NASA’s ELaNa 43 Prepares for Firefly Aerospace Launch


A Satellite for Optimal Control and Imaging (SOC-i) CubeSat awaits integration at Firefly’s Payload Processing Facility at Vandenberg Space Force Base, California on Thursday, June 6, 2024. SOC-i, along with several other CubeSats, will launch to space on an Alpha rocket during NASA’s Educational Launch of Nanosatellites (ELaNa) 43 mission as part of the agency’s CubeSat Launch Initiative and Firefly’s Venture-Class Launch Services Demonstration 2 contract.

NASA is readying for the launch of several small satellites to space, built with the help of students, educators, and researchers from across the country, as part of the agency’s CubeSat Launch Initiative.

The ELaNa 43 (Educational Launch of Nanosatellites 43) mission includes eight CubeSats flying on Firefly Aerospace’s Alpha rocket for its “Noise of Summer” launch from Space Launch Complex-2 at Vandenberg Space Force Base, California. The 30-minute launch window will open at 9 p.m. PDT Wednesday, June 26 (12 a.m. EDT Thursday, June 27).

NASA’s CubeSat Launch Initiative (CSLI) is an ongoing partnership between the agency, educational institutions, and nonprofits, providing a path to space for educational small satellitemissions. For the ELaNa 43 mission, each satellite is stored in a CubeSat dispenser on the Firefly rocket and deployed once it reaches sun-synchronous or nearly polar orbit around Earth.

CubeSats are built using standardized units, with one unit, or 1U, measuring about 10 centimeters in length, width, and height. This standardization in size and form allows universities and other researchers to develop cost-effective science investigations and technology demonstrations.

CatSat – University of Arizona, Tucson

CatSat, a 6U CubeSat with a deployable antenna inside a Mylar balloon, will test high-speed communications. Once the CatSat reaches orbit, it will inflate to transmit high-definition Earth photos to ground stations at 50 megabits per second, more than five times faster than typical home internet speeds.

The CatSat design inspiration came to Chris Walker after covering a pot of pudding with plastic wrap. The CatSat principal investigator and professor of Astronomy at University of Arizona noticed the image of an overhanging light bulb created by reflections off the concave plastic wrap on the pot.

“This observation eventually led to the Large Balloon Reflector, an inflatable technology that creates large collecting apertures that weigh a fraction of today’s deployable antennas,” said Walker. The Large Balloon Reflector was an early-stage study developed through NASA’s Innovative Advanced Concepts program.

KUbeSat-1 – University of Kansas, Lawrence

The KUbeSat-1, a 3U CubeSat, will use a new method to measure the energy and type of primary cosmic rays hitting the Earth, which is traditionally done on Earth. The second payload, the High-Altitude Calibration will measure very high frequency signals generated by cosmic interactions with the atmosphere. KUbeSat-1 is Kansas’ first small satellite to launch under NASA’s CSLI.

MESAT-1 – University of Maine, Orono

MESAT-1, a 3U CubeSat, will study local temperatures across city and rural areas to determine phytoplankton concentration in bodies of water to help predict algal blooms.  MESAT-1 is Maine’s first small satellite to launch under NASA’s CSLI.

R5-S4, R5-S2-2.0 ­­­­­- NASA’s Johnson Space Center

R5-S4 and R5-S2-2.0, both 6U CubeSats, will be the first R5 spacecraft launched to orbit to test a new, lean spacecraft build. The team will monitor how each part of the spacecraft performs, including the computer, software, radio, propulsion system, sensors, and cameras in low Earth orbit.

NASA and Firefly Aerospace engineers review the integration plan for the agency’s CubeSat R5 Spacecraft 4 (R5-S4) at Firefly Aerospace’s Payload Processing Facility at Vandenberg Space Force Base, California on Wednesday, April 24, 2024.

“In the near term, R5 hopes to demonstrate new processes that allows for faster and cheaper development of high-performance CubeSats,” said Sam Pedrotty, R5 project manager at NASA’s Johnson Space Center in Houston. “The cost and schedule improvements will allow R5 to provide higher-risk ride options to low-Technology Readiness Levels payloads so more can be demonstrated on-orbit.”

Serenity Teachers in Space

Serenity, a 3U CubeSat equipped with data sensors and a camera, will communicate with students on Earth through amateur radio signals and send back images. Teachers in Space launches satellites as educational experiments to stimulate interest in space science, technology, engineering, and math among students in North America.

SOC-i University of Washington, Seattle

Satellite for Optimal Control and Imaging (SOC-i), a 2U CubeSat, is a technology demonstration mission of attitude control technology used to maintain its orientation in relation to the Earth, Sun, or other body. This mission will test an algorithm to support autonomous operations with constrained attitude guidance maneuvers computed in real-time aboard the spacecraft. SOC-i will autonomously rotate its camera to capture images.

TechEdSat-11 (TES-11) – NASA’s Ames Research Center, California’s Silicon Valley

TES-11, a 6U CubeSat, is a collaborative effort between NASA researchers and students to evaluate technologies for use in small satellites. It’s part of ongoing experiments to evaluate new technologies in communications, a radiation sensor suite, and experimental solar panels, as well as to find ways to reduce the time to de-orbit.

NASA awarded Firefly Aerospace a fixed-price contract to fly small satellites to space under a Venture-Class Launch Services Demonstration 2 contract in 2020. NASA certified Firefly Aerospace’s Alpha rocket as a Category 1 in May, which authorized its use during missions with high risk tolerance.

NASA’s Launch Services Program is responsible for launching rockets delivering spacecraft that observe Earth, visit other planets, and explore the universe.

Firefly Alpha Rocket Launch Attempt Scrubbed; Team Aims to Try Again Tuesday

Ground equipment issues spoil the countdown Monday night at Vandenberg Space Force Base

After two dramatic countdown aborts, the Alpha rocket team ran out of time for a third liftoff attempt Monday night at Vandenberg Space Force Base.

The Texas-based Firefly Aerospace rocket remains standing at Space Launch Complex-2, awaiting the chance to conduct the mission dubbed “Noise of Summer.”

The team might try as soon as Tuesday night for the Alpha rocket’s fifth launch, Firefly officials said.

Seconds away from lifting off shortly after 9 p.m. Monday, the countdown halted abruptly. However, with a 30-minute window, the team recycled the countdown amid hopes of still getting the rocket off the ground. 


Despite their efforts, they had to stop the night’s second countdown and began the post-scrub chores so they could try another day.

“This is how it goes. You know the saying, you’d rather be on the ground wishing you were flying than flying wishing you were on the ground,” a commentator said on the livestream webcast.

Equipment on the ground reportedly caused the problems that forced the team to call off Monday’s countdown with a liftoff.

“Our launch today was scrubbed due to a ground support issue. The team has identified the solution and is working quickly to meet our next launch window,” Firefly representatives said.

The next attempt could come as soon 9:03 p.m. Tuesday, with the window remaining open for 30 minutes.


Alpha will carry eight CubeSats under a NASA contract to prove the capabilities of a new rocket and provide more access to space for small satellites and spacecraft.

Leading up to Monday night’s countdown, the team conducted a rapid launch operation, successfully transporting the payload fairing, or rocket’s nose cone, to the launch pad and mating it to the rocket 14 hours before the planned Monday night liftoff. 

Historically, those chores have been completed months or weeks in advance for some missions involving different rockets. 

If the rocket departs at the opening of the launch window, it could create a twilight effect. However, the marine layer seems intent on interfering with the view for spectators in coastal areas.

Even cameras at the launch site struggled to display Alpha on Monday, prompting a launch commentator to wryly ask, “Is the rocket getting less visible?”

A livestream of the countdown and launch is scheduled to begin 30 minutes before the liftoff and can be found by clicking here.

Firefly Aerospace won’t try for liftoff of its Alpha rocket on Tuesday night at Vandenberg Space Force Base, and the next try remains up in the air. 

“Firefly has decided to stand down on today’s Alpha #FLTA005 launch to give the team more time to evaluate data and test systems from the first attempt,” the company announced Tuesday afternoon. 

The company will work closely with Western Range officials and its NASA customer to determine the next launch window, Firefly officials said.

The team experienced two last-minute aborts Monday night due to equipment on the ground. 


The Tuesday afternoon delay announcement came hours after Firefly officials said they remained on track for their next attempt. 

“Alpha & all 8 @NASA payloads remain healthy after last night’s scrub due to a faulty ground support equipment connection that has been fixed,” Firefly officials said mid-day Tuesday. 

The mission, called “Noise of Summer,” will place eight CubeSats with various purposes into orbit under a contract with NASA. 

This will be Alpha’s fifth launch since its debut liftoff in 2021.
