Jim Aubert is a Sandia National Laboratory scientist developing a new adhesive that loosens when heated. His epoxy adhesive is temperature dependent, so it sticks at room temperature, but at elevated temperatures it melts and allows separation. "Our approach relies on reversible chemistry that breaks apart the adhesive at elevated temperatures," says Aubert. For more information, go to www.sandia.gov.
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
