Why does the Moon have two different faces?. That question frames the lunar dichotomy: The nearside that faces us is different than the lunar farside. Scientists have worked hard to understand why that is, and new research says that the presence of certain minerals could explain why.

The Japanese company ispace released the technical details that likely doomed the landing of their Hakuto-R Mission 2 lunar lander earlier this month. According to a press release, their engineers narrowed down the issue to a failure of the spacecraft's Laser Range Finder (LRF). Engineers suspect that the LRF's performance deteriorated during flight, causing it to be slow to make its measurements and update its descent speed correctly. It hit the Moon at 42 meters a second, crashing hard.

There’s nothing to get a scientist’s heart pumping like a good, old-fashioned statistical debate. When it comes to topics like finding Earth analogues or hints of a biosignature in an atmosphere, those statistical debates could have real world consequences, both for the assignment of additional observational resources, but also for humanity’s general understanding of itself in the Universe. A new paper from two prominent exoplanet hunters, David Kipping from Columbia and Björn Benneke from UCLA, argues that their colleagues in the field of exoplanet detection have been doing statistics all wrong for decades, and make a argument for how better to present their results to the public.

One of Webb’s strong points is its ability to directly image planets around another solar system. The telescope has been in operation for long enough now that a flood of those images are starting, as more and more systems come under the telescope’s gaze. One of those is described in a recent paper and press release from NASA. According to the paper, the planet in a nearby system is about the size of Saturn, which would make it the smallest planet ever found by direct observation.

Curiosity Blog, Sols 4586-4587: Straight Drive, Strategic Science NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on June 28, 2025 — Sol 4583, or Martian day 4,583 of the Mars Science Laboratory mission — at 03:20:22 UTC. NASA/JPL-Caltech

Written by Scott VanBommel, Planetary Scientist at Washington University in St. Louis

Earth planning date: Monday, June 30, 2025

Our weekend drive placed Curiosity exactly where we had hoped: on lighter-toned, resistant bedrock we have been eyeing for close study. Curiosity’s workspace tosol did not contain any targets suitable for DRT. After a detailed discussion by the team, weighing science not only in tosol’s plan but the holiday-shifted sols ahead, the decision was made to perform contact science at the current workspace and then drive in the second sol of the plan.

Normally, drives in the second sol of a two-sol plan are uncommon, as we require information on the ground to assess in advance of the next sol’s planning. At present however, the current “Mars time” is quite favorable, enabling Curiosity’s team to operate within “nominal sols” and receive the necessary data in time for Wednesday’s one-sol plan. DAN kicked off the first sol of the plan with a passive measurement, complemented by another in the afternoon and two more on the second sol. Arm activities focused on placing MAHLI and APXS on “La Paz” and “Playa Agua de Luna,” two lighter-toned, laminated rocks.

The rest of the first sol was rounded out with ChemCam LIBS analyses on “La Joya” followed by further LIBS analyses on “La Vega” on the second sol, once Curiosity’s arm was out of the way of the laser. ChemCam and Mastcam additionally imaged “Mishe Mokwa” prior to the nearly straight drive of about 20 meters (about 66 feet). Environmental monitoring activities, imaging of the CheMin inlet cover, and a SAM EBT activity rounded out Curiosity’s efforts on the second sol.

An Update From the 2025 Mars 2020 Science Team Meeting

A behind-the-scenes look at the annual Mars 2020 Science Team Meeting

Written by Katie Stack Morgan, Mars 2020 Acting Project Scientist 

The Mars 2020 Science Team gathered for a week in June to discuss recent science results, synthesize earlier mission observations, and discuss future plans for continued exploration of Jezero’s crater rim. It was also an opportunity to celebrate what makes this mission so special: one of the most capable and sophisticated science missions ever sent to Mars, an experienced and expert Science Team, and the rover’s many science accomplishments this past year.  

We kicked off the meeting, which was hosted by our colleagues on the RIMFAX team at the University of Oslo, with a focus on our most recent discoveries on the Jezero crater rim. A highlight was the team’s in-depth discussion of spherules observed at Witch Hazel Hill, features which likely provide us the best chance of determining the origin of the crater rim rock sequence.   

On the second day, we heard status updates from each of the science instrument teams. We then transitioned to a session devoted to “traverse-scale” syntheses. After 4.5 years of Perseverance on Mars and more than 37 kilometers of driving (more than 23 miles), we’re now able to analyze and integrate science datasets across the entire surface mission, looking for trends through space and time within the Jezero rock record. Our team also held a poster session, which was a great opportunity for in-person and informal scientific discussion.  

The team’s modern atmospheric and environmental investigations were front and center on Day 3. We then rewound the clock, hearing new and updated analyses of data acquired during Perseverance’s earlier campaigns in Jezero’s Margin unit, crater floor, and western fan. The last day of the meeting was focused entirely on future plans for the Perseverance rover, including a discussion of our exploration and sampling strategy during the Crater Rim Campaign. We also looked further afield, considering where the rover might explore over the next few years.  

Following the meeting, the Science Team took a one-day field trip to visit Gardnos crater, a heavily eroded impact crater with excellent examples of impact melt breccia and post-impact sediment fill. The team’s visit to Gardnos offered a unique opportunity to see and study impact-generated rock units like those expected on the Jezero crater rim and to discuss the challenges we have recognizing similar units with the rover on Mars. Recapping our Perseverance team meetings has been one of my favorite yearly traditions (see summaries from our 2022, 2023, and 2024 meetings) and I look forward to reporting back a year from now. As the Perseverance team tackles challenges in the year to come, we can seek inspiration from one of Norway’s greatest polar explorers, Fridtjof Nansen, who said while delivering his Nobel lecture, “The difficult is that which can be done at once; the impossible is that which takes a little longer.”
