“It’s great to have the opportunity to participate in the space program,” astronaut Eric Boe told an interviewer on the eve of STS-133, the final flight of Shuttle Discovery, in February 2011. “It hasn’t been that many years ago that we walked on the Moon and, here we are with a fully completed space station. There’s many exciting things happen in space and we’re looking forward to exploration that we know is going to happen in the future, going back to the Moon and on to Mars and on to a lot of other different bodies out in the galaxy and on into the Universe.” And for Boe, who turns 50 today (Wednesday, 1 October) and has been for the past two years Deputy Chief of the Astronaut Office, he has a front-row seat and a very personal involvement in the post-shuttle transition toward what might be labeled “The Exploration Era,” as NASA moves toward Commercial Crew and its first missions beyond low-Earth orbit in almost five decades.

The team leading the European Space Agency’s (ESA) Rosetta mission has chosen Nov. 12 as the date to deploy the piggybacked Philae lander for mankind’s history-making first attempt to touchdown on the surface of a comet.
The “head” of the bizarre comet 67P/Churyumov-Gerasimenko had already been selected as the primary landing site for Philae, at a target known as “Site J,” which is located on the smaller of the two “lobes.” See location in image above.

KENNEDY SPACE CENTER — Sierra Nevada Corporation (SNC) will “continue developing the Dream Chaser” space plane despite losing out on this month’s high-stakes contract award for NASA’s commercial “space taxi” program to carry astronauts to the International Space Station (ISS) and the significant company workforce layoffs announced as an inevitable result of the contract loss, SNC representatives told AmericaSpace.

The mystery of an unusual feature in one of Titan’s hydrocarbon seas, dubbed the “mystery island,” has taken an interesting turn. After apparently disappearing following its initial discovery in 2013, it has now reappeared and has changed in appearance and size, as well.

Five hundred years after the 1506 death of navigator and explorer Christopher Columbus, in the summer of 2006, a multi-national team of astronauts were appointed to shuttle mission STS-122, which would transport his spacefaring namesake—the European Space Agency’s (ESA) Columbus laboratory module—into low-Earth orbit and its permanent berth at the International Space Station (ISS). Named to command STS-122 was another navigator and explorer, Stephen Nathaniel Frick, a veteran shuttle pilot who today (Tuesday, 30 September) celebrates his 50th birthday and has helped to chart NASA’s next steps into deep space through his position as chief of the Astronaut Office Exploration Branch.

“Drill, Baby, Drill” has replaced “Drive, Drive, Drive” as the Curiosity Mars rover team’s new mantra, ever since the six-wheeled behemoth pulled up to the foothills of Mount Sharp to begin the systematic layer-by-layer investigation of the humongous mountain that was envisioned years ago when it was selected as the landing site on the Red Planet.

Sunny and hot all year-round, with no clouds on the horizon … That’s not a weather forecast only for the Maldive Islands here on Earth, but also for exoplanet HAT-P-11b, according to the latest findings by an international team of astronomers. But don’t start packing for that holiday package just yet, for HAT-P-11b is a steamy Neptune-sized world located so close to its host star that average temperatures there reach a scortching 1,120 degrees Fahrenheit.

Twenty years ago, on 30 September 1994, the crew of Shuttle Endeavour rocketed into orbit—six weeks later than originally planned—on an 11-day mission to support the second Space Radar Laboratory (SRL-2). As described in yesterday’s AmericaSpace history article, the mission, STS-68, featured the Shuttle Imaging Radar (SIR-C) and the X-band Synthetic Aperture Radar (X-SAR) and sought to perform radar imaging of most of Earth’s surface. Following on from SRL-1, which had flown earlier in the year, it was hoped that SRL-2 would allow surface changes to be monitored between the spring and the fall. However, STS-68 fell foul to the shuttle program’s last Redundant Set Launch Sequencer (RSLS) abort, a harrowing on-the-pad shutdown of Endeavour’s three main engines … just 1.9 seconds before the scheduled liftoff on 18 August.

Last August the U.S. Air Force Space and Missile Systems Center issued a Booster Propulsion and Launch System Request for Information (or RFI) for development of a new engine to replace the controversial Russian-made RD-180 engines that currently power ULA’s workhorse Atlas-V rockets, and this week ATK announced their proposal of an American-made commercial solid rocket alternative to the liquid-fueled RD-180 for the Air Force’s consideration.
