  • A US-European satellite designed to extend a decades-long measurement of global sea surface heights was launched into Earth orbit from California on Saturday.
  • Named for a former NASA official who had a key role in developing space-based oceanography, the satellite’s main instrument is an extremely accurate radar altimeter that will bounce energy off the sea surface as it sweeps over Earth’s oceans.
  • The measurements are also important for understanding overall sea level rise due to global warming that scientists warn is a risk to the world’s coastlines and billions of people.
