NASA designed a follow-on autonomous or teleoperated prototype vehicle called the Mini-AERCam Robotic Space Vehicle. The free-flying robotic inspection vehicle was designed circa 2005 for remote viewing and inspection on human spaceflight missions. "The nanosatellite-class spherical Mini AERCam (Miniature Autonomous Extravehicular Robotic Camera) is just 7.5 inches (190 mm) in diameter and weighs approximately 10 pounds (4.5 kg)." The inspection vehicle moves by means of twelve cold-gas xenon thrusters for attitude and position control, distributed in four thruster pods on the vehicle. The Mini-AERCan never flew on a space mission.

Famous quotes containing the word follow:
“The Cairo conference ... is about a complicated web of education and employment, consumption and poverty, development and health care. It is also about whether governments will follow where women have so clearly led them, toward safe, simple and reliable choices in family planning. While Cairo crackles with conflict, in the homes of the world the orthodoxies have been duly heard, and roundly ignored.”
—Anna Quindlen (b. 1952)
“Because impudence is a vice, it does not follow that modesty is a virtue; it is built upon shame, a passion in our nature, and may be either good or bad according to the actions performed from that motive.”
—Bernard Mandeville (1670–1733)
