The overall goal of theThinSat-2mission, is to orbit small experiment payloads to advance STEM education,and promote space science research and systems engineering for grades 4 –12 and universities, from a number of states and the District of Columbia. The student teams will analyze the data collected by their experiment and submit a report detailing their findings.  The students will track their experiment and receive data in near real time through the Globalstar network and the Space Data Dashboard website.  Online content and resources will enhance the educational experience.

The experiments will be deployed aboard 9 satellites,ThinSat-2A through ThinSat-2I, launched as a secondary payload aboard the NG15 on the Antares second stage, from the mid-Atlantic Regional Spaceport, Wallops Island, Virginia, Q1 2021.  The satellites will be inserted into Low Earth Orbit (LEO), at 260km apogee and 180km perigee, on an inclination from the equator of 51.6degrees. They are deployed from 2 Canisterized Satellite Dispensers (CSDs) mounted on the second stage of the launch vehicle.  The ThinSats unfold accordion style as they exit the CSD.  Transmission will begin upon deployment, and cease within about a week, when de-orbiting occurs.See the Orbital Debris Assessment Report for details

I noticed to date Cygnus has not been named after any of the Challenger 51L crew members.
Any chance that will change with NG-15?

For the Cygnus vehicle itself, there is no planned object or debris release from Cygnus during
the mission, with exception of CubeSats or so call microsats. For the NG-15 mission, Cygnus
will deploy a number of CubeSats following departure from ISS. The external CubeSat Satellite
Deployer will be installed while berthed to ISS prior to departure from ISS by the NASA
Astronauts. Also a SEOPS SlingShot CubeSat deployer will be installed. The exact number of
CubeSats will be provided to the FCC when it becomes available. Each Deployer, with
integrated CubeSats, is provided to Orbital Sciences LLC by NASA and SEOPS. The CubeSats
release point will be approximately 45 km above the ISS. The Cygnus orbit will be circular at the
time of the deployments. Regulatory requirements including reentry debris assessment on
CubeSats are the responsibility of the CubeSat owner(s) and the respective providers, and are
not covered in this document.

Do we have any sources on if NG-15 is taking an additional crew quarter up for Hopkins / the 5th ISS crew member?

I remember Kenneth Todd talking about the timing and location of the CQ placement during a DM2 or Crew-1 press event but can't seem to find it.

I'd assume that Cygnus is the logical choice (vs Dragon) as the normal CQ is long and bulkier than a full rack. Would be interesting to see how they IKEA / flatpack the booth (especially with all the fans, air plenums and sound deadening chambers) or send up a modified one.

Thanks for all the good info! I'm not adding any value to this thread, but I've got to say I'd love to take the grandkids to see one of these launches at Wallops Island. We live in the northeastern USA, so it's accessible via car trip. It would be great to see a launch with a payload going to a particular destination. And the ISS is a place we can see for ourselves on a good night!

Northrop Grumman is proud to name the NG-15 Cygnus spacecraft after NASA mathematician Katherine Johnson, a Black woman who time and again broke through barriers of gender and race. It is a company tradition to name each Cygnus spacecraft after an individual who has played a pivotal role in human spaceflight. Her hand-written calculations were critical to America’s success during our first human spaceflight missions.

Science Launching on Northrop Grumman's 15th Resupply Mission
Quote
Experiments using worms to study muscle weakening, examining how astronauts sleep, and testing high-powered computers in space will be launching, along with more scientific experiments and supplies, to the International Space Station on a Northrop Grumman Cygnus spacecraft. This Cygnus is named the S.S. Katherine Johnson, after the NASA mathematician whose calculations were critical to the success of our early human spaceflight missions.

The vehicle launches no earlier than Feb. 20 from our Wallops Flight Facility in Virginia. Many of the experiments launching on this spacecraft build on previous studies conducted during the more than 20 years of continuous human habitation of the International Space Station, helping us explore farther in to space, and benefiting humans back on Earth.

SEOPS-3 / NG-15 TO LAUNCH THIS WEEKEND (https://spaceflight.com/seops-3/)
Quote
By Hilary Meyerson
FEBRUARY 16, 2021

Spaceflight works with a wide range of launch providers to get our customer satellites on orbit, but the satellites onboard Northrop Grumman’s Antares rocket are one of our more unique deployments.

Our next launch of this kind is targeted for 12:36 p.m. EST, Saturday, February 20, from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility, as the Antares will be delivering a resupply capsule, the Cygnus, to the International Space Station (ISS).

On board the Cygnus will be three spacecraft belonging to Spaceflight customers, including Gunsmoke-J and two undisclosed U.S. government payloads. The Gunsmoke-J is a Joint Capability Technology Demonstration executed by the U.S. Army Space and Missile Defense Command, sponsored by both the Office of the Under Secretary of Defense (Research and Engineering) and the U.S. Army. This science and technology effort will demonstrate an entry-level capability in a 3U form factor relevant to Army warfighter needs and will also help inform future acquisition decisions.

Per Gunter's page on Gunsmoke-J:

"Gunsmoke-J uses emerging advanced electronics to allow the use of dedicated intelligence assets to provide tactically actionable targeting data to warfighters on a responsive and persistent timeline."

Wow, gotta love the impenetrable English of defense sector bureaucrats :-)

So I translate that as "has an imaging payload that users can command directly and get images from"?? But I could be completely wrong...

Edit: completely wrong - rereading it and looking at the picture, it's a communications payload that sends the targeting
info from someone else to the user. So how is it different from the regular Prometheus? More bandwith, higher encryption?

Just had some email correspondence with Chris Hale of Va Space.
The 30 Thinsats are in 9 strings (i.e. 9 actual separate satellites)
They are deployed from two CSD dispensers.
He wasn't willing to give the full details but said this:
Our strings vary from 8 to 6 to 5-ThinSats (combo of 1T and 2T) to a single 6T payload, down to Single T “strings”.

The NG-15 Mission Profile Handout lists the  payload mass at 8,050 kg, heaviest Cygnus on an Antares, and apparently heavier than the Atlas 5 Cygnus payloads.

Cygnus Launch Mass:
8,050 kg (17,700 lb.)
Propellant Mass:
800 kg (1,764 lb.)
Ascent Cargo Mass:
Approx. 3,400 kg (7,500 lb.)

The NG-15 Mission Profile Handout lists the  payload mass at 8,050 kg, heaviest Cygnus on an Antares, and apparently heavier than the Atlas 5 Cygnus payloads.

Cygnus Launch Mass:
8,050 kg (17,700 lb.)
Propellant Mass:
800 kg (1,764 lb.)
Ascent Cargo Mass:
Approx. 3,400 kg (7,500 lb.)

 - Ed Kyle
Looking at this a bit more, I found that the NG-14 "Mission Profile Handout" had the same numbers!  I suspect that the actual liftoff mass was more like 7,700 kg, still a record for Antares, but I'm doing a lot of extrapolating to get that number.  The cargo mass for this mission was listed as 3,810 kg in the NASA handout.

Nanoracks Launches Two CubeSats on NG-15 Cygnus
 
Wallops Island, Virginia - February 22, 2021 – Earlier today, the NG-15 Cygnus spacecraft berthed with the International Space Station (ISS), carrying two CubeSats in the Nanoracks External Cygnus Deployer (E-NRCSD). The Cygnus arrived at the ISS after launching from Wallops Flight Facility Pad 0A on February 20, 2021 at 17:36 UTC. In celebration of Black History Month, the NG-15 Cygnus has been named in honor of Katherine Johnson, a NASA mathematician who had a vital role in early human space flight missions.

This launch is Nanoracks’ ninth mission providing opportunities for CubeSat deployment from the Cygnus. The CubeSats onboard today’s launch, IT-SPINS and MySat-2 (DhabiSat), were built by students and researchers at Montana State University and Khalifa University in Abu Dhabi.

The Cygnus will remain at the ISS for several weeks to complete its primary science and technology goals. After the Cygnus departs from the ISS, it boosts to a higher altitude, where the E-NRCSD dispenses the CubeSats into orbit.

The IT-SPINS CubeSat was selected for launch by NASA’s CubeSat Launch Initiative (CSLI) as part of the Educational Launch of Nanosatellites-33 (ELaNa-33) mission complement, sponsored by the NASA Launch Services Program (LSP).

MySat-2 (DhabiSat) is the second CubeSat built by Khalifa University to be launched by Nanoracks. MySat-1 was deployed from the NG-10 Cygnus spacecraft in February 2019. These small satellites enable students to design, implement and test software modules for attitude determination and control systems.

“It’s an amazing accomplishment to build and launch a satellite. It’s even more amazing that these CubeSat teams were able to do so in a time when working together has never been more difficult,” says Nanoracks Mission Manager Jake Cornish. “COVID-19 has caused us to rethink how to perform even normal tasks, so these individuals have accomplished something very special. We are extremely proud to work with groups who continuously push the boundaries of what’s possible, and we can’t wait to see what they come up with next.”

Nanoracks would like to thank Northrop Grumman and the NASA International Space Station Program for their continued support of Nanoracks’ operations on the ISS and throughout low-Earth orbit.

TOKYO (Reuters) - Myanmar’s first satellite is being held on board the International Space Station following the Myanmar coup, while Japan’s space agency and a Japanese university decide what to do with it, two Japanese university officials said.

The $15 million satellite was built by Japan’s Hokkaido University in a joint project with Myanmar’s government-funded Myanmar Aerospace Engineering University (MAEU). It is the first of a set of two 50 kg microsatellites equipped with cameras designed to monitor agriculture and fisheries.

...
The satellite was launched by NASA on Feb 20 as a small part of a large and varied payload of supplies to the International Space Station 400 km (250 miles) above the earth. It has since been kept by JAXA inside Japan’s Kibo experiment module.

Cygnus Resupply Ship Leaving Station Today Live on NASA TV

Mark Garcia Posted on June 29, 2021

About four months after delivering several tons of scientific experiments and supplies to the International Space Station, Northrop Grumman’s uncrewed Cygnus cargo spacecraft is scheduled to depart the orbiting laboratory Tuesday, June 29. This morning, flight controllers on the ground sent commands to use the Canadarm2 robotic arm to robotically detach Cygnus from the Earth-facing port of the Unity module and maneuver it into place.

Live coverage of the spacecraft’s release will air on NASA Television and the agency’s website, and the NASA app beginning at noon EDT, with its release from the robotic arm scheduled for 12:25 p.m.

NASA astronaut Megan McArthur will monitor Cygnus’ systems upon its departure from the space station.

The Cygnus resupply spacecraft is named after NASA mathematician Katherine Johnson, a Black woman who broke through barriers of gender and race, calculating orbital mechanics for some of the first U.S. human spaceflights.

Cygnus arrived at the International Space Station Feb. 22 with nearly 8,000 pounds of scientific investigations and supplies following a launch two days prior on Northrop Grumman’s Antares rocket from NASA’s Wallops Flight Facility on Wallops Island, Virginia. It was the company’s 15th commercial resupply services mission to the space station for NASA.

ISS Daily Summary Report – 6/28/2021

Cygnus Departure Preparations: The crew performed several activities in order to prepare Cygnus Northrup Grumman-15 (NG-15) for departure. The crew de-routed the Intermodular Ventilation (IMV) supply duct from Cygnus, closed the Cygnus hatch, reconfigured Common Berthing Mechanism (CBM) Controller Panel Assemblies (CPAs), and demated power and data connections in the Cygnus/Node 1 vestibule. Finally, the crew closed the Node 1 Nadir hatch and began depressurization of the Cygnus/Node 1 vestibule. NG-15 release is scheduled for Tuesday, June 29th at 11:15 AM CT.

Cygnus Departs Station After Four Month Mission

Mark Garcia Posted on June 29, 2021

At 12:32 p.m. EDT, flight controllers on the ground sent commands to release the Northrop Grumman Cygnus spacecraft from the Canadarm2 robotic arm after earlier detaching Cygnus from the Earth-facing port of the Unity module. At the time of release, the station was flying 270 miles over southern Wyoming.

The Cygnus spacecraft successfully departed the International Space Station four months after arriving at the space station to deliver about 8,000 pounds of scientific experiments and supplies to the orbiting laboratory.

After departure, Cygnus will remain in orbit to deploy five cube satellites, including the Ionosphere Thermosphere Scanning Photometer for Ion-Neutral Studies (IT-SPINS), which will add to researchers’ fundamental understanding of Earth’s Ionosphere, and the Khalifa University Students Satellite-2 (MYSat-2), which will train graduate students through the development and evaluation of its software.

Thursday evening Cygnus will perform a deorbit engine firing to set up a destructive re-entry in which the spacecraft, filled with waste the space station crew packed, will burn up in Earth’s atmosphere.

As one cargo spacecraft departs the station, another is preparing to launch and deliver more than 3,600 pounds of supplies. Beginning at 7 p.m., NASA Television, the agency’s website, and the NASA app will provide live coverage of the launch from the Baikonur Cosmodrome in Kazakhstan of Russia’s Progress 78 cargo spacecraft on a Soyuz 2.1a rocket at 7:27 p.m. (4:27 a.m. Wednesday, June 30, Baikonur time).

Northrop Grumman’s NG-15 Cygnus Spacecraft Departs International Space Station to Begin Secondary Mission

S.S. Katherine Johnson completes a four month stay at the station

DULLES, Va. – June 29, 2021 – Northrop Grumman Corporation (NYSE: NOC) announced today that its Cygnus spacecraft left the International Space Station to begin the next phase of the NG-15 mission. Cygnus was released by the station’s robotic arm at 12:32 p.m. ET, carrying more than 8,000 pounds of disposable cargo. Cygnus will remain in orbit for approximately three days to carry out the secondary phase of the mission.

The S.S. Katherine Johnson will now deploy five CubeSats via two separate CubeSat deployers, Slingshot and Nanoracks. This Cubesat deployment includes Dhabisat, the second CubeSat developed by Khalifa University in Abu Dhabi, United Arab Emirates. Dhabisat was developed as part of Khalifa’s Space Systems and Technology Concentration, a joint program developed in collaboration with UAE-based satellite operator Al Yah Satellite Communications Company (Yahsat) and Northrop Grumman.

“Our Cygnus cargo resupply missions to the International Space Station help enable humans to live and work in space,” said Frank DeMauro, vice president and general manager, tactical space systems, Northrop Grumman. “With each mission, we grow our capabilities beyond cargo resupply as we operate a high performing science laboratory for both civil and commercial companies during the secondary phase of our flight.”

The NG-15 Cygnus spacecraft was launched on Feb. 20 aboard Northrop Grumman’s Antares rocket, carrying nearly 8,000 pounds of scientific research, supplies and equipment to the astronauts living on the station. The vehicle has been berthed with the orbiting laboratory since Feb. 22.

Nanoracks Ninth CubeSat Deployment Mission From the Cygnus.

JUNE 30, 2021

HOUSTON, TX – JUNE 30, 2021 – At 22:50 UTC yesterday, two Nanoracks customer CubeSats were deployed from the Nanoracks External CubeSat Deployer (E-NRCSD) on the Northrop Grumman Cygnus spacecraft. After a four-month mission to the International Space Station (ISS), the NG-15 Cygnus, named the S.S. Katherine Johnson, unberthed from the ISS and boosted into a higher orbit to deploy the CubeSats.

The two CubeSats, IT-SPINS and MySat-2, were released into a circular orbit about 490 km (304 miles) above the Earth’s surface.

The Ionospheric-Thermospheric Scanning Photometer for Ion-Neutral Studies (IT-SPINS) CubeSat was built by Montana State University and selected for launch by NASA’s CubeSat Launch Initiative (CSLI) as part of the Educational Launch of Nanosatellites-33 (ELaNa-33) mission complement, sponsored by the NASA Launch Services Program (LSP). The mission provides the first two-dimensional (2D) tomographic imaging from a 3U CubeSat to better understand the basic nature of the nocturnal ionosphere. This research strengthens fundamental understanding for development of ion gradient structures in the topside of the Earth’s ionosphere.

MySat-2 (also known as DhabiSat) was built by Khalifa University in Abu Dhabi, UAE and is the second Khalifa University CubeSat to be launched by Nanoracks. The first, MySat-1, was deployed from the NG-10 Cygnus spacecraft in February 2019. These small satellites enable students to design, implement and test software modules for attitude determination and control systems.

Nanoracks would like to thank Northrop Grumman and the NASA International Space Station Program for their continued support of Nanoracks’ operations on the ISS, the Cygnus spacecraft, and throughout low-Earth orbit.

For additional updates, follow @Nanoracks on Twitter. For media inquiries, please contact D’Mani Harrison-Porter, [email protected].

Space Weather Focused ELaNa CubeSat Deploys from Cygnus Spacecraft

Danielle Sempsrott Posted on July 1, 2021

The sole CubeSat of the 33rd Educational Launch of Nanosatellites (ELaNa) mission was deployed into space at 6:50 p.m. EDT June 29 from Northrop Grumman’s Cygnus spacecraft hours following its departure from the International Space Station.

The CubeSat, Ionosphere-Thermosphere Scanning Photometer for Ion-Neutral Studies (IT-SPINS), was stowed within the Nanoracks CubeSat Deployer (eNRCSD) mounted on the exterior of the S.S. Katherine Johnson Cygnus spacecraft. Once the Cygnus departed the space station, it remained in orbit to deploy a total of 5 cube satellites, including IT-SPINS, which was deployed into a free-flying orbit at an altitude between 304 and 210 miles (490 and 500 kilometers) above Earth’s surface.

This mission aims to improve space weather forecasting related to dynamic processes in Earth’s ionosphere. The 3U CubeSat is equipped with a sensitive photometric instrument to remotely sense ultraviolet emissions produced when oxygen ions combine with electrons in the ionosphere. This investigation plans to reveal the dynamics of a physical boundary region in Earth’s ionosphere where the oxygen-dominated ionosphere becomes proton dominated with increasing altitude, in a layer known as the Topside Transition Region (TTR).

IT-SPINS launched aboard Northrop Grumman’s 15th NASA contracted cargo resupply mission to the International Space Station from Wallops Flight Facility in Virginia on February 20.

IT-SPINS is the twelfth in a series of CubeSats developed by Montana State University’s Space Science and Engineering Laboratory to advance CubeSat capabilities and conduct scientific investigations to answer question in the Geospace sciences. This mission is sponsored by the National Science Foundation, which has supported it during its development and is supporting the beginning of operations. IT-SPINS was selected by NASA’s CubeSat Launch Initiative (CSLI), which is managed by NASA’s Launch Services Program (LSP) based at Kennedy Space Center. Since its inception in 2010, CSLI has selected 202 CubeSat missions from 42 states, the District of Columbia, and Puerto Rico, and 119 CubeSat projects have launched into space through ELaNa rideshare opportunities.
