NASA has announced that the Kepler Spacecraft has discovered a planet orbiting 1,400 light years away in the constellation Cygnus. The planet, designated Kepler-452b, is 60% wider than earth and has 5 times the Earth’s mass. It orbits its primary every 385 days within the “Goldilocks Zone” and is believed to have an atmosphere and may have oceans and continents.
The New Horizons spacecraft made its closest approach to the planet Pluto today, following a nine year voyage. New Horizons has been sending back a stream of pictures of Pluto and its largest moon, Charon, over the past week and will resume sending out more images over the next couple of months.
Jack King (b.1931) died on June 11. King served as the Kennedy Space Center’s Chief of Public Information from 1960-71 and as NASA’s Public Affairs Officer from 1971-5. During that time, he was the voice of Mission Control, announcing the launch of Apollo 11, among others.
NASA’s Dawn spacecraft entered orbit around Ceres at approximately 7:40 ET on the morning on March 6, the first time a spacecraft has orbited a dwarf planet. Ceres is the largest asteroid and the first discovered, on January 1, 1801. Originally classified as a planet, it was re-classified as an asteroid when it was clear that it was only one of many objects between Mars and Jupiter. Dawn previously orbited Vesta, the second largest asteroid and the fourth discovered, from 2011-2012. This is the first time a spacecraft went into orbit around two objects outside the Earth-Moon system. Dawn will begin its study of Ceres next month and will remain in orbit until 2016.
NASA has found the crash site of Britain’s Beagle 2 Mars probe, which disappeared while attempting to make a soft touchdown on the planet on Christmas Day in 2003. After losing radio contact with the probe, scientists assumed the probe had been destroyed, but the new imagery indicates that it is in one piece.
NASA has announced that astronaut Scott Kelly will spend a year aboard the International Space Station, the longest any American has spent in space at a single time. Kelly has already spent 180 days in space spread out over 2 shuttle missions and a stint on the ISS which was cut short when his sister-in-law Gabrielle Giffords was shot. Kelly will participate in a study of the effects of space travel on twins with his twin brother, Mark Kelly, also an astronaut, who will remain on Earth. Kelly will join an elite club of four cosmonauts who have spent a year or more in space on a single mission.

A possible ammonia leak on the International Space Station caused astronauts to evacuate the American section of the space station. All station personnel successfully made it to the Russian section and the American section was sealed off while a plan to deal with the leak from a cooling system was formulated. Currently there are three Russians, two Americans, and one Italian aboard the station.
Saturday morning’s SpaceX launch of a Falcon 9 to the International Space Station was successful, but the experimental portion of the launch, in which the first stage of the rocket was meant to have a soft landing on a floating barge, was less than successful. The barge landing, which was to pave the way for future soft landings which would allow for the first stage to be reused, was a hard landing. SpaceX CEO Elon Musk stated that the experiment promised more success in the future.
The first flight of Orion, delayed a day, successfully launched, orbited, and splashed down on Friday, December 5. Orion completed two orbits of the Earth, including one at a distance of 3600 miles, more than 15 times higher than the International Space Station orbits. This is the first time a spaceship designed for humans has traveled that far from Earth since the Apollo missions. A little over four hours after launch, Orion splashed down in the Pacific Ocean.
The Philae lander has touched down on Comet 67P/Churyumov-Gerasimenko, marking the first landing on a comet. The Philae was part of the Rosetta mission launched by the European Space Agency. Philae took about seven hours to cross from Rosetta to the comet before it touched down and launched harpoons into the comet’s head to anchor itself. Armed with ten instruments, Philae will help scientists learn more about comets.
