Ramses (spacecraft)
Ramses, or Rapid Apophis Mission for Space Safety, is a proposed European Space Agency (ESA) mission to a near-Earth asteroid 99942 Apophis. If approved, it is expected to be launched in April 2028 and to arrive at Apophis in February 2029 before its closest approach to Earth. It will conduct multiple measurements of the asteroid's properties, to study possible response in case such an asteroid would be on a collision course with Earth. Ramses mission will leverage much of the technology developed for the ''Hera'' mission. At the asteroid, Ramses will deploy two smaller CubeSats. The decision whether to approve the mission is expected to take place at ESA’s Ministerial Council Meeting in November 2025. CubeSats The first selected CubeSat will be built by Tyvak International, a company that developed the ''Milani'' CubeSat for the ''Hera'' mission. The small spacecraft will combine the dust analyser of ''Milani'' with the low-frequency radar of ''Juventas'', another CubeSat o ...

Apophis Pass
Apophis (; ), also known as Apep () or Aphoph (, ) Erman, Adolf, and Hermann Grapow, eds. 1926–1953. ''Wörterbuch der aegyptischen Sprache im Auftrage der deutschen Akademien''. 6 vols. Leipzig: J. C. Hinrichs'schen Buchhandlungen. (Reprinted Berlin: Akademie-Verlag GmbH, 1971). is the ancient Egyptian deity who embodied darkness and disorder, and was thus the opponent of light and Maat (order/truth). Ra was the bringer of light and hence the biggest opposer of Apophis. Features Because Ra was the solar deity, bringer of light, and thus the upholder of Maat, Apophis was viewed as the greatest enemy of Ra, and thus was given the title ''Enemy of Ra'', and also "the Lord of Chaos". "The Lord of Chaos" was seen as a giant snake or serpent leading to such titles as ''Serpent from the Nile'' and ''Evil Dragon''. Some elaborations said that he stretched 16 yards in length and had a head made of flint. Presented on a Naqada I (c. 4000–3550 BCE) C-ware bowl (now in C ...

European Space Agency
The European Space Agency (ESA) is a 23-member International organization, international organization devoted to space exploration. With its headquarters in Paris and a staff of around 2,547 people globally as of 2023, ESA was founded in 1975 in the context of European integration. Its 2025 annual budget was €7.7 billion. The ESA Human and Robotic Exploration programme includes human spaceflight (mainly through participation in the International Space Station programme); as well as the launch and operation of missions to Mars and Moon. Further activities include science missions to Jupiter, Mercury, the Sun, Earth observation, Asteroid impact avoidance and Telecommunications missions, designing launch vehicles; and maintaining Europe's Spaceport, the Guiana Space Centre at Kourou (French Guiana). Further programmes include space safety, satellite navigation, applications and commercialisation. The main European launch vehicle Ariane 6 is operated through Arianespace ...

Near-Earth Asteroid
A near-Earth object (NEO) is any small Solar System body orbiting the Sun whose closest approach to the Sun (perihelion) is less than 1.3 times the Earth–Sun distance (astronomical unit, AU). This definition applies to the object's orbit around the Sun, rather than its current position, thus an object with such an orbit is considered an NEO even at times when it is far from making a close approach of Earth. If an NEO's orbit crosses the Earth's orbit, and the object is larger than across, it is considered a potentially hazardous object (PHO). Most known PHOs and NEOs are asteroids, but about a third of a percent are comets. There are over 37,000 known near-Earth asteroids (NEAs) and over 120 known short-period near-Earth comets (NECs). A number of solar-orbiting meteoroids were large enough to be tracked in space before striking Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of Earth. ...

99942 Apophis
99942 Apophis ( provisional designation ) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, that caused a brief period of concern in December 2004 when initial observations indicated a probability of 0.027 (2.7%) that it would hit Earth on Friday, April 13, 2029. Additional observations provided improved predictions that eliminated the possibility of an impact on Earth in 2029. A small possibility nevertheless remained that, during its 2029 close encounter with Earth, Apophis would pass through a gravitational keyhole estimated to be 800 metres in diameter, which would have set up a future impact exactly seven years later on Easter Sunday, April 13, 2036. This possibility kept it at Level 1 on the 0 to 10 Torino impact hazard scale until August 2006, when the probability that Apophis would pass through the keyhole was determined to be very small and Apophis's rating on the Torino scale was lowe ...

Hera (space Mission)
''Hera'' is a spacecraft developed by the European Space Agency for its space safety program. Its primary mission objective is to study the Didymos binary asteroid system that was impacted four years earlier by the NASA Double Asteroid Redirection Test (DART) spacecraft and contribute to validation of the kinetic impact method to deviate a near-Earth asteroid from a colliding trajectory with Earth. It will measure the size and morphology of the crater created as well as the momentum transferred by an artificial projectile impacting an asteroid, which will allow measuring the efficiency of the deflection produced by the impact. It will also analyze the expanding debris cloud caused by the impact. ''Hera'' is intended to fully characterize the composition and physical properties of the binary asteroid system including, for the first time, the sub-surface and internal structures. It will also perform technological demonstrations linked to operations in the vicinity of a small So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tyvak
Tyvak Nano-Satellite Systems was an American company that designed and built satellites. It started as a designer, builder and provider of nanosatellite and CubeSat space vehicle products and services for government and commercial customers. Tyvak was based in Irvine, California. It was a subsidiary of Terran Orbital Corporation. In 2022, it was announced that Tyvak would transition into larger satellites from nanosats and cubesats and the name Tyvak would be phased out in favor of the name of the parent company Terran Orbital. In 2011, Jordi Puig-Suari, co-inventor of the CubeSat design, and Scott MacGillivray, former manager of nanosatellite programs for Boeing Phantom Works, established Tyvak Nano-Satellite Systems in San Luis Obispo, California, to sell miniature avionics packages for small satellites, with the goal to increase the volume available for payloads. On 18 November 2019, Tyvak was one of five companies selected to be eligible to bid for the NASA Commercial Luna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of European Space Agency Programmes And Missions
The European Space Agency (ESA) operates a number of space missions, both individually and in collaborations with other space agencies such as Japanese JAXA, U.S. NASA, Chinese CNSA, as well as space agencies of ESA member states (eg. French CNES, Italian ASI, German DLR, Polish POLSA). A staple of the ESA's Science Doctrine is the Cosmic Vision Programme, a series of space science missions chosen by ESA to launch through competitions, similar to NASA's Discovery and New Frontiers programmes. It follows the Horizon 2000 and Horizon 2000+ programmes which launched notable missions such as '' Huygens'' (Titan lander), ''Rosetta'' (comet orbiter and lander), and ''Gaia'' (astrometry telescope). These missions are divided into two categories: "Sun and Solar System", space probes studying the Solar System (eg. Solar Orbiter studying the Sun and JUICE currently on its way to Jupiter) and "Astrophysics", space telescopes contributing to interstellar astronomy (eg. CHEOPS charact ...
