Northrop Grumman names each Cygnus spacecraft in honor of individuals who have made substantial contributions to the United States’ commercial space program and human space flight. The NG-14 mission commemorates Kalpana Chawla, a NASA astronaut and the first woman of Indian descent to fly in space. Chawla was selected for the astronaut program in 1994, with her first flight in 1997 on STS-87 aboard the Space Shuttle Columbia. In 2003, Chawla and her crew members tragically lost their lives during mission STS-107 when Columbia did not survive its return to Earth. 2)

Born in Haryana, India, Chawla moved to the United States to earn her master's and doctorate degrees in aerospace engineering from the University of Texas in 1984 and University of Colorado in 1988, respectively. She then began her career at NASA, conducting research in fluid dynamics at the Ames Research Center in California.

Kalpana Chawla," in memory of the mission specialist who died with her six crewmates aboard the space shuttle Columbia in 2003.Kalpana Chawla was the first Indian-born woman and NASA astronaut to fly into space (image credit: Northrop Grumman/NASA/collectSPACE.com) 3)

After becoming a naturalized U.S. citizen, Chawla applied for and became a NASA astronaut as a member of "The Flying Escargot," NASA's 15th class of trainees. In 1997, she launched on STS-87, a 15-day shuttle mission that was dedicated to the science flying as part of the fourth United States Microgravity Payload (USMP-4).

Chawla's second spaceflight, STS-107, came to a tragic end on Feb. 1, 2003, following 16 days of conducting science on board the space shuttle Columbia. A small piece of foam that struck the orbiter's left wing during launch created a hole that went undetected during the mission. Upon Columbia's return to Earth, hot plasma entered the wing, tearing it apart, and the resulting loss of control led to the vehicle disintegrating and the death of the crew.

The launch was originally scheduled for Sept. 29 but delayed two days by weather. A launch attempt on Oct. 1 was aborted a little more than two and a half minutes before liftoff because of a problem with software in ground systems.


The Cygnus spacecraft SS Kalpana Chawla is scheduled to arrive at the space station Monday, Oct. 5. Expedition 63 Commander Chris Cassidy of NASA will grapple Cygnus and Flight Engineer Ivan Vagnerof Roscosmos will act as a backup. After Cygnus capture, mission control in Houston will send ground commands for the station’s robotic arm to rotate and install it on the bottom of the station’s Unity module. Cygnus is scheduled to remain at the space station until mid-December, when it will depart the station. Following departure, the Saffire-V experiment will be conducted prior to Cygnus deorbit and disposing of several tons of trash during a fiery re-entry into Earth’s atmosphere approximately two weeks later.

The Northrop Grumman Cygnus spacecraft was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 8:01 a.m. EDT while the spacecraft were flying about 261 miles above the South Pacific Ocean. Cygnus will remain at the space station until its departure in mid-December. Following departure, the Saffire-V experiment will be conducted prior to Cygnus deorbit and disposing of several tons of trash during a fiery re-entry into Earth’s atmosphere approximately two weeks later. 5)

Some Experiments and Payloads

On the NG-14 mission, the S.S. Kalpana Chawla delivered nearly 3,600 kg of food, supplies and experiment hardware for astronauts living on the International Space Station.

- Crew supplies: 850 kg

- Science investigations: 1,217 kg

- Spacewalk equipment: 151 kg

- Vehicle hardware: 1,230 kg

- Computer resources: 71 kg


Multi-Needle Langmuir Probe (m-NLP) instrument from the University of Oslo and the Norwegian company Eidsvoll Electronics to measure ionospheric plasma densities. With its relatively low orbit, the International Space Station (ISS) passes near the peak plasma density of the ionosphere. The m-NLP is currently the only instrument in the world capable of resolving ionospheric plasma density variations at spatial scales below one-meter. m-NLP will be the first payload to be installed on the Bartolomeo platform outside the European Columbus module.

ELaNa 31, Educational Launch of Nanosatellites, will deploy the following CubeSats from ISS: BobCat-1, a 3U CubeSat of Ohio State University, Columbus, Ohio; NEUTRON-1 (Neutron Flux Detection and COSMOS Mission Operations Technology Demonstration), a 3U CubeSat of the University of Hawaii at Manoa, and SPOC (Spectral Ocean Color) satellite, a 3U CubeSat of the University of Georgia, Athens, GA.

Saffire-V (Spacecraft Fire Experiment-V), flying its fifth (and second-to-last) mission, provided by NASA's Glenn Research Center (GRC) in Cleveland, Ohio, safely examines the process of combustion, smoke behavior and flame-spreading in the microgravity environment. The last two Saffires will run at much lower pressures of around 8.2 psi and a 34% oxygen level. These represent significantly higher atmospheric conditions than are found here on Earth and this is expected to increase the energetic vigor of their respective flames. David L. Urban, Ph.D. of the NASA Glenn Research Center in Cleveland, Ohio is the principal investigator for this experiment series. 6)

Further research flying aboard the Cygnus includes (Ref. 1): 7)

Improving how we ‘go’ in space: A new toilet is headed to the space station. Its features improvement on current space toilet operations and help NASA prepare for future missions, including those to the Moon and Mars. The Universal Waste Management System (UWMS) demonstrates a compact toilet and the Urine Transfer System that further automates waste management and storage. The smaller footprint of the UWMS supports a possible increase in the number of crew members aboard the space station, as well as planning for future exploration missions.

Energy and water from waste: The investigation Elucidating the Ammonia Electrochemical Oxidation Mechanism via Electrochemical Techniques at the ISS (Ammonia Electrooxidation) examines a process for ammonia oxidation in microgravity. An electrochemical ammonia removal system could serve as an innovative water recovery system on long-duration missions to the Moon and Mars and provide vital drinkable water in remote and arid areas on Earth.

Adding radishes to the space salad: A new crop of vegetables is headed to the space station. While previous experiments have grown different types of lettuces and greens aboard the orbiting laboratory, the Assessment of Nutritional Value and Growth Parameters of Space-grown Plants (Plant Habitat-02) investigation adds radishes to the mix, cultivating seeds to see how different light and soil conditions affect growth. Findings could help optimize growth of the plants in space, as well as provide an assessment of their nutrition and taste.

Identifying targeted cancer treatments: The Leveraging Microgravity to Screen Onco-selective Messenger RNAs for Cancer Immunotherapy (Onco-Selectors) investigation tests drugs based on messenger ribonucleic acids(mRNA)for treating leukemia. In normal gravity, the drugs to be tested are onco-selective, meaning they can distinguish cancer cells from healthy ones. Researchers expect any drugs that also demonstrate this trait in microgravity could make good candidates for safer, more effective, and affordable medicines to treat leukemia and other cancers. This could improve survival rates for thousands of people every year.

Spacewalks in VR (Vvirtual Reality): The International Space Station Experience (ISS Experience)is creating an immersive virtual reality series documenting life and research aboard the space station. Partnering with the ISS National Lab and TIME, a team from Felix and Paul Studios launched a customized 360-degree camera to the space station in December 2018that crew members have used to record a few hours inside the station every week. Felix and Paul and partner NanoRacks further modified an additional camera to withstand the extreme conditions of space and are launching for use in filming a spacewalk. The new camera will be mounted to the Canadarm2to capture a spacewalk from start to finish as well as footage of Earth and the exterior of the space station.

These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars through NASA's Artemis program.
