If you are wondering why they have not heard if TESS was launched successfully on Monday; that was because rocket issues pushed back the launch to today.
The Falcon 9 carrying NASA’s TESS satellite is now scheduled for 6:32 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida today.
Standing down today to conduct additional GNC analysis, and teams are now working towards a targeted launch of @NASA_TESS on Wednesday, April 18.
