Lacking an atmosphere despite its large size, Ganymede is especially vulnerable to a hostile space environment.
Observations of Ganymede, Jupiter’s largest moon, in July were focused on an icy surface believed to overlay vast oceans and a magnetic field. NASA’S Juno probe creates stunning map of Jupiter’s largest moonįuturism (8/11): Launched in August 2011, NASA’s Juno mission achieved orbit around Jupiter in July 2016 for long term, close-up observations of the solar system’s largest planet and its many moons. NASA is joining with the European Space Agency (ESA) to return more than 30 samples collected by Perseverance for studies that could reveal whether the Red Planet once hosted biological activity. Perseverance will now travel to a new site for a second collection attempt, one that scientists believe will provide a more compatible rock sample coring opportunity. The collection attempt by drilling into a rock sample was attempted at the end of last week. NASA blames Mars rover sampling fiasco on bad, powdery rockĪssociated Press (8/11): NASA’s Perseverance mission scientists and engineers believe the powdery nature of the Martian rock at the rover’s Jezero Crater landing site prevented the rover from collecting a much anticipated first rock sample. Its orbital course will be closely monitored. Bennu presents only a slight risk, just 1/2700 chance during encounters with the Earth through 2300. OSIRIS-REx’s stay in proximity to Bennu between December 2018 and May 2021 is also helping experts assess the impact risks that near-Earth objects (NEO) pose to the Earth. (8/11): Launched in 2016, NASA’s OSIRIS-REx mission is on its way back to Earth to drop off samples of the asteroid Bennu in September 2023. Scientists fine-tune odds of asteroid Bennu hitting Earth through 2300 with NASA probe’s help The RS-25 engine, made by the California-based aerospace company Aerojet Rocketdyne, was fired at NASA’s Stennis Space Center in Mississippi for 500 seconds (more than eight minutes) to duplicate the time it will take four engines to boost the first stage of the massive SLS rocket.
(8/11): On Thursday, August 5, NASA finished its sixth RS-25 engine hot-fire test for the missions that would come after the fourth Artemis flight. Watch NASA fire up its SLS rocket engines to test far-out mission technologies (video)Ĭoalition Member in the News – Aerojet Rocketdyne DeMauro said Cygnus has become more than just a cargo transport, already seeing its technology incorporated into the HALO habitation module for NASA’s upcoming Lunar Gateway station. Speaking before the berthing, Northrop Grumman’s Frank DeMauro discussed future Cygnus missions to the ISS as well as non-ISS uses for the craft. EDT, as it approached for docking with the ISS’s U.S. (8/12): Northrop Grumman’s 16th resupply mission spacecraft successfully reached the International Space Station (ISS) early Thursday. NASA astronaut Megan McArthur commanded the ISS’s Canadian robotic arm to grapple the Cygnus freighter at 6:07 a.m. NG-16 arrives at ISS, Northrop Grumman talks Cygnus’ future useĬoalition Member in the News – Northrop Grumman In Today’s Deep Space Extra… Perseverance rover scientists blame the powdery nature of Mars rock for last week’s failed first sample collection attempt.
