SpooQy-1 action at a distance!

“In the future, our system could be part of a global quantum network transmitting quantum signals to receivers on Earth or on other spacecraft,” says Aitor Villar, lead author of the study. “These signals could be used to implement any type of quantum communications application, from quantum key distribution for extremely secure data transmission to quantum teleportation, where information is transferred by replicating the state of a quantum system from a distance.”

OK, OK, so it’s not the first time quantum entanglement has been demonstrated. But it sure is the smallest. Only 20 cm by 10 cm!

Now we only need a few thousand of these things and a way of somehow making tangled photons actually carry encrypted messages…

(Sorry, thinking of the SF novel I should have published by now…still figuring out the last two chapters!)

See more at New Atlas (note: I seriously doubt the CubeSat actually looks like that picture when it’s doing its thing).

Mars GLOWS green — but brighter at day than at night

By studying Mars’ green glow, the researchers can understand the structure of this layer in the planet’s atmosphere, better understand its altitude range and even observe any changes in reaction to the sun.

First time to see a “green glow” around another planet. In the case of Earth, it’s mostly caused by oxygen, but Mars’ glow is primarily CO2.

So there really ARE “Green Martians.” Just don’t turn and run!

The Once and Future Rings of Mars

The researchers looked at Phobos, which loses height as it interacts with Martian gravity over time. Eventually, its orbit will be too low and Mars will essentially rip it into pieces that form a ring around the planet. It’s estimated that this will happen within 50 million years.

So say goodbye to fear, but dread may stick around a while longer…

Giant asteroid flying by Earth next week looks like it’s wearing a face mask

On April 29, an asteroid estimated to be 1.2 miles wide will fly by Earth, but it’s not on a destructive path. And new images of the asteroid make it appear as though it’s wearing a face mask.

SpaceX to launch 🚀 May 27

Hmm, this doesn’t look much like a dragon… 🐉 🤔

(First NASA manned launch in a decade. First NASA launch by a private company. We’ll likely see many, many more.)

Honey, I Shrunk the Lunar Payloads!

April 13, 2020
MThomas

NASA tells Inverse that the payloads will need to measure no more than 100 millimeters by 100 millimeters by 50 millimeters, around the size of a bar of soap. They will also need to weigh no more than 0.4 kilograms (0.88 pounds) and be able to withstand external temperatures between minus 120 degrees Celsius (minus 184 degrees Fahrenheit) and 100 degrees (212 degrees Fahrenheit). These are the maximum limits, but smaller and lighter is preferred.

Yow, that’s wicked tiny. But small price to pay to set up a Lunar Space Base from which humanity can expand into the expanse.

Er, the solar system. I meant the solar system.

Quasar winds with record energy levels were seen fleeing a distant galaxy

April 1, 2020
MThomas

“The most energetic outflow came from a quasar called SDSS J1042+1646 with 5×1030 gigawatts, or 5 million trillion trillion gigawatts. For perspective, a nuclear reactor puts out about one gigawatt of energy, while the total energy of all Milky Way stars is about 1028 gigawatts.”

Tired of corona-related news. Time to relax with a completely science-based, “you are somewhat insignificant in the greater scheme of things” post.

Enjoy.

I Only Wanted to See You Under the Iron Rain…

IronRain

Wasp-76b, as it’s known, orbits so close in to its host star, its dayside temperatures exceed 2,400C – hot enough to vaporise metals.

Hmm….this reminds me of…let me think for a minute…wait, I got it…

Anakin-TooHot

Yeah, that’s the one. I think.

(Seriously, check it out. Not even the Jedi could possibly handle an actual “inferno” planet.)

Nasa’s 2020 rover: Can we finally answer the big question about Mars?

March 8, 2020

“So, let’s bring the samples back. So if those extraordinary claims are made, they can be verified.”

One likely extraterrestrial form of life might resemble a terrestrial form: the stromatolite.

They basically look like big rocks. I visited one site in Western Australia in 2003 with a group of Japanese students who were told by a local guide that the stromatolites were “3.5 billion years old.” (They’re not, but they do look like what life might have looked like at that point.”

So NASA is sending another rover to see if they can find evidence of a similar life form.

Sorry. No Slurm (yet?).

Five reasons why NASA is sending a Dragonfly to Titan

  1. It’s the only moon in the solar system with a thick atmosphere.
  2. This atmosphere is more similar to Earth’s (especially ancient Earth’s) than any other atmosphere in the solar system.
  3. Chemistry, baby. Microbes, maybe.
  4. Labs take too long. Experiments on Titan would be short.
  5. The terrain is pretty wild.

Check out the link below for more detailed explanations and a neat video.
