NASA InSight Mission to Mars Arrives at Launch Site
NASA's InSight spacecraft has arrived at Vandenberg Air Force Base in central California to begin final preparations for a launch this May.
NASA's InSight spacecraft
has arrived at Vandenberg Air Force Base in central California to begin final
preparations for a launch this May. The spacecraft was shipped from Lockheed
Martin Space, Denver, today and arrived at Vandenberg at 3:49 p.m. PST (6:49
p.m. EST). The launch period for InSight opens May 5 and continues through June
8. InSight will be the first mission to look deep beneath the Martian surface,
studying the planet's interior by listening for marsquakes and measuring the
planet's heat output. It will also be the first planetary spacecraft to launch
from the West Coast."The Air Force C-17 crew from the 21st Airlift Squadron gave us a great
ride," said Tom Hoffman, InSight project manager, from NASA's Jet
Propulsion Laboratory in Pasadena, California. "Next time InSight travels as
high and as fast, it will be about 23 seconds into its launch, on the way to
Mars."At the Astrotech
payload processing facility at Vandenberg, InSight will soon be removed from
its shipping container -- the first of several remaining milestones to prepare
it for launch. Later next week, the spacecraft will begin functional testing to
verify its state of health after the flight from Colorado. After that, the team
will load updated flight software and perform a series of mission readiness
tests. These tests involve the entire spacecraft flight system, the associated
science instruments and the ground data system.NASA's InSight spacecraft arrived at Vandenberg Air Force Base, California, to begin final preparations for launch.

It will be the first planetary spacecraft to launch from this west coast launch facility.  The launch period for InSight opens May 5, 2018 and continues through June 8, 2018."One
of the most important activities before launch is to load the spacecraft with
the fuel needed for the journey to Mars," said Hoffman. "After fuel
loading, the spacecraft will undergo a spin-balance test to determine precisely
the center of mass. This knowledge is needed to be sure the entry and descent
into the Mars atmosphere goes as planned."InSight will be carried into space aboard a United Launch Alliance Atlas V-401
rocket lifting off from Space Launch Complex 3E at Vandenberg Air Force Base. For
a May 5 liftoff, the launch window opens at 4:05 a.m. PDT (7:05 a.m. EDT) and
remains open through 6:05 a.m. PDT (9:05 a.m. EDT).InSight
will use the seismic waves generated by marsquakes to map the deep interior of
Mars. These waves travel through geologic materials at different speeds and
reflect off boundaries, giving scientists a glimpse of the composition and
structure of the planet's interior. They reflect the initial formation of the
planet, and the resulting insights into how Mars formed will help us better
understand how other rocky planets are created, including our own Earth.JPL manages InSight for NASA's Science Mission Directorate.
InSight is part of NASA's Discovery Program, managed by the agency's Marshall
Space Flight Center in Huntsville, Alabama. The InSight spacecraft, including
cruise stage and lander, was built and tested by Lockheed Martin Space in
Denver. A
number of European partners, includingFrance's
Centre National d'Études Spatiales (CNES) and the German Aerospace Center (DLR), are
supporting the InSight mission.For
