Ever since astronauts began going to space for extended periods of time, it has been known that long-term exposure to zero-gravity or microgravity comes with its share of health effects. These include muscle atrophy and loss of bone density, but also extend to other areas of the body leading to diminished organ function, circulation, and even genetic changes.
For this reason, numerous studies have been conducted aboard the International Space Station (ISS) to determine the extent of these effects, and what strategies can be used to mitigate them. According to a new study which recently appeared in the International Journal of Molecular Sciences, a team of NASA and JAXA-funded researchers showed how artificial gravity should be a key component of any future long-term plans in space.

Let’s be honest, launching things into space with rockets is a pretty inefficient way to do things. Not only are rockets expensive to build, they also need a ton of fuel in order to achieve escape velocity. And while the costs of individual launches are being reduced thanks to concepts like reusable rockets and space planes, a more permanent solution could be to build a Space Elevator.
And while such a project of mega-engineering is simply not feasible right now, there are many scientists and companies around the world that are dedicated to making a space elevator a reality within our lifetimes. For example, a team of Japanese engineers from Shizuoka University‘s Faculty of Engineering recently created a scale model of a space elevator that they will be launching into space tomorrow (on September 11th).

Despite decades of ongoing research, scientists are trying to understand how the four fundamental forces of the Universe fit together. Whereas quantum mechanics can explain how three of these forces things work together on the smallest of scales (electromagnetism, weak and strong nuclear forces), General Relativity explains how things behaves on the largest of scales (i.e. gravity). In this respect, gravity remains the holdout.
To understand how gravity interacts with matter on the tiniest of scales, scientists have developed some truly cutting-edge experiments. One of these is NASA’s Cold Atom Laboratory (CAL), located aboard the ISS, which recently achieved a milestone by creating clouds of atoms known as Bose-Einstein condensates (BECs). This was the first time that BECs have been created in orbit, and offers new opportunities to probe the laws of physics.
Originally predicted by Satyendra Nath Bose and Albert Einstein 71 years ago, BECs are essentially ultracold atoms that reach temperatures just above absolute zero, the point at which atoms should stop moving entirely (in theory). These particles are long-lived and precisely controlled, which makes them the ideal platform for studying quantum phenomena.

This is the purpose of the CAL facility, which is to study ultracold quantum gases in a microgravity environment. The laboratory was installed in the US Science Lab aboard the ISS in late May and is the first of its kind in space. It is designed to advance scientists’ ability to make precision measurements of gravity and study how it interacts with matter at the smallest of scales.
As Robert Thompson, the CAL project scientist and a physicist at NASA’s Jet Propulsion Laboratory, explained in a recent press release:
“Having a BEC experiment operating on the space station is a dream come true. It’s been a long, hard road to get here, but completely worth the struggle, because there’s so much we’re going to be able to do with this facility.”
About two weeks ago, CAL scientists confirmed that the facility had produced BECs from atoms of rubidium – a soft, silvery-white metallic element in the alkali group. According to their report, they had reached temperatures as low as 100 nanoKelvin, one-ten million of one Kelvin above absolute zero (-273 °C; -459 °F). This is roughly 3 K (-270 °C; -454 °F) colder than the average temperature of space.
Because of their unique behavior, BECs are characterized as a fifth state of matter, distinct from gases, liquids, solids and plasma. In BECs, atoms act more like waves than particles on the macroscopic scale, whereas this behavior is usually only observable on the microscopic scale. In addition, the atoms all assume their lowest energy state and take on the same wave identity, making them indistinguishable from one another.

In short, the atom clouds begin to behave like a single “super atom” rather than individual atoms, which makes them easier to study. The first BECs were produced in a lab in 1995 by a science team consisting of Eric Cornell, Carl Wieman and Wolfgang Ketterle, who shared the 2001 Nobel Prize in Physics for their accomplishment. Since that time, hundreds of BEC experiments have been conducted on Earth and some have even been sent into space aboard sounding rockets.
But the CAL facility is unique in that it is the first of its kind on the ISS, where scientists can conduct daily studies over long periods. The facility consists of two standardized containers, which consist of the larger “quad locker” and the smaller “single locker”. The quad locker contains CAL’s physics package, the compartment where CAL will produce clouds of ultra-cold atoms.
This is done by using magnetic fields or focused lasers to create frictionless containers known as “atom traps”. As the atom cloud decompresses inside the atom trap, its temperature naturally drops, getting colder the longer it remains in the trap. On Earth, when these traps are turned off, gravity causes the atoms to begin moving again, which means they can only be studied for fractions of a second.
Aboard the ISS, which is a microgravity environment, BECs can decompress to colder temperatures than with any instrument on Earth and scientists are able to observe individual BECs for five to ten seconds at a time and repeat these measurements for up to six hours per day. And since the facility is controlled remotely from the Earth Orbiting Missions Operation Center at JPL, day-to-day operations require no intervention from astronauts aboard the station.

Robert Shotwell, the chief engineer of JPL’s astronomy and physics directorate, has overseen the project since February 2017. As he indicated in a recent NASA press release:
“CAL is an extremely complicated instrument. Typically, BEC experiments involve enough equipment to fill a room and require near-constant monitoring by scientists, whereas CAL is about the size of a small refrigerator and can be operated remotely from Earth. It was a struggle and required significant effort to overcome all the hurdles necessary to produce the sophisticated facility that’s operating on the space station today.”
Looking ahead, the CAL scientists want to go even further and achieve temperatures that are lower than anything achieved on Earth. In addition to rubidium, the CAL team is also working towards making BECSs using two different isotopes of potassium atoms. At the moment, CAL is still in a commissioning phase, which consists of the operations team conducting a long series of tests see how the CAL facility will operate in microgravity.
However, once it is up and running, five science groups – including groups led by Cornell and Ketterle – will conduct experiments at the facility during its first year. The science phase is expected to begin in early September and will last three years. As Kamal Oudrhiri, JPL’s mission manager for CAL, put it:
“There is a globe-spanning team of scientists ready and excited to use this facility. The diverse range of experiments they plan to perform means there are many techniques for manipulating and cooling the atoms that we need to adapt for microgravity, before we turn the instrument over to the principal investigators to begin science operations.”
Given time, the Cold Atom Lab (CAL) may help scientists to understand how gravity works on the tiniest of scales. Combined with high-energy experiments conducted by CERN and other particle physics laboratories around the world, this could eventually lead to a Theory of Everything (ToE) and a complete understanding of how the Universe works.

Garbage is offloaded from the ISS onto a commercial resupply vehicle and then removed from the station using the Canadarm 2. Credit: NASA
Life aboard the International Space Station is characterized by careful work and efficiency measures. Not only do astronauts rely on an average of 12 metric tons of supplies a year – which is shipped to the station from Earth – they also produce a few metric tons of garbage. This garbage must be carefully stored so that it doesn’t accumulate, and is then sent back to the surface on commercial supply vehicles.
This system works well for a station in orbit. But what about spacecraft that are conducted long-duration missions? These ships will not have the luxury of meeting with a regular cadence of commercial ships that will drop off supplies and haul away their garbage. To address this, NASA is investigating possible solutions for how to handle space trash for deep space missions.
For this purpose, NASA is turning to its partners in the commercial sector to develop concepts for Trash Compaction and Processing Systems (TCPS). In a solicitation issued through the Next Space Technologies for Exploration Partnerships (NextSTEP), NASA recently issued a Board Agency Announcement that called for the creation of prototypes and eventually flight demonstrations that would fly to the ISS.

“NASA’s ultimate goal is to develop capabilities to enable missions that are not reliant on resupply from Earth thus making them more sustainable and affordable. NASA is implementing this by employing a capability-driven approach to its human spaceflight strategy. The approach is based on developing a suite of evolving capabilities that provide specific functions to solve exploration challenges. These investments in initial capabilities can continuously be leveraged and reused, enabling more complex operations over time and exploration of more distant solar system destinations.”
When it comes right down to it, storing trash inside a spacecraft is serious challenge. Not only does it consume precious volume, it can also create physical and biological hazards for the crew. Storing garbage also means that leftover resources can not be repurposed or recycled. All told, the BAA solicitation is looking for solutions that will compact trash, remove biological and physical hazards, and recover resources for future use.
To this end, they are looking for ideas and technologies for a TCPS that could operate on future generations of spaceships. As part of the Advanced Exploration Systems (AES) Habitat’s Logistics Reduction (LR), the TCPS is part of NASA’s larger goal of identifying and developing technologies that reduce logistical mass, volume, and the amount of time the crew dedicates to logistics management.
NASA’ Heat Melt Compactor (HMC), a device that will recover residual water from astronaut’s trash and compact the trash to provide volume reduction, or perhaps some usefulness as an ionizing radiation shield. Credit: NASA
The objectives of the TCPS , as is stated in the Appendix, are fourfold:
“(1) trash compaction to a suitable form for efficient long-endurance storage; (2) safe processing of trash to eliminate and/or reduce the risk of biological activity; (3) stabilize the trash physically, geometrically, and biologically; and (4) manage gaseous, aqueous, and particulate effluents. The TCPS will be the first step toward development and testing of a fully-integrated unit for further Exploration Missions and future space vehicles.”
The development will occur in two phases. In Phase A, selected companies will create a concept TCPS system, conduct design reviews with NASA, and validate them through prototype ground demonstrations. In Phase B, a system will be prepared for transport to the ISS so that a demonstration cant take place aboard the station as early as 2022.
The various companies that submit proposals will not be working in the dark, as NASA has been developing waste management systems since the 1980s. These include recent developments like the Heat Melt Compactor (HMC) experiment, a device that will recover residual water from astronaut’s garbage and compact trash to provide volume reduction (or perhaps an ionizing radiation shield).

Other examples include the “trash to gas” technologies, which are currently being pursued under the Logistics Reduction and Repurposing project (LRR). Using the HMC, this process involves creating methane gas from trash to make rocket propellant. Together, these technologies would not only allow astronauts on long-duration spaceflights to conserve room, but also extract useful resources from their garbage.
NASA plans to host an industry day on July 24th in order to let potential industry partners know exactly what they are looking for, describe available NASA facilities, and answer questions from potential respondents. Official proposals from aspiring partners are due no later than August 22nd, 2018, and whichever proposals make the cut will be tested on the ISS in the coming decade!

After almost seventy years of spaceflight, space debris has become a rather serious problem. This junk, which floats around in Low Earth Orbit (LEO), consists of the spent first rocket stages and non-functioning satellites and poses a major threat to long-term missions like the International Space Station and future space launches. And according to numbers released by the Space Debris Office at the European Space Operations Center (ESOC), the problem is only getting worse.
In addition, space agencies and private aerospace companies hope to launch considerably more in the way of satellites and space habitats in the coming years. As such, NASA has begun experimenting with a revolutionary new idea for removing space debris. It is known as the RemoveDebris spacecraft, which recently deployed from the ISS to conduct a series of Active Debris Removal (ADR) technology demonstrations.
This satellite was assembled by Surrey Satellite Technology Ltd. and the Surrey Space Center (at the University of Surrey in the UK) and contains experiments provided by multiple European aerospace companies. It measures roughly 1 meter (3 feet) on a side and weighs about 100 kg (220 lbs), making it the largest satellite deployed to the ISS to date.
The purpose of the RemoveDebris spacecraft is to demonstrate the effectiveness of debris nets and harpoons at capturing and removing space debris from orbit. As Sir Martin Sweeting, the Chief Executive of SSTL, said in a recent statement:
“SSTL’s expertise in designing and building low cost, small satellite missions has been fundamental to the success of RemoveDEBRIS, a landmark technology demonstrator for Active Debris Removal missions that will begin a new era of space junk clearance in Earth’s orbit.”
Aside from the Surrey Space Center and SSTL, the consortium behind the RemoveDebris spacecraft includes Airbus Defense and Space – the world’s second largest space company – Airbus Safran Launchers, Innovative Solutions in Space (ISIS), CSEM, Inria, and Stellenbosch University. The spacecraft, according to the Surrey Space Center’s website, consists of the following:
“The mission will comprise of a main satellite platform (~100kg) that once in orbit will deploy two CubeSats as artificial debris targets to demonstrate some of the technologies (net capture, harpoon capture, vision-based navigation, dragsail de-orbitation). The project is co-funded by the European Commission and the project partners, and is led by the Surrey Space Centre (SSC), University of Surrey, UK.”
For the sake of the demonstration, the “mothership” will deploy two cubesates which will simulate two pieces of space junk. For the first experiment, one of the CubeSats – designated DebrisSat 1 – will inflate its onboard balloon in order to simulate a larger piece of junk. The RemoveDebris spacecraft will then deploy its net to capture it, then guide it into the Earth’s atmosphere where the net will be released.
The second CubeSat, named DebrisSat 2, will be used to test the mothership’s tracking and ranging lasers, its algorithms, and its vision-based navigation technology. The third experiment, which will test the harpoon’s ability to capture orbiting space debris, is set to take place next March. For legal reasons, the harpoon will not be tested on an actual satellite, and will instead consist of the mothership extending an arm with a target on the end.
The harpoon will then be fired on a tether at 20 meters per second (45 mph) to tests it accuracy. After being launched to the station back on April 2nd, the satellite was deployed from the ISS’ Japanese Kibo lab module on June 20th by the stations’ Canadian robotic arm. As Guillermo Aglietti, the director of the Surrey Space Center, explained in an interview with SpaceFlight Now before the spacecraft was launched to the ISS:
“The net, as a way to capture debris, is a very flexible option because even if the debris is spinning, or has got an irregular shape, to capture it with a net is relatively low-risk compared to … going with a robotic arm, because if the debris is spinning very fast, and you try to capture it with a robotic arm, then clearly there is a problem. In addition, if you are to capture the debris with a robotic arm or a gripper, you need somewhere you can grab hold of your piece of debris without breaking off just a chunk of it.”
The net experiment is currently scheduled for September of 2018 while the second experiment is scheduled for October. When these experiments are complete, the mothership will deploy its dragsail to act as a braking mechanism. This expandable sail will experience collisions with air molecules in the Earth’s outer atmosphere, gradually reducing its orbit until it enters the denser layers of Earth’s atmosphere and burns up.
This sail will ensure that the spacecraft deorbits within eights weeks of its deployment, rather than the estimated two-and-half years it would take to happen naturally. In this respect, the RemoveDebris spacecraft will demonstrate that it is capable of tackling the problem of space debris while not adding to it.
In the end, the RemoveDebris spacecraft will test a number of key technologies designed to make orbital debris removal as simple and cost-effective as possible. If it proves effective, the ISS could be receiving multiple RemoveDebris spacecraft in the ftureu, which could then be deployed gradually to remove larger pieces of space debris that threaten the station and operational satellites.
Conor Brown is the external payloads manager of Nanoracks LLC, the company that developed the Kaber system aboard the Kibo lab module to accommodate the increasing number of MicroSats being deployed from the ISS. As he expressed in a recent statement:
“It’s wonderful to have helped facilitate this ground-breaking mission. RemoveDebris is demonstrating some extremely exciting active debris removal technologies that could have a major impact to how we manage space debris moving forward. This program is an excellent example of how small satellite capabilities have grown and how the space station can serve as a platform for missions of this scale. We’re all excited to see the results of the experiments and impact this project may have in the coming years.”
In addition to the RemoveDebris spacecraft, the ISS recently received a new tool for detecting space debris. This is known as the Space Debris Sensor (SDS), a calibrated impact sensor mounted on the exterior of the station to monitor impacts caused by small-scale space debris. Coupled with technologies designed to clean up space debris, improved monitoring will ensure that the commercialization (and perhaps even colonization) of LEO can begin.

On March 1st, 2016, American astronaut Scott Kelly returned to Earth after spending a total of 340 days aboard the International Space Station (ISS). As part of NASA’s goal to send astronauts on long-duration space flights to Mars and beyond, this record-setting stay in space was designed to test the limit of human endurance in a microgravity environment.
Also known as the Twin Study, this experiment consisted of Kelly spending nearly a year in space while his identical twin (Mark Kelly) remained on Earth. Since Kelly’s return, the two have been subjected to medical tests to see what long-term effects microgravity has had of Scott’s Kelly’s physique. The final results of this test, which were just released, reveal that Scott has experienced changes at the genetic level.
The study was conducted by NASA’s Human Research Program, and the preliminary findings were released at their Investigator’s Workshop on the week of January 23rd, 2017. According to these findings, Scott Kelly showed indications of inflammation, changes in his telomeres and telomerase (parts of the chromosonal system related to aging), a decrease in bone density and gastrointestinal changes – all of which were expected.

As NASA reported in their preliminary findings:
“By measuring large numbers of metabolites, cytokines, and proteins, researchers learned that spaceflight is associated with oxygen deprivation stress, increased inflammation, and dramatic nutrient shifts that affect gene expression… After returning to Earth, Scott started the process of readapting to Earth’s gravity. Most of the biological changes he experienced in space quickly returned to nearly his preflight status. Some changes returned to baseline within hours or days of landing, while a few persisted after six months.”
At the same time, the study took into account possible genomic and cognitive changes between the two brothers. These findings were recently clarified by NASA, which indicated that 93% of Scott Kelly’s genes returned to normal after he returned to Earth while the remaining 7% points were missing. These were attributed to “longer-term changes in genes related to his immune system, DNA repair, bone formation networks, hypoxia, and hypercapnia.”
In other words, in addition to the well-documented effects of microgravity – such as muscle atrophy, bone density loss and loss of eyesight – Scott Kelly also experienced health effect caused by a deficiency in the amount of oxygen that was able to make it to his tissues, an excess of CO2 in his tissues, and long-term effects in how his body is able to maintain and repair itself.
At the same time, the report indicated that Scott Kelly experienced no significant changes when it came to cognitive performance. The preliminary findings touched on this, indicating that Scott showed a slight decrease in speed and accuracy when undergoing cognitive performance testing compared to his brother. This decrease was more pronounced when he first landed, but was attributed to readjustment to Earth’s gravity.
Mathias Basner – a professor at the University of Pennsylvania, Philadelphia, who was in charge of conducting the tests – also found no real difference in cognition between 6 month and 12 month missions. This is especially important since typical stays aboard the ISS last six months, whereas long term missions to Mars would take 150-300 days – depending on the alignment of the planets and the speed of the spacecraft.
A two way trip to Mars, as well as the time spent in Mars lower-gravity environment (37.6 % that of Earth’s), could take multiple years. As such, the Twin Study was intrinsic to NASA’s efforts to prepare for its proposed “Journey to Mars“, which is expected to take place sometime in the 2030s. These and other studies being conducted aboard the ISS seek to determine what the long-term effects on astronaut health will be, and how they can be mitigated.
The NASA Twin Study was the result of a partnership between 10 individual investigations, 12 colleges and universities, NASA’s biomedical labs and the National Space Biomedical Research Institute Consortium.
Scott Kelly’s stay in space and the Twin Study will also be the subject of a PBS documentary titled “Beyond a Year in Space“. Be sure to check out the teaser trailer here:

NASA and SpaceX have jointly decided to move forward with the Dragon CRS-13 cargo blastoff apparently because the mission does not involve use of the problematical payload fairing that halted last weeks planned Falcon 9 launch with the rocket and the mysterious Zuma payload.
Zuma was ready and waiting at pad 39A for the GO to launch that never came.
Then after a series of daily delays SpaceX ultimately announced a ‘stand down’ for super secret Zuma at pad 39A on Friday, Nov. 17, for the foreseeable future.

Since SpaceX’s gumdrop shaped Dragon cargo freighter launches as a stand alone aerodynamically shielded spacecraft atop the Falcon 9, it does not require additional protection from atmospheric forces and friction housed inside a nose cone during ascent to orbit unlike satellites with many unprotected exposed surfaces, critical hardware and delicate instruments.
Thus Dragon is deemed good to go since there currently appear to be no other unresolved technical issues with the Falcon 9 rocket.
“NASA commercial cargo provider SpaceX is targeting its 13th commercial resupply services mission to the International Space Station for no earlier than 2:53 p.m. EST Monday, Dec. 4,” NASA announced on the agency blog and social media accounts.
But the targeted Dec 4 liftoff from Space Launch Complex 40 on Cape Canaveral Air Force Station, FL, was cast in doubt after SpaceX disclosed the payload fairing issue related launch delay on Friday.
Since last week SpaceX engineers have been busy taking the time to carefully scrutinize all the pertinent fairing data before proceeding with the top secret Zuma launch.
“We have decided to stand down and take a closer look at data from recent fairing testing for another customer,” said SpaceX spokesman John Taylor last Friday.

All of SpaceX’s launches this year from Florida’s Spaceport have taken place from NASA’s historic Launch Complex-39A at the Kennedy Space Center.
Pad 39A became SpaceX’s only operational Florida Space Coast launch pad following a catastrophic launch pad accident last year on Sept. 1, 2016 that took place during a routine fueling test that suddenly ended in a devastating explosion and fire that completely consumed the Falcon 9 rocket and Amos-6 payload and heavily damaged the pad and support infrastructure.

Since the Amos-6 accident workers raced to finish refurbishments to NASA’s long dormant pad 39A to transform into operational status and successfully launched a dozen missions this year.
Simultaneously additional crews have been hard at work to repair damaged pad 40 so that flights can resume there as soon as possible for the bulk of NASA, commercial and military contracted missions.
The Dragon CRS-13 mission was recently announced as the maiden mission for the reopening of pad 40.
Altogether Dragon CRS-13 will count as the fourth SpaceX Dragon liftoff of 2017.
The 20-foot high, 12-foot-diameter Dragon CRS-13 vessel will carry about 3 tons of science and supplies to the orbiting outpost and stay about 4 weeks.
It will be a reused Dragon that previously flew on the CRS-6 mission.
“The Dragon [CRS-13] spacecraft will spend about a month attached to the space station,” NASA said.

The prior Dragon CRS-12 resupply ship launched from pad 39A on Aug. 14, 2017 from KSC pad 39A and carried more than 6,400 pounds ( 2,900 kg) of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex.

Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) assisted by NASA astronaut Randy Bresnik then deftly maneuvered the International Space Station’s 57.7-foot-long (17.6 meter-long) Canadarm2 robotic arm to grapple and successfully capture the Cygnus cargo freighter at 5:04 a.m., Tuesday Nov. 14.
The station was orbiting 260 statute miles over the South Indian Ocean at the moment Nespoli grappled the S.S. Gene Cernan Cygnus spacecraft with the Canadian-built robotic arm.
Ground controllers at NASA’s Mission Control at the Johnson Space Center in Texas, then maneuvered the arm and robotic hand grappling Cygnus towards the exterior hull and berthed the cargo ship at the Earth-facing port of the stations Unity module.
The berthing operation was completed at 7:15 a.m. after all 16 bolts were driven home for hard mating as the station was flying 252 miles over the North Pacific in orbital night.

Soon thereafter at 5:04 a.m., Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) assisted by NASA astronaut Randy Bresnik successfully captured Orbital ATK’s Cygnus cargo freighter using the International Space Station’s 57.7-foot-long (17.6 meter-long) Canadarm2 robotic arm.
The station was orbiting 260 statute miles over the South Indian Ocean at the moment Nespoli grappled the S.S. Gene Cernan Cygnus spacecraft with the Canadian-built robotic arm.
Nespoli and Bresnik were working at a robotics work station inside the seven windowed domed Cupola module that offers astronauts the most expansive view outside to snare Cygnus with the robotic arms end effector.
The Cygnus cargo freighter – named after the last man to walk on the Moon – reached its preliminary orbit nine minutes after blasting off early Sunday atop the upgraded 230 version of the Orbital ATK Antares rocket from NASA’s Wallops Flight Facility in Virginia.
The flawless liftoff of the two stage Antares rocket took place shortly after sunrise Sunday at 7:19 a.m. EST, Nov. 12, rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia.

Sunday’s spectacular Antares launch delighted spectators – but came a day late due to a last moment scrub on the originally planned Veteran’s Day liftoff, Saturday, Nov. 11, when a completely reckless pilot flew below radar into restricted airspace just 5 miles away from the launch pad – forcing a sudden and unexpected halt to the countdown under absolutely perfect weather conditions.
After a carefully choreographed series of intricate thruster firings to raise its orbit over the next two days, the Cygnus spacecraft on the OA-8 resupply mission for NASA arrived in the vicinity of the orbiting research laboratory.
With Cygnus firmly in the grip of the robots hand, ground controllers at NASA’s Mission Control at the Johnson Space Center in Texas, maneuvered the arm towards the exterior hull and berth the cargo ship at the Earth-facing port of the stations Unity module.
1st stage capture was completed at 7:08 a. EST Nov 14.
After driving in the second stage gang of bolts, hard mate and capture were completed at 7:15 a.m.
The station was flying 252 miles over the North Pacific in orbital night at the time of berthing.

NASA WALLOPS FLIGHT FACILITY, VA – An Orbital ATK Antares rocket successfully blasted off this morning, Sunday, Nov. 12, from the eastern shore of Virginia on a NASA contracted mission bound for the International Space Station (ISS) carrying a Cygnus cargo ship loaded with nearly 4 tons of vital science and supplies.
The two stage Antares rocket launched flawlessly shortly sunrise Sunday at 7:19 a.m. EST, Nov. 12 on an upgraded version of the Antares rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia carrying the Cygnus resupply spacecraft named in honor of Gene Cernan, the last man to walk on the Moon.

The launch came a day late due to a last moment scrub on the originally planned Veteran’s Day liftoff, Saturday, Nov. 11, when a reckless pilot flew below radar into restricted airspace just 5 miles away from the launch pad – forcing a sudden and unexpected halt to the countdown under absolutely perfect weather conditions.
Finally the rocket roared off the pad Sunday under cloudy skies – to the delight of a spectators, with a brilliant flash of light. Slowly at first and then accelerating almost straight up before arcing over just slightly in a southeasterly direction and soon disappearing into the thick clouds. In fact it was so load that local residents told me their windows and houses shook and rattled.
Saturday’s sudden scrub disappointed tens of thousands of spectators who had gathered around the East coast launch region and beyond for a rare chance to see the launch of a powerful rocket on a critical cargo delivery mission for NASA conducted the benefit of the six person crew serving on the station to advance science for all of humanity.
The pilot may have intentionally flown the plane low enough to avoid detection so he could take photos for profit.
As a result of this extremely serious violation of flight rules which raises significant safety and base security issues the FAA and NASA are now undertaking an intense review of rules after the repeated serious incursions by planes and boats into exclusion zones during launches, and what penalties and fines should be applied.

The Cygnus spacecraft dubbed OA-8 is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing and reliable basis.
“Today’s successful launch of the OA-8 Cygnus on our Antares launch vehicle once again demonstrates the reliability of Orbital ATK’s hardware along with our commitment to deliver critical cargo to astronauts on the International Space Station,” said Frank Culbertson, President of Orbital ATK’s Space Systems Group.
“Soon, Cygnus will rendezvous with the space station to deliver valuable scientific experiments, hardware and crew supplies to the orbiting platform. On this mission, Cygnus will again display its flexibility as an in-orbit science platform by supporting experiments to be performed inside the cargo module while attached to the space station. We are proud to dedicate this mission to Apollo astronaut Gene Cernan and his family and look forward to celebrating the OA-8 contributions to science in his name.”
After a two day orbital chase the S.S. Gene Cernan will arrive in the vicinity of the space station early Tuesday, Nov. 14. Cygnus will be grappled by Expedition 53 astronaut Paolo Nespoli of ESA (European Space Agency) of Italy at approximately 4:50 a.m. EST on November 14 using the space station’s robotic arm. He will be assisted by NASA astronaut Randy Bresnik.
NASA TV will provide live coverage of the rendezvous and grappling.
Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.
The 14 story tall commercial Antares rocket launched for only the second time in the upgraded 230 configuration – powered by a pair of the new Russian-built RD-181 first stage engines.
The rocket performed flawlessly said Kurt Eberly, Orbital ATK deputy program manager for Antares, during the post launch briefing at NASA Wallops.
There was only a slight over performance of the Castor XL solid fueled second stage, which was all to the good – as occurred during the first launch of the upgraded Antares a year ago in October 2016 on the OA-5 resupply mission.
Indeed the overperformance of the second stage may allow Orbital ATK to load the Cygnus with an even heavier cargo load than previously foreseen.
On this flight,the Cygnus OA-8 spacecraft is jam packed with its heaviest cargo load to date!
