This observation from NASA’s Mars Reconnaissance Orbiter show it is late summer in the Southern hemisphere, so the Sun is low in the sky and subtle topography is accentuated in orbital images. via NASA http://ift.tt/2s25Hnd

The SpaceX Falcon 9 rocket, with the Dragon spacecraft onboard, is seen shortly after being raised vertical at Launch Complex 39A at NASA’s Kennedy Space Center in Cape Canaveral, Florida, Thursday, June 1, 2017. Liftoff is scheduled for 5:55 p.m EDT. via NASA http://ift.tt/2sitxbp

Expedition 51 Flight Engineer Thomas Pesquet captured this nighttime photo of Florida from the International Space Station. Bright lights include the Miami-Fort Lauderdale area, and Orlando, with Cape Canaveral to the east, where launch preparations for SpaceX’s next cargo mission are underway at NASA’s Kennedy Space Center. via NASA http://ift.tt/2rkVCyQ

On April 3, 2017, the student-controlled EarthKAM camera aboard the International Space Station captured this photograph of a favorite target — the Grand Canyon — from low Earth orbit. The camera has been aboard the orbiting outpost since the first space station expedition began in November 2000 and supports approximately four missions annually. via NASA http://ift.tt/2r7Hp9U

A new NASA mission, the Neutron Star Interior Composition Explorer (NICER), is headed for the International Space Station to observe one of the strangest observable objects in the universe. In this photo, NICER’s X-ray concentrator optics are inspected for dust and foreign object debris that could impair functionality once in space. via NASA http://ift.tt/2qjUVZp

Astronaut Scott Carpenter walks to the launch site to begin the Mercury-Atlas 7 (MA-7) mission on May 24, 1962. Carpenter’s Aurora 7 capsule lifted off aboard an Atlas rocket from Cape Canaveral, Florida, at 7:45 a.m. EST, May 24. Carpenter was the fourth American in space and second American to orbit Earth. via NASA http://ift.tt/2qQ7tq9

This illustration depicts NASA’s Mars 2020 rover on the surface of Mars. The mission, targeted for launch in July/August 2020, takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. via NASA http://ift.tt/2q7Qktb
