NASA spacecraft reunites with Earth after 17-year trip around the sun
Story by Daniel Wu
For nearly 17 years, NASAs Solar Terrestrial Relations Observatory-A spacecraft drifted through space on a lonely mission. It traveled around the sun far ahead of Earth, conducting groundbreaking research on the solar systems star.
Like many NASA spacecraft, STEREO-A outlived its mission life span of two years. Instead, it traveled further and further away from Earth on a journey that became fraught with uncertainty as it passed behind the sun in 2015, temporarily severing contact with NASA. The same year, the agency lost contact with STEREO-As sibling vessel, STEREO-B, which was traveling a similar path.
But STEREO-A kept going. And its orbital trajectory around the sun meant that it had a chance to do what very few other NASA spacecraft could: eventually make its way back toward home.
That came to fruition earlier this month, when STEREO-A passed between the sun and the Earth for the first time since its launch in 2006, NASA announced. The flyby marked a milestone for the spacecraft and the team that has monitored its progress and a chance for STEREO-A to prove its relevance almost two decades later. As it continues to pass by Earth, STEREO-A will be used to perform new research on the sun, aided by newer NASA satellites that have been developed since its launch.
This is a point in time for this mission to shine again, Lika Guhathakurta, STEREOs program scientist, told The Washington Post.

I wonder if there's any chance they can manage to get STEREO-B back to talking to us or if it's lost forever?
