Shadow, a two-month-old grey wolf pup, is seen here playing and rolling around in some ficus twigs that some keepers at California’s San Diego Zoo laid out for him. Shadow’s caretakers are helping to familiarize him with various smells and sights during a 30-day quarantine process. Once Shadow completes the quarantine period, he’ll serve as an animal ambassador during educational presentations. (AP)

NASA’s new atmospheric carbon dioxide monitoring spacecraft called the Orbiting Carbon Observatory-2 or OCO-2 is shown here lifting off aboard a United Launch Alliance Delta II rocket from Space Launch Complex 2 at Vandenberg Air Force Base, California on July 2, 2014. The OCO-2 will measure the global distribution of carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate. (Reuters)

On Jun 28, 2014, after several adverse weather related cancelations, NASA finally got to launch its saucer-shaped Low-Density Supersonic Decelerator (LDSD) test vehicle. The LDSD is shown here being lifted up by a high altitude balloon at the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii. NASA hopes that someday the LDSD will allow the space agency to deploy heavy payloads onto the surface of Mars. (Reuters)

Hugo, a 63-year-old Galapagos Tortoise, is shown here being lured out of his enclosure with a carrot at the Australian Reptile Park near Sydney on July 1, 2014. Hugo had to leave his home for a time so that he could undergo his annual health and weight check. This year he weighed in at 166 kilograms which is one kilogram more than last year. By the way the life expectancy of a Galapagos Tortoise is up to 180 years. (REUTERS)
