As U.S. / Russian intelligence controversies swirl between the two countries, a team of Russian rocket technicians will be at Cape Canaveral Air Force Station on Jan. 19 to monitor real time engine data from a United Launch Alliance (ULA) Atlas-V rocket as it lofts the third U.S. Air Force Space Based Infrared System (SBIRS) Geosynchronous Orbit (GEO-3) missile warning satellite into orbit.
This new $1.2 billion, 2-ton spacecraft, intended for hemispheric monitoring, is scheduled for liftoff at 7:46 p.m. EDT at the start of a 40 minute launch window.

On 16 January, a day of reflection—the 14th anniversary of the launch of Space Shuttle Columbia on her final mission—the world lost a shining light in the early annals of human space exploration. Retired Navy Capt. Gene Cernan, veteran of three space missions and the last person to have set foot on the surface of the Moon, has died, aged 82. By cruel coincidence, Cernan passed at exactly the same age as the world’s first Moonwalker, Neil Armstrong. His death leaves just half of the 12 Apollo Moonwalkers still with us, and, when counting Command Module Pilots (CMPs), only 14 humans remain alive to tell tales of traveling beyond low-Earth orbit, across the vast gulf of cislunar space and to our closest celestial neighbor. The news of Cernan’s death broke on Monday afternoon, and NASA has paid touching tribute to an astronaut who “left his mark on the history of exploration.”
Between July 1969 and December 1972, 12 humans left their bootprints in the dusty lunar regolith. Since then, six have passed away—from Apollo 15’s Jim Irwin in August 1991 to Neil Armstrong in August 2012 and, most recently, Apollo 14’s Ed Mitchell, early last year—and only Buzz Aldrin, Al Bean, Dave Scott, John Young, Charlie Duke, and Jack Schmitt remain.

A quarter-century ago, this month, a space mission rooted in disappointment and tragedy finally took flight. Aboard Space Shuttle Discovery, astronauts from the United States, Germany, and Canada embarked on a week-long voyage whose objectives featured the combined efforts of more than 200 scientists, spread across a half-dozen sovereign nations. The first International Microgravity Laboratory (IML-1) was intended to serve as an early precursor for Space Station operations. However, as outlined in yesterday’s AmericaSpace history article, it suffered lengthy delays, caused by the Challenger disaster and later technical troubles which afflicted the shuttle fleet, as well as the untimely death—just months before liftoff—of one of its crew members.

Twelve years ago today, one of the most incredible space missions ever was accomplished: the first landing of a probe on an alien moon. And this wasn’t just any moon, but Titan, largest moon of Saturn and one of the most fascinating worlds in the Solar System. Although much colder than Earth, Titan mimics some of the processes found here such as its hydrological cycle, but with liquid methane/ethane instead of water. Titan had been observed extensively by telescopes and from Saturnian orbit, but this was the first time the surface could be seen up close.

SpaceX has returned to flight operations, with the successful delivery of ten Iridium NEXT global mobile telecommunications satellites to low-Earth orbit. Launch of the Upgraded Falcon 9 took place during an “instantaneous” window at 9:54 a.m. PST Saturday, 14 January, and marked its third flight from Space Launch Complex (SLC)-4E at Vandenberg Air Force Base. Within eight minutes, the first stage completed a smooth touchdown on the Autonomous Spaceport Drone Ship (ASDS), nicknamed “Just Read the Instructions”, which was situated off the coast of San Diego. This marked the first time that the “West Coast” drone ship had hosted a fully successful landing of a Falcon 9 first stage. Aside from the visible triumph of returning to flight and bagging another ASDS landing, however, SpaceX has successfully fulfilled the first part of a seven-year-old contract which will see it place 70 Iridium NEXT satellites into orbit by spring 2018.
“Team Vandenberg takes pride in supporting the launch of Iridium NEXT and SpaceX’s return to flight,” said Col. J. Christopher Moss, 30th Space Wing Commander at Vandenberg and the Launch Decision Authority for the Iridium NEXT mission. “Today’s launch is a testament to the professionalism and commitment to mission assurance, public safety, and mission success on the Western Range.”

Twenty-five years have now passed since the International Space Year (ISY) in 1992, during which 29 national space agencies and 10 international organizations participated in various activities to promote the exploration of both the cosmos and our home planet, Earth. And although a pair of Russian cosmonauts—Aleksandr Volkov and Sergei Krikalev—were aboard the Mir space station on New Year’s Day, the first piloted launch of 1992 was a major venture in life and microgravity sciences, involving over 200 scientists and the respective space agencies of the United States, Germany, France, Canada, and Japan. Laden with the first International Microgravity Laboratory (IML-1), Shuttle Discovery’s STS-42 mission had gone through several changes in crew composition and had been shadowed by disappointment and tragedy in equal measure.

Four months after an Upgraded Falcon 9 booster catastrophically exploded on Space Launch Complex (SLC)-40 at Cape Canaveral Air Force Station, Fla.—destroying both the vehicle and its payload, the Amos-6 communications satellite—SpaceX is ready for its second Return-to-Flight (RTF) in just over a year. The Hawthorne, Calif.-headquartered launch services organization plans to launch 10 Iridium NEXT global mobile telecommunications satellites into low-Earth orbit, no sooner than 9:54 a.m. PST Saturday, 14 January. The mission will be SpaceX’s third launch from Space Launch Complex (SLC)-4E at Vandenberg Air Force Base, Calif.

Expedition 50 Commander Shane Kimbrough and Flight Engineer Thomas Pesquet spent almost six hours working outside the International Space Station (ISS), earlier today (Friday). During U.S. EVA-39—the 39th spacewalk performed from the station’s Quest airlock, in U.S.-built Extravehicular Mobility Units (EMUs) and performed without a Space Shuttle being present—the two astronauts hooked up three new adapter plates and associated electrical connectors for new lithium-ion batteries. As outlined previously by AmericaSpace, over the next few years, a total of 24 lithium-ion batteries will replace 48 aging nickel-hydrogen batteries aboard the Integrated Equipment Assemblies (IEAs) of the station’s four main power-producing truss segments.
In conjunction with last week’s U.S. EVA-38, the first six lithium-ion units have now been installed and activated on the starboard-side S-4 truss segment. The 12 old batteries from S-4 have been removed, with nine of them destined for disposal aboard Japan’s current H-II Transfer Vehicle (HTV-6), later in January, and the other three kept in a dormant configuration as potential on-orbit spares. The remaining 18 lithium-ion batteries will arrive, six at a time, aboard the next three HTVs, which are currently targeted to launch at yearly intervals in early 2018, early 2019 and early 2020. These batteries will be installed into the IEAs aboard the starboard-side S-6 truss and the port-side P-4 and P-6 trusses of the station’s expansive Integrated Truss Structure (ITS).

There have been many incredible planetary missions over the past several decades, from as close as our Moon to the outer reaches of the Solar System. Right now, there are robotic explorers at Mars, Jupiter, Saturn, Ceres, and out past Pluto. But there are two more which have travelled even farther, to the most distant fringes of the Solar System, Voyager 1 and Voyager 2. Although they were launched way back in 1977, they are still active today, studying the region where our planetary system “ends” and interstellar space begins. Now, the Hubble Space Telescope is being used to help provide a “road map” for their future paths forward.

For the second time in 2017, a pair of astronauts will depart the International Space Station (ISS) on Friday, in support of an ambitious, multi-year campaign to remove 48 aging nickel-hydrogen batteries on the Integrated Truss Structure (ITS) and install 24 lithium-ion replacements. Tomorrow’s 6.5-hour EVA-39 will be performed by Expedition 50 Commander Shane Kimbrough—a veteran spacewalker, with three excursions, totaling 19.5 hours, to his credit—and Flight Engineer Thomas Pesquet. As well as making his first career EVA, Pesquet will also become the fourth Frenchman to perform a spacewalk. Just a few weeks shy of his 39th birthday, he will also be the youngest of his countrymen to do so.
