Q: What is the name of the polyhedral shape of the Humanity Star?

uhohRocket Lab has successfully launched a rocket from New Zealand and placed several objects in orbit, see here for example. One payload is New Zealand's first satellite the Humanity Star, a reflective geodesic that can be seen at night by reflected light. According to this it has 65 sides. What i...

@kimholder fyi the Humanity Star's shape is the same as the default icosphere in Blender (subddivisions = 2) except for that 36° between the top and bottom halves (the two "birotunda") as described in math.stackexchange.com/a/2620121/284619
Maybe the Moon needs a sister Humanity star?

@uhoh That's pretty neat. I'm going to have to make sure i see it on its first visible pass over Mexico.
In an early piece of writing i actually proposed something like that, but much more ambitious, for the Moon. A field of mirrors that rotated in sync to reflect sun towards the Earth. The size of field wasn't all that bad, really, for decent visibility. I think it was a square about 2 km on a side.

The poor girl in this one tries so hard not to laugh. But he is really good on the rubber chicken. Who knew?
He also uses a Rubber ducky and pig at times (Oh ya, a piano that plays Meow sounds only). Like in this Coldplay cover, that is really good.

Q: Why would Humanity Star not be visible from North America until March?

uhohA quote near the end of the BBC's article 'Disco ball' put into space from NZ says: Jonathan McDowell, a satellite-tracker and astronomer at the Harvard-Smithsonian Center for Astrophysics, commented: "The irony is that it's poorly placed for observation right now - low on the horizon for ev...

@kimholder we'll have to keep an eye on its visibility issues

oh, that bad huh? i looked at the track and i could tell it would be a while, but i didn't think it would be over a month.
i wonder if they included dawn sightings in that... seems like an awfully long time alright

@kimholder how did you look? The only think I know how to do is download the TLE's and propagate in Python, and don't have time to do that
Consider posting an answer there?
kim holder
kim holder
it would be a very partial answer... i just looked at the tool they have on the website you linked to.

no, i do hope they update it. It doesn't tell you what you need to know right now, really.

OK we'll wait for the satellite expert to solve this mystery.

$195 to see the FH from 6 km away.... would i pay that... maybe...
i would not pay $75 to see it from 12 km away

Nope. I've decided i'm all about Jetty Park Beach and Pier. Closest you can get to the landings.

A: At what exact time was the Pale Blue Dot image taken?

Emily LakdawallaAs far as I know, the raw data used to make the Pale Blue Dot image have not been preserved in NASA's Planetary Data System, which is why other commenters can't find it online. You might try contacting someone at the PDS Rings Node to see if anybody there has the data and metadata.

signed, Emily Lakdawalla...

I can't remember if you have to verify you own an email.

Anyone have any feelings about mass-editing "manned" and "man-rated" to "crewed" and "human-rated" in Q/As? I'd put in the work but I /hate/ that questions get bumped to current for minor edits.

@RussellBorogove being the person who asked for that change to the tags in the first place, i don't recommend it. I do prefer the neutral tag, but some people don't, and don't like it being changed.

it led to an argument once before, and i just don't think it's worth it. I accept the stance that some people use it without any intention to be sexist, so making a change can lead to unnecessary issues.
