I have written about my "dabbling" in the aerospace field in a number of threads on ATS over the years (decades!).
Basically, I worked with a group of dreamers who, back in the early 1980's first conceived of a proposal for a manned Orbital Transfer Vehicle (OTV)
using xenon ion thrusters as it's propulsion. But, since we were not a government agency, nor an established defense contractor, we were unable to
acquire the funding necessary to pursue the project.
We then turned to the development of an "experiment bus" intended to facilitate other R&D firms access to in orbit experimental environments via the
Space Shuttle "Get-Away-Special" program. But the loss of the Challenger ended that program, and, for two or three years, also ended
Any
non-NASA or non-military, participation in the space program altogether.
We kicked around a few ideas for microgravity research systems, until, in early 1990, we decided that it was time to break the government/military
hold on access to space.
We set about designing a rocket and launch system based on a high-powered "hobby" rocket that we believed could reach the Karman Line (approximately
62 miles in altitude) using a modification of a technique first employed by Dr. James Van Allen (who discovered Earth's radiation belts, now named
after him) called a
"rockoon".
My primary contribution was the design and construction of a launch tube system that would keep the solid fuel of the rocket above freezing while
being lofted to its 140,000FT planned launch altitude. Temperature at that height can be as low as -50°F. And we had traumatic memories of what can
happen when solid fuel engines are allowed to freeze.
What we didn't really appreciate at the time, was that the US government did not have a clue as to how to
regulate private, commercial, space
operations. Such a thing did not exist before then.
So, in addition to developing are nascent space system, some of our more administratively minded team members set to work with the FAA to develop
regulatory guidelines for the "first mile" of future launch operations.
When Branson and Musk rolled up, their programs were benefitting from the groundwork we helped to establish.
Unfortunately, my health took a serious turn about this time, and I was forced to give up long treks into our high-desert launch site, miles from
access to medical care, should it be required. And so I "retired" from the project.
An iteration of that team still exists, as a private company now.
PM me for their info.

Sorry, got carried away for a bit and forgot to answer your question!
I think we are
close to having the technology that would allow us to land on Mars. The recent findings regarding the Martian aquifer certainly
provide ample motivation to pursue that mission.
But the simple fact is that, as a society, and even as a
species, we have become too risk averse to attempt such a feat without much more
reassuring experience.
Some ask why we haven't gone back to the Moon. And there are a plethora of solid, rational, reasons why it just hasn't been a priority.
But the real reason IMO, is because we have "grown" too afraid of trying to do something "big", like a moonshot, and failing.
Children dare what adults fear to contemplate.
