A lack of effective radiation shielding is one of the biggest challenges still to be overcome if humans are to embark on long-term voyages into deep space. On Earth, the planet’s powerful magnetosphere protects us from the deadliest forms of radiation – those produced by solar flares, and galactic cosmic rays arriving from afar – that stream through the Solar System. Astronauts on the International Space Station, some 408km above the Earth, receive elevated levels of radiation, but are close enough to Earth that they still receive some shielding, and can stay on orbit for up to a year. The same can’t be said for astronauts traveling further out, to the Moon, for example, or, someday, to Mars. Future deep space voyagers will need to bring their own shielding with them – or, as a new paper suggests – grow it along the way.

The latest satellite in the Landsat family of Earth observation spacecraft has collected its “first light” images of our planet. Landsat 9 launched on September 27, 2021 and it continues the nearly 50-year tradition of making critical observations to help with energy and water management, forest monitoring, human and environmental health, urban planning, disaster recovery and agriculture.

The Hubble Space Telescope has been in ‘safe mode’ since October 23, with all of the science instruments offline and unavailable for observations. However, engineers have now been able to bring one instrument, the Advanced Camera for Surveys (ACS), back online, and have restarted its science observations. NASA said engineers are still investigating the issue as the other four instruments remain offline.

Two microphones aboard the Perseverance Rover have recorded “alien” sounds on Mars – the sounds of a human-made spacecraft crunching its wheels on the Red Planet’s surface, or its motors whirring, or blasts from its scientific laser instrument. Perseverance’s microphones have also captured the sounds of another spacecraft – the Ingenuity helicopter – taking flight. During the five or so hours recorded so far, you can hear the Martian wind gusting in the background.
“We’ve been able to see Mars from the rovers’ point of view for a quite a long time now,” said Greg Delory, a consultant to the Mars 2020 rover microphone team, “so to have another ‘sense’ on Mars is pretty incredible.”

NASA has pushed back the timetable for landing astronauts on the moon for the first time in more than a half-century from 2024 to no earlier than 2025.
Blue Origin’s unsuccessful legal challenge to a $2.9 billion lunar lander contract awarded to SpaceX was one of the factors behind the delay in the Artemis moon program, NASA Administrator Bill Nelson said during a Nov. 9 teleconference.
Nelson also pointed to Congress’ previous decisions not to fund the lander program as fully as NASA wanted, plus delays forced by the COVID-19 pandemic and the fact that “the Trump administration target of a 2024 human landing was not grounded in technical feasibility.”
“After having taken a good look under the hood these past six months, it’s clear to me that the agency will need to make serious changes for the long-term success of the program,” he told reporters.

Four astronauts splashed down safely in the Gulf of Mexico aboard their SpaceX Crew Dragon Endeavour capsule, despite one of the parachutes not deploying immediately. Their spectacular return in darkness from the International Space Station capped off the record-setting mission for the SpaceX Crew-2, with the longest spaceflight by a U.S. crewed spacecraft. Their 199 days in orbit surpassed the 168 days set by NASA’s SpaceX Crew-1 mission earlier this year.
