At the end of six years of free period, everything in Oregon government establishment, including simple websites will be using Oracle DB & systems, resulting in huge ongoing revenue for Oracle.
The reason is simpler, actually. The stage has significant horizontal velocity because it is coming back from too far away. There is a boost back burn right after MECO which reverses the direction the stage is going. It is not practical to move it horizontally at that speed while keeping it vertically straight (too much wind resistance can break the stage). So it has to lose both horizontal and vertical velocity at the exact moment of touch down, while straightening up at the same time. Straightening and stabilization of the rocket is done by a combination of reaction control thrusters, grid fins, and the landing burn of the central engine. The points you raise are also valid of course.
If you and I are given the same resources as Jobs, could we have created a Mac or iPhone? Jobs' greatness is not because he was a great inventor (though media simplifies it to that). But it is the ability to put all the resource available to him to realize a dream. I say this even though I am not a fan of Jobs or Apple. Quite the opposite.
Same applies to Musk. Of course he was utilizing government subsidy as much as possible for Solar City and Tesla. Of course Falcon 9 and Dragon received significant government funding. But most of his competitors have the same resources available to them to even larger extent. Why weren't they able to produce a product that is as successful? It is in the ability to dream, and put together what he has to realize it.
I have been a programmer for all of my career, and had management roles in the past 10 years to varying degrees. Over this period, I have also mentored other technical team members in transitioning to management roles. The toughest part of that process is in learning the ability to delegate. This is especially tough for talented programmers.
You often feel that it is easier for you to do a particular task yourself rather than delegating. It may be true that you might finish the work in tenth of the time it takes someone else to do, and you may be spending more time in explaining it to others. But at some point you have to stop doing it, start trusting others to deliver, and don't meddle with their work too often. Once you learn how to do it, you are well on your way to becoming a successful manager.
Get real man. Shuttle might have cost a bit higher due to politics, but it was never going to be cheap - just as SLS is not going to be cheap. Shuttle should have been abandoned at least in 1986 when they realised that they forgot to put a launch abort system on it.
Over its lifetime, it has cost $209B. That is over $1.5B for each flight.
Hmm... may be it will look cheaper by 2025 when you are spending over $10B on each launch of SLS (It is expected to cost $41B for 4 flights by that time). Hopefully someone would have mercy and kill it before then.
ISRO never called it a shuttle. It has always been refered to as technology demonstrator (RLV-TD). Current experiment is termed RLV-TD HEX (Hypersonic flight Experiment). The ultimate aim is to develop an RLV named Avatar, which was originally announced over 17 years ago.
This particluar test flight should not be compared to US space shuttle. Better comparison would be X-43A or X51-A Waverider. As these have defence applications, the projects had been running between NASA and DARPA. Similarly, India's Avatar programme has also been shuttling between ISRO and DRDO (Defence Research & Development Organization).
The main feature of Avatar concept is an air breathing Scramjet engine. So far there hasn't been any great success in developing Scramjet engine. The longest one fired for 15 seconds on second flight of X-51A, while its first flight didn't run scramjet. India is nowhere near developing Scramjet in immediate future. But the current flight will test some preliminary technologies related to that project, specifically hypersonic reentry. I don't think this particular vehicle has any propulsion. Even the next two experiments planned on the series (LEX and REX) are planned without any rocket propulsion, but will use turbofan engine for landing. Actual powered flight would be on the SPEX, which will use Scramjet (Source: http://isp.justthe80.com/launc...
Current test is a 100 crore INR (about 16 million USD) experiment. I am happy that ISRO is doing something to take this promising technology further. It may take another 20 years before actually seeing a scramjet engine in action, but that is ok. I would consider it as my tax money well spent.
Can we turn this around and say, "ability to think in multiple perspectives is important to successfully learn a new language"? There are many for whom learning a second langauge is very difficult while some others pickup a new one easily. Would this theory explain that problem?
Landing on a barge (or ASDS) would still be needed for deep space missions like DSCOVR which didn't have enough fuel left to boost back the stage towards launch pad. The center core of Falcon 9 Heavy wouldn't have enough fuel as well, and will most likely land on ASDS, while other two booster cores go back to landing pad.
SpaceX is in fact building a second ASDS which will be used for launches from Pacific coast.
There are plenty of products in the audiophile industry that can match or exceed this in craziness level. I wouldn't be surprised to see a glorifying review of this in a hi-fi magazine.
Better launch countdown where you can see in your local time (click on the globe). Looks like the launch moved to Tuesday night (EST) now.

This doesn't make a dent in cost effectiveness of Falcon 9 or PSLV.
Let us calculate per pound LEO costs for these vehicles:
ALASA: $1M / 100 lb = $10,000 / lb
Falcon 9: $61.2M / 28,991 lb = $2,111 / lb
PSLV: $20M / 7170 lb = $2,789 / lb
Tiny satellites at 100lb can easily tag along with bigger launches on these vehicles. Costs may be even cheaper for such secondary payloads or may even free in some cases. If SpaceX succeeds in first stage reuse, or ISRO per chance succeeds in RLV-TD plans, costs may come further down.
So ALASA sounds like a costly option for small satellites today and in future. But the technology as such may have potential if handled by a better managed private company that works on it as a commercial venture.
