Pete Davidson won't be going to space -- at least not during Blue Origin's next trip -- he's dropped out of the flight after it's launch date was pushed back.

Jeff Bezos' Blue Origin made the announcement late Thursday, saying, "Blue Origin's 20th flight of New Shepard has shifted to Tuesday, March 29. Pete Davidson is no longer able to join the NS-20 crew on this mission. We will announce the sixth crew member in the coming days."

The announcement is surprising, considering the launch date was supposed to be less than a week away on March 23.

It's currently unclear why Pete will be unable to make the trip, but as we reported -- he's been working on various projects, including James DeMonaco's "The Home" in which Pete was spotted covered in blood for a scene. So, it's possible one of them got in the way.

As for the remaining passengers who were scheduled to go up with Pete -- there's Party America CEO Marty Allen, hubby and wife duo Sharon and Marc Hagle, entrepreneur Jim Kitchen and Commercial Space Technologies Prez Dr. George Nield.

We got pics of Pete and Kim grabbing In-N-Out Thursday night in L.A. so it appears if there was even such a thing as a space diet, it's clearly out the window -- and for good reason.

Elon Musk has vowed to become a real-life action hero, saving the world -- or at least part of it -- by thwarting any attempt by the Russian Government to send the International Space Station hurtling toward earth.

Musk is reacting to a Russian space official who menacingly suggested the ISS could lose its trajectory and careen toward the U.S. or Europe if the Russians sabotage the craft. The official suggested sanctions could trigger the move. Russia controls the engines on the ISS, and it can direct the trajectory accordingly.

Musk's Twitter response ... a SpaceX logo.

Someone on Twitter inquired if E.M. was suggesting SpaceX would prevent the ISS from plummeting to earth. His response -- "Yes."

Musk acknowledged another tweet with the ISS, but one thing was missing -- any evidence of Russia. Instead, the SpaceX Dragon spacecraft was front and center.  Elon responded, "Good thread."

The ISS could do lots of damage for sure ... it weighs in at 500 tons.

As for how serious the threat, the Russian official said, "The ISS does not fly over Russia, therefore all the risks are yours. Are you ready for them?"

NASA says nothing's changing with respect to ISS operations. What's unclear ... can Russia do what it's threatening?

Don't count Musk out ... NASA has increasingly relied on SpaceX for space exploration.

There was something strange appearing in the sky over Tennessee ... and it prompted an eyewitness' super funny reaction to the prospect of UFOs.

Check out this wild, hilarious video obtained by TMZ, which appears to show multiple lights in different formations high above Memphis.

We're told this was shot a couple days ago, on Dec. 27, in the evening ... and you can see the lights forming a line and a triangle.

The eyewitness who shot the video is beside herself ... "Y'all, what is that y'all?!? Y'all what the f*** is that?!? Oh my God, y'all!!!"

It's unclear what we're seeing here, but they don't appear to be planes ... and it's the latest in a string of unidentified objects being spotted in our skies.

Earlier this month, we obtained video of a swarm of lights darting around the airspace above Chino Hills, CA ... looking like giants orbs in the heavens.

And, there was also the pilot who recorded what appeared to be a fleet of UFOs over the Pacific.

The Dept. of Defense is launching a new UFO task force ... and it would be hilarious if this Memphis eyewitness narrated all their evidence.

Harry Reid, the former Senate majority leader and the driving force behind the UFO movement in Congress over the years, is dead.

The famed Democratic Senator from Nevada died Tuesday in Henderson, NV ... according to Nevada Gov. Steve Sisolak and current Senate majority leader Chuck Schumer.

The cause of death is unclear ... but Harry was diagnosed with pancreatic cancer back in 2018 and received intensive treatments.

Harry was a big deal in Nevada and Washington D.C. ... rising the political ranks after being born to a poor family in a tiny mining town in rural Nevada. He grew up as a boxer before getting into politics.

Reid served 34 years in Congress, starting as a Representative in 1983 before being elected to the Senate in 1986 and later becoming the chamber's Democratic leader following the 2004 election.

Schumer, who succeeded Reid as the Senate Democratic leader, is remembering Harry as "one of the most amazing individuals" and "tough-as-nails strong."

Being from Nevada, the home of the infamous Area 51, Harry became increasingly interested in UFOs ... and in 2007 he secured funding for a Pentagon program that investigated reports of UFOs and other related phenomena.

The UFO program, formerly known as the Advanced Aerospace Threat Identification Program, no longer exists but the government is still studying UFOs ... and things wouldn't be where they were today without Harry.

Reid was 82.

Neil deGrasse Tyson says the new NASA telescope observing the origins of the early universe isn't a shot across the bow at religion ... but being flexible is the key.

The famed astrophysicist joined us on "TMZ Live" and we asked if the research being done using the $10 billion Webb space telescope could challenge the foundations of religion.

Neil says the telescope, which launched into space on Christmas, will be used to fill in some gaps with the big bang theory ... but he's not buying the argument that such research will clash with generations of folks who believe God created the universe in 6 days.

The way Neil sees it ... religious folks are becoming more flexible and looking at things in a more spiritual sense ... so new discoveries won't cut to the core of belief systems.

Mark Rylance's turn as a deranged tech CEO in 'Don't Look Up' is a clear dig at our country's leading billionaire visionaries -- but the question ... who's it actually aimed at???

You've probably heard about this new Netflix flick -- but what you may not have known ... Rylance portrayal as chief of a revolutionary company is getting compared to guys like Elon Musk, Jeff Bezos, Mark Zuckerberg, Tim Cook and others pushing the information envelope.

One thing the internet can't seem to agree on ... which of these billionaires serves as the true inspiration behind Rylance's Peter Isherwell, who ends up contributing to everyone on Earth (save a select few) getting killed by an incoming comet. Sorry, spoiler alert!

For those who've seen it, you know Isherwell runs a company called BASH, which seems to be a spinoff of Apple -- a la Cook/Jobs -- but it's way more advanced, in that it reads your every thought and mood, and predicts how you'll die ... all based on data it collects on its users. Isherwell, funny enough, also runs a space unit of some sort ... similar to Musk.

In the end, Isherwell's plan to blow up the incoming comet and collect the precious minerals found within it completely backfires ... having led Meryl Streep (the President) and the rest of the world's citizens astray. He high-tails it off Earth, before it blows up, in his own rocket, and attempts to colonize a new planet in the distant galaxy (which also hilariously backfires).

The point is ... the dude seems to be an amalgam of all these guys in one -- although most people appear to think he's most like Time's Person of the Year for 2021.

It sounds like Rylance himself sees a little Elon in his character as well ... although he's quick to point out Isherwell isn't necessarily a dead ringer for any one of the tech-y billionaires, despite him certainly being a farcical take on just about all of them.

As he explains, Isherwell's actions are premised on the idea that any of our world's problems can be solved with technology -- a testament to our times and where we're headed.

There's gonna be less space in space, because the newest clutter is the most powerful telescope ever hurled into the heavens, and it promises a new, never-before-seen look that could alter the way earthlings live.

We're talkin' The James Webb Space Telescope, which lifted off early Xmas morning from Europe's Spaceport in French Guiana.

NASA described the launch this way ...  "At 7:20am ET (12:20 UTC), the beginning of a new, exciting decade of science climbed to the sky. Webb’s mission to #UnfoldTheUniverse will change our understanding of space as we know it."

That may not be an overstatement ... the telescope is the most powerful and most complex ... a space observatory that will study exoplanets -- those are planets outside our solar system.

Thing is ... scientists think some of the exoplanets could be habitable, and that means 1) is there existing life on any of them? And 2) could we live there either by choice or necessity?

There have been years of delay in launching the scope for various reasons. As for specs -- its mirror can extend more than 21 feet, which gives it the ability to capture more light from the objects it's photographing ... and that will enhance the details scientists will study.

The mirror has 18 hexagonal, gold-coated segments ... fancy!

Bottom line ... scientists should be able to see things, including planets, they've never seen before.

William Shatner seems to have a safer trip flying in a humongous spaceship than he does driving a car on planet Earth -- evidenced in the fact he got into a wreck cruising the streets of L.A.

Captain Kirk was involved in an accident Tuesday in Studio City, which actually looked pretty bad ... from the damage done, anyway. WS was driving his black Mercedes SUV, while the other driver was in an Acura sedan.

Unclear exactly how the two vehicles ended up as crumpled as they were -- but as you can see ... the woman's front end is pretty smashed up, with her left wheel at a weird angle.

Luckily, neither Bill nor the woman appeared to be injured ... and the 90-year-old actor was quickly on his feet and over with the woman making sure she was okay, while he made some calls and kicked debris off the side of the road.

Cops were called to the scene, made sure both drivers swapped info ... and thankfully no one was taken to the hospital.

A SpaceX rocket blasted off Tuesday night for a mission of self-destruction ... and its end game is to save planet earth!

NASA commissioned Elon Musk's rocket company to hurl a Falcon 9 rocket into a nearly year-long journey which will end with the spacecraft bashing into a faraway asteroid.

Scientists want to see if the impact could actually change the asteroid's trajectory ... something that could be lifesaving if it were headed toward mother earth.

The spacecraft -- dubbed DART, short for Double Asteroid Redirection Test -- left earthly terra firma at Vandenberg Space Force Base in Cali ... and the whole thing is kinda like a ripoff of "Armageddon."

DART is supposed to violently connect with Dimorphos -- an asteroid that measures 525 feet across -- at a speed of 15,000 MPH.

Scientists say the impact will not destroy the asteroid ... but the goal is to change its orbit.

It's complicated, but if the asteroid moves for a minimum of 73 seconds, the mission is considered a raging success!

SpaceX can check one more accomplishment off its list -- successfully completing an ISS mission, now that its astronauts have touched down on Earth in grand fashion.

Elon Musk's Dragon capsule safely landed Monday evening, parachuting into the Gulf of Mexico without a hitch ... but not before it was seen streaking across the night sky, especially in New Orleans -- where it looked like a shooting star, or even an asteroid.

This might've freaked some folks out ... but rest assured, it was just the Endeavor crew torpedoing back into our atmosphere after being up in orbit for more than 6 months. Indeed, this was the crew SpaceX/NASA shot into space back in April ... 'memba that?!?

The astronauts who went up were Shane Kimbrough, Megan McArthur, Akihiko Hoshide and Thomas Pesquet ... and they linked up with the International Space Station, where they've been doing research and fieldwork for this entire time.

Now that they're back, and the mission's apparently a success, Elon can proudly say he's helped get the U.S. back into space after a multi-year hiatus. The last time we were up there for an extended period of time was way back in the early 2010s, but that program was paused by NASA -- that is, until SpaceX jumpstarted things with this launch.

Pretty sweet feat ... and it definitely puts Elon higher on the billionaire's space race totem pole, alongside guys like Jeff Bezos and Richard Branson -- who haven't gone quite as far up as SpaceX rockets/capsules have.

Oh, and BTW -- the team here had a little bathroom trouble on the way down ... NASA advised them not to use the onboard toilet -- due to malfunctions that made it inoperable -- so they had to improvise for their bodily functions. Yep, you guessed it ... diapers for everyone!!!

NBD, they handled the crappy situation with professionalism and humor.

The all-civilian space mission that Elon Musk and co. sent up into orbit is officially a success -- because the 4-man crew is back home ... and TMZ is streaming the crew member pickup live.

The team, known as Inspiration4, re-entered our planet's atmosphere Saturday in a Dragon capsule -- getting burnt up badly as it barrels down to Earth, to be expected in these types of voyages. Luckily, there was some major parachuting going on to slow this puppy down ... and the spacecraft safely landed in the Atlantic, off the coast of Florida.

Before they touched down ... it looks like the crew was watching some appropriate Mel Brooks content -- during the livestream, you could see one of the normie astronauts streaming "Spaceballs" on a small monitor in front of 'em. Good stuff!

Anyway, when they finally did make contact -- it made for a dramatic splash. Not too dramatic though ... SpaceX had rescue ships at the ready to pick up the passengers and take them back to shore -- which they're in the middle of doing now. It went about as as smoothly as one could hope for.

Remember, billionaire Jared Isaacman led the mission ... alongside Chris Sembroski, Dr. Sian Proctor and Hayley Arceneaux, all of whom have been zipping around the planet for a few days straight -- confined to the seats in the small space of their capsule.

Yes, that means they had to use the same toilet ... and refrain from showers. The fact they pulled it off opens the door for space tourism in the near future -- a whole new chapter many of us never thought possible.

These four individuals had to go through rigorous training to be in shape to be blasted off toward the stars -- but if you can get through that (and pay the high price tag) ... it's definitely something you can check off your bucket list in your lifetime.

Elon Musk's space company just made history ... the first ever, all-civilian spaceflight is way up above our planet ... and they blasted off without any astronauts.

Billionaire Jared Isaacman, a pilot himself, is leading the mission dubbed Inspiration4 ... and it looks like he's already having a blast up there in space with the rest of his lucky space tourists.

Chris Sembroski, Dr. Sian Proctor and Hayley Arceneaux took off with Jared in a SpaceX Dragon capsule Wednesday night ... blasting into space using a Falcon 9 rocket, which launched from NASA's Kennedy Space Center in Florida.

As you can see ... the space tourists were clapping and celebrating as they took off into space, breaking the speed of sound on the way up, while those in mission control back home were hyped too.

Now that they're in orbit, Jared and co. will be in space for the next 3 days, zipping around Earth about once every 90 minutes and enjoying the views.

As we first told you ... Jared told us back in February he was most looking forward to overriding the automatic pilot and taking Dragon for a spin up in space.

BTW ... the civilian crew will be sleeping in the same reclining seats you saw them in on the launch ... and they've got to share a toilet and forego showers.

Elon Musk's a billionaire with modest taste ... just check out his tiny digs in Texas.

The Tesla chief is living it up in this pre-fabricated casita near his SpaceX headquarters in Boca Chica, Texas. The entire thing's a whopping 375 square feet ... with 1 bedroom, 1 bathroom as well as a living room and kitchen.

Yup, there's a dishwasher and even a washing machine.

Las Vegas-based Boxabl is selling the houses for a cool $49,500. The company tried its best to be subtle about scoring Elon as a customer -- it announced back in November it installed one of its pre-fab cribs in Boca Chica for a "top secret customer."

The company's founder, Galiano Tiramani, had said it was "pretty exciting to have these guys as our initial customer." He didn't confirm the house was built for Elon himself but, just a couple of months ago, Elon confirmed in a tweet he was, in fact, living in the tiny home and renting it from SpaceX.

It should come as no surprise that one of the world's richest men can pull strings for this tiny house, which reportedly has a 47,000-person waitlist.

NASA says it needs some guinea pigs to test out what life on Mars would be like for a year -- right here at home -- and they're asking for regular Earthlings to help out.

The space agency put out a want ad this week, asking for "healthy, motivated" U.S. citizens and/or permanent residents to sign up and volunteer for a year-long simulated experience ... which will apparently put 4 lucky participants together in a 3D printed bunker-like environment.

NASA has an idea of what the fake 1,700 square-foot Mars fort (of sorts) will look like ... something like what you see above.

Anyway, sounds like they're going to be doing a few of these "missions" -- with the first set to begin in Fall 2022 and take place at NASA’s Johnson Space Center, where they'll recreate Mars conditions and put these folks through different tests ... for, like, research and whatnot.

Some of the things one might expect to be dealing with while there ... handling resource limitations, equipment failure and other environmental stressors. There's also the strong possibility NASA will make you go through simulated spacewalks, scientific research, use of virtual reality and robotic controls and "exchanging communications" ... as they put it. 👀

There might be some pay, it seems ... but the amount isn't specified in NASA's press release. But, still, it's kinda cool ... right??? BTW, we know we said ordinary people are wanted -- but that's isn't entirely true ... NASA is seeking the best and the brightest for these simulations.

It's been nearly two decades since military aviator Chad Underwood filmed the "Tic Tac" UFO sighting ... but for the first time EVER he's breaking his silence in front of a camera.

Underwood's highly-anticipated interview will go down Wednesday at noon PT on Jeremy Corbell's YouTube show "Extraordinary Beliefs." The video -- filmed in November 2004 off the coast of San Diego -- was captured off the left wing of Chad's F/A-18 Super Hornet.

The sighting and filming is considered one of the most famous and important videos in UFO history ... largely because a military officer filmed it during an official flight-training exercise. The video was also famously declassified by the Pentagon in 2017.

The video shows an object go from 80,000 feet to sea level in less than a second and a half ... the forces of which human engineering and, for that matter, humans cannot withstand. The object had no wings, no obvious propulsion system and no exhaust.

Underwood, at the time a Navy Weapon Systems Officer on the elite squadron dubbed Black Aces, will offer insight into his encounter with the UFO. He'll also clarify many details the public has been wanting to hear ... as in, the footage he shot is only the beginning.

The half-hour interview will cover a myriad of subjects ... like the origin of the name "Tic Tac" UFO. He'll also talk about behavioral sightings and if his kids ask him about alien encounters.

As we previously reported ... the Pentagon released a 9-page report last month in what was supposed to offer insight on a rash of recent UAP (unidentified aerial phenomena) sightings.

Instead, the report turned out to be a nothing burger ... 'cause the Office of the Director of National Intelligence only noted that 143 of the 144 flying objects spotted since 2004 remain unexplained.

There's a notable, near-ish-collision on Earth -- or at least one that's looming -- and the object that may be about to crash is traveling at 18,000 MPH!!!

NASA has sounded an alarm that a giant asteroid is about to pass Earth. It's somewhere between 318 and 720 feet in length ... about the size of the Taj Mahal and the Great Pyramid of Giza.

The thing's even got a name -- 2008 G020.

Well, when we say near-collision, it's all relative. It's supposed to come as close as 2.8 million miles to our planet. In NASA-ese ... it's labeled an Apolo, which is a "near-Earth" designation.

To give you more context ... the Moon is 238,855 miles from Earth, while Mars is 236.5 million miles away. So, somewhere in the middle.

This won't be our closest encounter with G020. In 1901 it got 1 million miles from Earth.
