Podcasting is officially out of this world - thanks to Space Shuttle Discovery astronaut and mission specialist Steve Robinson.
Robinson yesterday created the first podcast from space, sharing his experiences during the historic mission-critical spacewalk which took place over the weekend. He also discusses the crew's general experience of space flight.
The Discovery will come back to Earth today at 6.22am (EDT), 11.22am UK time. UPDATE: NASA has since delayed the return of the space craft for 24-hours.
NASA reveals that: "Commander Eileen Collins and the rest of the crew aboard Space Shuttle Discovery are still working through their landing checklist."
