After a close to 6 month journey along a low energy transfer trajectory, the Japanese ispace Hakuto-R Mission 2 RESILIENCE lander will attempt to land on the moon on Thu, June 5 at 19:17 UTC (3:17 p.m. EDT).
Hakuto-R M2 was launched on Jan 15, alongside the Firefly Aerospace's Blue Ghost lunar lander. The mission will deploy a European-built mini rover named TENACIOUS and other science payloads on the lunar surface.

  Hakuto-R Mission 2
  
  Hakuto-R Mission 2, also called Resilience, is a robotic lunar landing mission launched on 15 January 2025 at 06:11:39 UTC (1:11:39 am EST, local time at the launch site). Developed by the Japanese company ispace, the lander will deliver a new micro rover manufactured by the company's European subsidiary, as well as other payloads. Like Hakuto-R Mission 1, this mission serves as a technology demonstration, with the final goal of providing reliable transportation and data services on the Moon. The lander is named RESILIENCE. Communications were lost approximately half-an-hour after the projected landing. Background The project began development after the Hakuto-R Mission 1 in 2023. The mission plans to use the same overall design with upgrades from the flight data collected in mission 1. Lander specifications The RESILIENCE lander stands 2.3 metres (7 ft 7 in) high, 2.3 metres (7 ft 7 in) wide and has a weight of 340 kilograms (750 lb). The lander includes a micro rover planned to perform an in situ resource utilization...

  It sounds strange that ispace had a contract to collect dirt samples from the lunar surface and "deliver" to NASA for $5,000. Of course, the samples would remain on the moon.
  Other lunar landing missions have similar contracts. Colorado-based Lunar Outpost has a contract for just $1.
  According to NASA, these token contracts are intended to "establish precedents for ownership and use of space resources in compliance with the Outer Space Treaty."

    NASA selects four companies for lunar sample purchases
    
    from Jeff Foust
    
    NASA has made awards to four companies worth exactly $25,001 to obtain lunar samples, part of an effort to establish a space resources precedent.

  Here is the updated table of lunar landing missions in the 21st century.
  Of 16 missions so far, only 6 have succeeded in landing and staying upright on the moon and completing their missions, 4 of them are from the Chinese Space Agency.

    List of missions to the Moon
    
    Missions to the Moon have been numerous and include some of the earliest space missions, conducting exploration of the Moon since 1959. The first partially successful lunar mission was Luna 1 (January 1959), the first probe to leave Earth and fly past another astronomical body. Soon after that the first Moon landing and the first landing on any extraterrestrial body was performed by Luna 2, which intentionally impacted the Moon on 14 September 1959. The far side of the Moon, which is always facing away from Earth due to tidal locking, was seen for the first time by Luna 3 in (7 October 1959). In 1966, Luna 9 became the first spacecraft to achieve a controlled soft landing, while Luna 10 became the first mission to enter orbit, and in 1968 Zond 5 became the first mission to carry terrestrial lifeforms (tortoises) to close proximity of the Moon through a circumlunar approach. The first crewed missions to the Moon were pursued by the Soviet Union and the United States, becoming the climax of the Space Race. While the Soviet Union shifted to robotic sample return missions, the American Apollo program...

  1. Tweet from Spaceflight Now @SpaceflightNow .@ispace_inc ends its livestream without an update on the lander, but it's likely that Resilience had a crash landing. Assuming the final numbers were accurate, the telemetry showed 187 km/h at L-00:01:45 at an altitude of 52 m. The lander should've been between 3-1 km above the Moon's surface at that point.

  Update from ispace about the failed HAKUTO-R M2 mission -
  After decelerating from 20 km altitude to near vertical attitude, telemetry was lost.
  The laser rangefinder used to measure the distance to the lunar surface experienced delays in obtaining valid measurement values. As a result, the lander was unable to decelerate sufficiently, crashing on the lunar surface at ~187 km/h.
  The table in post #6 gets another red row 🙁.

  The ispace HAKUTO-R mission 1 crash-landed for a different reason on April 25, 2023.
  Around 5 km altitude, the onboard software incorrectly presumed that the radar altimeter was faulty because its reading of 5 km diverged from that of the inertial measurement unit. The spacecraft descended slowly thinking it was near the surface, ran out of fuel and then crashed into the lunar surface at more than 100 meters per second.

    Software problem blamed for ispace lunar lander crash
    
    from Jeff Foust
    
    A software glitch kept a lunar lander from properly determining its altitude, leading to a crash on its landing attempt last month, Japan's ispace said.

  After landing, the ispace RESILIENCE lander will have about 14 earth days (one lunar day) to complete its mission, before night falls, bringing darkness and brutally cold temperatures.
  Similar to other recent robotic landers, RESILIENCE is powered by solar cells and will not have sufficient energy storage to survive the lunar night.

  Space is hard, lunar landings are even harder.
  Only 4 of 13 robotic lander missions since 2019 have been successful, as shown in the table below.
  Note that the ispace Hakuto-R Mission 1 lander ended with a hard landing in April 2023.
  Sending best wishes to RESILIENCE for a successful landing.

  The ispace RESILIENCE lander is currently in a 100 km altitude circular orbit around the moon, traveling at ~5,800 km/h, getting ready for the next set of maneuvers to start the landing sequence.
  Here is a recent pic on the lunar surface taken by the spacecraft.

  Here is a closer look at the ispace HAKUTO-R Mission 2 landing site in Mare Frigoris. The landing site, at 60.5°N 4.6°E, seems to be located in a shallow depression at the northern end of a fairly flat area.
  The camera angle is from the North looking South.
