According to this link:http://nasawatch.com/archives/2015/12/nasa-will-not-b.html,InSight, which was supposed to launch on an Atlas V in March 2016 from Vandenberg has been delayed to an undetermined date in 2018.
Via Satellite: Do you have other satellites planned for the future?Yang: As already mentioned, we will launch two more satellites, Koreasat 7 and 5A in 2016 and 2017 respectively.
According to this ISS researcher's blog, the next SpaceX Dragon delivery is delayed to no earlier than March 2. http://www.grimm-space-research.com/page4/Blog/Blog.html
In the night to Saturday, I received a forwarded email from NASA in which all experimenters scheduled for SpaceX 8 were informed that there is a new scheduling of launches going on and that they hopefully will be able to inform us next week (meaning this week) about anything more specific. However, in this email it was unambiguously stated that we 'can assume SpX 8 will launch no earlier than 2 March 2016'.
From launchphotography.com, SpaceX CRS-8's launch time is now 12:23 AM (04:23 UTC) on March 20, 2016.Also, are we still in 2015?
