2030s-new moon landings(China, USA), India has manned flights in space, man lands on Mars-either USA or private
2040s-expect small moon stations by different counties(USA, China, EU/International), some space hotels, first habitable exoplanets in pictures,China lands on Mars
2050s-small research stations on Mars studying subsurface life
2069-first interstellar probe launched to Centauri System.Habitable planets too far away to be considered a valid target for quick mission(most likely within 10-20 light years).
That's as far as I can figure.
You will see China on the Moon, India in spacea and moon habitats for sure. Mars landing as well in next 20 years.
If exoplanets with biospheres exists we see first clues in 2020s, more details in 30s and first telescopes allowing us to take low resolution images could be in 40s.
