TEDxSanJoseCA - Jeff Greason - Rocket Scientist: Making Space Pay and Having Fun Doing It

Jeff Greason has devoted his life's work to creating and managing innovative technical project teams at XCOR Aerospace, Rotary Rocket Company (RRC), and Intel Corporation. Time magazine named Jeff as one of their "Inventors of the Year" for his team's work on the EZ- Rocket in 2002. He is the president and co-founder of XCOR; leading an engineering team that has developed 11 different long life, highly reusable, liquid-fueled rocket engines using nitrous oxide, liquid oxygen, and hydrogen peroxide oxidizers, with kerosene, alcohol, ethane, and other nontoxic propellants. Under Jeff's leadership the company has also developed low cost liquid propellant piston pumps and two generations of piloted reusable rocket aircraft. The EZ-Rocket was flown 26 times, and the X-Racer flew 40 times, without a mishap. Jeff is also the co-inventor of XCOR's Nonburnite technology.

La tripulación de la Estación Espacial Internacional habla de la vida a bordo euronews, i talk

Hace 50 años Yuri Gagarin realizó el primer viaje del hombre al espacio. Muchas cosas han cambiado desde entonces allí arriba. Actualmente seis astronautas viven y trabajan en la Estación Espacial Internacional. Los espectadores de Euronews les han hecho varias preguntas sobre su labor.

Sus investigaciones no sólo facilitarán, por ejemplo, el viaje a Marte. También tendrán sus efectos sobre la Tierra. Están estudiando varias enfermedades cardiovasculares, el funcionamiento del cerebro y un tratamiento contra la osteoporosis.

Desde el espacio, cuentan cómo es la vida con gravedad cero y cómo se ve la Tierra desde tan lejos.

Europe - ISS - Space mission - Space research

The focus of this week's i-talk, Euronews' new programme presented by "Mr. Europe" Alex Taylor, is the 50th anniversary of Yuri Gagarin's trip to space -- the first ever manned space-travel.

Answering the viewers' questions are the International Space Station's current occupants: commander Dimitri Kondratyev, flight engineer Katie Colman, Paulo Nespoli, Andrei Samokutyaev, Ron Garan and Andrey Borisenko.

Find out how their experience is contributing to medical research, whether space tourism is just round the corner, and what happens to the human body when you spend time in space.

This week, in i-talk, with Alex Taylor.
