I think its a bit optimistic the say a hybrid design is 'scale free'. Neither electric motors nor batteries scale up well. It get progressively more difficult to get their generated heat out the bigger they get.

I can't possibly imagine that that design will ever be practical.

Nice as a technical exercise though.

When I worked in an R&D organization, we had a saying:" There are no bad ideas, just ideas" Something might come out of it. Maybe nothing like you see here but it might spawn another idea.

I'm just wondering what would happen if 1 motor or esc packs up.An expensive re-kit?
I'm also thinking some considerable computer power could be required to stabilize the thing.
I suppose those poor guys at NASA have to justify their jobs somehow.

Yeah but NoBama finally realized his mistake and did a U-Turn. He took the advice of Russians US Diplomat and bought NASA a trampoline to launch USA astronauts into space.

LOL. Seriously though I work on Langley AFB and the NASA Langley research center shares land with us. This where the Mercury, Gemin, and Apollo programs all got their legs. Heck I have have to take Commander Shepard Blvd by NASA to get to work.

Once in awhile I will cut across NASA just to be nosy as I have access to that side as well as a fire fighter. It is like a ghost town, buildings boarded up, equipment we spent billions of dollars on just sitting around rusting.

It is truly sad.

I suspect the crane is more of a safety line, there to save the model if it loses lift (or its mind.)

The article states:

"For now, Greased Lightning only has a wingspan of 10 feet (3 meters), and its first test flight (National Aviation Day, August 19) was tethered. Untethered flights are planned for later in the year — and hopefully we’ll then get some awesome videos of it flying around, too"

For those who missed the "printed" text....rather than "only look at the pretty pictures".......lol

Better not let the FAA catch them. On a more serious note, it is sad that where the U.S. was in the forefront with space tech. Looks like we're in the basement now.

That was the whole reason behind the tether! Not free flying, so no one was getting paid to 'fly' anything and such.

RR I am not big on NASA. I am in my mid 50's and was 12 when we landed on the Moon. As a kid I was wildly interested in the Space Program. One thing most people are not aware of, well anyone under 50 anyway, is the space program has paid for itself many times over, and just about all the technology and advanced materials we take for granted today comes from the space programs.

Makes me no difference if it comes from the private or public sector as long as we stay out in front of it taking the lead. As it has proven to be an excellent investment and nothing has changed to change that fact.

One thing I do know is the government owns most all the land to make launches from, and frankly the USA is at a bit of a disadvantage. The equator is the best launch site and takes the least amount of energy to put something into orbit. Cape Canaveral is the furthest point south we can launch from in the USA unless you want to move it to Key West. That brings up a thought. Invade Cuba and take over.

Did you watch the video of the unveiling of the Dragon 2 spacecraft? The wow just went back into the space programs. Yes, we need to invade Cuba. First, send in McDonalds, Walmart, Target, an Amazon distribution center and an automobile manufacturer to soften them up and then whip Spacex on 'em.

No reason for that land to be a poverty stricken wasteland. Shoot some Old Navy stores, a Hobby King warehouse, several dozen golf courses, Publix Grocery stores and that should mop up the stragglers.

It's the new kind of invasion strategy!

No but I seen the video of their launch yesterday here in TX of SpaceX Falcon 9 Reusable that blew up for unknown reasons.

Video here

Not sure any of this is really new. Every rocket and missile is built by contractors. NASA does not build anything. They just run the missions. SpaceX is no different than say Lockheed Martin or Boeing Aircraft.

"Not sure any of this is really new. Every rocket and missile is built by contractors. NASA does not build anything. They just run the missions. SpaceX is no different than say Lockheed Martin or Boeing Aircraft."
Ya....kinda knew that already.......
"Smartest move NASA ever made. Private industry's have more flexibility, resources, intellectual property/facility and funding. It's really nothing new in the technical world.....more than 90% of all advancements (since 1960) made in NASA progams have been designed/developed/manufactured/tested and supported by out-source private industry and intelligence..... either contracted or direct hire into government programs (tax supported).......... weapons made for mass destruction or surveillance are prime examples.

Sooooo........no weeping here for NASA, today It's just a label. The real advancements are made with private $$$....our tax dollars, more often than not, just "kick start" a program.....to keep it transparent".

"......this thread is starting to smell bad,
bubsteve"

Couldn't agree more.....there's always someone "lifting a leg over a hydrant" in almost every thread topic.....LOL.....

I understand. No having fun. Understandable rule. Make fun of those having fun. Even more understandable. Excuse me for being inappropriate.

There's a big difference between Spacex and Boeing. Spacex is an entrepreneurial organization. Its founder, Elon Musk, developed Spacex as the first privately funded organization to conduct the research, build and fly a liquid fueled rocket to orbit in 2008, "the first privately funded company to successfully launch (by Falcon 9), orbit and recover a spacecraft (Dragon) (9 December 2010); the first private company to send a spacecraft (Dragon) to the International Space Station[5] (25 May 2012); and the first private company to send a satellite into geosynchronous orbit (3 December 2013).

In order to control quality and costs, SpaceX designs, tests and fabricates the majority of its components in-house, including the Merlin, Kestrel, and Draco rocket engines used on the Falcon launch vehicles and the Dragon spacecraft. This has allowed SpaceX to offer one of the lowest launch prices in the industry and to significantly reduce conventional rocket development time. "

Spacex is fundamentally different from the grandfather aerospace companies. Spacex does its work, presents a product and then secures contracts. Because of the way it operates it can accomplish what NASA and its dinosaur contractors cannot and will not do.

According to The Washington Post in an article well worth your time to read: "Traditional "cost-plus" contracts limited the incentives to keep costs down. The government owned the spaceships and rockets. With the new, commercial contracts, the private companies assume more risk and put more of their own money into the projects. They design and build their spaceships and rockets, with NASA hovering in the background as a customer, not as a supervisor."

Spacex was formed in 2002 in part with the purpose of taking man to Mars. The National Research Council says that NASA/Boeing Space Launch System (SLS) can't get us there. I've already posted the description of SLS as a loose amalgamation of leftover political pork projects. New Space, those entrepreneurial companies privately funded for the purpose of limiting cost while using unpetrified imagination and energy, will be our road forward. The politicians will fight it. After all, the highest and best use of the federal piggy bank is to spend the money to get reelected, and pork projects do that well. But we can no longer afford their inherent wastage of money, their parasitic reliance on their political benefactors, their stultifying lack of imagination and innovation.

Use your own judgment. Watch the video of the unveiling of the Dragon 2 spacecraft and think to yourself, "has any government space program craft ever looked like that on the inside? Has any spacecraft in history had the landing capability to descend in your back yard? Has any spacecraft ever had the articulated, fold away instrumentation system that didn't take up most of the interior space of the capsule?" This is something new. This is what a 21st century spacecraft should look like and be able to do. It didn't come from Boeing. There are good reasons for that.

Claiming that New Space is fundamentally the same as Old Space is simply wrong and shortsighted. It's why we haven't returned to the moon since I was 18. It's why we send a dilapidated, unsafe space truck to very low Earth orbit for 30 years and pretended it was a space program. It's time to get the fossils off the main exhibition hall floor and replace 'em with people who have the right stuff.

By the way, in 1968, standing on Daytona Beach, I watched a Saturn V self-destruct. It was a full-blown launch of the entire man-rated Saturn V system with all stages of boosters and spacecraft involved. There have been plenty of traditional NASA rockets that failed. The Spacex explosion was only a test of the first stage only, attempting a vertical landing on its tail, something NASA has never even tried to do. You can't take a test flight explosion and extrapolate it into the incompetency of Spacex. That's patently silly.
