In April 1945, Hitler together with wife Eva Braun moved into the Fuhrerbunker in Berlin. Hitler held daily briefings with his generals and reports of the unstoppable Soviet into Berlin in his quarters. He issued frantic orders to defend Berlin with armies that were already wiped out or were making a hasty retreat westward to surrender to the Americans.

On April 22, Hitler let loose of hysteria; shrieking denunciation of the Army and the “universal treason, corruption, lies and failures” of those who deserted him. Hitler then admits his Reich was a failure and now there was nothing left to do but stay in Berlin and fight ‘til the end.

Before midnight of April 29, Adolf Hitler married Eva Braun in a brief civil ceremony and conducted a celebration in his private suit. By the afternoon of April 29, Soviet ground forces were about a mile away from the Fuhrerbunker. Inside the bunker the last news from the outside world told of the death of Mussolini.

At 2:30 in the morning of April 30, Hitler bid good byes to his staff members. At noon, Hitler attended to his last military situation conference and was told the Soviets were just a block away. At 2 pm, Hitler sat sown and had his last meal. Hitler and his wife went back in their private quarters while Bormann and Goebbels wait nearby.

A gunshot was heard at 3 pm and at 3:30; Bormann and Goebbels entered and found the body of Hitler on the sofa dripping with blood from a gunshot to his right temple while his wife Eva Braun had died from swallowing poison.

On April 6, 1973, Pioneer 11 was launched from Cape Canaveral. The 2.9-meter long unmanned spacecraft was the second mission (after its sister probe Pioneer 10) to investigate Jupiter and the outer solar system, and the first to explore the planet Saturn and its main rings. The spacecraft made a success to Saturn flyby and then followed an escape trajectory from the solar system.

Also called Pioneer G, Pioneer 11’s objectives were to study the interplanetary and planetary magnetic fields; solar wind properties; cosmic rays; transition region of the heliosphere; neutral hydrogen abundance; distribution, size, mass, flux, and velocity of dust particles; Jovian aurorae; Jovian radio waves; the atmospheres of planets and satellites; and the surfaces of Jupiter, Saturn, and some of their satellites. Pioneer 11 was developed out of NASA Ames Research Center as part of the Pioneer series of spacecraft.

In the year 1992 of this day, the last active US Navy Battleship — USS Missouri (BB-63) was decommissioned for the last time in Long Beach, California.

The BB-63, also known as “Mighty Mo” or “Big Mo” is an American battleship primarily used by the U.S Navy. The Big Mo was the third ship of the U.S Navy named in honor of the U.S state of Missouri. Missouri was noted as the last battleship to be built by the United States and the site of the Japanese surrender at the end of WWII. She was considered as one of the Iowa-class “fast battleship” designs planned in 1938 by the Preliminary Design Branch at the Bureau of Construction and Repair. The Mighty Mo was ordered on June 12 1940. On January 6, 1941, her keel was laid at the New York Navy Yard in the New York City borough of Brooklyn. She was launched on January 29 1944 and commissioned on June 11 of the same year. The ship was the fourth of the Iowa class and the final battleship commissioned by the US Navy. The ship was christened at her launching by Mary Margaret Truman, daughter of Harry S. Truman, a former senator from Missouri.

Missouri saw action at the Battle of Iwo Jima and the Battle of Okinawa, and shelled the Japanese home islands of Hokkaido and Honshu during World War II. Missouri fought in the Korean War, then was decommissioned into the United States Navy reserve fleets in 1955. She was recommissioned in the 1980s, and refitted with modern armaments. She also participated in the Gulf War in 1991.

On March 5, 1958 at 18:28 UTC, Explorer 2 (EXPLR2) was launched from Cape Canaveral Air Force Station (now Kennedy Space Center) by a Jupiter-C launch vehicle. Explorer 2 was to be a repeat of the Explorer 1 mission. However, due to a malfunction in the Jupiter-C launch vehicle, the fourth stage did not ignite. Subsequently, Explorer 2 did not reach orbit.

Explorer 2 was equipped with a Geiger counter for the purposes of detecting cosmic rays. The spacecraft was also equipped with a wide grid array and an acoustic detector for the purpose of micrometeorite detection.
