Last December, a good friend, coworker, and pioneering space maverick Aleta Jackson passed away. Aleta was kind of like the mother of XCOR, and she treated us all like a loving, nurturing mother. She was a very capable and motivated individual, too. A lot of my coworkers and even classmates at Iowa State looked up to her as a role-model. She was particularly an inspiration to girls everywhere who aspire to greatness in the field of astronautics, space, and aerospace. Aleta's whole life was dedicated to opening up the realm of outer space to the rest of us. She was a very capable person: she learned welding, she spoke Japanese, was a huge science fiction nerd (and she could write, too), she loved to build things and work with her hands, and she was good at making connections, always seeming to be at the foundation of every enterprise she undertook, behind the scenes making it all work. She was very subtle in some ways, and very ferocious in others! (Who could forget the story of her holding three burglars at sword-point with her katana until the cops arrived?) Aleta was the first person to contact me from XCOR asking me if I was "still interested" in the internship position. Her description of what life and work on the Mojave Air and Space Port made me almost explode with wonderment and excitement. Of course I am "still interested"!!! She tried to downplay it and make it sound like a bad idea to come out, but for some reason it had the opposite effect, and just today I learned that all of the interns and new hires got a similar warning from her about the hardships of working on a dusty little spaceport for a little rocket company. Aleta always took care of us at the office and helped to create a wonderful, creative and easygoing work environment at XCOR. She always told us to go home and recharge if we were working too hard. Aleta and her husband Dan were very gracious and let me stay at their house in Mojave for free while they were trying to sell it. Unfortunately I didn't get to see Aleta since then, and I really regret that. I wish I'd taken the time to get to know her better. Sometimes you don't recognize how much someone means to you until they're gone, and I mourn that. This afternoon was her memorial here in Midland. Everyone had very fond memories of her and I enjoyed hearing stories about her from people who knew her much better than I did. </div>

In an effort to revamp my web presence, I made a commitment to return to blogging, which in all honesty is more for my own benefit than for any readers that I still may have out there, because I feel it keeps me on track and focused on learning, exploring, and is a nice record of life experiences. It's like a more public version of my journal, (which I have been keeping regularly since 2005). </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Anyone have any good New Years Resolutions? Well, I really hate the term. So I've been sticking to an ollllllld term I picked up from my National Novel Writing Month days, called "Big, Fun, Scary Adventures", or BFS Adventures, which are like resolutions, but they must be big, fun and a little scary; something that takes you outside your comfort zone and grows you as a person. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
I'd like to share a few of mine!</div>
<ul>
<li style="text-align: justify;">Get back into archery</li>
<li style="text-align: justify;">Complete 30 paintings (up from last year's 20)</li>
<li style="text-align: justify;">Read 30 books (same goal as last year but only read 17... FAIL)</li>
<li style="text-align: justify;">Start blogging and YouTubing again. Goal: 50 blog posts and 20 YouTube videos. (My channel is <a href="http://www.youtube.com/user/DTHRocket">www.youtube.com/user/DTHRocket</a>)</li>
<li style="text-align: justify;">Transcribe 50 children's stories from YouTube in Chinese and learn the vocabulary. This is a new method I've been using to further my Chinese proficiency. My girlfriend Lulu has been helping me a lot!</li>
</ul>
<div style="text-align: justify;">
I have a few others, but one of them I'm a little hesitant to share online!!! Suffice to say big life changes are on the horizon!</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Speaking of life, what am I up to these days? I'm currently living in Midland, Texas, and still work at XCOR Aerospace, now as a full-time engineer! Life is pretty good. Lulu is attending grad school in Austin, and I try to drive down to see her a couple times a month. It's pretty hard being so far away, but it sure beats an America-China long distance relationship!</div>
<div style="text-align: justify;">
<br />
I'd like to touch on one thing I've been struggling with in the past few years. If you've been following this blog since it began in 2008 you probably have a clear sense of how ambitious I've been about reaching space and going far in my field. But to be honest, starting midway through college I've felt a pull in a much different direction. Don't get me wrong, aerospace is a deep passion of mine. But it isn't my everything. After my experience in China and making so many Chinese friends, I really felt God calling me there to serve Him. I don't know what that looks like, but I'm still praying about it. Is there tension between my love for aerospace and my love for China? Sometimes I feel there is, but not necessarily.<br />
<br />
The bottom line is that I'm staying the course for now but I'm open to wherever and whatever God leads me to. Life is an adventure, and I see now that the greatest adventure may not be in the direction of my boyhood passion. But it might.<br />
<br />
So what's this blog gonna be about this year? Honestly I don't know. I found as an intern that I couldn't really post about aerospace because everything I was doing was proprietary, and that's still true for the most part. Perhaps the deep theme has yet to unfold. You'll just have to keep reading to find out.</div>

<br />
I recently decided to be more serious about learning a new language, and between the two that I already am familiar with, Chinese and French, I chose Chinese. My goal is to become fluent within six months, so we'll see how I've progressed by September 1st.<br />
<br />
I've learned that the best way to learn a new language is just to speak it, mistakes and all. The best thing about being a college student is that there are many, many international students to practice with. I have already made several friends this semester.<br />
<br />
Learning Mandarin is not half as hard as it is made out to be. Yeah, you have to watch your tones, but even that is pretty easy once you get a feel for it. But the grammar and vocabulary make so much sense and are much simpler than western languages. For instance, no verb conjugation or tenses, no masculine/feminine shenanigans, etc. Where it is difficult, however, is character recognition. But thanks to pinyin, the Romanized system of spelling Chinese, I don't have to worry about it until later.DTH Rockethttp://www.blogger.com/profile/09222212036229618785noreply@blogger.com3tag:blogger.com,1999:blog-1644326416987696055.post-71383247960192748882014-01-17T14:39:00.000-08:002014-01-17T14:39:19.980-08:00It's Been A Looong Time...<div style="text-align: justify;">
Hi there,</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
This post is meant to be an update on Daniel Hastings and his continuous upward climb to cool things in the sky. As you may know, I spent the last year in California working with XCOR on the Lynx. I decided to keep blogging to a minimum during this time, because it was all so proprietary, and besides my work for XCOR there wasn't much to say. But I'm back at school now, and I have three semesters before I graduate with a degree in aerospace engineering from Iowa State. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
In this post I wanted to share with my readers what I've been learning lately, and not just about engineering. About life, too. I've been learning a lot, I think, and this post is a collection of these thoughts rather compartmentalized in neat little rows.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b>The little things are just as important as the big things... if not more.</b></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
This is something I've come to realize lately. By little things, I mean boring trivial little ho-hum stuff. Life is made up of a bunch of little things, and life is certainly important. What I may shrug off as not interesting or of diminutive importance may have a lasting impact on somebody else. All the little things add up to one big thing of who you are. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Now, in another sense, as an engineer the little things are important for more obvious reasons. Historically the little things bring down big things. One overlooked detail can have catastrophic ramifications. It's why engineering is so hard, and it's why I, as a generality person, have tried my hardest to become a detail person. I don't want the Lynx to go down because of something I forgot about inside the landing gear. *Shudder.*</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b>Do things right the first time.</b></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
It sounds obvious to say, but doing a job halfway with intent to polish it up later is probably going to lead to much pain down the road. For instance, there was one occasion where I wanted to show an engineer a concept that I had for something. So I threw together a rough engineering drawing of my design, not worrying about proper drawing etiquette or proper dimensioning and tolerancing or anything. So the drawing got passed around a bit and then came back to me: We can't make this like this! Look at these sloppy dimensions! Lines everywhere! Give this to the machine shop and they'll say "silly intern, go sit in the corner!" </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
I'm also a writer, as well as an engineer. Now, this goes against everything they will tell you in National Novel Writing Month (www.nanowrimo.org), but I say write it right the first time, or every time you think about your atrocious story you will want to just soak it in HCl and then take a flamethrower to it. I wrote two books during my internship, and... I squirm every time I think about them. You wanna read it? Send me an email!</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<b>Live with eternity in mind.</b></div>
<div style="text-align: justify;">
<b><br /></b></div>
<div style="text-align: justify;">
What...?</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Life is a short paragraph prefacing a very, very exciting, never ending novel called heaven. Do you know what heaven is meant to be? The infinite, never-ending, humongous and powerful God who made everything, who is actively involved in holding the universe together, whose glory is so big I can only see shadows of it rather fleetingly (being manifested in some of the most glorious moments of my life), THAT God wants to have a beautiful, never-ending relationship with you, forever in his kingdom. It's hard to know exactly what life should be about, then, except in this frame of mind. Life is about glorifying God and enjoying him forever. We have Jesus who knows us so intimately--there is no suffering on earth that he himself has not suffered. Why? I dunno. But he loves me and gave his life for me, so that's what I'm going to make mine about. All the other stuff of life really won't last past the first page of the novel, so I'm going to go all in and give it all for my savior Jesus. When I'm alone, when I'm hurting, when I'm afraid, when I'm failing, when I lose and when I'm filled with guilt, I have Jesus as my closest friend, constantly, always there. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Here is how C.S. Lewis imagined eternity, from the ending of "The Last Battle":</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
"And as for us, this is the end of all the stories, and we can most truly say that they all lived happily ever after. But for them it was only the beginning of the real story. All their life in this world and all their adventures in Narnia had only been the cover and the title page: now at last they were beginning Chapter One of the Great Story which no one on earth has read: which goes on forever: in which every chapter is better than the one before."</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Higher up and further in. Every year it's cooler. </div>

I have been looking forward to an Ender's Game movie for a loooooong long time. Finally they have made one.. Terrified to see it, because it would be so easy to turn Ender's Game into something it's not. Also the story is rather disturbing and a literal translation to the big screen would most likely earn a thumbs down from me. I hope they are subtle. That's like saying I hope it will rain in the Mojave Desert. But I can hope.<br />
<br />
P.S. I'm writing a book right now.

The flight was a complete success! They did a 15 second burn on their hybrid engine and reached supersonic flight.<br />
<br />
My coworkers had written down Scaled's frequencies and were listening in on their communications during the flight. It made for a wonderful narration for the video.<br />
<br />
All those years of tracking model rocket flights paid off and I took a rather nice shot of the drop and ignition, all the way from nearly 50,000 feet:<br />

I watched White Knight II flying around with SS2 in tow, but I didn't get to see SS2 glide in by itself. They tend to do their drop tests early in the morning before I get in to work.<br />

Earlier this April I went out the the F.A.R. site for some fun experimental rocketry. Before I got there apparently there had been a hypergolic rocket test of nitrogen tetroxide and hydrazine (for those of you that don't know, these are some VERY dangerous chemicals!) Another guy had put together a baby P-class motor (pictured above). As I watched it fire, I realized that I have been spoiled on XCOR's Lynx engine (each engine produces 3000 lbs of thrust with a maximum duration of 3 minutes!). Previously I would have done a backflip to see a P motor but now I feel rather indifferent. In a way it's kind of sad, but at the same time it also goes to show how awesome life is right now.<br />

I had the interesting experience the other day of attending a wild Yuri's Night party under the Shuttle Endeavor, as a VIP from XCOR. VERY interesting experience being on the same VIP list as Buzz Aldrin and Bobak Ferdowski (The Mohawk Guy... surely you remember him from the Curiosity landing and memes all over the internet), plus we're <i>partying</i> under the <i>Space Shuttle</i>. Need I go on??<br />

I'm thrilled that XCOR has finally released a press release on this topic so I can finally open my blabbermouth (but even now I have to check what I say so that it doesn't give away more objective information than the press release itself does).<br />
<br />
Awesome epicness. That's what this is. I was there in the bunker for that hotfire. Now I fully know what people mean when they talk about a "Peenemunde Minute." It felt like an hour. An hour of sitting on a stool in a bunker, forgetting how to breath, and wondering if that thunderous roar is going to vibrate me onto the floor.<br />
<br />
That's about all I can tell you. And this video is about all I can show you. So enjoy!<br />

After Plane Crazy, my goal was to find the Friends of Amateur Rocketry (FAR) launch. All I knew was that they were at the "East end of Koehn Dry Lake." With a little Googling I was able to find the site in no time. </div>

I'm hoping to get involved with a project called "Sugar Shot to Space" (SS2S) while I'm out here in Cali. SS2S's goal is to build an amateur rocket that reaches space using good ol' rocket candy for propellant. I'll keep you posted on how involved I get, but for now I recommend checking out their website to learn more: <a href="http://sugarshot.org/">http://sugarshot.org/</a></div>

As expected, I arrived way late just as everyone was leaving, but it was a fun trip anyway. If I thought I was in the desert before, I was <i>really</i> in the desert now. There were dunes that were drifting up onto the road in places. It felt less like the Mojave and more like the Sahara. </div>

That is, Plane Crazy, a periodic event at the Mojave Spaceport where people will show off their airplanes that they've built or collected and just hang out. The main event was a presentation on rocket photography by Mike Massee, XCOR's photographer/videographer. It was fun going to the Spaceport on a Saturday, just chilling, setting up the Lynx model and showing people around. My co-intern Parag and I got to play around with the Lynx when there was nothing else to do. This thing is an epic full-scale mock-up of what the Lynx will actually be, and instills great inspiration for space travel in whoever climbs into the cockpit. Not having ever even flown in a rocket powered vehicle before, I already have the "Rocket Grin:"<br />

(I'm told the above is an F18. You can't expect a rocket scientist to know all the airplane names).<br />

It was a packed day! After Plane Crazy I decided to try another Miniadventure and find some Amateur Rocketeers... (Stay tuned for the next post)<br />

They actually had some issues with the thrusters after launch, three of the four thrusters were not operational. The spacecraft could still function with two thrusters offline, but NASA wanted at least three up and running before attempting to dock. It apparently was a software issue and they got it worked out in the end. Congrats SpaceX! Looking forward to the day when you can bring people up, too!<br />

Manned Mars Mission by 2018!Inspiration Mars Foundation is planning a manned flyby mission to Mars for a target launch date of January 5, 2018. The announcement was made today.<br />
<br />
A fast, free-return mission is similar in function to the Apollo 8 mission. The idea is to send two private U.S. citizens (probably a married couple, actually) on a 501-day mission to flyby the Martian surface by 100 miles and then return safely to Earth.<br />
<br />
I like the patriotic nature of this mission, billed as "A Mission for America." I know it isn't very "politically correct" considering the fact that idealistically access to space is something that all nations should aspire towards and the collaboration between nations is a virtue extolled by Star Trek and other popular ideals, but I don't care. I still like America best.<br />
<br />
I completely agree that now is as good a time as any to visit the red planet. It's been technologically possible to achieve this mission ever since the technology of Apollo. But we've just been waiting for someone to take initiative. That initiative came from Inspiration Mars.<br />
<br />
Check out this factoid sheet on the preliminary mission specs: <a href="http://www.inspirationmars.org/Inspiration%20Mars%20Fact%20Sheet.pdf">http://www.inspirationmars.org/Inspiration%20Mars%20Fact%20Sheet.pdf</a><br />

Heretofore they have been referred to as "P4" and "P5" and I think scientists are getting tired of such boring nomenclature.<br />
<br />
I voted for "Cerberus" because I am in the middle of playing Mass Effect 3 and enjoy links between science and popular culture. Of course, the science people were probably thinking of the three-headed dog that guards the gates of the Underworld, not the pro-human terrorist group, but that fits, too.<br />
<br />
Another option I almost went with was "Vulcan," but I feel obligated to save that name for a distant planet filled with green-blooded logical pacifist pointy-eared hobgoblins.DTH Rockethttp://www.blogger.com/profile/09222212036229618785noreply@blogger.com0tag:blogger.com,1999:blog-1644326416987696055.post-46187602137235999942013-02-18T14:53:00.000-08:002013-02-18T15:00:15.155-08:00Friendly Reminder to DO HARD THINGSWhile my life in general seems to exude the notion that it isn't going to waste, and while picking a tough major and moving halfway across the country for a tough internship can be considered "doing hard things," a close look at how I've spent my free time lately would reveal a distinct lack of productivity. I looked at my list of project ideas this morning. It is extremely long. I have not completed a single one all year. What have I been doing in my free time? Absolutely nothing.<br />
<br />
I'm borrowing this rallying cry from my friends at <a href="http://therebelution.com/">theRebelution.com</a>, whose banner has graced the bottom of this webpage since the history of this blog: a call to rebel against low expectations for young people and to Do Hard Things. While I am no longer a teen, the temptation to slack off and retreat into my own little world hasn't desisted. I want to do something other than for myself. I'm going to start small. I've noticed I have the ability to post educational videos on YouTube. That is my Start Here.<br />
<br />
I hope God will use me to help bring light into this world.<br />
<br />
"You are the light of the world. A city set on a hill cannot be hidden. Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven."<br />

Fun news.
<br />
<br />
<blockquote>
Commercial spaceflight is entering the main stream and looking (and smelling) quite good! United Kingdom-based Unilever Group (NYSE: UL, Unilever N.V. and NYSE: UN, Unilever PLC), and Space Expedition Corporation (SXC) announced a 22 flight purchase on XCOR Aerospace's Lynx® Mark II suborbital spacecraft for Unilever's space-themed AXEApollo™ campaign for the AXE ® brand of men's cologne, body spray, shower gels and other personal care products.<br />
<br />
Unilever will award the first flight to a lucky winner selected from a drawing just after the Super Bowl on February 3rd, and the 21 other winners will come from a year long, 60 country promotional campaign. That larger campaign includes a 100+ person December 2013 space camp for early stage winners in Orlando called the AXE Apollo™ Space Academy (A.A.S.A.). The campaign also includes legendary Apollo astronaut Buzz Aldrin and a 30 second Super Bowl advertisement. For a chance to win, register at www.AXEApollo.com.<br />
"When a global brand leader like Unilever makes a significant commitment to a product like our Lynx®, it is a clear sign that commercial spaceflight has entered the main stream of worldwide commerce and truly is the Next Big Thing," stated Andrew Nelson, Chief Operating Officer of XCOR Aerospace, "Expect to keep seeing more good news from SXC as they ramp up in 2013!"</blockquote>

While I would love to tell you about all of my experiences the next six months, I will have to speak in very general surfacy terms when talking about XCOR for obvious reasons. But you will hear all about my adventures in Mojave and Lancaster and of course my own personal projects (thinking very seriously about level 3, and I'm going to try and find a high-power rocketry club out here!)<br />
<br />
Me and the two other interns are sharing an apartment in Lancaster. It is very nice, with three bedrooms, two bathrooms, a kitchen and a wide-open living room. We bought some cheap furniture at Goodwill to fill up the empty void. As far as the other two interns go, I think we're going to get along great! Time will tell.<br />

<br />
<br />
I am in possession of a level 3 casing. Can anyone guess what this means for 2013? This means that I am going to go for my level 3 certification! Finally! This is going to be my main project for 2013, and it will enable me to fly rockets on M-O impulse. Now, I know what you're thinking... You're a poor college student. How are you going to afford to be a level 3 flier? The answer to that is quite simple. First of all, this is a borrowed casing from the Iowa State Space Society (Thanks guys, even though you didn't even know you had this casing in the first place!). So all I need to buy are the rocket parts and the reloads. Still kind of pricey. But future projects are going to be primarily funded by my university, including Rockoon. The goals for next year are to build a two-stage rocket using this casing for the first stage and a baby-N load, and the 75mm Cesaroni casing in the second stage with a baby-M load. Initial Rocksim predictions say that if we launch from a balloon at 80,000 feet we would hit the very edge of space.<br />
<br />
Space.<br />
<br />
But I'm not going to do it without help. I'll need a team. Just a few members with strong and diverse skills. Nimble and adaptable to any situation. We'll need resolve, because space is hard. That is why we do space.

See the pretty picture of the Iris Nebula that I took? This is the result of endless hours of work. It goes with a 15-page report about the photometry of the surrounding stars, the flux ratios in different bands of the nebula, and other random science stuff. I enjoyed this class, but I know now that astronomy is not my cup of tea. It's a rather passive form of space exploration, and I'd much rather work on the vehicle to get there.<br />

<br />
Spin stabilization has been a concept that's been around in rocketry for a long time. But just how fast can you spin a rocket, and just how far can you benefit from it? Do you even need fins at all if you get it spinning fast enough? Take a look at a bullet, for example. It has no fins. It is, however, exiting it's "launch tube" at supersonic speeds, but perhaps this can be related to rocketry.<br />
<br />
I imagined a launch pad that uses an electric motor to spin the rocket extremely fast, say... 1000 rpm. One point of concern is the electrical leads for the igniter. You would need to use some sort of conducting bearings, or even an onboard ignition system triggered wirelessly.<br />
<br />

<br />
<br />
Just a thought.<br />
<br />
The main question I would like to look into is: Can spin-stabilization be effective enough to have a rocket with no fins? At what angular velocity? With what kind of rocket geometry?DTH Rockethttp://www.blogger.com/profile/09222212036229618785noreply@blogger.com7tag:blogger.com,1999:blog-1644326416987696055.post-42064695582931086422012-12-01T18:30:00.000-08:002012-12-01T18:31:13.769-08:00Lawn DartSometimes you just have to take a break from studying and launch a rocket. This can lead to misadventures. For example, a few friends and I went out to launch some rockets out in the cross-country fields. Thought they were big enough to launch a G motor. Turns out there was a neighborhood not too far from there. My rocket came in ballistic in a neighborhood.<br />
<br />
I got pretty lucky. Usually rockets aim for the ONE tree or the ONE creek or whatever ONE thing in the middle of a wide-open field you don't want to land in. This time, however, I hit the ONE patch of grass in a sea of pavement, cars and houses.<br />
<br />
Phewf.<br />
<br />
The upper portion separated and drifted somewhere, so I didn't even bother looking for it. But when I got home, I had an email from one of my classmates whose roommate had found the rocket, and he's bringing it to class on Monday.<br />
<br />
Huh. Maybe I should go buy a lottery ticket.<br />

<span style="font-family: Times;">The concept of a </span><span style="font-family: Times;">Rockoon </span><span style="font-family: Times;">was
first developed in 1949 by the </span><span style="font-family: Times;">Aerobee</span><span style="font-family: Times;"> Rocket engineering crew and </span><span style="font-family: Times;">consisted </span><span style="font-family: Times;">of
a sounding rocket that </span><span style="font-family: Times;">was
launched </span><span style="font-family: Times;">from a balloon, rather than from the
ground to achieve higher altitudes. James Van Allen was the first to use the
rocket-balloon combination to study the atmosphere in 1952. In 1953 </span><span style="font-family: Times;">Rockoons</span><span style="font-family: Times;">
fired off Newfoundland </span><span style="font-family: Times;">detected
</span><span style="font-family: Times;">the first hint of radiation belts
surrounding Earth. The low-cost Rockoon technique was later used by the Office
of Naval Research and The University of Iowa research groups in 1953-55 and
1957, from ships in sea between Boston and Thule, Greenland.</span></div>

Platform Design</span></span></div>
<span style="font-family: Times;">The </span><span style="font-family: Times;">launch
platform is essentially the fundamental component of a Rockoon system, as it is
the part the actually connects high powered rocketry with high altitude
ballooning. The platform needs to be durable and lightweight, but </span><span style="font-family: Times;">able to </span><span style="font-family: Times;">house
the rocket and electronics, and be able to successfully launch the rocket.
The platform will be a “cannon” like design connected to a multiple
balloon system, with the rocket sitting in the middle of the platform
surrounded by three side rails. These side rails will hold the rocket in
place while it’s being towed to launch altitude, along with keeping the rocket
stable while it reaches a sufficient launch velocity. The platform will
also house electronics that will allow us to track the platform and actually
communicate with the rocket prior to motor ignition.</span><br />

<span style="font-family: Times;">The electronic systems for the launch
platform have to perform four basic functions: (1) Monitor </span><span style="font-family: Times;">the motion of the launch </span><span style="font-family: Times;">platform, </span><span style="font-family: Times;">(2)
Receive command to launch the </span><span style="font-family: Times;">rocket,
(3) Track the launch platform via GPS, and (4) after ignition of the rocket,
cut-down from the balloons so that the platform would return to Earth. The
first flight of the launch platform will be to test the reliability of the
launch platform and electronics without the launch of a rocket. Several cameras
will monitor the motion of the balloons and the platform. An onboard
accelerometer and gyro sensor will record motion data to an onboard micro-SD
card. These functions, along with the ignition and balloon cut-down will be
controlled by an Arduino MCU, and are depicted schematically in the figure
below.</span></div>

<span style="font-family: Times;">The rocket design is based off of a
carbon fiber airframe that was passed down to us from our predecessors. It will
be a minimum diameter rocket that is just over eight feet tall made completely
of carbon fiber. The nose cone has a metal tip to help burst through balloons
if needed. This rocket will be flown on
a </span><span style="font-family: Times;">Cesaroni</span><span style="font-family: Times;">
4-grain, level-two L motor. Payloads
will consist of a GPS, CO</span><span style="font-family: Times; vertical-align: sub;">2</span><span style="font-family: Times;"> </span><span style="font-family: Times;">pressure ejection system for
recovery, an accelerometer, and a camera
with the possibility of a live video stream.
Initial </span><span style="font-family: Times;">RockSim</span><span style="font-family: Times;"> simulations predict a maximum altitude
of 157,000 feet, and a maximum velocity of 2427 feet per second (Mach
2.4). </span></div>

<span style="font-family: Times;">The design for this rocket has a center
of gravity of 76.7 inches and a center of pressure of 91.8 inches, giving a
static margin of 4.8 caliber. If the launch were to occur from the ground this
margin would be too high, but since the launch will occur at higher altitudes,
the perturbing effects will be much less effective due to the lower air
density. Due to launching at high altitudes, bigger than normal fins will be
used and an exit velocity of about 150 feet per second from the platform will
be needed for stable flight.</span></div>
