Mars is finally emerging from an ice age that ended 400,000 years ago

Winter is ending.

Mars has many similarities to Earth. There are volcanoes, canyons, craters and - most importantly - water. Oh, and now NASA researchers have added another similarity to the list: ice ages.

Yup, thanks to radargrams taken from NASA’s Mars Reconnaissance Orbiter (MRO), scientists now have physical measurements that suggest Mars is actually just now emerging from an ice age that ended some 400,000 years ago. That’s quite the cold spell!

According to the team, researchers have previously predicted that the Red Planet experienced ice ages in the past using complex computer models, but they lacked actual measurements to back them up.

Fae rogue

I’m a demon arcanist and I’m okay with that.

Terraforming Mars

Spacewalk Friday: Installing a New "Parking Spot" on Station

This Friday, Aug. 19, two U.S. astronauts will install a new gateway for American commercial crew spacecraft at the International Space Station. 

Commercial crew flights from Florida’s Space Coast to the International Space Station will restore America’s human spaceflight launch capability and increase the time U.S. crews can dedicate to scientific research.

The adapter being installed (imaged below) was launched on a SpaceX Dragon cargo spacecraft and arrived on orbit July 20. NASA astronauts Jeff Williams and Kate Rubins will perform the spacewalk to install the equipment this Friday, Aug. 19. This will be the fourth spacewalk in Williams’ career and the first for Rubins.

Four previous spacewalks…like the one below…helped set the stage for installation of this docking adapter. During those previous spacewalks, other crew members laid hundreds of feet of power and data cables outside the space station. 

On Wednesday, the robotics team using the Canadarm2 and its attached “Dextre” manipulator, will reach into the SpaceX Dragon trunk and pull out the docking adapter and position it for Friday’s spacewalk activities.

The morning of the spacewalk, while the astronauts are getting suited up, the robotic arm will position the docking adaptor near the port so that it will be ready for installation.

The two astronauts will venture outside the space station to install the first International Docking Adapter (IDA). This new adapter port will provide a parking space for U.S. Commercial Crew vehicles.

Watch LIVE!

Coverage of the spacewalk begins at 6:30 a.m. EDT on Friday, Aug. 19; with the spacewalk scheduled to begin at 8:05 a.m. EDT. Stream live online HERE.

Do not go gentle into that good night. Rage, rage against the dying of the light.

Even after dozens of spacecraft have been sent to Mars, much remains unknown about that world. Here we have 7 fascinating yet unanswered questions about Mars.

this website pisses me off, everyones always like “space is so cool!” not its not, space is bullshit and i hate everything about it, i genuinely just saw the phrase “a black hole with a mass two billion times the mass of the sun” im so pissed off, shut the fuck up, dont patronise me scientists you know i dont know what the fuck that means, my sad little brain cant comprehend the mass of one sun let alone two fucking billion, i cant even count past 10 without getting confused and youre out here talking about the mass of two billion fucking suns, shut the hell up. and dont even get me started about black holes or the expansion of the universe because thats another two seperate rants entierly. oh and apparently theres a planet made of ice except the ice is also on fire??? yeah sure fucking thing, scientists. and this is just the shit i know about. i purposely dont research space because it pisses me off so much, god knows what other fucking bullshit exists out there that ive yet to read a fucking wikipedia article about. i dont think space is real, literally everything about space is so fucking fake, this is just some elaborate fucking practicle joke. two billion times the mass of the sun, fuck you

ARE MYSTERY MARS PLUMES CAUSED BY SPACE WEATHER?

Mysterious high-rise clouds seen appearing suddenly in the martian atmosphere on a handful of occasions may be linked to space weather, say Mars Express scientists.

Amateur astronomers using telescopes on Earth were the first to report an unusual cloud-like plume in 2012 that topped-out high above the surface of Mars at an altitude around 250 km.

The feature developed in less than 10 hours, covered an area of up to 1000 x 500 km, and remained visible for around 10 days.

The extreme altitude poses something of a problem in explaining the features: it is far higher than where typical clouds of frozen carbon dioxide and water are thought to be able to form in the atmosphere.

Indeed, the high altitude corresponds to the ionosphere, where the atmosphere directly interacts with the incoming solar wind of electrically charged atomic particles.

Speculation as to their cause has included exceptional atmospheric circumstances, auroral emissions, associations with local crustal anomalies, or a meteor impact, but so far it has not been possible to identify the root cause.

Unfortunately, the spacecraft orbiting Mars were not in the right position to see the 2012 plume visually, but scientists have now looked into plasma and solar wind measurements collected by Mars Express at the time.

They have found evidence for a large ‘coronal mass ejection’, or CME, from the Sun striking the martian atmosphere in the right place and at around the right time.

“Our plasma observations tell us that there was a space weather event large enough to impact Mars and increase the escape of plasma from the planet’s atmosphere,” says David Andrews of the Swedish Institute of Space Physics, and lead author of the paper reporting the Mars Express results.

“But we were not able to see any signatures in the ionosphere that we can categorically say were due to the presence of this plume.

“One problem is that the plume was seen at the day–night boundary, over a region of known strong crustal magnetic fields where we know the ionosphere is generally very disturbed, so searching for ‘extra’ signatures is rather challenging.”

To go further, the scientists have looked at the chances of these two relatively rare events – a large and fast CME colliding with Mars, and the mysterious plume – occurring at the same time.

They have been searching back through the archives for similar events, but they are rare.

For example, the Hubble Space Telescope observed a similar high plume in May 1997, and a CME was registered hitting Earth at the same time.

Although that CME was widely studied, there is no information from Mars orbiters to judge the scale of its impact at the Red Planet.

LOL oh @claraxbarton you know me SO well! 

I’ve totally got the first ep on my DVR - I just haven’t had time to watch it lol
