Space officials from numbers of nations have gathered in Beijing for the Global Space Exploration Conference (GLEX) 2017.
The three-day GLEX 2017 conference, running from June 6-8, will cover an array of topics such as space station development, exploration of the Moon, Mars and near-Earth asteroids and international cooperation. The meeting involves over a thousand delegates from 51 countries.
According to China’s CCTV, Chinese space officials detailed the latest on the upcoming Chang’e-5 and Chang’e-4 lunar probe missions.

China is set to launch its Chang’e-5 lunar probe at the end of November this year, departing from the Wenchang Space Launch Center in south China’s Hainan Province. This ambitious lunar sampling mission is to be hurled moonward atop a Long March-5 booster.
Chang’e-5 is China’s first automated lunar surface sampling, first Moon surface take-off, first automatic docking in lunar orbit, and first return flight at a speed close to the “second cosmic velocity,” according to the China Aerospace Science and Technology Corporation (CASC).
Far side landing
At the GLEX gathering, Liu Jizhong, director of Lunar Exploration and Space Engineering Center of the Chinese Society of Astronautics reported on the Chang’e-4 lunar mission. It will attempt a pioneering first to touchdown on the far side of the Moon.

“We will begin in the third quarter of this year building the protocol of the probe proper and its flight mission is scheduled for next year,” said Liu.
Jan Woerner, Director General of the European Space Agency (ESA) expressed the wish to invite the global space community to join a cooperative Moon Village concept.
Station core module
Meanwhile, as reported by China’s state-run Xinhua news agency, China will carry out at least four piloted spaceflight missions over about five years to build a space station.

China’s first astronaut, Yang Liwei, detailed the plan at GLEX. Yang is deputy director of China’s manned space program office.
Yang said that two piloted space missions will be conducted in 2020. China plans to complete the building of the space station by around 2022, aiming to carry out about a dozen launch missions beforehand, Yang said. He noted that China would launch the first core module of the space station in 2019, followed by launches of two experiment modules.
The space station will enable astronauts to stay in the space for three months to half a year, Yang added. Astronauts are currently preparing for the space station program he said, and that China will start the selection of new astronauts this year.

NASA’s Curiosity Mars rover is busy at work performing Sol 1718 duties.
The robot has started to turn toward the east and southeast as it wheels toward Vera Rubin Ridge, reports Scott Guzewich, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Weighing priorities
After a busy and successful plan over last weekend, Guzewich notes that the rover science team members weighed priorities between using the Alpha Particle X-Ray Spectrometer (APXS) to study the bedrock Curiosity is driving over or drive farther along the path.
Sol 1718 plans took into account that the rover had only gained roughly 10 feet (3 meters) of elevation the robot’s last drive. “We decided to forgo contact science with APXS in favor of extending our drive distance,” Guzewich adds.
Bedrock interest

After a drive of roughly 85 feet (26 meters), the plan calls for post-drive imaging to prepare for the next sol’s activities involving ChemCam, as well as Dynamic Albedo of Neutrons (DAN) and Rover Environmental Monitoring Station (REMS) observations, Guzewich points out.

The Secure World Foundation (SWF) has issued an updated version of the group’s fact sheet on the U.S. Air Force’s X-37B Orbital Test Vehicle.
This fact sheet includes details on the first four flights of the two X-37Bs, including launch and re-entry locations and dates, as well as updated analysis of the various missions the X-37B could potentially be used for while on orbit.

Official objectives of the X-37B program include “space experimentation, risk reduction and concept of operations development for reusable space vehicle technologies.”
The SWF fact sheet notes that “none of the potential missions posited by the U.S. military appear to justify the program’s existence, especially on a cost basis, and this has led to speculation about what the ‘real’ mission may be.”

A Chinese experiment is headed toward the International Space Station (ISS), tucked inside the SpaceX Dragon cargo spacecraft that launched yesterday, June 3.
NanoRacks, a Houston-based company that helps commercial companies make use of the space station, worked with the Beijing Institute of Technology to fly Chinese DNA research to the orbiting outpost.
No commercial Chinese payload has ever flown to the orbiting lab before.
Space radiation
The SpaceX CRS-11 spacecraft is to linkup with the ISS on Monday, if all goes as planned.

China’s Xinhua news agency reported today that the 8-pound (3.5 kilogram) experiment is keyed to answer questions, such as: “Does the space radiation and microgravity cause mutations among antibody-encoding genes and how does it happen?”
The experiment is headed for the U.S. side of the ISS, with Xinhua noting that astronauts there will conduct studies using the device in about two weeks, data from which will be sent back to the Chinese researchers.
Wolf trap
“There is a U.S. law in place, known as the Wolf amendment, that bans cooperation between the U.S. space agency NASA and Chinese government entities, but this deal is purely commercial and therefore considered legal,” Xinhua said.
Chinese Professor Deng Yulin, who led the Chinese research, said that this is the first time an ISS experiment has been independently designed and fabricated in China.
“This cooperation does not violate any laws and regulations, including the Wolf amendment. We do it in an open and visible way,” Deng told Xinhua. “This is a new model of cooperation that we can follow in the future.”
Spirit of the concerns
Inside Outer Space contacted NanoRacks leader for a comment:
“We were careful to honor not only the Wolf Amendment but the spirit of the concerns of some towards working with the Chinese,” Jeff Manber said. “But, via the commercial pathway, we are able to craft a world-class research project that demonstrates the leadership of NASA and the space station in low-Earth orbit,” he said.
Manber said he was pleased to have this first commercial project from China underway “and look forward to carefully building a program that enhances the commercial competitiveness of American companies in space. I also look forward to one day soon working onboard the Chinese space station,” he added.

The European Space Agency (ESA) has launched a new General Studies Program called “Conceiving a Lunar Base Using 3D Printing Technologies.”
At the heart of the study is to find ways of creating habitable structures using all resources available at the destination – the Moon.
The study is looking into additive manufacturing (or 3D printing) technology from a wider perspective, including the ancillary equipment needed to operate this and the high-level requirements to ultimately achieve a lunar habitat.

Additive manufacturing has been identified as one of the most promising applications for building structures on the Moon.
Analyze the possibilities
This new appraisal is to analyze the possibilities of using additive manufacturing for the realization of a lunar base, including:
- production of internal equipment for the crew
- the processing of food based on a limited number of basic elements
- the possibility of making spare parts needed to maintain the base
Past studies have focused on conceptual designs, often based on single elements, rather than taking into account the overall needs in terms of energy, collection and transportation of the regolith, machinery, and so on.

Moonville
ESA’s chief, Johann-Dietrich Woerner, has been vocal regarding the establishment of a “Moon Village.”
“Moon Village is not a single project, nor a fixed plan with a defined time table,” explains Woerner. “It’s a vision for an open architecture and an international community initiative.”
The Moon Village is open to any and all interested parties and nations, Woerner explains. “There are no stipulations as to the form their participation might take: robotic and astronaut activities are equally sought after. You might see not only scientific and technological activities, but also activities based on exploiting resources or even tourism. It is precisely the open nature of the concept that would allow many nationalities to go to the Moon and take part while leaving behind them on Earth any differences of opinion.”

NASA’s Curiosity Mars rover is carrying out Sol 1712 science duties.
Unfortunately the rover’s Sol 1713 activities were not uplinked due to an issue at the Deep Space Network (DSN) station, reports Lauren Edgar, a planetary geologist at the USGS in Flagstaff, Arizona.
A new plan has been scripted, focused on recovering the activities that were planned the previous day, Edgar notes. “The good news is that we’ll be in the same location for the start of the weekend plan, so we’ll be able to add some additional contact science targets at this interesting site.”

Sedimentary structures
The plan kicks off with Curiosity creating Mastcam mosaics of “The Whitecap,” “Trap Rock,” and “Pond Island” to document some nearby sedimentary structures.
Then the Chemistry and Camera (ChemCam) will target “Heron Island” and “McNeil Point” to investigate variations in chemistry within the darker gray rocks in this area, Edgar adds. Also, there will be a ChemCam Remote Micro-Imager (RMI) acquisition to assess the grain size and stratification at “Sols Cliff.”
This will be followed by using the robot’s Navcam to carry out a dust devil survey to monitor atmospheric activity.

Juicy plan
Slightly later in the afternoon, the plan calls for acquisition of a Mastcam mosaic to document the contact science target “Prays Brook” and surrounding rocks, and a multispectral observation will be taken on “Heron Island.”
“The meat of the plan lies in the contact science,” Edgar says.

Edgar concludes that “It’s a juicy plan so I hope it all goes smoothly this time, and we’re looking forward to more contact science tomorrow before we hit the road to Vera Rubin Ridge.”

Traverse map
A newly issued Curiosity’s traverse map through Sol 1712 shows the route driven by Curiosity through the 1712 Martian day, or sol, of the rover’s mission on Mars (May 31, 2017).
Numbering of the dots along the line indicate the sol number of each drive. North is up. The scale bar is 1 kilometer (~0.62 mile).
From Sol 1711 to Sol 1712, Curiosity had driven a straight line distance of about 23.26 feet (7.09 meters), bringing the rover’s total odometry for the mission to 10.28 miles (16.54 kilometers).
The base image from the map is from the High Resolution Imaging Science Experiment Camera (HiRISE) in NASA’s Mars Reconnaissance Orbiter.

Evidence is stacking up from NASA’s Curiosity rover on Mars that an ancient lake in Gale Crater would have provided multiple opportunities for different types of microbes to survive.
Early rover findings point to the presence of a lake more than three billion years old in the crater. New research suggests that the lake had chemical and physical properties very similar and common to lakes on Earth.
Chemical conditions
A new study has defined the chemical conditions that existed in the lake, research that utilized Curiosity’s research tools to determine that Gale Lake was stratified. Stratified bodies of water exhibit sharp chemical or physical differences between deep water and shallow water.
In Gale’s lake, shallow water was richer in oxidants than deeper water.
Chemical conditions that existed in the lake on Mars, a research team reports, could have supported microbial life, including those that thrive in oxidant-rich conditions, those that thrive in oxidant-poor conditions, and those that inhabit the interface between both conditions.

Co-existing environments
“These were different, co-existing environments in the same lake,” said geoscientist Joel Hurowitz, an Assistant Professor in the Department of Geosciences at Stony Brook University. He is lead author of a paper titled Redox stratification of an ancient lake in Gale crater, Mars, set to be published in the June 2 edition of the journal Science.
“This type of oxidant stratification is a common feature of lakes on Earth, and now we have found it on Mars,” Hurowitz added in a university press statement.

Quiet waters
The international team of 22 scientists (co-authors of the paper) also document fluctuations in the climate of ancient Mars.
The method the team used for detecting changes in ancient climate conditions on Mars resembles how ice cores are used to study past temperatures on Earth. It is based on comparing differences in the chemical composition of layers of mud-rich sedimentary rock that were deposited in quiet waters of the lake.

Mars has been found to have had liquid water much longer than previously believed. This new finding further expands the window for when life might have existed on Mars. However, whether this groundwater could have sustained life remains to be seen.
The new finding is reported in a paper published today in Geophysical Research Letters, a journal of the American Geophysical Union.
Halos
This research focuses on lighter-toned bedrock that surrounds fractures and comprises high concentrations of silica — called “halos” — that have been found in Gale crater on Mars.
The true detective is the NASA Curiosity rover. Mosaics of images from the navigation cameras on the wheeled robot show these halos that comprise high concentrations of silica. That indicates liquid groundwater flowed through the rocks in Gale crater longer than previously believed, explains Jens Frydenvang, a scientist at Los Alamos National Laboratory and the University of Copenhagen and lead author of the paper.

Groundwater
“The goal of NASA’s Curiosity rover mission has been to find out if Mars was ever habitable, and it has been very successful in showing that Gale crater once held a lake with water that we would even have been able to drink,” Frydenvang states in a Los Alamos National Laboratory press statement.
Frydenvang adds: “But we still don’t know how long this habitable environment endured. What this finding tells us is that, even when the lake eventually evaporated, substantial amounts of groundwater were present for much longer than we previously thought…thus further expanding the window for when life might have existed on Mars.”
This new study buttresses recent findings by another Los Alamos scientist who found boron on Mars for the first time. Boron also indicates the potential for long-term habitable groundwater in the planet’s past.

The pilot reports: “While both of us were gazing at the spectacle of the moonless sky above with a warm cup of coffee in our hands…suddenly I noticed something in the corner of my eye. I looked to my right and to my own surprise I saw a huge group 7-10 of bright yellow lights move parallel to our track with a much faster speed and very high altitude. This was not an airplane, nor was it a meteorite.”

SpaceX Red Dragon makes use of Supersonic Retro-Propulsion (SRP) to land on Mars.

As 2020 draws closer, look for an armada of international spacecraft launching that have Mars in their respective target sights – including a prospective takeoff of Elon Musk’s SpaceX uncrewed Red Dragon capsule.
Although details of the SpaceX Red Dragon thrust and thirst for Mars is spotty, one landing site is known to be under consideration.
A candidate locale is a lobe of the possibly ice-rich smooth unit in Mars’ Arcadia Region.

Red planet plans
Repeatedly this year, SpaceX front man Paul Wooster has provided some sketchy but captivating Red Planet plans by Musk’s private company.
For example, a few months ago Wooster told a Mars-hungry science audience that an unpiloted SpaceX Red Dragon flight to Mars, able to deliver roughly one ton of useful payload, is being considered for 2020. Indeed, other Red Dragons could follow every two years or so, he said, when Earth-Mars alignments are ripe for the interplanetary crossing.
Rumors have it, but far from confirmed is that SpaceX might be readying two Red Dragons for a Mars 2020-2021 trek. Insiders suggest not.

Express male/female
SpaceX’s Wooster is a lead in the technical development of SpaceX’s Mars architecture and vehicles, including both Red Dragon and human-scale systems. He is also the Manager of Spacecraft Guidance Navigation and Control at SpaceX.
All the pioneering SpaceX work is part of Elon Musk’s express mail thoughts of hurling males and females to colonize the Red Planet.
“First and foremost is to learn how to land large payloads on Mars,” Wooster explains. Experiments carried onboard Red Dragon robotic landers, for instance, are expected to evaluate on-the-spot propellant production. Made-on-Mars oxygen, water and fuel can be processed from icy reserves. Toss in use of the carbon dioxide–rich Martian atmosphere for useful products.

Plop down target
SpaceX has been busily working with NASA and non-NASA landing site experts to plot and pick locales for plopping down a SpaceX Red Dragon.
Meanwhile, SpaceX’s Wooster says that choosing a site is driven by the quantity of water the firm is looking for…and that’s thousands of tons.
One such Red Dragon touchdown place that is “quite promising” Wooster says is Arcadia Planitia, a smooth plain on Mars that appears to have large quantities of ice near the surface.
Ice is nice
Already tapped by SpaceX is the super-sleuth of all Mars orbiting cameras – NASA’s Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment (HiRISE).
HiRise has been used to chart the possible SpaceX Dragon landing site.
“We are following the procedures used for other landing sites” via the Jet Propulsion Laboratory (JPL), Alfred McEwen told Inside Outer Space.
McEwen is the principal investigator for HiRise at the University of Arizona in Tucson. “But this is a candidate site…they haven’t chosen the actual landing site,” he adds.
Ice is nice. That’s the view from Marsologist Chris McKay at NASA’s Ames Research Center. While not expert about Arcadia Planitia, “I can say that low latitude sites with ice that is near that surface will be prime landing site for human exploration. The alternative is go get the water from hydrated minerals like sulfates,” he told Inside Outer Space.
One scientific scenario – could a SpaceX Red Dragon haul back to Earth Mars samples?

Helping hand
Whatever the landing target is for a SpaceX Red Dragon prime, NASA is offering a helping hand, in multiple ways.
NASA is slated to support SpaceX’s 2020 Red Dragon mission with tracking by the Deep Space Network (DSN) throughout the mission, explains Chad Edwards, Manager, Mars Relay Network Office, Chief Technologist, Mars Exploration Directorate at the Jet Propulsion Laboratory in Pasadena, California.
In addition, Edwards points out, NASA’s relay-equipped orbiters (Mars Reconnaissance Orbiter, MAVEN, and Odyssey) will provide high-rate, energy-efficient relay communications for Red Dragon once at Mars, including acquisition of telemetry and tracking data during the critical period of entry, descent, and landing.
Relay support
NASA is particularly interested in Red Dragon’s footed-feel atop Mars terrain that would demonstrate the successful use of Supersonic Retro-Propulsion for the first time at Mars. The DSN would support telemetry and command services throughout the lander’s surface mission, Edwards adds.

“This DSN and Mars relay support to Red Dragon will be provided during a particularly busy period,” Edwards notes, with NASA, the European Space Agency, the Indian Space Research Organization, and the United Arab Emirates ready to hurl hardware Marsward in that same time period. All that Mars machinery is slated to arrive in early 2021.
Also, add in up to nine other missions, from NASA, ESA, and ISRO, already operating at Mars, Edwards explains. “NASA is currently conducting detailed loading studies to assess our ability to meet the telecommunication and tracking needs of all these missions during this period,” he said.
X marks the spot: complex issues
SpaceX getting to Mars is not fraught without perplexing questions.
For instance, won’t supersonic retro propulsion blow away the shallow top soil (50 centimeters depth on average) and expose the ground ice around the lander?
Furthermore, as that ground ice is potentially inhabited and grows at high obliquity, is there a serious problem with planetary protection?
Question: Can SpaceX ignore the planetary protection guidelines?
Additionally, rumors have it that SpaceX is likely to cancel or delay its Mars mission from 2020.
According to Inside Outer Space sources, there is a simple reason:
SpaceX is under pressure from NASA to maintain (or stop slipping) the Commercial Crew Development Vehicle (CCDV) schedule. NASA is extremely anxious to extract itself from the Russian Soyuz dependence. Insiders say that SpaceX has a huge amount of revenue at stake and are in “a precarious cash flow position,” a source said.
One recent decision, apparently, is to descope the propulsive landing on solid ground for the Dragon 2. At least initially, they decided to stick with the proven Dragon 1 parachute landing in water for the initial crew flights. That saves about 6 months of test schedule, Inside Outer Space was advised.
Meanwhile, colonizing Mars looms large on the SpaceX horizon.
