| 11 | + | ||
| 12 | +ESA's first deep space mission, Giotto was designed to help solve the mysteries | ||
| 13 | +surrounding Comet Halley by passing as close as possible to the comet's nucleus, | ||
| 14 | +which it achieved on 14 March 1986 at a distance of just under 600 km. No-one | ||
| 15 | +expected the spacecraft to survive its battering from comet dust during this encounter, | ||
| 16 | +but although Giotto was damaged during the flyby, most of its instruments remained operational. | ||
| 17 | +The mission was extended to allow a additional encounter with comet Grigg-Skjellerup on 10 July 1992, at a | ||
| 18 | +distance of around 200 km. | ||

| 10 | - <Description>International Cometary Explorer : Giacobini-Zinner Flyby</Description> | 10 | + <Description>The International Cometary Explorer (ICE) spacecraft (designed and launched as the |
| 11 | + International Sun/Earth Explorer 3 (ISEE-3) satellite), was launched August 12, 1978, | ||
| 12 | + into a heliocentric orbit. It was one of three spacecraft, along with the mother/daughter pair | ||
| 13 | + of ISEE-1 and ISEE-2, built for the International Sun-Earth Explorer (ISEE) program, a | ||
| 14 | + joint effort by NASA and ESRO/ESA to study the interaction between the Earth's magnetic field | ||
| 15 | + and the solar wind. | ||
| 16 | + | ||
| 17 | +ISEE-3 was the first spacecraft to be placed in a halo orbit at the L1 Earth-Sun Lagrangian point. | ||
| 18 | +Renamed ICE, it became the first spacecraft to visit a comet, passing through the tail of Comet Giacobini-Zinner | ||
| 19 | +within about 7,800 km of the nucleus. NASA suspended routine contact with ISEE-3 in 1997, and made brief status | ||
| 20 | +checks in 1999 and 2008. | ||
| 21 | + | ||
| 22 | +On May 29, 2014, two-way communication with the spacecraft was reestablished by the ISEE-3 Reboot Project, | ||
| 23 | +an unofficial group[4] with support from the Skycorp company. On July 2, 2014, they fired the thrusters for the | ||
| 24 | +first time since 1987. However, later firings of the thrusters failed, apparently due to a lack of nitrogen | ||
| 25 | +pressurant in the fuel tanks.[8][9] The project team will pursue an alternative plan to use the spacecraft to | ||
| 26 | +"collect scientific data and send it back to Earth.</Description> | ||
