Apollo 11 astronaut returns to launch pad 50 years later

  • President John F. Kennedy’s challenge to put a man on the moon by the end of 1969 took eight years to achieve

CAPE CANAVERAL, Florida: Apollo 11 astronaut Michael Collins returned Tuesday to the exact spot where he flew to the moon 50 years ago with Neil Armstrong and Buzz Aldrin.
Collins had the spotlight to himself this time — Armstrong has been gone for seven years and Aldrin canceled. Collins said he wished his two moonwalking colleagues could have shared the moment at Kennedy Space Center’s Launch Complex 39A, the departure point for humanity’s first moon landing.
“Wonderful feeling to be back,” the 88-year-old command module pilot said on NASA TV. “There’s a difference this time. I want to turn and ask Neil a question and maybe tell Buzz Aldrin something, and of course, I’m here by myself.”
At NASA’s invitation, Collins marked the precise moment — 9:32 a.m. on July 16, 1969 — that the Saturn V rocket blasted off. He was seated at the base of the pad alongside Kennedy’s director, Robert Cabana, a former space shuttle commander.
Collins recalled the tension surrounding the crew that day.
“Apollo 11 ... was serious business. We, crew, felt the weight of the world on our shoulders. We knew that everyone would be looking at us, friend or foe, and we wanted to do the best we possibly could,” he said.
Collins remained in lunar orbit, tending to Columbia, the mother ship, while Armstrong and Aldrin landed in the Eagle on July 20, 1969, and spent 2 ½ hours walking the gray, dusty lunar surface.
A reunion Tuesday at the Kennedy firing room by past and present launch controllers — and Collins’ return to the pad, now leased to SpaceX — kicked off a week of celebrations marking each day of Apollo 11’s eight-day voyage.
In Huntsville, Alabama, where the Saturn V was developed, some 4,900 model rockets lifted off simultaneously, commemorating the moment the Apollo 11 crew blasted off for the moon. More than 1,000 youngsters attending Space Camp counted down ... “5, 4, 3, 2, 1!” — and cheered as the red, white and blue rockets created a gray cloud, at least for a few moments, in the sky.
The US Space and Rocket Center was shooting for an altitude of at least 100 feet (30 meters) in order to set a new Guinness Book of World Records. Apollo 15 astronaut Al Worden helped with the mass launching. Also present: all three children of German-born rocket genius Wernher von Braun, who masterminded the Saturn V.
“This was a blast. This was an absolute blast,” said spectator Scott Hayek of Ellicott City, Maryland. “And, you know, what a tribute — and, a visceral tribute — to see the rockets going off.”
Another spectator, Karin Wise, of Jonesboro, Georgia, was 19 during Apollo 11 and recalled being glued to TV coverage.
“So, to bring my grandchildren here for the 50 anniversary, was so special,” she said. “I hope they’re around for the 100th anniversary.”
At the Smithsonian’s Air and Space Museum in Washington, the spacesuit that Armstrong wore went back on display in mint condition, complete with lunar dust left on the suit’s knees, thighs and elbows. On hand for the unveiling were Vice President Mike Pence, NASA Administrator Jim Bridenstine and Armstrong’s older son, Rick. Armstrong died in 2012.
A fundraising campaign took just five days to raise the $500,000 needed for the restoration. It was taken off display 13 years ago because it was deteriorating, said museum curator Cathleen Lewis. It took four years to rehab it.
Calling Armstrong a hero, Pence said “the American people express their gratitude by preserving this symbol of courage.”
Back at Kennedy, NASA televised original launch video of Apollo 11, timed down to the second. Then Cabana turned his conversation with Collins to NASA’s next moonshot program, Artemis, named after the twin sister of Greek mythology’s Apollo. It seeks to put the first woman and next man on the lunar surface — the moon’s south pole — by 2024. President John F. Kennedy’s challenge to put a man on the moon by the end of 1969 took eight years to achieve.
Collins said he likes the name Artemis and, even more, likes the concept behind Artemis.
“But I don’t want to go back to the moon,” Collins told Cabana. “I want to go direct to Mars. I call it the JFK Mars Express.”
Collins noted that the moon-first crowd has merit to its argument and he pointed out Armstrong himself was among those who believed returning to the moon “would assist us mightily in our attempt to go to Mars.”
Cabana assured Collins, “We believe the faster we get to the moon, the faster we get to Mars as we develop those systems that we need to make that happen.”
About 100 of the original 500 launch controllers and managers on July 16, 1969, reunited in the firing room Tuesday morning. The crowd also included members of NASA’s next moon management team, including Charlie Blackwell-Thompson, launch director for the still-in-development Space Launch System moon rocket. The SLS will surpass the Saturn V, the world’s most powerful rocket to fly to date.
Blackwell-Thompson said she got goosebumps listening to the replay of the Apollo 11 countdown. Hearing Collins’ “personal account of what that was like was absolutely amazing.”
The lone female launch controller for Apollo 11, JoAnn Morgan, enjoyed seeing the much updated- firing room. One thing was notably missing, though: stacks of paper. “We could have walked to the moon on the paper,” Morgan said.
Collins was reunited later Tuesday with two other Apollo astronauts at an evening gala at Kennedy, including Apollo 16 moonwalker Charlie Duke, who was the capsule communicator in Mission Control for the Apollo 11 moon landing. Only four of the 12 moonwalkers from 1969 through 1972 are still alive: Aldrin, Duke, Apollo 15’s David Scott and Apollo 17’s Harrison Schmitt.
Among the gala attendees: Eight former shuttle astronauts, including Mark Kelly and his wife, former US Rep. Gabrielle Giffords, astrophysicist Neil deGrasse Tyson and “space lover” and aspiring space tourist Vesa Heilala, 52, who traveled from Helsinki to Florida for the anniversary.
“I had to come here because in Finland we don’t have rockets and we don’t have astronauts for 50 years,” said Heilala, who was collecting astronaut autographs on his colorful propeller cap.
Huntsville’s rocket center also had a special anniversary dinner Tuesday night, with some retired Apollo and Skylab astronauts and rocket scientists. Aldrin was set to attend but was traveling Tuesday and likely wouldn’t make it on time, a center official said.
Aldrin, 89, hosted a gala in Southern California last Saturday.
NASA spokesman Bob Jacobs said Aldrin bowed out of the Florida launch pad visit, citing his intense schedule of appearances. Aldrin and Collins may reunite in Washington on Friday or Saturday, the 50th anniversary of Apollo 11’s moon landing.


Two engineers help fight Lebanese farming foe

Two engineers help fight Lebanese farming foe

  • Early-warning system lets farmers know when to protect their crops from fruit flies
  • Mobile app tells them the best time to spray pesticides to halt their advance

DUBAI: An award-winning startup led by two female Lebanese engineers has created an automated early-warning system that allows Middle East farmers to protect their crops against the Mediterranean fruit fly, one of the world’s most destructive pests.

Fruit flies can devastate entire harvests and have infested over 300 types of vegetables, fruits and nuts globally, causing financial ruin to countless farmers in the Arab world.

However, an ingenious system designed by Nisrine El Turky, a computer engineer and university professor, and Christina Chaccour, an electrical engineer, will tell farmers via text messages and mobile app of the best time to spray pesticides to halt the pests’ advance.

“Many Lebanese farmers weren’t able to export apples because the quality of their produce wasn’t good enough,” said El Turky, co-founder of IO Tree.

“So many I met were desperate to sell a crate of apples for $2 (SR7.50), which is nothing. I wanted to help the sector by better integrating technology.”

She began by investigating the difficulties that farmers faced, attending workshops and seminars, and visiting farms. She found the main problem was that farmers were spraying too much pesticide to try to kill fruit flies.

“I found a way that could reduce the use of pesticides and increase production.”

El Turky began working on the IO Tree concept in February 2018 and swiftly built a working prototype, which she showed to Chaccour, who promptly joined the company as a co-founder.

IO Tree’s technology is being tested on farms in Lebanon and the Netherlands. There are two prototype machines — one for indoor use and another for outdoor. The machines can be placed in an orchard, field or greenhouse.

“We need to ensure that the prototype functions in all conditions. Outdoors, there is sun, dust, rain and other weather factors that could disrupt its operation,” said El Turky, who still works up to 10 hours a week as a lecturer at Lebanon’s Notre Dame University.

Using machine learning and artificial intelligence, the machine’s sensors monitor indicators such as temperature and moisture, as well as studying plant stress.

The system can detect and identify pests, providing data on the likely scale of an imminent pest invasion and the best action the farmer should take to combat it. Information is conveyed to the farmer via IO Tree’s app.

“If you’re using pesticides, our app will tell you the best pesticide to use to tackle that problem, the quantity you need and when to spray.”

EL Turky said her technology had shown over 90 percent accuracy in identifying medflies.

“Machine learning means that every day the system becomes more accurate,” she said.

“We’re also working on identifying other pests, but medfly is our main target. Once medflies arrive at a farm, they will eat everything.”

IO Tree will enable farmers to use fewer pesticides, reducing environmental damage, while produce will be in better condition and can command a higher sales price.

“By using fewer pesticides, farmers will be better able to preserve biodiversity: Spraying kills a lot more insects than just pests,” she said. IO Tree has initially targeted all types of fruit trees, plus tomatoes and cucumbers, and the product will be launched commercially in September.

“We’re aiming at farmers directly,” said El Turky.

IO Tree’s services will be sold via subscription. After a farmer signs up for one year initially, the company will install its machines at the farm. The number of machines required per acre depends on crop type, crop yield, land topography and other factors.

The company’s initial target market is the Middle East, North Africa and Turkey, though it also plans to expand to Europe and eventually worldwide.

The product’s potential has helped IO Tree win a string of startup competitions. It was selected to represent Lebanon GSVC 2019 (Global Social Venture Competition) at the University of California, Berkeley.

IO Tree also joined Lebanon’s Agrytech accelerator, which provided $44,000 in funding, and schooled the fledgling entrepreneurs in how to create and manage a startup.
