Good thread, space announcements should always be separate from /sfg/.

Right, NASA is live. Let's see if they can touch some benis.

t. /pol/ (the board with the smartest people)

>Why do they wear the masks

Wow, how exciting. If only asteroid samples didn't fall from the sky literally all the time this would be a pretty big deal.

>>12254169
they look both ridiculous and ineffective

>>12254173
NASA irrevocably irrefutably BTFO

>>12254173
Yeah, not like they get changed from going through an atmosphere or contamination upon contact or anything of the sort, right?

>>12254173
it's not about the sample retard, it's about the first-in-history achievement and testing the tech.

>presenters wear clear masks
>don't give off ANY vapor
>masks not fogging up

presenters = aliens

>>12254169
>>12254183
>the people are on /sci/ right now

Do us a favor and remove yourselves form the gene pool, retards.

Why do gajin chans burst into scratching own pussy when horny?

It is cringe as if it is animal deed
It cools down my blood pressure of dick


Please stop

>no live feed

>>12254193
Bitch, first I was making a joke, and second I don't wear a mask with big ass airholes on the sides.

>literally reading reddit

>>12254203
Even with holes it reduces the forward thrust and redirects it to the sides. Still less spread.

>>12254206
>mentions star wars less than a minute later
cant make this shit up

>Talking over mission coms
Holy fuck spacex just needs to rent out their coverage team.

so no live video? what is the point of a livestream then?

>>12254217
that chick seemed to get a bit pissy when mission coms "interrupted" her

>>12254244
They can run their CGI video and tell you the mission was successful before quietly announcing there were some issues with it 3 days from now.

why arent the masks fogging up? are they reptilians?

>>12254252
>what is ventilation

>>12254259
>ventiliation
then why even bother wearing them?

>nasa big brains literally having plastic bags over their heads
Alex Jones is right, they're freaking alien reptiles

>RGB strip lighting

>All that spit droplets on her mask
wew

>>12254244
nope. We actually won't get images for hours after the event. This is because it has to point the high gain antenna away from earth during the sample operation and the low gain antenna has a bit rate of only 40 bits per second. This is enough to tell the team that something went horribly wrong though. 18 minute light lag too.

>>12254193
you're reading what you want to read. My point was the exact opposite: I object because the lack of a seal would make those masks ineffective. This is a problem because poor communication has lead the public to believe that virtually anything covering mouth will magically prevent infection which in turn leads to reckless behavior. Not all facial coverings are equal:

https://bmjopen.bmj.com/content/5/4/e006577
>The rates of all infection outcomes were highest in the cloth mask arm, with the rate of ILI statistically significantly higher in the cloth mask arm

Performative mask wearing like what they're doing on this stream doesn't help matters, not to mention that looking insane will put people off of the idea entirely.

>>12254207

>Asteroid touching mission thread
>Devolves into a shitty mask discussion
USA was a mistake.

>>12254173
This one will be fresh and uncontaminated though. I mean think about it, would you rather have a fresh piece of meat or one that fell on the ground?

>>12254318
American lives don't matter

>>12254318
I just wanted to banepost

>>12254318
this cunt started it
>>12254169

>>12254332
I don't care who fucking started it. I'm not your parent.

>Burn in two minutes
>Position uncertainty rising

>>12254357
Burn completed, headed towards asteroid

>>12254357
It's still half a meter of uncertainty, which is amazing everything considered.

Just an animation?

Hope they remembered to quicksave

IT'S BENIS INSPECTION DAY!

>>12254367
18 minute lag on a 40 bit low gain antenna. High gain antenna is packed away for the descent.

>>12254207
if you say so
it doesn't really matter anyway

>>12254367
Its so far away that light takes 18 minutes to get here, and the HGA is pointed away from earth during the maneuver. Also it’s gotta send the images aswell wchich takes a long time with a bandwith of like 5.8 kilobytes or something

>>12254367
The available bitrate is just 80 bits per second, with 18 minutes of latency. They're monitoring a spacecraft on the other side of the solar system for fuck sake.

>>12254368
>last quicksave is in Earth orbit

>>12254367
NASA should really prioritize creating a deep space wifi network and sticking video cameras on all their probes, practicality be damned

>>12254262
I think she's hot

>>12254367
antenna can't point at earth during sampling.

>dust experiment from the surface of Kennu
>210 science points
>you look at the sample intently, and can’t quite shake the feeling that it’s looking back at you

>>12254384
this, put signal boosters so it can stream back in 4k ;)

>Stream goes down as they're shilling instagram filters

I was about to turn it off anyway

Did the stream just RIP?

>Cut ze feed

>>12254421
OH NO NO NO the bogtillians are here

>>12254421
Fuck, they found the Bogrelay

>>12254421
BOGDANOF NO

>>12254384
>>wifi
the problem is that we use 'wifi' already. Microwaves spread out quite a bit with distance, so you need a fuck huge dish to get anything and you don't get much signal so transmission is slow. We need use lasers instead, cause they don't disperse as much you get data faster. Lasers are harder because you need finer aim

>>12254421
squint and look at this image

it's an alien

>TOUCHDOWN DECLARED

Go for tag.

>No photos
WE NEED SOMETHING NASA COME ON

That was it? That's all?

>>12254367

They're all a bunch of goofballs and I love it.

NASA too white
problematic

inb4 the return capsule fails

>air-fives

Scotch poured. Slainte.

>>12254459
The real moment is re-entry

>>12254472
do it for grandma

IM GONNA COOOOOOOOOOOOOOOOOOoooOOOooooMMMMM

>>12254455
wait until tomorrow morning. It has to move away from the asteroid and point the high gain antenna back home
>>12254471
They can just pull a hayabusa

>>12254459
if I remember right they also have to make sure that they got a good sample.

I think they both look at it with a camera and determine sample mass by spinning the whole thing around and comparing data to pre-sample shit

>>12254479
I'll do your grandma

>>12254186
>first-in-history achievement
do Americans really?
Haybusa2 lands in december
Hayabusa1 landed in 2010

>>12254489
I've seen this in the video too, there was one mention of sample sharing from JAXA with their Hayabusa sample but seems like it's considered a first for some reason I'm missing

>>12254480
I'M


COOOOMINNGGG

>>12254496
First time *we* have done it.

>inb4 it brings back an alien virus

>>12254505
covid-21

>>12254262
FYI because they are a public service they have to comply with accessibility standards. One of them is access to deaf people. If they wear masks that aren't clear, deaf people have a much harder time figuring out what they're saying because they can't lip read.that's why they have see-thru masks. It was probably cheaper than having a sign language person for everyone at the same time.

>>12254496
Hayabusa2 is actually returning 6th of december
we are dooomed

>>12254480
why did nobody tell me NASA had phat ass scientist thots?

>>12254504
Interestingly, Hayabusa2 could be extended to visit up to two different bodies in 2026 and 2031 thanks to remaining propellant. It may not be best geared for such encounters, but pretty cool nonetheless. Always put a little bit more juice in your probe tanks, kids!

>>12254475
What was the sample return mission that failed on reentry? I think there was a parachute failure.

>>12254634
Genesis.
https://en.wikipedia.org/wiki/Genesis_(spacecraft)#Fate_of_spacecraft_bus
It was ok though.

its pulled the arm back in and should be close to reestablishing orbit above Bennu. You might watch the DSN to see when the bit rate pops up and we get that sweet, sweet rock porn downloading.
https://eyes.nasa.gov/dsn/dsn.html
Although you should probably do something more productive while waiting instead, maybe go watch some anime or something?

>>12254703
It's back on the high gain now! Images are downloading at a blazingly fast 299 kb/s!

WHERE ARE THE GODDAMNED PICTURES

>>12255401
Not coming for another couple days

t. On Spacecraft Team

>>12255715
Depressing, but I can't expect instant gratification from deep fucking space all things considered. I look forward to closeups.

>>12255748
It's also operated by JHU APL and they only work some what normal hours.

>>12255769
It’s not. University of Arizona does their image processing.

>>12255335
wow didn't know of this live update site
nice catch anon

>>12255401
it takes a bit to download them at 300 kb/s anon

Does anybody know what format are the picture that are being sent? compressed JPEG or TIF or other?

>>12254173
But if this works out right, it could lead to us CHOOSING which rocks drop on us and where, either for mining, safety or warfare.

>>12254173
you're a fucking retard.
An asteroid undergoes irreversible chemical change while burning in the atmosphere. Plus now we know exactly where the sample has been in the last billion of years or so.

>>12254185
no you brainlet

uh bros why isn't the DSN downloading anything from Osirus Rex right now

Its morning, where are the pics?

>>12256216
It’s all down homie.
Let me tell you, the team knocked it out of the fucking park. ;^)

>>12255894
Varies. Most are PNG but there’ll probably be some some uncompressed GIFs and compressed JPEGs for different media. That’s how it was last time.

>>12254659
Genesis is also the (translated) name of the failed Israeli lunar landing last year.

>>12256651
no, what format does the spacecraft send the data back down in

>>12257583
Probably tiff or something equally wasteful knowing NASA and their legacy standards.

Native image format is FITS.
See https://arxiv.org/ftp/arxiv/papers/1704/1704.04531.pdf

>>12257788
>Image metadata is stored in a human-readable ASCII header. The information in this header is designed to calculate the byte offset of some information in the subsequent data unit to support direct access to the data cells. Each FITS file consists of one or more headers containing ASCII card images[a] that carry keyword/value pairs, interleaved between data blocks. The keyword/value pairs provide information such as size, origin, coordinates, binary data format, free-form comments, history of the data, and anything else the creator desires: while many keywords are reserved for FITS use, the standard allows arbitrary use of the rest of the name-space.

Reminds me of the old IFF file format in a way. One header to rule them all.

Hope the flight controllers are wearing decent attire.

>>12257864
???

>>12254193
Your fake pandemic has barely killed a million people so far.
Compare that to Spanish flu or Black Death and the populations affected by those.
The lockdowns and dancing nurses have probably killed more people than the flu itself.

>>12254460
This shit is why people don't believe in your fake space bullshit.

Sample mass measurement expected to be released on Monday.
