A glove (Middle English from Old English glof) is a garment covering the whole hand. Gloves have separate sheaths or openings for each finger and the thumb; if there is an opening but no covering sheath for each finger they are called "fingerless gloves". Fingerless gloves with one large opening rather than individual openings for each finger are sometimes called gauntlets. Gloves which cover the entire hand or fist but do not have separate finger openings or sheaths are called mittens. Mittens are warmer than gloves made of the same material because fingers maintain their warmth better when they are in contact with each other. Reduced surface area reduces heat loss.
A hybrid of glove and mitten also exists, which contains open-ended sheaths for the four fingers (as in a fingerless glove, but not the thumb) and also an additional compartment encapsulating the four fingers as a mitten would. This compartment can be lifted off the fingers and folded back to allow the individual fingers ease of movement and access while the hand remains covered. The usual design is for the mitten cavity to be stitched onto the back of the fingerless glove only, allowing it to be flipped over (normally held back by Velcro or a button) to transform the garment from a mitten to a glove. These hybrids are called convertible mittens or glittens, a combination of "glove" and "mittens".
Chris Austin Hadfield, O.Ont, MSC, CD (born 29 August 1959) is a Canadian astronaut from the Canadian Space Agency (CSA) who was the first Canadian to walk in space. Hadfield has flown two space shuttle missions, STS-74 in 1995 and STS-100 in 2001. He has served as CAPCOM for both Space Shuttle and International Space Station (ISS) expeditions. He is currently training for a long duration stay on board the ISS, which will include command of Expedition 35 in 2012–13. He will be the first Canadian to command the ISS. He is enthusiastic about the prospects for a manned mission to Mars, and when asked if he would consider a one-way journey to Mars to be the first to visit, he said "I would be honoured to be given the opportunity."
Chris Hadfield was born in Sarnia, Ontario. His parents are Roger and Eleanor Hadfield who currently reside in Milton, Ontario. Hadfield was raised on a corn farm in southern Ontario and became interested in flying at a young age—from his own words in the interview to STRF.RU, he came to the idea of being astronaut when he was nine on the day of Apollo moon landing, which he had seen on TV then. Hadfield is married to his high-school girlfriend Helene Hadfield, and they have three adult children together.

His model work has appeared in major films, including Star Wars: Episode II - Attack of the Clones and The Matrix Reloaded. He is a prominent member of the skeptic community.

Born in New York City, Savage was raised in Sleepy Hollow in Westchester County New York. He graduated from Sleepy Hollow High School in 1985. His father, Whitney Lee Savage (1928-1998), was a painter, filmmaker and animator known for his work on Sesame Street, and has a permanent exhibit in the Avampato Discovery Museum. His mother is a psychotherapist. His sister Kate Savage is also an artist. As a teenager in Sleepy Hollow, he routinely visited the local bike shop to have flat tires fixed. The shop showed him how to do the repairs himself. From this experience, Savage said, "I realized you could take a bike apart and put it back together and it wasn't that hard...I've been building and putting bicycles together since then."
