The Cassini spacecraft is close enough to Saturn to observe unusual transitory “clumps” in the planet’s ring system. First spotted by the Voyager space probes in the early 1980s, these clumps zip around Saturn’s outermost rings, following the direction of the planet’s own motion, but until now it hasn’t been possible to get close enough to study those clumps. Unlike the Voyagers, however, Cassini won’t be zipping past the planet at the speed of a bullet – it will enter an orbit around the planet in July and keep an eye on things.

After a five-month design study focusing on alternatives to a winged (and manned) reusable first stage bosoter for the upcoming Space Shuttle, NASA settles on a configuration consisting of two solid rocket boosters strapped to the shuttle’s external fuel tank. Among the alternatives considered was the possibility of restarting production of the Saturn V rockets that launched Apollo and Skylab missions, with the shuttle and its fuel tank separating from the Saturn V’s first stage at high altitude (though in this configuration, a failure of the shuttle’s main engines would prove to be catastrophic). The SRB/tank configuration is expected to shave half a billion dollars off of the shuttle’s development costs.
