A sampling of recent articles, press releases, etc. related to student and amateur CubeSat / SmallSat projects and programs (find previous smallsat roundups here):
Intuitive Machines, the company developing the Nova-C, offered Engineering students at Embry-Riddle this once-in-a-lifetime opportunity — to design and build a camera system that will deploy from the Nova-C to capture the landing and, in the process, become the first university student project ever to land on the moon.
…
Supported by a network of national scientists, Embry-Riddle’s “EagleCam” team — three Engineering professors along with a large interdisciplinary team of students — is designing a camera and communication system, or CubeSat, to launch to the moon and shoot the astronomical selfie. Just before approach, the CubeSat will deploy and freefall 100 feet to the surface to give the world its first glimpse of the spacecraft’s lunar landing.
The creation of Space Force has inspired a renewed interest in space systems research and innovation. In August, the Naval Postgraduate School (NPS) received funding from the DOD to lead a project to streamline space technology among Five Eye (FVEY) countries. The project, headed by NPS professors Giovanni Minelli and Wenschel Lan, involves sending up two CubeSats containing experimental technology created by NPS students and New Zealand researchers. The payloads must be ready to launch into orbit by 2022. Once in space, the payloads will communicate with NPS researchers in the new Radio Frequency (RF) Testing Lab that overlooks the Monterey Bay.
…
NPS’ Space Labs have also brought elements of space to its students, so they can properly test out their payloads. The CubeSat skeleton is 3D printed, so students don’t have to start completely from scratch. They can carefully create their prototypes, using Raspberry Pi single-board computers in the clean room before testing them out in a variety of situations. For example, students have access to a thermo-pressure chamber and shaking machine that can “shake your teeth out,” according to Lan. They also conduct weather balloon tests to see how payloads respond to orbit-like atmospheric conditions. The goal is to think of everything that could possibly go wrong before actually sending a payload up into space.

The 2U NUTSAT was designed by the National Formosa University with the backing of the National Space Organization (NSPO) in Taiwan. One of the three NSPO cubesats launching this year, NUTSAT is a systems engineering training education program integrating an ADS-B receiver onto the cubeSat to demonstrate and enhance commercial aviation safety technology. NUTSAT is the first of the three cubesats to go for the launch integration.

The Milky Way galaxy is in the recycling business. Our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars, according to a NASA-funded study in the journal Nature Astronomy.
A halo is a large region filled with hot gas that surrounds a galaxy, also known as a “circumgalactic medium.” The heated gaseous halo around the Milky Way was the incubator for the Milky Way’s formation some 13 billion years ago and could help solve a longstanding puzzle about where the missing matter of the universe might reside.
The new findings come from observations made by a small spacecraft called HaloSat. It is in a class of minisatellites called CubeSats and is roughly the size of a toaster, measuring 4-by-8-by-12 inches (about 10-by-20-by-30 centimeters) and weighing about 26 pounds (12 kilograms). Built by the University of Iowa, HaloSat was launched from the International Space Station in May 2018 and is the first CubeSat funded by NASA’s Astrophysics Division.
While tiny compared to NASA’s Chandra X-ray Observatory, HaloSat’s X-ray detectors view a much wider piece of the sky at once and therefore are optimized to doing the sort of wide-area survey needed to measure the galactic halo.
Because of their small size, CubeSats allow NASA to conduct low-cost scientific investigations in space. Six CubeSats to date have been selected in this Astrophysics Division series.
In the new study, researchers conclude the circumgalactic medium has a disk-like geometry, based on the intensity of X-ray emissions coming from it.
The Iowa Univ. team and its partners, NASA/GSFC ( Goddard Space Flight Center) and JHU/APL (Johns Hopkins University/Applied Physics Laboratory), focused on developing the scientific instruments while Blue Canyon Technologies built the CubeSat hardware: HaloSat – eoPortal Directory – Satellite Missions
Deployment of HaloSat and NASA JPL’s RainCube from the ISS on July 13th, 2018:
Scientists at CU Boulder are developing a satellite about the size of a toaster oven to explore one of the cosmos’ most fundamental mysteries: How did radiation from stars punch its way out of the first galaxies to fundamentally alter the make-up of the universe as it we know it today.
Those insights will come from the Supernova Remnants and Proxies for ReIonization Testbed Experiment (SPRITE), a NASA-funded mission led by the Laboratory for Atmospheric and Space Physics (LASP) at CU Boulder.
Scheduled to launch in 2022, the $4 million SPRITE is the latest in LASP’s line of little-spacecraft-that-could. This “CubeSat” will measure just over a foot in length and will weigh about 40 pounds. It will also collect unprecedented data from modern-day stars and supernovas to help scientists better understand a time in the history of the cosmos called the “Epoch of Reionization”—a period in which the universe’s first stars lived fast and hard, burning out and going supernova in a span of just a few million years.
“We’re trying to establish what the universe was like when it first formed and how it evolved to where it is today,” said Brian Fleming, a research professor at LASP who is leading the SPRITE mission.
The team also hopes that SPRITE will show just how much CubeSats can achieve. To date, most of these miniature spacecraft have focused on studying phenomena that are closer to home—such as weather on Earth or flares erupting from the surface of the sun.
“There has been a perception that to do new astrophysics you need to collect a lot of light so you need something big,” said Fleming, also of the Department of Astrophysical and Planetary Sciences. “SPRITE is trying to do something different. There’s a lot of science you can do by optimizing your design and using new technologies.”

** Neutron-1 CubeSat studies neutrons in low earth orbit as preparation for the LunaH-Map satellite to use neutrons to study distribution of the lunar surface. The neutron detectors on the satellites are developed by a Arizona State University team.
Water ice, or lunar water, is the first evidence that water could exist on the moon and was confirmed to be on the moon by NASA in 2018.
Principal investigator on the project and professor Craig Hardgrove, along with an ASU team, developed a neutron detector that will be integrated with the Neutron-1 3U CubeSat mission led by Lloyd French, a program manager for University of Hawaii at Manoa and co-founder of the Hawaii Space Flight Laboratory.
The neutron detector allows researchers to map neutron abundances in low earth orbit as part of the LunaH-Map mission. The detector will also assist in UHM’s mission to study neutrons while testing its own efficacy for its intended mission.
The LunaH-Map satellite will orbit the moon in search of water ice sources on its surface. The CubeSat mission helps pave the way forLunaH-Map’s next year.
Neutron-1 will be deployed from the ISS late this year. LunaH-Map is currently set to launch in November 2021 and will take about six months to reach the Moon.

** Ohio State student built Bobcat-1 CubeSat reached the ISS via the recent Antares/Cygnus cargo mission. When deployed from the station, the CubeSat will study
Measuring approximately 12”x4”x4”, the nanosatellite will be deployed into low-Earth orbit to study Global Navigation Satellite Systems (GNSS), like GPS, in an effort to improve the availability and performance of these navigation systems for other satellites and spacecraft.
The satellite is one of 11 small spacecraft designed at American universities selected by NASA’s CubeSat Launch initiative in 2018 to be transported into space. Dr. Sabrina Ugazio, assistant professor of electrical engineering and computer science in the Russ College of Engineering and Technology, and four OHIO engineering students developed the nanosatellite and the ground station, located on the Stocker Center roof, that will control and communicate with the spacecraft during its nine-month orbit.
For 3 yrs @russcollege prof Sabrina Ugazio & 4 students designed the 12″x 4″x4″ nanosatellite, Bobcat-1.
Oct. 2 it arrived safely at the International Space Station.
Over the next 9 month it will orbit 250 miles above Earth.
