10 Peregrine scientific devices out of 20 receive power, 9 transmit telemetry, 10 in passive mode

10 Peregrine scientific devices out of 20 receive power, 9 transmit telemetry, 10 in passive mode

Peregrine beamed a hello in the telemetry code.

On January 12, 2024, the Astrorobotic spacecraft development company reported, That on Peregrine, 10 scientific devices out of 20 receive power, 9 (with regular communication systems) transmit telemetry, 10 are in a passive state. The machine is still losing fuel due to the failure of the propulsion system (but not as much as before). He is located at a distance of 362 thousand km. from the Earth, which is 94% of the distance to the Moon. According to the updated data, the spacecraft left fuel for approximately 48 hours (previous calculations showed 36 hours).

The fuel leak rate has slowed down by a larger parameter than expected. This was probably due to a drop in pressure in the system. There may still be some design changes going on due to damage to the propulsion tanks or some other factors that make it difficult to estimate the residual fuel calculations.

Astrobotic specialists reported that they had established communication with all scientific instruments of the Peregrine lander. “Ten instruments that need energy are charged, another ten units of cargo remain passive (they were intended to work on the moon). These tools were able to prove their efficiency in space,” the development company reported.

“The two payloads NSS (Neutron Spectrometer System) and LETS (Linear Energy Transfer Spectrometer) conduct a series of measurements of ambient radiation in the interplanetary space around the Earth and the Moon. These two instruments have the ability to analyze different components of emission spectra to provide additional information about cosmic ray activity and current solar activity. Data from the instruments help study interplanetary radiation to understand its effects on humans and electronics,” NASA said.

On January 10, 2024, Astrorobotic reported that Peregrine’s post-accident trajectory had been refined. After the fuel is produced, the device will fly around the Earth in an elongated trajectory.

Mission Status: Peregrine remains stable and with a fully charged battery. The spacecraft continues to transmit valuable data from telemetry and science instruments. It is at a distance of 362,000 km from Earth, and the spacecraft has about 48 hours of fuel left.

Astrorobotic previously reported that a previous version of Peregrine suffered a ruptured oxidizer tank due to problems with a stuck valve between the helium tank and the oxidizer.

On January 9, Astrorobotic admitted that a fuel leak on the Peregrine lunar module leaves no chance of a soft landing on the lunar surface.

On January 8, 2024, United Launch Alliance launched a Vulcan Centaur rocket carrying Astrobotic’s Peregrine lunar lander. The spacecraft is supposed to deliver NASA instruments, hardware wallets with DOGE and BTC, test rovers, memorial capsules, drawings, photographs and objects of cultural importance to the surface of Earth’s natural satellite.

NASA has contracted with Astrobotic to install five science instruments on Peregrine, which are designed to study the lunar surface environment before the arrival of astronauts as part of the Artemis mission. Peregrine’s landing on the lava plain on the visible side of the Moon was scheduled for February 23. It was assumed that this module could become the first private device in history to make a soft landing on the Moon.

A few hours after launch, Peregrine experienced a propulsion anomaly that prevented the vehicle from performing a maneuver to achieve a stable orientation to the Sun. The project team designed and executed an improvised maneuver to reorient the solar panels on the Sun. This maneuver was crowned with success, the landing module began to charge the batteries. Unfortunately, the failure of the propulsion system led to critical fuel losses. Judging by the photo from the on-board camera, the device detected damage to the multilayer insulation, which is an extraordinary situation.
