I'm not sure if this game is trying to look like No Man's Sky, but that's certainly what I thought when I first saw it. While the art style seems to be similar, the gameplay of Astroneer certainly does not. Here's the official description of the game from their Steam page...
Explore and exploit distant worlds in ASTRONEER – A game of aerospace industry and interplanetary exploration.The sudden development of technology for rapid space travel enables fast and inexpensive journeys to the stars. Exo Dynamics, the dominant conglomerate in the new field, has opened flights to daring citizens of Earth. Like the Yukon gold rush of old, waves of adventurers sign up to launch themselves into a new frontier, risking everything to seek their fortune in the far reaches of the galaxy. These are the Astroneers.
As an Astroneer, you must find a way to dig out a life on one of a multitude of harsh new worlds. Blast through the terrain to uncover precious artifacts and materials you can use to fuel your quest to become a wealthy baron in the stars. Along the way, discover oddities, raise questions, and uncover mysteries.
Perhaps not all is as it seems.
With the ability to explore "infinite worlds" and "shape the world around you" this game sounds like it was meant to be a toned down experience of No Man's Sky minus the fact that this one actually will have multiplayer. I'm not certain but I would also imagine it will be cheaper too. See the trailer below and watch out for it to enter early access sometime this year on Steam.
