KENNEDY SPACE CENTER, FLA. -- An adult Black-necked Stilt keeps a wary eye out for intruders. The species inhabits salt marshes and shallow coastal bays in the East, as well as freshwater marshes in the West. They are found along the Atlantic Coast from Delaware to northern South America. The black and white markings, long red legs and straight, very thin bill make the stilt very recognizable. This stilt was photographed in the Merritt Island National Wildlife Refuge, which shares a boundary with Kennedy Space Center. The Refuge encompasses 92,000 acres that are a habitat for more than 331 species of birds, 31 mammals, 117 fishes, and 65 amphibians and reptiles. The marshes and open water of the refuge provide wintering areas for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, great egrets, wood storks, cormorants, brown pelicans and other species of marsh and shore birds, as well as a variety of insects

Upgrades to the surface of pad B, as well as the systems below and surrounding the pad will support the new processing and launch requirements for NASA's Space Launch System (SLS) and the Orion spacecraft for deep-space missions, including the journey to Mars. The modifications and improvements to processing and launch facilities will support Kennedy as a multi-user spaceport for government and commercial launches for years to come. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to Pad 39B.

The crew, first ever to launch on Independence Day, tested new equipment and procedures to improve shuttle safety, as well as delivered supplies and made repairs to the space station.

STS-56 Earth observation taken aboard Discovery, Orbiter Vehicle (OV) 103, is of the Strait of Gibraltar. A small bank of clouds marks the passage between Spain and Morocco at the western edge of the Mediterranean Sea. This passage, one of the two Pilars of Hercules of the Ancient Greeks, is now known as the Strait of Gibraltar. The cities of Cadiz on the Atlantic Coast of Spain and Malaga on the Mediterranean coast, as well as Tangier, Morocco (facing the strait), can be seen. According to NASA scientists studying the STS-56 photos, a subtle difference in the water color on the Atlantic side suggests that a pulse of surface water had recently flowed out of the Mediterranean into the Atlantic.

STS109-322-028 (6 March 2002) --- Astronaut Richard M. Linnehan, STS-109 mission specialist, participates in the third of five space walks to perform work on the Hubble Space Telescope (HST). Linnehan's sun shield reflects astronaut John M. Grunsfeld and the blue and white Earth's hemisphere as well as one of the telescope's new solar arrays. The third overall STS-109 extravehicular activity (EVA) marked the second of three for Linnehan and Grunsfeld, payload commander. On this particular walk, the two turned off the telescope in order to replace the power control unit or PCU--the heart of its power system. Grunsfeld took this photo with a 35mm camera.

NASA's Curiosity Mars rover used a new drill method to produce a hole on Feb. 26, 2018, in a target named Lake Orcadie. The hole marks the first operation of the rover's drill since a motor problem began acting up more than a year ago. An early test produced a hole about a half-inch (1-centimeter) deep at Lake Orcadie --- not enough for a full scientific sample, but enough to validate that the new method works mechanically. This was just the first in what will be a series of tests to determine how well the new drill method can collect samples. A video is available at https://photojournal.jpl.nasa.gov/catalog/PIA22224
