stage with the lander. Twin Lander JPL also built a full-scale engineering model, named ForeSight. This was used to practice instrument deployment, trial new ways to deploy the HP3 instrument, and test methods to reduce seismometer noise. With the mission now ended, the testbed is being scrapped and its parts will be offered to other teams like the Mars Sample Retrieval Lander (SRL) for the Mars Sample Return campaign at JPL to be repurposed for their own needs. SRL currently looks to have a similar design, but with different domed-shaped deck and five solar panels instead of two on InSight and ForeSight. Anything that is not needed will go into storage. But there no attempt will be undertaken to restore ForeSight or send it to a Museum. Journey to Mars Launch On 28 February 2018, InSight was shipped via C-17 cargo aircraft from the Lockheed Martin Space building in Denver to Vandenberg Air Force Base in California in order to be integrated to the launch vehicle. The lander was launched on 5 May 2018 and arrived on Mars at approximately 19:54 UTC on 26 November 2018. The spacecraft was launched on 5 May 2018 at 11:05 UTC on an Atlas V 401 launch vehicle (AV-078) from Vandenberg Air Force Base Space Launch Complex 3-East. This was the first American interplanetary mission to launch from California. The launch was managed by NASA's Launch Services Program. InSight was originally scheduled for launch on 4 March 2016 on an Atlas V 401 (4 meter fairing/zero (0) solid rocket boosters/single (1) engine Centaur) from Vandenberg Air Force Base in California, U.S., but was called off in December 2015 due to a vacuum leak on the SEIS instrument. The rescheduled launch window ran from 5 May to 8 June 2018. Major components of the launch vehicle include: Common Core Booster This launch did not use additional solid rocket boosters Centaur with Relay CubeSats InSight in a Payload fairing The journey to Mars took 6.5 months across for a touchdown on 26 November. After a successful landing, a three-month-long deployment phase commenced as part of its two-year (a little more than one Martian year) prime mission. Cruise After its launch from Earth on 5 May in 2018, it coasted through interplanetary space for 6.5 months traveling across for a touchdown on 26 November in that year. InSight cruise stage departed Earth at a speed of .
