Because the Earth doesn't exist

>>7409026

the better question is why do NONE of these probes (mars stuff etc) never have an earth facing camera as they head off into the solar system.

Are we really content with some piece of shit picture form apollo 50 years ago?

Perhaps because its been covered pole to pole by satelites. Try google maps.

>>7409026
Because the earth is flat and NASA is covering it up.

>>7409053

They did recently. though it was only with one of their shit navigation cameras

>>7409063

that looks like utter shit

why cant they just take a god damn picture when it is the distance they were with apollo

>>7409065

Well they only realized that they could make an earth flyby and photograph the earth after the probe was already in flight so there wasn't really anything they could do about the quality.

Also, the apollo missions went nowhere near as far out as the probe is

We have hundreds of satellites in orbit taking pictures continuously...

Spacecraft leaving earth are spin stabilized, with their high gain antennae pointed at the earth. It would be way too risky to despin, point the antenna away from the earth, take a picture of the earth, point back at the earth and spin up again just to get a picture of the earth with no scientific value whatsoever.

>>7409086

are u retarded?

put a fucking camera on the back of the spacecraft

>>7409026

Because there's plenty of pictures of earth already.

For example, here's a picture of an old barn.

>just to get a picture of the earth with no scientific value whatsoever.

you act like there is scientific value in getting pics of gay ass pluto

Oh look, we've got a NASA engineer here.

>>7409142

huh? can you tell me one good reason why you cant glue a galaxy s2 to the back of the craft?

christ

>>7409116
Teehee

>>7409144
It would cost 5000 dollars plus the cost of the phone. Nasa isn't made of money.

>>7409144
>glue a galaxy s2

I think cell phone service is pretty weak at that altitude.

Will donate a used phone. 6mp should be enough, right? Seriously though, that is a pretty lame reasoning not to install a rear facing camera, it would be a matter of one sensor and a set of wires. Chinese kids build more advanced technology for pennies a week.

wastes bandwidth and cpu time during an important maneuver; the moon slingshot

fuck that up and they wont make it to jupiter let alone pluto

remember the rocket doesnt come out perpendicular to earth because that wastes delta V

>>7409116
Thank you. I saved the picture, I will have Steve print and frame it for me tomorrow.

>>7410542
On top of these reasons is weight

thousands of dollars per pound
NASA's budget isnt limitless so cutting corners is the culture

also even a small last minute increase in weight requires you to recalculate several sensitive factors and trajectories which would make the difference between getting to pluto or ending up in a shitty orbit around the sun somewhere between earth and jupiter

>>7410529

>i have no idea how cameras work
>this makes me an expert on the subject.


your shitty 6mp phone camera trying to photograph earth from that distance will just look like a white picture from the sun washing everything out

also, pointing such a sensitive camera at the sun for a picture with zero scientific value will likely ruin the camera.

basically, you are a faggot.

>>7409058
Yeah who would want a totally fucking sick picture of Earth surrounded by satellites just like muh sci fi animes?

>>7410545

WHO THE FUCK IS STEVE

>implying you'd see any fucking satelite from a distance you could see the earth as a whole

For what benefit should a spacecraft carry around a rear-facing camera for the duration of its entire mission?

>>7409026
because all of those missions sent spacecraft to a higher orbit around the sun, which would leave the earth in the dark relative to the spacecraft, so it wasn't worth it to wast the RCS fuel to turn the spacecraft around to look at it

>>7412081
But then how can we prove to internet degenerates that Earth exists?

>>7409026
The pale blue dot doesn't matter anymore.

>>7409144
Advanced as the s2 is, it doesn't have a time travel app.

>>7412091
a lunar eclipse. if the earth was flat model was correct, the earth wouldn't be able to even cast a shadow on the moon because the earth couldn't be between the moon & sun. Especially not a round one.
