Watch a video replay of NASA’s exoplanet announcement

Carol Raymond helps lead the Dawn science team at NASA’s Jet Propulsion Laboratory in Pasadena, California, where she oversees research investigating comets and asteroids, including the two objects visited during Dawn’s decade-long mission: Vesta and Ceres.

Concerns about the health of the Juno spacecraft’s main engine have compelled NASA managers to keep the research probe in its current arcing, high-altitude orbit around Jupiter, a decision that will delay the full science return from the $1.1 billion mission but should still allow it to meet all predetermined objectives.

Officials from NASA, research institutions and companies involved in the development and launch of the Transiting Exoplanet Survey Satellite briefed reporters in the mission Sunday, the day before its scheduled liftoff from Cape Canaveral.
