The photos today are from two missions.  First, there are photos of the Mercury-Redstone 3 launch in 1961 and astronaut Alan Shepard; also known as Freedom 7, this suborbital launch was a significant space milestone, carrying the first American into space.  Photo Credits: NASA. 

Second, there is a photo of the InSight Lander launch on ULA Atlas V 401 in 2018 and a photo of the spacecraft being processed. InSight landed on Mars on 11/26/2018.  Photo Credit: NASA.  Here is a caption for the processing photo:

The solar arrays on NASA’s InSight lander are deployed in this test inside a clean room at Lockheed Martin Space Systems, Denver. This configuration is how the spacecraft will look on the surface of Mars. The image was taken on April 30, 2015.

InSight, for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport, is scheduled for launch in March 2016 and landing in September 2016. It will study the deep interior of Mars to advance understanding of the early history of all rocky planets, including Earth. The InSight Project is managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, for the NASA Science Mission Directorate, Washington. InSight is part of NASA’s Discovery Program, which is managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama.  Photo Credit: NASA/JPL-Caltech/Lockheed Martin (public release, found on Wikipedia).

May 5 – A United Launch Alliance Atlas V rocket lifts off from Space Launch Complex 3 at Vandenberg Air Force Base, California, carrying NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, or InSight, Mars lander. Liftoff was at 4:05 a.m. PDT (7:05 a.m. EDT). The spacecraft will be the first mission to look deep beneath the Martian surface. It will study the planet’s interior by measuring its heat output and listen for marsquakes. InSight will use the seismic waves generated by marsquakes to develop a map of the planet’s deep interior. The resulting insight into Mars’ formation will provide a better understanding of how other rocky planets, including Earth, were created. Photo Credit: NASA.
