ISS Expedition 13 Flight Engineer, Thomas Reiter, on board ISS processes samples for the Renal Stone investigation.NASA Exposure to microgravity induces bone atrophy/bone loss which increases circulating calcium, impacting the renal stone risk. Risk mitigation strategies including exercise and hydration are well-defined although the ability to treat a renal stone during exploration missions is not yet available.

Technicians with ESA (European Space Agency) and Airbus installed the four solar array wings on NASA’s Orion spacecraft for Artemis II on March 3. The solar array wings, attached to the service module, deploy after Orion reaches space to power the spacecraft.
Orion’s service module provides propulsion, thermal control, and electrical power, as well as air and water for the crew during their mission around the Moon.
Each solar array wing has 15,000 solar cells to convert sunlight to electricity and is nearly 23 feet in length when fully deployed. In space, the arrays can turn on two axes to remain aligned with the Sun.
Artemis II is the first crewed mission under NASA’s Artemis campaign. Through Artemis, the agency will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

Credit: NASA NASA has selected Firefly Aerospace Inc. of Cedar Park, Texas, to provide the launch service for the agency’s Investigation of Convective Updrafts (INCUS) mission, which aims to understand why, when, and where tropical convective storms form, and why some storms produce extreme weather. The mission will launch on the company’s Alpha rocket from NASA’s Wallops Flight Facility in Virginia.
The selection is part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to make fixed-price indefinite-delivery/indefinite-quantity awards during VADR’s five-year ordering period, with a maximum total value of $300 million across all contracts.
The INCUS mission, comprised of three SmallSats flying in tight coordination, will investigate the evolution of the vertical transport of air and water by convective storms. These storms form when rapidly rising water vapor and air create towering clouds capable of producing rain, hail, and lightning. The more air and water that rise, the greater the risk of extreme weather. Convective storms are a primary source of precipitation and cause of the most severe weather on Earth.
Each satellite will have a high frequency precipitation radar that observes rapid changes in convective cloud depth and intensities. One of the three satellites also will carry a microwave radiometer to provide the spatial content of the larger scale weather observed by the radars. By flying so closely together, the satellites will use the slight differences in when they make observations to apply a novel time-differencing approach to estimate the vertical transport of convective mass.
NASA selected the INCUS mission through the agency’s Earth Venture Mission-3 solicitation and Earth System Science Pathfinder program. The principal investigator for INCUS is Susan van den Heever at Colorado State University in Fort Collins. Several NASA centers support the mission, including Langley Research Center in Hampton, Virginia, the Jet Propulsion Laboratory in Southern California, Goddard Space Flight Center in Greenbelt, Maryland, and Marshall Space Flight Center in Huntsville, Alabama. Key satellite system components will be provided by Blue Canyon Technologies and Tendeg LLC, both in Colorado. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

Just Keep Roving
Image from Perseverance’s Right Navigation Camera, looking back towards rover tracks from past drives, into Jezero crater. The camera is located high on the rover mast, and here the rover is looking back in the direction of the Jezero crater floor. This image was acquired on October 4th, 2024 (Sol 1288) at the local mean solar time of 12:51:26. NASA/JPL-Caltech Throughout the past week, Perseverancehas continued marching up the Jezero crater rim. This steep ascent through the Martian regolith (soil) can prove to be slow driving for the rover, as the wheels can slip on the steepest areas. This is like trying to run up a hill of sand on a beach – with every step forward, you also slip back a little way down the hill! This just means the Science and Engineering teams work together closely to plan slow and steady drives through this tricky terrain.
Driving through the Mount Ranier quadrangle, the team identified a relatively obstacle-free path to reach the crater rim which they designated Summerland Trail, aptly named from a very popular hiking trail that ascends Mount Ranier. Perseverance is trekking to the next waypoint near an outcrop of rocks called Pico Turquino, where the science team hopes to perform its next proximity science investigations with its instruments PIXL and back-online SHERLOC.
While roving along Summerland Trail, Perseverance is constantly observing the surrounding terrain. SuperCam and Mastcam-Z have been observing rocks on the ground and on a distant hill, called Crystal Creek. In addition, during this time Perseverance can put its eyes to the sky to make observations of the sun and atmosphere. Last week, the Mastcam-Z camera captured images of Phobos (one of Mars’ two moons) transiting in front of the sun!
This image, showing Phobos transiting in front of the sun, was acquired using Perseverance’s Left Mastcam-Z camera. Acquired on September 30th, 2024 (Sol 1285) at the local mean solar time of 11:10:04. NASA/JPL-Caltech/ASU While the Mars2020 team is itching to reach the ancient stratigraphy exposed in the crater rim, for now, the focus is on documenting our surroundings while navigating the ascent.
