NASA has visited some awfully impressive places in the past 60 years, so it’s something of a wonder that the space agency hasn’t found its way to the sun by now. The New Horizons probe, which flew by Pluto in the summer of 2015, is now 3.5 billion miles (5.6 billion km) away; Voyager 1, launched in 1977, has left the solar system entirely, cruising through space at a remove of 11.7 billion miles (18.9 billion km) from Earth.

The sun, meantime, is within arms’ reach by cosmic standards, just 93 million miles (150 million km) away. And while it takes a lot of triangulating to get to Pluto, the sun is kind of hard to miss. Just point and shoot.

The problem of course, is that the sun is also — no surprise here — exceedingly hot. Temperatures in the corona — the blistering storm of plasma that stretches millions of miles into space and pops into view during a solar eclipse — approach 1 million degrees F (553,000° C). There’s a reason that the nearest any spacecraft has gotten to the solar inferno was 27 million miles (43 million km), a comparative close brush achieved by the Helios 2 spacecraft in 1976.

Now, however, NASA plans to get closer — a whole lot closer. At a press conference on May 31, NASA will officially announce the details and the launch date for the Solar Probe Plus spacecraft, a ship that will leave Earth next summer, sometime in a 20-day window from July 31 to Aug. 19, 2018.
