In today’s wrapup of technology and science news:

  • New 2-camera iPhone?
  • Jupiter up close (+ video)
  • Scouring SpaceX data
  • Leslie Jones tweets again

The details:

  • Dual camera iPhone?

Apple isn’t saying much about its next iPhones, but there’s been plenty of speculation that the giant Plus model will have two camera lenses side by side on the back.

Why? A second lens could make photos sharper or give amateur shutterbugs blurring techniques more common in full-bodied SLR cameras. Apple isn’t revealing anything until its product event in San Francisco on Wednesday. For now, though, people can look at how a few other smartphone makers are using two lenses.

The tech giant announced the date for the Sept. 7 launch by sending out invitations to technology journalists and industry analysts on Monday.

Apple didn’t provide any details, in keeping with its usual practice, but it traditionally announces one or two new iPhone models at its annual September event. Apple may also show new models or features for other products like the Apple Watch or Macbook computer.

Apple sold more than 214 million iPhones over the last 12 months. But sales are down from a year ago, and analysts will be watching closely to see what changes Apple has made in the newest models.

  • Up close to Jupiter

A NASA spacecraft has captured the best views of Jupiter yet, revealing turbulent storms in the north pole.

Jupiter’s northern polar region is stormier than expected and appears bluer than the rest of the planet, said mission chief scientist Scott Bolton of the Southwest Research Institute in San Antonio.

“This image is hardly recognizable as Jupiter,” he said in a statement.

NASA on Friday released a batch of close-up pictures taken by the Juno spacecraft last week when it flew within 2,500 miles of Jupiter’s dense cloud tops.

During the rendezvous that took Juno from pole to pole, the solar-powered spacecraft turned on its camera and instruments to collect data.

The first glimpse of Jupiter’s poles came in 1974 when Pioneer 11 flew by on its way to Saturn.

The detailed pictures taken by Juno look “like nothing we have seen or imagined before,” Bolton said.

Juno also sent back unique views of Jupiter’s bright southern lights considered the most powerful in the solar system.

The flyby was the first of three dozen planned close passes during the 20-month mission.

Unlike rocky Earth and Mars, Jupiter is a gas giant that likely formed first, shortly after the sun. Studying the largest planet in the solar system may hold clues to understanding how Earth and the rest of the planets formed.

After a five-year journey, Juno slipped into orbit around Jupiter in July to map the massive planet’s poles, atmosphere and interior. It’s the first spacecraft to carry a titanium vault designed to shield its computer and electronics from intense radiation.

Juno is only the second mission to orbit Jupiter. When it completes its job in 2018, it will deliberately crash into Jupiter’s atmosphere and disintegrate. NASA planned the finale so that Juno won’t accidentally smack into Jupiter’s moons, particularly the icy moon Europa, a target of future exploration.

  • SpaceX scours for cause of explosion

SpaceX is scouring computer and video data for clues to the devastating launch pad explosion that destroyed a rocket and satellite.

Thursday’s accident occurred during a prelaunch test, eight minutes before the engines on SpaceX’s Falcon rocket were supposed to briefly fire. The rocket was being fueled when a huge fireball erupted.

On Friday, SpaceX said it has begun reviewing 3,000 channels of computer and video data, covering a time period of just 35 to 55 milliseconds. The trouble appears to have originated somewhere near the liquid oxygen tank in the upper stage.

SpaceX said it’s unclear how badly the pad was damaged at Cape Canaveral Air Force Station. But the company pointed out that it has two other pads, one at neighboring Kennedy Space Center that was formerly used to launch NASA’s shuttles, and another in California. SpaceX said these two pads can support the company’s upcoming launches, until the damaged complex can be fixed.

The Kennedy pad should be ready to handle Falcon launches as early as November, according to SpaceX. That’s the site where the company plans to launch NASA astronauts to the International Space Station in another year or so, a schedule now in jeopardy. Upgrades at the SpaceX pad at California’s Vandenberg Air Force Base are close to completion.

  • Leslie Jones returns to Twitter

Undeterred by the hacking of her personal website, Leslie Jones returned to Twitter to pledge that she will “always get back up.”

The “Ghostbusters” star had been harassed with racist messages on social media and her website was hacked in late August. She has since stayed quiet but on Saturday night, she began tweeting again, voicing, among other things, her love for “The Golden Girls.”

On Sunday, she told concerned fans “I’m sooooo OK, really.” She added that she “will always be funny.”

Jones said that she’s been through a lot in her life “and I will always get back up.”
