NASA did the impossible 50 years ago -- putting a man on the moon -- and achieved a similar feat 50 years later ... putting on a spectacular Apollo 11 celebration for relatively pennies.

TMZ's got the receipts from the blowout celebration this week on the National Mall ... and according to federal procurement docs, NASA doled out only $1.4 mil for a series of special events ... that's like a small house in Burbank, maybe.

Now, get this -- at it's time, the Apollo 11 mission cost $25 billion -- a number experts say would land just south of $300 billion in today's dollars.

This week's events include hands-on exhibits, live performances, speeches from moon experts and a 363-foot projection of the Saturn V rocket on the Washington Monument. This showed how space exploration affects our daily lives and can inspire the next generation of explorers.

Federal procurement docs show NASA spent a little over $43,000 back in 2009 for the 40th anniversary of the moon landing ... a small celebration on Capitol Hill and a White House photo op with astronauts Buzz Aldrin, Michael Collins and Neil Armstrong alongside Barack Obama. That was like a backyard fireworks display compared to one at the Statue of Liberty for July 4th,  which is what's going down this weekend!!!

So, NASA saved it pennies ... presumably for a trip to Mars.

A$AP Rocky is getting royally screwed by Swedish authorities, and the battle lines have been drawn right here over race. So, we gotta ask ...

Manny Pacquiao says he wants to fight until he's 45 years old ... and when he retires, the boxing star tells TMZ Sports he will seriously consider buying an NBA franchise.

The 40-year-old superstar has made a FORTUNE during his boxing career -- and says he feels he's got AT LEAST another 5 years of fighting before hangin' 'em up for good.

"I feel like young, like late 20s," PacMan says ... explaining that he still loves the sport and all of the training that comes with it.

Pacquiao -- who's fighting undefeated star Keith Thurman on Saturday -- tells us he feels blessed by God ... and plans to use his gifts as long as his mind and body hold up.

Part of Manny's training regimen is playing basketball for 4 to 5 hours a day ... seriously.

In fact, Manny's so obsessed with the sport, he bought his own semi-pro basketball league back home in the Philippines called the Maharlika Pilipinas Basketball League (MPBL).

FYI, Forbes says Manny has made more than $500 MILLION during his boxing career -- including a $26 million haul over the past year.

So, we had to ask if he had NBA ambitions and the boxer gave us an emphatic "Yes!"

Full moons are notorious for bringing out everyone's wild side!!!

It's Moon Day and there is no better way to shed some light on this special holiday than by taking a look at these flashing stars.

Celebrities go through phases, just like the moon, so it makes sense that every now and again these famous faces share a little more than usual on social media.

Take a trip through our gallery of famous full moons to catch a glimpse of the famous fannys ... see if you can figure out the celebrity in the cheeky photo!!!

MacKenzie Ziegler is cashing in on some new songs, because we've learned the 15-year-old singer is raking in $175,000 for an advance on her music.

TMZ has obtained her minors contract that was filed in L.A. Superior Court. It says she inked a deal with Sony Music Entertainment. According to the deal, the advance is for a minimum of 12 new tracks.

According to the contract, Sony Music Entertainment agrees to pay MacKenzie the $175k advance, and she's guaranteed at least $9k for the first year, $12k for the second and $15k for the third contract year.

As for royalties, this is where MacKenzie can cash in even more, getting 20 percent in all music formats.

According to the deal, MacKenzie is also getting a $300,000 studio budget ... and another $20k toward an attorney.

It's another big payday for Maddie Ziegler's little sister ... MacKenzie pocketed $130k just last year after finishing as a runner-up on "Dancing with the Stars: Juniors."

Don't let these two almost identical images of superstar Jennifer Lopez steal all your shine! Make a name for yourself by seeing if you can uncover the sneaky switches made to this tricky pic!

Lopez was photographed earlier this week in New York City on her way to Madison Square Garden. The talented singer is currently in the middle of her 'It's My Party' summer tour.

Bring out those detective skills and take a really close look at this photo ... See if you can find the differences between these two super similar snaps!

New team, new pad -- L.A.'s newest superstar Anthony Davis has found a temporary home in his new territory ... renting an INSANE $14.1 million mansion in Bel-Air!!!

TMZ Sports has learned ... The Brow is resting his feet in a super private gated community in L.A. ... and the 12,000-square-foot house is a perfect for a big-time baller.

The 6-bedroom, 6-bathroom pad comes with a decked out gourmet kitchen, bar, personal gym, master bedroom with marble fireplace and walk-in closet, pool ... and of course, a basketball court!!!

We're told AD is renting the place for around $50k a month ... but the guy's in the middle of a 5-year, $127 million contract ... so it's a drop in the bucket for the All-Star.

FYI -- if Davis decides to crash at this spot during the season, it's only about a 35-minute drive to Staples Center!!! (But, you never know with L.A. traffic.)

AD's not gonna be far from his bestie, LeBron James, either ... he'll be about 15 min from his Brentwood neighborhood.

As A$AP Rocky rots in a Swedish jail for weeks without being charged with a crime, you gotta wonder how another rapper -- a white rapper -- accused of the same crime and more spent a relative nanosecond behind bars before being allowed to go on his merry way and leave the country.

You may recall a story TMZ broke a year ago in May, when G-Eazy was arrested in Stockholm after punching a security guard in a club and snorting coke using a $100 bill.

G-Eazy was arrested for assault, possession of drugs and use of narcotics. There was no video of the attack, yet prosecutors allowed him to strike a deal a day-and-a-half later ... he pled guilty to violent resistance, a crime of violence against an official and illegal drug possession. His sentence -- a $10k fine and probation. He was also ordered to pay the security guard $900.

That was it ... G-Eazy was allowed to leave the country, no muss, no fuss.

Now, compare that to A$AP. There's VIDEO of the assault -- actually 2 videos, the other being the alleged victim assaulting Rocky first -- yet prosecutors and the judge have kept him in jail for more than 2 weeks as they continue to "investigate" and decide if he'll be charged. As we reported, prosecutors mistakenly played their hand Friday and said he was going to get indicted.

A$AP faces 6 years in prison for his alleged assault. G-Eazy spend less than 2 days behind bars.

And, one more thing. Remember, back in 2015 Snoop Dogg was arrested in Sweden after being snatched out of his car because cops believed he was driving under the influence. He was forced to pee in a cup and was released after cops determined he was clean. Snoop, who was there for a concert, said it was a case of DWB and he would never return to the country.

So, what gives?

We now know how the Donald Trump/Kanye West phone call went down Friday ... Ye called the Prez.

Sources with first-hand knowledge of the convo tell TMZ, Kanye called Trump to express his frustration over the Swedish judge's decision to hold A$AP Rocky for another week while the prosecutor decides whether to charge him ... even though we know that decision has already been made.

Kanye told Trump he wanted to get personally involved in the fight to free A$AP, and the first step was calling the President. Kanye discussed the fact Trump could call the Prime Minister ... and we're told Trump was agreeable.

The call was quick. We're told Kanye has a direct line into the Oval Office.

Trump said earlier, he's gotten a lot of calls from people in the African-American community over the A$AP situation ... but then said African-Americans and everyone else are one.

Trump said Melania also brought the A$AP matter to him, although we know Kim Kardashian called Jared Kushner about A$AP, who then went to Trump and Trump then contacted Pompeo.

When the O.J. Simpson verdict came back not guilty, his team of lawyers celebrated the huge victory, but in no way did they disrespect the victims' families ... at least according to Shawn Holley.

The famed attorney -- who was part of Simpson's legal "Dream Team" -- tells TMZ ... Kim Goldman's recent claim that Johnnie Cochran leaned toward her while smiling and said "Gotcha" after the verdict was read, simply didn't happen.

Holley says she doesn't think Ron Goldman's sister is lying, but is mistaken or possibly misremembering the incident. She insists Cochran was always respectful of victims and their loved ones and insisted his colleagues be respectful too.

Holley says she was seated in between Kim and Johnnie ... so she knows what went down and what didn't. She also says the team was very aware any exuberance they showed could look bad, so they discussed being respectful before the verdict was read. Shawn adds, "there's no way in the world" Cochran made such a comment.

Goldman made the claim on Howard Stern's show earlier this week when he asked how sickened she was in the courtroom watching people celebrate the not guilty verdict. She also called the Dream Team's celebratory behavior "disgusting" and "beyond reproach."

Patriots fans ... look away -- Tom Brady just hurled himself off a cliff with his daughter in Costa Rica!!!

And, yeah ... it's just as cringe-worthy as it sounds!!!

TB12 hit up a lagoon on his annual pre-training camp vacay with his fam ... and for some reason, he decided to throw himself off the top of the rocks into the water with his daughter.

Things didn't exactly go swimmingly (sorry) ... when he counted off his daughter to jump in with him -- she hesitated ... and it created some seriously tense moments!!!

Fortunately for Brady, his daughter and the entire state of Massachusetts, everyone came up from the water just fine.

Of course, the G.O.A.T. is no stranger to these dangerous situations ... remember, it was back in 2012 when he threw himself off an even BIGGER cliff in Costa Rica.

President Trump says many people have reached out to him regarding the A$AP Rocky situation in Sweden ... and even the First Lady's concerned about getting him home.

POTUS addressed the media Friday and says he knows there's tremendous support for the rapper, and the U.S. government is working on helping him.

He says Melania also brought A$AP's plight to his attention and told him something needed to be done about it.

Melania says the ball's in motion with the State Department already, adding ... "we hope to get him home soon."

As we reported ... the judge has ordered A$AP to stay in jail, where he has already been for a couple weeks, while prosecutors continue their investigation. However, it seems they are set to indict him soon ... and they have argued he's a flight risk if he's allowed to leave jail.

A$AP's lawyer's calling this treatment unjust based on all the circumstances.

Also, we broke the story ... the treatment of the rapper is WAY different that what another white rapper, G-Eazy, went through last year despite a very similar set of circumstances.

Zion Williamson has still NOT signed a shoe deal -- despite being the most sought after NBA draft pick since LeBron James -- and our sources say it's all because of Puma.

Nike was believed to be the front-runner to sign Zion for months ... with legendary former Nike exec Sonny Vaccaro telling us he thinks Zion's deal could hit the 9-figure mark.

And, with Zion rocking Nikes in college, in pre-draft workouts and in some NBA Summer league games ... it seemed like it was just a matter of time before Zion signed with the Swoosh.

But, we're told Puma -- which has made a serious push in the basketball shoe space in recent years -- has come out of nowhere to become a major contender to sign the NBA's #1 overall pick.

Puma already has rising stars Marvin Bagley III and DeAndre Ayton on its roster -- the first 2 picks from the 2018 NBA Draft.

And, get this ... Zion rocked a pair of Puma RS-0 "Video Game" kicks during a Summer league game earlier this month, and our sources tell us that's no coincidence.

We're told Nike is aware of the competition and is making a hard push to get a deal done with Williamson first. As one source puts it, "He's the #1 priority."

Remember, Zion did have one bad experience with Nike in college ... when his Nike PG 2.5s blew out during the opening seconds of the Duke vs. North Carolina game.

Fun Fact: The shoes were never seen in public again after that incident ... and Ken Goldin from Goldin Auction told us he thinks the kicks could be the most valuable collegiate sneakers of all time ... worth more than $250,000 if they ever hit the auction block!!!
