Cargo down mass?
WALLOPS ISLAND, Va. -- A successful NASA flight test Monday demonstrated how a spacecraft returning to Earth can use an inflatable heat shield to slow and protect itself as it enters the atmosphere at hypersonic speeds. Shouldn't Arthur C Clarke's family get royalties on this ? He had that concept demonstrated in 2010 with aerobraking around jupiter :-) :-) NASA is going to have to be a but more specific about the material used for the balloon. If this to be of any serious use for manned flights, it needs to sustain thousands of degrees of heat for what ? 15 minutes ? I guess this could be of use for non-orbital launches that go high up, and straight down (for instance, weather instruments). |

NASA is doing cutting edge research routinely. It just doesn't show up here for discussion much because it's not always the big sexy stuff. That and they're not doing anything very big anymore. Most of the money gets eaten up by the manned spaceflight budget. NASA has yet to fly a liquid fueled axial or linear aerospike engine on a flight profile similar to a launch vehicle's first stage (which is where you'd use such an engine). The linear aerospike engines from X-33 were only tested on the ground. The data which really needs to be gathered would be at altitude (from sea level to vacuum). The best I've seen so far is sounding rocket data which used a solid stage and compared a conventional nozzle to an axial aerospike nozzle. Unfortunately, the data wasn't very good (likely due to erosion of the nozzles by the solid exhaust), so no real conclusions could be made.

Yes, REAL suspected Black Holes can RiP you APART.!! But NOT in GR gtr Tivity.!! Because in GR Tivity you would be a POiNT ..and if you COULD have a mass, in GR, you would be a POiNT-mass.
