The launch vehicle Delta IV Heavy in Florida with Parker probe Solar Probe, which will study the solar corona, has been postponed until Sunday, reports Spaceflight Now.

The launch is owned by United Launch Alliance (ULA) rocket was previously scheduled for 10:53 Moscow time from the cosmodrome on Cape Canaveral (FL).

«Group launch, ULA is preparing for another attempt to send the Delta IV Heavy (probe) Parker Solar Probe on Sunday. The launch window opens tomorrow at 03.31 time EDT (10.31 MSK)», — informs a portal.

The creators of the probe hope that he will be able to approach the star at a distance of 6.1 million kilometers above its surface. So close to the Sun had not approached no man-made probe.

Parker Solar Probe includes a range of tools, located under the massive heat shield that must protect the probe from «sun burn», including the camera, a device for measuring magnetic and electric fields in the solar atmosphere, as well as two tools for measuring and monitoring particle «solar wind».

Earlier NASA reported that the first approximation of the camera with the Sun in November, the first received photos will be downlinked to the Ground in December.
