Abby and Brittany Hensel Abby and Brittany Hensel Abigail Loraine Hensel and Brittany Lee Hensel (born March 7, 1990) are American dicephalic parapagus twins; also known as conjoined twins. They are highly symmetric for conjoined twins, giving the appearance of having a single body without marked variation from normal proportions. Each has a separate heart, stomach, spine, pair of lungs, and spinal cord. Each twin controls one arm and one leg. As infants, learning to crawl, walk and clap required them to cooperate. They can eat and write separately and simultaneously. Activities such as running, swimming, hair brushing and driving a car require coordinated
TWINS TWINS Two Wide-Angle Imaging Neutral-Atom Spectrometers (TWINS) are a pair of NASA instruments aboard two United States National Reconnaissance Office satellites in Molniya orbits. TWINS was designed to provide stereo images of the Earth's ring current. The first instrument, TWINS-1, was launched aboard USA-184 on 28 June 2006. TWINS-2 followed aboard USA-200 on March 13, 2008. Each instrument consists of an energetic neutral atom imager and a Lyman alpha detector. The ENA imager provides indirect remote sensing of the ring current ions, and the Lyman alpha detector gives a measure of the neutral hydrogen cloud about the Earth, known as
