NASA has awarded Space Exploration Technologies Corp. of Hawthorne, California, one task order to launch two CubeSat Launch Initiative missions as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract.
The CubeSats are targeted to launch no earlier than 2025 on a SpaceX Falcon 9 rocket. NASA will specify payloads closer to launch.
Building on NASA’s previous procurement efforts to foster development of a growing U.S. commercial launch market, VADR provides Federal Aviation Administration-licensed commercial launch services for payloads that can tolerate higher risk. By using a lower level of mission assurance, and commercial best practices for launching rockets, these highly flexible contracts help broaden access to space through lower launch costs.
SpaceX is one of 13 companies NASA selected for VADR contracts in 2022. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contracts.
It’s launch day for NASA’s TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) mission! A pair of small satellites wait atop a Rocket Lab Electron rocket for liftoff from Launch Complex 1 in Māhia, New Zealand. This launch, named Rocket Like A Hurricane, is the first of two planned launches, each sending a pair of shoebox-sized satellites, called CubeSats, to low-Earth orbit, where they will more frequently collect data to help increase understanding of these deadly storms and improve tropical cyclone forecasts complementing other NASA and partner satellites, including the Global Precipitation Measurement (GPM) Mission and the Suomi National Polar-orbiting Partnership (Suomi NPP).
A two-hour launch window opens at 9 p.m. EDT Sunday, May 7, (1 p.m. Monday, May 8, New Zealand Standard Time).
Together the two launches will attempt to place four CubeSats in two equally spaced orbital planes, so they are spread over the globe for optimal coverage. The CubeSats will study the formation and development of tropical cyclones, known as hurricanes in the Atlantic and typhoons in the West Pacific. The full TROPICS constellation will make observations more often than what is possible with current weather satellites. When they reach orbit, these TROPICS satellites will join the TROPICS Pathfinder satellite which is already in orbit.
All four TROPICS satellites need to be deployed into their operational orbit within a 60-day period. The TROPICS satellites will cover the part of the Earth where tropical cyclones form and will work in concert to improve observations of the powerful storms. The distribution of the satellites means that one should pass over any spot in an area stretching from the Mid-Atlantic region of the United States to the southern coast of Australia about once an hour. TROPICS will provide data on temperature, precipitation, water vapor, and clouds by measuring microwave frequencies, providing insight into storm formation and intensification. This new data, coupled with information collected from other weather satellites, will increase understanding of tropical cyclones, and should improve forecasting models.

NASA is announcing two small CubeSats missions to launch on a commercial dedicated rideshare flight as part of the agency’s Educational Launch of Nanosatellites (ELaNa) initiative, which helps advance scientific and human exploration, as well as reduce the cost of new space missions, and expand access to space.
The CubeSat missions, which will study parts of Earth’s atmosphere and its radiation belt dynamics, are targeted for launch no earlier than April 2023 on a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.
The Colorado Inner Radiation Belt Experiment (CIRBE) and Low-Latitude Ionosphere/Thermosphere Enhancements in Density (LLITED) are ELaNa missions 47 and 40, respectively.
CIRBE is a 3U CubeSat (1U, or unit = 10cm x 10cm x 10cm) from the University of Colorado Boulder, designed to provide state-of-the-art measurements within Earth’s radiation belt in a highly inclined low-Earth orbit. CIRBE aims for a better understanding of radiation belt dynamics, consequently improving the forecast capability of the energetic particles known to pose a threat to orbiting satellites as well as astronauts during spacewalks.

“Despite being the first scientific discovery of the space age, there are still many unsolved puzzles regarding the dynamics of these energetic particles,” said Dr. Xinlin Li, CIRBE principal investigator and professor at the university’s Laboratory for Atmospheric and Space Physics.
CIRBE’s sole instrument, Relativistic Electron Proton Telescope integrated little experiment-2 (REPTile-2), is an advanced version of an instrument previously in space from 2012 to 2014. The original REPTile could detect three energy channels, whereas REPTile-2 can distinguish 50 distinct channels, providing far greater measurement of elusive high energy particles with potential to damage satellites and penetrate spacesuits. REPTile-2 will measure the energies of incident electrons and protons, with its data downlinked to the ground via S-band radio. At mission’s end, the spacecraft’s orbit will begin degrading, eventually re-entering the atmosphere and burning up.
NASA’s LLITED consists of two 1.5U CubeSats developed by The Aerospace Corporation, Embry-Riddle Aeronautical University in Florida, and the University of New Hampshire (UNH). LLITED will study two late-day features of Earth’s atmosphere between 217 to 310 miles, with the aim of gaining a greater understanding of the interactions between the neutral and electrically charged parts of the atmosphere, consequently improving upper-atmosphere modeling capabilities and predictions for orbital proximity and re-entry.
“For the first time, we will be able to make simultaneous and co-located measurements of two phenomena in lower thermosphere/ionosphere – Equatorial Ionization Anomaly (EIA) and Equatorial Temperature Wind Anomaly (ETWA) – from a CubeSat platform,” said Dr. Rebecca Bishop, principal investigator for LLITED. “The two LLITED CubeSats will be able to observe changes in time and space of the two features.”
Both LLITED CubeSats carry three science instruments – a GPS radio-occultation sensor provided by Aerospace, an ionization gauge from UNH, and a planar ion probe provided by Embry-Riddle. Working together, the instruments will show how these atmospheric regions of enhanced density form, evolve, and then interact with each other after sunset.
“Because CubeSats can weigh 100 times less than larger satellites, missions such as LLITED demonstrate the potential of these small and cost-effective spacecraft to perform cutting-edge, comprehensive science experiments that previously were not feasible within traditional program resources,” said Bishop.
NASA’s CubeSat Launch Initiative (CSLI) supporting the agency’s Launch Services Program at Kennedy Space Center in Florida provides launch opportunities for small satellite payloads built by U.S. universities, high schools, NASA Centers, and non-profit organizations. To date, NASA has selected more than 225 CubeSat missions, representing participants from 42 states, the District of Columbia, Puerto Rico, and over 115 unique organizations.
NASA has awarded Phantom Space Corp. four task orders to launch four CubeSat Launch Initiative missions as part of the agency’s Venture-class Acquisition of Dedicated and Rideshare (VADR) launch services contract. The CubeSats will launch no earlier than 2024 on Phantom’s Daytona rocket.
Building on NASA’s previous procurement efforts to foster development of new launch vehicles for NASA payloads, VADR provides Federal Aviation Administration-licensed commercial launch services for payloads that can tolerate higher risk. By using a lower level of mission assurance, and commercial best practices for launching rockets, these highly flexible contracts help broaden access to space through lower launch costs.
