NASA WALLOPS FLIGHT FACILITY, VA –  Everything remains on track for this week’s launch of Northrop Grumman’s next private Antares rocket hauling the company’s next unpiloted commercial Cygnus cargo ship loaded with almost 4 tons of science and supplies to the International Space Station (ISS) from NASA’s Wallops Flight Facility along Virginia’s Eastern Shore on Wednesday, April 17.

40 micetronauts are also loaded aboard Cygnus for the first time as a result on upgraded capabilities introduced for the first time this mission.


The weather outlook is excellent and large crowds are expected for the sure to be spectacular overnight blastoff Wednesday afternoon. 

NASA’s commercial partner Northrop Grumman is scheduled to launch its Antares rocket in the upgraded 230 configuration carrying its Cygnus cargo spacecraft to the International Space Station at 4:46 p.m. EDT (2046 GMT) Wednesday, April 17 from seaside Launch Pad 0A at the Virginia Space Mid-Atlantic Regional Spaceport (MARS) at NASA’s Wallops Flight Facility in Virginia.

In anticipation of a launch, Northrop Grumman workers rolled Antares to the launch pad Monday morning April 15, approximately 1 mile (1.6 km) from the Horizontal Integration Facility (HIF) to pad 0A at Wallops. 

The Cygnus NG-11 commercial resupply cargo ship is loaded with nearly 7,600 pounds (3,440 kilograms) of science experiments, research, gear, crew supplies and hardware, for Northrop Grumman’s 11th commercial resupply NASA-contracted mission. 

About two-and-a-half hours after launch, an automated command will initiate deployment of the spacecraft’s solar arrays. Full deployment will take approximately 30 minutes.

Check out our Space UpClose gallery of launch pad imagery with the rocket both vertical and horizontal as workers completed the stocking of ‘late load’ items starting Tuesday evening.  

The countdown will begin 5 hours before launch at 11:46 a.m. ET (1546 GMT). 

You can watch the launch live on NASA TV and the agency’s website.

The launch window opens at 4:46 p.m. EDT and extends for 5 minutes total until 4:51 p.m. EDT. 

Launch coverage and commentary on NASA TV  and streaming online at nasa.gov/live will begin at 4:15 p.m. EDT April 17.  The agency will air the launch as well as briefings preceding and following liftoff on NASA Television.  

Weather permitting the Antares launch will be visible to tens of millions of residents in along the US Easy Coast especially in the Atlantic and Northeast regions. 

“The launch may be visible, weather permitting, to residents up and down the East Coast of the United States,” says NASA.

And superb weather conditions are forecast for April 15 with a 95% chance of favorable conditions. 

Here is a visibility map from NASA:

In a significant upgrade to Cygnus capabilities, Northrop Grumman is introducing the capability to add ‘late load’ items - such as allow time-sensitive science experiments. For the first time these late load items will be loaded into Cygnus just 24 hours before liftoff.

This is being demonstrated for NG-11. After rolling out Monday, the rocket was lowered Tuesday evening around 5 p.m. ET during our media remote camera setup.

Technicians then moved the mobile clean room snugly up to the Cygnus nose cone and open it via the newly added ‘pop top’ 

‘Approx. 140 kg of late load items are being added and it will take about 7 hours to complete the task of stocking Tuesday evening through about midnight and raise the rocket back to vertical,’ Frank DeMauro, Vice President and General Manager, Space Systems, Northrop Grumman, told Space UpClose. 











Previously, all cargo had to be loaded about four days prior to launch. This new capability enabled the addition of the 40 mice for the first time ever to Cygnus  for example. 








Last fall Space UpClose took an exclusive UpClose tour of this NG-11 rocket and the last one NG-10 as the two Antares rockets being processed side by side inside the Northrop Grumman rocket assembly factory at Wallops known as the Horizontal Integration Facility (HIF).

Cygnus will deliver vital equipment, supplies and scientific equipment to the space station as part of Northrop Grumman’s Commercial Resupply Services-1 (CRS-1) contract with NASA – totaling 11 cargo flights.

“NG-11 is the mission under the CRS-1 contract,” said Kurt Eberly Antares vice president at Northrop Grumman.   NG-10 last fall was the “next to last.” 

Here are some highlights of space station research that will be facilitated by investigations aboard this Cygnus - from NASA:

·        Advanced Colloids Experiment-Temperature-10 (ACE-T-10) investigates the growth, microscopic dynamics, and restructuring processes in ordered and disordered structures such as colloidal crystals, glasses, and gels. Colloids provide ideal models for researching the fundamental principles of internal organization in such structures because their particles are small enough to engage in relevant phenomena, yet large enough for detailed study. Colloidal system interactions vary precisely with temperature and undergo a variety of transitions including crystallization and glass formation. Conducting the study in microgravity removes the effects of gravitational stresses.


·        Bio-Analyzer, a Canadian Space Agency (CSA) instrument, enhances life sciences research capabilities on the space station. It performs on-orbit detection and quantification of cell surface molecules on a per cell basis, including blood cell counts, and assesses soluble molecule concentration in a liquid sample such as blood, saliva, or urine. Part of the Life Science Research System (LSRS), the Bio-Analyzer uses just a few drops of liquid – a finger prick versus a standard blood draw, for example – and eliminates the need for freezing and storing samples.


·        Recent research suggest links between cardiovascular health risk, carotid artery aging, bone metabolism and blood biomarkers, insulin resistance, and radiation. Data also indicate accelerated aging-like changes in many astronauts on the space station, including changes to their arteries. The Space Environment Causes Acceleration of Vascular Aging: Roles of Hypogravity, Nutrition, and Radiation (Vascular Aging) looks at these changes using artery ultrasounds, blood samples, oral glucose tolerance tests, and wearable sensors. It is one of three related Canadian experiments studying the effects of weightlessness on the blood vessels and heart.


·        A small robot takes on big jobs aboard the space station. The free-flying Astrobee can help scientists and engineers develop and test technologies for use in microgravity, give astronauts a hand with routine chores, and provide additional eyes and ears for flight controllers in Houston.


·        Building on the success of SPHERES, NASA’s first-generation free-flyer, Astrobee, operates either in fully automated mode or under remote control from the ground. It can run longer and requires no supervision from the crew, freeing up more astronaut time for research. It also opens up more opportunities to experiment and test capabilities with lower risk. Astrobee is a product of the NASA Game Changing Development Program.

The Cygnus spacecraft, dubbed the SS Roger Chaffee, will arrive at the space station Friday, April 19. At about 5:30 a.m., Expedition 59 NASA astronaut Anne McClain will grapple the spacecraft using the station’s robotic arm. She will be backed up by David Saint-Jacques of the Canadian Space Agency. NASA astronaut Nick Hague will monitor Cygnus systems during its approach. After capture, ground controllers will command the station’s arm to rotate and install Cygnus on the bottom of the station’s Unity module.
Live coverage of the grapple will begin at 4 a.m. and Cygnus installation coverage will begin at 7 a.m. April 19.

The Cygnus spacecraft is scheduled to remain at the space station for about 3 months until July 23, 2019, when it will depart the station, deploy NanoRacks customer CubeSats, and then have an extended mission until December 2019 before it will dispose of several tons of trash during a fiery reentry into Earth’s atmosphere.

This will be the final mission under Northrop Grumman’s CRS-1 contract with NASA before starting the CRS-2 contract missions in the fall of 2019. Under Northrop Grumman’s Commercial Resupply Services contract, the company will fly 11 missions.
