WASHINGTON — Journalists are invited to participate in a NASA Social from 9:30 a.m. to noon EST Wednesday, Feb. 20, in the James Webb Auditorium of NASA Headquarters at 300 E St. SW in Washington.

During this event, 150 social media followers and their guests will speak with three of the six crew members currently aboard the International Space Station orbiting about 240 miles above Earth. The participants also will hear from agency scientists and engineers about ground-breaking research taking place daily on the orbiting laboratory.

NASA Socials are in-person meetings for people who engage with the agency through Twitter, Facebook, Google+ and other social networks.

Participants in this NASA Social will learn about the discoveries enabled by the space station’s unique microgravity environment that benefit humanity and increase our understanding of how humans can safely work and live in space for long periods.

Astronauts and officials scheduled to meet with the NASA Social participants are:

— Astronauts Kevin Ford and Tom Marshburn of NASA and Chris Hadfield of the Canadian Space Agency will participate from the space station

— NASA astronaut Don Pettit, a former space station resident
