Quite a lot has been going on:

Sentinel-6 Michael Freilich Satellite Prepared for Launch

A little more than two minutes after the Falcon 9 rocket lifts off, the main engine will cut off. Shortly after, the rocket’s first and second stages will separate, followed by second-stage engine start. The reusable Falcon 9 first stage will then begin its automated boost-back burn to the launch site for a propulsive landing.

The first cutoff of the second stage engine will take place approximately eight minutes after liftoff. It will fire a second time 45 minutes later, at which point the launch vehicle and the spacecraft will be in a temporary “parking” orbit. Several minutes later, the launch vehicle and the spacecraft will separate. The satellite will begin solar panel deployment about one hour and seven minutes post-launch and is expected to make first contact about 25 minutes after that.

NASA Satellite To Measure Global Sea Level Rise

A satellite scheduled to launch from California later this month will measure sea level rise and provide other crucial data to scientists who study how global warming is affecting the Earth’s oceans.

Melting ice has already caused sea levels to rise by about 8 inches since 1880, and the trend is accelerating. The Earth’s oceans have soaked up the vast majority of the extra heat, and about one quarter of the extra carbon dioxide, that humans have generated by burning fossil fuels.

SpaceX will boost a new NASA satellite and land with a boom this weekend

The next SpaceX Falcon 9 launch is slated to carry a new NASA and European Space Agency satellite to orbit as soon as Saturday.

The payload will be the Sentinel-6 Michael Freilich satellite, which is the latest in a series of satellites that have provided critical data about sea level rise and climate change for almost three decades. It’s named for the former director of NASA’s Earth Science Division, Michael Freilich, who is considered a pioneer in conducting oceanography work from orbit.

Liftoff is currently set for Saturday at 9:17 a.m. PT, and you can watch via the live feed embedded below.

NASA is targeting 12:17 p.m. EST (9:17 a.m. PST) Saturday, Nov. 21, for the launch of the Sentinel-6 Michael Freilich satellite, the first of two identical satellites to head into Earth orbit five years apart to continue sea level observations for at least the next decade.

Live launch coverage will begin at 11:45 a.m. EST (8:45 a.m. PST), on NASA Television and the agency’s website, with prelaunch and science briefings the day before on Nov. 20.
