Space Jellyfish
A space jellyfish (also jellyfish UFO or rocket jellyfish) is a rocket launch-related phenomenon caused by sunlight reflecting off the high-altitude rocket plume gases emitted by a launching rocket during morning or evening twilight. The observer is in darkness, while the exhaust plumes at high altitudes are still in direct sunlight. This luminous apparition is reminiscent of a jellyfish. Sightings of the phenomenon have led to panic, fear of nuclear missile strike, and reports of unidentified flying objects.

Rocket Launch
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Significa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Progress MS-17
Progress MS-17 (), Russian production No. 446, identified by NASA as Progress 78P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). This was the 169th flight of a Progress spacecraft. History The Progress-MS is a crew-less freighter based on the Progress-M featuring improved avionics. This improved variant was first launched on 21 December 2015. It has the following improvements: * The new external compartment enables it to deploy satellites. Each compartment can hold up to four launch containers. First time installed on Progress MS-03. * Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism. * Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment. * Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations. * GNSS autonomous navigation enables real- ...

Plesetsk Cosmodrome
Plesetsk Cosmodrome () is a Russian spaceport located in Mirny, Arkhangelsk Oblast, near the town of Plesetsk, from which it takes its name. Until 2025 and the commissioning of the Andøya Space, Andøya base in Norway, it was the only operational orbital spaceport in Europe and the northernmost spaceport in the world. Originally developed as an intercontinental ballistic missile (ICBM) site for the R-7 (missile), R-7 missile, its strategic location approximately north of Moscow was key to its selection. Due to its high latitude, Plesetsk is particularly suited for specific types of satellite launches, such as those into Molniya orbits, and historically served as a secondary launch facility. Most Soviet orbital launches were conducted from Baikonur Cosmodrome, located in the Kazakh SSR. However, following the dissolution of the Soviet Union, Baikonur became part of Kazakhstan, which began charging Russia to lease the land for its use. As a result, Plesetsk has seen significant ...

Glonass-M
GLONASS-M (), also known as Uragan-M () (GRAU index 11F654M given to the first two pilot satellites and 14F113 to the rest) are the second generation of Uragan satellite design used as part of the Russian GLONASS radio-based satellite navigation system. Developed by ISS Reshetnev (Information Satellite Systems Reshetnev), it had its debut launch in 2003, and is in the process of being phased out. Its production finished in 2015 and its last launch was in November 2022. It is an evolution of the previous Uragan (GRAU Index 11F654) second-generation satellites, improving accuracy, increasing power, extending the design life and adding the FDMA L2OF open signal. The last eight Glonass-M spacecraft in production included the new CDMA L3OC open signal. Design It used a 3-axis stabilized pressurized bus with two solar panels, a propulsion module and a payload module. At these are just heavier than the previous generation, but have 25% more power 1250 W, 230% more design life (7 ye ...

SpaceX CRS-15
SpaceX CRS-15, also known as SpX-15, was a Commercial Resupply Service mission to the International Space Station launched 29 June 2018 aboard a Falcon 9 rocket. The mission was contracted by NASA and flown by SpaceX. Launch In early 2015, NASA awarded a contract extension to SpaceX for three additional CRS missions ( CRS-13 to CRS-15). In June 2016, a NASA Inspector General report had this mission manifested for April 2018, but this was pushed back, first to 6 June, to 9 June, to 28 June and finally to 29 June 2018. The mission launched on 29 June 2018 at 09:42 UTC aboard a Falcon 9 rocket from Cape Canaveral Air Force Station Launch Complex 40. The SpaceX Dragon spacecraft rendezvoused with the International Space Station on 2 July 2018. It was captured by the Canadarm2 at 10:54 UTC and was berthed to the ''Harmony'' node at 13:50 UTC. On 3 August 2018, Dragon was released from ISS at 16:38 UTC and deorbited, splashing down in the Pacific Ocean appro ...

Falcon 9 Flight 57
Falcons () are birds of prey in the genus ''Falco'', which includes about 40 species. Some small species of falcons with long, narrow bird wing, wings are called hobby (bird), hobbies, and some that hover (behaviour)#Wind hoverers, hover while hunting are called kestrels. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene. Adult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a wikt:broadwing, broadwing. This makes flying easier while still learning the aerial skills required to be effective hunters like the adults. The falcons are the largest genus in the Falconinae subfamily of Falconidae, which also includes two other subfamilies comprising caracara (subfamily), caracaras and ...
