ODINUS
ODINUS (Origins, Dynamics, and Interiors of the Neptunian and Uranian Systems) is a space mission concept proposed to the European Space Agency's Cosmic Vision programme. The ODINUS mission concept proposes to expand the Uranus orbiter and probe mission to two twin orbiters— dubbed ''Freyr'' and ''Freyja'', the twin gods of the Norse pantheon. Their primary mission would be to study Neptune and Uranus with one orbiter each. If selected, ODINUS would launch in 2034. Instruments The following six instruments are considered essential to the mission: *Camera (Wide and Narrow Angle) – Designed to image the planet at the same level of detail as missions to the two gas giants have provided. *VIS-NIR Image Spectrometer *Magnetometer – To study the magnetic fields of Neptune. *Mass Spectrometer (Ions and Neutrals, INMS) *Doppler Spectro-Imager – To take seismic measurements. *Microwave Radiometer The following two additional instruments are strongly desired by the mission propos ...

Exploration Of Neptune
Neptune has been directly explored by one space probe, ''Voyager 2'', in 1989. , there are no confirmed future missions to visit the Neptunian system, although a tentative Chinese mission has been planned for launch. NASA, ESA, and independent academic groups have proposed future scientific missions to visit Neptune. Some mission plans are still active, while others have been abandoned or put on hold. Since the mid-1990s, Neptune has been studied from afar with telescopes, including the Hubble Space Telescope and the ground-based Keck telescope using adaptive optics. ''Voyager 2'' After ''Voyager 2'' visited Saturn successfully, it was decided to fund further missions to Uranus and Neptune. These missions were conducted by the Jet Propulsion Laboratory, and the Neptunian mission was dubbed "Voyager Neptune Interstellar Mission". ''Voyager 2'' started taking navigation images of Neptune in May 1988. ''Voyager 2'' observation phase proper of Neptune began 5 June 1989, the spa ...

Exploration Of Uranus
The exploration of Uranus has, to date, been through telescopes and a lone probe by NASA's ''Voyager 2'' spacecraft, which made its closest approach to Uranus on January 24, 1986. ''Voyager 2'' discovered 10 moons, studied the planet's cold atmosphere, and examined its ring system, discovering two new rings. It also imaged Uranus's five large moons, revealing that their surfaces are covered with impact craters and canyons. A number of dedicated exploratory missions to Uranus have been proposed, but none have been approved. ''Voyager 2'' ''Voyager 2'' made its closest approach to Uranus on January 24, 1986, coming within of the planet's cloud tops. This was the probe's first solo planetary flyby, since ''Voyager 1'' ended its tour of the outer planets at Saturn's moon Titan. Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about and completes one orbit every 84 years. The length of a day on Uranus as measured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranus Orbiter And Probe
The Uranus Orbiter and Probe is an orbiter mission concept to study Uranus and its moons. The orbiter would also deploy an atmospheric probe to characterize Uranus's atmosphere. The concept is being developed as a potential large strategic science mission for NASA. The science phase would last 4.5 years and include multiple flybys of each of the major moons. The mission concept was selected as the highest priority Flagship-class mission by the 2023–2032 Planetary Science Decadal Survey, ahead of the Enceladus Orbilander. A Neptune orbiter mission concept, Neptune Odyssey, that would address many of the same scientific goals regarding ice giants was also considered, but for logistical and cost reasons a mission to Uranus was favored. The original proposal targeted a launch in 2031 using a Falcon Heavy expendable launch vehicle with a gravity assist at Jupiter, allowing arrival at Uranus in 2044. In 2023, however, NASA announced that due to a shortfall in plutonium produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranus Pathfinder
Uranus Pathfinder was a mission concept for the Uranian system evaluated in the 2010s by the European Space Agency. In 2011, scientists from the Mullard Space Science Laboratory in the United Kingdom proposed the joint NASA–ESA ''Uranus Pathfinder'' mission to Uranus. It would have been a medium-class (M-class) mission to be launched in 2022, and was submitted to the ESA in December 2010 with the signatures of 120 scientists from around the globe. ESA caps the cost of M-class missions at €470 million. Uranus Pathfinder was proposed in support of ESA's Cosmic Vision 2015–2025. The mission study including several possible combinations of launch dates, trajectories, and flybys (gravity assists), including flybys of Earth, Venus, and of the planet Saturn. Indeed, the study noted the velocity change requirements are only marginally higher than for typical missions to Saturn of this period. In the baseline concept, UP is an ESA–NASA bilateral mission and it would launch on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MUSE (spacecraft)
MUSE (Mission to Uranus for Science and Exploration) is a European proposal for a dedicated mission to the planet Uranus to study its atmosphere, interior, moons, rings, and magnetosphere. It is proposed to be launched with an Ariane 6 in 2026, travel for 16.5 years to reach Uranus in 2044, and would operate until 2050. The European Space Operations Centre would monitor and control the mission, as well as generate and provide the raw data sets. In 2012, the cost was estimated at €1.8 billion. The mission addresses the themes of the ESA Cosmic Vision 2015–2025. This was designed as an L-Class flagship level mission; however, it is constrained by the need for RTGs. MUSE was also analyzed in the US as an Enhanced New Frontiers class mission in 2014. Orbiter The orbiter science phase would consist of the Uranus Science Orbit (USO) phase of approximately 2 years in a highly elliptic polar orbit to provide best gravimetry data, during which 36 Uranus orbits are performed.

OCEANUS
In Greek mythology, Oceanus ( ; , also , , or ) was a Titans, Titan son of Uranus (mythology), Uranus and Gaia, the husband of his sister the Titan Tethys (mythology), Tethys, and the father of the River gods (Greek mythology), river gods and the Oceanids, as well as being the great river which encircled the entire world. Etymology According to M. L. West, the etymology of Oceanus is "obscure" and "cannot be explained from Greek". The use by Pherecydes of Syros of the form () for the name lends support for the name being a loanword. However, according to West, no "very convincing" foreign models have been found. A Semitic derivation has been suggested by several scholars, while R. S. P. Beekes has suggested a loanword from the Aegean Pre-Greek non-Indo-European Stratum (linguistics), substrate. Nevertheless, Michael Janda sees possible Indo-European connections. Genealogy Oceanus was the eldest of the Titan offspring of Uranus (Sky) and Gaia (Earth). Hesiod lists his T ...

Neptune
Neptune is the eighth and farthest known planet from the Sun. It is the List of Solar System objects by size, fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth. Compared to Uranus, its neighbouring ice giant, Neptune is slightly smaller, but more massive and denser. Being composed primarily of gases and liquids, it has no well-defined solid surface. Neptune orbits the Sun once every 164.8 julian year (astronomy), years at an orbital distance of . It is named after Neptune (mythology), the Roman god of the sea and has the astronomical symbol representing Trident of Poseidon, Neptune's trident. Neptune is not visible to the unaided eye and is the only planet in the Solar System that was not initially observed by direct empirical observation. Rather, unexpected changes in the orbit of Uranus led Alexis Bouvard to hypothesise that its orbit was subject to gravitational Pe ...

Uranus
Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a Supercritical fluid, supercritical phase of matter, which astronomy calls "ice" or Volatile (astrogeology), volatiles. Atmosphere of Uranus, The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature () of all the Solar System's planets. It has a marked axial tilt of 82.23° with a Retrograde and prograde motion, retrograde rotation period of 17 hours and 14 minutes. This means that in an 84-Earth-year orbital period around the Sun, its poles get around 42 years of continuous sunlight, followed by 42 years of continuous darkness. Uranus has the third-largest diameter and fourth-largest mass among the Solar System's planets. Based on current models, inside its volatile Mantle (geology), mantle layer is a rocky core, and surrounding it is a thick hydrogen and helium atmosphere. Trace amount ...
