NASA is set to make a big announcement about its mission to “touch the sun”—its first attempt at flying directly into the sun’s atmosphere, where the spacecraft will face unprecedented radiation levels and temperatures of up to 1,400 degrees Celsius.
Scientists working on the mission are set to hold a live event to provide further details about the plans for Solar Probe Plus on Wednesday 31 May at the University of Chicago. A live stream of the announcement will be shown on NASA TV from 11am EDT (4pm BST).
Solar Probe Plus is due to launch in July or August 2018, over 50 years since the concept was first proposed. It will make its close approach to the sun in December 2024, having carried out a flyby of Venus and a host of observations before it enters the solar atmosphere.
