For one, next-door neighbor Alpha Centauri is now known to have a planet! See "Earth-Size Planet Closest to Our Solar System: By The Numbers."
Closer to home (but not exactly homey), astronomers got their first good look at Makemake. No, that's not a type of sushi. It's one of five (so far) recognized "dwarf planets" in the Solar system. Makemake is about two-thirds the size of Pluto -- and (on average) even more remote. No atmosphere, either. For more, see "Dwarf planet Makemake examined for the first time."
But will astronauts get to Mars? That will require -- besides buckets of investment that don't seem imminent -- a degree of technical sophistication. Hence it's discouraging to encounter the latest dispatch from the Department of It's Not Rocket Science. To wit: NASA hasn't figured out that laptops can be stolen. And so we see that "NASA Suffers 'Large' Data Breach Affecting Employees, Contractors, and Others."
