I agree completely.  The technological benefits of returning to space are boundless.    There is one intangible difficult to quantify—national pride in being THE country capable of providing much needed advances in technology and bringing forth the possibility of better living standards for the entire world.  In my opinion, advances in medicine would be worth the effort.   If we could eliminate 10 % of the waste and fraud in the Medicare and Medicade system we could finance NASA in a much more generous fashion.

I don't think any of NASA'a sensible and ultimately useful objectives in space require human presence. unless it's to provide material for press releases and "Discovery channel" documentaries. All of NASA's most impressive work - Hubble, Mars rovers, navigation satellites, apcae borne experiements - are carried out by unmanned craft via telemetry. Cheaper, safer, more productive. In terms of unmanned missions, NASA doesn't need to "return" to space. They are still up there.

@Battar: I agree with you that NASA doesn't need to "return" to space when they are already there.  However, I disagree that a human presence in space is unnecessary.  There is a lot of exploration that can be carried out by robotic probes, but human spaceflight is an important end in itself.

That being said, William Anders, the astronaut who took the iconic "Earthrise" photo, has said that we shouldn't travel to Mars until we're ready to do so as humans, rather than nationalistic Americans or Russians or Chinese or Indians.

I agree with that sentiment, although I'm not so sure about the possibly centuries-long wait it might impose.

Dave,

you say that "Human spaceflight is an important end in itself".

Why?

What problems does it solve, what scientific or engineering objectives does it meet?

If it's an emotional ideal, it's just not worth the multi-billion dollar investment. Just to put things in perspective, NASA could sent 3 robotic probes to Mars for the price of a single shuttle mission.

Latest Analysis
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
