Two exoplanets thought to be similar to Earth apparently are, at least when it comes to climate, researc†Kepler-186f is the first identified Earth-sized planet outside the solar system orbiting a star in the habitable zone. This means it's the proper distance from its host star for liquid water to pool on the surface.
The study, which appears in the Astronomical Journal, used simulations to analyze and identify the exoplanet's spin axis dynamics.
Those dynamics determine how much a planet tilts on its axis and how that tilt angle evolves over time. Axial tilt contributes to seasons and climate because it affects how sunlight strikes the planet's surface.
Researchers suggest that Kepler-186f's axial tilt is very stable, much like the Earth, making it likely that it has regular seasons and a stable climate. Further, they think the same is true for Kepler-62f, a super-Earth-sized planet orbiting around a star about 1,200 light-years away from us.
Enceladus Life Finder (ELF) is a proposed astrobiology mission concept for a NASA spacecraft intended to assess the habitability of the internal aquatic ocean of Enceladus, which is Saturn's sixth-largest moon and seemingly similar in chemical makeup to comets. The spaceprobe would orbit Saturn and fly through Enceladus's geyser-like plumes multiple times. It would be powered by energy supplied from solar panels on the spacecraft.
The Enceladus Life Finder mission was first proposed in 2015 for Discovery Mission 13 funding, and then it was proposed in May 2017 to NASA's New Frontiers program Mission 4, but it was not selected.
Let me ask you something. Have you chosen Elon Musk as your personal lord and savior yet?
RUSSIAN billionaire Yuri Milner has set his sights on Saturn’s moon Enceladus.
Milner founded the $100 million Breakthrough Starshot project, an attempt to send small probes to Alpha Centauri. Now, he has announced plans to explore funding a mission to Enceladus.

The last time we went to the Moon was in 1972. We have really advanced with satellites and the collection of data but actual Space Exploration by humans themselves has been sorely lacking. Where's the big breakthroughs in this area?

Exactly. If we leave it all up to government resources then it would never actually get the attention that space exploration and colonization deserves.
I want to build fleets of ships and go out into the stars to colonize as much of the galaxy as possible. Can't do that without focused effort.
Meanwhile, in the decades it has operated it was never any closer to reusable rockets and other technologies that would reduce the cost of spaceflight.
