Cape Canaveral, Florida – Astrobotic’s Peregrine Mission One has successfully launched to the Moon. Peregrine is now flying solo on its way to the Moon, where it will attempt a lunar landing on February 23, 2024. Peregrine could become the first commercial lander, and first American lander in over 50 years, to land on the Moon.
At 2:18am ET on January 8, 2024, the company’s Peregrine Lunar Lander lifted off on a United Launch Alliance (ULA) Vulcan rocket from Cape Canaveral Space Force Station in Florida. Peregrine launched on Vulcan’s maiden flight, known as Cert-1. Vulcan lifted Peregrine to an altitude of approximately 500 km above the Earth, where, at approximately 50 minutes after launch, the lander separated from the rocket and successfully powered on. Following separation, Astrobotic successfully contacted the lander and began receiving telemetry.
“Today Peregrine Mission One achieved a number of big milestones,” said John Thornton, CEO of Astrobotic. “Peregrine powered on, acquired a signal with Earth, and is now moving through space on its way to the Moon. These successes bring us one step closer to seven nations landing on the Moon, six of which have never been to the Moon before.”
Peregrine Mission One is the first successful launch under NASA’s Commercial Lunar Payload Services initiative. The mission is delivering scientific instruments and payloads to the Moon’s Gruithuisen Domes region. The NASA instruments aboard Peregrine will help NASA prepare for the Artemis program’s missions to enable a sustained human presence on the Moon.
Peregrine is carrying a total of 20 payloads from seven nations and 16 commercial customers. The payloads come from space agencies, universities, companies, and individuals across the globe. This includes the first lunar surface payloads from the Mexican and German space agencies, and the first lunar payloads from the countries of the United Kingdom, Hungary, and Seychelles. One of the payloads, DHL MoonBox, contains mementos and messages from over 100,000 individuals around the world.
The Peregrine lander itself, which was assembled at Astrobotic’s headquarters in Pittsburgh, PA, includes parts manufactured by hundreds of suppliers from across the US, including 184 companies in Pennsylvania alone.
“Astrobotic would like to thank its suppliers, customers, sponsors, supporters, and 250-employee team, who have worked tirelessly for years to make this moment possible,” said Thornton.
Following Peregrine Mission One, Astrobotic plans to continue its lunar exploration efforts with the launch of Griffin Mission One in late 2024. Griffin, the largest lunar lander since the Apollo lunar module, will carry NASA’s Volatiles Investigating Polar Exploration Rover (VIPER) to the south pole of the Moon. On arrival, VIPER will search for the presence of water ice in the permanently shadowed regions of Mons Mouton.
An update on Peregrine Mission One:
After successfully separating from United Launce Alliance’s Vulcan rocket, Astrobotic’s Peregrine lunar lander began receiving telemetry via the NASA Deep Space Network. Astrobotic-built avionics systems, including the primary command and data handling unit, as well as the thermal, propulsion, and power controllers, all powered on and performed as expected. After successful propulsion systems activation, Peregrine entered a safe operational state. Unfortunately, an anomaly then occurred, which prevented Astrobotic from achieving a stable sun-pointing orientation. The team is responding in real time as the situation unfolds and will be providing updates as more data is obtained and analyzed.
Update #2 on Peregrine Mission One:
We continue to gather data and report our best assessment of what we see. The team believes that the likely cause of the unstable sun-pointing is a propulsion anomaly that, if proven true, threatens the ability of the spacecraft to soft land on the Moon. As the team fights to troubleshoot the issue, the spacecraft battery is reaching operationally low levels. Just before entering a known period of communication outage, the team developed and executed an improvised maneuver to reorient the solar panels toward the Sun. Shortly after this maneuver, the spacecraft entered an expected period of communication loss. We will provide more updates as Peregrine comes in view of the ground station again.
Update #3 on Peregrine Misson One
We have successfully re-established communications with Peregrine after the known communication blackout. The team’s improvised maneuver was successful in reorienting Peregrine’s solar array towards the Sun. We are now charging the battery. The Mission Anomaly Board continues to evaluate the data we’re receiving and is assessing the status of what we believe to be the root of the anomaly: a failure within the propulsion system.
We are grateful for the outpouring of support we’re receiving – from messages on social media to phone calls and helping hands. This is what makes the space industry so special, that we unite in the face of adversity. A heartfelt thank you from the entire Peregrine Mission One team.
Update #4 on Peregrine Misson One
Unfortunately, it appears the failure within the propulsion system is causing a critical loss of propellant. The team is working to try and stabilize this loss, but given the situation, we have prioritized maximizing the science and data we can capture. We are currently assessing what alternative mission profiles may be feasible at this time.
