Flight
The Juno I rocket was launched January 31, 1958, putting Explorer 1 into orbit with a perigee of 358 kilometers (222 mi) and an apogee of 2,550 kilometers (1,580 mi) having a period of 114.8 minutes. At about 1:30 a.m. ET, after confirming that Explorer 1 was indeed in orbit, a news conference was held in the Great Hall at the National Academy of Sciences in Washington, DC to announce it to the world.
Mercury batteries powered the high-power transmitter for 31 days and the low-power transmitter for 105 days. Explorer 1 stopped transmission of data on May 23, 1958 when its batteries died, but remained in orbit for more than 12 years. It reentered the atmosphere over the Pacific Ocean on March 31, 1970 after more than 58,000 orbits.

Famous quotes containing the word flight:
“What a cunning mixture of sentiment, pity, tenderness, irony surrounds adolescence, what knowing watchfulness! Young birds on their first flight are hardly so hovered around.”
—Georges Bernanos (1888–1948)
“Here I am.... You get the parts of me you like and also the parts that make you uncomfortable. You have to understand that other people’s comfort is no longer my job. I am no longer a flight attendant.”
—Patricia Ireland (b. 1935)
“When we are high and airy hundreds say
That if we hold that flight they’ll leave the place,
While those same hundreds mock another day
Because we have made our art of common things ...”
