Blue Origin thread.

Recommended Posts

The New Glenn rocket is set to launch no earlier than Sunday, Jan. 12 from Launch Complex 36 at Florida's Cape Canaveral Space Force Station.

 

The three-hour launch window will open at 1 a.m.

 

The launch was originally scheduled for Friday at the same time, but was postponed due to "high sea state in the Atlantic."

... 

The primary payload for NG-1 is the Blue Ring Pathfinder, which will undergo tests of its core flight systems, ground operations and overall capabilities.

 

In addition, the company will try to land its booster offshore in an attempt to test its reusability.

I’m still not a fan of those narrow stance professor gadget landing legs.  Especially not for a barge landing.  We’ve all seen the F9s with their wide stance get little tippy during and just after landing before getting secured to the barge.  Then there are the rough seas out there lately.

I’m guessing they will approach the bullseye on the barge with high probability, but stability during and after landing is a crap shoot

Mechanically speaking, for an object to tip over, the vertical projection of its centre of mass to the surface on which it rests must move beyond the polygon defined by its contact points on that surface. Since an empty landed stage is very bottom-heavy, because all the heavy parts are at the bottom of the rocket, it takes more to tip it over than it might appear.  The centre of mass may be approximately at the point of the feather in the blue logo, and then the landing legs may be more than sufficient to keep it upright, even at a tilt.

Don’t forget any uncanceled relative horizontal velocity when the first leg touches the deck that is pitching, heaving, and translating on the sea and the effects of wind forces on the lighter weight upper portion of the booster.

 I’m also wondering about the mass difference up top between grid fins and the canards.

Anyway, success possible, excitement guaranteed, right?

I care about it, probably a few people here too who care. This is the thread for Blue Origin, there's at least 1 person here who cares.

Actually that gives me an idea...

How much of a refuellable people-carrier could this lift? We know BO is investigating propellant depots. A modified Dreamchaser (or something entirely new) could continue the tourism business and cart people up to Orbital Reef. Maybe to the moon with refuelling.

Oh, we care. The more, the merrier. Not putting too many eggs in one basket. Competition/backup. Yadda yadda yadda. As long as they can get enough of a flight rate to be useful...

Don't get me wrong - I care about the big guy; but not how many Billionaire Tourist Capsules it can pack.

That's my beef.  The "so many truckloads to space" part I like.  P-Heads?  Nope.

Ah, my bad. I misread/ took the wrong meaning
