Low Energy Transfers
A low-energy transfer, or low-energy trajectory, is a route in space that allows spacecraft to change orbits using significantly less fuel than traditional transfers. These routes work in the Earth–Moon system and also in other systems, such as between the moons of Jupiter. The drawback of such trajectories is that they take longer to complete than higher-energy (more-fuel) transfers, such as Hohmann transfer orbits. Low-energy transfers are also known as Weak Stability Boundary trajectories, and include ballistic capture trajectories. Low-energy transfers follow special pathways in space, sometimes referred to as the Interplanetary Transport Network. Following these pathways allows for long distances to be traversed for little change in velocity, or . Example missions Missions that have used low-energy transfers include: * '' Hiten'', from JAXA * '' SMART-1'', from ESA * '' Genesis'', from NASA.

Animation Of GRAIL-A Trajectory
Animation is a method by which still figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI). Computer animation can be very detailed 3D animation, while 2D computer animation (which may have the look of traditional animation) can be used for stylistic reasons, low bandwidth, or faster real-time renderings. Other common animation methods apply a stop motion technique to two- and three-dimensional objects like paper cutouts, puppets, or clay figures. A cartoon is an animated film, usually a short film, featuring an exaggerated visual style. The style takes inspiration from comic strips, often featuring anthropomorphic animals, superheroes, or the adventures of human protagonists. Especially with animals that form a natural predator/prey relationship (e.g. cats and mice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Discover (magazine)
''Discover'' is an American general audience science magazine launched in October 1980 by Time Inc. It has been owned by Kalmbach Publishing since 2010. History Founding ''Discover'' was created primarily through the efforts of ''Time'' magazine editor Leon Jaroff. He noticed that magazine sales jumped every time the cover featured a science topic. Jaroff interpreted this as a considerable public interest in science, and in 1971, he began agitating for the creation of a science-oriented magazine. This was difficult, as a former colleague noted, because "Selling science to people who graduated to be managers was very difficult".Hevesi, Dennis"Leon Jaroff, Editor at Time and Discover Magazines, Dies at 85" ''The New York Times'', 21 October 2012 Jaroff's persistence finally paid off, and ''Discover'' magazine published its first edition in 1980. ''Discover'' was originally launched into a burgeoning market for science magazines aimed at educated non-professionals, intended to ...

Mars Direct
Mars Direct is a proposal for a human mission to Mars which purports to be both cost-effective and possible with current technology. It was originally detailed in a research paper by Martin Marietta engineers Robert Zubrin and David Baker in 1990, and later expanded upon in Zubrin's 1996 book ''The Case for Mars''. It now serves as a staple of Zubrin's speaking engagements and general advocacy as head of the Mars Society, an organization devoted to the colonization of Mars. History Space Exploration Initiative On July 20, 1989, US President George H. W. Bush announced plans for what came to be known as the Space Exploration Initiative (SEI). In a speech on the steps of the National Air and Space Museum he described long-term plans which would culminate in a human mission to the surface of Mars. By December 1990, a study to estimate the project's cost determined that long-term expenditure would total approximately 450 billion dollars spread over 20 to 30 years. The "90 Day St ...

European Student Moon Orbiter
The European Student Moon Orbiter (ESMO) was a proposed European student mission to the Moon. Student teams from 19 universities throughout Europe worked on the program. ESMO was conceived by the Student Space Exploration & Technology Initiative (SSETI) under the support of the European Space Agency (ESA); prior to the start of Phase A the full responsibility for the management of the program was transferred to the ESA Education Office. In 2009, Surrey Satellite Technology Ltd (SSTL) was selected as prime contractor. In April 2012, ESMO was scheduled for launch in 2014 or 2015, but further ESA evaluation deemed the ESMO project's costs "unsustainable" given the ESA Education Office's budget. Objectives The mission objectives for ESMO were: * To launch the first lunar spacecraft to be designed, built and operated by students across ESA Member States and ESA Cooperating States * To place and operate the spacecraft in a lunar orbit * To acquire images of the Moon from a stable ...

Danuri
The Korea Pathfinder Lunar Orbiter (KPLO), officially Danuri, is South Korea's first lunar orbiter. The orbiter, its science payload and ground control infrastructure are technology demonstrators. The orbiter will also be tasked with surveying lunar resources such as water ice, uranium, helium-3, silicon, and aluminium, and produce a topographic map to help select future lunar landing sites. The mission was launched on 4 August 2022 on a Falcon 9 Block 5 launch vehicle. It was inserted into orbit around the Moon on 16 December 2022 (UTC). Name On 23 May 2022, the South Korean Ministry of Science and ICT officially named the Korea Pathfinder Lunar Orbiter (시험용 달 궤도선, 試驗用月軌道船) as "Danuri" (다누리). Danuri is a portmanteau of two Korean words, ''dal'' (달) which means moon and ''nurida'' (누리다) which means enjoy. According to the ministry, this new name implies a big hope and desire for the success of South Korea's first Moon mis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CAPSTONE
CAPSTONE (Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment) is a lunar orbiter that will test and verify the calculated orbital stability planned for the Lunar Gateway space station. The spacecraft is a 12-unit CubeSat that will also test a navigation system that will measure its position relative to NASA's Lunar Reconnaissance Orbiter (LRO) without relying on ground stations. It was launched on 28 June 2022, arrived in lunar orbit on 14 November 2022, and is scheduled to orbit for six months. Background The Lunar Gateway is an in-development space station being planned by several national space agencies since at least 2018, including NASA, European Space Agency (ESA) and Canadian Space Agency (CSA).
