You'd have to constantly give the anchor orbital correction boosts to keep it a given (not constantly increasing) distance behind the ground station, or else over time you'd start a winding-up process like winding up the string of a yo-yo, which would also pull the orbital anchor closer to the...

Well, that much is absolutely true. Carbon nanotubes with great tensile/weight ratios will be useful in lots of other stuff.

a "space elevator" will never ever work because if you had a cable or other connective device attached to some kind of anchor object, even assuming in theory the ground anchor was placed precisely on the equator and the orbital anchor was in a precisely geosynchronous orbit and the problems of...

I cut parachutes out of dollar store plastic tablecloths, available in a bunch of colors: https://www.familydollar.com/hot-pink-plastic-tablecover/FD1301969?gclid=CjwKCAiAxP2eBhBiEiwA5puhNcLZr7ZHN5XoDyy81t2NbVYz0aX99DC5Ev0wui5wkaTrFh52-q8AiBoCCHgQAvD_BwE Usually there's plenty of scraps left...

Depending where it hit, something the size of a BB would probably wreck it too.

Oh, it's on now. I bet the season ending episode of Picard will be broadcast live from the ISS, courtesy of SpaceX.

I have about 300 motors mostly dated from the 1970s and a couple hundred of newer vintage. I've noticed no particular increase in CATO rates for the older motors. I was able to pick them up in a carton for $50 for 75 diamond packs when a toy store cleared out its old basement. I have a handful...

Ok, I never would have entered any altitude contests but it flew fine. I flew it a dozen times or so before I took a 19-year sabbatical from rocketry.

Years and years ago (about 50) i made a Bizarro Bertha out of a wrapping paper tube, a plastic nose cone I got Easter Candy in, with fins out of scrap balsa and the motor mount out of a couple semi demolished BT-20 rockets. All put together the parts cost me about 50 cents. Everything fit pretty...

Also the size of standard paper towel rolls. And a 3-motor cluster of BT-20 (18mm) fits just right.

Nothing like jumping back into a thread after a brief 7-year hiatus! :rolleyes::oops::rolleyes: one thing that's definitely been observed in regard to cluster motor ejection charges is that due to manufacturing variances, it is very rare for clusters to all fire ejection charges at the same...

I'm in the mid-Michigan area. In my suburban neighborhood as a kid, there was a large open grass field where I could launch a couple hundred yards away. A couple hundred yards the other way, a school yard was open with about 500 yards square. I could, and often did, load some rocket stuff into...

Sundays are one of my main days to do hobby stuff. I'd probably go buy stuff on Sundays if they were open -- maybe even get a chicken filet sandwich too -- but I guess Jeezus told them no. Thinking back to my college / young adult days working at gas stations and stores like Hobby Lobby, I...

Most T-shirt sources offer a variety of colors, although sometimes you have to tailor your design so it'll show up on certain colors. Many of us, shall we say, "waistline-challenged" tend to stay away from light bright colors because it does tend to emphasize weight.:oops: Oh ... and any...

I'm on about a half-dozen rocketry groups on FB but I'm in the middle of a 30-day sentence in FB jail for saying something nasty about a political person (on a politics site) so I can't post there or anywhere else on FB. Funny thing was, I'd said things as bad or worse about this political...

Yep, pretty much any cardstock-type paper will do. I got into the habit of using body tube scraps because they were pre-formed in curvature to match the interior of the tube.

I always hated the tube-slit method of shock cord anchoring so i used a version of the "shock lock" method G. Harry described in early editions of the Handbook. Instead of the bulky trifold method which could hang up the laundry going out (especially on BT-20 or smaller) you simply cut a piece...
