DART is scheduled for launch on 22 July 2021. It will head to the binary S-type asteroid system 65803 Didymos, consisting of a primary, Didymos A, roughly 0.8 km in diameter, and a secondary, Didymos B, roughly 160 meters across.


On 31 January 2019, NASA announced that Lucy would launch in October 2021 on an Atlas V 401 rocket from Cape Canaveral, Florida. The total cost for the launch is estimated to be US$148.3 million.

The launch is planned for July 2022 on a Falcon Heavy vehicle. The cost of the launch, including secondary payloads, is $117 million.

Psyche and Janus:
Astronomers created icon-like symbols for the first fifteen asteroids to be discovered, as a type of shorthand notation consistent with older notation for the classical planets. Psyche was given an iconic symbol, as were a few other asteroids discovered after 16 Psyche. The symbol 16 Psyche, a semicircle topped by a star, represents a butterfly's wing, symbol of the soul (psyche is the Greek word for "soul"), and a star.[9]

In ancient Roman religion and myth, Janus (/ˈdʒeɪnəs/ JAY-nəs; Latin: IANVS (Iānus), pronounced [ˈjaːnʊs]) is the god of beginnings, gates, transitions, time, duality, doorways, passages, and endings. He is usually depicted as having two faces, since he looks to the future and to the past.
