New computer graphics have been used to debunk the debunkers regarding historic Apollo 11 lunar landing.

Tackling the skeptics out there that the Apollo 11 moon landing in 1969 was a hoax is NVIDIA, a pioneering visual computing and computer graphic enterprise.
By using Maxwell, their new graphics processing unit (GPU) architecture, company experts have debunked the debunkers.
Maxwell is designed to solve some of the most complex lighting and graphics challenges in visual computing. Even on the Moon!
Conspiracy theorists have claimed that the historic mission was performed in a back-lot studio. Part of the crazy claim is that moonwalker Buzz Aldrin must have been lit by something other than the Sun.
Using Maxwell, a demo team rebuilt the scene of the Moon landing in Unreal Engine 4, a game engine developed by Epic Games. They simulated how the Sun’s rays, coming from behind the lander, bounced off the Moon’s surface, and Neil Armstrong’s suit, to cast light on Aldrin as he stepped off the lander.
To recreate the Moon landing, the demo team collected every detail they could.
According to a NVIDIA press statement, their team researched the rivets on the lunar lander, identified the properties of the dust coating the lunar surface, and measured the reflectivity of the material used in the astronauts’ space suits.
Using Voxel-Based Global Illumination, the Apollo 11 landing site was analyzed, determining the way light bounces from one object to another in real time.

Big clue
It was during this research when the demo team uncovered a big clue.
A video clip that showed Aldrin descending the ladder had a bright spot of light that seemed to move every time the camera did.
Using Maxwell to simulate the conditions on the Moon’s surface during the lunar landing 45 years ago, it revealed how Aldrin was illuminated by light reflected from the Moon’s surface and Armstrong’s spacesuit.
Stars in the scene
Another detail seized on by skeptics: photos from the landing site don’t show any stars. That’s led some to claim that the U.S. Government faked the landing and left out the stars in the scene, because it would be impossible to portray the position of the stars from the moon.
By using Maxwell the demo team was able to find them.
“The reason the stars aren’t visible is [that] the exposures in the camera are set to capture the scene on the Moon’s surface,” said Mark Daly, a NVIDIA veteran who led the demo team. “But they’re there. And our demo team was able to find them by digitally changing the exposure on the shots to reveal them.”
Bottom line from the company: “No, the Apollo 11 moon landing wasn’t a hoax. And we can prove it.”

It’s a tight fit – but if you’re sauntering around on Mars that’s a fashion statement.
Space designers at the Massachusetts Institute of Technology are stitching together plans for shrink-wrapping spacesuits. So much so that spacesuits of the future may resemble a streamlined second skin.
The MIT BioSuit is a skintight spacesuit that offers improved mobility and reduced mass compared to modern gas-pressurized spacesuits.
The skintight, pressurized suit would not only support the astronaut, but would give the space traveler much more freedom to move during planetary exploration.
To take the suit off, the wearer would only have to apply modest force, returning the suit to its looser form.
A flyable first: second skin
Master space suit designer at MIT is Dava Newman, a professor of aeronautics and astronautics and engineering systems researchers.
She and her colleagues are one step closer to engineering an active, “second-skin” spacesuit: active compression garments that incorporate small, spring-like coils that contract in response to heat. The coils are made from a shape-memory alloy – a type of material that “remembers” an engineered shape and, when bent or deformed, can spring back to this shape when heated.
The idea is that an astronaut may don a lightweight, stretchy garment, lined with tiny, muscle-like coils. That person would then plug in to a spacecraft’s power supply, triggering the coils to contract and essentially shrink-wrap the garment around the person’s body.

Mobility for planetary exploration
The coil design was conceived by Bradley Holschuh, a postdoc in Newman’s MIT lab.
“Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration,” said Newman in a MIT press statement.
According to Holschuh , while the suit team is concentrating mostly on applications in space, the suit design and active materials may be used for other purposes, such as in athletic wear or military uniforms.
This research was funded by NASA and the MIT Portugal Program.
The MIT Portugal Program is an international collaboration seeking to demonstrate that an investment in science, technology and higher education can have a positive, lasting impact on the economy by addressing key societal issues through quality education and research in the emerging field of engineering systems.

The technical management of the mission — as well as the manufacturing of the probe – is being done by LuxSpace of Luxembourg, an affiliate of OHB AG.
LuxSpace chiefly develops micro satellites and actively participates in the OHB System-led Small GEO initiative.The spacecraft trajectory will be a lunar flyby and return to Earth, with 90 percent chance of re-entry in the Earth’s atmosphere.
The nominal mission duration is 196 hours: 8.17 days.
The nominal lunar flyby will occur on Oct 28, 2014, with the spacecraft slipping over the Moon’s surface at roughly 8,000 miles (13,000 km) distance.
The mission will carry a small number of small scientific instruments: a radio amateur beacon that permits the sending of messages while testing a new approach to locate the spacecraft.

An additional instrument is onboard to yield radiation measurements throughout the satellite’s trajectory around the Moon. The RAD experiment is a special chip from iC-Málaga (Spain) that is able to accurately measure the radiation dose rate.
Further moon missions including landing are planned within the next few years.

NASA Inspector General report appraises U.S. space agency’s NEO program.

NASA’s Office of Inspector General (OIG) has released an informative report that looks at the space agency’s efforts to identify and mitigate near-Earth object (NEO) hazards.
Inspector General Paul Martin released the report that assesses NASA’s efforts to identify and mitigate potential dangers caused by comets and asteroids that approach or enter the Earth’s atmosphere.
This review examines NASA’s NEO Program and assesses the Agency’s progress toward meeting statutory and other Program goals. Specifically, the OIG has taken a hard look at NASA’s allocation and use of resources and plans for the future of the NEO program.
One key finding is that, “even though the Program has discovered, categorized, and plotted the orbits of more than 11,000 NEOs since 1998, NASA will fall short of meeting the 2005 Authorization Act goal of finding 90 percent of NEOs larger than 140 meters in diameter by 2020. We believe the Program would be more efficient, effective, and transparent were it organized and managed in accordance with standard NASA research program requirements.”

Here is a new story from me on something I consider very important:
By Leonard David, Space.com’s Space Insider Columnist

Site J is located on the head of Comet 67P/Churyumov–Gerasimenko. An inset showing a close up of the landing site is also shown.
The primary landing site was chosen from five candidates during the Landing Site Selection Group meeting held on September 13-14, 2014.

The European Space Agency has picked a spot for the Philae lander touchdown on Comet 67P/Churyumov–Gerasimenko.
According to ESA, Site J offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites.
Site J is on the ‘head’ of the comet. The backup landing zone, Site C, is located on the ‘body’ of the comet.
To be released on November 11 by the Rosetta spacecraft, the 220 pound (100 kg) lander will perform in-depth measurements to characterize the comet nucleus.
Following a decade of travel, ESA’s Rosetta arrived at the comet on August 6. By August 24, using data collected when Rosetta was still about 60 miles (100 km) from the comet, five candidate landing regions had been identified for detailed study.
Since then, the spacecraft has moved to within 19 miles (30 km) of the comet.

Stephan Ulamec, Philae Lander Manager at the DLR German Aerospace Center said in an ESA press statement: “None of the candidate landing sites met all of the operational criteria at the 100 percent level, but Site J is clearly the best solution.”It will take around seven hours from the time Philae separates from the ESA Rosetta mother craft until, for the first time ever, a lander will be on the surface of a comet.
When the Philae lander touches down on 11 November 2014, Comet 67P/Churyumov-Gerasimenko will have a landing site waiting for it with a varied but not too rugged landscape offering good solar illumination and hardly any steep slopes.
What name shall be given to Site J?
There will be a public naming competition announced soon.
So get your thinking caps on!
Meanwhile, check out this video showing the landing day that’s ahead:

NASA has announced that the Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater. That’s the rover mission’s long-term prime destination.
Curiosity’s trek up the mountain will begin with an examination of the mountain’s lower slopes.
NASA’s Mars rover Curiosity acquired this image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm, on September 9, 2014, Sol 744 of the Mars Science Laboratory Mission, at 13:57:44 UTC.

In late 2013, the Curiosity team realized a region of Martian terrain littered with sharp, embedded rocks was poking holes in four of the rover’s six wheels.
This damage accelerated the rate of wear and tear beyond that for which the rover team had planned.
In response, the team altered the rover’s route to a milder terrain, bringing the rover farther south, toward the base of Mount Sharp.
This image shows the planned route (in yellow) of NASA’s Curiosity rover from “Pahrump Hills” at the base of Mount Sharp, through the “Murray Formation,” and south to the hematite ridge further up the flank of Mount Sharp.
