SpaceX sets new record with rocket recycling programme – Proactive Investors USA & Canada

Published

on


SpaceX Inc, the rocket-business owned by Tesla Inc (NASDAQ:TSLA) CEO Elon Musk, passed another record yesterday when it blasted the same power base into orbit for the sixth time.

The Falcon 9 flight was SpaceX’s 100th mission and mostly carried Starlink satellites, the company’s own broadband platform.

The booster (1049) part of the rocket landed again on a drone ship around nine minutes after take-off, making another record for safe landings (six) back on Earth.

SpaceX’s last three payloads using this particular unit have been Starlink satellites and the company is expected to start offering a limited internet service possibly early next year.

Another SpaceX launch is planned for later this month when an Argentinian satellite is to be sent into orbit.

Jupiter's newest Flyby offered the most amazing views. – haveeruonline

Jupiter's newest Flyby offered the most amazing views.

Jupiter.

The largest planet in the solar system-twice as much as all other planets combined. This enormous world was formed from the same clouds of dust and gas that became our sun and the rest of the planet.

But Jupiter Was the eldest son Of our planetary family. The massive gravitational field of the first planet, Jupiter, most likely formed the rest of the entire solar system.

Jupiter may or may not have played a role in the position where all planets orbit around the sun. This is because the asteroid belt is a vast area that can be occupied by other planets. Jupiter’s gravity.

Gas giants such as Jupiter also throw entire planets out of the solar system or head towards stars.

Millions of years later, the formation of Saturn probably helped Jupiter escape this fate.

Jupiter can also act as a “comet catcher”. Otherwise, comets and asteroids that could fall into the inner solar system and attack a rocky world like Earth would instead be captured by Jupiter’s gravitational field and ultimately Jump into the clouds of Jupiter.

But at different times in Earth’s history, Jupiter May have had the opposite effect, Throwing an asteroid in our direction-it’s generally a bad thing, but water-rich rocks that lead to the blue planet we know today may have entered Earth.

Jupiter is a window into our solar system’s past. The past, literally shrouded under Jupiter’s clouds, is the reason why Juno, the spacecraft currently orbiting Jupiter, was so named. Mythical Jupiter’s wife Juno was able to peek into the cloud cloak that Jupiter uses to conceal himself and his injustice.

But in this case we are looking at our own history through the clouds of Jupiter. Juno entered Jupiter’s orbit on July 5, 2016 after traveling for almost five years to reach the gas giant.

Falling into Jupiter’s gravitational well, Juno reached a speed of 210,000 km/h. This is one of the fastest speed records ever set by any human-made object.

Juno is on a very eccentric 53-day orbit. During the Perijove or nearest orbital approach, Juno scans Jupiter at an altitude of 4,200 km, then sweeps 8.1 million km outward. Juno’s orbit is designed to navigate the weak areas of Jupiter’s incredibly powerful magnetic field.

Second power over the sun itself, Jupiter’s magnetic field accelerates high-energy particles emanating from the Sun, creating a powerful band of radiation surrounding the planet.

In addition to agile navigation, Juno’s electronics are enhanced against radiation through a “radiation vault”, a 1 cm thick titanium shell that houses sensitive scientific equipment.

One of the devices that dazzle us all on Earth is JunoCam. RGB color cameras visually image Jupiter’s clouds as the probe buzzes each orbit in 2 hours, consuming as little Jupiter’s radiation time as possible.

Most recently, Juno completed Perijove 29, some photos published by “Software Engineer, Planetary and Climate Data Wrangler, Scientific Data Visualization Artist”. Kevin Gil.

Kevin is absolutely amazing Flickr page He publishes images processed by Juno as well as other missions like Saturn’s. Cassini And HiRISE Camera orbit Mars Mars reconnaissance orbit.

JunoCam isn’t really part of Juno’s main science mission. However, the camera serves the main function. Let Juno travel with us.

I think it’s really great. Sometimes astrophotography is more thought of as art than science.

But as an astrophotographer, I believe that this image inspires future scientists, raises a general awareness of ongoing scientific missions and public support for science funding. Speaking of which, what has our science discovered about the largest and greatest worlds?

One of Jupiter’s greatest mysteries is in its heart. Juno helped solve the ongoing debate about how Jupiter formed in the planetary science community.

There were two possibilitiesThe first is that Jupiter began as a rocky world, a nucleus that is about 10 times the mass of the Earth. The gravitational force of this nucleus attracted the surrounding hydrogen and helium until the formation of Jupiter as we know it. Its original rocky world was buried under a swirling vortex.

The second possibility is that the vortex of the rotating circular planetary disk of our early solar system collapsed on its own and Jupiter formed directly without a rocky core. Both theories account for different conditions when the solar system begins. Juno is not a solid core, but “ambiguous” or “Dilution“main point.

Jupiter appears to have been formed from a rock body, but its core is spread throughout Jupiter’s interior rather than being located at the center of the planet.

The dilution of the nucleus appears to be the result of a massive planet-sized impact on Jupiter that broke the initial nucleus and spread it over half the diameter of Jupiter.

Imagine being there for an event like that. Jupiter is swallowing up planets in our solar system that we never knew. The history of our place in space has been revealed.

We also learned that Jupiter’s winds dive deep beneath the outer clouds, the Great Red Spot is hundreds of kilometers deep, and from Jupiter’s North Pole and Antarctica we have seen huge cyclones capable of swallowing the country.

Jupiter is currently the brightest object in the night sky after sunset. If the sky is clear and you can see, look south!

Remember that the bright spot is a huge world hundreds of times the size of the Earth and millions of kilometers away, but potentially one of the key elements of your existence. Jove is amazing.

The Latest Flyby of Jupiter Has Offered Some of The Most Marvellous Views Yet – ScienceAlert

Published

on


Jupiter.

Most massive planet in the solar system – twice that of all the other planets combined. This giant world formed from the same cloud of dust and gas that became our Sun and the rest of the planets.

But Jupiter was the first-born of our planetary family. As the first planet, Jupiter’s massive gravitational field likely shaped the rest of the entire solar system.

Jupiter could’ve played a role in where all the planets aligned in their orbits around the Sun…or didn’t, as the asteroid belt is a vast region which could’ve been occupied by another planet were it not for Jupiter’s gravity.

Gas giants like Jupiter can also hurl entire planets out of their solar systems, or themselves spiral into their stars.

Saturn’s formation several million years later probably spared Jupiter this fate.

Jupiter may also act as a “comet catcher.” Comets and asteroids which could otherwise fall toward the inner solar system and strike the rocky worlds like Earth are captured by Jupiter’s gravitational field instead and ultimately plunge into Jupiter’s clouds.

But at other times in Earth’s history, Jupiter may have had the opposite effect, hurling asteroids in our direction – typically a bad thing but may have also resulted in water-rich rocks coming to Earth that led to the blue planet we know of today.

Jupiter is a window into our own solar system’s past – a past literally enshrouded beneath Jupiter’s clouds which is why Juno, the probe currently orbiting Jupiter, is so named. Juno, Jupiter’s wife in mythology, was able to peer through a cloak of clouds Jupiter used to hide himself and his wrongful deeds.

In this case, however, we are looking through Jupiter’s clouds into our own history. Juno entered orbit of Jupiter 5 July 2016 after travelling for nearly five years to reach the gas giant.

Falling into Jupiter’s gravity well, Juno arrived at a speed of 210,000 km/h, one of the fastest speed records set by any human-made object.

Juno is in a highly eccentric 53 day orbit. During Perijove, or the closest orbital approach, Juno skims Jupiter at an altitude of 4,200 km and then sweeps outward to 8.1 million km. Juno’s orbit is designed to navigate through weaker areas of Jupiter’s incredibly powerful magnetic field.

Second in power only to the Sun itself, Jupiter’s magnetic field accelerates high energy particles from the Sun creating powerful bands of radiation that encircle the planet – electronics-frying radiation.

In addition to its nimble navigation, Juno’s electronics are hardened against radiation with its “radiation vault” – a 1 cm thick titanium shell that houses its sensitive scientific equipment.

One piece of equipment which dazzles all of us back on Earth is JunoCam – an RGB colour camera taking visual images of Jupiter’s clouds as the probe buzzes the planet in just two hours each orbit spending as little time as possible in Jupiter’s radiation.

Most recently, Juno completed Perijove 29 and some of the photos were posted by “Software Engineer, planetary and climate data wrangler, and science data visualization artist” Kevin Gill.

Kevin has an absolutely astonishing Flickr page where he posts images he’s processed from Juno as well as other missions like Saturn’s Cassini and the HiRISE camera orbiting Mars on the Mars Reconnaissance Orbiter.

JunoCam isn’t really part of Juno’s primary scientific mission. But the camera does provide a key function – allowing Juno to bring us along for the journey.

Which I think is truly spectacular. Sometimes astrophotography is thought more of as art than science.

But as an astrophotographer myself, I believe these images inspire future scientists, general awareness of ongoing scientific missions, and hopefully public support for the funding of science. Speaking of which, what has our science discovered about our giantest of giant worlds?

One of the greatest mysteries of Jupiter is what lies at its heart. Juno helped settle an ongoing debate in the planetary science community about how Jupiter formed.

There were two possibilities: The first is that Jupiter began as a rocky world – a core about 10 times the mass of Earth. The gravity of this core drew in surrounding hydrogen and helium until the Jupiter we know of was formed – that original rocky world buried beneath the churning maelstrom.

The second possibility is that eddies in the rotating protoplanetary disk of our early solar system collapsed on themselves and Jupiter formed from them directly with no rocky core. Both theories describe different conditions at the start of our solar system. Juno revealed something stranger, not a solid core, but a “fuzzy” or “diluted” core.

It appears that Jupiter did form from a rocky body, but rather than that core being situated at the centre of the planet, its is spread throughout the interior of Jupiter. 

The core’s dilution is likely the result of a massive planet-sized impact with Jupiter that shattered the initial core and spread it through half of Jupiter’s diameter.

Imagine being present for an event like that – Jupiter swallowing a would-be planet in our solar system we’ve never known. History of our place in space revealed.

We’ve also learned that Jupiter’s winds dive deep below the outer clouds, that the Great Red Spot is hundreds of kilometers deep, and we’ve seen giant cyclones at Jupiter’s North and South Poles that could swallow a country.

Jupiter is presently the brightest object in the night sky after sunset. If you have clear skies and can see it, look South!

Remember, that bright point is a giant world hundreds the times the size of Earth, millions of kilometers away, and yet potentially one of the key factors in your existence. By Jove, that’s amazing.

NASA Astronaut Will Vote From Space – KCCU

Published

on


On Election Day, NASA astronaut Kate Rubins will be more than 200 miles above her nearest polling place. But she’s still planning to vote — from space.

“It’s critical to participate in our democracy,” Rubins told the Associated Press. “We consider it an honor to be able to vote from space.”

Rubins, who has a Ph.D. in cancer biology from Stanford and was the first person to sequence DNA in space, is currently training for her upcoming six-month mission on the International Space Station.

Voting from the space station is similar to voting absentee from anyplace on the planet — except instead of relying on the U.S. Postal Service to deliver the ballot, Rubins will get hers forwarded electronically from Mission Control in Houston.

“Using a set of unique credentials sent to each of them by e-mail, astronauts can access their ballots, cast their votes, and downlink them back down to Earth,” the Smithsonian National Air and Space Museum explained in 2018.

The ballot is then sent to the county clerk for tabulation.

American astronauts have been able to cast ballots from above for over two decades now, ever since a Texas lawmaker learned that astronaut John Blaha couldn’t vote in the 1996 presidential race between Bill Clinton and Bob Dole. At the time, Blaha was serving on Russia’s Mir Space Station, a predecessor to the ISS.

“He expressed a little bit disappointment in not being able to do that,” Republican State Senator Mike Jackson told NPR’s Nell Greenfieldboyce in 2008.

Voting from space had never really been an issue before then, because NASA astronauts typically spent no more than about two weeks on shuttle missions. But with the advent of the space station, Americans were sometimes on missions for months at a time.

So a new law was born. “I can attest to how important one person’s vote is because my first election I won by seven votes out of over 26,000,” Jackson said.

Texas lawmakers approved the measure in 1997, and then-Gov. George W. Bush signed it into law. That same year, astronaut David Wolf became the first American to “vote while you float,” as NASA cheekily put it.

“I voted alone up in space, very alone, the only English speaker up there, and it was nice to have an English ballot, something from America,” Wolf told The Atlantic in 2016. “It made me feel closer to the Earth and like the people of Earth actually cared about me up there.”

Most NASA astronauts live in Houston, so since that Texas law was passed, several astronauts have been able to cast ballots from above. This isn’t even the first time Rubins has exercised her orbital privilege; she also voted in the 2016 presidential election from the space station — listing her address as “low-Earth orbit.”

“I think it’s really important for everybody to vote,” Rubins said. “If we can do it from space, then I believe folks can do it from the ground, too.”
