Some schools of thought hold that modernity ended in the late 20th century – in the 1980s or early 1990s – and that it was replaced by postmodernity, and still others would extend modernity to cover the developments denoted by postmodernity, while some believe that modernity ended sometime after World War II. Postmodernity ( post-modernity or the postmodern condition) is the economic or cultural state or condition of society which is said to exist after modernity.

In an op-ed for Scientific American, Planetary Society chief advocate Casey Dreier makes the argument that to defend against both kinds of disaster, we have to make investments well in advance.

Just a week after launching, the solar sailing spacecraft succeeded at raising the high point of its orbitĪround the Earth using only sunlight for propulsion.

Recent studies of Cassini mission data show that Saturn’s icy moon ejects plumes containing higher levels of hydrogen, carbon dioxide and methane than previously thought, piquing curiosity about what’s happening inside the moon’s subsurface ocean. Pictured: NASA’s mission logos for Apollo (left) and Artemis (right). Apollo historian and author Andrew Chaikin joins this week’s Planetary Radio to talk about the legacy of humanity’s first visits to the Moon, what we can expect from NASA’s plans to return, and much more. Much like siblings, the Apollo and Artemis programs to send humans to the Moon have similarities as well as stark differences. In Greek mythology, Apollo and Artemis were the twin children of the god Zeus. As of Thursday afternoon NASA reported the situation was under control.Īpollo made giant leaps, and Artemis aims to follow suit. The trouble didn't end there: once attached, Nauka began firing its thrusters uncontrollably, knocking the entire station out of alignment by 45 degrees.
The module overcame communications and propulsion problems following launch on July 21 before successfully docking with the station on July 29. Russia's new Nauka science module is attached to the International Space Station after some last-minute drama. In April, NASA selected SpaceX as the recipient of its Human Landing System (HLS) contract, a decision that competitors Blue Origin and Dynetics protested shortly after. In a letter to NASA Administrator Bill Nelson, Blue Origin founder Jeff Bezos said his company is willing to waive up to $2 billion in payments over the current and next two government fiscal years in exchange for a fixed-priced contract.
The discovery is just in time for the European Space Agency's upcoming JUICE mission, which launches in 2022 to study Ganymede and other Jovian moons.īlue Origin says it’s willing to cover $2 billion of the cost for a second lunar lander contract, should NASA award one.

Astronomers revisiting archive Hubble data have found evidence of water vapor in the Jovian moon’s atmosphere. Hubble might have solved an age-old mystery about Ganymede. It’ll also investigate whether the world has the right conditions for life. Europa Clipper will produce high-resolution images of Jupiter’s icy moon Europa and explore its geographical features. The Planetary Society previously urged Congress to drop a directive that required Europa Clipper to launch on the Space Launch System, and instead allow NASA to select the best rocket for the job. NASA has selected SpaceX to provide launch services for the Europa Clipper, which is now slated to launch in October 2024 on a Falcon Heavy rocket. Europa Clipper finally has a launch vehicle.
