Well, now you know. 🤖
Ever wondered what a lunar eclipse on Mars looks like?

Where are your nuclear wessels?
August 11, 2020
Astronauts on a trip to Mars would be exposed to very high levels of radiation which can cause serious long-term health problems such as cancer and sterility. Radiation shielding can help, but it is extremely heavy, and the longer the mission, the more shielding is needed. A better way to reduce radiation exposure is to simply get where you are going quicker.
Hmm. So putting them in a ship with a giant nuclear fission reactor is safer?
I think somebody may want to come up with a backup plan…

Drill, rocket launch, catch, ferry, repeat?
August 2, 2020
The Airbus spacecraft will have to manoeuvre itself into a position to capture these samples that will be packaged inside a football-sized container.
After ingesting this container, the satellite must then prepare it for return to Earth.
This means not only shipping it across hundred of millions of km of space, but also putting the football inside a re-entry capsule that can be dropped into Earth’s atmosphere to land in an American desert.
This would be, indeed, a feat of engineering as well as a first in interplanetary exploration.
But I wouldn’t go so far as to call it an “interplanetary cargo ship.” Unless the intention is to maintain it as a permanent link between research locations (i.e., some kind of permanent orbitor stationed above the Jezero Crater) and research facilities on Earth (or the Moon, or the International Space Station).
Political will is needed in addition to the enormous funding. Semi-privatization, anyone?

Hope Probe Countdown!

The future of Mars (and beyond) is multicultural, multiethnic, and multilingual.
Also, this is a pretty cool website design.
Shooting star above Tokyo
July 4, 2020
“I thought a person living (in the condo) above knocked down a shelf,” wrote one Twitter user, while another said, “I thought my child sleeping on the second floor fell out of bed.”
Granted, the embedded video is only understandable to those who speak Japanese, but even if you don’t, the footage is still cool.
(The sound people heard was likely the result of a small meteorite — about 1 meter wide — breaking the sound barrier as it disintegrated.)

SpooQy-1 action at a distance!
June 30, 2020
“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
June 19, 2020
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
June 17, 2020
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
April 24, 2020
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
April 18, 2020
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.)
