Miniaturized bar codes were developed for space programs, but they are now widely used in manufacturing and industry. A metal alloy of nickel and titanium called nitinol is used in teeth braces. Nitinol was originally developed for space equipment such as antennae. The antennae are compacted for launch, before being expanded to full size in space. Nitinol is an ideal material for the job, since it has the ability to return to its original shape after bending. Back on Earth, nitinol allows braces to exert continuous pull on teeth.
NEAR left for the asteroid belt in 1996. It reached its target, the asteroid Eros, and on February 14, 2000, began to orbit it. On February 12, 2001, scientists changed NEAR’s flight plan and landed the probe on the asteroid—another first. have learned an enormous amount about the universe. The learning continues as the 21st century unfolds. Robotic probes are returning to worlds already seen first-hand and investigating others for the first time. New satellites replace craft that have served us well.

SOHO was designed to operate until 1998, but new funding has extended its working life to at least December 2009.

It was agreed that the probes, traveling in opposite directions, should carry messages in case any extraterrestrials came across them in the future.
