Buzz Aldrin didn't last very long as a Dancing with the Stars celebrity participant, but that doesn't mean he isn't happy with his accomplishments.

"I'm very proud to have had the opportunity to inspire a number of us who are trying to keep very active," said Aldrin during a Wednesday appearance on ABC's Good Morning America.

The former Apollo astronaut and his professional partner Ashley Costa became the second couple eliminated from Dancing with the Stars' tenth season during Tuesday night's live results show based on the combination of the judges' scores they received for their dance on Monday night's performance show and the home viewer votes cast afterwards.

"Ashley has been so tender throughout the entire opportunity that came my way -- and she naturally that way because she's the mother of two wonderful boys," said Aldrin during his GMA appearance.

Costa participated in Dancing with the Stars' first three seasons before leaving the show because she was pregnant with her first child.

She subsequently welcomed a second son and called her chance to return to the show "remarkable."

"I'm really grateful that I have this talent and I have family support to help me do the show and to help with Buzz," said Costa, who also appeared on GMA.

While Aldrin is no longer competing on Dancing with the Stars, he said he plans on maintaining a public presence to support something he feels passionately about.

"I'm really looking forward to making some major contributions to the administration's policy as will be carried out by the congress for the benefit of all those who have worked so hard for so many years to give our country the best space program in the world," he said on GMA.

"We need to maintain it that way."
