Re: "Why can't they make the Starliner work now"

Boeing acquired North American as part of the Rockwell sell off in 1996. Boeing acquired NAA, RocketDyne and Rockwell's defense electronics businesses.

So Boeing became the service point for the Space Shuttle :-)

Boeing is a shadow of its former self thanks to the bean-counters who set out to line their pockets, while producing rubbish product. During the Apollo era I don't think propellant valves would get stuck after so few duty cycles.

Seagate finds sets of two heads are cheaper than one in its new and very fast MACH.2 dual-actuator hard disks

Bubba Von Braun

Re: Is this new?

No not new at all.. had to think back to my NCR days, but Conner Peripherals "Chinook" drives. 3.5" SCSI more high throughput than capacity though.

It seems Seagate has resurrected/perfected the technology as they eventually bought Conner. Will be interesting to see what arrangement they have to interleave the data to get the additional capacity in the same surface area.

It is 60 years since the first cosmonaut reached orbit and 40 years since the Shuttle first left the launchpad

Bubba Von Braun

Ah when we took risks to achive great things.

I look back and see how we are so risk averse it actually inhibits more than it protects.

Great things were achieved by those prepared to take the risk, can you imagine SLS/Orion doing its lunar flight after just one test flight of the booster to earth orbit? Not now we will wait years/decades at the current snails pace.

But I do wonder if this has become a case of perfect being the enemy of good enough.

AU Downloads

Seems that NBN there is some traffic management going on in the NBN network affecting FS2020

A full day of frustration, and thought that the issue was with the cloud flare servers hosting the content for download. Nope a simple switch to VPN with an AU outfall point, and its downloading as fast as my FTTP can take it.

Annoying as the ISP claims not to be shaping the connection to the US via the VPN is taking a longer path, (ABB is only 3 hops) yet without the VPN I am getting at most 1 Mbps. On VPN 89 Mbps! All my other access/downloads/rdp etc from the US today has been fine.

So lesson here is try a VPN to avoid the traffic management that may be present either in your ISP or the NBN network.

The second one will be just how well will it perform without the VPN running when flying. time and testing will tell.

Fresh astro-underwear, anyone? Orbital shenanigans as Progress freighter has last-minute ISS docking wobble

Bubba Von Braun

Re: Only 3 hours?

The ISS is on an orbital inclination of 53 degrees. This is required to allow the Russians to play as their launch sites are further north than those available to NASA and ESA. When this was decided, it led to the program to reduce the Space Shuttles weight as it needed improved performance to be able to lift the payload to the required inclination. You will have all seen the pitch/roll well that is the important part of getting it on the right course. A note of trivia.. the OMS motors on the shuttle could only adjust its inclination by 3 degrees if you burn all of its available fuel.

The rest is a matter of orbital dynamics. In Demo2 case they were doing allot of checkout ahead of docking. Those who watched the approach and docking would have also noticed the series of checks done to confirm abort behaviors for docking.

So can you do a rapid ascent, yes, as long as the ISS is in the right place and you launch at the right time. Now if you had a shiny new ride I for one would like to take my time getting to where I needed to.

After 84 years, Japan's Olympus shutters its camera biz, flogs it to private equity – smartphones are just too good

Bubba Von Braun

Re: Olympus were special

Same here.. Started shooting Auto-racing as a teen with my Trip35, and got some shots that the then pro's were impressed (while shit caning the camera ;-)) Fond memories, and then when I re-entered in the Digital era think its was '99 got my hand on a little E100-RS. Talk about a wicked little camera.. optics were awesome for the size and MP of 1.8 well it limited you, but had this pre-capture system that removed the whole issue of shuttle/photographer lag, push the shutter button and the previous 5 frames are in the card for you at 20 FPS. Continued my investment with an E1 and then an E3, along with a decent collection of lens (50-500mm and lots in between). However I saw the writing on the wall just before the shift to micro 4/3rds.. Then it became a choice between Cannon/Nikon, the latter has won out and the D850 is a cherished family member.

And why do some of us think Olympus is done as a camera brand. You only have to look at what PE did to Kodak, Polaroid etc.. slash/burn and then whore the brand around.

Olympus will always have a special place its where I started and the lessons learned have served me well.

Apart from the morons who responded to why they opened the attachment "I just had to know who loved me.." was a favorite. One of the later variants was I have billed your credit card for $$$ (cant recall the amount) for an airline ticket.

Scarier still was the inability of AV software to come up with a signature that would catch it. Those variants all shared common code.. yet S$ couldn't come up with a decent signature file for nearly a week.

You can easily secure America's e-voting systems tomorrow. Use paper – Bruce Schneier

Bubba Von Braun

Paper works. Having been an election official here in AU, I have been part of the process.

To the point raised slipping in extra ballots wont work. The polling place has say 3000 ballots issued to it. We need to account for them this is done throughout the day. At close of voting the ballot boxes are opened in by voting officials, and counted in-front of scrutineers from the various candidates.

Once tallied the results are phoned through and all the ballots and materials are packaged and sealed, delivered to the returning office for that district. These ballots are counted again at least twice in the following weeks to verify the counts.

Its this accounting that picked up 1300 missing senate ballot papers in WA. And to ensure integrity of the vote, a fresh senate election was held for that state.

The key difference between Australia and the USA, is we have a totally independent organization for managing boundaries, enrollments, the count. So no gerrymandering, its all based on population and voting is mandatory. If an official shows the slights bent/bias they would be removed very quickly.

All done with pencil and paper

Messr Kraft and Kranz are the reason I do what I do today in amateur rocketry. I always thought mission control was the cool place to be.

I recall a quote (cant recall where) but when asked about the EVA what was the most important thing Armstrong and Aldrin do. His response was to "Get off there and come home"

A great loss, but spaceflight stands on his shoulders, for his leadership in mission planning, management and flight control.

Oh little trivia.. Kraft never saw a manned launch in person ever!

We don't know whether 737 Max MCAS update is coming or Boeing: Anti-stall safety fix delayed

Bubba Von Braun

Re: Question for the experts

The engines on the 737 MAX series were moved slightly forward and up to maintain the necessary ground clearance. (ever wondered why the engines have flatted bottoms on the nacelle)

The issue as you point out is the increase in air flowing below the wing especially in take-off/climb can cause a pitch-up moment leading to a stall.

MCAS was developed to counter this issue, however if the reports are correct and there is only one AOA sensor feeding the MCAS system, then its design is fatally flawed. There are two AOA sensors on the 737 MAX and integrating them should resolve any AOA sensor failure. Why they didnt probably cost/schedule pressures.

Also seems Boing's design philosophy has been to let pilot inputs over-rule the flight computer. Seems that has changed with MCAS or its truly a bug in resetting the override count. Whats worse is that this wasn't called out.

Re: Comparison

You miss a key point..

While the president can run on a series of "promises" so do the elected officials from that other branch of government... The Congress (House of Reps/Senate)

After enduring crown rule, the founding fathers wanted to make certain that no one arm was all powerful ruling over the people. Of the three arms of Government, (Congress, Executive Branch and the Judiciary) The executive branch is probably the weakest.

In this case POTUS still needs to obtain the support from the Congress, and vice/versa for policies spending etc. One could argue that POTUS is the weaker here, as the Congress can override a Veto by the President with a super-majority.

A presidential election is not a blank check..

Re: mono-propellant...

Nope your right you may wear your pedant badge with pride..

HTP provides one of two parts of the system. This is a hybrid.. using HTP for the oxidizer and synthetic rubber for a fuel in a classic hybrid design. Describing this as a "mono-propellant" is not correct.

To quote for @amis reference.. "When used with a suitable catalyst, HTP can be used as a mono-propellant, or with a separate fuel as a bi-propellant." in this case the team are referencing its using a rubber fuel element.. and hence is not a mono-propellant but a bi-propellant hybrid.

With good reason, the thrust generated in the HTP steam engine will be substantially less that that generated in a hybrid.

If Fitbit had half a brain, (and looking at the financials they don't) why not breath life into the pebble products you acquired, or is this a case of not invented here? Though given those financials, I suspect they will go the way others, but not seen as purveyors of good solutions but sharks acquiring and dismembering great idea's

Great Advice

Good common sense advice, after all its code of a form, and should be subject to reasonable change controls.

The same goes for SysAdmins who Google/Technet/Spiceworks etc solutions. I always have my admins verify a solution before they try and implement it. How many times have we had a user or a Help Desk guy grab a solution from a Google search try it and make a situation a whole lot worse.

Key thing is peer review/support. Its a whole lot easier to get a colleague to cross-check what your planning to do, rather than tie up the entire department cleaning up the mess created by that "quick fix" you found.

Ah but the convenience, to allow an engineer diagnose faults in all of the aircraft no pesky cables just walk up connect and go.

Re: Double vacuum

Apollo capsules were once in space pressurized to 5psi pure oxygen. For the on-pad and initial climb to orbit it was a two gas oxygen nitrogen then was bled down from 14psi at sea level, to 5 psi pure O2

Oldest flying 747 finally grounded, 47 years after first flight

Bubba Von Braun

Re: A venerable workhorse

Same way they tested them in the beginning, lots of ground testing, taxi testing and then flight test. 747 had a wicked problem with the initial P&W JT9D-3's as the engine case deformed and caused blades to touch the case, never good thing. Fix was a revised engine mount.

Most twins especially the 767/777 have great single engine performance. Given your doing flight test in a lightly loaded aircraft I would expect a few more air-frames kicking around.
