Orbital Sciences Corp. is ready to deliver its third Cygnus unpiloted cargo craft to the International Space Station (ISS), with liftoff of the ORB-3 mission scheduled to occur from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Va., at 6:45 p.m. EDT Monday, 27 October. Coming 37 minutes after local sunset, this will be the first occasion on which Orbital’s two-stage Antares booster has launched in the hours of darkness. The launch has been subject to several days of delay, principally caused by the recent effects of Hurricane Gonzalo, and assuming an on-time liftoff on Monday evening Cygnus should complete its rendezvous and berthing at the ISS on the morning of Sunday, 2 November. It will spend about a month attached to the Earth-facing (or “nadir”) port of the station’s Harmony node and will deliver Orbital’s largest-ever load of equipment and supplies to the incumbent Expedition 41 crew, totaling 5,050 pounds (2,290 kg).

Almost 50 years ago, the United States almost staged its first rendezvous mission between unpiloted and piloted vehicles in low-Earth orbit. An Atlas-Agena target craft was almost successfully launched and two astronauts—Gemini VI crewmen Wally Schirra and Tom Stafford—almost followed it on a voyage which might have pushed America far ahead of the Soviet Union in the race to plant human bootprints on the Moon before the end of the decade.

From NASA: “The view from inside NASA Goddard’s Thermal Vacuum Chamber shows the JWST [James Webb Space Telescope] heart being lowered by crane in preparation of weeks of space environment testing.” An essential component of the James Webb Space Telescope has just completed and survived vacuum testing in extremely cold conditions.

You may have survived cold weather (unless, perhaps, you live in Florida, or near the equator), but you haven’t seen a cold snap like this, at least on Earth: -387 degrees Fahrenheit (40 degrees Kelvin), which, according to NASA, is 260 degrees colder than any temperature recorded on our home planet.
Recently, what has been described as the “heart” of the James Webb Space Telescope (JWST)—the Integrated Science Instrument Module (ISIM), which contains four essential science instruments—underwent and survived a “deep freeze” test inside a thermal vacuum chamber located at Goddard Space Flight Center in Greenbelt, Md. The integral component spent 116 days within the chamber, meant to replicate the harsh conditions the space telescope will undergo as it will be deployed to an environment considered extreme, even for space. This test occurred during the summer months. In July, NASA announced that testing was completed on the telescope’s backplane structure; the completion of these tests are milestones for those working on the project.

Scheduled for launch in early 2015, NASA’s Soil Moisture Active Passive, or SMAP mission, will track Earth’s water into one of its last hiding places: the soil. SMAP soil moisture data will, among other things, aid in predictions of agricultural productivity, weather and climate. Image Credit: NASA
“Follow the water”: This theme has driven NASA’s Mars robotic exploration missions in the last 20 years, as part of the space agency’s efforts to understand the role of the life-enabling liquid in the physical processes that have shaped the Red Planet throughout its history. A similar understanding of the importance of water is the focus of another NASA mission, the Soil Moisture Active Passive, or SMAP, which will enable the global mapping of the moisture distribution and freeze-thaw state, not of the Martian soil but that of our home planet instead, in unprecedented detail allowing scientists to gain a better understanding of the ways that soil moisture affects Earth’s hydrological, energy, and carbon cycles.

It wasn’t that long ago that Earth was thought to be the only place in the Solar System capable of having liquid water oceans, but now we know of several moons that do as well, including Europa and Enceladus, and likely Titan and Ganymede as well. In all these cases, the oceans are below ground, similar to ocean water below ice sheets at the Earth’s poles. Now there is yet another moon which might be added to this special list: Saturn’s moon Mimas.

For the seventh time in 2014—and the third occasion in less than three weeks—a pair of spacewalkers toiled outside the International Space Station (ISS) earlier today (Wednesday, 22 October). Expedition 41 Commander Max Surayev and Flight Engineer Aleksandr Samukutyayev worked briskly for three hours and 38 minutes to remove and discard a scientific experiment package and a pair of unneeded rendezvous antennas, collect samples from the exterior of the Russian Orbital Segment (ROS), and conduct a comprehensive photo-documentation task. Today’s EVA marked the second career excursion for both Surayev and Samokutyayev and is expected to be the final ISS spacewalk of the year.

NASA’s Opportunity rover snapped the first-ever image of a comet from the surface of Mars during a once-in-a-lifetime opportunity as Comet Siding Spring (Comet C/2013 A1) made the closest known flyby of either Earth or Mars in recorded history—missing the Red Planet by a mere 87,000 miles (139,500 kilometers).
Opportunity captured the spectacular and history-making view of the “fuzzy” Oort Cloud comet by pointing her camera high up in the pre-dawn Martian sky on Sunday, Oct. 19, said “quite excited” Opportunity science team member Mark Lemmon of Texas A&M University, exclusively to AmericaSpace today (Oct. 20). See rover photo above with our enhanced view revealing more comet detail.

MICHOUD ASSEMBLY FACILITY, NEW ORLEANS, LA — The first pieces of rocket hardware have been loaded onto NASA’s gigantic new weld tool tasked with assembling the core stage fuel tanks for NASA’s mammoth new heavy lift rocket—the Space Launch System (SLS)—that will one day boost “Humans to Mars.”
The road to SLS production and first launch has started, with acceptance testing using parts from the over 34,000 square feet of real metal components already manufactured.
