Double Asteroid Redirection Test (DART) mission is the first-ever mission to demonstrate the capability to deflect an asteroid by colliding a spacecraft with it at high speed, a technique known as a kinetic impactor. DART is a planetary defense-driven test of one of the technologies for preventing the Earth impact of a hazardous asteroid: the kinetic impactor. DART's primary objective is to demonstrate a kinetic impact on a small asteroid. The binary near-Earth asteroid (65803) Didymos is the target for DART. While Didymos' primary body is approximately 800 meters across, its secondary body has a 150-meter size, which is more typical of the size of asteroids that could pose a more common hazard to Earth. The DART spacecraft will achieve the kinetic impact by deliberately crashing itself into the moonlet at a speed of approximately 6 km/s, with the aid of an onboard camera and sophisticated autonomous navigation software. The collision will change the speed of the moonlet in its orbit around the main body by a fraction of one percent, enough to be measured using telescopes on Earth.Heliocentric N/A B1063 - Flight Proven ( ) Of Course I Still Love You
The Sentinel-6 Michael Freilich and Sentinel-6B make up the Sentinel-6 mission, also known as Jason Continuity of Service (Jason-CS), which is a partnership between NASA, NOAA, ESA, and EUMETSAT. This mission continues the long-term global sea surface height data record begun by first Jason satellites in 1992. Named after former NASA Earth Science Division Director Michael Freilich, Sentinel-6 Michail Freilich will provide altimeter data necessary for ocean climate monitoring, ocean modelling and numerical ocean prediction, weather forecasting, marine meteorology, coastal altimetry and modelling. A secondary objective of the mission is to collect high-resolution vertical profiles of temperature, using the Global Navigation Satellite System (GNSS) Radio-Occultation sounding technique, to assess temperature changes in the troposphere and stratosphere and to support numerical weather prediction. Sentinel-6 Michael Freilich is to operate in a highly-inclined circular orbit at an altitude of 1336 km, with an operational mission lasting 5 years. Near-identical Sentinel-6B is planned to follow-up shortly after.Low Earth Orbit #SeeingTheSeas B1063 - Maiden Flight Landing Zone 4
