The overall goals of the RHOK-SAT mission are educational and scientific. The educational (primary) objective is to give students hands-on learning on the mechanical, software, and RF engineering involved with satellite development. Our students engaged public high schools, museums, and STEM related programs to teach students about the solar system and satellite orbits as part of an outreach curriculum. Its scientific (secondary) objective is to collect data on perovskite solar cells and assess their hardiness in orbit over time.The satellite will be launched to the ISS as cargo on the NG-22 resupply mission
The DUPLEX mission, a 6U cubesat, is currently licensed under file 0048-EX-CN-2023. A modified license is requested to reflect the following changes to the mission: 1. It will still deploy from the ISS, but it will be carried to the ISS on a later vehicle, NG-22 instead of SpX-28, No Earlier Than February 1, 2025.
The satellite will be launched as a secondary payload aboard CRS NG-22 ISS cargo re-supply mission, from Cape Canaveral, Florida on June 7, 2025.The spacecraft is a single unit with the dimensions of a 1U 10 cm X 10 cm X 11.35 cm CubeSat module. The total mass is about 883 g
Our mission concept employs a 1U CubeSat that takes photos of Earth, and when in contact with a ground station, directly logs into Twitter to post photos and mission data as Tweets.Altitude (km): 350-425

Iridium Satellite LLC (“Iridium”) hereby requests a two-year renewal of its experimental license to transmit from its space stations to the CU Aerospace Dual Propulsion Experiment (“DUPLEX”) smallsat in the 1618.725–1626.5 MHz band.The DUPLEX is a 6U cubesat mission run by CU Aerospace to test and establish flight heritage for two polymer fiber propulsion systems in low earth orbit. The mission as described in Iridium’s initial application was unavoidably delayed and renewal of authority is necessary to complete the mission. This companion application is to allow the DUPLEX to communicate via the Iridium constellation to allow for TT&C and downlink of critical payload data.As set forth in the CU Aerospace application and subsequent modification, the DUPLEX carries two Near Space Launch (“NSL”) EyeStar S4 transceivers that will be used to transmit to space stations in Iridium’s “Big LEO” constellation in order to relay payload data. The experiment will be launched no earlier than June 15, 2025. Once the DUPLEX is deployed, DUPLEX will be inserted into low earth orbit as described in CU’s application for experimental authority.There will be no change during the experiment in the operating parameters of Iridium’s space stations, which are licensed as Part 25 space stations under Call Sign S2110. For this reason, no operating parameters, other than effective radiated power and emission designator, were identified in Iridium’s original request for an experimental license. The only change for which Iridium seeks experimental authority is adding the DUPLEX as a point of communication. Iridium’s Part 25 space station license does not cover space-to-space communications.
The reason for this STA request is that although the mission will last only a few days after deployment from the ISS, which will occur no earlier than TBD, we need the STA relatively soon. This satellite is going to the ISS on a Cargo Resupply Mission, NG-22. NASA Johnson Space Center (JSC) spectrum office requires the spacecraft FCC license to initiate the processing of a Request for Frequency Authorization (RFA), which they require to start by 2/13/2025.The overall goal of the Alpha mission is to serve as a technical demonstration of a light sail in orbit, verifying the mechanical properties of the polycarbonate material. Also, the sail architecture will demonstrate key functions of next-generation ChipSats. Alpha comprises a 1U CubeSat capable of deploying a free-flying 1m x 1m light sail in response to ground commands. The sail has a sensor-equipped ChipSat attached to each of the 4 corners. These will transmit GPS data to the Cornell University ground station, enabling tracking of the sail to about 10 m accuracy.Operation Start Date: 06/20/2025Operation End Date: 07/20/2025
NASA says the next Cygnus cargo mission to ISS *may* be delayed bc the shipping container w/the Cygnus module was damaged during transport to KSC. Sppsd to launch in June. NASA will add more consumables and food to the April SpX cargo flight just in case.
At a March 7 briefing about the upcoming Crew-10 mission to the station, NASA officials said it was too soon yet to know if the issue would delay the launch of the mission, designated NG-22 and currently scheduled for June. “I expect that we’ll have to have some follow-on discussions and assessments to determine if there is spacecraft damage or any impacts to the overall mission schedule,” said Dana Weigel, NASA ISS program manager, at the briefing.The NG-22 mission was originally scheduled to launch in February, she said, but was delayed by an avionics issue with the spacecraft that neither NASA nor Northrop Grumman had widely publicized.
The following table summarizes the compliance status of Alpha, which will be flown on the NG-22 mission to the International Space Station.
The overall goal of the CU-Alpha mission is to demonstrate the successful deployment of this ChipSat-sail architecture in LEO, verifying the properties of a highly retroreflective sail material for laser propulsion. [...]The satellite will be launched as a secondary payload aboard on an ISS resupply NET May 1, 2025. It will be inserted into an orbit at 422-km apogee and a 410-km perigee at a 51.6° inclination. At two hours following ISS deployment, an initial downlink is made to establish contact with the ground and the detumble/spin-stabilization algorithm is initiated. [...]The spacecraft is a single unit with the dimensions of 1 10 cm X 10 cm X 10 cm CubeSat module (giving an overall dimension of 10 cm X 10 cm X 10 cm.) The total mass is about 1.3 Kg. The sail is 575mm x 575mm in area and weighs 0.10 kg.
NASA announces it won't fly the planned NG-22 mission and will instead fly NG-23 as the next Cygnus mission this fall at the earliest.Full statement:
