Congress is at it again....SLS underfunded.

Well, here we are again.  For some reason, Congress cannot fund a rocket once it demands it.  Congress should desist from demanding rockets from NASA.  Somebody please sue Congress for overstepping their constitutional bounds.

On July 23rd, 2014, the Government Accountability Office (GAO) said that NASA didn't have enough money to complete the Space Launch System (SLS) in time for the 2017 first launch of the rocket according to Marcia S. Smith's of SpacePolicyOnline.com article entitled "GAO Warns NASA $400 Million Short to Finish SLS by 2017" (click here to see article).  What the hell?

The NASA Authorization Act of 2010 "required immediate development" of the SLS.  Where does it say in the Constitution that Congress can require development of anything?  Such a demand would lie in the executive branch of government, not the legislation.  Well, legally I'm sure I am wrong here, but logically I am right.  NASA, DARPA, and other government research agencies ought to be directed by the executive branch only and not by the legislative.  The reason is obvious, research drives military power and economic health of the nation.  Yes, it's national security.  See, I think economic health should be a part of national security and not just national secrets.  Yet, we have to live with these short sited authorization acts.  Ideally, any legislation authorizing money to a very large project ought to grantee funding for the projected life of the porject.  But the authorization act of 2010 only gave money to 2013. What the hell! 

 I knew this was coming, and when it came I still felt mad and betrayed.  This is exactly why we are not further in our space program as we expected to be.  This questionable way of financing large NASA projects puts into question Congress' concern for the nation's welfare.  This system is broken.  It needs to be redone, rethought over.  I think its time for the US people to start thinking of better ways to proceed in space.  The space research has expanded to a point where there is more space projects than there is available money.  There are commercial alternatives now to launching spacecraft.  There are new spacecraft designs with cost in mind.  Tell Congress to grow a brain and get smarter about space.  It's no longer about jobs in a particular state.  It's about the economy as a whole benefiting from research that is waiting to be done.

Warp Theory

We have a warp theory.  We have a warp theory.  I still can't wrap my head around it.  Thanks to Einstein, and some very intelligent Star Trek fans who became scientists, we have a warp theory. Check out the following video put out by Huffpost UK.  If your a Sci-Fi fan, a space enthusiast, a math student, science fan, or even if you have a heart beat watch this video.  Caution, your mind will be blown.




Far out, man!  What this means is that we are tinkering with the math model to find the best engineering model.  It's warp theory in the making.  

You too can tinker with the numbers.  Download Dr White's pdf document entitled Warp Field Mechanics 101.  If you don't understand it all, at least you know where you stand in learning this level of math and physics.

IXS Enterprise - artist envisioned warp ship
Things like this are reasons why we so desperately need students to go into Science Technology Engineering and Math (STEM) fields.  Sure, the economy doesn't look great or even good now.  But were talking the future.  We need to make the future.  The first ingredient to make a great future is always enthusiasm.

As an added bonus for the public, Dr White got together with artist Mark Rademaker to produce a pic of what a warp capable ship could look like according to the math of the warp theory.  They called the ship IXS Enterprise.  How cool is that?

Could Atlas V Days Be Numbered?

Atlas V
The Atlas V was derived from what is called the family of Atlas rockets.  This family started launching in 1957, so Atlas V has a great heritage.  It has also been the main workhorse launcher for NASA and USAF satellites for about 12 years now.  As such, it was a rocket that was built strictly on government money.  It is now under scrutiny because its main engines, RD-180, are from Russia and Putin's administration is threatening to stop providing them.  The response to this is that the US government will put up money to research a new engine.  Wow!  Taxpayers are still paying full price for this rocket system.

With the advent on NASA COTS (commercial orbital transportation services) and CRS (commercial resupply services), the taxpayer has been getting a break.  NASA invested some money for the development of two launch vehicles and spacecraft from two different companies; SpaceX and Orbital Sciences.  These companies paid the rest of the development and own the risk for each launch.  In contrast, United Launch Alliance owns no risk to the Atlas V launches.  NASA deems the COTS and CRS programs successful and successful at reducing launch costs.  Will Atlas V survive in such a stark contrasted means of doing launch business?

Now, the Antares rocket is in a similar predicament with its main engines as Atlas V, though for different reasons.  The Antares main rocket engines are from the old Russian N-1 rocket, and those are of limited supply.  So Orbital Sciences is seeking a new rocket engine as well.  The difference is that they are flipping the bill themselves.  After all, they own the rocket.

 So we can see the inconsistencies for the taxpayer.  On one hand we have the old way of paying for the rockets as in Atlas V's case (the so called Cost Plus contracts).  That is, taxpayers pay for the launcher development, the launch service, and the launch risk.  Doing things the COTS and CRS way (services contracts), taxpayers only partially paid for initial development and for each launch service.  They don't pay for further development nor for the launch risk.

If the USAF got on board with paying only for launch services, they could save a lot of money, have companies competing for launches, and have national security all at the same time.  Sounds like the holy grail for the Department of Defense.  In my opinion, this would require a major change to EELV or even a replacement.  My reasoning is that the word 'expendable' might become a thing of the past since SpaceX is actively developing reusable multistage rockets.

I highly doubt that Atlas V could be converted to take on contracts for launch services only.  The reason is that it was developed under the attitude of limited savings as opposed to the drastic savings now sought after by the US.  No, Atlas V would have to be retired.  Of course engineers are pretty crafty guys.  If, by chance, Atlas V becomes reusable then I will rethink my position.  Otherwise, you really need to design a rocket with cost effectiveness in mind like Falcon 9 and Antares.

Now, SpaceX's Falcon 9 and Orbital Sciences' Antares do not have the lifting capabilities on Atlas V.  So for now, the USAF and NASA needs Atlas V.  Future developments from SpaceX and Orbital Sciences could change all that.  SpaceX is planning to make the Falcon Heavy which will eclipse the Atlas V by a factor of __ in launch capability.  Orbital Sciences is creating the rocket for Startolaunch that will go after the Delta II payload market.  Could there be any more developments in affordable launch vehicles?  I would say yes as long as the market holds up and funds become available.  In such a case, we may see the end of the Atlas family.  Atlas V still needs to get over a couple of hurdles.  One is, as mentioned before, getting new main rocket engines made in the United States.  Another hurdle is the Commercial Crew Development for NASA.  Atlas V is slated to carry one of two crewed vehicles to space: Dream Chaser lifting body by Sierra Nevada, and CST-100 capsule by Boeing.  What would the pricing be to take these to orbit by Atlas V?  Will such pricing be competitive?  Will such pricing be acceptable by NASA?  In other words, can Atlas V compete with Falcon 9 in the market?
