Welcome to the Carnival of Space #111.
Although we start by focusing on lunar lore – including an exclusive interview with the Moon itself – our star trek illuminates many cosmic mysteries, from the core of the Earth to dark matter.
Enjoy the show!
The target on July 16, 1969. (David Haworth)
of Out of the Cradle, arranged for EVA Interviews to go off-world this week to conduct an interview with our Moon as we approach the 40th anniversary of our first visit there and ponder our return, this time for the longer term.
of Cumbrian Sky wonders if NASA’s LRO probe will finally kill off the ridiculous “Apollo Hoax” conspiracy Theory . Stuart looks at why NASA couldn’t possibly have kept such a huge secret – especially for so long! – from some new angles.
of RobotExplorers.blogspot.com describes how MIT Professor Paul Sandorff taught the Interdepartmental Student Project in Systems Engineering in Spring 1967 at Massachusetts Institute of Technology (MIT) in Boston. Sandorff noted that the asteroid Icarus and Earth would pass each other at a distance of four million miles on June 19, 1968. He then asked his students to suppose that, instead of missing Earth on that date, mile-wide Icarus would strike in the Atlantic Ocean east of Bermuda with the explosive force of 500,000 megatons of TNT. Debris flung into the atmosphere would cool the planet and a 100-foot wave would inundate MIT. Sandorff gave his class until May 27, 1967 to develop a plan for averting the catastrophe. Guess what the students proposed to do…

of OrbitalHub.com notes that on June 30, 2009, the Ulysses mission came to an end, one year after the predicted end date. Ulysses is one of the longest space missions to date, and holds the record for the longest running ESA operated spacecraft, with a total mission duration of 6,842 days (18 years, 8 months, and 24 days).
at Cosmic Log checks into the practice sessions for getting the Spirit rover unstuck from its Martian sand trap, and points to some cool movies of a Red Planet sunset and Earth’s motion through Martian skies.
at Universe Today wants you to help find the Mars Polar Lander. Using images from the HiRISE camera on the Mars Reconnaissance Orbiter, see if you can locate the lander that went missing years ago.
at The Martian Chronicles has a post about a handy spreadsheet that he made that calculates the surface temperature, surface gravity, and key orbital parameters of planets
automatically! He also goes into detail about how the temperature calculation is done. Curious about how hot the earth would be if the sun were twice as bright? Or if Earth was where Mercury is? Go play around with the spreadsheet to find out!
highlights Approaching Jupiter from her Astropixie blog. She describes a great animation created by adding images taken by one of the Voyager space crafts, as it approached the planet Jupiter in 1979. Also included is an update of the current status of Voyager 1, the most distant human-made object in space!

offers this beautiful image from the Chandra X-ray Observatory and Canada-France-Hawaii Telescope that gives a new look at Stephan’s Quintet. This compact group of galaxies was discovered about 130 years ago and is located about 280 million light years from Earth.
features “Positrons from Normal, Not Dark Matter, which talks about
the recent work suggesting that gamma-rays observed by Integral did not come from dark matter annihilation.
NextBigFuture provides the latest details on the development of nanoFET propulsion. Nanoparticle field extraction uses tiny thrusters that work much like miniaturized versions of massive particle accelerators. The device uses a series of stacked, micron-thick “gates” that alternate between conductive and insulating layers to create electric fields. These small but powerful electric
fields charge and accelerate a reservoir of conductive nanoparticles, shooting them out into space and creating thrust. NanoFET’s potential for high efficiencies, lower thruster specific mass, effiecient ISP from 100 to 10,000 and longer operational lifetimes are both mission enhancing and enabling.

we honor Apollo 11’s Buzz Aldrin by featuring his stunning vision of the human future on the Moon and Mars: “Buzz Aldrin – A Man for All Maslow Windows!”
