The asteroid Itokawa, photographed by Hayabusa.
Itokawa is by far the smallest object featured on this blog, measuring only about 535 metres in length, and less than 300 metres in width and height.  Its surface gravity is tiny (much less than a millimetre per second squared), so the spacecraft entered an orbit round the sun that was roughly parallel to the asteroid’s orbit, here about 7km away.  So the rotation seen in the gif is Itokawa’s rotation, not the result of a camera orbiting around it.
Hayabusa later landed on the surface, collected some dust, and returned it to Earth for analysis.  Google Images doesn’t seem to know of the photos near the surface, so I uploaded most of the good ones to an Imgur album here (edit: Google Images doesn’t recognise the photos I upload to it, but searching for ‘itokawa surface’ brings up some scattered results).  I wouldn’t have guessed that a small asteroid would comprise lots of little rocks, just barely held together by their very weak gravity.  But apparently such rubble piles are common.

The Hackers Who Recovered NASA’s Lost Lunar Photos

Sitting incongruously among the hangars and laboratories of NASA’s Ames Research Center in Silicon Valley is the squat facade of an old McDonald’s. You won’t get a burger there, though–its cash registers and soft-serve machines have given way to old tape drives and modern computers run by a rogue team of hacker engineers who’ve rechristened the place McMoon’s. These self-described techno-archaeologists have been on a mission to recover and digitize forgotten photos taken in the ‘60s by a quintet of scuttled lunar satellites.

The Lunar Orbiter Image Recovery Project has since 2007 brought some 2,000 pictures back from 1,500 analog data tapes. They contain the first high-resolution photographs ever taken from behind the lunar horizon, including the first photo of an earthrise (first slide above). Thanks to the technical savvy and DIY engineering of the team at LOIRP, it’s being seen at a higher resolution than was ever previously possible.

“We’re reaching back to a capability that existed but couldn’t be touched back when it was created,” says Keith Cowing, co-lead and founding member at LOIRP. “It’s like having a DVD in 1966, you can’t play it. We had resolution of the earth of about a kilometer [per pixel]. This is an image taken a quarter of a fucking million miles away in 1966. The Beatles were warming up to play Shea Stadium at the moment it was being taken.”

Between 1966 and ’67, five Lunar Orbiters snapped pictures onto 70mm film from about 30 miles above the moon. The satellites were sent mainly to scout potential landing sites for manned moon missions. Each satellite would point its dual lens Kodak camera at a target, snap a picture, then develop the photograph. High- and low-resolution photos were then scanned into strips called framelets using something akin to an old fax machine reader.

"Now, for the first time in its billions of years of history, our planet is protected by far-seeing sentinels, able to anticipate danger from the distant future – a comet on a collision course, or global warming–and devise schemes for doing something about it. The planet has finally grown its own nervous system: us."

Planet Neptune and its largest Moon Triton

Neptune is the outer most planet in our solar system; it orbits the sun with a radius of 2,798,000,000 miles. Neptune is the 4th largest planet by diameter, 3rd largest planet by mass and densest of all the gas giants. Neptune has a great dark spot similar to that of Jupiter. Both spots are Anticyclonic storms, meaning the winds around the storm flow opposite to the direction dictated by the Coriolis effect. However, unlike Jupiter’s spots, Neptune’s dark spots appear to only last a few years (as opposed to a few hundred) and have relatively calm and cloudless centers. Observations have shown that Neptune spends about the same amount of time with and without its largest dark spot. The storms activity seems to cyclical.

Neptune has 14 moons, Triton is the largest and composes more than 99.5% of all the mass that orbits the planet. Triton is roughly the same size as our moon: (Neptune’s Triton vs Earth’s moon)

Triton has a retrograde orbit around Neptune, meaning that it orbits in the opposite of the planet’s rotation.

These images were taken by the Voyager 2 space probe and the Hubble space telescope, with the exception of the last image being an artists impression of Neptune seen from its moon Triton.

Mars One narrows applicant pool to 1,058 in first cut for 2025 colonization mission
Mars One, the organization attempting to send small teams of astronauts on a one-way trip to Mars, has made its first round of applicant decisions, selecting just over 1,000 people to move on to the next stage of what it hopes will be a decade-long, televised training and colonization mission. Today, 1,058 of the roughly 200,000 people who applied were told that they had made the cut. Between 2014 and 2015, all but a few dozen of those will be weeded out, leaving a final set of four-person teams that will theoretically begin heading to Mars by 2025. Before then, though, there’s a long process of testing, prototyping, and fundraising ahead of the company. 

I hope some of them are Utopians


they will be starting the most planned community in history. UTOPIA HOPE-IA.
