China space officials are underscoring the attributes of its Chang’e-5 lunar lander and return sample project.
Chang’e-5 is slated to become the country’s first lunar probe to automatically collect samples, launch on the Moon, and engage in an auto-pilot docking in lunar orbit, according to Hu Hao, the chief designer of the third phase of China’s lunar exploration program.
“The preparation of Chang’e 5 lunar probe is advancing steadily according to schedule,” Hu explains.
Challenges and breakthroughs
As reported by CCTV-Plus, the Chinese craft is scheduled for shipping to the Wenchang launch complex in August, then prepped for launch atop a Long March 5 carrier rocket around November.

Hu notes that there are several challenges and breakthroughs the Chang’e-5 is going to make.
As for the primary task of collecting samples on the Moon, Hu said “one is using a drill. After the probe lands on the Moon, the drill will be used to collect samples beneath the surface. The other is to use a mechanical arm to collect samples on the surface, which contains unique information of the Moon.”
Return leg
Then there’s the return leg from the Moon back to Earth.
“We also have to design a docking in lunar orbit,” Hu added. “After the docking, the samples will be transferred, from the ascending part to the reentry capsule. This is also a complicated process.”

En route from lunar orbit, the reentry capsule is to fly back to Earth at roughly 11.2 kilometers per second.
Important link
Chang’e-5 is an important link in the whole lunar exploration project, Hu notes, a three-step initiative of flying around the Moon, landing on the Moon and returning to Earth.
Chang’e-1 and Chang’e-3 completed the first two steps, with Chang’e-5 set to complete the last step of returning to Earth.
China is readying a Long March-5 rocket for liftoff in the first half of this year. Following that launch, the timing of Chang’e-5’s flight will be determined.
Following a circumlunar voyage in 2014, a return capsule parachuted to Earth. This test was a prelude to China’s Chang’e-5 lunar mission being readied for its return sample mission later this year.

Technology roadmap
“To be realistic, [the lunar probe] will provide our scientists with qualified lunar samples for research, which will enable us to have a deeper understanding of the Moon,” Hu points out. “Technologically, a technology roadmap is necessary because it will be a good technological basis for our following deep space explorations and manned space travels to the Moon and other planets.”
Also on China’s Moon exploration agenda, Chang’e-4 — a backup probe for the Chang’e-3 — is slated to be launched in 2018. That probe is targeted to achieve the first ever soft-landing on the far side of the Moon.

New Shepard is only the first step in fulfilling Blue Origin owner Jeff Bezos’ vision of using ever larger reusable rockets to send an entire economy into Earth orbit and beyond.
The Bezos space business plans follow the recent Elon Musk SpaceX statements regarding their intention to lob two paying customers around the Moon in late 2018 via the company’s Dragon 2 space capsule.
Following the Laureate Award presentations held at Washington’s National Building Museum on March 2, Bezos talked to Aviation Week & Space Technology Editor-in-Chief Joe Anselmo and the audience at the awards dinner about the importance of expanding into the solar system.
Bezos is also slated to speak during SATELLITE 2017, being held March 6-9 in Washington, D.C.

NASA’s Curiosity Mars rover is now completing tasks during Sol 1625 operations.
Lauren Edgar, a research geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona reports: “We’re still at the second stop of the Bagnold Dune campaign,” with the robot running a few more Mars Hand Lens Imager (MAHLI) diagnostics and focusing on targeted remote sensing.
Mt. Sharp observation
Curiosity has on the task list Chemistry and Camera (ChemCam) observation of a ripple crest and a long distance Remote Micro-Imager (RMI) look for changes on the slope of Mt. Sharp.
“We’ll also use Navcam to search for dust devils, and Mastcam will survey the color and opacity of the atmosphere,” Edgar reports.

Also on tap are ChemCam observations of “Allagash” and “Hersey” to investigate some bedrock with interesting color variations.
Mastcam and Navcam will also be used to monitor the atmosphere and search for dust devils.
Ripple activity
On the schedule is use of the robot’s Alpha Particle X-Ray Spectrometer (APXS), continuing to collect data for thermal characterization.

Throughout the plan, Curiosity will repeat several Mastcam and Mars Descent Imager (MARDI) images to monitor changes in sand movement.
“These change detection observations have produced a great dataset that shows some awesome ripple activity,” Edgar concludes.

A multi-disciplinary team at the University of Michigan (U-M) is scoping out a space time capsule.
Called the Michigan Bicentennial Archive (M-BARC) team, their CubeSat work is dedicated to designing, creating, and launching the first ever space time capsule.
It would be an artifact that commemorates the bicentennial of the University of Michigan. The CubeSat must survive the rigors of launch and space for 100 years.

Also, this small satellite would have its own propulsion system. The team is currently comparing electric and chemical thruster systems for use in the CubeSat.
Storing interviews
The student team is gathering content that will be sent up inside the spacecraft. A considerable amount of the project involves collecting representative media from throughout the University, providing the future recipients of the time capsule with an accurate representation of the University and state of Michigan in 2017.
The CubeSat would contain interviews from 1,000 members of the U-M community and an experiment to test DNA as a medium for storing data in space.

Storing 1,000 interviews – and protecting this material from radiation – is not an easy task.
The team is working with the Lurie Nanofabrication Facility at the university to nanoprint 8 to 30 GB of data on a 1-inch silicon chip. At least ten chips will be placed at different orientations in the satellite to provide backups in case of cubesat collisions.
DNA experiment
According to a U-M story on the M-BARC effort, radiation also plays an important role in the team’s DNA radiation experiment which tests the genetic code’s ability to store information in space.
One microgram of DNA can hold 900 terabytes of data, equal to roughly 11,000 iPhones.
The team explains that sending physical packages of information out into the cosmos – like that onboard the Voyager spacecraft — it would be worth finding out if the DNA storage technique works. If so more information can be lobbed into space by this method, contrasted to the Voyager record, or even on solid state drives.

Multidisciplinary
As detailed on the M-BARC website, the multidisciplinary venture involves five distinct sub-teams:
- Bus team is designing the space vehicle itself, as well as the nanoprinting technology that will house our time capsule data.
- Orbit, Launch, and Propulsion team is investigating propulsion methods and determining where the time capsule will be located in space for 100 years.
- Tracking team is devising a way to locate the time capsule from Earth as it orbits for the next century.
- Public Relations team is crafting the content that will exist in the time capsule, managing donations and fundraising, and making sure this project gains momentum at the University of Michigan and beyond.
Location via laser
The team expects construction of at least the payload portion of the CubeSat to begin in the middle of the Winter 2017 semester. The payload includes the DNA experiment and data chips containing interviews.
In due course, say the next century, U-M hopes to retrieve the time-capsule by using a laser to locate the satellite via onboard reflectors.

Deciding on where best to plunk down NASA’s Mars 2020 on the Red Planet rover is not an easy choice, and is spot-on with controversy.
On one hand, the scientific bonus of having a souped-up mega rover meet Martian real estate is one thing. But it turns out that the Mars 2020 stands as a watershed moment, perhaps a bridge to nowhere in Mars exploration planning for NASA.

Multi-Mars probes
Meanwhile, putting aside the tossing of America’s next rover onto the Red Planet, there are other similar efforts in that same time period heading for a Mars landing in 2021, expressly the European Space Agency’s ExoMars 2020 rover, a Chinese Mars lander, as well as Elon Musk’s entrepreneurial enterprise that now intends to lob its first uncrewed Dragon capsule to the Martian surface that same year.

NASA’s Curiosity Mars rover is performing a range of Sol 1623 tasks, with a two-sol plan scoped out that’s devoted to remote sensing and Mars Hand Lens Imager (MAHLI) diagnostics.
The plan is to kick off with arm activities to better understand the fault that MAHLI experienced last week, reports Lauren Edgar, a research geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona.

Interesting color variations
Then the plan involves Chemistry and Camera (ChemCam) investigation of “Dunn Brook.”
“The target shows some interesting color variations so ChemCam will be used to investigate changes in composition,” Edgar explains. “We’ll also acquire a ChemCam observation of “Leighton,” to study the coarse sand grains at the crest of a ripple.”
Also on tap is use of Curiosity’s Navcam to look for dust devils and clouds, in response to orbital observations that suggest recent increasing atmospheric opacity, Edgar adds.

Targeting features
On the second sol, Mastcam is on schedule to acquire a multispectral observation on “Dunn Brook,” and will be used to document the previous Alpha Particle X-Ray Spectrometer (APXS) locations at “Tomhegan” and “Waweig.”
“We’ll also acquire a Mastcam image for deck monitoring to assess the movement of fines, and an upper tier Navcam mosaic to enable us to target features on Mt. Sharp,” Edgar notes.

The second sol plan includes a number of environmental monitoring observations, using both Mastcam and Navcam to monitor the color and opacity of the atmosphere and search for dust devils.
The plan also includes an APXS thermal characterization test and a number of change detection observations.
By the way, Curiosity has taken nearly 391,000 images since its landing in August of 2012.

Transforming Mars to make it more livable for humankind could involve creating an artificial magnetosphere for the Red Planet.
This idea has been suggested by a team of researchers, presenting the concept at the Planetary Science Vision 2050 Workshop 2017 being held this week in Washington, D.C.
Arid and cold
Their paper – A Future Mars Environment for Science and Exploration – notes that today, that planet is an arid and cold world with a very thin atmosphere that has significant frozen and underground water resources.
Mars’ thin atmosphere not only prevents liquid water from residing permanently on its surface and makes it difficult to land missions since it is not thick enough to completely facilitate a soft landing.
The research paper, led by James Green, Director of the Planetary Science Division at NASA Headquarters, explains that when Mars lost its protective magnetosphere, three or more billion years ago, the solar wind was allowed to “directly ravish” the Red Planet’s atmosphere.

Simulation tools
A new approach to greatly enhance Mars’ atmosphere to a higher pressure and temperature can be appraised by a number of existing simulation tools that reproduce the physics of the processes that model today’s Martian climate.
A series of simulations can be used, the research team asserts, to assess how best to largely stop the solar wind stripping of the Martian atmosphere and allow the atmosphere to come to a new equilibrium.
Models hosted at the Coordinated Community Modeling Center (CCMC) can be used to simulate a magnetic shield, and an artificial magnetosphere, for Mars. The CCMC is situated at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
“My approach was to see if we could force nature to do it,” NASA’s Green told Inside Outer Space. “It will be a progress report. But we have some fascinating results already,” he said.
Mars L1
That modeling involves generating a magnetic dipole field at the Mars L1 Lagrange point within an average solar wind environment.
New research is starting to emerge revealing that a miniature magnetosphere can be used to protect humans and spacecraft.

In the future it is quite possible, the research team suggests, that an inflatable structure(s) can generate a magnetic dipole field at a level of perhaps 1 or 2 Tesla (or 10,000 to 20,000 Gauss) as an active shield against the solar wind.
“A greatly enhanced Martian atmosphere, in both pressure and temperature, that would be enough to allow significant surface liquid water would also have a number of benefits for science and human exploration in the 2040s and beyond,” the researchers explain.
“Open air” greenhouses
An enhanced Mars atmosphere, among a list of benefits, would allow larger landed mass of equipment to the surface, shield against most cosmic and solar particle radiation, extend the ability for oxygen extraction, and provide “open air” greenhouses to exist for plant production.
A future Mars protected from the direct solar
wind should come to a new equilibrium allowing an extensive atmosphere to support liquid water on its
surface.

“These new conditions on Mars would allow human explorers and researchers to study the planet in much greater detail and enable a truly profound understanding of the habitability of this planet,” the research team concludes. “If this can be achieved in a lifetime, the colonization of Mars would not be far away.”
The Museum of Contemporary Art on the Moon (MOCAM for short) was conceived in 2016 by visual artist Julio Orta. The concept is seen as a response to the inevitable creation of human communities on the moon in the near future.
According to a MOCAM mission statement:
“Although governments and private entities are working on tourism and colonization of the moon, they seem to have no concern whatsoever for the arts because they are not seen as a source of profit.”
Inaugural show
MOCAM is dedicated in displaying the most interesting, cutting edge, relevant art from the world.
MOCAM is on the watch for emerging artists, new works, and proposals from curators.
An inaugural show, Mystic Hyperstitians in the Heart of Empire, has been curated by Joey Cannizzaro, an undisciplinary artist, curator, and critic. The shows are currently presented on MOCAM’s website.
The intent is that the shows would be on display in the physical museum on the Moon.
Lunar acreage
One small step for art has been taken by Orta last year, procurement of 20 acres on the Moon via LunarLand.com.

According to a “Moon Deed,” the property is located just South of craters Helicon and Leverrier, in an area identified as D6, Quadrant Charlie, Lot Number 1/0581-0600.
LunarLand.com’s website notes that since 1980, over 300 million acres have been sold.
Museum complex
The Moon-based museum architecture has been designed by Mauricio Mastropiero a Mexican architect.
“The Mountain” will be the first component built, and will host a visitor center, temporary galleries, storage areas, dressing rooms, restrooms, sleeping rooms, a restaurant, and a store.
The Moon structure also consists of the “Central Patio.” It is one the main areas for the exhibition of contemporary art. This outdoor esplanade features 480 poles used as structure for a light architecture that can be configured depending on different exhibition needs. This is a space to experience art under the moon’s natural environment.
At the core of the complex is “The Plateau”, a two-story building that levitates using electromagnetic technology. As the principal gallery, the interior of this building also features a controlled atmosphere and hosts the main exhibitions. The second level of this rotating building is the highest point of the museum, a viewpoint to gaze beyond its physical limits.

MOCAM is accepting proposals for 2017 shows.

The NASA Curiosity rover is now departing Sol 1617 activities.
Stuck in the middle on Mars – Curiosity’s right wheel.
That’s the word from Ken Herkenhoff of USGS’s Astrogeology Science Center in Flagstaff, Arizona.
“The drive planned for Sol 1616 halted early, apparently because the right rear wheel got stuck between two rocks,” Herkenhoff reports. “The mobility team concluded that it is safe to continue, so the drive planned for Sol 1617 is essentially the same as the previously-planned drive.”
Layered bedrock
Before the drive, the robot’s Chemistry and Camera (ChemCam) and Right Mastcam were set to observe a sand target named “New Sweden” and Right Mastcam will acquire mosaics of a layered bedrock outcrop dubbed “Hobbstown” and of the dunes that are the target of the drive. measure dust in the atmosphere before the drive begins, Herkenhoff notes.

Meanwhile, a new map of Curiosity’s whereabouts has been issued.
The map shows the route driven by NASA’s Mars rover Curiosity through the 1617 Martian day, or sol, of the rover’s mission on Mars (February 22, 2017).
From Sol 1616 to Sol 1617, Curiosity had driven a straight line distance of about 26.59 feet (8.11 meters). Since touching down in Bradbury Landing in August 2012, Curiosity has driven 9.71 miles (15.63 kilometers).

U.S. House Science, Space, and Technology Committee Chairman Lamar Smith (R-Texas) released the following statement today on NASA’s discovery of the first known system of seven Earth-size planets around a single star, three of which are in the habitable zone.
Public imagination
Chairman Smith: “Space discoveries have long captured the public’s imagination, and NASA’s discoveries like the one today continue to inspire us to explore beyond the boundaries of today,” Smith said.
“The discovery of seven Earth-size planets offers information from uncharted territory that will aid in scientific analysis. As these discoveries continue, we aim to put the United States back on top as a first rate space pioneer. My colleagues and I will ensure that NASA has the tools, resources, and guidance necessary to build upon these new developments and chart new courses space exploration for the next generation,” chairman Smith advised.
Bill in transition
The U.S. Senate recently passed the NASA Transition Authorization Act of 2017 which builds upon years of work by the House Science, Space, and Technology Committee.
“I look forward to seeing this bill pass the House quickly and move to the President’s desk for signature to unlock the mysteries of space as President Trump said in his inaugural address,” Smith concluded.
