Například takhle vypadá raketovej stupeň systému Bloostar španělské společnosti zero2infinity. Jedná se o třístupňovou toroidní raketu, kde 1. stupeň je vnější prstenec, 2. prostřední a 3. střed.

CLUMP: " The patent does say that the elevator could be scaled to reach 200km, but that's a little like saying that your bank balance could be scaled to reach $1 billion—it's technically true, but the execution may prove tricky."

Před nedávnem jsem tu vyhrožoval nepříjemnými "naposled" v rámci mise:
Za tři dny proběhne historicky poslední průlet Cassini kolem měsíce Dione
17.8. ve 20:30 SELČ mine sonda povrch měsíce ve vzdálenosti 474 km.

BOULDER FLYING BY COMET
This sequence of images, taken with Rosetta’s OSIRIS narrow-angle camera on 30 July 2015,
show a boulder-sized object close to the nucleus of Comet 67P/Churyumov–Gerasimenko.
The images were captured on 30 July 2015, about 185 km from the comet. The object measures
between one and 50 m across; however, the exact size cannot be determined as it depends on
its distance to the spacecraft, which cannot be inferred from these images.

New: Interactive viewer for comet 67P/C-G | Rosetta - ESA's comet chaser
http://blogs.esa.int/rosetta/2015/08/13/new-interactive-viewer-for-comet-67pc-g/

In the week that we celebrate a year that Rosetta has been at Comet 67P/Churyumov-Gerasimenko and mark their passage through perihelion, we are delighted to present a new interactive tool that allows you to explore the shape and surface of this intriguing comet.

In the approach to perihelion over the past few weeks, Rosetta has been witnessing growing activity from Comet 67P/Churyumov–Gerasimenko, with one dramatic outburst event proving so powerful that it even pushed away the incoming solar wind.

The comet reaches perihelion on Thursday, the moment in its 6.5-year orbit when it is closest to the Sun. In recent months, the increasing solar energy has been warming the comet’s frozen ices, turning them to gas, which pours out into space, dragging dust along with it.
