Artemis Astronauts Enter Moon's Gravitational Pull, Catch First Glimpses of Far Side

1 month 1 week ago
NASA's Artemis astronauts are now entering "the lunar sphere of influence," reports NBC News, "meaning the pull of the moon's gravity will become stronger than Earth's." Now as they begin their swing around the moon, the Artemis astronauts "are chasing after Apollo 13's maximum range from Earth," reports the Associated Press, hoping to beat its distance from Earth by more than 4,100 miles (6,600 kilometers). They'll begin their six-hour lunar flyby 14 hours from now (at 2:45 p.m. ET Monday). But in a space-to-earth interview Saturday with NBC News, the astronauts were already describing their first glimpses of the edge of the far side: [NASA astronaut Christina Koch realized] it looked different from what she was accustomed to on Earth. "The darker parts just aren't quite in the right place," she said. "And something about you senses that is not the moon that I'm used to seeing...." [Astronaut Reid] Wiseman called the flight a "magnificent accomplishment" and said the astronauts' ability to gaze at both Earth and the moon from their spacecraft has been "truly awe-inspiring." "The Earth is almost in full eclipse. The moon is almost in full daylight, and the only way you could get that view is to be halfway between the two entities," he said... And while the early photos of Earth and the moon that [Canadian astronaut Jeremy] Hansen and his colleagues have beamed back have been spectacular, the Canadian astronaut said they pale in comparison to the real deal outside their capsule's windows. "I know those photos are amazing," he said, "but let me assure you, it is another level of amazing up here." And their upcoming six-hour lunar flyby "promises views of the moon's far side that were too dark or too difficult to see by the 24 Apollo astronauts who preceded them," notes the Associated Press: A total solar eclipse also awaits them as the moon blocks the sun, exposing snippets of shimmering corona.... At closest approach, they will come within 4,070 miles (6,550 kilometers) of the moon. Because they launched on April 1, the rendezvous won't have as much of the far lunar side illuminated as other dates would have. But the crew still will be able make out "definite chunks of the far side that have never been seen" by humans, said NASA geologist Kelsey Young, including a good portion of Orientale Basin. They'll call down their observations as they photograph the gray, pockmarked scenes. There's a suite of professional-quality cameras on board, and each astronaut also has an iPhone for more informal, spur-of-the-minute picture-taking... Orion will be out of contact with Mission Control for nearly an hour when it's behind the moon. The same thing happened during the Apollo moonshots. NASA is relying on its Deep Space Network to communicate with the crew, but the giant antennas in California, Spain and Australia won't have a direct line of sight when Orion disappears behind the moon for approximately 40 minutes... Once Artemis II departs the lunar neighborhood, it will take four days to return home. The capsule will aim for a splashdown in the Pacific near San Diego on April 10, nine days after its Florida launch. During the flight back, the astronauts will link up via radio with the crew of the orbiting International Space Station. This is the first time that a moon crew has colleagues in space at the same time and NASA can't pass up the opportunity for a cosmic chitchat.

Internet Bug Bounty Pauses Payouts, Citing 'Expanding Discovery' From AI-Assisted Research

1 month 1 week ago
The Internet Bug Bounty program "has been paused for new submissions," they announced last week. Running since 2012, the program is funded by "a number of leading software companies," reports InfoWorld, "and has awarded more than $1.5m to researchers who have reported bugs " Up to now, 80% of its payouts have been for discoveries of new flaws, and 20% to support remediation efforts. But as artificial intelligence makes it easier to find bugs, that balance needs to change, HackerOne said in a statement. "AI-assisted research is expanding vulnerability discovery across the ecosystem, increasing both coverage and speed. The balance between findings and remediation capacity in open source has substantively shifted," said HackerOne. Among the first programs to be affected is the Node.js project, a server-side JavaScript platform for web applications known for its extensive ecosystem. While the project team will continue to accept and triage bug reports through HackerOne, without funding from the Internet Bug Bounty program it will no longer pay out rewards, according to an announcement on its website... [J]ust last month, Google also put a halt to AI-generated submissions provided to its Open Source Software Vulnerability Reward Program. The Internet Bug Bounty stressed that "We have a responsibility to the community to ensure this program effectively accomplishes its ambitious dual purpose: discovery and remediation. Accordingly, we are pausing submissions while we consider the structure and incentives needed to further these goals..." "We remain committed to strengthening open source security. Working with project maintainers and researchers, we're actively evaluating solutions to better align incentives with open source ecosystem realities and ensure vulnerability discoveries translate into durable remediation outcomes."
