The CubeSat was deployed on January 31, 2019 and has been sending back data since its departure.
According to a recent study, only 45% of CubeSat units last longer than 60 days in service.
The Undergraduate Nano Ionospheric Temperature Explorer CubeSat, or UNITE CubeSat, was funded by a NASA Undergraduate Student Instruments Project (USIP) grant.
This interesting spacecraft will be dubbed OSCaR and it’s intended to collect space debris, or space junk.
Standing for “Obsolete Spacecraft Capture and Removal”, it’s a three-unit CubeSat being created by a team of researchers at Rensselaer Polytechnic Institute, the USA’s oldest technological research university.
Some are the size of a toaster. Others a suitcase. They can ride into space as secondary payloads in a rocket’s “trunk,” or even be tossed out of an airlock, to start their missions. Small satellites, often collectively called “cubesats,” are changing the way we explore space and monitor our home planet.

Here is the latest episode of NASA’s Space to Ground report on activities related to the International Space Station:
** NASA Johnson also posts the longer SpaceCast Weekly – May 10, 2019:
SpaceCast Weekly is a NASA Television broadcast from the Johnson Space Center in Houston featuring stories about NASA’s work in human spaceflight, including the International Space Station and its crews and scientific research activities, and the development of Orion and the Space Launch System, the next generation American spacecraft being built to take humans farther into space than they’ve ever gone before.
** Here is the latest episode of This Week @NASA reports on “Supplies, Research and Equipment Delivered to the Space Station”
For example, the UCLA team of 11 students designed and built an experimental magnetic pump named Blue Dawn that will work in zero-gravity:
“The goal was to see if we could design an efficient fluid pump without any moving parts to work in zero-gravity, which has never been done before,” said Alexander Gonzalez, fourth-year physics major and undergrad science lead on the project. Such a low-maintenance pump would be ideal for moving various liquids on the International Space Station, and could reduce the risk of motorized pump failures for rovers and even future bases on the moon or Mars.
** Living tissues embedded in 3D electronics chips were among the research projects on the recent SpaceX Dragon Cargo mission to the ISS. The company Emulate, Inc. sent “organs-on-chips” to the ISS to study the Effects of Microgravity on Human Physiology including
the effect of microgravity and other space-related stressors on the brain blood barrier. It uses fully automated tissue chip technology, a Brain-Chip, consisting of living neuronal and vascular endothelial cells in a micro-engineered environment. Results may provide insight into the relationship between inflammation and brain function and a better understanding of neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
As the Sun ramps down to minimum it will have months where there is no activity, as happened in February 2019, and months, such as in March and April, where more sunspots appear.
Eventually the quiet months will become dominate, and soon thereafter, when activity increases again (assuming it does), the solar science community will then announce the date of true minimum.
We are not there. Normally it can take a year or more for the Sun to settle down. If activity declines as indicated by the red curve, it could take as long four years, which would be a record-long minimum. The difference will tell us whether the eleven-year solar cycle is continuing, or the Sun is heading into a grand minimum, with no significant sunspots for decades.
** Measuring the magnetism of Mars and Jupiter were discussed on the recent TMRO.tv episode Orbit 12.15:
NASA’s MAVEN Magnetometer Instrument Lead Dr. Jared Espley joins us to talk about MAVEN, Juno and how we measure the magnetism of planets in our local system. More information on MAVEN can be found here: https://www.nasa.gov/mission_pages/ma… And more information on Juno can be found here: https://www.nasa.gov/mission_pages/ju…
Mars has been the most extensively studied planet in the Solar System, except of course Earth. For the last 25 years, these missions have focused on the search for life by “following the water.” Although we have acquired compelling evidence of flowing liquid water on early Mars, the fundamental question about how water could be stable under Martian atmospheric conditions remains unsolved. Everything we have learned about Mars points towards a freezing cold Martian climate that would be incapable of stabilizing liquid water throughout Mars’ history.
Grains of dust from the asteroid Itokawa actually contain a surprising amount of water, two cosmochemists from Arizona State University in Tempe report May 1 in Science Advances.
“We didn’t really expect water to be there in Itokawa at all,” says study coauthor Maitrayee Bose. But if similar asteroids have similar amounts of water, the space rocks could have been a major source of water for the early Earth.
The many pits surrounding Arsia Mons highlight a far greater mystery about Martian geology. Some geologists believe that the many meandering channels we see on Mars could have formed not from surface flow as generally assumed but by underground drainage that washed out voids below the ground which in turn caused the surface to subside, forming those meandering channels.
Yet, as far as I can tell, the only place where scientists have been able to identify a significant number of potential cave openings are on the volcanic slopes of Arisa Mons and its neighboring giant volcanos. There are exceptions, such as this spectacular pit at the head of a channel in the transition zone between the southern highlands and the northern lowlands, as well as two different pits, here and here, that are located in the lowlands in Utopia Basin. Overall however the bulk of pits imaged by MRO appear to be on the slopes of the giant volcanoes, with the majority so far found near Arsia Mons.
A camera on the spacecraft’s robotic arm snapped the photos on April 24 and 25, the 145th Martian day, or sol, of the mission. In local Mars time, the shots were taken starting around 5:30 a.m. and then again starting around 6:30 p.m. As a bonus, a camera under the lander’s deck also caught clouds drifting across the Martian sky at sunset.
“NASA’s InSight lander used the Instrument Deployment Camera (IDC) on the end of its robotic arm to image this sunset on Mars on April 25, 2019, the 145th Martian day, or sol, of the mission. This was taken around 6:30 p.m. Mars local time.” Credits: NASA/JPL-Caltech. Full image and caption
For the first time, NASA’s Mars Odyssey orbiter has caught the Martian moon Phobos during a full moon phase. Each color in this new image represents a temperature range detected by Odyssey’s infrared camera, which has been studying the Martian moon since September of 2017. Looking like a rainbow-colored jawbreaker, these latest observations could help scientists understand what materials make up Phobos, the larger of Mars’ two moons.
Odyssey is NASA’s longest-lived Mars mission. Its heat-vision camera, the Thermal Emission Imaging System (THEMIS), can detect changes in surface temperature as Phobos circles Mars every seven hours. Different textures and minerals determine how much heat THEMIS detects.
Such measurements can help determine the composition of the moon, particularly the minerals and metals:
Iron and nickel are two such metals. Depending on how abundant the metals are, and how they’re mixed with other minerals, these data could help determine whether Phobos is a captured asteroid or a pile of Mars fragments, blasted into space by a giant impact long ago.
These recent observations won’t definitively explain Phobos’ origin, Bandfield added. But Odyssey is collecting vital data on a moon scientists still know little about – one that future missions might want to visit. Human exploration of Phobos has been discussed in the space community as a distant, future possibility, and a Japanese sample-return mission to the moon is scheduled for launch in the 2020s.
Astronomers developed a mosaic of the distant Universe that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image, called the Hubble Legacy Field, contains roughly 265,000 galaxies that stretch back to just 500 million years after the Big Bang.
The wavelength range of this image stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time. The faintest and farthest galaxies in the image are just one ten-billionth the brightness of what the human eye can observe.
“Now that we have gone wider than in previous surveys, we are harvesting many more distant galaxies in the largest such dataset ever produced,” said Garth Illingworth of the University of California, Santa Cruz, leader of the team that assembled the image. “No image will surpass this one until future space telescopes like James Webb are launched.”
This video “takes the viewer on a journey into the Hubble Legacy Field”:
This image, a composite of several observations captured by ESO’s VLT Survey Telescope (VST), shows the ESA spacecraft Gaia as a faint trail of dots across the lower half of the star-filled field of view. These observations were taken as part of an ongoing collaborative effort to measure Gaia’s orbit and improve the accuracy of its unprecedented star map.

These observations were taken as part of an ongoing collaborative effort to measure Gaia’s orbit and improve the accuracy of its unprecedented star map.
Gaia, operated by the European Space Agency (ESA), surveys the sky from orbit to create the largest, most precise, three-dimensional map of our Galaxy. One year ago, the Gaia mission produced its much-awaited second data release, which included high-precision measurements — positions, distance and proper motions — of more than one billion stars in our Milky Way galaxy. This catalogue has enabled transformational studies in many fields of astronomy, addressing the structure, origin and evolution the Milky Way and generating more than 1700 scientific publications since its launch in 2013.
In order to reach the accuracy necessary for Gaia’s sky maps, it is crucial to pinpoint the position of the spacecraft from Earth. Therefore, while Gaia scans the sky, gathering data for its stellar census, astronomers regularly monitor its position using a global network of optical telescopes, including the VST at ESO’s Paranal Observatory[1]. The VST is currently the largest survey telescope observing the sky in visible light, and records Gaia’s position in the sky every second night throughout the year.
** A Galaxy Grouping in 2D and 3D: Stephan’s Quintet;
In 1877, Edouard Stephan discovered a tight visual grouping of five galaxies located in the constellation Pegasus. The galaxies of Stephan’s Quintet are both overlapping and interacting, and have become the most famous among the compact groups of galaxies. Astronomers have long known that four of the galaxies (all of which are yellowish-white in this video) form a physical group in space, while the fifth (bluish) is a foreground galaxy. In addition, a sixth galaxy (yellowish-white and on the far left) is likely to be part of the physical grouping. Hence, this 2D quintet that is a 3D quartet may actually be a 2D sextet that is a 3D quintet.
This visualization makes apparent the spatial distribution of these galaxies. The video starts with a view that matches our 2D perspective. As the sequence travels in 3D, the foreground blue spiral, NGC 7320, quickly passes by the camera. The possible sixth galaxy member on the left, NGC 7320C, is seen at roughly the same distance as the remaining four galaxies. The camera turns to pass between two strongly interacting galaxies, NGC 7319 (left) and NGC 7318B (right), with each galaxy’s spiral structure distorted by the gravitational interaction. In contrast, NGC 7318B overlaps in 2D with the more distant elliptical NGC 7318A, but does not have a strong interaction. The other elliptical, NGC 7317, is also seen as more distant than the strongly interacting pair. In 3D, the four or five galaxies in this group are gathered together by their mutual gravity, and may collide and merge together in the future.

[ Update: A message from Blue Origin today points to a video of the Blue Moon unveiling yesterday.
On May 9, 2019, our founder discussed his vision to go to space to benefit Earth.
Watch the full replay of this event …
In addition, he also announced the Blue Moon lunar lander, which is capable of taking people and payloads to the lunar surface. Below you’ll find more information about these announcements.
Blue Moon lunar lander: Blue Origin announced Blue Moon, its large lunar lander capable of delivering multiple metric tons of payload to the lunar surface based on configuration and mission. The cargo variant revealed today can carry 3.6 metric tons to the surface. We have also designed a variant of the lander that can stretch to be capable of carrying a 6.5-metric-ton, human-rated ascent stage. Blue also announced it can meet the current Administration’s goal of putting Americans on the Moon by 2024 with the Blue Moon lunar lander.
BE-7 engine: The Blue Moon lunar lander will be powered by the BE-7 engine, a new addition to Blue Origin’s family of engines. The BE-7’s 40 kN (10,000 lbf) thrust is designed for large lunar payload transport. The engine’s propellants are a highly-efficient combination of liquid oxygen and liquid hydrogen. The BE-7 will have its first hotfire this summer. The engine will be available for sale to other companies for use in in-space and lander applications.
Club For the Future: A non-profit founded by Blue Origin dedicated to inspiring and engaging the next generation of dreamers and space entrepreneurs as we journey to preserve Earth and unlock the potential of living and working in space.

** Jeff Bezos unveiled Blue Origin‘s Blue Moon lunar lander design at an event today –
Blue Moon is a flexible lander delivering a wide variety of small, medium and large payloads to the lunar surface. Its capability to provide precise and soft landings will enable a sustained human presence on the Moon.
Initially for cargo and later for human transport:
The Blue Moon lander can deliver large infrastructure payloads with high accuracy to pre-position systems for future missions. The larger variant of Blue Moon has been designed to land an ascent vehicle that will allow us to return Americans to the Moon by 2024.

** Highlights of engine development by PLD Space in Spain, which is developing suborbital and orbital rockets with reusable boosters:
This fact sheet lays out the envisioned launch cost and frequency, for instance, and states that SpinLaunch aims to loft its first payload by 2022. And we get the following description of the launch system:
“SpinLaunch utilizes existing technology and components from oil/gas/mining and wind turbine industries to construct an innovative mass-acceleration system, which achieves very high launch speeds without the need for enormous power generation or massive infrastructure. After ascending above the atmosphere, a relatively small, low-cost onboard rocket will be used to provide the final required velocity for orbital insertion. Because the majority of the energy required to reach orbit is sourced from ground-based electricity, as opposed to complex onboard rocket propulsion, total launch cost is reduced by an order of magnitude over existing launch systems.”
** Rocket Crafters partners with RUAG of Switzerland on development of rockets based on Rocket Crafters’s hybrid motor technology:
Rocket Crafters, a manufacturer of advanced rockets operating from the Florida Space Coast, and RUAG Space, a leading independent product supplier for spacecraft, electronics and launchers, signed a Memorandum of Understanding (MOU) at Satellite Conference 2019 in Washington D.C. – creating a new supplier agreement in the small launcher market.
Rocket Crafters will collaborate with RUAG on the design, development and procurement of a sounding rocket guidance and navigation system, nose cone and aeroshell in order to support an initial test flight, with the goal to achieve reliable, cost effective and fast time-to-market.

** Leaders of launch services providers gave their views on the status of the industry this week during panels at the Satellite 2019 conference:
The test appears to have occurred last month at Delamar Dry Lake in Nevada, where SpaceX was conducting one of dozens of drop tests it intends to perform to demonstrate the safety of its Crew Dragon spacecraft. This was a “single-out” test in which one of Dragon’s four parachutes intentionally failed before the test. “The three remaining chutes did not operate properly,” [NASA’s chief of human spaceflight Bill Gerstenmaier] said.
A follow-up:
(Very) unofficially, a source says they may switch to a thicker parachute design to compensate for issues discovered in the test. Although not ideal, this is a fairly normal part of spacecraft development.
The Aerospace team in Albuquerque, New Mexico, is playing a major role in the flight, making sure all the satellites fit together aboard the world’s most powerful rocket. Aerospace engineers ensure the payloads don’t negatively affect each other in this complex arrangement by using a rideshare mission assurance protocol called “Do-No-Harm” (DNH). DNH is a process that focuses on ensuring no payload on a rideshare mission will negatively affect the on-orbit functionality of any other payload. The individual payloads on STP-2 are all responsible for their own mission success, but through the DNH process, Aerospace is ensuring that everyone inside the Falcon Heavy nose cone plays nice with each other.
Gwynne Shotwell, SpaceX’s president and chief operating officer, said the launch will carry “dozens of satellites,” adding more prototypes to the two currently in low Earth orbit.
“This next batch of satellites will really be a demonstration set for us to see the deployment scheme and start putting our network together,” she said at the Satellite 2019 conference here. “We start launching satellites for actual service later this year.”
Shotwell said SpaceX anticipates launching two to six more times for its Starlink broadband constellation in addition to the May 15 launch. How many Starlink launches occur this year depend on the results of this first batch, she said.
*** Falcon 9 booster legs retracted rather than removed. SpaceX introduced the Block 5 Falcon first stage boosters in 2018, hailing the design as the culmination of many lessons learned from landing and reusing the earlier generation boosters. Blk 5 boosters should provide up to a dozen launches between overhauls and to re-fly as soon as 24 hours after a launch. This requires quick operations such as simply retracting the landing legs back into their launch positions. During the past year, though, observers at Port Canaveral saw workers removing the legs before recovered Blk 5 boosters were transported back to the hangars.
Still more video to come of Load and Transport. This is CRS-17, B1056 Booster. This video runs in real time{ No fast motion}. Takes place over three days. We know it’s long, we left out hours of footage.
SpaceX has completed the first landing leg retraction, crews locked it in place and removed the cable.
This is one of the upgraded features on Falcon 9 Block 5, for rapid reusability.
Amid a flurry of new construction at SpaceX’s Boca Chica facilities, technicians have begun to install thruster pods on Starhopper in anticipation of the prototype’s first untethered flights.
According to CEO Elon Musk, Starhopper’s “untethered hover tests” will begin with just one Raptor engine installed, potentially allowing hops to restart within the next few weeks. SpaceX is currently testing Raptor SN03 (and possibly SN02) a few hundred miles north in McGregor, Texas, just a few hours’ drive south once the engine is deemed flight-ready. Meanwhile, Starhopper itself needs a considerable amount of new hardware before it can begin Raptor-powered flight testing.
