	Spacecrafts launched in 1999 (Site not responding. Last check: 2007-11-01)
		For a while the Ikar was in a similar orbit to the Globalstars, but it made a depletion deorbit burn on 16 March and reentered.
		The satellite was placed in orbit with the first launch of Russia's Dnepr rocket, which isw a converted R-36M2 (15A18M) ballistic missile (NATO codename SS-18 mod 4), developed by the Yuzhnoye (Pivdenne) organization in the Ukraine and marketed by MK Kosmotras.
		The planned orbit after the first OAM burn was 220 km x 689 km x 98.1°; the second OAM burn would have placed Ikonos in a 680 km x 690 km x 98.1° circular orbit.

	Cape Canaveral
		COURIER I-B active communications satellite successfully placed into orbit by Thor-Able-Star launch vehicle from Cape Canaveral.
		After completing one orbit it received and recorded a transcribed message to the United Nations by President Eisenhower transmitted from Fort Monmouth, N.J., and retransmitted it to another earth station in Puerto Rico.
		This marked the 100th launch of the Douglas Thor, military and scientific combined, and a Thor record of 60 percent of the U.S. satellites boosted into orbit.

		This added weight would require multiple launches of hardware, propellants, and supplies into low Earth orbit and the assembly of the entire Mars Transportation Vehicle in Earth orbit.
		Once assembled, the Mars Transfer Vehicle would fire its rockets and propel the entire system onto a heliocentric orbit that would bring our astronauts to Mars within 100 to 259 days, nominally speaking.
		The payload of an Atlas rocket, for instance, could be multiplied by three or four times using a nuclear upper stage.
