Lost in Space 05

The surviving colonists build a light tower to try to signal the Resolute.

Maureen, noticing strange weather phenomena, conducts an experiment using a weather balloon. She discovers the sun is paired with a deadly black hole, and that the disturbances will only get worse until the planet gets entirely unhabitable.

A decent episode that slowly moves multiple plots along.

That is, until a confrontation with a CGI creature and the robot turns upĀ  in the nick of time for a neat CGI battle. Dr Smith is beginning to look like an ineffective villain, wandering around and poking into everyone’s business.
