/sci/ - Science & Math

A press conference for SpaceIL is going on right now. I'll post updates

-want to convince kids to go to STEM fields
-met more than a million kids through talks with volunteers - if you study science and engineering, you too can build a spaceship etc etc
-spaceIL was established in 2011; non-profit entity
-2015 full scale development was started
-main mission is to “enthusiast the kids”
-unique mission: Israel is a very small country, will be 4th country to soft-land on the moon
-first non government mission to the moon
-first moon mission to use a commercial launch
-2.3m diameter
-total program cost $100,000,000 including launch service
-7 weeks to reach the moon
-5 communication stations
-science: magnometer, laser reflector
-S5 is right beneath the lander, which sits onto of PSN-IV
-10 different manuvers

onboard:
engraved plate of Am Yisrael Chai
tiny engraved entire text of the Torah/Bible
Israeli flag

interesting how we didn’t know which core it was until the press kit came out. I wouldn’t have guessed they’d use a twice flown one. But, that’s the whole point of block 5. Wonder when the first fourth flight will be

>>10404736
soon, hopefully

>>10404736
Also, no mention of fairing catch. But Steve is in position

OCISLY ready for action

>>10405629
how does this thing work exactly?

>>10405676
It slides under the booster, grabs it and locks it into place so it doesn't tip over due to rough seas.

>>10405684
>>10405676
not tipping over, that's a non-issue. The problem is it slides around the deck.

I didn't even want to take that class, but I had to so I can stay at full time.

>>10405971

>>10405971
Eh, launches are so common now you can afford to miss one. A launch came up once while I was on a train with no data so I couldn’t stream it.

The hopper fairing 2.0 is currently being built

>Polished steel
Glad they gave up on the foil

>>10406135
>>10406143
is it gonna fall over for our amusement again?

It’s amazing how the 3rd reflight of a booster is just a “meh” sort of thing nowadays

>>10406214
that's just how technological advancements are. once they become boring, that's when you know it's been perfected.

>>10406212
It looks a lot sturdier than fairing 1.0, less foil and more steel.

>>10406198
Polished or actual 300-stainless?

>>10406214
2nd reflight, 3rd flight.
Get your language right.

Mr Steven bailed on fairing recovery?

>>10406135
>>10406143
they're using much larger sheets of the stuff this time

>>10406214
that's because a 5th flight has already been done

>>10406295
Just not by an orbital class booster.

meanwhile, Hayabusa2 is landing!

>>10406437
sad bit of trivia, when Columbia failed due to the internal suture being eaten by the hot plasma, it was just then exiting the point of re-entry that had forces high enough to destroy the metal frame. It could have survived if the burn-though happened a few minutes later. Hell, there was even a different shuttle flight where a tile failed, but it was luckily right under a beefy piece of metal which could take on reentry

>Plebs who close stream after Stage 1 landing

>>10406783
They will show it when they get the footage off the drone ship. Downlink is always scattered from the vibrations during landing.

>>10406790
no boostback burn. Lofted entry on high speed of the core; you could see plasma before entry burn and a fuckton of sparks after. hot as fuck.

Also, waves

kek

>>10406790
conditions weren't challenging, they were just saying that so they wouldn't look bad if it failed

This was a triumph.
I'm making a note here: huge success. It's hard to overstate my satisfaction.

shit, looks like the booster toppled over into the sea

>>10406816
They should ditch that shit and put some Vivaldi on instead.

>>10406821
AHAHAHAHAHHAAA MUSKRATS CANT EVEN SECURE T LONG AS FUCK BOOSTER SO IT DOESN'T FALL FROM THE SHIP

just heard that the booster fell over and exploded before it could be secured.

>>10406821
how long until a human can come into contact bolting it to the boat?

>>10406823
Is SpaceX finished?

>>10406825
IIRC they've got that little roomba thing that's supposed to come out and grab onto the booster after landing. They might not have been able to deploy it in time.

>>10406825
The roomba is supposed to clamp on the booster legs and weld itself to the deck

>>10406825
They use this >>10405629

Are you guys just trolling because nobody in my twitter feed is mentioning it toppling over?...

>>10406821
source?

>>10406819
Already did! Projectile fired too.

>>10406821
>>10406824
I'm calling bullshit, the center of gravity is so slow the only way it could have toppled over is if it somehow slides off the deck.

If not...

>>10406822
>not the planets

>Launch in darkness of night
>Booster "tipped over" into ocean
>No US payload

How do we know this launch actually happened?

>>10406839
>No US payload
didn't it have a classified something for the air force in addition to the other stuff?

If you think about how rough a no boostback trajectory is for the Falcon, even with SpaceX's knowledge of TPS and re-entry. Think about how rough it's going to be on a New Glenn, because Blue Origin plan to do this every launch. Doesn't seem very pragmatic for reusability...

>>10406843
It had a US airforce small sat designed for spying on other countries' GEO military sats.

>>10406849
falcon 9 doesn't have wings, a wide body, or fins

>>10406849
non-boostbacks are actualy easier on the payload. Thus why they’re not doing them for manned dragon 2 missions, even though the margin is there. The issue lies with the ocean moving the ASDS around. BO’s solution is to have Stena freighter moving during the landing, which gives them greater list control

good orbit. also, 4th flight of B1048 confirmed

Can anybody make webms of the two deployments?
Or will I be able to rewatch this later?

>>10407011
Good point.

>>10407065
They should blow up that one with the jammed hydrolic lines.
Makes no sense to blow up one that landed proper if they have a servicable if damaged, one to use instead.

>>10407059
well aren't you special

>>10407125
They want specific abort conditions to be met. Plus, the increase of a pad RUD chance isn't worth it. That core was pretty damaged, despite what Elon initially said about it being good to fly later.

This is NASA comm crew stuff we're talking about here. They don't want any more delays

>>10407133
>>10407049

They want to start some space baby boom phenomenon in Israel to get the youth interested in the subject and study the field further.

1. Test lasted for 8.5 seconds.
2. Test abort was called at 7.9-8 seconds due to "an abnormally loud high pitch whining sound".
3. Between 8-8.5 seconds raptor reduced power successfully to 85% ahead of shutdown however damage was already occurring.
4. At 8.5 seconds engine shutdown.
5. Raptor did not RUD as first thought or at least not completely or violently. Engine was taken to an on-site shop and dis-assembled to some extent.

Sounded like the problem was either in the LOPB or LOTP bearings or was excessive back pressure on the LOTP. Given the nature of raptor's design these would have been some of the highest pressure areas in this test.
Supposedly, in the 8 seconds of run time prior to power reduction raptor produced an insane amount of thrust. On the order of 320mt or higher, the number 380mt of thrust was mentioned but i personally doubt that Supposedly, this test was contrived to run the engine beyond design limits to "see what it does".

That translates into roughly 380bar cp and 1000+ in otp

>>10407984
So were they literally attempting to push the limits?

>>10407984
i want vids to be quite honest

>>10407992
It apparently produced around 3.2 MN of thrust. I don't see how that's possible but if it is, Raptor produced nearly a mega-newton more thrust than a BE-4 (2.4MN) can at full throttle...

>>10408086
Scratch that, it was 320 bar chamber pressure and over 2.6MN...

>>10408101
the chart Elon sharesd doesn’t agree...?

>>10408110
It was an older test.Later they tested SN1 to it's limits

>>10407984
Could they have learned something from previous tests that meant following engines must be different, meaning they could push this one to destruction as it wouldn't be useful on the hopper? Running it at 300+ bar pressure just after few flares seems strange otherwise.
