sh1pman Posted February 26, 2018 Share Posted February 26, 2018 DSG got renamed to LOP-G. Quote Name change aside, there are also some significant LOP-G updates in this budget. First of all, LOP-G has its own line item, with $504 million proposed for 2019 and $2.7 billion total penciled in over the next five years. That means LOP-G is officially happening, and it would take Congressional intervention to stop the program at this point. Quote There’s also some information about LOP-G components, launch dates, and operation plans. Recall that sizewise, LOP-G is a far cry from the ISS. The working design calls for a power and propulsion element (PPE), a habitation element, a logistics element, and an airlock. Some proposed add-ons also include a robotic arm and fancy glass cupola. (Side note: since the LOP-G will probably be positioned in a near-rectilinear halo orbit, a glass cupola would offer incredible, sweeping views of the Moon and Earth together. NASA, I urge you to make that happen!) The PPE isn’t habitable, so astronauts will be confined to just two modules, a visiting Orion spacecraft, and an airlock. The longest crews would stay at the LOP-G in this configuration is a month; NASA might increase that duration if more pieces are added later. https://web.archive.org/web/20180226175759/http://www.planetary.org/blogs/jason-davis/2018/20180226-lop-g-snark-details.html Link to comment Share on other sites More sharing options...

RCgothic Posted February 26, 2018 Share Posted February 26, 2018 It's not hard to add construction capability to a superheavy spacecraft. It takes what, a couple of robot arms and an airlock? Even Orion could do it if they'd given SLS an integral payload bay to carry a dockable construction module. Send one up on Falcon 9 and rendezvous. Job done.

Send one up on Falcon 9 and rendezvous. Job done. Only if you believe Vaporware actually does something other than whip up hype. This doesn't even constitute as hype, NASA has no plan. NASA basically is saying 'we have a whole lot of problems we need to solve before leaving the EM system'. Roughly translated, once they know how to solve the problems, then they we layout their plans to build stuff and then build the infrastructure in space (if they decide to go with fictional fusion) to build such a craft. Right now solar power and light fission reactors are the only viable power source. Even NERVA is off the table because of the need to store liquid hydrogen.

They are large, so unlikely they can replace or add something. Why are these two slackers hanging there? This huge centrifuge would cause the ship rotation in the opposite direction. And as it is far from the CoM, it additionaly would cause a precession. Of course, they can stop the rotation on engines burn (though they didn't), but anyway the long thin ship will be constantly bending due to precession. 8 hours ago, DAL59 said: What the actual heck?
