NASA launches newest robotic explorer to moon
The LADEE spacecraft, which is charged with studying the lunar atmosphere and dust, soared aboard an unmanned Minotaur rocket a little before midnight, dazzling spectators along the East Coast.
“Godspeed on your journey to the moon, LADEE,” Launch Control said.
Flight controllers applauded and exchanged high-fives following the successful launch. “We are headed to the moon!” NASA said in a tweet.
It was a change of venue for NASA, which normally launches moon missions from Cape Canaveral, Florida But it provided a rare light show along the East Coast for those blessed with clear skies.
NASA expected the launch from Virginia’s Eastern Shore to be visible, weather permitting, as far south as South Carolina, as far north as Maine and as far west as Pittsburgh.
The space agency urged sky watchers to share their launch pictures through the website Flickr, and the photos quickly poured in from New York City, Boston, Washington, D.C., Baltimore, New Jersey, Rhode Island, eastern Pennsylvania and Virginia, among other places.
The Lunar Atmosphere and Dust Environment Explorer or LADEE, pronounced “LA’-dee,” is taking a roundabout path to the moon, making three huge laps around Earth before getting close enough to pop into lunar orbit.
Unlike the quick three-day Apollo flights to the moon, LADEE will need a full month to reach Earth’s closest neighbor. An Air Force Minotaur V rocket, built by Orbital Sciences Corp., provided the ride from NASA’s Wallops Flight Facility.
LADEE, which is the size of a small car, is expected to reach the moon on Oct. 6.
Scientists want to learn the composition of the moon’s ever-so-delicate atmosphere and how it might change over time. Another puzzle, dating back decades, is whether dust actually levitates from the lunar surface.
The $280 million moon-orbiting mission will last six months and end with a suicide plunge into the moon for LADEE.
The 844-pound (380-kilogram) spacecraft has three science instruments as well as laser communication test equipment that could revolutionize data relay. NASA hopes to eventually replace its traditional radio systems with laser communications, which would mean faster bandwidth using significantly less power and smaller devices.
“There’s no question that as we send humans farther out into the solar system, certainly to Mars,” that laser communications will be needed to send high-definition and 3-D video, said NASA’s science mission chief, John Grunsfeld, a former astronaut who worked on the Hubble Space Telescope.
It was a momentous night for Wallops, which was making its first deep-space liftoff. All of its previous launches were confined to Earth orbit.
NASA chose Wallops for LADEE because of the Minotaur V rocket, comprised of converted intercontinental ballistic missile motors belonging to the Air Force. A US-Russian treaty limits the number of launch sites because of the missile parts.
All but one of NASA’s previous moon missions since 1959, including the manned Apollo flights of the late 1960s and early 1970s, originated from Cape Canaveral. The most recent were the twin Grail spacecraft launched almost exactly two years ago. The military-NASA Clementine rocketed away from Southern California in 1994.
Wallops will be back in the spotlight in less than two weeks. The Virginia-based Orbital Sciences will make its first delivery to the International Space Station, using its own Antares rocket and Cygnus capsule. That commercial launch is scheduled for Sept. 17.
Instagram unveils new video service in challenge to YouTube
- Video will be available through Instagram or a new app called IGTV
- Before, Facebook and Instagram have copied Snapchat — another magnet for teens and young adults
SAN FRANCISCO: Facebook’s Instagram service is loosening its restraints on video in an attempt to lure younger viewers away from YouTube when they’re looking for something to watch on their smartphones.
The expansion announced Wednesday, dubbed IGTV, will increase Instagram’s video time limit from one minute to 10 minutes for most users. Accounts with large audiences will be able to go as long as an hour.
Video will be available through Instagram or a new app called IGTV. The video will eventually give Facebook more opportunities to sell advertising.
It’s the latest instance in which Instagram has ripped a page from a rival’s playbook in an effort to preserve its status as a cool place for young people to share and view content. In this case, Instagram is mimicking Google’s YouTube. Before, Facebook and Instagram have copied Snapchat — another magnet for teens and young adults.
Instagram, now nearly 8 years old, is moving further from its roots as a photo-sharing service as it dives headlong into longer-form video.
The initiative comes as parent company Facebook struggles to attract teens, while also dealing with a scandal that exposed its leaky controls for protecting users’ personal information.
Instagram CEO Kevin Systrom told The Associated Press that he hopes IGTV will emerge as a hub of creativity for relative unknowns who turn into Internet sensations with fervent followings among teens and young adults.
That is what’s already happening on YouTube, which has become the world’s most popular video outlet since Google bought it for $1.76 billion nearly 12 years ago. YouTube now boasts 1.8 billion users.
Instagram, which Facebook bought for $1 billion six years ago, now has 1 billion users, up from 800 million nine months ago.
More importantly, 72 percent of US kids ranging from 13 to 17 years old use Instagram, second to YouTube at 85 percent, according to the Pew Research Center. Only 51 percent of people in that group now use Facebook, down from 71 percent from a similar Pew survey in 2014-15.
That trend appears to be one of the reasons that Facebook is “hedging its bets” by opening Instagram to the longer-form videos typically found on YouTube, said analyst Paul Verna of the research firm eMarketer.
Besides giving Instagram another potential drawing card, longer clips are more conducive for video ads lasting from 30 seconds to one minute. Instagram doesn’t currently allow video ads, but Systrom said it eventually will. When the ads come, Instagram intends to share revenue with the videos’ creators — just as YouTube already does.
“We want to make sure they make a living because that is the only way it works in the long run,” Systrom said.
The ads also will help Facebook sustain its revenue growth. Total spending on online video ads in the US is expected to rise from nearly $18 billion this year to $27 billion in 2021, according to eMarketer.
Lele Pons, a YouTube sensation who also has amassed 25 million followers on Instagram, plans to launch a new cooking show on IGTV in hopes of increasing her audience and eventually generating more revenue. “It’s like Coca-Cola and Pepsi,” she said. “You will never know what you like better unless you try both.”
IGTV’s programming format will consist exclusively of vertical video designed to fill the entire screen of smartphones — the devices that are emerging as the main way younger people watch video. By contrast, most YouTube videos fill only a portion of the screen unless the phone is tilted horizontally.
Snapchat began featuring vertical video before Instagram, another example of its penchant for copying rivals.
But Systrom sees it differently. “This is acknowledging vertical video is the future and we want the future to come more quickly, so we built IGTV.”
