The circumstellar disk around the young star HR 4796A, as imaged by the Gemini Planet Imager, which is mounted on the 8.2-m Gemini South telescope in Chile. These images reveal a complex pattern of variations in brightness and polarization around the HR 4796A disk. The western side (tilted closer to the Earth) appears brighter in polarized light, while in total intensity the eastern side appears slightly brighter, particularly just to the east of the widest apparent separation points of the disk.

The field of exoplanetary research has seen a tremendous growth during the last decade, with the launch of space-based planet-hunting telescopes like the joint ESA/French Space Agency CoRoT and NASA’s Kepler telescopes, which have turned the discovery of new exoplanets around other stars from a historic occasion into a more or less routine procedure, as evidenced by the impressive tally of more than a thousand extrasolar worlds that have been confirmed by Kepler alone, as well as the thousands more that are still awaiting confirmation. Not to be outdone, a number of next-generation ground-based instruments that have also come on-line during the last couple of years promise to usher in a new era in exoplanetary science as well, allowing for the more detailed observation and characterisation of exoplanets around other stars through advanced direct imaging techniques. One such instrument, the Gemini Planet Imager, which is mounted on the 8.1-m Gemini South telescope in Cerro Pachón, Chile, has recently completed a year-long test and commissioning period, while capturing the images and spectra of previously discovered exoplanetary systems in unprecedented detail along the way, which are challenging several theoretical predictions regarding planetary formation.

BALLY, PA, and KENNEDY SPACE CENTER, FL — What did NASA and Orion prime contractor Lockheed Martin learn from the maiden test flight of the agency’s next generation crew vehicle, following its recent successful launch in December 2014 and homecoming return to the Kennedy Space Center?
“Orion is in incredible shape!” NASA Administrator Charles Bolden told AmericaSpace during an interview at Bally Ribbon Mills in Bally, Penn., on Jan. 9. “It gives a lot of confidence [for the future].”

The first full week of the new year was busy on the International Space Station (ISS), aside from Wednesday, when the entire Expedition 42 crew was given a much-deserved day off in observance of the Russian Christmas holiday. As the crew waited for the SpaceX Falcon 9 to launch with their CRS-5 Dragon capsule full of goodies, work continued for ongoing science experiments and research.

Two days after departing Space Launch Complex (SLC)-40 at Cape Canaveral Air Force Station, in a blazing light show, SpaceX has successfully delivered its fifth dedicated Dragon cargo mission (CRS-5) to the International Space Station (ISS). Capture of the spacecraft by Expedition 42 Commander Barry “Butch” Wilmore and Flight Engineer Samantha Cristoforetti took place at 5:54 a.m. EST Monday, 12 January, as Dragon and the station flew high above the Mediterranean, just to the southeast of Barcelona. The progress of this latest visitor to the ISS had gone so smoothly that the capture occurred a full 18 minutes ahead of schedule, prompting Capcom Randy Bresnik in the Mission Control Center (MCC) at the Johnson Space Center (JSC) in Houston, Texas, to jokingly advise Wilmore: “Not bad … for a Navy guy!” Exactly three hours after the initial grapple of the spacecraft, a perfect berthing at the Earth-facing (or “nadir”) port of the Harmony node was completed and Dragon is now a part of the ISS until 10 February.

In the early morning hours of Saturday, Jan. 10, 2015, SpaceX kicked off the United States’ busy 2015 space launch manifest with their fifth NASA-contracted Dragon resupply flight to the International Space Station (ISS). Onboard the $100 billion orbiting science research outpost is over 5,000 pounds of supplies, cargo, and experiments for the Expedition 42 crew (and later Expedition 43), including critical materials to support 256 science and research investigations, and the AmericaSpace imagery team set out to capture some up-close views of the launch.

Nineteen years ago, today, on 11 January 1996, Shuttle Endeavour and a six-man crew—Commander Brian Duffy, Pilot Brent Jett, and Mission Specialists Leroy Chiao, Winston Scott, Dan Barry, and Japanese astronaut Koichi Wakata—rocketed into orbit in pursuit of Japan’s Space Flyer Unit (SFU). Launched 10 months earlier, the octagonal satellite carried a mixture of biological, technological, and astronomical experiments, and it was the task of STS-72 to recover it from orbit and bring it back to Earth. Additionally, as described in yesterday’s AmericaSpace history article, the crew was expected to deploy and retrieve another satellite, support several experiments, and perform two EVAs to support critical hardware tests for the International Space Station (ISS).

There is a report about Mars which has been getting a lot of attention the past few weeks (in addition to the methane and organics found): that the Curiosity rover may have found evidence for ancient microbial life itself. Specifically, microbial mats, which are common on Earth; the report comes from noted geobiologist Nora Noffke, who has been studying images sent back by the rover since it landed in 2012.

The new year has kicked off nicely for NASA thus far, not just because of a successful fifth SpaceX Dragon resupply launch to the International Space Station (ISS), but also because the agency’s Stennis Space Center near Bay St. Louis, Miss., has ushered in a new era with the first static test fire of a development engine for the Space Launch System (SLS), NASA’s massive rocket which will launch astronauts on missions of exploration farther into space than any humans have ever been, starting next decade.

Almost two decades ago, six astronauts rocketed into the night on a mission which put virtually all of the shuttle’s capabilities—satellite deployment and retrieval, rendezvous and proximity operations, research, and spacewalking—to the test, as well as providing a great insight into the work that NASA would require to build the International Space Station (ISS). STS-72, launched aboard Endeavour on 11 January 1996, was tasked with capturing a Japanese spacecraft, after 10 months in orbit, as well as deploying and retrieving a small free-flying satellite and evaluating tools for ISS assembly and maintenance.

The ground of Cape Canaveral Air Force Station, Fla., shook under 1.3 million pounds (590,000 kg) of thrust this morning (Saturday, 10 January), as SpaceX’s Falcon 9 v1.1 booster—laden with the fifth dedicated Dragon cargo mission (CRS-5) to the International Space Station (ISS)—roared away from Space Launch Complex (SLC)-40 precisely at 4:47:10 a.m. EST. It was notable that the company which last September won contracts to possibly launch the first U.S. astronauts from U.S. soil since the end of the shuttle era has now achieved the first launch of a U.S. vehicle from U.S. soil in 2015. At the time that this article was being prepared, the Dragon spacecraft had successfully separated from the second stage of the booster and had successfully deployed its electricity-generating solar arrays, its Guidance and Navigation Control (GNC) Bay Door, and critical rendezvous sensors, ahead of a scheduled capture and berthing at the space station by Expedition 42 Commander Barry “Butch” Wilmore and Flight Engineer Samantha Cristoforetti on Monday morning.
