Why the US Can Beat China: A SpaceX Story

A letter from Elon Musk:

Whenever someone proposes to do something that has never been done before, there will always be skeptics.

So when I started SpaceX, it was not surprising when people said we wouldn’t succeed. But now that we’ve successfully proven Falcon 1, Falcon 9 and Dragon, there’s been a steady stream of misinformation and doubt expressed about SpaceX’s actual launch costs and prices.

As noted last month by a Chinese government official, SpaceX currently has the best launch prices in the world and they don’t believe they can beat them. This is a clear case of American innovation trumping lower overseas labor rates.

I recognize that our prices shatter the historical cost models of government-led developments, but these prices are not arbitrary, premised on capturing a dominant share of the market, or “teaser” rates meant to lure in an eager market only to be increased later. These prices are based on known costs and a demonstrated track record, and they exemplify the potential of America’s commercial space industry.

Here are the facts:

The price of a standard flight on a Falcon 9 rocket is $54 million. We are the only launch company that publicly posts this information on our website (www.spacex.com). We have signed many legally binding contracts with both government and commercial customers for this price (or less). Because SpaceX is so vertically integrated, we know and can control the overwhelming majority of our costs. This is why I am so confident that our performance will increase and our prices will decline over time, as is the case with every other technology.

The average price of a full-up NASA Dragon cargo mission to the International Space Station is $133 million including inflation, or roughly $115m in today’s dollars, and we have a firm, fixed price contract with NASA for 12 missions. This price includes the costs of the Falcon 9 launch, the Dragon spacecraft, all operations, maintenance and overhead, and all of the work required to integrate with the Space Station. If there are cost overruns, SpaceX will cover the difference. (This concept may be foreign to some traditional government space contractors that seem to believe that cost overruns should be the responsibility of the taxpayer.)

The total company expenditures since being founded in 2002 through the 2010 fiscal year were less than $800 million, which includes all the development costs for the Falcon 1, Falcon 9 and Dragon. Included in this $800 million are the costs of building launch sites at Vandenberg, Cape Canaveral and Kwajalein, as well as the corporate manufacturing facility that can support up to 12 Falcon 9 and Dragon missions per year. This total also includes the cost of five flights of Falcon 1, two flights of Falcon 9, and one up and back flight of Dragon.

The Falcon 9 launch vehicle was developed from a blank sheet to first launch in four and half years for just over $300 million. The Falcon 9 is an EELV class vehicle that generates roughly one million pounds of thrust (four times the maximum thrust of a Boeing 747) and carries more payload to orbit than a Delta IV Medium.

The Dragon spacecraft was developed from a blank sheet to the first demonstration flight in just over four years for about $300 million. Last year, SpaceX became the first private company, in partnership with NASA, to successfully orbit and recover a spacecraft. The spacecraft and the Falcon 9 rocket that carried it were designed, manufactured and launched by American workers for an American company. The Falcon 9/Dragon system, with the addition of a launch escape system, seats and upgraded life support, can carry seven astronauts to orbit, more than double the capacity of the Russian Soyuz, but at less than a third of the price per seat.

SpaceX has been profitable every year since 2007, despite dramatic employee growth and major infrastructure and operations investments. We have over 40 flights on manifest representing over $3 billion in revenues.

These are the objective facts, confirmed by external auditors. Moreover, SpaceX intends to make far more dramatic reductions in price in the long term when full launch vehicle reusability is achieved. We will not be satisfied with our progress until we have achieved this long sought goal of the space industry.

For the first time in more than three decades, America last year began taking back international market-share in commercial satellite launch. This remarkable turn-around was sparked by a small investment NASA made in SpaceX in 2006 as part of the Commercial Orbital Transportation Services (COTS) program. A unique public-private partnership, COTS has proven that under the right conditions, a properly incentivized contractor — even an all-American one — can develop extremely complex systems on rapid timelines and a fixed-price basis, significantly beating historical industry-standard costs.

China has the fastest growing economy in the world. But the American free enterprise system, which allows anyone with a better mouse-trap to compete, is what will ensure that the United States remains the world’s greatest superpower of innovation.

NASA Makes Breakthrough in Sonic Boom Reduction

Image

It has been publicly known that NASA has been testing methods to reduce the sonic boom signature of jets. Tests have been underway with Boeing and Lockheed Martin to achieve this goal and it was just released that their has been a “breakthrough” in testing!

Quoted from a NASA representative:

“This is a breakthrough. It’s the first time we have taken a design representative of a small supersonic airliner and shown we can change the configuration in a way that is compatible with high efficiency and have a sonic signature than is not a boom,”

2025 could be the reemergence of Concorde-travel. I’d love to feel this “new boom,” because when I was at Edwards Air Force base last month, the boom I experience definitely wasn’t subtle and wouldn’t gain nationwide acceptance.

Either way, great job America!

Reference: AviationWeek

 

Could this possibly be related to the “small earthquakes in Wisconsin?” The boom in the video definitely sounds like the sonic boom I heard at Edwards. Check out the video and tell me what you think.

Top 10 iPhone Apps for College Students

Sometimes I wonder if there’s anyway I could have gotten through school without my iPhone (well I  actually have a month left!). The usefulness of this device can only be defeated by how much it can truly distract you, unless you keep a disciplined list of apps. Below are my recommendations for awesome iPhone apps that helped me get through my engineering curriculum.

1.) Evernote

This has to be hands down the most useful app a college student could every use. With great handwriting recognition, just take a photo of a board from class or a study group and it’s saved, but better yet, you can do a search for a word, and by PFM (Pure Fricken Magic) it can find it. This app is also great for taking notes in class!

2.) Dropbox

I use this app daily! I love having all of my notes and files in one easy place. Now you don’t need to pull out your laptop on the bus to look over a presentation or paper you’re about to submit, just open this app and there are all your wonderful school files!

3.) Wolfram Alpha

Sure I have a Ti-89, but this app can do WAY MORE! It doesn’t just do math problems either. One can get answers for a variety of classes such as economics, chemistry, physics, but it is truly awesome at calculus and linear algebra.

4.) New York Times

One of the best ways to get your brain productive in the morning is to read right away. I read the top headlines every morning to stay current and exercise the mind. A useful app for the boring bus ride to and from class.

5.) myHomework

Tracks homework, classes, projects and tests with ease while syncing information to myHomeworkapp.com for review. Once your class schedule and assignments have been entered, you’ll receive notifications of due dates regarding to your work.

6.) StudyBlue

This app is great for making flash cards for classes, but that’s not all. Someone may have already done the work for you!! This app will find others in your classes and show you the materials that they’ve uploaded. This has saved me a great deal of time, especially in my Material Sciences class, where a ton of flash cards were already created. Profit!

7.) Wikipanion
Against the will of professors throughout the world, Wikipedia stays the primary investigate put a stop to for each university student studying a paper. To enable that entry around the fly, Wikipanion is usually a cost-free app that allows you to remotely search and look into Wikipedia’s seemingly countless database of entries.

8.) iTunes U

This has really come in handy for classes that I didn’t exactly understand even when taking awesome notes and coming to class daily (ok maybe that’s most of my classes). I love all the calculus and physics lectures from MIT here. It really helps having another professor give an explanation for the same material.

9.) Spotify

You have to have music in your life! Whether you’re partying, bored, or studying for an exam, a little music never hurt anyone. In the case of the movie, “Iron Eagle,” it actually helps! I think this is a no-brainer, queue up some classical and soak in the knowledge!!

10. ) Mint

The life of a student revolves around money for many reasons: cars, food, clothing, supplies and many more. This personal finance app is a perfect guide to help students create a budget and stretch their money too. With a budget set, inputting a point-of-transactions will track your overall expenses.

Please let me know what apps have helped you get through College or High School.

Engineering Student Specific Apps

iHandy

On a recent trip to the Jet Propulsion Laboratory (JPL) engineers and scientists even use their iPhone with great success. Pictures here is an engineer using their iPhone to find the inclination of the newest Mars Rover (MSL). Got to love it!

Jet Engine Heaven at Williams International Tour

On Friday March 16th, the AIAA University of Michigan Student section brought 10 students to Williams International in Walled Lake Michigan. If you like jet engines than this was the tour you should have been on! This is also the 10th aerospace engineering company that our AIAA section has visited since January. I’m pretty sure we have the monopoly on cool tours! Go Blue!

The Tour is About to Begin!


Our tour started with some quick seminars to learn a little bit more about Williams. For those of you that haven’t heard of Williams Int., they are the world’s leader in small jet engines. Their jets can be found on many Cessna and Cirrus models, but their main claim to fame was for producing an engine for the U.S. cruise missile.

We had some great lectures from various engineers on the topics of work cycles, combustion, material properties, and testing. The real fun started with a live test of the Williams International F107-WR-105 turbofan engine. After putting on our eye and ear protection, one of the test engineers, who was a recent UofM graduate started up the beautiful little engine. The purpose of the test was to get a final inspection of operation of the engine before sending it out to the customer. We really couldn’t be happier. As you can tell from the picture above this engine is SMALL! Since there isn’t any bypass air to speak of in this gas turbine, this little guy screamed! It was awesome! As we watched the test engineer ramp up the RPMs and take data we were all fixated on the computer screens, which displayed a plethora of information such as exhaust temperature, compressor RPM, and a bunch of other vitals.

Williams FJ44-3ATW

After 10 minutes of drooling, we moved on to yet another test cell! This time we were going to watch the startup of a Williams International FJ44-3A. The previous engine we saw could produce a max thrust of 607 lbf., this much larger engine is capable of 2820 lbf. We were ready for some power! We were in a much larger test room this time, as the engine was much larger. As the engineer ramped the power up to full, we were amazed and the noise and rumbling vibrations, but due to this engines larger bypass ratio, we were spared from the high pitch noises that the F-107 engine produced.

After the live engine tests we were completely satisfied and could have easily left with the fullest of appreciation and enthusiasm, but there was indeed more to see! We were lucky enough to go through most of the manufacturing rooms, where we got our fair share of lathes, presses, and welding machines. We must have seen over 100 engines scattered throughout the facility, most of them being small F-107 engines.

Thank You Williams International for hosting such a great tour. As an engine enthusiast myself, I was extremely satisfied with everything I was able to see. Cheers to you!

My Day at Lockheed Martin’s Skunk Works

One of the most anticipated tours of our Southern California tour series was to Lockheed Martin’s Advanced Development Programs (ADP), otherwise known as Skunk Works. Being a Michigan student, we are engulfed into the legend of Kelly Johnson. Going into our 5 x 7 wind tunnel building is always a stark reminder of why I chose to go to Michigan for my aerospace engineering studies. So as you can imagine, this was a dream come true.

Our destination was a close one. We departed from your hotel in Lancaster and made the 15 minute drive through the desert to Palmdale. With blues skies, sand, and mountains all around us, it was easy to spot the beautifully plain white and blue building that housed the Skunk Works. The entire group was excited for a trip that seemed very impossible.

The Legend of Kelly Johnson

I don’t think anyone in the group could of ever imaged being able to see such an icon of american aviation. The SR-71 Blackbird, F-117 Nighthawk, and the Lockheed U-2 spy plane were just a few of the many secret aircraft to be designed here. This moment had an especially large effect on me because of my profound interest in Kelly Johnson. I’m still awe struck that we were able to go inside…

Enough reminiscing… At 7am we passed a few security check points to make sure there were no terrorists on board. After everything checked out and we parked the vehicles we made our way to our first event of the morning. A group picture in front of Skunk Works! The 16 students and our host posed for a couple shots as we braved the apparently uncommon chilliness that Southern California was experiencing.

Our second activity for the day was to gather in one of the Skunk Work’s meeting rooms. As we walked through the hallways down to our destination we were surrounded by amazing pictures on the wall of past and current projects. In one of the larger entrance rooms we were presented with one of the coolest displays of the day, the six Collier Trophies, which is awarded annually ”for the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year.” My particular favorite was their most recent trophy, which was won due to Pual Belivaqua’s design on the F-35 JSF engine design.

During our time in the meeting room we had some great talks with leading engineers at the company, including one of my favorite aircraft designers, Leland Nicolai. We got a taste for what the Skunk Works looks for in new graduates as well as some rich history of Lockheed Martin.

F-22 Raptor

Our first big tour of the day was especially amazing! The group was guided though the hallways to one of the large hangars, were we were getting an up close look at some new work that was being done to the F-22 Raptor. I’ve been on the production line at Mariette, GA for the F-22 (which was amazing, by the way), but this was a completely different experience. Instead of a bunch of F-22′s everywhere, there were only three, but intricate work was being done to them on the inside. Like no brain surgeon could ever image, panels from this beautiful bird were taken off and the Raptor’s intricately detailed interior was exposed. The room we were in was insanely clean, and unlike production lines, this room was relatively quiet.


P-791 Hybrid Airship

After spending some time with the Raptors, we moved on to an area, which was much more accessible and less “secret” than the F-22s. It was time for the P-791 Hybrid Airship! Most people may think that blimps are dead, but I can assure you that their resurgence into the aviation field is in full swing.  Using the principles from buoyant lift and aerodynamic lift, this aircraft is ultra-efficient… as long as you’re going under 100 mph. I’ll talk more about the P-791′s applications in a later post, for now check out the great video below.

X-55 All Composites Cargo Aircraft

After spending a healthy hour all with the P-791, we were off to the X-55 ACCA. I was excited to see yet another experimental airplane on the same day! The Advanced Composite Cargo Aircraft (ACCA) is an experimental twin jet engined transport aircraft. Its primary role is to demonstrate the new cargo-carrier using advanced composites. On this part of the tour we didn’t get to just stand behind some hefty red tape, no we were going inside! I think the coolest part of being inside the ACCA was seeing and touch all of the composites on board as well as being able to see the pulley system, which controls all the flight flight

controls. We learned that during flight tests the inside of cargo area gets extremely loud. We definitely noticed this, while we were exploring this beauty.

Being able to be at the Skunk Works was great! A trip that I never thought possible. We learned  one important thing from the Skunk Works that day, and that was a quote:

I have learned to use the word ‘impossible’ with the greatest caution. -Wernher von Braun

Aerospace Dream Tour Day 6: Edwards Air Force Base

Today was the last day of tours for our trip and we ended it with a BANG! Quite literally! Since our hotel was close to Edwards Air Force base the group was able to wake up a little later then normal. This week has been filled with early mornings and late nights. Due to LA traffic most of our journeys started at 7am and usually didn’t wind down until after 9pm.

Journey Through the Desert

Being stuck in a 12-person van for the entire week has most of the group on edge at this point. All I can say is image having 11 back-seat drivers critiquing your every move, music choice, and volume level. It really wears down on a person (but I’d still do it over again in a heart beat).

Once we got off the express way and towards the final few miles before the entrance of Edwards, all one can see is the brown and very dry scenery. We turn on the dramatic sounds of, “Flight of the Valkyries,” to set the mood. Large dry lakebeds and a few cacti are all one can see in the distance towards the mountains. Out of nowhere we spot some looping contrails in the clear blue sky. We weren’t sure if we were seeing top-secret technology or not. One moment there would be twirls and loops of contrails and then one moment later, the contrail would disappear.  Now the mood was really set! With out theme music still blasting at full volume we passed the Edwards AFB sign and finally met our escort at the front gate.

We shared this tour with Cal Poly students and all in all I think it was a healthy group. We all boarded an eerie-looking beige bus and started heading to our first leg of the tour. Everyone was very excited and due to the poor weather the last few days, it was evident that flight time was trying to be made up today. Planes were out in full forth. We immediately started seeing T-38s (the air forces main trainer aircraft and the same trainer used in the awesome movie, Top Gun) as soon as we departed from the front gate. Unlike the passed days of our tour we were getting to see airplanes fly!!

Instrumentation

Our first scheduled tour was in instrumentation. We got to see how the instrumentation folk built equipment and displays for testing purposes. The building was littered with orange painted metal boxes with cool displays and wires. We learned that this orange signified that the pieces were testing equipment. Good old-fashioned metal fabrication was used for these displays so that the equipment can handle the high-G environment of a fighter jet.

Electronics is great, but we had a large group of aerospace engineers and we wanted to see planes! We finally got our wish and entered a HUGE hangar. Inside we found a few KC-130 tankers, some T-38s, and a beautiful B-1 supersonic bomber. We’ve all seen these aircraft before, but what made this so cool was that many of the plane’s panels were taken off, displaying to us their complex insides. A frenzy of wires and orange boxes could be seen inside each of the planes.

We ended this segment of the tour by drooling over the exposed B-1 for a healthy amount of time. At this point we are loving the tour, but we keep hearing fighter jets roaring passed the hangar. Every time one flies by our suspicions increase that top jets like the F-35 and F-22 are flying around us and our strategically timed tours are keeping our eager eyes from seeing them.

 

JSF (F-35) Introduction

At this point we were introduced to the F-35 via PowerPoint presentation. We would like to thank Edwards for the great Subway sandwiches we were served for the JSF presentation. We thoroughly enjoyed the pictures and bullet points about the JSF, but we could tell some of the students were starting to get sleepy from the food (none of course were Michigan students, GO BLUE!) and then it happened. BOOM!!! The conference room we were in shook violently. We had experienced our first sonic boom!!! Everyone immediately pepped up. What a cool experience. If only we could have been outside for it, but I’ll take what I can get!

Global Hawk

Most of us have seen a Global Hawk hanging above us in the National Air Force Museum, but to be able to touch and explore this baby up close was a million times better!! The tour guides gave us as much info as they were able, but the repeating hymn of, “That’s classified,” is what we heard most. I really don’t care though, it was great just to be in the large UAV’s presence. We took our group photo in front of the Global Hawk as well (waiting on Edwards to clear it and send it my way). After a little over an hour with the Block20 and Block30 Global Hawks, we were off to the flight line!!!

To learn more about the Global Hawk check out the military facts sheet here.

UM Students in front of the Global Hawk at Edwards AFB

Flight Line

As we made our way to the flight line from the Global Hawk hangar we were pleasantly surprised to see two F22 Raptors taxing extremely close to us on their way to take-off!!! It looked like we were finally going to get our wish of seeing some advanced planes in the air. After a few f16 escorts were in the air and the final clearances were given, we witnessed the two beautiful F22s take off into the distance. It was great to hear how much louder the Raptor was than the Falcon. So awesome!

F16 Armaments

One of our last stops was at the F16 armaments hangar. He we were able to explore quite a few F16s as we were given a tour of the different bombs that are used on the F16 as well as some future bombs that are currently being integrated for use into the F16.

One of the most interesting weapons we saw was the CBU-97 sensor fuzed cluster bomb. This weapon rains fury onto the battlefield as it spits out molten metel, which melts through tank armor. Check out the video for a demonstration.

This marked the final location of our tour. As we rode the bus back to our vehicles we took a leisurely route passed the F35 and F22 hangars to see if just maybe there were any out. With a little luck we witnessed two F35s out and although they were from a distance, it was still breathtaking! It’s feels great to be one of the few people who have every laid eyes on one of these beauties.

Blackhawk Museum

Before heading back to our hotel for the night, we made a quick excursion to the Blackhawk museum located in Palmdale. I got a great shot of the A-12 and SR-71 side-by-side. Lots more pictures to come on my flickr account: Aeroscholar

This was one of the most exciting and truly unique days of the tour. It was great being able to see the JSF and being present for a sonic boom. I don’t know how we made it through the day without a change in underwear.
