When the European Space Agency’s Jupiter Icy Moons Explorer (Juice) flew past our Moon in August 2024, its Radar for Icy Moon Exploration (RIME) instrument listened to radio wave echoes to reveal the height of the lunar surface.

Curiosity Blog, Sols 4600-4601: Up and Over the Sand Covered Ramp
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on July 13, 2025 — Sol 4598, or Martian day 4,598 of the Mars Science Laboratory mission — at 15:24:10 UTC. NASA/JPL-Caltech Written by Sharon Wilson Purdy, Planetary Geologist at the Smithsonian National Air and Space Museum
Earth planning date: Monday, July 14, 2025
The Curiosity rover continues to navigate through the region of Mount Sharp characterized by the boxwork terrain. After successfully completing a drive of about 34 meters over the weekend (about 112 feet), the rover parked near the edge of a smooth, sandy stretch at the base of a ridge that leads to the most prominent and complex network of boxwork structures seen so far.
Due to the lack of exposed bedrock in the immediate workspace, the science team opted to give some of the rover’s contact science instruments a break. With the dust removal tool (DRT) and APXS instruments stowed, the extra energy allowed the Mars Hand Lens Imager (MAHLI) to take high resolution images of “Playa de la Gallina” to survey the uniform, smooth surface consisting of sand and pebble-sized material.
The ChemCam and Mastcam teams scheduled several observations in this two-sol plan that further investigated the rocks and structures in our immediate vicinity and surroundings. ChemCam LIBS was used to target “El Olivo” to determine the chemistry of the bumpy textured bedrock near the rover, which was also imaged by a Mastcam stereo mosaic. Additional Mastcam stereo mosaics include fractures at “El Corral” and linear troughs at “Chapare.” Further away, ChemCam’s Remote Micro Imager (RMI) will provide insight into an intriguing section of scoured features within the Mishe Mokwa butte.
The environmental working group continues to keep an eye in the sky and planned a supra-horizon movie and a dust-devil survey as part of their ongoing monitoring campaign of the atmospheric conditions in Gale Crater.
The 21-meter-long drive (about 69 feet) at the end of this plan will maneuver the rover past the sandy ramp to the top of the main boxwork region. From here, the science team will be able to explore this fascinating area of particularly large boxwork structures. Stay tuned as Curiosity continues to climb higher and delve deeper into the geologic history of Mars!

NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/Alex Parker This image, taken by NASA’s New Horizons spacecraft on July 14, 2015, is the most accurate natural color image of Pluto. This natural-color image results from refined calibration of data gathered by New Horizons’ color Multispectral Visible Imaging Camera (MVIC). The processing creates images that would approximate the colors that the human eye would perceive, bringing them closer to “true color” than the images released near the encounter. This single color MVIC scan includes no data from other New Horizons imagers or instruments added. The striking features on Pluto are clearly visible, including the bright expanse of Pluto’s icy, nitrogen-and-methane rich “heart,” Sputnik Planitia.

The TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission will help scientists understand an explosive process called magnetic reconnection and its effects in Earth’s atmosphere. Credit: University of Iowa/Andy Kale NASA will hold a media teleconference at 11 a.m. EDT on Thursday, July 17, to share information about the agency’s upcoming Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, or TRACERS, mission, which is targeted to launch no earlier than late July.
The TRACERS mission is a pair of twin satellites that will study how Earth’s magnetic shield — the magnetosphere — protects our planet from the supersonic stream of material from the Sun called solar wind. As they fly pole to pole in a Sun-synchronous orbit, the two TRACERS spacecraft will measure how magnetic explosions send these solar wind particles zooming down into Earth’s atmosphere — and how these explosions shape the space weather that impacts our satellites, technology, and astronauts.
Also launching on this flight will be three additional NASA-funded payloads. The Athena EPIC (Economical Payload Integration Cost) SmallSat, led by NASA’s Langley Research Center in Hampton, Virginia, is designed to demonstrate an innovative, configurable way to put remote-sensing instruments into orbit faster and more affordably. The Polylingual Experimental Terminal technology demonstration, managed by the agency’s SCaN (Space Communications and Navigation) program, will showcase new technology that empowers missions to roam between communications networks in space, like cell phones roam between providers on Earth. Finally, the Relativistic Electron Atmospheric Loss (REAL) CubeSat, led by Dartmouth College in Hanover, New Hampshire, will use space as a laboratory to understand how high-energy particles within the bands of radiation that surround Earth are naturally scattered into the atmosphere, aiding the development of methods for removing these damaging particles to better protect satellites and the critical ground systems they support.
Audio of the teleconference will stream live on the agency’s website at:
nasa.gov/live
Participants include:
Joe Westlake, division director, Heliophysics, NASA Headquarters Kory Priestley, principal investigator, Athena EPIC, NASA Langley Greg Heckler, deputy program manager for capability development, SCaN, NASA Headquarters David Miles, principal investigator for TRACERS, University of Iowa Robyn Millan, REAL principal investigator, Dartmouth College To participate in the media teleconference, media must RSVP no later than 10 a.m. on July 17 to Sarah Frazier at: sarah.frazier@nasa.gov. NASA’s media accreditation policy is available online.
The TRACERS mission will launch on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California.
This mission is led by David Miles at the University of Iowa with support from the Southwest Research Institute in San Antonio. NASA’s Heliophysics Explorers Program Office at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, manages the mission for the agency’s HeliophysicsDivision at NASA Headquarters in Washington. The University of Iowa, Southwest Research Institute, University of California, Los Angeles, and University of California, Berkeley, all lead instruments on TRACERS that will study changes in the Earth’s magnetic field and electric field. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the Venture-class Acquisition of Dedicated and Rideshare contract.
