Japan Aerospace Exploration Agency Moon Mission Preparing for Final Landing Approach

JAXA Smart Lander for Investigating Moon (SLIM) currently in elliptical 600 x 150 km lunar orbit following Perigee Descent Maneuver #1 (PDM1) which transferred craft from a 600 x 600 km circular orbit on 17 Jan 22:28 JST (13:28 UTC); Operators now preparing for PDM2, which is slated to bring orbit perilune even closer to the lunar surface (15 m) while maintaining 600 km apolune at ~22:40 JST (13:40 UTC) on 19 Jan; Mission success to be measured by 3 criteria: achieving soft landing (minimum), verification of <100 m landing accuracy (full) and continued operations until lunar nightfall (extra); Onboard Multiband Camera to investigate area around 13.2° S, 25.3° E landing site for mineral composition (specifically olivine) and LEV-1 /-2 rovers to explore & image lander; JAXA to livestream landing descent starting 20 Jan 00:00 JST (19 Jan 15:00 UTC)

Peregrine Set for Controlled Reentry into Earth Atmosphere as Astrobotic Works to Collect Data from Payloads

Now ~350,837 km from Earth, Peregrine Moon lander on 8th day of operation in cislunar space is in stable condition with propellant leak ‘practically stopped‘ as Astrobotic and USA government agencies work to determine trajectory for Earth reentry expected NET 18 Jan, although Astrobotic reserves right to determine final flight path independently; 10 payloads continue to receive power despite inability to conduct long duration corrective maneuvers; Joint press conference with NASA discussing mission set for 18 Jan 12:00 EST, which may shed light on Dynetics-built propulsion system valve anomaly

As USA Moon Return Imminent, Historical Impact of First Apollo Images Considered

With NASA working toward Artemis 3 human Moon landing hopefully NLT 4 July 2026, images of the first woman and person of color on the Moon, as well as Astronomy from the Moon images set to be taken via robotic commercial missions, may have societal influence comparable to iconic Apollo 8 Earthrise, which University of Central Lancashire historian Robert Poole argues was even more impactful than the Apollo 11 Moon landing; In article on ‘Image of the Century’, Poole recounts tension within NASA over viewing targets (lunar landscape vs Earth) and desire of crew to commemorate event with Frank Borman signing off ‘Merry Christmas, and God bless all of you – all of you on the good Earth’
