It was a NASA tragedy. NASA’s Shuttle program was begun in the 1970s, to create reusable craft for transporting cargo into space. Previous space craft could only be used once, then were discarded.

Black holes emit x-ray radiation and get smaller and smaller until they disappear, or “evaporate”.
* Most black holes are formed from the death of large stars (larger than the sun) that run out of fuel and cannot sustain its nuclear reaction. The star loses the force pushing itself outward and is overcome by the force [...]
Biggest Space Explosion Creates Giant Bubbles
The largest explosion ever seen in space reveals black holes to be more influential than expected, perhaps sometimes stifling star formation in a galaxy while gobbling up trillions upon trillions of tons of gas.
The eruption has been ongoing for some 100 million years, [...]
Yuri Gagarin was born near Moscow, Russia on March 9, 1934. He died on March 27, 1968. Yuri joined the Soviet Air Force in 1955. By 1959, he was training to become a cosmonaut.
