Ramlaen Posted July 15, 2018 Report Share Posted July 15, 2018 Scarcely 48 hours after they began, SpaceX technicians have already completed installation of all four of Falcon fairing recovery vessel Mr Steven’s new and dramatically larger arms, as well as eight giant struts. All that remains to be installed is an upgraded net, said by CEO Elon Musk to have four times the area of its predecessor. Quote Link to comment Share on other sites More sharing options...

LostCosmonaut Posted July 25, 2018 Report Share Posted July 25, 2018 Lake Vostok, but on Mars; https://twitter.com/esascience/status/1022121137516552194 This definitely isn't conclusive evidence that life exists (or has existed on Mars), but it's interesting. Some extremophile bacteria were found in Lake Vostok water samples a while back; https://en.wikipedia.org/wiki/Hydrogenophilaceae But they were a hot-water species, so they're either a surface contaminant, or there's a hydrothermal vent somewhere in Lake Vostok. I don't think it's 100% certain that life would survive an under-ice lake away from a major heat source. Ramlaen 1 Quote Link to comment Share on other sites More sharing options...

Ramlaen Posted August 6, 2018 Report Share Posted August 6, 2018 A planet over 12 times bigger than Jupiter has been found drifting alone through space around 20 light years away from Earth. Quote The rogue world is not attached to any star, and is the first object of its kind to be discovered using a radio telescope. Both its mass and the enormous strength of its magnetic field challenge what scientists know about the variety of astronomical objects found in the depths of space. “This object is right at the boundary between a planet and a brown dwarf, or ‘failed star’, and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets,” said Dr Melodie Kao, an astronomer at Arizona State University. Brown dwarves are difficult objects to categorise – they are both too huge to be considered planets and not big enough to be considered stars. Originally detected in 2016 using the Very Large Array (VLA) telescope in New Mexico, the newly identified planet was initially considered a brown dwarf. Quote The boundary often used to distinguish a massive gas giant plant from a brown dwarf is the “deuterium-burning limit” – the mass below which the element deuterium stops being fused in the objects core. This limit is around 13 Jupiter masses, so at 12.7 the newly identified planet was brushing up against it. Quote Similar to the aurora borealis or northern lights seen on Earth, this planet and some brown dwarves are known to have auroras of their own – despite lacking the solar winds that traditionally drive them. It is the radio signature of these auroras that allowed the researchers to detect these distant objects in the first place, but it is still unclear how they are being formed. However, the research team’s analysis showed the planet’s magnetic field is incredibly strong, around 200 times stronger than Jupiter’s, and this could help explain why it also has a strong aurora. “This particular object is exciting because studying its magnetic dynamo mechanisms can give us new insights on how the same type of mechanisms can operate in extrasolar planets – planets beyond our solar system,” explained Dr Kao. “We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets,” she said.

Wasn't Vzglyad, but nobody cares https://ria.ru/space/20180808/1526134018.html Quote The rocket of increased carrying capacity "Angara-A5V" can be reusable, believes the general designer of launch vehicles, one of the ideologists of the Angara missile Alexander Medvedev. In his opinion, the rocket can land on retractable supports, like the Falcon 9. /.../ According to Medvedev's concept, after the start, the first and second stages (the four side blocks of the first stage and the central unit - the second one) without separation from each other, as it should be when starting the "one-time" "Angara", continue to fly until the third stage is separated from them with a spacecraft. Then the third stage continues the flight according to the program, and flies down. Before landing, the central unit and the rocket "sits" on the telescopic supports, like the Falcon 9 rocket from SpaceX. /.../ After completion of rocket, the Angara-A5V will be able to move 26-27 tons from the Vostochniy Cosmodrome, rather than 37 tons in single use option. /.../ [Rocket can land] on a floating platform in the Sea of Okhotsk 1,360 kilometers from the cosmodrome.

LostCosmonaut Posted August 9, 2018 Report Share Posted August 9, 2018 Everyone's getting on the reusability train! This is a good idea though, now that it's been proven that landing stages (at sea or on land) is feasible, I'd be surprised if any new projects from this point forward didn't incorporate it. Aside from maybe any very small launchers that get built. It boggles the mind that Vulcan is just going with catching the engines (and to my knowledge haven't done any actual testing on it, SpaceX had the Grasshopper for a few years before landing F9).

Ramlaen Posted August 10, 2018 Report Share Posted August 10, 2018 Space Shuttle Door Gunners are a step closer to being a real thing. The US Congress required the Pentagon to make a report on the 'organizational and management structure for the national security space components of the Department of Defense (DoD)', and they went ahead and laid out a roadmap to standing up a Space Force branch of the military in FY2020. Quote Leadership and critical alignment within the Executive Branch and the Legislative Branch provide a window of time to drive significant change in the space enterprise and establish a new Space Force with a generational leap forward in capability. The Space Force will follow the National Defense Strategy to accelerate new capabilities. This will grow the commercial space industry and protect U.S. vital interests. The pace of change will be governed by technology – not held back by organization. The new Space Development Agency will scale the skills, mindset, and approach of DoD innovative organizations like the Strategic Capabilities Office and the Air Force Rapid Capabilities Office to develop capabilities at speed, and marry commercial technology and industry with government development. The new U.S. Space Command will merge this new technology with warfighters dedicated to innovating, experimenting and evolving the Department’s warfighting concepts. The Space Development Agency will first integrate with the Space Operations Force and eventually with service support functions and authorities to become the Space Force. The Space Force will unlock our potential and lead to outcomes never before thought possible. Donward 1 Quote Link to comment Share on other sites More sharing options...

Quote MOSCOW, September 12 (Itar-Tass) - RIA Novosti. Commission of Roskosmos, investigating the incident with depressurization on the Soyuz spacecraft, as a priority, considers the version of the intentional damage of the ship by American astronauts, the newspaper Kommersant reports. /.../ According to the sources of the publication, the commission, after examining the damages of the ship, came to the conclusion that the hole in the body was made in space, and not at the first attempt, with traces characteristic for work in airless enviroment. At the same time, the source did not rule out the unauthorized penetration of Americans into the Russian ship, the newspaper said. /.../ According to Kommersant, Roskosmos has already requested from NASA copies of videorecorders from the astronauts and their medical records. At the same time the interviewee noted that in case of refusal from cooperation "some additional questions about their involvement in the incident will be superfluous". /.../ Quote Link to comment Share on other sites More sharing options...
