Boeing’s 1st astronaut flight to space delayed until July

Boeing’s first launch of astronauts has been delayed again, this time until July.

NASA announced the latest postponement Wednesday, saying more time is needed to certify and test the Starliner capsule’s parachute system before the spacecraft blasts off with two test pilots. Additional software testing is also underway, AP reported.

Boeing already was running years behind schedule when it had to repeat its test flight without a crew to International Space Station because of software and other problems. The first was in 2019 and the second in 2022.

“We know that what we’re doing is extremely important, launching humans in space,” Boeing’s Mark Nappi told reporters. “So we’ll take our time and we’ll make sure that everybody is confident with the work that’s been done.”

Liftoff is currently targeted for no earlier than July 21 from Cape Canaveral Space Force Station. The Starliner capsule will ride atop United Launch Alliance’s Atlas V rocket.

NASA hired Boeing and SpaceX a decade ago to ferry astronauts to and from the space station. SpaceX launched its seventh NASA crew earlier this month.

Gmail is adding more AI to help you find important emails faster

Google is building AI into its products faster than most with Gmail becoming the latest Google app to get an injection of artificial intelligence, to improve search results on mobile.

“When searching in Gmail, machine learning models will use the search term, most recent emails and other relevant factors to show you the results that best match your search query,” Google explains in a blog post.

“These results will now appear at the top of the list in a dedicated section, followed by all results sorted by recency,” the post continues. In other words, AI will (in theory) pick out the best matches for your search, and put them at the top of the list, Tech Radar reports.

This is coming to the Gmail apps for Android and iOS, and should be rolling out for everyone now. As yet, there’s no word on whether or not the same feature will be making an appearance in the desktop web interface for Gmail.

AI has been built into Gmail for years of course, with features like Smart Reply composing short automated replies for you but in recent months, Google has been pushing more advanced, generative AI as a way of composing your emails.

More AI features are heading to search on the web too, while development on the ChatGPT rival Google Bard continues at a steady pace.

Scientists expand search for signs of intelligent alien life

Scientists have expanded the search for technologically advanced extraterrestrial civilizations by monitoring a star-dense region toward the core of our galaxy for a type of signal that could be produced by potential intelligent aliens that until now has been ignored.

Efforts to detect alien technological signatures previously have focused on a narrowband radio signal type concentrated in a limited frequency range or on single unusual transmissions. 

The new initiative, scientists said this week, focuses on a different signal type that perhaps could enable advanced civilizations to communicate across the vast distances of interstellar space, Reuters reported.

These wideband pulsating signals for which the scientists are monitoring feature repetitive patterns – a series of pulses repeating every 11 to 100 seconds and spread across a few kilohertz, similar to pulses used in radar transmission. The search involves a frequency range covering a bit less than a tenth the width of an average FM radio station.

“The signals searched in our work would belong to the category of deliberate ‘we are here’ type beacons from alien worlds,” said Akshay Suresh, a Cornell University graduate student in astronomy and lead author of a scientific paper published in the Astronomical Journal describing the new effort.

“Aliens may possibly use such beacons for galaxy-wide communications, for which the core of the Milky Way is ideally placed. One may imagine aliens using such transmissions at the speed of light to communicate key events, such as preparations for interstellar migration before the explosive death of a massive star,” Suresh added.

The effort, called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), is a collaboration between Cornell, the SETI Institute research organization and Breakthrough Listen, a $100 million initiative to search for advanced extraterrestrial life.

Using a ground-based radio telescope in West Virginia, BLIPSS has focused upon a sliver of the sky less than one-200th of the area covered by the moon, stretching toward the center of the Milky Way roughly 27,000 light years away. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

This area contains about 8 million stars, Suresh said. If extraterrestrial life forms exist, they presumably would populate rocky planets orbiting in what is called the habitable zone, or Goldilocks zone, around a star – not too hot and not too cold.

The scientists in the various monitoring efforts passively scan for signals of alien beings and do not actively send their own signals advertising our presence on Earth.

No aliens yet have been detected in the monitoring efforts.

Boeing’s astronaut capsule faces more launch delays after latest problems

Boeing’s astronaut capsule faces more launch delays after the discovery of problems that should have been caught earlier, AP reported. 

Boeing and NASA announced the latest setback Thursday.

Until recently, the Starliner capsule was on track for a July test flight with two astronauts to the International Space Station, a planned trip that was already well behind schedule.

But final reviews uncovered issues with the parachute lines and other problems that were present on last year’s test flight with no one on board and, officials said, should have been caught years ago.

As for whether Starliner might fly by year’s end, Boeing program manager Mark Nappi said, “I think it’s feasible, but I certainly don’t want to commit to any dates or time frames” until the problems are fixed.

The capsule is full of wire harnesses wrapped in white tape that’s flammable, according to Nappi. Rather than trying to remove the hundreds of feet of tape, which was supposed to protect against scuffing, the company may cover it with a safer material.

The parachute lines also were not designed to be strong enough to meet safety standards.

“These tests were run many years ago. We reviewed those results. We missed those results, and this could have been caught sooner,” Nappi said.

Following the retirement of the space shuttles more than a decade ago, NASA hired Boeing and SpaceX to transport astronauts to and from the space station. SpaceX has now completed 10 crew flights, three of them private. Boeing had to repeat its 2019 test flight without a crew because of software and other issues.

“NASA desperately needs a second provider for crew transportation,” said Steve Stich, the space agency’s commercial crew program manager.

The goal is to have one SpaceX and one Boeing taxi flight to the station each year.
