NASA’s CubeSat Launch Initiative is sending a group of four small satellites, called CubeSats, to the International Space Station as ELaNa 51 (Educational Launch of Nanosatellites). These small payloads have been developed by NASA and universities and will be deployed from low Earth orbit. 

Once circling Earth, the satellites will help demonstrate and mature technologies meant to improve solar power generation, detect gamma ray bursts, determine crop water usage, and measure root-zone soil and snowpack moisture levels. 

The suite of satellites will hitch a ride aboard a SpaceX Falcon 9 rocket and Dragon spacecraft set to deliver additional science, crew supplies, and hardware for the company’s 30th commercial resupply services mission for NASA. Liftoff is targeted for 4:55 p.m. EDT Thursday, March 21, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. 

First Cornhusker State CubeSat 

The first CubeSat from Nebraska is the Big Red Sat-1, which aims to investigate and improve the power production ability of solar cells. It is built by a team of middle and high school students mentored by University of Nebraska-Lincoln undergraduate engineering students. 

The satellite measuring 1U, or one unit, (about four inches cubed), will test out Perovskite cells, a new type of solar cell designed to enhance power production with and without direct exposure to sunlight. The team will compare the power production to that of typical cells, called gallium arsenide solar cells, also flying on the CubeSat. 

Detecting Gamma Ray Bursts 

BurstCube is a NASA-developed 6U CubeSat designed to search the sky for brief flashes of high-energy light such as gamma-ray bursts, solar flares, and other hard X-ray transients. 

Long and short gamma ray bursts are stellar remnants that can be the result of some of the universe’s most powerful explosions like the collapse or collision of massive stars, or when a neutron star collides with a black hole. BurstCube will use a new kind of compact, low-power silicon photomultiplier array to detect the elusive bursts of light. 

With the ability to detect these brief flashes from space, BurstCube can help alert other observatories to witness changes in the universe as they happen. Astronomers can also benefit from the information because these bursts are important sources for gravitational wave discoveries. 

Rooting Out Earth Water Sources from Space 

The SigNals of Opportunity P-band Investigation, or SNoOPI, is a technology demonstration CubeSat designed to improve the detection of moisture levels on a global scale of underground root-zone and within snowpacks. 

Root zone soil moisture and snow water equivalent play critical roles in the hydrologic cycle, impacting agricultural food production, water management, and weather phenomena. When scientists understand the amount of water in the soil, crop growth can be accurately forecasted, and irrigation can become more efficient. 

The 6U CubeSat is collaboratively developed by NASA, Purdue University in Indiana, Mississippi State University, and the United States Department of Agriculture.  

The fourth in the suite of small satellites, the University of Hawaiʻi at Mānoa’s HyTI (Hyperspectral Thermal Imager) is also a 6U CubeSat designed to study water sources. 

Developed in partnership with NASA to map irrigated and rainfed cropland, HyTI is a pathfinder demonstration that packs the Hyperspectral Imager Instrument, temporal resolution thermal infrared imager focal plane technology, and high-performance onboard computing to help better understand crop water use and water productivity of major world crops. 

With these tools, HyTI can help develop a more detailed understanding of the movement, distribution, and availability of water and its variability over time and space, an important contribution to global food and water security issues.  

These payloads were selected through NASA’s CSLI, which provides U.S. educational institutions, nonprofits with an education/outreach component, informal educational institutions (museums and science centers), and NASA centers with access to space at a low cost. 

Once the CubeSat selections are made, NASA’s Launch Services Program works to pair them with a launch that is best suited to carry them as auxiliary payloads.

Processing of the large solar arrays built for NASA’s Europa Clipper is now underway inside the Payload Hazardous Servicing Facility at the agency’s Kennedy Space Center in Florida. 

Planned to arrive at Jupiter in April 2030, the spacecraft will study Jupiter’s moon Europa, which shows strong evidence beneath its icy crust of a global ocean over twice the volume of all Earth’s oceans. Europa is currently considered one of the most promising habitable environments in our solar system.

Once processing of the first five-panel solar array is complete, technicians will remove it from the gravity offload fixture, which helps support the weight of the array. The same steps will then be repeated with the second solar array. Built by Airbus in Leiden, Netherlands, the arrays arrived at Kennedy late last month by truck, after travelling to the U.S. by air. 

When both solar arrays are installed and deployed on Europa Clipper – the agency’s largest spacecraft ever developed for a planetary mission – the spacecraft will span a total length of more than 100 feet and weigh 7,145 pounds without the inclusion of propellants. The spacecraft needs the large solar arrays to collect enough light to power it as it operates in the Jupiter system, which is more than five times as far from the Sun as Earth. 

Europa Clipper is being assembled at NASA’s Jet Propulsion Laboratory in Southern California and is managed in partnership with Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The spacecraft will ship to Florida later this year for launch aboard a SpaceX Falcon Heavy rocket from Kennedy’s Launch Complex 39A. NASA’s Launch Services Program, based at Kennedy, is managing the launch service.

NASA and SpaceX are now targeting no earlier than May 2024 for the launch of the fourth and final satellite in NOAA’s Geostationary Operational Environmental Satellites (GOES) – R Series, GOES-U. The new date allows for additional testing and preparation of a new Falcon Heavy center core booster after a liquid oxygen leak was discovered during routine new booster testing.     

NOAA oversees the GOES-R Series Program through an integrated NOAA-NASA office, managing the ground system, operating the satellites, and distributing their data to users worldwide. NASA’s Goddard Space Flight Center manages the acquisition of the spacecraft and instruments and also built the Magnetometer instrument for GOES-T and GOES-U. NASA’s Launch Services Program, based at Kennedy Space Center manages the launch services for the GOES missions. Lockheed Martin designs, builds, and tests the GOES-R series satellites. L3Harris Technologies provides the primary instrument, the Advanced Baseline Imager, along with the ground system, which includes the antenna system for data reception. 

Signal Acquired: NASA’s PACE Spacecraft Begins Its Science Mission

NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft has successfully made contact with ground stations back on Earth providing teams with early readings of its overall status, health, operation, and capabilities postlaunch.  

A full postlaunch assessment review to determine PACE’s readiness to move into the operational phase of its mission will be conducted in the coming weeks.  

Information collected throughout PACE’s mission will benefit society in the areas of ocean health, harmful algal bloom monitoring, ecological forecasting, and air quality. PACE also will contribute new global measurements of ocean color, cloud properties, and aerosols, which will be essential to understanding the global carbon cycle and ocean ecosystem responses to a changing climate.  

The PACE’s mission is designed to last at least three years, though the spacecraft is loaded with enough propellant to expand that timeline more than three times as long.

A series of rapid events occurs after launch. After Max Q – the moment of peak mechanical stress on the rocket – the nine Merlin engines of the Falcon 9’s first stage will finish their burn and cut off during a phase called MECO or Main Engine Cutoff. 

Quickly after MECO, the stage separation sequence occurs. The second stage carrying NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft will continue on its journey to sun-synchronous orbit.  

Coming up next, the Falcon 9’s second stage engine ignites, and the protective payload fairings will be jettisoned to reveal NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft to the vacuum of space for the first time.   

Meanwhile, the first stage of the rocket begins its recovery journey for a vertical landing at SpaceX Landing Zone 1 at Cape Canaveral Space Force Station in Florida. Landing should occur about eight and a half minutes after liftoff.

When NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission launches at 1:33 a.m. EST from Space Launch Complex 40 at Cape Canaveral Space Force Station, the SpaceX Falcon 9 rocket will follow a little used flight path, or trajectory. 

After liftoff, the rocket will head south along the Florida coastline during its powered flight to insert the spacecraft into a sun-synchronous orbit. That means the spacecraft will always be in the same “fixed” position relative to the Sun as it orbits over the Earth’s polar regions. 

Provided the nighttime skies over South Florida are clear, millions of residents will be able to look up and see the Falcon 9 overhead within minutes after launch.
