Launch Time
Sat Aug 3, 2024 18:28 GMT+3
Due to the retirement of the Antares 230+ rocket, Northrop Grumman purchased three missions from SpaceX to launch the Cygnus spacecraft to the International Space Station before the Antares 330 rocket enters operation and fulfill the CRS Phase 2 contract manifest.

Mission Details
CRS NG-21
Cygnus NG-21 (Northrop Grumman-21) is a cargo resupply mission of the Northrop Grumman Cygnus spacecraft to the International Space Station under the Commercial Resupply Services (CRS) contract with NASA.
Northrop Grumman and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station. The Cygnus cargo ship consists of two parts, a service module built in the USA based on the GEOStar platform, and a pressurized module, manufactured in France and Italy by Thales Alenia.
Payloads: 1  Low Earth Orbit

Location
SLC-40, Cape Canaveral SFS, Florida, USA

The next cargo mission to resupply the residents living and working aboard the International Space Station is counting down to a launch at 11:28 a.m. EDT on Saturday from Kennedy Space Center in Florida. Northrop Grumman's Cygnus space freighter will launch atop a SpaceX Falcon 9 rocket carrying 8,200 pounds of science, supplies, and hardware for the station. Cygnus will orbit Earth for just over a day-and-a-half before approaching the orbital outpost where the Canadarm2 robotic arm will be waiting to capture the spacecraft.

NASA Flight Engineers Matthew Dominick and Jeanette Epps spent Monday preparing for Cygnus' arrival reviewing its mission profile and practicing robotic capture maneuvers on a computer. Dominick will command the Canadarm2 to capture Cygnus at 5 a.m. on Aug. 5 while Epps backs him up and monitors the approach and rendezvous activities. Afterward, robotics controllers on the ground will remotely take over Canadarm2 and guide Cygnus toward the Unity module's Earth-facing port where it will be mated for five-and-a-half months.

Почему при переходе с Антареса на Ф9 грузоподъемность Цигнуса не увеличилась?

Почему при переходе с Антареса на Ф9 грузоподъемность Цигнуса не увеличилась?

Может потому что цигнус был уже сделан?

NASA, Universities to Study Earth's Soil, Use New Technology in Orbit

NASA's CubeSat Launch Initiative soon will send two CubeSats to the International Space Station as cargo on the 21st Northrop Grumman commercial resupply mission.
CySat-1, designed and built by students from Iowa State University, measures Earth's soil moisture content from low Earth orbit. The measurements will be taken with a software-defined radiometer, a system that uses software to process analog radio signals. Students will create computer programs to analyze those signals to determine levels of moisture in the soil present on the Earth. As Iowa State University's first CubeSat, CySat-1 will be a technology demonstrator for future CubeSat missions.
Students at Arizona State University and NASA's Jet Propulsion Laboratory (JPL) in Southern California developed DORA (Deployable Optical Receiver Aperture), a new technology CubeSat.
In the past, small satellites required precision pointing and only achieved low data transmissions in gathering information. The technology will demonstrate new optical communications without precision pointing and use a solid-state photon detector to gather high data rates using wide-field optical receivers. To test the detector's performance, DORA will measure the background light from reflected sunlight, moonlight, and city lights when deployed from the space station into low Earth orbit.
The two demonstrations, CySat-1 and DORA, are both 3U CubeSats, a class of small satellites. The cube-shaped spacecraft are sized in standardized units, or Us, typically up to 12U. One CubeSat unit is defined as a volume of about 10x10x10 cm in size and typically weighs less than 2 kilograms.
The satellites will be released from the International Space Station using the Nanoracks CubeSat Deployer. One of the space station's arms grabs and points the deployer in the proper direction to release the CubeSats into orbit.
Launch of the Cygnus spacecraft is targeted at 11:28 a.m. EDT Saturday, Aug. 3, on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

ПН - грузовой корабль Cygnus от Northrop Grumman с 21-й миссией на МКС в интересах NASA. Корабль носит имя бывшего астронавта NASA Фрэнсиса Скоби.
Cygnus доставит на станцию 3719 кг различных грузов, в т.ч. материалы для исследований стволовых клеток, тканей печени, эксперименты по оценки влияния космического полёта на ДНК микроорганизмов, испытания технологии извлечения воды, студенческие эксперименты и кубсаты для последующего запуска с борта станции.
Корабль Cygnus находится под модифицированным обтекателем грузовой версии ракеты Falcon 9. В нём сделан люк размером 1,5 на 1,2 м, который можно открыть, чтобы обеспечить возможность поздней загрузки грузов в корабль непосредственно на стартовой площадке. При этом возможность спасения такой створки обтекателя сохраняется.
Место старта - SLC-40, Флорида
Ракета - Falcon 9 FT Block 5
— Первая ступень - B1080 (10-й полёт)
Возвраты:
— Посадка первой ступени на площадку LZ-1
— Cпасение створок головного обтекателя в 498 км

Интересно, повезут ли на нём кресла для возможного возвращения экипажа Старлайнера на Драконе

Нет, не повезут. На телеконференции по NG-21 сказали. Вряд ли такой вариант вообще рассматривался. Гораздо проще  запустить Crew-9 полупустым, оставив Суни и Буча до февраля.

Aboard the Cygnus spacecraft are tests of water recovery technology, a process to produce stem cells in microgravity, studies of the effects of spaceflight on microorganism DNA, liver tissue growth, and live science demonstrations for students.
