UPDATE #18 FOR PEREGRINE MISSION ONE

Peregrine has been operational in space for 7 days and 13 hours. The spacecraft continues to be responsive, operational, and stable, and remains on its previously reported trajectory toward Earth’s atmosphere. The propellant leak caused by the anomaly has practically stopped. The team continues to work with NASA and U.S. Government agencies to assess the final trajectory path in which the vehicle is expected to burn up. Peregrine is now about 218,000 miles away from Earth. 

This photo was taken in space today, with a camera on one of Peregrine’s payload decks. This is the same camera view as the first photo we received from the spacecraft on January 8, 2024.


UPDATE #19 FOR PEREGRINE MISSION ONE The Peregrine spacecraft continues to be responsive and stable and has been operational in space for 8 days and 16 hours. The mission team is continuously monitoring the spacecraft’s trajectory back to Earth. We remain in contact with our U.S. Government partners to ensure as safe a re-entry path as possible. As a reminder, Peregrine reached apogee on Saturday and is now about 183,000 miles from Earth.


UPDATE #20 FOR PEREGRINE MISSION ONE Astrobotic has positioned the Peregrine spacecraft for a safe, controlled re-entry to Earth over a remote area of the South Pacific. The team has been continuously monitoring our re-entry analysis with NASA, which indicates a re-entry path over the indicated area below, with no anticipated hazards. A safe re-entry is our top priority, so the team developed a two-step maneuver to move the spacecraft and change its projected trajectory. 

The first step required a main engine burn. Due to the propulsion anomaly, it was impossible to operate the main engines normally. As such, we developed a plan to fire the main engines with a series of very short burns. We conducted a test burn of all five main engines. Each pulse was spaced out to avoid overheating, allowing our mission control team to monitor results and the spacecraft’s status after every burn. Following this, we performed a series of 23 small main engine burns.

Secondly, we adjusted the spacecraft’s attitude so the force induced by the leaking propellant shifted us towards the South Pacific Ocean. The result of these two maneuvers is the ellipse in the graphic shown.

The procedures the team executed were to minimize the risk of debris reaching land. Astrobotic continues to work closely with NASA and other relevant government authorities to keep everyone informed and to solicit feedback as appropriate.

Peregrine has been operating in space for 9 days and 16 hours. It is 139,000 miles (223,700 km) from Earth. We expect re-entry to occur at approximately 4pm Thursday, January 18 (US Eastern time).

As re-entry is now targeted for Thursday, we are moving our previously scheduled media telecon to Friday, January 19 at 1pm (US Eastern time) to provide a comprehensive mission update.


Update #21 for Peregrine Mission One Peregrine has been operating in space for 10 days and 8 hours and is approximately 30,000 miles above Earth, continuing its controlled re-entry. The trajectory remains on track with our planned path toward a safe area over open water in the South Pacific. The vehicle is stable, operational, and responsive. We remain in contact with appropriate government authorities to keep them informed of the vehicle’s position and planned trajectory, which remains unchanged.

The stunning image here of Earth from Peregrine was taken by the mission team this morning. The first attempt to take this photo yielded an oversaturated image, with the Sun making the image too bright to see the Earth. As a result, the team precisely slewed the spacecraft to reposition the Sun to be hidden behind the thin payload deck strut just to the left of Earth, which produced the starburst effects on the vehicle and revealed the Earth’s crescent. This image is completely unaltered.

We dedicate this image to our customers, partners, and team who all stood with us throughout Peregrine Mission One.
