Ruée vers l’or à 20 000 lieues sous les mers En 2019, la première mine sous-marine au monde sera mise en exploitation en Océanie. Pour y parvenir, la firme canadienne Nautilus Minerals a dû imaginer des extracteurs hors normes. A la clé, des minerais riches en or, en argent ou en zinc, en proportion dix fois supérieurs à ceux extraits à terre. Jamais les «travailleurs de la mer», magnifiés par Victor Hugo, n’auront relevé un défi aussi exceptionnel. Pour creuser à de telles profondeurs, il a fallu imaginer de ­véritables monstres sous-marins. D’autres projets similaires sont à l’étude.

Mission Overview Studying Mars' Habitability, Seeking Signs of Past Microbial Life, Collecting and Caching Samples, and Preparing for Future Human Missions The Perseverance rover has four science objectives that support the Mars Exploration Program's science goals: All address key astrobiology questions related to the potential of Mars as a place for life. The first three consider the possibility of past microbial life. Mars 2020 Technology: Heritage and Innovation Technologies for Entry, Descent, and Landing The mission uses technological innovations already demonstrated successfully, especially for entry, descent, and landing (EDL). This type of landing system provides the ability to land a very large, heavy rover on the surface of Mars in a more precise landing area than was possible before Curiosity's landing. Technologies for Surface Operations The Perseverance rover design minimizes costs and risks because it is largely based on the engineering design for the previous Curiosity rover.

Le Monde- Février 2020 - L’ espace sous la menace des mégaconstellations de satellites 24 mai 2019, mission Starlink-0 : soixante satellites mis en orbite simultanément. 11 novembre 2019, Starlink-1 : soixante satellites de plus. 7 janvier 2020, Starlink-2 : soixante satellites de plus. 29 janvier, Starlink-3 : soixante satellites de plus. 17 février, Starlink-4 : soixante satellites de plus. Entre-temps, l’opérateur OneWeb est lui aussi entré dans la danse spatiale en lançant sa première fournée de trente-quatre satellites, le 6 février. En mars, Starlink et OneWeb prévoient tous les deux un nouveau lancement. Et ainsi de suite. Il faut s’obliger à lire cette liste monotone de décollages de fusées pour comprendre que le spatial vient, presque subrepticement, d’entrer dans une nouvelle ère, celle des mégaconstellations de satellites, destinées à fournir, depuis l’orbite basse (moins de 2 000 kilomètres d’altitude), du débit Internet à tous les Terriens, partout, tout le temps. Un chiffre qui angoisse aussi.

The Lunar Library: Genesis — Arch Mission Foundation - Preserving humanity fo... The Arch Lunar Library™ represents the first in a series of lunar archives from the Arch Mission Foundation, designed to preserve the records of our civilization for up to billions of years. It is installed in the SpaceIL “Beresheet” lunar lander, which crashed on the Moon in April of 2019. The Lunar Library contains a 30 million page archive of human history and civilization, covering all subjects, cultures, nations, languages, genres, and time periods. The Library is housed within a 100 gram nanotechnology device that resembles a 120mm DVD. The first four layers contain more than 60,000 analog images of pages of books, photographs, illustrations, and documents - etched as 150 to 200 dpi, at increasing levels of magnification, by optical nanolithography. The first analog layer is the Front Cover and is visible to the naked eye. Beneath the analog layers of the Library are 21 layers of 40 micron thick nickel foils, each containing a DVD master.

India Is Headed to the Moon India has successfully launched its second lunar mission, Chandrayaan-2. The country hopes that the launch will make bring it into the exclusive club of nations that have successfully made a soft landing on lunar soil. Riding on an Indian-built rocket known as a Geosynchronous Satellite Launch Vehicle, or GSLV MkIII-M1, the successful launch from the Second Launch Pad at the Satish Dhawan Space Center, located on a small island off India's southeastern coast, took place at 2:43 pm Indian Standard Time (IST). "Today is a historical day for Space Science and Technology in India. The launch wasn't entirely smooth. “Today is the beginning of the historical journey of India towards Moon and to land at a place near south pole to carry out scientific experiments to explore the unexplored. What is Chandrayaan-2? Chandrayaan-2 is a lunar mission comprising of three parts: a lander called Vikram, a rover called Pragyan, and a lunar orbiter. Until today, the mission has been delayed several times.

NASA's Juno spacecraft enters Jupiter's orbit | NASA News Fast Facts The $1.1bn mission will last 20 months Juno has travelled 2.7bn km since its launch in 2011 It's an unmanned solar-powered observatory A key concern are high radiation levels NASA's Juno spacecraft has begun to orbit Jupiter to investigate the origin of the solar system, the US space agency has said. The $1.1bn mission launched five years ago successfully entered the orbit of Jupiter, the largest planet in the solar system, after a 35-minute manoeuvre, NASA said on Tuesday. "Success! The unmanned solar-powered observatory has travelled 2.7bn kilometres since it was launched five years ago from Cape Canaveral in Florida. Once in position to begin its 20-month science mission, Juno will fly in egg-shaped orbits, each one lasting 14 days, to peer through the planet's thick clouds, map its gargantuan magnetic field and probe through the crushing atmosphere for evidence of a dense inner core.

China's Chang'e 4 makes historic first landing on the moon's far side By Leah Crane For the first time, a spacecraft has landed on the side of the moon that is always facing away from Earth – an area that, until now, we had only seen from orbit. The China National Space Administration’s Chang’e 4 lander launched on 7 December and has spent the past month reaching the correct orbit to attempt the historic landing. The CNSA also launched a lunar satellite in May to facilitate communication with the lander, as there is never a direct line of sight between the moon’s far side and Earth. That lack of visibility meant that Chang’e 4 had to make its landing almost completely autonomously, with no input from mission control. At 10.26 am Beijing time on 3 January, the lander successfully touched down on the surface in an enormous depression called the South Pole-Aitken basin. This basin is particularly important because it is thought to be a crater from a huge impact during the moon’s early years. The mission will also help prepare for the moon’s possible future.

New Horizons Spacecraft Wakes Up to Prepare for Historic Flyby of Distant Object NASA's New Horizons spacecraft has woken up from hibernation to prepare for a historic New Year's Day flyby at the edge of our solar system. The New Horizons probe, which flew by Pluto in July 2015, has been in hibernation mode since Dec. 21 to preserve resources. But, on June 5, the mission operations team at Johns Hopkins Applied Physics Laboratory received confirmation, through NASA's Deep Space Network, that the spacecraft had exited hibernation, as it was programmed to do. The spacecraft will now begin preparations for a New Year's flyby encounter with the farthest planetary encounter in history. "Our team is already deep into planning and simulations of our upcoming flyby of Ultima Thule and excited that New Horizons is now back in an active state to ready the bird for flyby operations," the mission's principal investigator, Alan Stern, of the Southwest Research Institute in Boulder, Colorado, said in a statement.
