'''''Deep Space 1''''' ('''DS1''') was a [[NASA]] technology demonstration [[spacecraft]] which flew by an [[asteroid]] and a [[comet]]. It was part of the [[New Millennium Program]], dedicated to testing advanced technologies.

Launched on 24 October 1998, the ''Deep Space 1'' spacecraft carried out a flyby of asteroid [[9969 Braille]], which was its primary science target. The mission was extended twice to include an encounter with comet [[19P/Borrelly]] and further engineering testing. Problems during its initial stages and with its star tracker led to repeated changes in mission configuration. While the flyby of the asteroid was only a partial success, the encounter with the comet retrieved valuable information.

The Deep Space series was continued by the ''[[Deep Space 2]]'' probes, which were launched in January 1999 piggybacked on the [[Mars Polar Lander]] and were intended to strike the surface of Mars (though contact was lost and the mission failed). ''Deep Space 1'' was the first NASA spacecraft to use [[ion thruster|ion propulsion]] rather than the traditional chemical-powered rockets.<ref>{{cite book |url=https://www.nasa.gov/sites/default/files/atoms/files/beyond-earth-tagged.pdf |archive-url=https://web.archive.org/web/20190424211923/https://www.nasa.gov/sites/default/files/atoms/files/beyond-earth-tagged.pdf |archive-date=2019-04-24 |url-status=live |title=Beyond Earth: A Chronicle of Deep Space Exploration, 1958–2016 |series=NASA History Series |publisher=NASA |last=Siddiqi |first=Asif A. |edition=2nd |page=2 |year=2018 |id=SP-2018-4041 |lccn=2017059404 |isbn=978-1-62683-042-4}}</ref>
