Is that a rocket in your garage?


Here is an in-progress shot of the Beagle IV, 4 x Q-motor, atmospheric sampling rocket. Click through, look at the tags, the select 'all sizes' and look at the big version.

As for it's mission, Steve has some food for thought, including:

    Is the game of life in our future?

    The IEEE Spectrum tech talk blog calls game designer Jesse Schell's view of the future The Most Disturbing Presentation of the Year.  Jesse imagines a world where we earn points, ala frequent flier miles, for everything.  Game designers will take over corporate marketing.  Sensors will be ubiquitous and will track us as we navigate a maze of points and rewards.  Life itself will become one big game. 

    Images of The Matrix come to mind.  Big brother will both watch and manipulate.  Everything we do will be logged for posterity.  How would you act if you knew your children and grand children knew everything you read?  Everything you bought?  Jesse ends on an up-note that this might make us think about our actions and make us better people.

    It's fairly long but I found it interesting. More interesting than scary.  I'm more worried about the many pressing problems we are currently facing as a country and a society.  I guess this rates somewhere between health care and the zombie apocalypse.

    Global Hawk, NASA's New Remote-Controlled Plane


    NASA Dryden and GSFC have teamed on the Global Hawk Pacific campaign:
    For the Global Hawk Pacific campaign, the robotic aircraft will carry ten science instruments that will sample the chemical composition of air in the troposphere (the atmospheric layer closest to Earth) and the stratosphere (the layer above the troposphere). The mission will also observe clouds and aerosol particles in the troposphere. The primary purpose of the mission is to collect observations that can be used to check the accuracy of simultaneous observations collected by NASA’s Aura satellite.

    Hot times in DC

    The Capital Weather Gang notes that March came and went (almost) without the temperature dipping below 33 degrees.  This record, with readings taken at Reagan National, applies only to Washington DC.  Up here, we did dip below freezing a couple of times.  But still...

    So, when was the last time this happened?  The answer is never in the almost 140 years of record keeping!

    So, if snow records brought out the snow girls, I just couldn't resist corrupting my blog even further...

    Acceleron V video report (810' on H2O)

    George Katz, as promised, has updated his web site with a full report of his record setting (personal) water rocket flight. The update includes photos, altimeter plots, and flight event time lines. And, of course, a cool video with several ground angles, 2 sets of on-board video, slow-motion...the works! Check out the complexity of that wrocket!

    Spaceflight training on F-104 Starfighters

    The Southwest Research Institute reports:
    As part of the next phase in advancing suborbital research opportunities and their own flight preparations, Southwest Research Institute researchers and suborbital payload specialists Dr. Alan Stern and Dr. Dan Durda have begun a new element of spaceflight training with a series of jet fighter flights in F-104 aircraft operated by Starfighters Inc. at the Kennedy Space Center, Fla. The first SwRI Starfighters flights and the associated ground training, took place March 15-16.

    (The story via Clark Lindsey.  The photo is of my Starfighter.  No astronauts were trained during that flight.)

    JATOs in El Paso?

    On April 11, 1960, a U.S. Navy flying boat headed from San Diego to Baltimore via Pensacola made an emergency landing in El Paso's Ascarate Lake.  The 3000' lake wasn't big enough for the repaired plane to take off, so they needed the help of a good wind and four JATO units.  One of the three boosters failed the ignite, but three were enough.  Now that's something you didn't expect to see in El Paso!  I could have, but didn't :(

    NAR/TRA joint statement on legal fee recovery

    Full text of the statement:
    On Friday March 26, Judge Reggie Walton of the U.S. District Court for the District of Columbia ruled on the TRA/NAR motion for recovery of the legal fees we incurred in our successful nine-year case against BATFE regulation of APCP. The judge rejected the government’s argument that we were not entitled to any reimbursement for our attorneys fees.

    However, he ruled that we will only be reimbursed based on the artificially low hourly legal rates established for use in federal court cases, and only for legal work performed after the Court of Appeals remanded the case back to Judge Walton in 2006, including legal work on the fee recovery motion itself.

    The amount will likely be less than half of the $196K that we had requested (the amount we requested if the court would not grant recovery at an enhanced fee rate), but will still be substantial. The exact amount corresponding to the judge's decision has not yet been calculated. This re-calculation will need to be re-submitted to the judge by April 16, and for payment at some date yet to be established after an April 30 BATFE response to our submission.

    Launch Report 2010-2

    Location: Great Meadow, The Plains, VA (NOVAAR)
    Weather:  high 40's; clear changing to high thin clouds; wind 0 - 5 mph
    Total flights: Today - 8; YTD - 12
    Total motors: Today - 8; YTD - 12

    I got my flights up in record time despite there being tons of TARC teams flying.  NOVAAR has the best set-up: around 18 pads arranged in a wide arc, which allows people to load in one spot and fly in another.  Here are my flights:
    1. Prototype Monocopter on an F10 - Great long flight!  It went up a ways, leveled off for a while, and then headed back up. Very neat. Video missed due to operator error.
    2. Prototype Monocopter on a G38FJ - Great flight but not as cool as the F10.  Video embedded below.
    3. AquaBottleBat on an F35-4 - Great flight with ejection at apogee.
    4. Hostile Projectiles Delta X-15 on an D12-5 - Straight boost with ejection at apogee. Perfect landing too.
    5. BMS Astron Invader on an A8-3 - It pulled a tight arc and lawn darted.  Dead.
    6. HotRod Discovery on a C6-5 - Very high flight.  Never seen again.
    7. Semroc Tau Zero on a C6-5 - Another very high flight.  I finally found it.
    8. Quest MLAS on an (Estes) C6-3 - Great boost.  Unfortunately, all three chutes were BBQ'ed and it came down in streamer mode.  Nevertheless, all 8 fins remained attached :)

    A big congrats to George Katz!

    George reports from Air Command that he set two personal water rocketry records.  He set a new altitude record of 810' (246m) using his Acceleron V booster rocket with the Axion IVb sustainer. Wow!  This beat his previous record of 639' (193m) by a good bit.  He also set a duration record of one minute.  Way to go George! For now, you'll have to pop over to his blog to see the record setting rocket boosting.  When he updates his main page I'm sure he'll have a nice YouTube video that I'll be able to embed here (hint, hint).

    Gotta run...to NOVAAR (rumors of me not flying any more have been greatly exaggerated).

    NAR/TRA to recover some of their fees for APCP litigation

    About a year ago, Judge Walton ruled in favor of the NAR/TRA in their lawsuit against the BATFE, thus vacating the classification of Ammonium Perchlorate Composite Propellant (APCP) as an explosive.  Today, he granted a partial repayment under the plaintiffs' motion to recover their legal fees.  Under today's order, NAR/TRA can recover the fees they incurred after the case was remanded to the Circuit Court of Appeals bcause the defendants didn't follow instructions by failing to "adequately explain why it came to the decision it did in light of contrary evidence in the administrative record."

    This is probably a poor summary but, luckily, Rocketry Planet has a more lengthy article.

    Put one of these in your garage for a few hundred bucks


    Well, maybe not in the garage but on the door. A friend sent me this:
    A German firm called "Style Your Garage" - creates posters for garage doors that make it look as if it's actually showing the interior of your garage, and what's in it!

    Prices range from $199 to $399 for the double-door! All but guaranteed to make passersby take a second look!

    So, you want to sea-launch your V-2?





    Well, apparently, so did the Germans.  Scott Lowther has an interesting blog post on the “Prüfstand XII” (”Test Stand 12”) concept.  His post includes some background/history and the attached image.  In short, the idea was to tow the launcher to station in a horizontal position, raise it to the vertical position, open the top, and launch.  It's not clear that this would have worked, at least reliably. This may be the subject for a future issue of his Aerospace Projects Review e-mag. So, if interested, you might keep and eye out for it.

    Blogger's rights?

    The DCist blog, prompted by a minor brouhaha between a local blogger and a local business, points out that Bloggers are not liable for comments added by third parties and have no responsibility to remove them.  The Blogger in question removed a comment after receiving the threat of a lawsuit. I have to admit I'd likely do so also.  Unfortunately, everyone also has the right to be sued without legal merit.

    Flight of the (SS2S) Phoenix

    Another good Space Review article: A spacefaring hydraulic civilization by Taylor Dinerman.  I don't know how important water will be on the moon, but those planning NASA's future should be considering the subject.

    Sunday rocket reports (added a Blue Ball aftermath photo)

    Clark Lindsey found this video of Mastens' Xombie fliying at FAR.  That is an awesome perspective. The flight went to just over 1000' at a speed of 60mph both up and down.



    Unreasonable Rocket reports bad news via Twitter:
    Bummer day crashed rocket and favorite food place in cal city(xspot) closed til further notice.

    Rocket gone awry. One of our party was downwind and received a spritz of H2O2

    This weekend's weather has been great and the reports from MDRA indicate everyone is having a great time.  I was busy yesterday but also enjoyed the weather.  Today, I just couldn't get motivated.  I thought about the drive, the meager rockets I have on tap, and just slept in.   I think I may be slipping into my 3rd lapse in the hobby.  If I do, I think I may be too old to become a BAR for the 3rd time.

    NASA: photo blog, social media, iPhone, archiving

    I just found the NASA Images blog (hat tip to Phil Plait).  Many of its posts point back to the NASA Images site, which I had found a while back.  It also talks about stuff like their free iPhone App and their efforts to archive their social media

    I don't know the details about their requirements to archive such stuff but, for NASA, data archiving is more than just a good idea, it is the law.  They already made a big deal about archiving all emails but, again, I don't know if this fell into the same category as mission data.  NASA is working with with Archive-It (part of The Internet Archive) to provide the NASA Images Social Networking collection.  It looks like it is

    I point this out as a curiosity since I can't see much use for this personally.  You could spend you whole life tracking the real-time Twitter and FaceBook feeds much less trying to find specific stuff in the archive.  I did poke in a few spots and see that, if you interact with NASA folks, your words and images might also sneak into their archive too. Wow.

    FAR, FAR away

    A while back, Paul Breed tweeted (can't believe I used that term) about this week end's activities at FAR, which will include a flight of his Blue Ball, Masten's Xombie, a solid propellant project, a sugar shot to space (SS2S) test, and some HPR.  The Launch Pad reports that Unreasonable Rocket and Masten will shoot for flights to 1200 ft, the highest they can fly without an FAA permit.

    Sleuthing Blue Origin - Clark Lindsey notes that Blue Origin will be getting gaseous hydrogen (GH2) via a DoD procurement.

    The Next Big Future posts that General Atomics, while not building a nuclear pulse rocket anymore (or are they?), is under contract to develop an Advanced Containment Launcher (i.e. an E-M rail gun).  This work is being done for the Office of Naval Research’s (ONR) and should be ready for a demo in 2011.  This is not rocket/space related but I like rail guns.  Or at least stories about them.

    Unintended consequences

    I wonder if cost of not doing Constellation will be higher than doing it?

    I haven't given this a lot of thought so don't criticize me too much. Consider this a rhetorical statement. But, maybe it's not a joke.

    DoD folks are concerned that NASA's cancellation of Constellation, specifically the Ares SRM's, will raise the cost and reduce the reliability of their EELV programs.

    I'm sure you can't believe anyone's numbers and I have no idea what the increased cost might be, but this should be considered somewhere somehow. Quantifying any possible reduction in reliability is pretty tough (I personally am skeptical about any statistical predictions, which is another story). But, while the loss of tens of thousands of skilled aerospace jobs will make for a good hirer's market over the short term, it will have down stream impacts.

    Thoughts?

    In Van Horn, Texas, their wide-open (new) space is still pretty quiet

    An article in the El Paso Times  notes that, despite some early excitement and anticipation, the proximity of Blue Origin's facility has not created much of an economic boom in the quiet West Texas town of Van Horn.  Most workers at their facility, which is located about 25 miles north, have come from other areas of the country.   Interestingly, this is what was projected by Blue Origin's Environmental Impact Report, which was published in 2006. Although many locals remain skeptical, some hope that recent NASA funding might spur the new-space company's success, a little of which might bleed over into Van Horn.

    Odd Blogger problem, and a fix

    Earlier today, I tried to access the mail form that I link to here on my blog. This was originally in an HTML widget on the sidebar but I recently moved it to a dedicated page.  I found that clicking the link led to a blank page.  I investigated and found my mail form was in fact still there.  And the URL displayed in the menu bar was correct!  I was really confused.  I was working in Firefox 3.6 and later found that the link worked in Chrome.  I was still confused.  Next, I discovered that, if you placed the cursor on the end of the URL (on the blank page) and hit enter, the mail form popped up. Huh?

    I still don't know what odd interaction is going on between Blogger and Firefox, but I know how to work around the problem.  It is known that Blogger's parsing of text-to-HTML has caused occasional problems.  For instance, it occasionally drops the closing tag form an embedded object.  Anyway, I noticed that Blogger was converting the tilde (~) in the link's URL with %7E, its ASCII equivalent. I then decided to manually edit the link and try the HTML code for that character. Here it is without the leading ampersand so it won't be converted: #126;  Voila, it worked!

    There is one more 'gotcha'. You have to publish the post from the 'Edit HTML' screen where you make the edit. If you later try to edit the post again, Blogger reverts to the Compose screen and, you guessed it, converts the tilde back to the hex value. Grrrr.


    So, this link leads to a blank page while this one brings up my mail form. If you hover over them, they appear the same because your computer converts both forms of raw code to the same ASCII character.  Strange.

    Decertified motors may be flown at Tripoli Research Launches

    Rocketry Planet reports that TRA VP Terry McCreary has notified the prefectures that commercial motors that have been decertified can now be flown at TRA research launches. It's unclear to me whether this is a physical change to the research code (PDF), a clarification, or a reinterpretation.  I'll leave the parsing to others.

    In case you Blogger users were curious about my last few posts...

    If you use Blogger in Draft (via the check box on your dashboard), you too can redesign, enhance, beautify, and possible muck-up your blog with Blogger Template Designer.

    One more try...(updated)

    This time, something simple with very few bells and whistles...but with a background image...

    So far, I'm happier.  Despite even more complicated template code, I got the blogscrolling code in.  Whew.

    Doesn't look like the blogger widget that displays the recent comments in the sidebar is working.  Not the most important thing to me.

    Stupid new template, grrrr

    I only had a few comments on the new template(s), but the last one made me decide to fall back to my original (at least original as of mid-afternoon).  I decided that the convenience I found with the three column format wasn't worth aggravating my few loyal readers :) There were so many options and I think things were getting worse instead of better.

    I thought about readjusting the new template for 2 columns.  But again I fell prey to too many options -  Background colors, fonts, background images, etc, etc, etc.  I liked the idea of background images but I was getting nowhere finding the right combination of everything.  My new format may not be artistic, but at least it's familiar.  I wish I could load it into the new format editor as the starting point.  But, nope.

    More on the blog template

    Lost my 'blogscoll' code that added the slider bar to my links list. Probably just as well not to diddle with the code.

    The double sidebar format has caused me grief, but I kinda like my labels appearing before my eyes. I use them a fair amount but others probably don't. I don't like that YouTube doesn't fit. I can probably embed a smaller version.

    I like the white on black. So far others don't.

    Looks better in Chrome than Blogger.

    New template...formatting tweaks needed

    I'm going to shuffle some stuff around and adjust sole of the text colors, etc.  Images in the body will have to be smaller.  I'm going to tweak the posts that reside on the current main page.  Older stuff may not fit and I can't go back to the beginning and fix everything.  Comments?

    The Clotho Project

    How far off the earth's surface does life exist, and what is the nature of the organisms that live there?

    The Clotho Project, a suborbital biological sampling research project that is being planned by the Rocket  Mavericks in collaboration with several scientific, academic and research institutions, will attempt to answer that question. The vehicle itself is the 2-stage, 4 x 'Q' motor Beagle IV. Its booster will have three 6" Loki 'Q' motors and the sustainer will have one 'Q'.  Sounds like the Beagle 2 that I mentioned in January.  I don't know if I got the number designation wrong back then or if it changed.  No matter.  It's just cool that sport rocketeers are going to be supporting some real science. (hat tip to Steve Jurvetson)

    Beagle IV Biosampling Rocket

    Painted the Astron Invader

    Following the instructions, I laid on a very thin layer of paint to at least most of the exposed surfaces.  The recommendation was to paint the bottom black for visibility under glide and the top fluorescent to help spot it after landing.  I did half and half on top and bottom.  With an 'A' or smaller motor, visibility in the sky will not be a problem and, even though I used green, it won't be hard to spot on either a plowed field or mowed grass.  If it finds a bean patch, so be it.

    Swiss Army Knife for geeks and airline passengers


    This Victorinox pocket knife includes a laser, a fingerprint recognizing memory stick and a Bluetooth remote control for your presentation slide-flipping laptop....as well as a blade, nail file, screwdriver, scissors, and key ring.  I think I want one.  Even though I don't flip slides anymore.

    To help with that pesky airport security, they also make a non-bladed one.  Which isn't technically a knife anymore, eh? (as seen on Toolmonger)

    Test glide ambiguity

    Snow cover melted..check. Warm...check. Calm to no wind...check. Time to test glide the Astron Invader. I forgot whether I had balanced the glider WAY back before Snowpocalyse but thought I'd give it a toss anyway.

    Historically, gliders do the best job of showing how I can't get all my parts glued on perfectly. And this one is no different. I really got mixed results. Once it went a good way and then seemed to stall a bit. Once it nose dived quickly. A couple of times it seemed to glide after flipping over. I tossed it parallel to the ground, right side up and inverted and even chunked it in the air as high as I could. Finally, I went onto the deck and threw it out at about a 45 degree upward angle over the drop off into our lower yard. I stayed upright, pulled a wide 180, and dinged it's wing on the chicken wire that keeps our dog our dog. 

    Based on this last 'success', I decided this was close enough so I glued the motor tube extension in place and will fly it as is.  Best case it glides half way decently.  Worst case is it will be unstable.  I think I made sure it's CG was appropriate for the latter. Maybe I'll double check.

    Mamie or the rocket?

    The costs of manned space

     

    Author Claude Lafleur took NASA's reported expenditures, converted them to 2010 dollars, and made a colorful graph.  Such graphs beg for discussion, which you can see on The Space Review.  I didn't try to digest his more detailed page that breaks down how he got his figures.  Budget analysis is a bit like statistics - "There are three kinds of lies: lies, damned lies, and statistics." (Mark Twain).  Nevertheless, his analysis is quite interesting. A couple of the more interesting tidbits:
    • The cost per Apollo mission, in 2010 dollars is 18B!
    • Even though its total cost is about twice that of Apollo, the cost per Shuttle mission is a paltry $1.4B. (He includes the Shuttle's ISS mission in the cost analysis of the latter, but still...)
    • The cost per crewman-day on Skylab was 5.5M.
    • The cost of a crewman-day on ISS is 7.5M (including the required Shuttle flights and contributions from all partners.)
    • Looking at current budget plans, Exploration programs, despite the cancellation of Constellation, will be funded at $4B/yr through 2015.  That's more than ISS.

    Space concept art from Soviet Russia

    Teknika Molodezhi - USSR, 1955.



    io9 has a cool gallery of retro space concept art from 1950's Russia.

    Is NASA funding poised to shift geographically?

    Senator Barbara Mikulski (D-MD) has been a strong supporter of NASA, both in general and specifically for work performed at the Goddard Space Flight Center (GSFC). As the Chairwoman of the Appropriations Subcommittee on Commerce, Justice, Science (CJS), she once again is wielding her influence to shape NASA's course.

    Clark Lindsey provides a couple of links regarding the potential shift of funds from the Constellation program to science and COTS programs.  GSFC is a science center and Maryland has a stake in COTS.  Maryland is involved in the Mid-Atlantic Regional Spaceport, which is collocated with the Wallops Flight Facility.  And it happens that Wallops not only nearby but is also managed by GSFC.  Finally, one of the big players in COTS, Orbital Sciences Corporation, has offices here in MD.

    It's interesting that the Huntsville area, which stands to be a big loser in the post-Constellation NASA, is the fourth largest area that contributes to her campaigns. Further, Sen. Richard Shelby (R-AL) was instrumental in her recent fundraiser.

    Got design motivation?

    BARCLONE has, as of 3/5/2010, 722 unique rocket designs.

    But, don't forget, EMRR has 3,785 articles covering 1,705 commercial products and 2,080 MOPS (modifications, out-of-production, plans, and scratch) rockets. There are also 2,281 RockSim models.

    For countless scans of commercial products, both in- and out-of production, check out JimZ and Ye Olde Rocket Plans.

    And, if this doesn't help, I just don't know what to tell ya'.

    Bacon is both bad and good

    First I find this video...



    I'm not sure it was that the bacon that was unsuitable for a rocket as much as the builder was unsuitable as a rocketeer. But I didn't have my sound on so maybe I missed something :rolleyes:

    Then, I thought that I'd create a graphic to rate the various uses of bacon on a scale of '1' - '10'. For instance, bacon and eggs and a BLT would be a '10' and bacon vodka and muffins would be a '3' - '4'. And I guess for now a bacon rocket would be a '1'. Well, I wanted an image of a slice of bacon to make the graphic. But, I got sidetracked with another '10'...


    So, no goofy graphic to rate bacon.

    New highly classified project started (clarification)

    It will fly on 29mm motors and will spin wildly.  That's all I can say. The weather is looking up and I hope I can make the next MDRA launch!

    PS - It is not a scratch build so if I told ya', I'd have to kill ya' fast (i.e. before the designer found out) :)

    Tau Zero completed




    Well, I took advantage of a couple of dry, warm(ish) days and completed the Semroc Tau Zero.  This is a nice looking, futuristic rocket kit that flies on 18mm motors and recovers via a streamer.  I especially like the cone, which resembles a sleeker version of the Honest John cone. Anyone familiar with this kit will notice mine looks funny.  Different, not haha.  I think.  First, I flipped the fins so they are swept backwards.  This is not optimal for streamer recovery, but what the hey?  I also deviated from the recommended paint scheme.  I used Dupli-Color METALCAST, with the base coat serving as the color coat for most of the rocket.

    On the exponential progression of information technology

    This fascinating video was reportedly played at Sony's annual shareholder meeting. The content is attributed to Karl Fisch, Scott McLeod, and Jeff Brenman. Watch it.

    A ram-rocket in the news

    Via Parabolic Arc, I see the Indian Space Research Organization (ISRO) successfully conducted a flight test of its scramjet enhanced sounding rocket today.  In today's test, the scramjet combustor was passive.  The goal of the test appears to have been merely to reach and hold an optimal velocity.  They report held the desired Mach number (~6) and dynamic pressure for some 7 seconds.  In the next test flight, the scramjet should be enabled.

    From Wizards Roost to the Space Shuttle, and beyond

    Back when the X-Prize Cup was held in Las Cruces, I made several posts about other space and semi-space-related attractions in that general neck of the woods. Here's one of the posts. Well, a few of those are in Texas and not so close.  And, I left out places near Albuquerque and Los Alamos. Oh well.

    Now I see the New Mexico Museum of Space History (which itself is on my list) has been compiling a list of their own...and its a big one.
    For more than two decades, The New Mexico Museum of Space History, a division of the New Mexico Department of Cultural Affairs, has been developing the “New Mexico Space Trail”. Beginning as a listing of sites within the state that have contributed to man’s exploration of space, from archeoastronomy sites to NASA facilities, it soon became apparent that New Mexico has always had space! Forty seven sites have been identified to date, and include sand paintings of the Navajo, the petroglyphs of the Zuni, the rock alignments at Wizard’s Roost in the Sacramento Mountains (similar to the much larger site of Stonehenge), astronaut training sites like Zuni Salt Lake, the Jemez Mountains and the Rio Grande Gorge area. Where else but New Mexico can the footprints of Spaniards who trekked the El Camino Real cross the path of future astronauts at Spaceport America?
    The museum is producing a series of 52 three-minute radio programs, live radio call in programs and supporting promotional material to present the state's rich space history. This first program is available in its entirety at http://www.alamoam.com, click on the link for Tuesday, March 2, 2010. The second live radio program is scheduled for August 10, 2010, also on KRSY 1230 AM.

    The attached photo, by Peter Eidenbach, is of the Wizard’s Roost prehistoric observatory.  Located in the Sacramento Mountains, it was used to predict the yearly summer and winter solstices and the heliacal rise of the star Sirius. Built between 100 B.C. and A.D. 900, it is one of the oldest sites on the “New Mexico Space Trail”.

    "Is that a real Corn-Roc, or is that a Sears Corn-Roc?"

    First, I'll apologize to Frank Zappa, where ever he is, for replacing 'poncho' with 'Corn-Roc' in the title. I just found that I had never posted a photo of my First Flight Hobbies Corn-Roc.  Mine was a beta test version and I was sworn to secrecy until it was formally released. Here it is:





















    So, I ask again, "Is that a real Corn-Roc, or is that a Sears Corn-Roc?" Click-through below to find out.

    Dual deploy water rocket

    George Katz shakes his fist at the rocket eating trees.  That is, now that he has a dual deploy ejection mechanism to keep his rockets, and their on-board camera, out of said trees.  Read all about it in his Day 88 launch report. Or, if you want to stay here, the following video shows the mechanism in action both in a static test and in flight.  Cool on board footage.  And a CATO.

    The Tycho Brahe capsule

    I was focusing on the rocket part of Copenhagen Suborbitals' work. But the manned capsule is worth a look too.

    Video model rocket how-to's (reminder for newbies)

    Just though I'd post a reminder that Tim VanMilligan of Apogee Components now has 32 videos available. Today's Topic: How to Select Rocket Motors for Your Own Rockets - Part 2 of 2

    Ooop, left something off my previous post

    It was a snow post, after all...

    Our three big snowstorms all (maybe) ranked in Top 10

    Frank Roylance has ranked the three big snow storms we saw this winter based on data from BWI airport.  He also discusses how some of the other storms that were previously ranked by the NWS may have actually been multiple storms, since "no snowfall that lasts four days can be considered the consequence of a single storm."

    I mostly point this out to myself for future reference.  Although we are considered in the DC metro area vs. the Baltimore area, we are actually fairly close to the same distance from each. Without looking at any data, our snowfall is generally higher than what's reported at Reagan National.  But, from the last storm, ours was also clearly a lot less that what BWI saw.  Hence the 'maybe' in the title.

    From Frank's post: 

    1. Feb. 15-18, 2003:  28.2 inches
    2. Jan. 27-29, 1922:  26.5 inches
    3. Feb. 5-6, 2010:  24.8 inches
    4. Feb. 11, 1983:  22.8 inches
    5. Jan. 7-8, 1996:  22.5 inches
    6. Mar. 29-30, 1942:  22.0 inches
    7. Feb. 11-14, 1899:  21.4 inches
    8. Dec. 18-19, 2009:  21.1 inches
    9. Feb. 18-19, 1979:  20.0 inches
    10. Feb. 9-10, 2010:  19.5 inches

    Here's the latest ranking that I've seen from National. I don't think the Feb. 9-10 storm ranked down there.

    The race to be the biggest (amateur rocketry)



    Gizmodo is featuring the work of Copenhagen Suborbitals (C-S) and their HEAT-1X project. (Yesterday, I posted an embedded video of one of their hybrid motor tests. Cool stuff!) The blogger points out that the HEAT series are all-metal rockets as opposed to Steve Eves' 1:10 scale Saturn V, which is largely cardboard, wood and of course fiberglass.  Not to discount these fellows' efforts, but metal schemtal.  At 36 feet + (~11 meters) the Saturn V is still taller than the HEAT-1X. The image at the top is from Gizmodo.  If I has a better graphics program on this netbook I might have modified it to show Steve's rocket.

    Back to not discounting the Danes' work, it is clear that their goals are more lofty, both figuratively and literally. Steve's Saturn was built for fun and bragging rights while C-S is on a mission to "develop a series of suborbital space vehicles - designed to pave the way for manned space flight on a micro size spacecraft."  I can't say anything bad about that.  Except the Saturn V is still bigger :raspberries:

    (I'm categorizing their work as 'professional rocketry' since, despite being amateurs and non-profit, their work seems closer to UPAerospace than it does to Steve's operation. Plus, if they can reliably and repeatedly make it suborbital, they likely won't be either for long.)
