Description
Delta II was an expendable launch system, originally designed and built by McDonnell Douglas. Delta II was part of the Delta rocket family and entered service in 1989. Delta II vehicles included the Delta 6000, and the two later Delta 7000 variants ("Light" and "Heavy"). The rocket flew its final mission ICESat-2 on 15 September 2018, earning the launch vehicle a streak of 100 successful missions in a row, with the last failure being GPS IIR-1 in 1997.

Status: Launch Successful
Mission:
Launch delayed from February 10 and July 30. The Genesis probe flew to the Earth-Sun L1 Lagrangian point and spend two years collecting samples of the solar wind. The collected samples were to be physically returned to Earth in a sample return capsule (air-snatch recovery was planned over Utah) and analysed in ground-based laboratories. On September 8, 2004, the Genesis space probe became the first spacecraft to return from beyond lunar orbit to the Earth's surface. The Genesis Sample Return Capsule separated from the spacecraft on September 8, 66,000 km above the Earth. The capsule successfully re-entered the atmosphere over Oregon at 11 km/s, but a wiring error resulted in the drogue parachute release mortar failing to fire at 33 km altitude. The capsule crashed to earth at 90 m/s in the Dugway Proving Ground at 40 07 40 N 113 30 29 W. Although the vehicle was smashed, some of the samples could be retrieved.

Status: Launch Successful
Mission:
IMAGE (Imager for Magnetopause to Aurora Global Exploration) uses neutral atom, ultraviolet, and radio imaging techniques to identify the dominant mechanisms for injecting plasma into the magnetosphere on substorm and magnetic storm time scales, determine the directly driven response of the magnetosphere to solar wind changes; and, discover how and where magnetospheric plasmas are energized, transported, and subsequently lost during substorms and magnetic storms.
