The photos today are from two events.  

The first event includes the successful launch of Mars Reconnaissance Orbiter (MRO) by Atlas V 401 in 2005, a photo of MRO during assembly operations and an example of the high resolution photograph from MRO; MRO is still operating in orbit of Mars.  Photo Credits: NASA; NASA/KSC (high gain antenna installation on MRO); NASA/JPL-Caltech/University of Arizona (MRO high resolution photograph).  Here is the caption for the MRO photograph of MARS:

This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter shows a location on Mars associated with the best-selling novel and Hollywood movie, “The Martian.”

This area is in the Acidalia Planitia region. In the novel and the movie, it is the landing site of a crewed mission named Ares 3. For the story’s central character, Acidalia Planitia is within driving distance from where NASA’s Mars Pathfinder, with its Sojourner rover, landed in 1997.

An initial HiRISE image of the site was taken in April 2015 and is online  [link removed so photos can be shared]. A second one was taken May 17, 2015, and is shown here.

The second event has a photo of the launch of the Parker Solar Probe on Delta 4H in 2018. Photo Credit: NASA/Bill Ingalls.

August 12 – The United Launch Alliance Delta IV Heavy rocket launches NASA’s Parker Solar Probe to touch the Sun, Sunday, Aug. 12, 2018 from Launch Complex 37 at Cape Canaveral Air Force Station, Florida. Parker Solar Probe is humanity’s first-ever mission into a part of the Sun’s atmosphere called the corona. Here it will directly explore solar processes that are key to understanding and forecasting space weather events that can impact life on Earth. Photo Credit: (NASA/Bill Ingalls)
