Cygnus Cargo Spacecraft Installed on ISS for Critical Supplies Delivery
November 14, 2017

The Cygnus S.S. Gene Cernan arrived at the International Space Station on Tuesday for a robotic capture and berthing to become a temporary part of the orbiting laboratory for the delivery of over three metric tons of supplies, maintenance gear and research. Cygnus enjoyed a particularly smooth flight after Sunday's liftoff from Virginia's Eastern Shore, arriving at the Station's doorstep for a straight-up approach to the capture position to mark the start of a three-week stay at ISS highlighted by cargo transfers and a planned end-of-mission test to collect data for future Commercial Crew missions.

Cygnus took flight at 12:19:55 UTC on Sunday when its Antares launch vehicle lifted off from Pad 0A at the Wallops Flight Facility. Flying in its upgraded configuration for the second time, Antares fired its twin RD-181 engines for three and a half minutes, shed its payload fairing during a brief passive flight phase and burned its solid-fueled second stage for two minutes and 40 seconds to send Cygnus into orbit. Performance by the upgraded launch vehicle again surpassed the intentionally conservative simulations and placed Cygnus into a slightly higher orbit than planned.

The 6,200-Kilogram Cygnus spacecraft started out in an orbit of 300 by 331 Kilometers at the expected inclination of 51.63 degrees. Solar array deployment occurred after the vehicle made its first lap around the planet and Mission Controllers in Dulles, Virginia were able to give Cygnus a clean bill of health after initial checkouts in orbit. Within a few hours of launch, Cygnus completed its first large orbit-raising maneuver with its BT-4 main engine, lifting the apogee to 360 Kilometers.

More burns were performed on Sunday and Monday as Cygnus approached the Space Station from behind and below for initiation of the rendezvous when Cygnus was in an orbit four Kilometers below the Space Station's 401 x 408-Kilometer orbit. When reaching a range of 28 Kilometers, Cygnus entered the relative navigation phase of the rendezvous, beginning to receive GPS data from the Space Station through a space-to-space communications link in order to compare it against its own GPS readings to obtain a more precise relative position fix.

Joint operations between Dulles and NASA's Mission Control Center in Houston began before Cygnus was given clearance for its first Approach Delta-V Burn and a coelliptic maneuver that positioned the craft 1.5 Kilometers below ISS. Next was the Approach Initiation Maneuver that put the spacecraft on a path to intercept the Station's R-Bar to arrive at a position around 350 meters straight below ISS.

Aboard the Station, ESA Astronaut Paolo Nespoli served as the robotics operator on Tuesday while Expedition 53 commander Randy Bresnik handled communications with the ground and commanding of Cygnus through the Hardware Command Panel. At a range of 250 meters, Cygnus hit the brakes to enter a planned hold dedicated to the transition from Relative GPS navigation to the craft's Proximity Navigation System featuring a laser-based 3D sensor that captures 3D data of the target vehicle that is then compared with a computer model of the known shape of the target to deliver relative position, range and range rate measurements to guide the spacecraft to an on-target arrival.

The 250-meter hold was extended slightly, causing the rendezvous to drift around ten minutes behind schedule before the spacecraft was commanded into Approach Mode to advance to 30 meters. While Cygnus again held position, teams on the ground configured the spacecraft for final approach and the crew in orbit went through their procedure review before providing clearance for final approach. Gently firing its thrusters, Cygnus slowly covered the final 18 meters to the capture position, taking around 15 minutes.

Arriving within reach of Canadarm2, Cygnus automatically reduced relative rates to hold perfectly still while the crew reconfigured cameras and took the brakes off the robotic arm in preparation for capture. Mission Control provided a GO and Paolo Nespoli began driving the arm into position over the grappling pin of the craft's Power & Video Grapple Fixture with Cygnus moving into Free Drift just before capture. A good capture was confirmed at 10:04 UTC followed by engaging latches within the arm's Latching End Effector to form a power and video bridge to Cygnus.

The crew then handed robotics off to controllers on the ground for the berthing operation which has become close to routine by this point. Moving swiftly through their procedures, ROBO controllers maneuvered Cygnus into its pre-berthing position on the Earth-facing Common Berthing Mechanism of the Unity Module. With the help of the Centerline Berthing Camera System, Cygnus was positioned with millimeter accuracy before capture latches were closed to establish first stage capture.

Four sets of four bolts were then driven to firmly pull Cygnus in and form a pressure seal between the Unity module and the spacecraft with second stage capture marked at 12:15 UTC. After final bolt-loading, the crew will be cleared to press into leak checks and outfitting of the vestibule between the two spacecraft before Cygnus can be opened for business with plenty of cargo transfers ahead for the four U.S. Segment crew members over the course of the next three weeks.

Cygnus OA-8 is the fifth U.S. resupply craft reaching ISS this year, coming after the OA-7 mission that launched on Atlas V and three science-heavy Dragon missions. In contrast to recent Dragons, cargo on the Cygnus is primarily comprised of supplies and systems hardware to ensure ISS can remain in a comfortable consumables situation. With the OA-8 cargo on board, ISS is looking good for supplies until June 2018 with food being the limiting consumable which is usually the case per standard ISS supply management.

Cygnus OA-8 is loaded with 3,229 Kilograms of pressurized cargo comprising 1,240 Kilograms of crew supplies including food provisions and clothing, 851kg of vehicle hardware, 740kg of utilization hardware including new experiments and materials for ongoing studies, and 166kg of spacewalk equipment and computer resources. Two powered polar freezers are installed aboard Cygnus, holding cold stowage items for biological experiments as well as fresh fruit and vegetables plus ice cream for the crew.

Hardware aboard the Cygnus includes replacement gas bottles for the Combustion Integrated Rack for upcoming research into combustion dynamics in microgravity, a Rodent Habitat to provide a home for the next Rodent Research mission flying on SpaceX, and parts for the Station's 3D printer. Space Tango's TangoLab module is set for a unique demonstration during this mission, taking up temporary residence aboard the Cygnus spacecraft to prove the feasibility of using the cargo module as an extension to the scientific modules of the Space Station.

Cygnus is also carrying a series of CubeSats – two are to be transferred to the Kibo module for installation in a NanoRacks deployer to be released via the Station's Japanese Robotic Arm while Cygnus itself hosts a CubeSat deployer holding 14 satellites for deployment into an orbit around 100 Kilometers above ISS after Cygnus departs the Station.

Cygnus is booked for a short stay of just under three weeks, making for a fairly packed timeline for unloading the spacecraft and re-loading it with trash and no-longer-needed hardware. Unberthing is planned for December 3rd to position Cygnus for an overnight session of radio and GPS testing to verify Commercial Crew vehicles arriving and departing the Harmony module can do so without radio interference. Released on December 4th, Cygnus will be guided into the CubeSat deployment orbit above ISS and then conduct maneuvers toward a destructive re-entry over the Pacific to close out its mission.

На счет веса корабля. Я тут провел анализ, на основании информации по запускам "Лебедя" ранее.
По моим прикидкам корабль без топлива должен весить 6488 кг? Его баки вмещают до 830 кг топлива? РН на низкую опорную орбиту может вытащить около 7000 кг. Из чего можно сделать вывод о массе корабля на старте - 7000 - 7300 кг.

Orbital ATK's Cygnus Rendzevous and Installation to the International Space Station

NASA

Опубликовано: 14 нояб. 2017 г.

Orbital ATK's Cygnus spacecraft arrived at the International Space Station Nov. 14 after a two-day journey following its launch Nov. 12 on the company's Antares rocket from the Wallops Flight Facility in Virginia. Dubbed the "SS Gene Cernan" after the late Gemini and Apollo astronaut who was the last man to walk on the moon, Cygnus was captured by Expedition 53 Flight Engineer Paolo Nespoli of ESA (the European Space Agency) and Commander Randy Bresnik of NASA using the station's Canadarm2 robotic arm.

Cygnus arrives at space station with food, experiments and cache of CubeSats
November 14, 2017 Stephen Clark

A commercial cargo craft owned and operated by Orbital ATK wrapped up a two-day journey to the International Space Station on Tuesday, delivering ice cream and pizza for the lab's six-person crew and hardware for a slew of research experiments, including CubeSats slated for orbital deployments in the coming weeks.

Guided by GPS and laser navigation sensors, the Cygnus supply ship approached the space station fr om below, pausing at several pre-planned hold points for astronauts and ground controllers to check the progress of the rendezvous.

After it reached a final hold point around 30 feet, or 10 meters, fr om the orbiting complex, astronaut Paolo Nespoli took control of the station's 58-foot-long (17-meter) Canadian-built robotic arm to grapple the Cygnus spaceship at 5:04 a.m. EST (1004 GMT) as the vehicles sailed 260 miles (418 kilometers) over the southeastern Indian Ocean.

Ground controllers commanded the robotic arm to place the Cygnus supply carrier on the Unity module's Earth-facing berthing mechanism a few hours later. Sixteen bolts drove closed in four steps to firmly connect the newly-arrived cargo craft with the space station.

The automated arrival came two days after the Cygnus resupply vessel lifted off Sunday from a launch pad on Virginia's Eastern Shore, riding an Orbital ATK Antares rocket into orbit to kick off its orbital pursuit of the space station.

Astronauts opened hatches leading into the Cygnus' pressurized cargo module later Tuesday, a day earlier than planned.

Crew members will unload 7,118 pounds (3,229 kilograms) of cargo from the Cygnus spacecraft's pressurized module beginning Wednesday. The supply shipment includes:

[/li]
• 2,734 pounds (1,240 kilograms) of crew supplies
• 1,631 pounds (740 kilograms) of science investigations
• 291 pounds (132 kilograms) of spacewalk equipment
• 1,875 pounds (851 kilograms) of vehicle hardware
• 75 pounds (34 kilograms) of computer resources
  

Fresh fruit and vegetables are among the goodies riding inside a refrigerator on Cygnus spacecraft.

"The crew is going to get some treats when they open up the hatch," said Dan Hartman, NASA's deputy space station program manager, before the launch.

The station's four astronauts living and working in the U.S. segment of the outpost will get to work on experiments carried in the Cygnus. For the first time, they will also relocate some research hardware already on the station into a rack inside the Cygnus cargo module, using the facility as a temporary research base.

Among the scientific supplies delivered to the station Tuesday were gas bottles to support an advanced combustion microgravity experiment, a habitat for research rodents launching on a future mission, and items for a 3D printer aboard the orbiting laboratory, according to Camille Alleyne, associate space station program scientist at NASA's Johnson Space Center in Houston.

Two CubeSats will be transferred inside the space station to join three others for release into orbit through the Japanese lab module's airlock.

One of the CubeSats is named the E. Coli Antimicrobial Satellite, or EcAMSat, is about the size of a small briefcase. Developed by engineers at NASA's Ames Research Center and scientists at Stanford University, EcAMSat will study the antibiotic resistance in space of E. coli, a bacterial pathogen responsible for urinary tract infection in humans and animals.

EcAMSat's mission is expected to last more than a year, and two types of E. coli cells — a wild and a mutant strain — contained in 48 microfluidic wells inside the CubeSat's miniature laboratory will be activated, grown and tested once the 23-pound (10-kilogram) satellite is ejected from the station's Japanese robotic arm, according to Stevan Spremo, EcAMSat's project manager.

"With this, we believe that we'll learn more about antibiotic resistance in the microgravity environment, wh ere E. coli are known to grow more virulently in space," Spremo said.

The results could help protect astronauts on future space missions and develop countermeasures that may be useful for humans on Earth, he said.

The other small spacecraft carried on the OA-8 mission and destined for deployment through the Kibo airlock is TechEdSat 6, another experimental CubeSat from the Ames Research Center in partnership with San Jose State University and the University of Idaho.

TechEdSat 6 is the latest in a series of CubeSats testing an "exo-brake" de-orbit system, a drag device that uses aerodynamic forces — and not propulsion — to re-enter the atmosphere. The technology could eventually allow some space station research samples to return to Earth sooner, and at less expense.

Station astronauts will repack the Cygnus spacecraft's Italian-built logistics module with trash before closing hatches and detaching the supply ship from the Unity module with the robotic arm Dec. 3.

Mission control will maneuver the Cygnus a few feet from another berthing port on the station's Harmony module, wh ere crew capsules from Boeing and SpaceX are expected to dock once they are ready to begin flying astronauts into orbit.

Engineers will use the Cygnus spacecraft to simulate the presence of a commercial crew craft at Harmony's space-facing port and check to ensure it does not block GPS navigation signals from reaching the space station.

Once those tests are finished, the robotic arm will release Cygnus on Dec. 4, and Orbital ATK's ground team will send commands to raise the ship's orbit to an altitude of around 300 miles (500 kilometers).

In that orbit, Cygnus will deploy 14 more CubeSats — ranging in size from a Rubik's Cube to a loaf of bread — from an external device provided by NanoRacks, a Houston-based company that offers small satellite deployments on space station cargo flights.

"OA-8 is yet another unique mission for NanoRacks," said Henry Martin, NanoRacks' senior mission manager. "We're thrilled to have a full external Cygnus deployer, displaying its maximum capability. This mission also brings new customers from outside the industry into space while continuing partnerships with existing customers like Spire for their ongoing satellite constellation. Notably, this mission will also deploy our first-ever propulsive satellite from the Cygnus spacecraft."

Eight of the CubeSats will join Spire Global's commercial weather satellite network, which derives humidity and temperature profiles by measuring GPS navigation signals passing through Earth's atmosphere.

Two AeroCube satellites assembled by the Aerospace Corp. for NASA's Optical Communications and Sensor Demonstration, or OCSD, mission will test high-speed laser communications and an innovative water-based propulsion system to maneuver in close proximity to one another.

"Our primary mission for OCSD is to demonstrate laser communications by using a laser on the spacecraft to downlink data to our optical ground station on Mt. Wilson in California," said Richard Welle, Aerospace senior scientist and one of the principal investigators for OCSD. "This is the first CubeSat laser communications system that will demonstrate an optical downlink. This compact laser package with its potential for much higher rates proves a promising future for CubeSat-scale laser communications."

The ISARA CubeSat developed by the Jet Propulsion Laboratory will study the performance of an integrated solar array and radio antenna and a compact suite of three visible and infrared cameras that could be employed on future weather satellites.

The Naval Postgraduate School's PropCube 2 CubeSat is also slated for deployment from Cygnus in December to measure disturbances in the ionosphere, an upper layer of Earth's atmosphere.

The Cost-effective High E-Frequency Satellite, or CHEFSat, from the Naval Research Laboratory will help engineers gauge the performance of a consumer-grade radio frequency device in space.

The first satellite for Asgardia, an organization that aims to become the first nation state in space, was also launched Sunday. The group was created by Igor Ashurbeyli, a Russian scientist, and the Asgardia 1 satellite hosts a 500-gigabyte solid state drive containing files and data uploaded by the organization's supporters, or citizens.

The Cygnus spacecraft will fall out of orbit in December after wrapping up the CubeSat deployments and burn up in the atmosphere over the South Pacific Ocean, discarding the space station's trash and other unneeded items tagged for disposal by NASA.

Orbital ATK is one of two NASA contractors with operational resupply vehicles for the space station.

The space agency awarded contracts to Orbital ATK and SpaceX in 2008 to ferry cargo to the research lab after the retirement of the space shuttle. Orbital originally received a $1.9 billion contract for eight missions, a deal that was later extended to 11 flights.

The current mission, known as OA-8, is the eighth flight in Orbital ATK's cargo resupply contract. NASA awarded Orbital ATK, SpaceX and newcomer Sierra Nevada Corp. a new round resupply contracts in 2016, guaranteeing each company a minimum of six more cargo missions from 2019 through 2024.

That puts Orbital ATK's backlog at at least nine more Cygnus resupply flights in the next seven years, most of which are expected to launch on the company's own Antares booster from Virginia. Orbital ATK also has the option to launch Cygnus missions using United Launch Alliance Atlas 5 rockets.

Хотя с другой стороны NASA LSP показывает для Антареса на 200 х 200 км и 38 градусов 6930 кг, а на 250 х 250 км и 51,6 градусов 6240 кг.

Спасибо за наводку, но тогда возникает новый казус. В миссии Cygnuc OA-5 корабль доставил на МКС 2425 кг при заявленной стартовой массе 6163 кг. Разница по доставляемому грузу на МКС - 913 кг, а по весу кораблей - 10 кг? Как понять этот парадокс?

Cygnus Open for Business; Crew Unloading New Bacteria, Plant and Tech Studies


The Cygnus spacecraft is pictured after it had been grappled with the Canadarm2 robotic arm by astronauts Paolo Nespoli and Randy Bresnik on Nov. 14, 2017.

The Expedition 53 astronauts are continuing to unload several thousand pounds of space cargo from the new Cygnus resupply ship that arrived Tuesday morning. Some of the new science cargo contains harmful bacteria for observation and CubeSats that will be deployed in Earth orbit.

Спойлер

The Cygnus is now installed on the Unity module and open for business. The astronauts entered the cargo craft Tuesday and started replenishing the station with almost 7,400 pounds of crew supplies, science experiments, spacewalk gear, station hardware and computer parts.

Some of the new research payloads will be looking at the space impacts on microbiology and botany. The advanced space research will explore the effectiveness of antibiotics on astronauts and observe how plants absorb nutrients in microgravity. Some dangerous germs delivered aboard Cygnus have also been safely transferred to the STaARS-1 Bioscience facility for later observation.

A couple of the newest technology experiments will deploy CubeSats to explore laser communications and hybrid solar panels. Scientists will study the ability of small satellites to communicate with each other using lasers and also explore if a combination of antenna and solar cells can speed up communication rates.

Если узнать массу служебного модуля "Лебедя" то можно самим вычислять вес корабля на основании доставляемого груза. Как я раньше писал, масса улучшенного Грузового герметичного модуля составляет - 1500 кг, а улучшенного - 1800 кг, топливо могут заливать вероятно не более 828 кг. У меня при расчетах миссий получаются следующие массы Служебного модуля: OA-4 -1351кг, ОА-6  - 1348 кг, ОА-5  - 1354 кг, ОА-7 - 1140 кг. Из следующего выводим среднюю массу СМ - 1350 кг. В миссии ОА-7 скорее всего было залито меньше топлива, в районе 600 кг или корабль удалось облегчить.
Если сложить ранее полученные данные то для миссии ОА-8 получим: (ГГМ -1800 кг) + (СМ - 1350 кг) + (доставляемый груз - 3338 кг) = 6488 кг. Это мы еще топливо не заливали. Так какой должен быть вес КК?

Cygnus Departure Preps as Muscle Study and CubeSat Ops Wrap Up

The Cygnus resupply ship is in its final week at the International Space Station and two astronauts are training for its departure on Monday. Meanwhile, a leg muscle study and CubeSat deployment operations are wrapping up today.

Cygnus is now being filled with trash after delivering close to 7,400 pounds of research and supplies to the Expedition 53 crew on Nov. 14. NASA astronauts Mark Vande Hei and Joe Acaba are training to release Cygnus from the Canadarm2 next week following a 20-day stay at the Unity module.

The duo will be inside the cupola commanding the Canadarm2 to release Cygnus back into Earth orbit on Dec. 4. Following its departure from the station, Cygnus will stay in orbit until Dec. 18 before re-entering the Earth's atmosphere for a fiery demise over the Pacific Ocean.
