How Deep Space 1 connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
Periodic comet — 19P/Borrelly.
A spacecraft that passes a small body once at high speed, gathering images and data during a brief encounter. Flybys are the cheapest way to reach a new target — Giotto at Halley, Deep Space 1 at Borrelly, Lucy at the Trojans.
A highly reliable medium-lift workhorse that launched GPS satellites and many NASA planetary missions, including the Mars rovers Spirit and Opportunity and the Kepler telescope.
The Jet Propulsion Laboratory is a NASA federally funded research and development center in California that builds and operates robotic spacecraft.
Onboard software that processes optical-navigation images in real time and steers the spacecraft itself, without waiting for commands from Earth. It was pioneered by Deep Space 1 and used for terminal guidance in fast flybys and the DART impact.
A NASA mission at the Sun–Earth L1 point that measures the solar wind and energetic particles upstream of Earth, giving roughly an hour of warning before disturbances reach the planet.
ESA's Asteroid Impact Mission — the original European orbiter half of the AIDA collaboration, meant to observe the DART impact in real time. It was not funded in 2016, but its science was largely revived and reshaped as the Hera mission.
Apollo 11 was the NASA mission that in July 1969 first landed humans on the Moon, with Neil Armstrong and Buzz Aldrin walking on the lunar surface.
Apollo 13's planned lunar landing was aborted after an oxygen-tank explosion; the crew returned safely in a celebrated rescue.
Apollo 17 was the final crewed Apollo lunar landing, carrying the first scientist-astronaut to the Moon.
Apollo 8 was the first crewed mission to leave Earth orbit and orbit the Moon, returning the famous 'Earthrise' photograph.
