Forget all that interstellar outreach to extraterrestrials – like the records on the Voyager spacecraft or the plaques on those Pioneer probes.
Furthermore, you might as well turn a deaf ear on those synthesizer tones used to converse with alien beings in the movie, “Close Encounters of the Third Kind.”

Our human efforts here on Earth to communicate with ET via images or sound are doomed to failure, explains Don Hoffman, professor of cognitive sciences at the University of California, Irvine. And that may be for the best.
Deciphering dilemma
“Even the simplest of images will be misinterpreted,” Hoffman concludes in a paper on interstellar messages.
“We can’t even understand the language of dolphins despite decades of effort,” Hoffman points out. So the chance of aliens deciphering our words is similarly remote: “About zero,” he contends.
“It is not safe…to assume that images intelligible to humans using human rules of visual construction will also be intelligible to intelligent extraterrestrial species using their own rules of visual construction. It is even less safe to assume that intelligent extraterrestrials will use the same rules of cognitive interpretation that we do,” Hoffman writes.

Even the simplest of images will be misinterpreted, Hoffman suggests.
Psychophysical experimentation
His answer to reaching out and touching ET?
We should be prepared to engage, Hoffman suggests, “in the systematic, and potentially time-consuming, process of psychophysical experimentation and theory building that will be required to understand the rules of visual construction of each extraterrestrial species that we encounter.”
Moreover, we should be prepared for similar cross-species anthropological research to understand the rules of cognitive construction of each extraterrestrial species.
“Only then will we be able to construct images that communicate the messages we wish. And these images may look utterly alien to us,” Hoffman adds.
Repeatedly surprised
It is likely that contact with ET will be at a great distance.
“In this case we will not be able to conduct the controlled experiments that are necessary to understand the rules of visual construction used by the extraterrestrials. We will be limited to uncontrolled field studies: analyzing whatever signals we receive from the extraterrestrials and sending signals in return,” Hoffman observes.

It will be tempting in this case, Hoffman asserts, “to assume prematurely that we understand how the extraterrestrials perceive and interpret images and related signals. This could be a serious mistake. Even with species here on earth with which we have coexisted for millennia, we are repeatedly surprised by the results of our controlled experiments.”

Wheeling about on Mars, the Curiosity rover successfully completed a mobility test last week, captured in images of the robot’s wheel tracks through a sand patch.
Curiosity drove roughly 115 feet (35 meters) toward a dune that is now named “Namib.”
“We’ve accomplished a lot of reconnaissance imaging of the dunes, and we’re looking ahead to monitoring the dune slipface and sampling the chemistry and mineralogy of an active dune,” reports Lauren Edgar, a research geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona.

Close-up images of sand grains were taken by Curiosity’s Mars Hand Lens Imager (MAHLI).
Now in Sol 1187, Edgar notes that the plan for the rover included several Chemistry & Camera (ChemCam) and Mastcam observations of the local bedrock at targets named “Rehoboth,” “Hamilton Range,” and “Twyfelfontein.”
“We’re also testing out some software for autonomous target selection. Then we’ll drive towards the “Namib” dune and take post-drive imaging to prepare for future targeting,” Edgar adds.

Devon Island doubles as a welcome mat for revealing safer and more efficient ways to live long and prosper on faraway Mars.
Future Mars explorers are sure to benefit by trekking to a high arctic site here on Earth that in many way offers scenery akin to the Red Planet.
On Devon Island you’ll find firmly planted the Haughton-Mars Project (HMP) – an international multidisciplinary field research venture. The undertaking started in 1997 and has been hosting NASA-supported research each year since then. In its first three years HMP benefited by National Research Council postdoctoral funding.

Rocky barren terrain
Devon Island is the largest uninhabited island on Earth, a wide expanse of landscape that is a rocky barren terrain, set in a polar desert. In terms of human exploration, that locale offers many challenges, from remoteness and isolation to extreme temperatures and lack of infrastructure.

Mum’s the word: The secretive X-37B space plane has winged its way past the 200 day mark, carrying out a classified agenda for the U.S. Air Force.
Rocketed into orbit aboard a United Launch Alliance Atlas V rocket from Florida’s Cape Canaveral Air Force Station back on May 20 of this year, the reusable robotic space plane is also dubbed OTV-4 (short for Orbital Test Vehicle-4).
OTV-4 is the second flight of the second X-37B vehicle built for the Air Force by Boeing Space & Intelligence Systems.
Only two reusable X-37B vehicles have been confirmed as constituting the fleet.
Mini-shuttle
The X-37B space plane looks like a miniature version of NASA’s now-retired space shuttle orbiter. The military space plane is 29 feet (8.8 meters) long and 9.5 feet (2.9 m) tall, and has a wingspan of nearly 15 feet (4.6 m). The spacecraft sports a payload bay about the size of a pickup truck bed.

The Air Force Rapid Capabilities Office (AFRCO) runs the X-37B program.
While the overall duties of the space plane remain secretive, it was previously announced that this craft carries a NASA advanced materials investigation and an experimental propulsion system developed by the Air Force.
Track record
- The first OTV mission began April 22, 2010 and concluded on Dec. 3, 2010, after 224 days in orbit.
- The second OTV mission began March 5, 2011, and concluded on June 16, 2012, chalking up a mission of 469 days.
- The X-37B program completed its third mission on October 17, 2014 following 674 days on-orbit after its December 3, 2012 launch. This last flight extended the total number of days spent on-orbit for X-37B craft to 1,367.
Florida landing?
To date, all flights of the X-37B touched down at Vandenberg Air Force Base in California. When and where OTV-4 will return to Earth is not known.

In 2014, it was announced that Boeing Space & Intelligence Systems had consolidated its space plane operations by making use of NASA’s Kennedy Space Center (KSC) in Florida as a landing site for the X-37B.
According to Boeing, a former KSC space-shuttle facility known as Orbiter Processing Facility (OPF-1) has being converted into a structure that will enable the Air Force “to efficiently land, recover, refurbish and relaunch the X-37B Orbital Test Vehicle (OTV).”

NASA’s Curiosity rover on Mars has been busy carrying out mobility testing, turning and backing out of Martian sand.
The robot documented its moves while taking multiple Hazcam images, then pausing to take Navcam and Mastcam images of the wheel tracks, reports Ken Herkenhoff of the USGS Astrogeology Science Center in Flagstaff, Arizona.
Images were taken to look for changes in a trench wall, and image the spots where the Alpha Particle X-Ray Spectrometer (APXS) was placed on the sand. APXS measures the abundance of chemical elements in rocks and soils.

Dark dune sand
Rover operators were on task to drive the Mars machinery close enough to “High Dune” to allow contact science on the dark dune sand.
This weekend, the plan called for another drive of Curiosity.
Last week, the rover drove a little ways into a sand patch and then backed out, leaving trenches where the wheels were.

Making trenches
“Yes, we’re disturbing some of the very photogenic sand ripples that we have been seeing, but it’s for a good cause,” reports Ryan Anderson, a planetary scientist at the USGS Astrogeology Science Center. “It teaches us more about how well we can drive in that sand, and by using the wheels to make trenches like this, we can get a better idea of the internal structure of the sand ripples,” he added.
Imaging undisturbed sand
Work last week involved contact science on the sand, with images taken by the robot’s Mars Hand Lens Imager (MAHLI) of the undisturbed sand, the walls of the wheel track, and the interior of the track, Anderson said.
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 December 3, 2015, Sol 1182 of the Mars Science Laboratory Mission.

Sir Richard Branson’s Virgin Galactic has introduced an addition to its fleet of vehicles as part of a technical update on its LauncherOne small satellite launch service.
A 747-400 commercial jet aircraft — previously operated by Virgin Atlantic under the nickname “Cosmic Girl” — will provide a dedicated launch platform for the LauncherOne orbital vehicle.

Cosmic Girl went into service in 2001 and will spend her new life as an aerial platform for LauncherOne.
The acquisition of a 747-400 carrier to be the “dedicated air launch” vehicle for LauncherOne is intended to free up WhiteKnightTwo for Virgin Galactic’s human space flight program. That suborbital launch system for paying passengers makes use of the WhiteKnightTwo carrier craft and the SpaceShipTwo rocketship.
Commercial suborbital spaceflight services for ticket holders are to be carried out of Spaceport America in New Mexico.
Rapid service
“Air launch enables us to provide rapid, responsive service to our satellite customers on a schedule set by their business and operational needs, rather than the constraints of national launch ranges,” said George Whitesides, Virgin Galactic CEO in a press statement.
“Selecting the 747 airframe provides a dedicated platform that gives us the capacity to substantially increase our payload to orbit without increasing our prices,” Whitesides added.
Wing modification
The LauncherOne rocket will be mounted to the carrier aircraft under the left wing, adjacent to the position that has been used by other 747s to ferry a fifth engine.
Initial inspections and tests of Cosmic Girl have already been completed and, prior to the start of the wing modification.
A regularly scheduled maintenance check will be conducted by VT San Antonio Aerospace – a maintenance, repair and operations organization.

Launch prices
In September, Virgin Galactic announced it had doubled LauncherOne’s performance to 440 pounds (200 kilograms) into the standard Sun-Synchronous Orbit for a price below $10 million, with the option to purchase further increases in performance to the same orbit and for launches that reach other altitudes or inclinations.
The launch system is capable of launching over 880 pounds (400 kilograms) of payload to other orbits.
Initial inspections
The LauncherOne rocket will be mounted to the carrier aircraft under the left wing, adjacent to the position that has been used by other 747s to ferry a fifth engine.
Initial inspections and tests of Cosmic Girl have already been completed and, prior to the start of the wing modification, a regularly scheduled maintenance check will be conducted by VT San Antonio Aerospace. A maintenance, repair and operations (MRO) organization, VT San Antonio Aerospace has over the years re-delivered more than 3,000 aircraft.
Game-changing customers
According to Virgin Galactic President, Steve Isakowitz: “Our LauncherOne team moved into a 150,000 square foot facility for design and manufacturing, grew to more than 150 dedicated staff, completed multiple long-duration hot fires of our liquid rocket engines, doubled the L1[LauncherOne] payload capacity, and welcomed two game-changing customers from both new space and government, OneWeb and NASA.”

NASA’s next Mars lander has completed assembly and testing at Lockheed Martin Space Systems in Colorado – but one problem. A key science instrument to be carried on the mission is experiencing a problem.
The Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) spacecraft is to investigate processes that formed and shaped Mars.
But one major piece of hardware is experiencing a leak in the vacuum container carrying its main sensors. The sensors are part of an instrument called the Seismic Experiment for Interior Structure (SEIS), which is provided by the French Space Agency (CNES).
Ticking countdown clock
The seismometer is the prime science payload that will help answer questions about the interior structure and processes within the deep Martian interior.
The countdown clock is ticking for a slated blastoff to Mars in March of next year of the lander from Vandenberg Air Force Base, California.
The plan calls for the mission to launch during the period March 4 to March 30, 2016, and land on Mars Sept. 28, 2016.

Bad news
According to a Jet Propulsion Laboratory InSight status report: “The SEIS instrument has three high-sensitivity seismometers enclosed in a sealed sphere. The seismometers need to operate in a vacuum in order to provide exquisite sensitivity to ground motions as small as the width of an atom. After the final sealing of the sphere, a small leak was detected, that would have prevented meeting the science requirements once delivered to the surface of Mars.”
Promising news
A CNES/JPL team is currently working to repair the leak, prior to instrument integration and final environmental tests in France before shipping to the United States for installation into the spacecraft and launch.
The Heat Flow and Physical Properties Package (HP3) from Germany and the rest of the scientific payload for InSight are already installed.
NASA and CNES managers are committed to launching InSight in March and are currently assessing the launch window timeline.

Meanwhile, Lockheed Martin Space Systems is prepared to ship InSight to the Vandenberg AFB launch site. Installation of the seismometer is planned for early January.
The InSight Project is managed by NASA’s Jet Propulsion Laboratory, Pasadena, California. The InSight mission is led by Bruce Banerdt of JPL.
Focus on mission success
In a statement provided to Inside Outer Space from InSight’s builder, Lockheed Martin:
“Lockheed Martin designed and built the InSight Mars lander for NASA on schedule and has recently completed the rigorous environmental testing phase. The spacecraft is now being readied for shipment to the launch site to begin the launch campaign. We understand the importance of this Mars mission and are doing everything possible to accommodate a late delivery of the French Space Agency’s SEIS instrument while still maintaining a focus on mission success.”

The European Space Agency is pressing forward on its 2018 mission to Mars, selecting payloads for the ExoMars surface platform.
That surface platform — which is the responsibility of Roscosmos and the Space Research Institute of Russian Academy of Sciences (IKI) — will remain stationary on the surface of Mars.
Once on Mars in 2019, the ExoMars rover will descend from the platform via a ramp. Then both the rover and platform will begin their scientific operations.
Science priorities
The main science priorities for the surface platform are context imaging of the landing site, long-term climate monitoring, and atmospheric investigations.

Expected to operate for at least one Earth year, the platform will enable imaging of the landing site, monitor the climate of Mars, investigate the atmosphere and analyze the radiation environment. It will also study the distribution of any subsurface water at the landing site, and perform geophysical investigations of the internal structure of Mars.
Landing site prospects
A Landing Site Selection Working Group has recommended the Oxia Planum region for further detailed evaluation for consideration as the primary landing site for the 2018 mission.
A further recommendation was made to also consider Oxia Planum as one of the two candidate landing sites for the backup launch opportunity in 2020, with a second to be selected from Aram Dorsum and Mawrth Vallis.
All three sites bear evidence of having been influenced by water in the past, and are likely representative of global processes operating in the Red Planet’s early history.
First up! ExoMars 2016
The first of the two ExoMars mission is in final preparation for launch next March atop a Russian Proton booster.

ExoMars 2016 consists of the Trace Gas Orbiter that will investigate the possible biological or geological origins of important trace gases in the Martian atmosphere.
Also onboard is Schiaparelli that will be deployed as an entry, descent and landing demonstrator module.

NASA’s Curiosity Mars rover has entered Sol 1180, reconnoitering sand dunes and studying ripples.
Mars Hand Lens Imager (MAHLI) has evaluated the rover’s wheels for damage. An initial assessment showed no broken grousers, explains Ken Herkenhoff of the USGS Astrogeology Science Center in Flagstaff, Arizona.

“The rover is now poised to begin testing mobility in the dark sand in front of the vehicle, but first a table used onboard to determine when heating is needed must be updated,” Herkenhoff adds. “No heating is allowed this sol after the update, which limits the activities that can be planned.”
Recently, making use of Curiosity’s Navcam, a search for clouds was made. Also, there were Chemistry & Camera (ChemCam)/Mastcam observations of a sandy ripple named “Khumib” and an outcrop dubbed “Abenab,” Herkenhoff notes.

ChemCam looks at rocks and soils from a distance, firing a laser that allows analysis of the elemental composition of vaporized materials from tiny areas on the surface of Martian rocks and soils. An on-board spectrograph provides detail about minerals and microstructures in rocks by measuring the composition of the resulting plasma — an extremely hot gas made of free-floating ions and electrons.

Earth’s crater-dotted moon is a graveyard of space probes, hurled there by a number of nations. The search is on for pinpointing the whereabouts of the former Soviet Union’s Luna 9 probe. It was the first survivable landing of a human-made object on another celestial body.
The USSR’s Luna 9 made it to the moon on February 3, 1966. The lander was spherical in shape, less than 2-feet (0.6 meters) in diameter, and weighed around 220 pounds (100 kilograms).
Once coming to full-stop, the vehicle cranked out the first images taken from the moon’s bleak landscape. When pieced together, those pictures offered a panoramic view of the moon’s terrain and the horizon less than a mile away.
On the lunar lookout. Jeff Plescia of The Johns Hopkins University’s Applied Physics Laboratory is sifting through Lunar Reconnaissance Orbiter imagery to pinpoint the former Soviet Union’s Luna 9 spacecraft.
