The Mythbusters liked my little duct tape rocket :)
Awesome! The Mythbusters liked my Nuttin' But Tape rocket and added it to their Duct Tape Projects photo album (FB membership req'd, sorry)! I knew I shoulda added a link to The Dungeon.
Follow the bouncing launch pad
Here's a video of a 2.6" 'throw-away' rocket made from unreinforced Blue Tube and flying on a 54mm Aerotech J1999 Warp 9 motor. As if the break-neck lift-off wasn't enough, wait for the slow motion replay and watch the pad. Yowzers! Six pounds of rocket and 491 lbs of thrust for half a second yields an estimated 80 G's of acceleration. Altitude and location were unknown even with a tracking transmitter. Rocket by Robert Synoski, video via Randy Ejma.
Balloon launch CATO
Space.com reports on the spectacular crash of a 400' NASA balloon carrying the Nuclear Compton Telescope (NCT). The NCT was a gamma-ray telescope built by the University of California, Berkeley. The 'launch' occurred at the Alice Springs Balloon Launching Centre in the northern territory of Australia.

Big a$$ (concept) rockets of the day
Scott Lowther has a hat trick of cool articles for sale:
- Boeing Advanced Multipurpose Large Launch Vehicle (AMLLV), "perhaps the most powerful {conventional?} booster ever envisioned… in it’s most powerful configuration, nearly four million pounds of payload could be carried by a vehicle with a launch thrust of 108 million pounds."
- Aerojet “Sea Dragon”, an extremely large rocket that would be built out of "conventional aluminum, built in a shipyard to shipyard standards."
- British “MUSTARD” concept for a “triamese” space shuttle from the 1960’s.
Big a$$ rocket of the day
Not big by HPR standards, but huge for it's class. George Katz points to an album with some great shots of the recent flights of his Acceleron V. Here is a composite image of the staging action. Source photos by Andrew Eltobaji. Click to see a big copy.

MiniSShot launch report
Sugar Shot to Space reports that they launched their MiniSShot test rocket earlier today. The rocket employed a 2-phase sugar motor with an initial burn, followed by a delay/coast period and then a 2nd burn phase. As seen in the attached video, phase one apparently worked nicely but there was an anomaly when the 2nd phase began. The flight computer/electronics package was recovered so hopefully they will be able to learn more about what went wrong. It was noted that the 2nd phase began at 12k'. Not bad for roughly half of a 'small' sub-scale motor.

Smartass forum responses
Often when I see a forum post title, some wisecrack pops to mind. I sure making such responses will just cause unnecessary turmoil so I generally keep them to myself.
Post: "Cheapest was to get a shoot out?"
Ignoring the first typo, which I read as 'way', I wanted to answer: "Cross Billy the Kid?"
(I bet you're glad you wasted 30 seconds of your life that you'll never get back.)

Falcon HTV-2 (partial) results
Spaceflight Now reports that the Minotaur-4 'Lite' deployed the HTV-2 at more than 20 times the speed of sound. However, contact was lost around 9 minutes after liftoff. After deployment, the HTV-2 was to perform a series of sweeping turns to bleed off excess energy and demonstrate its cross-range capabilities.There is no word on how much, if any of these maneuvers were completed before communications were lost.

Or, at least that is what Spaceflight Now is reporting.

T+plus 19 minutes, 58 seconds. SPACECRAFT SEPARATION! The Centaur upper stage has deployed the X-37B Orbital Test Vehicle following today's launch from Cape Canaveral.Besides the fact that I was otherwise occupied, I had no great interest in following this in real-time. All the best stuff should occur after the flight status reports stopped. As for a video of a mere Atlas launch, I'd rather watch/re-watch videos from Red Glare 8. Jaded, am I?

Air-Launch Sortie Vehicle, part 4
The Space Review eatures the 4th and final part of Dwayne Day's series on the AFRL's “Space Sortie System.” (See: “Fire in the sky,” part 1, part 2, and part 3, in previous issues of The Space Review.) This quote says it all:

Landshark 3.0 (quick update)
After the drowning of version 2.0, I have plans for the next-gen Landshark. I'll post photos of the major components later. But they will be:
- The fin can is intact and will be reused. I managed to beat out the stuck motor. Paper labels suck. Once I got it out, I inserted a RMS case to make sure the mount stated round while it dried. I reinforced the out-of-round decorative tubes with piece of Semroc dummy 18mm motors and dowels.
- Another 3" mailing tube ~40" long. With the fins on the motor mount, I'll have to slot the tube to the end.
- I'm changing the nose to give it a new look. I have a stubby 3" cone that I made with a found plastic doohickey. I guess you'd call it a truncated oval. I'm going to drill the tip out for a piece of 29mm tube and add a conical PML resin cone. This should give it a sorta ram-jet look. I may add a payload section to lengthen the rocket but will wait to see what it looks like with the short nose. This may also be needed for stability.

Launch Report 2010-4 (Red Glare 8)
Location: Higgs Farm, Price, MD (MDRA)
Weather: high 50's; partly cloudy; very windy and chilly
Total flights: Today - 2; YTD - 21
Total motors: Today - 2; YTD - 21
As usual, I planned to only attend one of the three launch days. As it turned out, fate picked Saturday for me. I'll first point out that a bad day on the field is better than a good day doing yard work! That being said, it was a pretty crappy day, starting with the big pile of manure in the parking area:
The winds were pretty bad and they got stronger as the day progressed. By 4 PM I was glad that I'd brought ear muffs. As you read my flight reports, you'll see I only had 2 unsuccessful flights :( The good news is saw a bunch of cool flights and some awesome rockets. Here are the three highlights:

- Burl Finkelstein's "Big V2" on a central N and 2 O's. This alone made the trip worth it. You can find a few photos here and a (poor) video here.
- Neil Brown's "Dinosaurs Rocket-et Extreme" - 20' tall and weighing in at 385 lbs - flew on an N4000 and 3 outboard K830, Spitfires. You can find a photo here and a video here.
- Steve Eves had his 1/9-scale Saturn 1B on display. It should fly later this year along with another 1/10-scale version. See the four photos here.
My Flights:
- Hat of Death on a Vulcan G motor of unknown designation - It chuffed its way off the rod and, once the motor came up to pressure, spun wildly. It has a few additional battle scars.
- Landshark 2.0 on a G75-7 Metalstorm - Nice boost although the sparks weren't as noticeable as on the promo videos. Maybe that was due to the wind? Ejection was a second or two late, but that was expected. Unfortunately, the Landshark decided to try to return to the sea. It was too water logged and didn't survive. I'll reuse the fins and maybe then entire motor mount if I can ever get the paper label-wrapped motor out.. Before and after photos photos here. And a bad video.

The quest for 300 psi
George Katz updates us on his experiments with fiberglass-reinforced PET bottles. It will be cool to see what his big and complex water rockets can do when pressurized to 300 psi. He recently reported a personal record of 810' on his clustered and staged Acceleron V at a mere 120 psi. He estimates that 30 of the extra psi is needed just to compensate for the weight of the reinforcement. As usual, he provides data and photos. And warnings about testing at those pressures - he tests inside an old scuba tank (see attached photo)!On another note, he has acquired a LOC/Precision Weasel 'pyro rocket'....

STS-1, April 12, 1981, do you remember where you were?
29 years, I can hardly believe it. I was in the MCC babysitting some new equipment. Although it was just shadowing the ops systems, we staffed it before, during, and a short time afterward. That was SOP for ops systems and I suppose if it had hiccuped it would have been useful to see how long it took to resolve the issue. It didn't hiccup and afterward the powers-that-be filed through to take a peek for themselves.
X-37B speculation
I'm fascinated by the possibilities raised by the X-37B. Space.com has another article reviewing what may be going on with the "Flying Twinkie." Reusable, hypersonic, launch on demand, insertion to almost any orbit, unpredictable until ground tracks can determine the orbit, flexible mission set, up to 270 days on-orbit. Sounds cool, hope it works better than expected.

More on the Douglas Orion
Scott Lowther provides more details on the Douglas Orion vehicle. A few quick points:
- It has a small, curved pusher plate.
- Fuel is a thick layer of ablative material on the plate vs. an external 'propellant' that is vaporized and impacts the plate.
- Bombs are not ejected through the plate but rather in radial mechanisms. Since these can not be in line of sight of the explosions, the bombs need active guidance.

Meteoroids kill satellites
![]() |
| The author with the Los Alamos Portable Pulser. (Photo: Chip Simons) |
The IEEE Spectrum has an interesting article on the danger that meteoroids pose to satellites and other spacecraft - Space Invaders: Shooting Stars Can Shoot Down Satellites. The author, Sigrid Close, is a Stanford professor, asteroid hunter, and TV show host. She reviews the dangers these objects pose to satellites and chronicles some known and suspected cases of meteoroid damage. Two interesting notes:
- Aside from their kinetic dangers, meteoroid impacts also generate electrostatic discharges (ESD's) and electromagnetic pulses (EMP's), which also can disable satellites.
- She mentions Bill Cooke, who is the lead for the NASA Meteoroid Environments Office at the Marshall Space Flight Center and an avid sport rocketeer!

Anyway, here are a couple of repair tips. Two old and one new.
Anyway, here are a couple of repair tips. Two old and one new.
- To replace a broken shock cord, you can install a Kevlar leader along the side of a launch lug as follows:
- Punch two small holes, one on either end of the lug in the fillet area.
- Feed the Kevlar twine into the back hole and fish the end out.
- Tie a double knot and pull the knot against the hole.
- Feed the loose end through the upper hole and fish it back out.
- Keeping the line taut, apply a fillet with 5-minute epoxy, and work a bit into the rear hole where the knot is.
- If not exclusively using the Kevlar as a shock tether, you can attach some of your favorite sproingy material.
- Add a couple of folds of tape (I prefer duct tape) at the point where the Kevlar line touches the body tube. This will reduce Kevlar-induced zippers.
- Now for the new one. I found several of my Nomex 'chute protectors were tearing in the middle. Holes will allow gas to pass so this is not good. I found duct tape works as a decent patch material. It adhered well and was still in place after the flight. I don't know low long it will last, but it's cheap and easy to replace if it falls off.

ROMBUS III nuclear rocket
Scott Lowther provides a preview of his Aerospace Projects Review V2N6, which will feature the Douglas ROMBUS/ICARUS/Ithacus/Pegasus. The linked post includes a low res, but detailed, view of the ROMBUS III nuclear Mars rocket. The Douglas Aircraft Co.'s proposed "Reusable Orbital Module-Booster & Utility Shuttle" (ROMBUS) concept was a heavy lift VTVL SSTO RLV follow-on to Apollo. The 'III' series would have had four gas-core nuclear rocket engines in its upper stage and a Mars-bound payload equipped with gas-core and solid-core nukes, and another nuclear reactor for power. More on ROMBUS can be found on Encyclopedia Astronautica, which is the source of the simplified diagram I've attached.

Here's old Wired article on a novel use for rocket fuel: clearing WMD bunkers (or any other enclosed area that you want to incinerate).

Cool label, so-so contents
This weekend, I tried some Ed Hardy light beer. I picked it because of the label and branding. Made in Mexico. Typical light beer. Not bad, but typical. Probably was overpriced but I didn't pay attention. Unless you want the label to decorate your rocket, I'd recommend buying any mainstream light beer (Coors, Miller, Amstel) instead.

Paul Breed, after having to cut up and scrap his landers, has decided to get certified on, gasp, a garden variety high power sport rocket kit. He needs the certs to he can buy motors for some undisclosed project. He has generally eschewed sport rocketry but, has plans to move on to 'regular rockets' from his previous hovering landers. I guess his plans are not that undisclosed, but I didn't think he'd need/want commercial motors. Personally, I think it makes sense to do some HPR before building a liquid-powered rocket. Anyway, I hope he has fun along the way!
And, how can not like a guy who HATES PAINTING?

Everyone needs a robot skeleton sidekick
Tonight, along with all the other hobos, cheeky monkeys, and members of his robot skeleton army, I be watching the debut of Graig Ferguson's robot skeleton sidekick, aka Geoff Peterson. Geoff was built by Mythbuster Grant Imahara and until now has been top secret (well, at least a little bit). I don't know if this was being planned before Craig even mentioned the idea of a robot skeleton sidekick on-air, but I tweeted about it when he first mentioned it (patting self on back). Windows 7 wasn't my idea, but Geof was (well, at least a little bit).
Plans, as leaked on Pop Mech.
Two space launches
Expedition 23 Soyuz, April 2nd. This video has a really cool perspective. (via the Bayourat)
And, this morning's pre-dawn launch of the Shuttle Discovery. (found on Spaceports)
Oh, yeah, there are now a record 4 women in space - on Discovery, former high school teacher Dorothy "Dottie" Metcalf-Lindenburger and robotic arm expert Stephanie Wilson and Japanese Astronaut Naoko Yamazaki and, via the Soyuz, chemist/astronaut Tracy Caldwell Dyson.

Before Ky Michaelson there was Harry Bull
Sport rocketeers everywhere know that Ky not only builds cool kits, manufactures great recovery components, and hosts a big superbowl party but also has strapped rocket motors to most every kind of land vehicle. But I don't think he was doing so in 1931:

Rocket Driven Ice Sled Speeds Over Lake at 75 M. P. H.
PROPELLED by the fiery explosions of eighteen rockets, a new torpedo shaped ice boat, designed and built by Harry W. Bull, 21-year-old Syracuse University student, proved itself in a recent test an extremely speedy vehicle, capable of acceleration at a rate of 110 feet per second, or about 75 miles per hour—four times faster than that of the average auto.

Launch Report 2010-3
Location: Great Meadow, The Plains, VA (NOVAAR)
Weather: mid 70's; clear to high thin clouds; wind 5 - 10 mph
Total flights: Today - 7; YTD - 19
Total motors: Today - 7; YTD - 19
I was fortunate for both nice weather and the TARC competition. The latter resulted in two back-to-back launch weekends!
While at Ken Allen's tent, several people returned AT E15's and E30's. Evidently some batches are CATO'ing in large numbers. Then I got to witness a couple myself :eek: I don't know the subject lot(s) but think I'll try mine anyway. I also bought a 2-pack of the new E20's.
Ken should be getting his order of the new Metalstorm motors very soon. I want to fly a couple at Red Glare.

My Flights:
- North Coast Archer on an H165-6 - Excellent flight. The flame seemed redder than normal, and the Redlines are normally very red.
- North Coast Big Brute on a G38-4 - I couldn't fit my 30ga igniters or even a larger Copperhead so I went with a Copperhead for a 24mm motor. This motor was an old one given to my by Paul M. so I started worrying about a CATO. My worries were unwarranted as the flight was perfect.
- Lime Stiletto on an E9-6 - The RSO rejected the Stiletto for sitting too high on the rod (interference with the large bulbous plastic NC). It had flown this way several times but I CA'ed the First Fire tube from my Archer's flight onto the rear fins. Ejection was a couple of seconds late but the flight was good.
- Semroc V2 on a B6-4 - Nice boost but the Kevlar leader burned through. Both parts recovered.
- First Flight Corn Roc on a C6-3 - Nice flight. People liked this rocket.
- First Flight Semi Sonic on C6-5 - High flight that landed near the far edge of the field near the entrance. I picked it up as I left.
- Semroc LAUNCH Missile on a C6-5 - High flight, not too bad a walk due to a tangled 'chute.

Silicon meets AP
A reader just directed me to The Rocket Project. This is a student designed project sponsored by Sony and Intel and supported by Tom Atchinson of the Rocket Mavericks. Launch is scheduled in 9-10 days as of post time. The web site is a little heavy on the computer hype, but what the hey, the sponsors deserve their due.

La Mega Bomba - Sledgehammer Fireworks
Check out this crazy YouTube video of people in San Juan de la Vega, Mexico strapping explosive fireworks to sledge hammers and whacking them on an I-beam. Embedding is disabled. You may want to skip towards the end. Found via the (un)Make:blog. More about this on the Living in San Miguel blog here and here.
I have to admit I like things that go boom and as a kid blew up plenty of stuff with firecrackers of various sizes. However, I don't think I've ever drank enough to try that.

The latent April Fool's Day post
It seems all my cute ideas for April Fools posts only arise when it's not April Fools Day. That applies to all pranks not just blog posts. So, I didn't try to pull any.
I had considered the standard "I'm quitting rocketry" post. Or the "I'm quitting blogging" post. Or even, "It's April Fools and I'm not quitting blogging"...and then actually quit. Now you see why I didn't post anything.
Oh, the good but unrelated news. I messed up entering stuff into the calendar and it looks like I will be able to attend Red Glare! And that's no joke!
