    NASA, Boeing Modify Commercial Crew Contract

    In 2014, NASA awarded a Commercial Crew Transportation Capability contract to Boeing to fly astronauts to and from the International Space Station with its Starliner spacecraft. As part of its contract, Boeing was awarded up to six crewed flights to the orbital complex. After a thorough evaluation, NASA and Boeing have mutually agreed to modify […]

    Week Wraps with Fluid Physics, Stem Cell Research as New Crew Preps Begin

    Expedition 73 wrapped up the work week continuing to study fluid physics and stem cells, preparing for next week’s new crew arrival, and unpacking a U.S. cargo spacecraft. The International Space Station residents also serviced exercise gear, performed life support system troubleshooting, and analyzed the orbital outpost’s microbial environment.

    Station Orbiting Higher as Exercise Research and Maintenance Continue

    The International Space Station is orbiting higher today after the Progress 93 cargo spacecraft, docked to the Zvezda service module’s aft port, fired its engines for over 14 minutes, 7 seconds at 8:04 a.m. EST on Wednesday. Back on the orbital outpost, the Expedition 73 crew focused its science activities on exercise research and fluid physics, both benefitting humans living on and off the Earth.

    NASA’S STEREO Observes Interstellar Comet 3I/ATLAS

    The image is made up of vertical streaks of black and various hues of pinks with a hazy white orb at the center, representing the comet 3I/ATLAS. The top left corner has the name of the comet, 3I/ATLAS, and below that, the date range the comet was observed.

    NASA’s STEREO (Solar Terrestrial Relations Observatory) observed interstellar comet 3I/ATLAS from Sept. 11 to Oct. 2. The STEREO mission, designed to study the Sun’s activity and its influence across the solar system, is part of a fleet of NASA spacecraft observing this comet, together providing more information about its size, physical properties, and chemical makeup. […]

    NASA/ESA’s SOHO Observes Interstellar Comet 3I/ATLAS

    A faint, slightly yellowish point of light—Comet 3I/ATLAS—appears near the center of a grainy, brown-toned background captured by the SOHO/LASCO C3 coronagraph between October 15–26, 2025. The comet is only marginally brighter than the surrounding noise, making it difficult to distinguish.

    The ESA (European Space Agency) and NASA Solar and Heliospheric Observatory, or SOHO, spacecraft captured a glimpse of interstellar comet 3I/ATLAS on Oct. 15–26. During this time period, the spacecraft’s Large Angle and Spectrometric Coronagraph (LASCO) instrument suite spotted the comet crossing its field of view from approximately 222 million miles (358 million kilometers) away, […]

    NASA’s PUNCH Spies Interstellar Comet 3I/ATLAS

    A round, white object appears at the center of a black-and-white image, with a short tail-like feature extending to the right. Fuzzy black, white, and gray diagonal, parallel stripes fill the background.

    NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission observed interstellar comet 3I/ATLAS during its passage through the inner solar system. The mission’s ability to observe areas of the sky near the Sun allowed PUNCH to track the comet as it passed close to our star, when few other observatories could. This image was created from multiple observations taken […]

    NASA’s Lucy Spacecraft Snaps Photos of Interstellar Comet 3I/ATLAS

    A comet in the middle of a star field with a faint tail extending to the right.

    Lucy’s high-resolution, black-and-white imager, L’LORRI, captured a series of photos between Sept. 15–17, as the comet was zooming toward Mars. Lucy was 240 million miles away from 3I/ATLAS, well beyond the orbit of Mars, on its way to explore eight asteroids out of two swarms of asteroids that share an orbit with Jupiter, collectively known as the Jupiter Trojan asteroids.

    Heart Health, Stem Cells, and Physics Keep Crew Busy on Tuesday

    Life science and physics topped the research schedule aboard the International Space Station on Tuesday as the Expedition 73 crew studied heart health, stem cells, fluid physics, and spacecraft fire safety. The orbital residents also completed work on a spacesuit and inspected ventilation and electrical systems while continuing other scientific operations.

    Monday’s Research Studies Ways to Protect Eyes and Lungs in Space

    Expedition 73 kicked off the week exploring how to prevent space-caused vision problems and what happens to the respiratory system in microgravity. The International Space Station residents also worked on combustion research and Earth observation gear, organized food and cargo inventory, and serviced life support systems.
