NASA aims to make a second attempt to launch its giant next-generation moon rocket on Saturday, Sept. 3, five days after a pair of technical issues foiled an initial try at getting the spacecraft off the ground for the first time, agency officials said on Tuesday.

But prospects for success on Saturday appeared clouded by weather reports predicting just a 40% chance of favourable conditions that day, while the US space agency acknowledged some outstanding technical issues remain to be solved.

At a media briefing a day after Monday’s first countdown ended with the flight scrubbed, NASA officials said Monday’s experience was useful in trouble-shooting some problems and that additional difficulties could be worked through in the midst of a second launch try.

In that way, the launch exercise was serving essentially as a real-time dress rehearsal that hopefully would conclude with an actual, successful liftoff.

For now, NASA officials said, plans call for keeping the 32-story-tall Space Launch System (SLS) rocket and its Orion astronaut capsule on its launch pad to avoid having to roll the massive spacecraft back into its assembly building for a more extensive round of tests and repairs.

If all goes as hoped, the SLS will blast off from the Kennedy Space Center in Cape Canaveral, Florida, on Saturday afternoon, during a two-hour launch window that opens at 2:17 pm, sending the Orion on an uncrewed, six-week test flight around the moon and back.

The long-awaited voyage would kick off NASA’s moon-to-Mars Artemis program, the successor to the Apollo lunar project of the 1960s and ’70s before US human spaceflight efforts shifted to low-Earth orbit with space shuttles and the International Space Station.

NASA’s initial Artemis I launch attempt on Monday ended after data showed that one of the rocket’s main-stage engines failed to reach the proper pre-launch temperature required for ignition, forcing a halt to the countdown and a postponement.

Speaking to reporters on Tuesday, mission managers said they believe a faulty sensor in the rocket’s engine section was the culprit for the engine cooling issue.

As a remedy for Saturday’s attempt, mission managers plan to begin that engine-cooling process roughly 30 minutes earlier in the launch countdown, NASA’s Artemis launch director Charlie Blackwell-Thompson said. But a full explanation for the faulty sensor requires more data analysis by engineers.

“The way the sensor is behaving doesn’t line up with the physics of the situation,” said John Honeycutt, NASA’s SLS program manager.

The sensor was last checked and calibrated months ago in the rocket factory, Honeycutt said. Replacing the sensor would require rolling the rocket back to its assembly building, a process that could delay the mission for months.

The first voyage of the SLS-Orion, a mission dubbed Artemis I, aims to put the 5.75-million-pound vehicle through its paces in a rigorous demonstration flight pushing its design limits before NASA deems it reliable enough to carry astronauts.

Named for the goddess who was Apollo’s twin sister in ancient Greek mythology, Artemis seeks to return astronauts to the moon’s surface as early as 2025, though many experts believe that the time frame will likely slip by a few years.

The last humans to walk on the moon were the two-man descent team of Apollo 17 in 1972, following in the footsteps of 10 other astronauts during five earlier missions beginning with Apollo 11 in 1969.

Artemis also is enlisting commercial and international help to eventually establish a long-term lunar base as a stepping stone to even more ambitious human voyages to Mars, a goal NASA officials say would probably take until at least the late 2030s to achieve.

But NASA has many steps to take along the way, starting with getting the SLS-Orion vehicle into space.

WATCH: Google search engine shows off creative doodle to celebrate 25th anniversary

Over 25 years ago, a unique concept for an internet search engine that would classify and rank web pages was developed by two Stanford University students during a brainstorming session in their dorm.

BackRub, initially a startup, transformed into Google, a globally influential company with products like Gmail and Search used by billions, while its co-founders Larry Page and Sergey Brin ranked among the world’s richest people.

While Google Inc was incorporated on September 4, for more than a decade the company has celebrated its birthday on September 27 with unique doodles displayed on its search engine.

However, this year, Google Inc decided to take a “walk down memory lane” and showcased a series of creative different doodles, including doodles of previous logos, to mark this special occasion.

This year’s Google Doodle comes with a GIF that shows the term ‘Google’ going through a series of transformations before finally transforming to ‘G25gle’.

The tech giant said that it was using this day as a “time to reflect” while being oriented towards the future.

“Today’s Doodle celebrates Google’s 25th year. And while here at Google we’re oriented towards the future, birthdays can also be a time to reflect. Let’s take a walk down memory lane to learn how we were born 25 years ago,” Google wrote in its blog.

Google was founded by Sergey Brin and Larry Page in the late 90s, who met in Stanford University’s computer science program.

They shared a vision to make the World Wide Web more accessible, working tirelessly from their dorm rooms to develop a better search engine prototype.

“As they made meaningful progress on the project, they moved the operation to Google’s first office — a rented garage. On September 27, 1998, Google Inc was officially born,” according to the blog.

Furthermore, the company emphasised that much has changed since 1998, but also said that its mission has remained the same which is “to organise the world’s information and make it universally accessible and useful”.

Thanking users for “evolving with us over the past 25 years,” Google added, “We can’t wait to see where the future takes us, together”.

Google’s CEO, Sundar Pichai, celebrated the company’s birthday by reflecting on its journey in a note last month.

He looked back on the company’s role in technology transformation, and its future path while thanking users, employees, and partners for their contributions to Google’s success.

He also praised the constant innovation challenge and commended the dedication of past and present Googlers.

In his note, Pichai also noted the importance of innovation and adaptation, acknowledging that the once extraordinary technology quickly became ordinary as the boundaries continued to be pushed, NDTV reported.

Apple sends iPhone 12 update to French authorities to address radiation concerns

French authorities have received a software update from Apple for its iPhone 12 in response to concerns about radiation levels, according to a source at the French digital ministry.

The update is currently under review as a potential solution to the radiation issue. France had recently suspended the sale of iPhone 12 devices after tests revealed breaches of radiation exposure limits.

Apple had initially contested these findings, asserting that the iPhone 12 complied with global standards as certified by multiple international bodies. However, the company later decided to issue a software update to align with the testing methods used in France.

Apple’s decision to provide the software update came after France threatened to seek a product recall if the company did not take action. The update aims to address the specific concerns raised by French authorities regarding radiation levels.

While the World Health Organization has not established adverse health effects caused by mobile phones, the radiation warning in France was based on test results that differed from those conducted in other countries. Industry experts have emphasised that there are no safety risks, as regulatory limits are set well below levels associated with harm.

The software update for the iPhone 12 is a routine measure taken by Apple to address specific issues or improve device performance. It is part of the company’s ongoing commitment to providing software updates for its products. Apple users typically receive notifications for eligible software updates, which they can then install.

French authorities and regulators in other countries are closely monitoring the situation, and Italian authorities are awaiting the outcome of France’s deliberations before making a decision.

The software update is expected to bring the iPhone 12 into compliance with the radiation exposure limits specified by French testing methods. Apple has not issued an official statement regarding the update at the time of this report.
