Following a four-month mission at the International Space Station highlighted by a video chat with the pontiff himself, these astronauts have now returned to Earth and made sure to pay the Holy Father a visit in person.
They also brought their families along for the eventful encounter.
One of the little ones set the tone, warming the hearts of Pope Francis and her parents by presenting the pontiff with this photo of space bearing a Bible verse.
The gifts didn't end there. To show their appreciation, the astronauts presented Pope Francis with an authentic, customized suit.
And as for their visit, it wouldn't have been complete without the Holy Father's autograph on their Bibles.
During the encounter, the astronauts found many parallels between their profession and Pope Francis' vision for themes like the peripheries and care for the common home.
