American flags on the moon are still standing, but they’re now blank

Apollo mission remnants can be seen by the Lunar Reconnaissance Orbiter

When astronauts first touched down on the moon in 1969 as part of NASA's Apollo 11 mission — and for every Apollo mission that followed — they left behind evidence that they'd been there, some intentional and some necessary. The most iconic of these were six American flags, all of which were thought to have been destroyed by the harsh conditions on the lunar service or at least knocked over my now. As it turns out, all but one are still standing.

Photographs taken by NASA's Lunar Reconnaissance Orbiter (LRO) satellite show that five of the flags are right where we left them. The first one, by Apollo 11's Neil Armstrong and Buzz Aldrin, was blown down by the lift-off thrust from their lunar lander as it left the moon's surface to reunite with the orbiting command module. The LRO images also show objects such as the lunar rovers used by some Apollo missions, and even the tire tracks they left behind.

One of the most intriguing aspects of these photos is the fact that the remaining U.S. flags have all turned white. This happened due to bleaching by sunlight, which hits the flags for as long as 14 days at a time without any sort of atmosphere to filter its rays. Manufactured from nylon without any thought as to retaining their looks over the decades of lunar exposure — they weren't even expected to be standing for long — the flags cost only $5.50 in the 1960s. We're guessing that the flags eventually carried to Mars by Earth's astronauts will probably be made to last longer — and cost a pretty penny more.

      A dozen bodies -- including seven that were headless and mutilated -- were discovered over the weekend in western Mexico's seaside resort of Manzanillo, apparent victims of the country's epidemic of drug violence, local officials said. It was a shocking turn of events for an area popular with American and other foreign tourists, which until now had largely been spared from the bloody drug wars wracking other parts of Mexico. Seven bodies were found early Saturday in an abandoned taxi on the road from Manzanillo to the town of Cihuatlan.

    • China to prosecute former Tianjin mayor for suspected graft

      China will prosecute the former mayor of the northern city of Tianjin for suspected graft, the state prosecutor said on Sunday, taking a step that will almost certainly result in his conviction. Dozens of senior people have been investigated or jailed since President Xi Jinping assumed power four years ago, vowing to root out corruption, warning, like others before, that the problem threatens the Communist Party's grip on power. The party announced in September the investigation into Huang Xingguo, who had been mayor of the important port city - about an hour from Beijing - since 2008.

    • Twitter roasts Trump aide for calling lies 'alternative facts'

      In the world of fake news, now we also have "alternative facts."  On Saturday, President Donald Trump's first full day in office, his press secretary Sean Spicer held a press conference in which he falsely claimed that the previous day's crowd was the "largest audience to ever witness an inauguration, period." SEE ALSO: Inauguration crowds are looking puny compared to Women's March crowds Spicer's false remarks instantly became a new meme and sent the internet into a fury. On Sunday, Kellyanne Conway, counselor to President Trump, appeared on NBC's Meet The Press , where Chuck Todd grilled the Trump administration for spreading falsehoods on their first full day in office. In response, Conway called the falsehoods "alternative facts." "Alternative facts are not facts. They are falsehoods," Chuck Todd tells Pres. Trump's counselor Kellyanne Conway this morning. WATCH: pic.twitter.com/Ao005dQ13r — Meet the Press (@MeetThePress) January 22, 2017 Yes. Alternative facts.

I care about you. I have divested from my businesses.I have the biggest crowds.#alternativefacts — Unpresidented (@UnpresidentedAF) January 22, 2017 In addition to Spicer complaining about the media's coverage of crowd size, Trump also complained during a briefing at the CIA headquarters on Saturday. "We had a massive field of people. You saw that. Packed," said Trump. "I get up this morning, I turn on one of the networks, they show an empty field. I said, wait a minute, I made a speech. I looked out, it looked like a million, a million and a half people. They showed a field where there were practically nobody standing there." There is no official estimate of the crowd size on inauguration day, but there are some simple facts to prove it wasn't "the largest audience to ever witness an inauguration." According to the Washington Post , the D.C. Metro's ridership was "lower than that of an average weekday." About 570,557 people rode the Metro on Friday vs 1.1 million who rode it in 2009 during Obama's inauguration. According to Nielson, 31 million viewers watched the inauguration on TV, which is lower than both Obama and Ronald Reagan's first inaugurations. Spicer also claimed that magnetometers were used on the National Mall for Trump's inauguration and prevented "hundreds of thousands of people from being able to access the mall as quickly as they had in years past." A Secret Service spokesperson told CNN that magnetometers were not used during the inauguration. A USSS spokesperson tells us no magnetometers were used on the National Mall for Trump's inauguration. — Jim Acosta (@Acosta) January 22, 2017 The floor coverings Spicer mentioned, that was also a lie.

    • Inauguration crowds are looking puny compared to Women's March crowds

      Sorry, Trump, but these Women's March crowds are YUGE. Ladies from around the world got in formation to take part in the Women's March on Washington following Trump's inauguration, and the crowds are downright bigly. With attendance projections for the D.C. March now at over 500,000, many can't help but compare today's attendance to Friday's underwhelming inauguration numbers. SEE ALSO: Who pulled the bigger crowd: Trump or Obama? While hundreds of thousands did show up to watch Trump be sworn in as the 45th President of the United States on Friday, visible empty bleachers and photos of Obama's packed 2009 inauguration ceremony,which had an estimated turnout of around 1.8 million, proved Trump's gathering was far from record setting. The March reportedly led to 1,000 more busses being booked than on Trump's big day, and photographs and video from today's events show D.C. bombarded with an overwhelming number of attendees. Though official inauguration numbers are unknown, the gorgeous sea of pink Pussyhats assembling at today's March certainly appeared to trump the president's crowds.
