Shouldn't NASA's role be more blue-sky research for things we don't know yet are feasible or possible?
Another motivation is a desire to understand the design principles and behavior of such concepts at a deep and general level. That's not usually something industry does—often industry's level of analysis and experimentation is just "good enough" to get a job done. If that gets repeated a few times, it leads to both wasted effort and a proliferation of mediocre designs. (As another example, that motivation also drove the National Advisory Committee for Aeronautics—NASA's predecessor agency—to undertake an exhaustive study of airfoils. NASA still undertakes quite a bit of research from a similar perspective.)

At some point, all the science will get done and the work will slide over to more engineering type work and we'll end up with a neat plane/gun/database/internet/drug/medical test/etc.
Though here they seem to be focusing on effectiveness rather than speed, so that's good. Just interesting to think about the fact that faster planes are only useful at this point if they're much, much faster.

The real problem was that there was no market for expensive planes that couldn't operate over land routes, or from many airports, because of the extreme noise and environmental concerns.
If supersonic passenger planes are ever going to be a reality again then these are the things that need to be addressed, and thankfully it seems NASA realises this.

On average Concorde made and operating profit of £30-50 Million a year for British Airways in the boom years where many passengers were travelling first class. British Airways reportedly received £1.75 Billion in revenue for Concorde services against an operating cost of around £1 Billion. Air France made a much smaller profit.
EX: 99$ tacked onto a 8-10K ticket it cheap. Bump that to say ~1k if they are picking you up directly and it's still in line with a Concord flight. http://onemileatatime.boardingarea.com/2015/01/21/gotham-air...
In other words, ground services were and are a key component of a premium travel offering, and can effectively shave a ton off the total travel time. Concorde flights predate the now-common practice of bundling chauffeured limousine rides with premium airfare, but you have to expect that the average Concorde passenger had adequate arrangements in place for their airport transfers.
I've only flown Concorde in the easterly direction, with none of the "chase the sun" appeal. But if you're accustomed to the drudgery of the regular JFK-LHR redeye, a breakfast in Concorde Room at 8 am, a very nice lunch at Mach 2.0, and wheels down in London before 5 pm is comparatively a very agreeable way to spend the first half of a work day.
Now, the only thing they need is that the queue doesn't run dry during those 2.5 hours. That means half the passengers can arrive 1 hour 15 minutes later, one in five about 2 hours later. If you are one of them, you help those coming early in the sense that they are less likely to have to waste time waiting in the check-in queues than in the slightly less annoying areas behind it (and of course, the early-comers help you to spend that hour in even less annoying circumstances)
And of course, assuming they have the capacity to process all passengers leaving every day, large airports could parallelize processing over multiple check-in queues, get processing time down to 30 minutes or so (using 6 check-in queues and a smart way to distribute load across them), and ask you to be there 60 minutes before departure.
I do not really see why they do not do that. There used to be a problem getting luggage on board the right plane, but with modern luggage processing, all bags end up on the same conveyer belt, anyways.
We could really use small jets out here in sparsely-populated Western USA. Eclipse Aviation got very close, then ran out of money. How much money would be required to start them up again?
We need new engines. My 1966 Cessna 172 required leaded AV gas, which is as rare -- and as damaging -- as the tears from a weeping unicorn.
Why invest in supersonic transport? We need low-end disruption, not high-end incremental improvements.
Frankly, not an arena where NASA is needed.
In Europe turbo-diesels are popular for retrofit because they happily consume Avtur ( kerosene ) which is cheap and plentiful. I've seen a few 172s with Thielert TD engines. There was also a project to install a TP100 turboprop but I'm not sure how that's progressing.
The fact that Cessna is still hawking a derivative of a 1947 airframe with an engine that isn't much fresher is more indicative of their attitude than any lack of advances in low-end aerodynamics. Look at the Stallion to see what they could be delivering, instead:

200 kts for 2,200 nm, seating for four people.
At the small-end we need disruption of the big-three ( Cessna, Piper, Beech ) manufacturers, with technology that exists but they don't bring to market. Projects such as the 177 and Starship show that they had the technology, they just didn't have the incentive to change.
Having known a bunch of aerospace people: this is in the works, it's just that we won't see it come out for a while because civil aero moves really slowly in an attempt to guarantee safety. Not "high probability of safety", not "we're pretty damn sure", guarantee. The levels of paranoia and conservative use of technology they get to are unbelievable. It's been roughly one military design generation, and only half a civilian generation, since the 1998-2000 crop of X-Planes. The military just got done deploying the delta-winged and fully-autonomous fruits of the 1998-2000 crop of X-Planes, which means that civilian aerospace is going to start working on it in another two or three years, will have designs in ten, and will start selling in fifteen.
"Goals include showcasing how airliners can burn half the fuel and generate 75 percent less pollution during each flight as compared to now, while also being much quieter than today’s jets – perhaps even when flying supersonic. " "Meanwhile, other experimental aircraft also are under consideration, including those with novel shapes that break the mold of the traditional tube and wing airplane, and others that are propelled by hybrid electric power. "
The supersonic boom should be one of the top priorities, also. Just look at this well-known video: https://www.youtube.com/watch?v=annkM6z1-FE , you can't have that happening over populated territory, meaning land.
Adding to that, just wanted to say that airplanes' sound pollution is a real and damaging thing. My parents live in a remote Eastern European village but, apparently, the skies over their house is a commercial airplane highway, as there were moments when I could count 6 or 7 of them up in the sky at the same time, including a big, white whale which looked like an A380. Anyway, it's not fun when it's 5 in the morning, you're surrounded by the four thick walls of your parents' house but you can still hear the airplane flying above your house at 30,000 feet.
Therefore, is it not possible to have supersonic jets for the likes of captains of industry, sports and other mega stars? Small, supersonic private jets? I can see a market for that. Lewis Hamilton would be first in the queue as would those Gulf 'sheikhs' that have small fleets of Boeing planes.
Economically I don't think there will ever be a market for the speed alone to command paying a much higher ticket price, but maybe technologies can be developed that will mean supersonic aircraft are as efficient (or more so) than subsonic aircraft.
Then a new model, the EA550 was built by the new company.
What killed Eclipse was gross mismanagement, lack of funding to cover that, and Cessna's Mustang.
Leaded 100LL avgas is certainly going away...

Also, to be clear: between Milner's two (fantastic) projects, he has committed $200 M, to be spent over roughly a decade. NASA's budget is about $19,000 M annually. For fast, efficient progress we need both—large amounts of government resources as well as private-sector funding of ideas that NASA and NSF are overlooking or not prioritizing for whatever reason.

(That's actually the original 1958 version. It's been amended occasionally since, but that will give you the gist.)
There are specific things I would alter about NASA's current course (including killing two projects worth a total of about $3 B per year) and I would amend the National Aeronautics and Space Act to alter its long-term trajectory regarding human activity in space, but much of NASA's job has been clear for decades.
