DART delayed to November launch as environmental testing begins


DART delayed to November launch as environmental testing begins
February 19, 2021
NASA’s Double Asteroid Redirection Test (DART) spacecraft has been moved to its secondary launch window as it begins thermal and environmental testing. The new launch date of November 24, 2021 is a delay from an original target of July 21.
DART is NASA’s first planetary defense demonstration, planned to change an asteroid’s orbit by a kinetic impact. DART is a simple technology demonstrator which will attempt to impact Dimorphos, a moonlet of the asteroid Didymos.
NASA’s Science Mission Directorate (SMD) senior leadership requested a risk assessment to determine the viability of the primary and secondary launch windows. After this assessment was completed, teams determined the primary launch window was no longer viable and the DART team was told to pursue the secondary date.  ....

Nasa delays launch for DART asteroid impact test


Nasa delays launch for DART asteroid impact test
Nasa has chosen a later launch window for testing its first flight demonstration for planetary defence against the threat of asteroid impact.
Dubbed the Double Asteroid Redirection Test (DART), the mission aims to shift an asteroid’s orbit through kinetic impact, in September 2022. Basically, impacting a spacecraft into the smaller member of the binary asteroid system Didymos – classed as a near-Earth potential hazard – to change its orbital speed.
Two launch windows were originally considered: a primary one (July 21, 2021 to August 24, 2021) and a secondary one (November 24, 2021 to February 15, 2022). At the request of Science Mission Directorate (SMD), Nasa says, a risk assessment was performed on the DART project schedule to determine their viability. ....
