Updated on June 29, 2015: The SpaceX Falcon 9 launch mishap of the unmanned rocket to resupply the International Space Station has impacted the projected launch date for the Jason-3 mission. While the incident review team looks into the cause of the mishap, NOAA and NASA are working with the European partners, France's Centre Nationale d'Etudes Spatiales (the French space agency) and EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites, to determine the next steps toward a new target launch date for Jason-3.

Social media users are invited to apply for credentials to cover the launch of the Jason-3 spacecraft. The event is designed for those who engage on social networks to learn more about the mission, witness its launch and share their experiences online.

Jason-3, a mission led by the National Oceanic and Atmospheric Administration (NOAA), is the latest in a series of U.S.-European satellite missions that have been measuring the height of the ocean surface since 1992. Sea surface height is a critical piece of evidence about Earth's natural cycles and how humans are affecting our planet. Knowing sea level height also improves hurricane forecasts, navigation and has implications for fishing and other offshore industries.

Jason-3 is scheduled to launch on Aug. 8, 2015, from Space Launch Complex 4 at Vandenberg Air Force Base in Lompoc, California.

A maximum of 70 social media users will be selected to attend the one-day event on Aug. 8 and will be given "behind-the-scenes" access, in an effort to align the experience of social media representatives with those of traditional media.

The credential application process for social media users for the Jason-3 launch opens June 24, 2015. All interested social media users must apply for credentials by 9 a.m. PDT (noon EDT) on July 3, 2015. All social media accreditation applications will be considered on a case-by-case basis.

For information and to apply, visit NASA Socials.

Approved event participants will have the opportunity to:

• Hear first-hand accounts by the Jason-3 science and engineering teams
• Get a behind-the-scenes tour of Vandenberg Air Force Base
• Meet fellow space, science and environmental science enthusiasts who are active on social media
• Meet members of NASA and NOAA's social media teams

Dates and times are subject to change based on mission requirements.

On the day of launch, event participants and their friends and families will be invited to a special public viewing area to watch Jason-3 lift off aboard a SpaceX Falcon 9 rocket.

Jason-3 is an international partnership led by the National Oceanic and Atmospheric Administration with participation from NASA, France's Centre Nationale d'Etudes Spatiales (the French space agency) and EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites. JPL built Jason-3's radiometer, GPS and laser reflector and is funding the launch and will help oversee the science team, which is responsible for ensuring the quality of the data. The California Institute of Technology in Pasadena manages JPL for NASA. NASA's Launch Services Program at the agency's Kennedy Space Center in Florida is responsible for launch management.
