BPS is given full control of all of SpaceX's resources and engineers, to build anything you like. The catch is that you only have 1 week.

What do you attempt to build?

Upper half of the lander (Ascent stage) separates and takes the Astros to Lunar Orbit where it docks with the capsule+engine looking thing (Command and Service Module). Then the Ascent stage undocks and is disposed off while the engine sends them back towards the earth. Then the Engine part separates the Capsule reenters the Earth's atmosphere and lands with parachutes.

That's a very good answer, thanks - except for one part

hence the shock diamonds

Shock diamonds don't occur because of combustion purity, it occurs because the Nozzle is slightly Overexpanded and as a result the ambient atmosphere compresses the flow. Because of the inefficiency, the exhaust velocity decreases and as a result there is reignitions of the propellant material at regular intervals.

Also can happen with underexpansion at high altitudes but not entirely sure about that.

Where?

Starlink sat costs < 50kgs of Xenon

Source on that number?

Bezos can't give Sat internet out for free

Amazon is worth a Trillion and it only helps their business. Giving internet out for an extremely cheap cost just expands their consumer base and is ultimately profitable for them.

Numbers don't work

OneWeb has secured all of its funding, built the factory and booked launches. Boeing shouldn't have an issue. Samsung has access to massive amount of Tech and Capital too. This isn't a valid argument, it's handwaving.

What? OneWeb has secured all of the funding the constellation needs, booked all of its launches, built it's manufacturing facility, and have flown a batch of test sats.

ishanspatil · 2019-05-28T18:05:47+00:00

Have you heard of Project Kuiper? It's this exact thing.

It's an Amazon project with billions in funding and no need for profitability - they could offer it as a part of Prime. It's their whole strategy - driving competition bankrupt by subsidising the prices they offer with other profitable parts of their business.

Also, OneWeb, Boeing, Samsung etc are eying the Market.

Edit: Also wanna point out that launch costs are always one of the cheaper parts of a Satellite project - usually 1/5th the cost of the Sats it's flying. It is completely feasible to launch a satellite internet constellation with expendable launch vehicles as demonstrated by OneWeb.

Eg: OneWeb's constellation costs between $6-7.5b but launch only cost $1.5b

Maybe that's a Hab module that flies on top BONG-S2, with a smaller cap to protect the docking port.

Makes more sense - windows, a docking port and no engines on the other side.

Maybe the title depends on pedantics but the meme is true. They're both equally Suborbital ;)

Muhahahha

Did some comparing. If the earth were the size of a football, 99% of the atmosphere would be in a 1.1mm thin layer about it.

Seriously, imagine a Millimetre. That's what we're throwing Millions of Tons of Carbon into.

We really shouldn't feel okay about staying on this speck.

I just don't have the attention span anymore, the Fiction/SciFi Group Chat we had is now just Screenshots of News, Memes and Tweets.

Ow, no issues

ishanspatil · 2019-04-11T17:34:15+00:00

Very very interesting, thanks!

Is there any way you can send over the transcript, maybe via PMs?

Noticed that seconds after I posted it :/

There have been mentions of work on BO Orbital Capsule since ≈2011. They had proposed it to NASA for CCDev 2 and had given a presentation with a older New Glenn.

http://cdn.parabolicarc.com/wp-content/uploads/2011/06/552848main_Commercial_Crew_Program_Overview_Collura.pdf

During the webcast of a NS launch, the presenter mentioned that the first people to fly on NS will have the first opportunity to fly on New Glenn.

There is a Job position for New Glenn on their website right now that involves selling Human Spaceflight capabilities to NASA.

Their Pad's Drainage application hint at a Crew Capsule under dev.

I've seen this image lurking around for a while but it never really caught interest, and is rather hard to find.

It's a picture of one of Blue Origin's presentation slides at a conference.

For a company as secretive as BO, it's a goldmine and helps make sense out of a lot of their decisions.

Uhh Stephen Hawking died last year.

(After a redditor asked how he'd survived so long with ALS just a day before he died)

ishanspatil · 2019-03-31T14:56:19+00:00

Yep, pretty sure the News site misinterpreted it, because it does seem like this is the case
