Gemini 11 orbited the earth at 800 kmh. http://www.friends-partners.org/partners/mwade/flights/gemini11.htm Apr 07 10, 7:25 PM

The speed needed to maintain an orbit around the earth is circular orbit: 6.9 to 7.8 km/s elliptic orbit: 6.5 to 8.2 km/s which equates to about 17, 500 miles per hour or 25 200 km/hour http://en.wikipedia.org/wiki/Orbital_speed Apr 07 10, 7:44 PM

Just to give a perspective, the International Space Station is in a low earth orbit, similar to what the space shuttle typically at (about 341 km above the equator). It has an orbital period of 91 minutes and a speed of 7,706.6 m/s. The Hubble Telescope is at a higher orbit (559 km) and is the limit to where human's travel due to the Van Allen radiation belt (except for lunar flights). The orbital period of the Hubble is 96.5 minutes with a velocity of 7,500 m/s. http://en.wikipedia.org/wiki/International_Space_Station http://en.wikipedia.org/wiki/Hubble_Space_Telescope Apr 09 10, 2:03 PM
