Mission Overview

The Sentinel-6 Michael Freilich spacecraft is developed and operated by the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), ESA, NASA and NOAA. The primary mission of Sentinel-6 is to provide ocean surface elevation data via a suite of instruments including synthetic aperture radar, and a GNSS radio occultation payload which will gather atmospheric temperature profile data as a secondary mission. Collected data will allow high precision tracking of sea level rise, and aide weather forecasting and climate modeling. Sentinel-6 Michael Freilich is the first of two Sentinel-6 satellites which will operate in the same orbit as, and eventually replace, previous Jason satellites. The primary contractor is Airbus.

Starlink-15 mission

Liftoff time: 10:56 am CST | Monday, November 23, 2020

Mission Overview

The 15th operational batch of Starlink satellites (16th overall) will lift off from SLC-40 at Cape Canaveral Space Force Station, Florida on a Falcon 9 rocket. In the weeks following deployment the Starlink satellites will use onboard ion thrusters to reach their operational altitude of 550 km. Falcon 9’s first stage will attempt to land on a droneship approximately 633 km downrange.

This mission is significant, as it is both the 100th Falcon 9 launch, as well as the first time a booster will have flown seven times. If the launch window for this launch holds, it will also be SpaceX’s fastest launch turnaround by about 14 hours. Finally, this will be the first time that SpaceX will launch four missions in one month.
