 On This Date In History


On April 9, 1865, in Appomattox Court House, Virginia, Robert E. Lee surrenders his 28,000 Confederate troops to Union General Ulysses S. Grant, effectively ending the American Civil War. Forced to abandon the Confederate capital of Richmond, blocked from joining the surviving Confederate force in North Carolina, and harassed constantly by Union cavalry, Lee had no other option.
In retreating from the Union army’s Appomattox Campaign, the Army of Northern Virginia had stumbled through the Virginia countryside stripped of food and supplies. At one point, Union cavalry forces under General Philip Sheridan had actually outrun Lee’s army, blocking their retreat and taking 6,000 prisoners at Sayler’s Creek. Desertions were mounting daily, and by April 8 the Confederates were surrounded with no possibility of escape. On April 9, Lee sent a message to Grant announcing his willingness to surrender. The two generals met in the parlor of the Wilmer McLean home at one o’clock in the afternoon.
Lee and Grant, both holding the highest rank in their respective armies, had known each other slightly during the Mexican War and exchanged awkward personal inquiries. Characteristically, Grant arrived in his muddy field uniform while Lee had turned out in full dress attire, complete with sash and sword. Lee asked for the terms, and Grant hurriedly wrote them out. All officers and men were to be pardoned, and they would be sent home with their private property, most important, the horses, which could be used for a late spring planting. Officers would keep their side arms, and Lee’s starving men would be given Union rations.
General Grant told his officers, “The war is over. The Rebels are our countrymen again.” Although scattered resistance continued for several weeks, for all practical purposes the Civil War had come to an end.

On April 9, 1959, the National Aeronautics and Space Administration (NASA) introduces America’s first astronauts to the press: Scott Carpenter, L. Gordon Cooper Jr., John H. Glenn Jr., Virgil “Gus” Grissom, Walter Schirra Jr., Alan Shepard Jr. and Donald Slayton. The seven men, all military test pilots, were carefully selected from a group of 32 candidates to take part in Project Mercury, America’s first manned space program. NASA planned to begin manned orbital flights in 1961.
On October 4, 1957, the USSR scored the first victory of the “space race” when it successfully launched the world’s first artificial satellite, Sputnik, into Earth’s orbit. In response, the United States consolidated its various military and civilian space efforts into NASA, which dedicated itself to beating the Soviets to manned space flight. In January 1959, NASA began the astronaut selection procedure, screening the records of 508 military test pilots and choosing 110 candidates. From among these men, the selection committee was to choose six based on interviews, but seven candidates were so strong they ended up settling on that number.
After they were announced, the “Mercury Seven” became overnight celebrities. The Mercury Project suffered some early setbacks, however, and on April 12, 1961, Soviet cosmonaut Yuri Gagarin orbited Earth in the world’s first manned space flight. Less than one month later, on May 5, astronaut Alan Shepard was successfully launched into space on a suborbital flight. On February 20, 1962, in a major step for the U.S. space program, John Glenn became the first American to orbit Earth. NASA continued to trail the Soviets in space achievements until the late 1960s, when NASA’s Apollo program put the first men on the moon and safely returned them to Earth.

 On This Date In History


On February 20, 1962, from Cape Canaveral, Florida, John Herschel Glenn Jr. is successfully launched into space aboard the Friendship 7 spacecraft on the first orbital flight by an American astronaut.
Glenn, a lieutenant colonel in the U.S. Marine Corps, was among the seven men chosen by the National Aeronautics and Space Administration (NASA) in 1959 to become America’s first astronauts. A decorated pilot, he flew nearly 150 combat missions during World War II and the Korean War. In 1957, he made the first nonstop supersonic flight across the United States, flying from Los Angeles to New York in three hours and 23 minutes.
Glenn was preceded in space by two Americans, Alan B. Shepard Jr. and Virgil I. “Gus” Grissom, and two Soviets, Yuri A. Gagarin and Gherman S. Titov. In April 1961, Gagarin was the first man in space, and his spacecraft Vostok 1 made a full orbit before returning to Earth. Less than one month later, Shepard was launched into space aboard Freedom 7 on a suborbital flight. In July, Grissom made another brief suborbital flight aboard Liberty Bell 7. In August, with the Americans still having failed to make an orbital flight, the Russians sprinted further ahead in the space race when Titov spent more than 25 hours in space aboard Vostok 2, making 17 orbits. As a technological power, the United States was looking very much second-rate compared with its Cold War adversary. If the Americans wanted to dispel this notion, they needed a multi-orbital flight before another Soviet space advance arrived.
It was with this responsibility in mind that John Glenn lifted off from the launch pad at Cape Canaveral at 9:47 a.m. on February 20, 1962. Some 100,000 spectators watched on the ground nearby and millions more saw it on television. After separating from its launching rocket, the bell-shaped Friendship 7 capsule entered into an orbit around Earth at a speed of about 17,500 miles per hour. Smoothing into orbit, Glenn radioed back, “Capsule is turning around. Oh, that view is tremendous.”
During Friendship 7‘s first orbit, Glenn noticed what he described as small, glowing fireflies drifting by the capsule’s tiny window. It was some time later that NASA mission control determined that the sparks were crystallized water vapor released by the capsule’s air-conditioning system. Before the end of the first orbit, a more serious problem occurred when Friendship 7‘s automatic control system began to malfunction, sending the capsule into erratic movements. At the end of the orbit, Glenn switched to manual control and regained command of the craft.
Toward the end of Glenn’s third and last orbit, mission control received a mechanical signal from the spacecraft indicating that the heat shield on the base of the capsule was possibly loose. Traveling at its immense speed, the capsule would be incinerated if the shield failed to absorb and dissipate the extremely high reentry temperatures. It was decided that the craft’s retrorockets, usually jettisoned before reentry, would be left on in order to better secure the heat shield. Less than a minute later, Friendship 7 slammed into Earth’s atmosphere.
During Glenn’s fiery descent back to Earth, the straps holding the retrorockets gave way and flapped violently by his window as a shroud of ions caused by excessive friction enveloped the spacecraft, causing Glenn to lose radio contact with mission control. As mission control anxiously waited for the resumption of radio transmissions that would indicate Glenn’s survival, he watched flaming chunks of retrorocket fly by his window. After four minutes of radio silence, Glenn’s voice crackled through loudspeakers at mission control, and Friendship 7 splashed down safely in the Atlantic Ocean. He was picked up by the USS destroyer Noa, and his first words upon stepping out of the capsule and onto the deck of the Noa were, “It was hot in there.” He had spent nearly five hours in space.
Glenn was hailed as a national hero, and on February 23 President John F. Kennedy visited him at Cape Canaveral. He later addressed Congress and was given a ticker-tape parade in New York City.
Out of a reluctance to risk the life of an astronaut as popular as Glenn, NASA essentially grounded the “Clean Marine” in the years after his historic flight. Frustrated with this uncharacteristic lack of activity, Glenn turned to politics and in 1964 announced his candidacy for the U.S. Senate from his home state of Ohio and formally left NASA. Later that year, however, he withdrew his Senate bid after seriously injuring his inner ear in a fall. In 1970, following a stint as a Royal Crown Cola executive, he ran for the Senate again but lost the Democratic nomination to Howard Metzenbaum. Four years later, he defeated Metzenbaum, won the general election, and went on to win reelection three times. In 1984, he unsuccessfully sought the Democratic nomination for president.
In early 1998, NASA announced it had approved Glenn to serve as a payload specialist on the space shuttle Discovery. On October 29, 1998, nearly four decades after his famous orbital flight, the 77-year-old Glenn became the oldest human ever to travel in space. During the nine-day mission, he served as part of a NASA study on health problems associated with aging. In 1999, he retired from his U.S. Senate seat after four consecutive terms in office, a record for the state of Ohio. He died on December 8, 2016.

 

 



On February 20, 1864, at the Battle of Olustee, the largest conflict fought in Florida during the Civil War, a Confederate force under General Joseph Finegan decisively defeats an army commanded by General Truman Seymour. The victory kept the Confederates in control of Florida’s interior for the rest of the war.
Olustee was the climax to a Union invasion of Florida a few weeks before. General Quincy Gilmore, commander of the Union’s Department of the South, dispatched Seymour to Jacksonville on February 7. Seymour’s troops secured the town and began to send cavalry raiders inland to Lake City and Gainesville. Just behind the troops came John Hay, private secretary to President Abraham Lincoln. Hay began issuing loyalty oaths to residents in an effort to form a new, Republican state government in time to send delegates to the 1864 party convention. Under the president’s plan of reconstruction, a new state government could be formed when 10 percent of the state’s prewar voting population had taken a loyalty oath.
Seymour began moving towards Lake City, west of Jacksonville, to destroy a railroad bridge and secure northern Florida. Finegan possessed only 500 men at Lake City, but reinforcements were arriving. By the time the two sides began to skirmish near the Olustee railroad station, each side had about 5,000 troops. Throughout the day on February 20, a pitched battle raged. The Confederates were close to breaking the Yankee lines when they ran low on ammunition. When more cartridges arrived, the attack continued. By late afternoon, Seymour realized the fight was lost and he began to retreat.
The Yankees suffered around 1,800 killed, wounded, or captured, while the Confederates lost about 900 men. The battle did disrupt the flow of supplies from Florida to other Confederate armies, but it failed to bring about a new state government. Most of Florida remained in Confederate hands until the end of the war.

On February 20, 1942, Lt. Edward O’Hare takes off from the aircraft carrier Lexington in a raid against the Japanese position at Rabaul, and minutes later becomes America’s first WWII flying ace.
In mid-February 1942, the Lexington sailed into the Coral Sea. Rabaul, a town at the very tip of New Britain, one of the islands that comprised the Bismarck Archipelago, had been invaded in January by the Japanese and transformed into a stronghold, in fact, one huge airbase. The Japanese were now in prime striking position for the Solomon Islands, next on the agenda for expanding their ever-growing Pacific empire. The Lexington‘s mission was to destabilize the Japanese position on Rabaul with a bombing raid.
Aboard the Lexington was U.S. Navy fighter pilot Lt. Edward O’Hare, attached to Fighting Squadron 3 when the United States entered the war. As the Lexington left Bougainville, the largest of the Solomon Islands in the South Pacific (and still free from Japanese control), for Rabaul, ship radar picked up Japanese bombers headed straight for the carrier. O’Hare and his team went into action, piloting F4F Wildcats. In a mere four minutes, O’Hare shot down five Japanese G4M1 Betty bombers, bringing a swift end to the Japanese attack and earning O’Hare the designation “ace” (given to any pilot who had five or more downed enemy planes to his credit).
Although the Lexington blew back the Japanese bombers, the element of surprise was gone, and the attempt to raid Rabaul was aborted for the time being. O’Hare was awarded the Medal of Honor for his bravery, and excellent aim. In 1949, Chicago officials named the O'Hare International Airport after him.

Astronauts dropped a tool bag during an ISS spacewalk, and you can see it with binoculars.

A tool bag that gave astronauts the slip during a spacewalk at the International Space Station is surprisingly bright and can be seen with binoculars.
Some astronomy targets are less celestial in nature than others.
Joining stars, planets, nebulas, and galaxies as a target for skywatchers is now a surprisingly bright tool bag floating through the space around Earth. The bag of tools gave NASA astronauts Jasmin Moghbeli and Loral O'Hara the slip on Nov. 2, 2023, as they were conducting a spacewalk outside of the International Space Station (ISS).
The tool bag is now orbiting our planet just ahead of the ISS with a visual magnitude of around 6, according to EarthSky. That means it is slightly less bright than the ice giant Uranus, the seventh planet from the sun. As a result, the bag  —  officially known as a crew lock bag  —  is slightly too dim to be visible to the unaided eye, but skywatchers should be able to pick it up with binoculars.
To see it for yourself, first find out when you can find spot the space station over the next few months (NASA even has a new app to help you). The bag should be floating two to four minutes ahead of the station. As it descends rapidly, the bag is likely to disintegrate when it reaches an altitude of around 70 miles (113 kilometers) over Earth.
European Space Agency (ESA) reserve astronaut Meganne Christian shared footage of the moment the tool bag escaped the grasp of Moghbeli on her X account. She added that the bag had last been sighted at that time by Crew-7 astronaut Satoshi Furukawa as it floated high above Mount Fuji.
Also on X, Harvard Center for Astrophysics (CfA) astronomer Jonathan McDowell revealed that the bag is circling Earth in a roughly 258 by 258 mile (415 by 416 kilometer) orbit. McDowell also explained that the bag has also been given its own categorization in the U.S. space force cataloging system for artificial objects in orbit officially designated 58229 / 1998–067WC.
The tool bag joins a vast array of artificial space junk in orbit around Earth, ranging from pieces of shuttles and smashed-up satellites to tools used by astronauts. This isn't even the first tool bag to reach orbit. In 2008, as NASA astronaut Heide Stefanyshyn-Piper attempted to repair a jammed gear on an ISS solar panel, she lost her grip on another tool bag with then circled our planet.
And these definitely aren't the weirdest objects to find their way to orbiting Earth. That honor goes to a humble spatula. Late NASA astronaut Piers Sellers lost his grip on the kitchen implement as he was using it to spread heat-shield repair slime during the space shuttle Discovery's flight STS-121 in 2006.
