Previous missions to Jupiter have included only brief flybys of its moons because to slow down and go
into orbit using conventional trajectories takes "a colossal amount of fuel," Marsden says.
Navigating celestial currents: math leads spacecraft on joy rides through the solar system
Interorbital has designed a space capsule called Neptune that will blast off from a platform in the ocean and then soar
into orbit around Earth.
Spaced out! A high-tech race could make space tourism more affordable
It succeeded only too well, and a stunned United States replied with a stunt of its own, firing Explorer-1
into orbit and beginning the space race in earnest.
Beyond Columbia: is there a future for humanity in space?
It launched Sputnik, the first artificial satellite,
into orbit around the Earth.
THE SPACE RACE
In the absence of the chemical, natural and artificial recycling processes used on Earth, objects senc t
into orbit become fossil-projectiles.
Garbage in orbit: debris from 40 years of space exploration presents a thorny disposal problem
The Sun pulls the craft
into orbit, and this orbit carries it on its journey--just as the Earth orbits the Sun.
Fantastic journey
An electric field will accelerate the ions to high velocity as they shoot out of the rear of the craft, enabling the craft to slip
into orbit about Mercury rather than spiral into the sun.
Forgotten Planet
The use of small and intermediate-sized satellites could reduce costs, get instruments
into orbit earlier and allow greater resiliency in case problems arise, says panel chairman Edward Frieman, director of the Scripps Institution of Oceanography in La Jolla, Calif.
NASA inches toward smaller satellites
An unexpected event occurred when Magellan jettisoned the solid-propellant rocket motor that had put it
into orbit. Spear says the jolt apparently caused one set of gyros in Magellan's positioning system to switch off and another set to take over.
Radar-mapper Magellan orbits Venus
Hiten's primary objective is simply to try out the technique ISAS has chosen to put satellites into lunar orbit: having one spacecraft come close enough to the moon for the lunar gravity to capture a second craft
into orbit. Project scientist Kuninori Uesugi says ISAS hopes Hiten will complete eight visits near the moon during the mission's planned one-year lifetime.
From the earth to the moon with love: Japan translates its lunar fascination into a scientific mission
But when post-Challenger flight delays left NASA short of available shuttle space, project scientists redesigned the satellite so that it could ride a Delta 2 rocket
into orbit. Rather than travel into "deep space," this X-ray observatory will orbit Earth while scanning emissions from our galaxy and beyond.
Space 1990: launching a new decade of exploration
The satellite carried four incandescent bulbs
into orbit, and these are essential to the imaging system.
Weather satellite GOES blind
But although the satellite went
into orbit in 1980, the continuous stream of data from some of its instruments goes back only to the repair mission (SN: 4/14/84, p.228), leaving seven years remaining.
Back to the Max: the salvation option
Solar Max went
into orbit in 1980, and although it did detect one of the Air Force craft's six comets, it failed until recently to find any sun-grazers of its own.
Sun-grazers: a hot road to the end
The telescope is just now nearing completion, and before the Challenger explosion sent NASA's plans into disarray, it was scheduled to go
into orbit later this year.
