2024 In Spaceflight
2024 saw new world records for orbital launch attempts and successful orbital launches for the fourth consecutive year. Notable milestones included the successful maiden launches of the American Vulcan Centaur and China's Gravity-1, and Long March 12 rockets. The European Ariane 6 rocket also conducted its inaugural flight, though it experienced a partial failure. SpaceX advanced its Starship development, with flight test 5 achieving the first landing of its first stage. Additionally, the final launch of a Delta family rocket, a Delta IV Heavy variant, occurred in April. In September, the private Polaris Dawn mission made history by performing the first commercial spacewalk, during which two crew members exited their Crew Dragon spacecraft. This mission set a new record for the number of individuals—four—simultaneously exposed to the vacuum of space. Two significant scientific missions were launched in October: NASA's Europa Clipper to Jupiter's moon Europa to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta IV Heavy
The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It had the highest capacity of any operational launch vehicle in the world after the retirement of the Space Shuttle in 2011 until the Falcon Heavy debuted in 2018, and it was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024. It was manufactured by United Launch Alliance (ULA) and was first launched in 2004. Delta IV Heavy was the last operating member of the Delta IV family, and its final flight was on 9 April 2024. It is succeeded by the Vulcan Centaur rocket. The Delta IV Heavy first stage consisted of a central Common Booster Core (CBC), with two additional CBCs as liquid rocket boosters instead of the GEM-60 solid rocket motors used by the Delta IV Medium+ versions. At lift-off, all three rocket engines would operate at full thrust, and 44 seconds later the central engine would throttle down to 5 ...

Spacewalk
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable atmosphere of Earth, Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and Moon, lunar or planetary surface exploration (commonly known from 1969 to 1972 as moonwalks). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVAs have been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. In 1984, Svetlana Savitskaya became the first woman to perform a spacewalk, conducting EVA outside the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polaris Dawn
Polaris Dawn was a Private spaceflight, private crewed spaceflight operated by SpaceX on behalf of Shift4 CEO Jared Isaacman, the first of three planned missions in the Polaris program. Launched 10 September 2024 as the 14th crewed orbital flight of a Crew Dragon spacecraft, Isaacman and his crew of three — Scott Poteet, Sarah Gillis and Anna Menon — flew in an elliptic orbit that took them away from Earth, the farthest anyone has been since NASA's Apollo program. They passed through parts of the Van Allen radiation belt to study the Health threat from cosmic rays, health effects of space radiation and spaceflight on the human body. Later in the mission, the crew performed the first commercial Extravehicular activity, spacewalk. The Polaris Dawn mission also marked several other milestones. Menon and Gillis flew further from Earth than any women before them and Gillis, at 30 years old, became the youngest person to date to participate in a spacewalk. During the spacewalk, a n ...

Delta (rocket Family)
The Delta rocket family was a versatile range of American rocket-powered expendable launch systems that provided space launch capability in the United States from 1960 to 2024. Japan also launched license-built derivatives ( N-I, N-II, and H-I) from 1975 to 1992. More than 300 Delta rockets were launched with a 95% success rate. The series was phased out in favor of the Vulcan Centaur, with the Delta IV Heavy rocket's last launch occurring on April 9, 2024. Origins The original Delta rockets used a modified version of the PGM-17 Thor, the first ballistic missile deployed by the United States Air Force (USAF), as their first stage. The Thor had been designed in the mid-1950s to reach Moscow from bases in Britain or similar allied nations, and the first wholly successful Thor launch had occurred in September 1957. Subsequent satellite and space probe flights soon followed, using a Thor first stage with several different upper stages. The fourth upper-stage combinatio ...

Vulcan Centaur
Vulcan Centaur is a heavy-lift launch vehicle developed and operated by United Launch Alliance (ULA). It is a two-stage-to-orbit launch vehicle consisting of the Vulcan first stage and the Centaur second stage. Replacing ULA's Atlas V and Delta IV rockets, the Vulcan Centaur is principally designed to meet the needs of the National Security Space Launch (NSSL) program, which supports U.S. intelligence agencies and the Defense Department, but ULA believes it will also be able to price missions low enough to attract commercial launches. ULA began development of the new launch vehicle in 2014, primarily to compete with SpaceX’s Falcon 9 and to comply with a Congressional mandate to phase out the use of the Russian-made RD-180 engine that powered the Atlas V. The first launch of the Vulcan Centaur was initially scheduled for 2019 but faced multiple delays due to developmental challenges with its new BE-4 first-stage engine and the Centaur second-stage. The Vulcan Centaur had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Timeline Of Spaceflight
This is a timeline of known spaceflights, both crewed and uncrewed, sorted chronologically by launch date. Due to its large size, the timeline has been split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951. The list for the year and for its subsequent years may contain planned launches, but the statistics will only include past launches. For the purpose of these lists, a spaceflight is defined as any flight that crosses the Kármán line, the Fédération Aéronautique Internationale, FAI-recognized edge of space, which is Above mean sea level, above mean sea level (AMSL). The timeline contains all the flights which have either crossed the edge of space, were intended to do so but failed, or are planned in the near future. Notable test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided into orbital launches (sending a payload into ...
