Guion Bluford: engineering work aboard STS-8 and beyond

A mission-focused profile of Bluford’s four Shuttle flights and technical responsibilities.

By · Published · Updated · 2 min read

The short answer

Guion Bluford was a NASA mission specialist whose first flight, STS-8, launched aboard Challenger on 30 August 1983.

The mission record behind the biography

NASA’s biographical data lists Bluford’s four flights: STS-8, STS-61A, STS-39 and STS-53. It describes ground assignments involving Shuttle systems, payload safety and flight-software verification.

On STS-8, the crew deployed India’s INSAT-1B and conducted other technical and scientific activities. These are crew-level accomplishments; the biography should not be read as assigning every task solely to Bluford.

What “mission specialist” adds to the story

A flight biography needs to distinguish the spacecraft, the mission and the person’s role. Naming an orbiter identifies the vehicle; naming a mission identifies a particular flight; naming the role explains how the astronaut contributed to the operation.

Ground assignments matter too. Software checking and payload review take place before a launch and can be less visible than flight photographs, even though they form part of the operational preparation.

A simple mission-reading exercise

For an illustrative classroom activity, make three columns labelled vehicle, flight and task. Put Challenger under vehicle and STS-8 under flight; then place satellite deployment under the crew’s recorded activities. Do not turn the columns into a claim that the spacecraft and mission names mean the same thing.

Repeat the exercise with a later flight from the biography. The point is to connect a person’s career to documented operations, rather than infer details from a familiar name or a launch date.

Why specific attribution helps

A good technical profile can recognise individual service while making teamwork explicit. It can also distinguish selection or qualification as an astronaut from the date of an actual spaceflight.

Use the original NASA data sheet for further mission detail. The exercise above is an original study aid, and the dated historical record is not evidence of a present-day appointment or a newly announced flight.
