Attitude Hold

by Kim Poor

(Not 'Altitude') Wearing an MMU (Manned Maneuvering Unit) enables astronauts to fly freely in space. In the "Attitude Hold" mode, the unit sets its gyroscopes and maintains a fixed position in space, firing its thrusters to compensate for any movement of the wearer.

This feature is handy for working on satellites, or for enjoying the view over the Gulf of Mexico, as seen here. This print is in the collections of several of the astronauts who have actually flown the MMU in space.

The city of Houston can be seen on the Texas coastline,
along with Brownsville (near the astronaut's feet), Corpus Christi and Austin.

"You should know that your "Attitude Hold" print occupies a place of great honor in our new offices. The relaxed EVA scene greets me everyday and I love it!"

--Joe Allen, astronaut STS-5, STS-51-A
