frequently asked questions
Something we've not covered here?
Yes, many NASA speakers deliver keynotes with Q&A, join panels, or run sessions on teamwork and risk for organisations. Formal workshops depend on the individual and how they like to engage. PepTalk will tell you who suits each format so the booking matches your event.
NASA speakers talk about space exploration, teamwork in extreme environments, innovation, risk and safety, the perspective gained from space, and scientific discovery. Many draw clear parallels with high-stakes business decisions. PepTalk matches the speaker to your audience so the session inspires and informs in equal measure.
A NASA speaker is an astronaut, scientist, or engineer affiliated with NASA who shares experience from space exploration and research. They bring stories and perspective few other people on earth can offer. PepTalk books NASA-affiliated speakers who make a standout, memorable moment for any event.
A NASA speaker draws on first-hand work in space programmes and research; a science communicator explains science broadly without necessarily having done the missions. Insider versus interpreter gives each a distinct voice. PepTalk can book either depending on what your event needs.
