Communications Achieved for NASA’s Four Starling CubeSats

Mission managers have established command communications with all four of NASA’s Starling CubeSats! The spacecraft are progressing through payload and propulsion tests, the final stage of a pre-operations checklist called commissioning.

The Starling spacecraft – which project team members nicknamed Blinky, Pinky, Inky, and Clyde – are part of an ambitious test to develop self-coordinating robotic swarms for space research and exploration.

Progress so far has been as expected for three of the four spacecraft – Pinky, Inky, and Clyde. An initial communication issue with Blinky was addressed by updating estimates of its orbital position and instructing the satellite to better align its antennas with ground station receivers. Operators have achieved operational two-way communications with all Starling units and are still investigating the root cause of the issue.

In addition, data analysis of Blinky’s onboard attitude control system, which manages the spacecraft’s orientation, showed that it was having to work to counteract a disturbance. Initial troubleshooting suggested this was likely connected to a propulsion system leak, which was subsequently remediated. Operators are working to better understand the issue and how it might impact the mission.

After this final stage of commissioning, the Starling spacecraft will begin a procedure called a “drift arrest maneuver,” adjusting the orbital positions of each craft to bring them into proper alignment to begin testing swarm activities.

NASA’s Starling Commissioning Begins, Team Works to Bolster Comms

Each of NASA’s four Starling spacecraft stabilized themselves, deployed solar panels, and made initial contact shortly after their July 17 launch. Starling operators report nominal health for all the CubeSats.

The spacecraft are undergoing a series of preparation and testing activities, called commissioning, ahead of their mission to demonstrate autonomous communications, positioning, maneuvering, and decision-making capabilities. Starling’s commissioning phase includes three stages: spacecraft bus commissioning, payload commissioning, and propulsion system commissioning.

Three of Starling’s four CubeSats have completed spacecraft bus commissioning ahead of schedule. As of July 21, the mission team continues working to establish robust two-way communications with the fourth spacecraft so that it can join its fellow CubeSats in the next stage of commissioning.

Starling CubeSats Have Deployed

NASA’s four Starling CubeSats are confirmed to have deployed from the Rocket Lab’s Electron kick stage. The spacecraft, which are designed to work together as a “swarm,” have reached low Earth orbit to begin their mission to test technologies for autonomous positioning, networking, maneuvering, and decision-making.

Now, the Starling swarm will power up and attempt initial contact with the ground; a process that may occur overnight or in the next several days.

It’s Launch Day for NASA’s Starling Mission!

Welcome to launch day for NASA’s Starling CubeSat mission! A team of four satellites wait atop a Rocket Lab Electron rocket for liftoff from Launch Complex 1 in Māhia, New Zealand. This launch, named Baby Come Back, will send Starling’s cereal box-sized satellites, called CubeSats, to low Earth orbit, where they will test new autonomous spacecraft swarm technologies.

A two-hour launch window opens at 7:30 p.m. EDT (11:30 a.m. Tuesday, July 18, New Zealand Standard Time). Rocket Lab is providing a live launch broadcast, available on the company’s website approximately 20 minutes before launch.

Today’s launch aims to deploy the four Starling CubeSats more than 300 miles above Earth. Following commissioning, the spacecraft will demonstrate maneuver planning, communications networking, relative navigation, and autonomous coordinated science measurements, all with minimal intervention from operators on the ground.

This ambitious test is an important step in advancing self-coordinating robotic swarms for future science and exploration missions to the Moon, Mars, and deep space.  Projects like the upcoming HelioSwarm mission, which will launch nine spacecraft to study the Sun like never before, will benefit from lessons learned from Starling.

NASA Awards SpaceX Launch Services Task Order for CubeSat Mission

NASA logo

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.

Seeking Signal Acquisition

The final two TROPICS CubeSats successfully deployed from a Rocket Lab Electron rocket after launch. The rocket named Coming To A Storm Near You lifted off at at 11:46 p.m. EDT Thursday, May 25, (3:46 p.m. NZST Friday, May 26th).

The team is now working to seek signal acquisition from this pair of TROPICS CubeSats. NASA will continue to assess data from periodic pass opportunities over ground stations located across the globe. It is not unexpected for CubeSats to take some time to establish communications. We will provide confirmation when signal is acquired.

While the launches are complete, the scientific work on orbit for the constellation is just beginning. So, continue to follow along for blog updates and stay connected with the mission on social media. This concludes our coverage of this launch.

TROPICS CubeSats Have Deployed

NASA’s TROPICS CubeSats have deployed from the Rocket Lab’s Electron kick stage. The two CubeSats will reach low Earth orbit to begin their mission.

Each of the CubeSats was designed to last approximately two years, but analysis, lifetime testing of key parts, and on-orbit experiences with similar hardware could help the satellites surpass their design lifetime.

Electron’s Second Stage Separates

The second stage of Rocket Lab’s Electron has cut off and separated from the payload fairing’s kick stage. In around 20 minutes, the kick stage engine will ignite and burn for almost four minutes before it cuts off.

Electron Performs Battery Hot Swap

The Electron rocket has successfully completed the battery hot swap, switching power between batteries. The next milestone is second stage separation in about two minutes.
