Re: Blue Origin

Not intending to disrupt the previous posts, but here is an article on the subject:
https://www.space.com/blue-origin-blue- … ained.html
Quote: (The claimed specs on this look really good compared to the other mentioned lander(s))

For comparison, the Apollo lunar modules that carried astronauts to the moon in the late 1960s and early 1970s were 23 feet tall and weighed 4.7 tons (4.3 metric tons) without propellant. Lockheed Martin's proposed lunar lander is a bit bigger and heavier. That lander, which would also use LH2 and LOX for propellant and has yet to receive a name, would be about 46 feet (14 m) tall. Even with an empty fuel tank, the lander would weigh 24 tons (22 metric tons) — more than seven times the dry weight of Blue Moon. When the Lockheed Martin lander's fuel tank is filled, the module will weigh a whopping 68 tons (62 metric tons).
Blue Moon may look smaller than Lockheed's lander, but it will have a bigger payload capacity. It will be able to deliver about 4 tons' (3.6 metric tons) worth of payloads to the lunar surface, compared with 1.1 tons (1 metric ton) for Lockheed's lander. A "stretched tank" variant of Blue Moon will be able to carry up to 7.2 tons (6.5 metric tons), including an added ascent stage — and some additional fuel — that would allow astronauts to visit the surface of the moon.

A fair amount of fun.

I am under the impression that the New Glen 1st stage will use BE4 engines (Methane/Oxygen), and the upper stage will use BE3-U engines(Hydrogen/Oxygen).  For the three stage version, I don't know what engines would be used for the middle stage.

I believe that the BE5 is being developed for New Armstrong, guessing Methane/Oxygen.  But that leaves me to wonder if there is to be a BE6 engine, since Blue Moon is to use the BE7 (Hydrogen/Oxygen) engine.  A mystery.  Maybe they are just funning us on that.

No clues here about Nitrogen.

One very interesting notion about Blue Origins that may still be planned is to build a lunar base from delivered modules by automation, before people even show up.  The idea some time back is that the modules would apparently be "Plugged" together by automation.

Done.

The arrays provide 1,500 to 2,000 Watts of power peaking up to 4,000 Watts. Two Power Buses are part of Dragon’s electrical system, providing 120 VDV and 28 VDC respectively. 4 redundant Lithium-Polymer Batteries provide power during orbital night, ascent and re-entry.

So 2 things that can go from the capsule mass numbers are the parachutes system and the PICA heatshield as these will not be part of Dragon modified for Lunar exploration.

I have read the mass of the heat sheild is in the 2,000kg - 3,000 kg range....
Still looking for the parachute numbers....

After we have the modified numbers for what we would call the ascent stage then we can work on the truck to make it into the descent stage.....

Re: Blue Origin

Well, I am guessing that SpaceX will also go big on the Moon.  But of course they may likely not be able to refuel from the Moon, except of course Oxygen.  That would be big after all.

Still, due to your post, I have realized that it could be possible that Blue Origin based boosters with BE7 engines could be partnered with Starship.  Starship is well equipped to get to LEO, and Low Martian Orbit as well.

But used upper stages of New Glen, might be recruited to be a tug.  (Of course at this time they use BE3-U engines.

So, in this notion at first water from the Moon could be split into Hydrogen and Oxygen both at LEO, and somewhere near the Moon.  And a starship fueled with Methane only in LEO, could be tugged to a lunar orbital position using the tug I mentioned.  There it could be loaded with Oxygen from the Moon.  Then the tug mentioned if needed could position the Starship to a very high Earth orbit.  The Starship could launch from there.  I have information that such a start would allow a 30-40 day trip to Mars.  I cannot vouch for that being true.  However it does seem true that if you have a powerful enough launch method, you could do that.

At first the Hydrogen from the Moon.  Later Hydrogen from NEO's, possibly also Oxygen, but perhaps much Oxygen from the Moon.

FYI, I understand that New Armstrong while a period of time off, will be roughly equivalent to the power of SuperHeavy/Starship.

It is being worked on but I believe it is a fair distance off.

Done.

Re: Blue Origin

Digipen student project heading to space on Blue Origin's New Shepard rocket

The recent advances in low-cost access to space like Blue Origin's New Shepard are facilitating these types of student projects. Thomas and Solorzano plan for more DigiPen sensors systems to be launched on rockets, including (potentially) instruments on small satellites - known as CubeSats - that will stay in orbit.

Low cost is the way going forward to get more than the rich and governments to orbit for sure.

Re: Blue Origin

New Shepard is what Blue Origin is flying,  and it is strictly suborbital.  Burnout is several dozen thousand feet at about Mach 3 (roughly 1 km/s upward).  It coasts ballistically to a zero-velocity apogee at about 60-90 km altitude,  then falls back.  Blue Origin has chosen to recover the booster rocket separately from the manned capsule. 

The orbital rocket New Glenn is still nothing but a paper design at this time.  It's quite a bit bigger than New Shephard,  and if memory serves,  two stages.  They don't plan to recover the second stage,  as far as I know.

Re: Blue Origin

Blue Origin beat Space X to the recoverable stage landing. Ever since I keep a beady eye on what they are up to. Essentially they have access to unlimited funds via Bezos. In case you're wondering, Bezos's net worth is $145 billion...

They can afford to be relaxed and unshowy. They might yet surprise us.

Bezos's obsession though is quite different from Musk's.  Whereas Musk wants to transfer humanity to another planet, Bezos wants us to create huge artificial worlds in space.  So I think Bezos's ambitions are "closer to home".

Re: Blue Origin

For Mark Friedenbach re #37

Your question of SpaceNut caught my eye, so I decided to ask Mr. Google about DigiPen.

Patents
Gaming machine system having a gesture-sensing mechanism
Abstract
A gaming machine has a processor for conducting a wagering game on the gaming machine and a gesture-sensing mechanism. The gesture-sensing mechanism can be used for providing various inputs. For example, the gesture-sensing mechanism provides player inputs that select certain options during operation of the game. The gesture-sensing mechanism may further distinguish between a first gesture indicative of a first player input and a second gesture indicative of a second player input. Or, the gesture-sensing mechanism provides player inputs in response to a physical action by a player that relates to a theme of the gaming machine. Alternatively or additionally, the gaming machine may include a microphone in communication with the processor. The microphone receives player inputs in the form of acoustic signals.

I wonder if the cube sat might be able to create video suitable for inclusion in a video game?

Or perhaps there is an application for gesture interpretation in the real world, as well as in the game world. 

It would be interesting if someone in the forum readership could investigate and report back.

Re: Blue Origin

Re post 36:

McDonnell-Douglas beat Blue Origin to the recoverable stage landing,  if you consider their DC-X vehicle that flew several years ago. 

But there's recoverable stage landings and there's recoverable stage landings.  Here's what I mean by that:

DC-X landed from a few hundred meters altitude and a very subsonic speed.  Blue Origin landed their New Shepard stage from a few km altitude at about 1 km/s (Mach 3) speeds.  Spacex lands their Falcon cores from dozens of km altitude and about 3 km/s (near Mach 10) speeds. 

So,  which outfit has accomplished the more difficult mission?  (There's a whale of a lot more to it than just surviving a rocket touchdown.)

Re: Blue Origin

For SpaceNut re #43

The article you cited was 31 hours old .... since then the bidding has stopped at $28 million

Jeff Bezos' space venture Blue Origin auctioned off a seat on its upcoming first crewed spaceflight on Saturday for $28 million. The winning bidder, whose name wasn't released, will fly to the edge of space with the Amazon founder and his brother Mark on Blue Origin's New Shepard rocket scheduled to launch on July 20.

For someone like that, the $28 million is pocket change.

Re: Blue Origin

This is primarily for kbd512 but it may be of interest to others ....

Per Google ...

Bezos' Blue Origin aerospace company's rocket launch site is in a secluded desert area near Van Horn, a tiny town of about 1,800 people located about 120 miles southeast of El Paso.4 days ago

Tiny Van Horn, Texas, gears up for international fame with Jeff ...https://www.dallasnews.com › Business › Technology

Tradition (such as it is) puts Starfleet Academy in San Francisco.

However, the present rivalry between Texas and California suggests (to me at least) that Texas might be a suitable location for Starfleet Academy, where you can put your candidates through all the pushups you consider necessary.

I'm interested in Starbase Academy, and would look for support from Elon Musk ** if ** the focus of the school is tuned to his needs.

Jeff Bezos ** might ** be interested in sponsoring the officer training program at Starfleet Academy.

The Space Force might be interested in both schools and willing to put some muscle into making them happen.

Re: Blue Origin

The not a contest is happening in the news media between Bezos ship and Bransons as they both are ready to take a flight on the ships that they made to the edge of space.

How Richard Branson will ride own rocket to space

with Bezos coming next week making a bit higher on its flight
Jeff Bezos' — the multi-billionaire and his brother will join Blue Origin's first suborbital tourist flight that's scheduled for a July 20th launch.

Blue Origin throws shade at Virgin Galactic before Richard Branson's flight

75bacb40-e163-11eb-bef3-3526ea447d76

The Kármán line is the boundary between the Earth's atmosphere and outer space as set by the Fédération Aéronautique International. It's defined as 100 kilometers or 62 miles above sea level, and according to Blue Origin, it's what "96 percent of the world's population" recognizes as the beginning of outer space. Blue Origin plans to offer customers 10 minutes of flight with an altitude that reaches the Kármán line. Meanwhile, Virgin Galactic's website says its flights will soar at "nearly" 300,000 feet (57 miles) in altitude. That doesn't quite reach the Kármán line, though that's still higher than what NASA and the US government defines as the beginning of space (50 miles above sea level).
