Thirty years ago, this week, one of the most significant Space Shuttle science missions ever undertaken hung—for the merest of minutes—in the balance, suspended on a knife-edge of success and failure, some 67 miles (108 km) above Earth. Heading towards low-Earth orbit at more than 9,300 mph (15,000 km/h) on the afternoon of 29 July 1985, Challenger was in the process of delivering her eighth human crew on the Spacelab-2 mission to explore the Sun and the cosmos in unprecedented detail, using a battery of telescopes and instruments in her payload bay. Three weeks earlier, on 12 July, the crew of Mission 51F had also suffered a hairy shutdown of their three main engines on the pad, seconds before liftoff. If the crew believed to have weathered their run of bad luck, they could not have been more mistaken. Today, with the shuttle now a figure of history, Mission 51F stands alone as arguably the most significant near-miss in the program’s 30-year operational lifespan.

For anyone wishing to place a safe bet, one could look no further than the exciting discoveries of planetary exploration. Every time a spacecraft is sent to a planetary destination for the first time, previously unimagined and fascinating discoveries are sure to follow and NASA’s New Horizons mission to Pluto could be no exception. Having successfully completed its historic flyby of the distant dwarf planet and its assortage of moons on July 14, the spacecraft has now began to slowly transmit its treasure trove of data back to Earth while currently on an outward trajectory from the Pluto system that will propel it farther into the Kuiper Belt. While the whole process of down linking New Horizons’ entire data collection will take the better part of the following 16 months, the preliminary science results to have come from the mission thus far have exceeded all expectations by revealing Pluto’s exotic landscapes in a spectacular manner, while also introducing new mysteries and unanswered questions about this fascinating icy world in the outer reaches of the Solar System.

One of the primary goals in the search for exoplanets is to, hopefully, find an Earth analog or “Earth twin,” an alien world similar to our own. That search is still ongoing, but getting closer – today NASA announced a new exoplanetary discovery that could be described as “Earth’s bigger and older cousin” – Kepler-452b.

A spectacular sunset launch from Cape Canaveral by a United Launch Alliance Delta IV Medium+ rocket placed the U.S. Air Force/ Boeing WGS-7 Wideband Global SATCOM into super synchronous transfer orbit July 23, after a 24 hr. delay due to dangerous thunderstorms in the area.
The 8:07 p.m. EDT launch came at the opening of a 39 minute launch window for the mission to place WGS-7 into a 36,107 x 238 nautical mile orbit, inclined 24 degrees to the equator. The satellite’s own propulsion system will be used to lower apogee and raise perigee to about a 19,232 nautical mile geosynchronous altitude where the satellite will remain fixed over the equator at a specific location, with the rest of the WGS fleet positioned around the planet.

Soyuz TMA-17M lit up the night sky at the Baikonur Cosmodrome in Kazakhstan earlier this evening, delivering Russian cosmonaut Oleg Kononenko, U.S. astronaut Kjell Lindgren, and Japan’s Kimiya Yui safely into orbit to begin a six-hour “fast rendezvous” profile to reach the International Space Station (ISS). Liftoff of the crew’s mammoth Soyuz-FG booster—a direct descendent of the R-7 Intercontinental Ballistic Missile (ICBM), conceived by the legendary Chief Designer, Sergei Korolev, in the 1950s—occurred on time from Baikonur’s historic Site 1/5 at 3:02 a.m. local time Thursday, 23 July (5:02 p.m. EDT Wednesday, 22 July). Shortly after achieving orbit, the Soyuz TMA-17M spacecraft successfully unfurled its electricity-generating solar arrays and communications appendages and executed a series of four maneuvers to accomplish a perfect docking at the station’s Earth-facing (or “nadir”) Rassvet module at about 8:45 a.m. Baikonur time Thursday (10:45 p.m. EDT Wednesday). After pressure and leak checks, the hatches were opened at 10:56 a.m. Baikonur time (12:56 a.m. EDT) Thursday, and Kononenko, Lindgren, and Yui were engulfed in bear-hugs from the incumbent Expedition 44 crew of record-setting Commander Gennadi Padalka and One-Year crewmen Mikhail Kornienko and Scott Kelly, who have been aboard the ISS since March.

Three new spacefarers will rocket toward the International Space Station (ISS) tomorrow (Wednesday, 22 July), destined to spend about five months conducting research, maintenance, and reconfiguration of the U.S. Orbital Segment (USOS) of the multi-national orbiting outpost. As described in yesterday’s AmericaSpace article, veteran Russian cosmonaut Oleg Kononenko and “rookies” Kjell Lindgren of NASA and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) will launch from Site 1/5 at the Baikonur Cosmodrome in Kazakhstan, aboard Soyuz TMA-17M, at 3:02 a.m. local time Thursday (5:02 p.m. EDT Wednesday). In keeping with several previous ISS crews, they will follow a six-hour, four-orbit “fast rendezvous” profile to reach the space station and dock with its Earth-facing (or “nadir”) Rassvet module at about 8:43 a.m. Baikonur time Thursday (10:43 p.m. EDT Wednesday). Current plans call for Kononenko, Lindgren, and Yui to join the incumbent Expedition 44 crew of record-setting Commander Gennadi Padalka and One-Year crewmen Mikhail Kornienko and Scott Kelly, all of whom have been in orbit since March.

Three weeks after the catastrophic loss of a Falcon 9 v1.1 booster, which exploded just 139 seconds after leaving Space Launch Complex (SLC)-40 at Cape Canaveral Air Force Station, Fla.—dooming the seventh dedicated Dragon cargo ship, bound for the International Space Station (ISS)—SpaceX CEO Elon Musk described the status of his company’s ongoing investigation on Monday, 20 July, and revealed that a failed helium tank strut appeared to be the root cause. Over the past weeks, engineering teams have spent thousands of hours matching up data across Falcon 9 v1.1 systems down to the millisecond, in order to properly understand the event which befell their vehicle, within a period of just 0.893 seconds, prior to loss of telemetry. In summarizing the developments, Mr. Musk noted that the accident occurred rapidly, that software modifications might have saved its precious Dragon payload, and that the failure is not expected to impair SpaceX’s goal of launching its first Commercial Crew missions from 2017 onward. At the same time, he added that the Hawthorne, Calif.-based launch services company does not expect to fly another Falcon 9 v1.1 until September 2015, at the soonest.

More than four decades ago, humanity first made landfall on the Moon and Apollo 11 Commander Neil Armstrong and Lunar Module Pilot (LMP) Buzz Aldrin left their footprints on the dusty regolith of the Sea of Tranquility. Over the span of those decades, we have grown familiar with the sights and sounds and experiences of six pairs of intrepid explorers who touched down in areas as diverse as the flat “seas” (or mare) of Tranquility and the Ocean of Storms, the hummocky foothills of Fra Mauro and the mountainous regions of Hadley-Apennine, the Descartes highland plains, and the tiny valley of Taurus-Littrow. To commemorate the anniversary of Apollo 11—which reached the Moon 46 years ago, this week—AmericaSpace will focus not upon the well-documented experiences of the astronauts on the lunar surface, but upon one of the less well-known experiences of life on an alien world: how they managed to rest and sleep aboard the cramped confines of their Lunar Module (LM), surrounded by the ethereal stillness, the silence of ages, and the realization that as they slumbered they were the only living beings on this lifeless, airless world.

Clad in dark civilian suits, three soon-to-be spacefarers descended the aircraft steps at Baikonur Cosmodrome in Kazakhstan on 10 July, primed to become the latest—and somewhat belated—crew members bound for the International Space Station (ISS). Russian cosmonaut Oleg Kononenko, making his third orbital mission, will be joined by NASA astronaut Kjell Lindgren and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA), for a five-month expedition whose very character has morphed significantly in recent weeks. Originally targeted to launch aboard Soyuz TMA-17M on 26/27 May, their flight was postponed in the aftermath of the Progress M-27M launch vehicle failure and in recent weeks has also been overshadowed by the catastrophic 28 June loss of SpaceX’s CRS-7 Dragon cargo ship, which was carrying the first International Docking Adapter (IDA-1) in support of future Commercial Crew operations.
