpler for laymen than this one, and should not be closed as duplicate. As soon as read the first paragraph from here, I got it! As opposed to the mathematically intense answer here which I could not follow. Feature request: Perhaps [Simple answe...

PearsonArtPhoto

Anyone on that can offer an opinion?

Is whereisroadster.com/test.html looking better then the current main page?

PearsonArtPhoto

1:45 AM

Never mind, I'm just going to push it.

Next up: Tabs.

And maybe I'll even do a real 404.html page too... Nah, I'll save that for later.

@PearsonArtPhoto - looks good!

Making some progress now...

I've now created 4/7 pages that will eventually be shown on the site. I think the next is the "About" page, which will include contact information as well as some of the way the plots were generated. I might even include a link or two to Space.SE.

Close approaches should be pretty easy to do as well. I might do something more with it later, but...

Views will be my project for next week...

BTW, I added a link on whereisroadster.com/goodies.html to the mission patch.

Q: Might the SpaceX Roadster intercept any ongoing surveys?

There are star survey telescopes in space, and on Earth. I don't really know how to begin to know where they will all be looking for the next few months. On the off-chance that someone does, or can suggest how to find out in a systematic way, I thought I would ask here. These is JPL's Horizons p...

This is how it looks here - a banner add for RT-Mart

It's shaping up very nicely!

@PearsonArtPhoto But it would be nice on your graph if the pixels per AU were the same for X and Y. Those elliptical orbits with the Sun in the CENTER are just troubling.

But then again, I'm a resident "stickler"

What are Repux ERC20 Tokens?

You're getting MITM'd.

uhoh

@RussellBorogove some people collect stamps from around the world. I thought "what ads look like here" would be mildly interesting.

Luckily I can not read them!

One of the benefits of not knowing the language (or nearly so) is that it is both visually and aurally "quieter" wherever I go.

Russell Borogove

I agree with uhoh that the different horizontal/vertical scales is confusing. It'd be nice if the big distance numbers could be commatized (e.g. The car is 145,001,402 miles (233,357,209 km) from Mars) (assuming you want to avoid scientific notation).

Does your plotting library offer anti-aliasing?

PearsonArtPhoto

@uhoh Yeah, I need to improve that. It is better now then it was, but I do agree. Will add that to my today list.

Space Exploration Meta

Q: Would putting links to Space Exploration Stack Exchange on PearsonArtPhoto's website be a good thing for this site?

From here: I might even include a link or two to Space.SE. Any thoughts on this?

See, this is why you should never start a public project... you wind up with a bunch of kibitzers giving you more work to do

deostroll

why is starman's car going round and round...? Sometimes we see the reflection of the earth on the car...is it the harness the car is mounted on (in other words is it manually doing this) or is it a feature of how its put into its current orbit...? youtube.com/watch?v=m2p55BmwmJM

@uhoh What do you think of this?

Edlothiad

@uhoh oh god I completely forgot RT Mart was a thing

PearsonArtPhoto

@uhoh Interesting choice of ads... I haven't done that page yet, it's on my todo list for the day.

Edlothiad

@deostroll too give you a basic quick answer, it’s for stability, I believe. The whole second stage is spinning

Would normal satellites do something like this? @Edlothiad

7:00 PM

Not the person to ask, but as far as i’m Aware yes

That could be a total lie though, I’m here to learn still, so I shouldn’t really answer such questions as an “expert”

Wikipedia seems to say sometimes as a form of attitude control

Attitude control

Attitude control is controlling the orientation of an object with respect to an inertial frame of reference or another entity like the celestial sphere, certain fields, and nearby objects, etc. Controlling vehicle attitude requires sensors to measure vehicle orientation, actuators to apply the torques needed to re-orient the vehicle to a desired attitude, and algorithms to command the actuators based on (1) sensor measurements of the current attitude and (2) specification of a desired attitude. The integrated field that studies the combination of sensors, actuators and algorithms is called "Guidance...

Okay, so I need some advice. I have been requested to add a distance travelled for Starman. I'm not sure what frame of reference I should use. Any thoughts?

I don't really think heliocentric is the way to go.

I guess I could just only add distance relative to Earth, either coming or going towards.
