Just for fun, for MTV's anniversary:



Lyrics:

Major Tom (Coming Home)

Standing there alone,
The ship is waiting.
All systems are go.
"Are you sure?"
Control is not convinced,
But the computer
Has the evidence.
No need to abort.
The countdown starts.

Watching in a trance,
The crew is certain.
Nothing left to chance,
All is working.
Trying to relax
Up in the capsule
"Send me up a drink."
Jokes Major Tom.
The count goes on...

4, 3, 2, 1
Earth below us
Drifting, falling.
Floating weightless
Calling, calling home...

Second stage is cut.
We're now in orbit.
Stabilizers up,
Runnning perfect.
Starting to collect
Requested data.
"What will it affect
When all is done?"
Thinks Major Tom.

Back at ground control,
There is a problem.
"Go to rockets full."
Not responding.
"Hello Major Tom.
Are you receiving?
Turn the thrusters on.
We're standing by."
There's no reply.

4, 3, 2, 1
Earth below us
Drifting, falling.
Floating weightless
Calling, calling home...

Across the stratosphere,
A final message:
"Give my wife my love."
Then nothing more.

Far beneath the ship,
The world is mourning.
They don't realize
He's alive.
No one understands,
But Major Tom sees.
"Now the light commands
This is my home,
I'm coming home."

Earth below us
Drifting, falling.
Floating weightless
Coming home...
Earth below us
Drifting, falling.
Floating weightless
Coming, coming
Home...
Home.....

Well we may have answered the question of why we haven't been contacted by Alien civilizations yet - one look at that video and I could see them placing earth off limit.

Wouldn’t be surprised, though, if it turned out that this video was what inspired Elon Musk to launch his Tesla into outer space, sending Starman to roam eternally, lol.

Parker Solar Probe Launch Targeted for Aug. 11


https://blogs.nasa.gov/parkersolarpr...ed-for-aug-11/

Quote:
NASA and its mission partners are targeting Aug. 11 for the launch of the Parker Solar Probe mission to the Sun. The 45-minute launch window will open at 3:48 a.m. EDT.

The spacecraft will launch on a United Launch Alliance Delta IV Heavy rocket from Space Launch Complex 37 on Cape Canaveral Air Force Station in Florida.
Parker Solar Probe Prepares to Head Toward Launch Pad

https://blogs.nasa.gov/parkersolarpr...rd-launch-pad/

Quote:
In addition to using the largest operational launch vehicle, the Delta IV Heavy, Parker Solar Probe will use a third stage rocket to gain the speed needed to reach the Sun, which takes 55 times more energy than reaching Mars.
Here's How To Send Your Name Hurtling Into The Sun This Year

http://www.iflscience.com/space/here...sun-this-year/

Quote:
If you've ever wanted to send a part of you hurtling into the Sun, this is your lucky day. NASA is offering you the chance to send your name rocketing towards our favorite ball of gas aboard the Parker Solar Probe.
Your name, if you fancy it, will be included on a memory card within the probe's payload, traveling at speeds previously unknown to any of your nametags.

At its closest approach, the probe will face temperatures of 1,370°C (2,500°F), but the probe's solar shields will astonishingly keep the payload (including equipment to image the Sun) at around room temperature. So your name will stay cool, don't worry. Unless it's something like "Nigel", which has never been cool in the first place.

Already sent in my name, just for sh1ts and giggles.

This is going to be a really interesting mission. Even though after Earth it's the most important celestial body in the Solar System we tend to ignore it.

I also have to admit that when I read that NASA "wanted to send a part of you hurtling into the Sun" my first thought wasn't your name but a body part like maybe a finger?

Bottom line though is I can't wait to see the pictures!

Maybe this was a case of poor alien targeting?

http://www.foxnews.com/science/2018/...tary-base.html

A meteor hit the earth and exploded with 2.1 kilotons of force last month, but the US Air Force has made no mention of the event.

NASA’s Jet Propulsion Laboratory confirmed an object of unspecified size travelling at 24.4 kilometres per second struck earth in Greenland, just 43 kilometres north of an early missile warning Thule Air Base on the 25th of July, 2018.


As an aside I wonder what the military procedures are for something like this? I hope we're not on a hair trigger alert over on of our bases getting wiped out.

Again this is further proof that the most important infrastructure project humanity can engage in from a precautionary principle standpoint is NOT fighting climate change but deploying an asteroid/meteor detection and deflection system in orbit.

Somebody must have been sleeping on the job:

https://www.nasa.gov/planetarydefense/overview

Quote:
NASA’s Planetary Defense Coordination Office (PDCO) is managed in the Planetary Science Division of the Science Mission Directorate at NASA Headquarters in Washington, D.C.
Quote:
The PDCO relies on data from projects supported by NASA’s Near-Earth Object (NEO) Observations Program. The PDCO also coordinates NEO observation efforts conducted at ground-based observatories sponsored by the National Science Foundation and space situational awareness facilities of the United States Air Force. In addition to finding, tracking, and characterizing PHOs, NASA’s planetary defense goals include developing techniques for deflecting or redirecting PHOs, if possible, that are determined to be on an impact course with Earth. In the event that deflection or redirection is not possible, the PDCO is responsible for providing expert input to the Federal Emergency Management Agency for emergency response operations should a PHO be on an impact course or actually impact the Earth.
NASA's colleagues at the Planetary Society have produced a special series of videos within their Random Space Fact series to educate the public on planetary defense. This one talks about potential deflection methods:

Something else we have detected:

http://www.astronomy.com/news/2018/08/free-range-planet

Quote:
A bizarre rogue planet without a star is roaming the Milky Way just 20 light-years from the Sun. And according to a recently published study in The Astrophysical Journal, this strange, nomadic world has an incredibly powerful magnetic field that is some 4 million times stronger than Earth’s. Furthermore, it generates spectacular auroras that would put our own northern lights to shame.
Quote:
The peculiar and untethered object, succinctly named SIMP J01365663+0933473 (we’ll call it SIMP for simplicity's sake), was first discovered back in 2016.
Quote:
SIMP is a supremely interesting object in its own right, but most importantly, this new research opens the door to future insights into exoplanetary magnetic fields and auroras, as well as aids in the hunt for exoplanets that apparently like their privacy.

A Mysterious, Powerful Force Is Flinging Radio Waves at Us from Deep Space

Quote:
Our universe is teeming with invisible light. Beyond the visible spectrum, space is a colorful mess of radio signals and microwaves fired off by flaring "suns," collapsing stars, crackling magnetic fields, roiling dust clouds and seething black holes.

Then, there's the light nobody understands — mysterious, ultrastrong sparks of energy zipping billions of light-years across the universe from unknown origins, for unknown reasons.

Puzzling pulses like these are sometimes called fast radio bursts (FRBs), because they may last just a few milliseconds. On the morning of July 25, one such burst of mysterious energy whizzed past a new array of radio telescopes nestled in the mountains of British Columbia, Canada, registering one of the rarest radio frequencies ever detected

Yappi, the 2nd paragraph below from the article has an interesting quote about these strange "phenomena":

"Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence," Avi Loeb, a scientist at the Harvard-Smithsonian Center for Astrophysics who was not involved in the discovery, said last year in a statement related to new research on these bursts.

He added that an "artificial origin" of the signals (i.e., extraterrestrial intelligence) is worth considering. Other possible origins include supernovas (exploding stars), supermassive black holes or various other sources of mighty electromagnetic radiation, such as pulsars.

Elon Musk Reveals When SpaceX Will Be Able to Send Humans Into Space

Quote:
SpaceX is gearing up to send humans into space for the first time. On Monday, CEO Elon Musk confirmed a report that claimed NASA estimates the firm will be ready for people-carrying space adventures as early as April next year. While a good sign for the company’s Mars mission, a successful human test flight would also enable a new method of sending people to the International Space Station.

The goal is vital for NASA’s future space station experiments. The agency ended its shuttle program in 2011, and now depends on third party support to reach the station. NASA currently has a contract to use the Russian Soyuz spacecraft that expires on November 2019, and the agency plans to use Boeing or SpaceX to fill the gap. Last week, the agency announced it expects SpaceX to complete an uncrewed test flight in November 2018, followed by a crewed flight in April 2019. Musk confirmed that the company will have the Crew Dragon capsule hardware ready to go by this date.

This is great news provided EVERYONE understands that there is a risk in sending people into space and if the unthinkable should happen it doesn't justify shutting the effort down.

Here's the latest news on the Big Bang Theory and no not the one with Sheldon in it.

https://phys.org/news/2018-08-univer...e-physics.html

Next time you eat a blueberry (or chocolate chip) muffin consider what happened to the blueberries in the batter as it was baked. The blueberries started off all squished together, but as the muffin expanded they started to move away from each other. If you could sit on one blueberry you would see all the others moving away from you, but the same would be true for any blueberry you chose. In this sense galaxies are a lot like blueberries.

Since the Big Bang, the universe has been expanding. The strange fact is that there is no single place from which the universe is expanding, but rather all galaxies are (on average) moving away from all the others. From our perspective in the Milky Way galaxy, it seems as though most galaxies are moving away from us – as if we are the centre of our muffin-like universe. But it would look exactly the same from any other galaxy – everything is moving away from everything else.

To make matters even more confusing, new observations suggest that the rate of this expansion in the universe may be different depending on how far away you look back in time. This new data, published in the Astrophysical Journal, indicates that it may time to revise our understanding of the cosmos.



One way to cut through all the confusion is to just admit that we don't know what we don't know.

I may have spoken to soon:

https://www.space.com/41381-mars-col...-bad-idea.html

This is exciting as it is the first definitive detection of liquid water on Mars, and it is possible that there may be further deep lakes elsewhere on the planet. This means there is a real possibility of current life on Mars.

But while the new discovery may fuel aspiring colonisers’ dreams that the water in the subsurface lake might be usable to sustain a human presence, the reality is very different.

The risk of contamination means we shouldn’t send humans there until we know for sure whether there is naturally evolved life – something that could take years to decades. We will need to drill under the surface and to analyse samples, either in-situ or from material returned to Earth, and find suitable biomarkers to be sure.


Okay, if I'm reading this right the author is saying NO human presence on Mars until we make sure there is NO evolved life on Mars. And he isn't concerned about bringing a nasty microbe back to earth he is concerned about us disrupting a Martian ecosystem.

Net, this guy is proposing the mother of all ENVIRONMENTAL IMPACT studies that could take DECADES before we send humans to Mars. And presumably if we do find evidence of existing life we wouldn't be allowed to ever send humans to Mars?

At one level I get his concern but in the end if we approach exploration in this way whether it's on Mars or the moons of the gas giants, then we will NEVER colonize the solar system. IMO the risk to an existing ecosystem beyond earth is not enough of a reason to condemn humanity to being locked up on Earth.

Let's have a rational debate on this topic with all the cards fully & fairly put out on the table. What we can't do IMO is allow some "expert" to disrupt humanity's natural push to colonize the solar system. To me this represents environmental wackiness of stellar proportions.

Now this is a great example of developing the right skills for saving the Earth in the future:

https://www.space.com/41413-asteroid...-close-up.html

A Japanese sample-return spacecraft just gave its destination asteroid a special close-up. As Hayabusa2 swept to only 1 kilometer (0.6 miles) above the surface of 162173 Ryugu, it spotted boulders, dust and surface features only a few meters or feet across. It's by far the best view of Ryugu since the spacecraft arrived there about six weeks ago.

Several images from Ryugu show the surface of this space rock, which occasionally crosses the orbit of Earth, as it dipped down toward the asteroid. (Scientists classify Ryugu as a potentially hazardous asteroid, but there is no imminent threat to our planet.) In general, studying the surface of small worlds helps scientists better understand solar system history. Engineers can also use the composition information so that, if Earth is threatened by a large asteroid, they can better pick a deflection or destruction method.


There's a couple of cool pictures of the asteroid in the article that are worth checking out. But at some point we're going to need to learn how to land on one of these rocks, drill a hole and plant a nuke. Our lives may depend on it.

You learn something new every day:

https://www.universetoday.com/139738...-support-life/

When looking for potentially-habitable extra-solar planets, scientists are somewhat restricted by the fact that we know of only one planet where life exists (i.e. Earth). For this reason, scientists look for planets that are terrestrial (i.e. rocky), orbit within their star’s habitable zones, and show signs of biosignatures such as atmospheric carbon dioxide – which is essential to life as we know it.

This gas, which is the largely result of volcanic activity here on Earth, increases surface heat through the greenhouse effect and cycles between the subsurface and the atmosphere through natural processes. For this reason, scientists have long believed that plate tectonics are essential to habitability. However, according to a new study by a team from Pennsylvania State University, this may not be the case.



I wasn't aware of the strongly held belief that you needed active planetary plate tectonics for a stable, life supporting atmosphere. The good news is that this work indicates that you probably don't:

After running hundreds of simulations, which varied the planet’s size and chemical composition, they found that stagnant lid planets would be able to maintain warm enough temperatures that liquid water could exist on their surfaces for billions of years. In extreme cases, they could sustain life-supporting temperatures for up to 4 billion years, which is almost the age of the Earth.

NASA on Sunday launched a $1.5 billion spacecraft toward the Sun on a historic mission to protect the Earth by unveiling the mysteries of dangerous solar storms.

"Three, two, one, and liftoff!" said a NASA commentator as the Parker Solar Probe lit up the dark night sky aboard a Delta IV-Heavy rocket from Cape Canaveral, Florida at 3:31 am (0731 GMT).



Anyone get a good view of the meteor shower last night? To much light and clouds where I was.

Love that your article mentions Eugene Parker:

Quote:
The spacecraft is the only NASA probe in history to be named after a living person -- in this case, 91-year-old solar physicist Eugene Parker, who first described the solar wind in 1958.

Parker said last week that he was "impressed" by the Parker Solar Probe, calling it "a very complex machine."

NASA chief of the science mission directorate, Thomas Zurbuchen, said Saturday that Parker is an "incredible hero of our scientific community," and called the probe one of NASA most "strategically important" missions.
How cool would that be to be in his shoes?!



Oh well, I’ll just have to settle for my name being hurtled into the Sun.

As an aside, in terms of visuals, SpaceX does it better, IMO! Wasn’t a fan of NASA substituting their pre-launch animated simulation in place of the live stream, just minutes into the launch. Twitch chatter was hilarious :

“Fake!!”

“Is this VHS?”

“Who made this 1990 PPT?”

“N64 GRAPHICS”

“LOW EFFORT”

“Is this real life?”

Was curious about that myself. I took a look outside last night around 10:30, was clear overhead, but looked like approaching cloud cover moving into the Columbus south side.

Rest in peace Rover:

https://metro.co.uk/2018/08/13/nasa-...ettle-7831488/

Space scientists lost contact with the Opportunity Rover almost two months ago as it was buffeted by a huge dust storm which covered the entire surface of Mars.

The swirling maelstrom will have deposited powder onto the solar panels which power the exploration ‘droid, meaning it cannot recharge its battery to make contact with mission control back on Earth.


Me thinks it's buried under a whole lot of sand.

I don't buy the author of this article's main conclusion but a very interesting read:

https://www.space.com/41435-interste...hallenges.html

The biggest hurdle to mounting an interstellar mission may be humanity's short attention span.



I also wonder what any intelligent species might make of this "fleet" coming at them from out of the void:

It'll take several decades of sustained, focused, coordinated and costly work to pull off a project such as Breakthrough Starshot, which plans to blast fleets of sail-equipped robotic nanocraft toward potentially life-supporting exoplanets at tremendous speeds using powerful, Earth-based lasers.

Might they react as if they're being attacked?

Years ago I read the classic science fiction book "The Forge of God" by Greg Bear:

https://www.amazon.com/Forge-God-Gre.../dp/0765301075

The plot concerns a robotic attack on earth launched by a civilization which had decided to take the precautionary principle to a ridiculous extreme by eliminating ALL intelligent life within a certain distance around their own solar system. They did this by launching robotic fleets to destroy the worlds that housed the potentially rival species.

Space scientists lost contact with the Opportunity Rover almost two months ago as it was buffeted by a huge dust storm which covered the entire surface of Mars.

The swirling maelstrom will have deposited powder onto the solar panels which power the exploration ‘droid, meaning it cannot recharge its battery to make contact with mission control back on Earth.


Me thinks it's buried under a whole lot of sand.

Not according to this commercial celebrating how driven and hard-working we Americans are:

And then, there’s ours (we're still toughening them up):



This stuff just fascinates me.
