The Mars Insight mission is landing soon. NASA TV coverage starts at 2pm. Click this link to get you there, if you want to watch the coverage of the landing. The actual landing is at about 3pm EST.
I am a huge fan of Everyday Astronaut, so you may want to view his coverage on YouTube starting at 130pm EST.
This is a pretty rare occurrence, so I am getting this out quickly. Fan of NASA that I am, I was not aware today was the day.
I hope you enjoy the coverage as I will be.
