The spacecraft carrying on top the lander capsule, weighed together 1538&nbsp;kg and was 2.7 meters tall. It commenced the main descent, shortly before its [[Impactor (spacecraft)|controlled impact]] it ejected the lander capsule.
The lander had a mass of {{convert|99|kg|lb}} and consisted of a spheroid ''Automatic Lunar Station'' (ALS) capsule measuring {{convert|58|cm|in}}.<ref name="NASA 2023 b332">{{cite web | title=NSSDCA – Spacecraft – Details | website=NASA | date=2023-10-18 | url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1966-006A | access-date=2023-10-19}}</ref> It used a [[Airbag#Spacecraft airbag landing systems|landing bag]] to survive the impact speed of over {{convert|54|km/h|mph}}.<ref>{{cite web|url=http://www.astronautix.com/craft/lunae6.htm|title=Luna E-6|website=astronautix.com|access-date=25 November 2020|url-status=dead|archive-url=https://web.archive.org/web/20160315130827/http://www.astronautix.com/craft/lunae6.htm|archive-date=15 March 2016}}</ref> It was a [[hermetic seal|hermetically sealed]] container with radio equipment, a program timing device, heat control systems, scientific apparatus, power sources, and a television system.

The spacecraft was developed in the design bureau then known as [[OKB-1]], under Chief Designer [[Sergei Korolev]] (who had died before the launch). The first 11 Luna missions were unsuccessful for a variety of reasons. At that time the project was transferred to [[NPO Lavochkin|Lavochkin]] design bureau since OKB-1 was busy with a human expedition to the Moon. ''Luna 9'' was the twelfth attempt at a soft-landing by the Soviet Union; it was also the first successful deep space probe built by the [[NPO Lavochkin|Lavochkin]] design bureau, which ultimately would design and build almost all Soviet (later [[Russia]]n) lunar and interplanetary spacecraft. <ref name="NASA History">{{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|pages=1–2|last1=Siddiqi|first1=Asif A.|lccn=2017059404|isbn=9781626830424|publisher=NASA History Program Office|edition=second |year=2018|id=SP2018-4041|series=The NASA history series|location=Washington, D.C.}}</ref>
