It seems entirely fitting that a mission destined to ferry science cargo to the International Space Station (ISS) should be named for a deceased NASA astronaut who participated in the final dedicated science mission of the Space Shuttle Program. The name of veteran astronaut Kalpana “K.C.” Chawla—the first woman of Indian ancestry to voyage into space and a member of shuttle Columbia’s ill-fated STS-107 crew—was announced earlier this month and will be borne by Northrop Grumman Corp.’s NG-14 Cygnus cargo ship.

Launch atop an Antares 230+ booster is targeted for 10:26 p.m. EDT on Tuesday, 29 September from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, Va. It will arrive at the station on Saturday, 3 October, and is expected to spend two months there, before departing in mid-December and deorbiting at year’s end.

With only a few days remaining before “Space Ship Kalpana Chawla” takes flight, NASA hosted a media teleconference on Thursday afternoon (24 September) to outline the wide range of scientific investigations heading to the station. The Initial Cargo Load aboard Cygnus was completed last week, with Late Load operations wrapped up on Tuesday. There will be a final cargo load of time-critical experiments on Monday at Pad 0A, when Antares will be lowered to the horizontal configuration and a “pop-top” will afford technicians access to the spacecraft.

We completed the initial cargo load on September 16 and just completed late load on September 22. Cygnus is now undergoing fairing encapsulation in preparation for Antares to be rolled to the pad. Approximately 24 hours below launch we will do our final cargo load at the pad with the rocket horizontal.

As previously detailed by AmericaSpace, the launch will occur on the seventh anniversary of the first Cygnus arrival at the ISS and will be laden with a whopping 7,758 pounds (3,519 kg) of equipment, payloads and supplies to the station for the incumbent Expedition 63 and forthcoming Expedition 64 crews. This total includes 2,683 pounds (1,217 kg) of science investigations, 1,874 pounds (850 kg) of crew supplies, 2,712 pounds (1,230 kg) of vehicle hardware, 333 pounds (151 kg) of Extravehicular Activity (EVA) equipment and 156 pounds (71 kg) of computer resources.

Assuming an on-time launch, NG-14 will spend three days in transit, before it is robotically captured and berthed at the Earth-facing (or “nadir”) port of the station’s Unity node early on Saturday, 3 October. The capture will be led by Expedition 63 Commander Chris Cassidy, using the 57.7-foot-long (17.6-meter) Canadarm2 robotic arm, and will kick off more than two months of joint operations with the Cygnus. Cassidy will be backed-up in the station’s multi-windowed cupola by crewmate Ivan Vagner. Berthing of the spacecraft at Unity will be ground-commanded.

Current plans call for the spacecraft to be robotically unberthed on 16 December, after which it will spend two weeks in free flight, autonomously conducting the fifth set of Spacecraft Fire Experiments (SAFFIRE-V). Cygnus will then undertake a destructive re-entry into the atmosphere on 30 December, wrapping up its 92-day mission.

Provided by NASA’s Glenn Research Center (GRC) in Cleveland, Ohio, SAFFIRE seeks to safely examine the processes of combustion, smoke behavior and flame-spreading in the microgravity environment. Understanding fire behavior in space and how different materials propagate flames in the near-total absence of gravity carries profound implications for the development of future spacecraft.

Four previous SAFFIRE runs between July 2016 and May 2020 burned Solid Inflammatory Boundary at Low Speed (SIBAL) cloth—a cotton blend on a fiberglass substrate—as well as specimens of Plexiglas and Nomex.

SAFFIRE-V and the final member of the series, SAFFIRE-VI, which is currently targeted to launch aboard the NG-15 Cygnus next spring, will press the envelope by running their experiments at much lower pressures of about 8.2 psi and a 34-percent oxygen level, which is expected to increase the energetic vigor of the observed flames.

Another post-departure experiment aboard NG-14 is Northrop Grumman’s 71-pound (32 kg) SharkSat payload, a technology prototype to permit engineers to evaluate emerging technologies in the space environment. “SharkSat is a small payload that will mount to the Cygnus spacecraft, with a mission to collect telemetry data demonstrating the feasibility of new sensor and processing technologies in low Earth orbit,” Northrop Grumman’s Vicki Cox told AmericaSpace.

“Development timelines and lifecycles for space electronics are shrinking as missions are more rapidly evolving,” she continued. “This was an opportunity to bring in some innovation to our traditional processes and “experiment” with how we can quickly leverage robust commercial technology base, to meet these new mission timelines. SharkSat was a success in this regard demonstrating our capability and identifying future process alterations to further improve schedules.”

SharkSat will remain attached to Cygnus as a “hosted” payload. “It will not be powered on until Cygnus departs the ISS in mid-December and will operate for about two weeks,” Ms. Cox added. “We expect to collect telemetry data and performance information hopefully confirming performance on-orbit.”

Elsewhere aboard NG-14’s Pressurized Cargo Module (PCM) will be a multitude of science and technology experiments. The Plant Habitat-2 investigation, led by Dr. Karl Hasenstein of the University of Louisiana at Lafayette and provided by Techshot, Inc., of Exploration Park, Fla., will utilize the station’s Advanced Plant Habitat (APH) to cultivate radishes.

Over a 27-day growth cycle, the radishes’ metabolic and physiological behavior will be examined, as will their response to the space environment, as part of ongoing NASA efforts to sustain future astronauts on deep-space missions. Harvested radish specimens will be stored in the station’s Minus Eighty Degree Laboratory Freezer for ISS (MELFI).

A new station toilet, destined for installation in the Tranquility node and expected to be used on deep-space and lunar missions, will also ride into orbit aboard NG-14. The Universal Waste Management System (UWMS) will feed pre-treated urine into a regenerative system, which will recycle it into water for future use. At present, about 90 percent of all water-based liquids on the space station (including urine and sweat) are recycled, mimicking elements of Earth’s own water cycle to reclaim water from the air.

Sixty-five percent smaller and 40 percent lighter than the current ISS toilet, the UWMS features an automatic airflow start-up when the lid is raised, which is also expected to enhance odor control, and its ergonomic design should require less cleaning, maintenance and plumbing. Earlier this week, Chris Cassidy installed a cable for the UWMS.

Provided by Dr. Carlos Cabrera of the University of Puerto Rico, the Ammonia Electro-Oxidation Lab at the ISS (AELISS) experiment seeks to describe the electrochemical oxidation of ammonia in the microgravity environment, as part of efforts to advance long-term habitability aboard the space station through its water recovery capabilities. ALEISS also features collaboration from NASA’s Ames Research Center (ARC) in Moffett Field, Calif.

Elsewhere, Estée Lauder plans to photograph the company’s New Advanced Night Repair serum in the cupola “as part of NASA’s efforts to enable business activities at the space station”.

Other payloads include the ISS Experience EVA Camera to film a future spacewalk and Earth views in cinematic-quality, 360-degree virtual reality. According to NASA’s Dan Huot, a specific EVA has yet to be determined, with no spacewalks expected until after the arrival of Crew-1 astronauts Mike Hopkins, Victor Glover, Shannon Walker and Soichi Noguchi in late October. “It’s designed to be mounted on Canadarm2,” Mr. Huot told AmericaSpace. “Still waiting on what the final procedures will look like.” It may be carried outside by the astronauts and mounted in place or passed through the airlock of Japan’s Kibo lab.

AmericaSpace would like to thank Northrop Grumman’s Vicki Cox and NASA’s Dan Huot for their assistance in the preparation of this article.

    In the UK there is also a company that develops rockets for cargo delivery.The Skylark 1 launch vehicle will deliver payloads with a total weight of up to 60 kg to an altitude of just over 100 km. Its first launch into space is scheduled for spring 2021. Its first launch into space is slated for the spring of 2021.
