Antares to Launch NG-11 Cygnus from VA April 17, Honors Apollo 1 Hero Roger Chaffee « AmericaSpace

Roger Chaffee never received to fly in area. Selected by NASA as a member of the area company’s third group of astronauts—alongside future Moonwalkers Al Bean, Buzz Aldrin, Dave Scott and Gene Cernan—he was the youngest of his class and in March 1966 drew his first plum flight task as pilot of the first manned Apollo mission. Sadly, ten months later, on the evening of 27 January 1967, he and crewmates Virgil “Gus” Grissom and America’s first spacewalker, Ed White, have been killed in a flash hearth aboard their Apollo 1 command module. Chaffee was three weeks shy of his 32nd birthday.

Greater than a half-century later, on Wednesday, 17 April, the Navy lieutenant-commander will fly in identify at the least to the International Area Station (ISS), when Northrop Grumman Innovation Techniques—formerly Orbital ATK and, earlier than that, Orbital Sciences Corp.—launches the NG-11 Cygnus cargo ship atop an Antares 230 booster from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Va. Laden with 7,500 pounds (Three,400 kg) of experiments, gear and provides for the incumbent Expedition 59 crew, the “Spaceship (SS) Roger Chaffee” will strategy and berth at the area station early Friday, 19 April, with astronauts Anne McClain of NASA and David Saint-Jacques of the Canadian Area Agency (CSA) at the controls of the 57.7-foot-long (17.6-meter) Canadarm2. Monitoring Cygnus’ techniques in the course of the strategy can be fellow Expedition 59 crewman Nick Hague. In accordance to the schedule, McClain will grapple the cargo ship at 5:30 a.m. EDT, whereupon floor controllers will command Canadarm2 to rotate and set up Cygnus onto the Earth-facing (or “nadir”) port of the station’s Unity node.

NG-11 will exhibit, for the primary time, the power to “late-load” cargo aboard the spacecraft, just 24 hours prior to launch. It will permit for time-sensitive payloads, together with the reside rodents aboard NG-11, to be safely transported to the ISS. Beneath the processing regime for previous Cygnus missions, the final cargo was loaded about 4 days before launch, with the car rolled out to the pad at L-2. On 11 April, Northrop Grumman introduced that Cygnus was fueled and its initial cargo load had been accomplished, ahead of encapsulation in the Antares payload fairing and rollout to Pad 0A at MARS.

“An area of high pressure will press down from the Northeast states Wednesday morning, forcing a backdoor cold front through the Wallops Region to shift surface winds out to a northeasterly component for the launch window,” noted Wallops’ L-2 climate briefing on Monday. “A weak upper-level disturbance within the northwesterly upper-level flow will track towards the Mid-Atlantic Wednesday to increase upper-level cloudiness.” All advised, this presents an 85 % chance of acceptable circumstances for an on-time launch on Wednesday, 17 April, tempered by a danger of extreme ground winds and thick clouds.

As detailed by Northrop Grumman, the late-load functionality is made attainable by way of a specialized detachable nose cone—nicknamed a “pop-top”—and cellular payload processing facility. “For late-load operations, Antares will roll to the pad four days before launch and mate all connections needed for launch, except for the liquid oxygen loading line,” the company explained. “The team will then raise Antares to its vertical launch position and perform a full combined systems test to verify all systems are working properly. Once all the pre-launch testing is complete, operators will lower Antares to a horizontal position, maneuver the mobile payload processing facility over the front of the fairing and seal the opening to provide a cleanroom environment. The team will then put platforms in place, remove the pop-top from the nose cone, open the Cygnus hatch and load the final time-sensitive cargo. After completing the late-load, operators will close the hatch, remove the mobile payload processing facility, raise Antares to vertical again and make all final ground connections in preparation for launch.”

In feedback offered to AmericaSpace by Northrop Grumman’s Vicki Cox, it has grow to be traditional to identify every Cygnus “after an individual who has made a significant impact on the aerospace industry”. The eleven previous Cygnus missions—ten “operational” flights and the ORD-D shakedown check, back in September 2013—all honored quite a lot of spaceflight luminaries: former shuttle flyers G. David Low, Janice Voss, Alan “Dex” Poindexter, Rick Husband and Gordon Fullerton; Moonwalkers John Young and Gene Cernan; and Challenge Mercury astronauts Deke Slayton and John Glenn. Nevertheless, Chaffee and former NASA Deputy Administrator James “J.R.” Thompson are the only Cygnus honorees who by no means flew to area.

“Although Chaffee never made it to space, his sacrifice inspired fellow and future astronauts to push the boundaries of spaceflight,” the Northrop Grumman comments continued. “In the 50 years since the Apollo 1 crew’s tragedy, Americans have visited the Moon, built a home on the International Space Station and begun to plan extended trips through deep space to Mars.”

Wednesday’s flight of NG-11 would be the eighth mission by an “Enhanced” Cygnus, which first flew again in December 2015. It benefits from a “stretched” Pressurized Cargo Module (PCM), which is capable of carrying a 60-percent larger haul of payloads than its predecessor, the Normal Cygnus, which flew the initial missions till October 2014. Combined with its service module, the Enhanced Cygnus stands 15.9 ft (4.86 meters) tall and 10.1 ft (3.07 meters) in diameter and may home a payload quantity of 950 cubic ft (27 cubic meters). It’s visually distinctive from the Commonplace Cygnus in that the improved model boasts fan-shaped low-mass Ultraflex gallium arsenide photo voltaic arrays. It may possibly also help up to 90 days of berthed operations at the ISS and up to a yr in area.

Indeed, this extended-duration independent-flight functionality shall be trialed for the primary time on NG-11, for Area Ship Roger Chaffee is scheduled to unberth from the station in July and conduct several months in free flight, before it is destructively deorbited in December. Though a number of earlier Cygnuses have loitered in low-Earth orbit for up to a couple of weeks after departing the ISS—to conduct autonomous investigations, together with the Spacecraft Hearth Experiment, or Saffire—NG-11 will achieve this for much longer.

Assuming it berths on the station as scheduled on Friday, 19 April and unberths as scheduled on 23 July, the mechanized Roger Chaffee will log a record-setting 95 days hooked up to the ISS, eclipsing the previous record-holder, the NG-10 SS John Younger, which ended its mission in February after 81 days’ berthed time. It remains to be seen exactly how long NG-11 will stay in autonomous free-flight, nevertheless it appears possible that it’ll eclipse the 100 days’ complete time in area recorded by its fast predecessor, NG-10.

The NG-11 mission will close out the first part of the Business Resupply Providers (CRS1) contract, signed between NASA and Orbital Sciences Corp., method back in December 2008. This initially referred to as for eight dedicated Cygnus missions, however with the elevated uplift afforded by a pair of Atlas V launches and the larger payload envelope of the Enhanced Cygnus, this target was surpassed before meant. Following the completion of an “extension” program, bridging the gap between the top of CRS1 and the start of the CRS2 part—for which contracts have been signed back in January 2016—it is expected that the NG-12 Cygnus mission, slated to launch late in 2019, will kick off the second part of Business Resupply Providers, lasting via 2024.

The selection of Roger Chaffee as this mission’s namesake is particularly timely. “In terms of the Chaffee choice, we tied it to the 50th anniversary of the Apollo 11 Moon landing this year,” Ms. Cox informed AmericaSpace. “Chaffee had died just two years earlier in 1967—tragically—during that simulated launch of the Apollo 1 mission. Although his teammates had flown in space earlier, he never got the chance. We see Cygnus as a visible reminder of all that he did to pave the way for his fellow astronauts on that epic voyage to the Moon and all of the milestones that came after that. He made the ultimate sacrifice and we are proud to fly in his honor.”

For as Chaffee himself as soon as remarked: “There’s a lot of unknowns and a lot of problems that could develop and have to be solved. And that’s what we’re there for. This is our business.”

The writer would really like to categorical honest appreciation to Ms. Vicki Cox, Director of Communications for Northrop Grumman Innovation Techniques, for her time in responding to questions for this preview function.
