Given enough time, humans will eventually live on Mars, but as you can probably imagine, a few things need to be worked out before we get there.
One of the biggest supporters of colonizing our neighboring red planet is SpaceX CEO Elon Musk, who has been a leader in pushing the boundaries of human space exploration. Musk has recently taken to his Twitter page to reveal one of the most critical things that are needed for humans to live on Mars, and it may not be something you would have guessed.
According to Musk, "Public support for life on Mars is critical to making it happen". Transporting humans to Mars will undoubtedly be the biggest challenge the human race has faced to date. To make it happen, Musk believes there needs to be "public support for life on Mars", meaning that everyone needs to get behind the overwhelmingly large project. Maybe once humans have begun colonizing Mars, we could see DOGE coin become the backing of the financial system? Wouldn't that be the day....
The whole world is waiting on the edge of their seat to see what Tesla and SpaceX founder Elon Musk will do and say when he hosts Saturday Night Live on the weekend. But what we do know, for a fact is that on May 8 when Musk hosts SNL it will be exactly 6942 days since SpaceX was founded. The fu...
Everyday Astronaut replied to Musk's tweet sharing the image that SNL uploaded of him at Studio 8H, saying that he "couldn't help but notice" that Elon Musk will be hosting 6942 days after founding SpaceX. He added that the "simulation is officially getting weirder" and he's right about both of those things.
Why does this matter? Elon Musk has made multiple references to 420 (the number used to refer to weed, or cannabis) and 69 well, because, for super obvious reasons. Back in December 2019, Tesla stock reached $420 and Elon Musk tweeted out:
SpaceX now has more than 1,300 Starlink satellites orbiting Earth, and on Tuesday, SpaceX revealed that more than 500,000 people have already placed their $99 deposit for the internet service.
Elon Musk has replied to a recent article post by Michael Sheetz, the space reporter for CNBC, who was writing about SpaceX already receiving more than 500,000 orders for the Starlink internet service. It's noted in the CNBC article that the deposits are fully refundable if the service isn't provided. Musk replied to the article on Twitter to discuss some of the limitations of the Starlink internet service, saying, "Only limitation is high density of users in urban areas".
Additionally, Musk also said that "Most likely, all of the initial 500k will receive service. More of a challenge when we get into the several million user range." At first, the Starlink satellite internet service will only be available to people in North America, but eventually, SpaceX plans to roll the service out to as many countries as it possibly can. At the moment, SpaceX has permission to launch up to 12,000 Starlink satellites, which shows just how much more work SpaceX has to bring this competitive internet service to life.
Most UFO sighting claims can be explained by something boring or obvious, and to onlookers of the Washington skies on Tuesday night, these "sightings" are no different.
News outlets have reported that many people took to social media to ask what they were seeing in the skies above western Washington late Tues night. Many residents began to record bright light in the sky, with some onlookers claiming that what they were witnessing was a Unidentified Flying Object (UFO). Unfortunately, as with most UFO sightings, there is a very simple explanation that certainly throws a wet blanket on the whole UFO theory.
SpaceX just launched its most recent Starlink satellite mission yesterday, and what Washington residents are actually looking at is tiny satellites all slowly spreading out to form a line. Once in position, SpaceX continues to spread them out so they can synchronize and link up with the larger Starlink grid. It's understandable that people who aren't aware of how Starlink works would think what they are seeing in the eyes is some extraterrestrial magic, but unfortunately, that isn't the case. It's just SpaceX working it's magic.
Stars have a very violent ending to their lives, they erupt in an explosion that is called a supernova, which is them basically collapsing on themselves.
Astronomers have a good idea of how and why stars go supernova at the end of their lifespans, especially for yellow stars. Most yellow stars have a protective layer of hydrogen that encases the extremely hot center which when looked upon would appear blue to our eyes. When a yellow star begins to go supernova all of the hydrogen layer that is encasing its insides is expelled outwards in a violent burst, but not if you are 2019yvr.
2019vyr didn't show any hydrogen around it in the years before it went supernova, which has puzzled scientists as this doesn't fit current scientific models. Charles Kilpatrick, lead author of the study said, "We haven't seen this scenario before. If a star explodes without hydrogen, it should be extremely blue - really, really hot. It's almost impossible for a star to be this cool without having hydrogen in its outer layer. We looked at every single stellar model that could explain a star like this, and every single model requires that the star had hydrogen, which, from its supernova, we know it did not. It stretches what's physically possible."
Researchers here on Earth are very excited to get their hands-on the new Mars specimens that are being collected by the Perseverance rover.
According to NASA's Director of Planetary Science, Lori Classe, the samples that are collected from Mars should "provide new insights for decades to come as we study them with sophisticated laboratory equipment that cannot be brought to Mars." While this optimism to bring back samples from Mars to Earth is shared by many scientists, a group of researchers are concerned about potentially contaminating Earth's biosphere.
A team of scientists at the International Committee of the Red Cross (ICAMSR) has issued a warning against returning any model from Mars back to Earth. Instead, the team suggested that the samples should be taken to the Moon, where any pathogens can be identified without endangering Earth. Carl Sagan, a renowned and famous astronomer, wrote back in 1973, "Mars has a vast potential biological environment, and there are pathogens and organisms on Mars that can cause enormous biological damage if they are carried into the Earth's environment. "A Mars Plague".
The rocket designed by Elon Musk's SpaceX that is poised to transport humans from Earth to Mars has completed its first test flight.
SpaceX on Wednesday has successfully launched its first test flight of its Mars-bound rocketship named Starship. The four previous tests of the large rocket have ended in aggressive explosions either before, during, or after the launch. Starship took to the skies and soared for more than 6 miles above the Gulf of Mexico before descending horizontally and then flipping vertically for the touchdown.
Launch commentator John Insprucker announced, "Starbase Flight Control has confirmed, as you can see on the live video, we are down. The Starship has landed!" Once Starship landed, a small fire at the base of the rocket persisted. This fire was quickly extinguished by the landing pad's water cannons. Elon Musk posted to his Twitter saying that the Starship flight and landing was "nominal". For more information on this story, check out this link here.
The US Space Command is currently tracking the out-of-control rocket that China recently launched.
The rocket is roughly 100 feet in length and weighs 21 tonnes. When the rocket falls back to Earth, it will be one of the biggest space debris ever to crash back down to Earth. The rocket is currently traveling at a ridiculous speed of 16,000 mph and is rotating around the Earth once every 90 minutes. Due to the multitude of variables, officials have had a hard time determining where the rocket will land.
According to the Aerospace Corp, the trajectory of the rocket indicates that it will land somewhere in the Pacific near the Equator after passing over eastern US cities. However, this isn't officially confirmed. Originally, the orbit of the rocket indicated it could land anywhere between New Zealand and New York. Additionally, the US defense department says that the rocket will likely land on Saturday this week, but the exact location "cannot be pinpointed until within hours of its re-entry".
Star Wars fans have been waiting a long time to get their hands-on a real-life lightsaber, and they soon will be able to, but expectations of what it will actually be like may need to be dialed back a bit.
In the above video that has been posted to the official Disney Parks YouTube Channel, we get a very quick 13-second glimpse at the new lightsaber. The Verge states that the lightsaber is "working", and that it's a part of the Star Wars: Galactic Starcruiser luxury hotel that will be opening at Walt Disney World Resort in 2022. Engadget reports that patents for the lightsaber indicate that it works by a motor that extends a blade of LED-illuminated plastic.
At the moment, it isn't confirmed if you will be able to purchase the lightsaber, but it certainly would be surprising if Disney doesn't sell it, because I'm sure there are many Star Wars fans out there that would love to own one. If the lightsaber is high-quality, the price of the weapon could be anywhere in the $200 range as the already existing Galaxy Edge is priced at $200.

Everyone will soon have the opportunity to go for a quick trip up to space, and one of the companies that is providing the service is Jeff Bezos' Blue Origin.
Blue Origin is led by Amazon CEO Jeff Bezos, and according to a recent announcement on the companies Twitter page, the first tickets aboard the New Shepard rocket will be going live very soon. Blue Origin has said it will be revealing details on how you can purchase a seat on May 5, and if you expected it to very expensive, you assumed correctly.
Going to space is by no way a cheap process. When you factor in every cost, you can find the dollar value of each pound of weight. Blue Origin hasn't officially revealed any prices for a ticket aboard the New Shepard but has said that it will be competitive in the market. Virgin Galactic, another company that is yet to begin space tourism, has priced its tickets at $250,000. So, we can assume that Blue Origin will be anywhere in the $150,000 - $200,000 range, perhaps even lower.
