NEWQUAY, England, Jan 9 (Reuters) - Britain's attempt to become the first European nation to launch satellites into space ended in bitter disappointment early on Tuesday when Virgin Orbit said its rocket had suffered an anomaly that prevented it from reaching orbit. The "horizontal launch" mission had left from the coastal town of Newquay in southwest England, with Virgin's LauncherOne rocket carried under the wing of a modified Boeing 747 called "Cosmic Girl"... ...Virgin Orbit had initially said on Twitter that LauncherOne had reached earth orbit, a tweet it later deleted.
