In a recent China Central Television (CCTV) interview with Wang Liheng, a senior consultant of the China Aerospace Science and Technology Corporation (CASC) and academician of the Chinese Academy of Engineering, he discussed building a scientific research base on the moon.

“Experts propose that after the three steps for the lunar probe program and the three steps for a manned space program, the two ‘three steps’ can be combined to build a scientific research and development base on the Moon,” Wang said.

People will go to the Moon first to undergo the trials posed by the lunar environment and adapt to it, and then go deeper into space. “The next goal is to send people to the Mars,” Wang said.

Larger carrier rocket

Wang also said in order to carry larger spacecraft into space, China is conducting studies on a heavy-lift rocket which is about 100 meters long and has a diameter of nearly 10 meters with a payload capacity reaching 100 tons.

“The current Long March-5 carrier rocket has a payload capacity of 23 to 25 tons. But in the future, in order to go to the Moon and Mars or even further, a carrier with a larger payload is needed to launch our spacecraft,” Wang said.

Bao Weimin of CASC and an academician of the Chinese Academy of Sciences, also advised CCTV: “The study on the heavy-lift rocket has now reached the stage where further researches on key technologies are being conducted.”

“With heavy-lift rockets, we can realize a larger lunar probe program – a manned lunar landing. It will be completed in 2030 or later,” Bao said.

President trump held a rally in Michigan on April 28…during which he made note of the U.S. space program and private space initiatives.

“We inherit the legacy of the great Americans who constructed the railroads, tamed the frontiers, built the highways, carved out the panama canal, and put a man on the face of the Moon. And by the way, excuse me, do you see how our space program is going? A little different.

And we are letting those rich guys that like rockets — go ahead, use our property, pay us some rent. You can use Cape Canaveral. Just pay us rent and spend that money. Pretty amazing, right?

How about when the engines come down, they come down and they land so they can use them again. That looks like a futuristic, beautiful stuff.

We have reinvigorated our space program to a level that nobody thought possible in this short period of time.

NASA is back. NASA is back. And Mars is waiting for us, you know that. Great. You know what it is? It is great. It is science. It is important. Very important militarily, folks.”

NASA’s Curiosity Mars rover has just started Sol 2036 operations.

“Down the ridge she comes,” reports Michelle Minitti, a planetary geologist at Framework in Silver Spring, Maryland.

Curiosity continues to pick her way downhill off the “Vera Rubin Ridge” and onto the Murray formation rocks below.

“This weekend’s plan only covers two sols,” Minitti notes, “to give Earth planning time and Mars time a chance to realign so that the science team is not up in the middle of the night commanding the rover.”

Nevertheless, the two sols are still full of activities.

Sandy slope

The rover is positioned on a rock-strewn sandy slope, and the science team thought the scattered rocks of the workspace would be better interrogated with Mastcam and Chemistry and Camera (ChemCam) than the robot’s Mars Hand Lens Imager (MAHLI) and the Alpha Particle X-Ray Spectrometer (APXS).

ChemCam targeted “Virginia,” a tan bedrock slab with small nodules, “Shannon Lake,” a red bedrock slab, and “Eveleth,” a block with distinctive layers. One of the advantages of driving backward is that rocks the rover has driven over end up in view of the remote sensing instruments,” Minitti comments.

Mastcam acquired multispectral data from a rock broken by the rover wheels, the target “Britt,” and an expanse of crossbedded outcrop, “Aurora,” to the left of the rover.

Well-preserved scarp

Minitti adds that Curiosity’s Mastcam completed imaging of the “Taconite” crater structure, which the rover has been skirting around the last several sols, with a large mosaic, and captured a single image of a well-preserved scarp in the sand amongst the rocks dubbed “Kinney.”

Dust accumulation

While MAHLI did not see any action over rock targets in the last Sol, the rover is set to image the Rover Environmental Monitoring Station (REMS) ultraviolet sensor, positioned on the rover deck.

“Such MAHLI images keep track of dust accumulation, supporting the observations of the sky made by the sensor,” Minitti points out. “The sky itself will get attention from Mastcam and Navcam, with observations of dust in the atmosphere and dust devils at midday, and observations of dust in the atmosphere and clouds in the early morning,”

High interest targets

After a drive of roughly 165 feet (50 meters), “Curiosity ought to be positioned within sight of two prominent vertical outcrop faces farther east along the Vera Rubin Ridge,” Minitti reports. These are high interest targets for imaging for next week, as the team hopes they provide further insight into the structure and formation of the ridge itself.”

After the drive, the robot’s Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) will conduct an empty cell analysis, “a move in preparation for what the team hopes is acquisition and delivery of a new drilled sample in the not-too-distant future,” Minitti concludes.

Traverse map

A new Curiosity traverse map through Sol 2034 shows the route driven by NASA’s Mars rover Curiosity through the 2034 Martian day, or sol, of the rover’s mission on Mars (April 27, 2018).

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 2032 to Sol 2034, Curiosity had driven a straight line distance of about 90.83 feet (27.69 meters), bringing the rover’s total odometry for the mission to 11.71 miles (18.85 kilometers).

Customers

Below are some of the payload customers that are flying on Mission 8:

  • SFEM-2 is from NASA Johnson Space Center, Houston, Texas. NASA’s Suborbital Flight Experiment Monitor-2, or SFEM-2, is designed to characterize payload test environments in support of the NASA Flight Opportunities program and other payload initiatives. The sensor suite collects cabin environmental data (CO2, pressure, acceleration, acoustics) and also tests components for future flights on NASA’s Orion capsule.
  • Schmitt Space Communicator (SC-1x) Solstar (Santa Fe, NM), developed with private funding. The Schmitt Space Communicator, named after Solstar advisor and Apollo 17 astronaut Harrison “Jack” Schmitt, is a technology demo to test the concept of providing commercial Wi-Fi access to in-space users. This flight test is being conducted with support from NASA’s Flight Opportunities Program.
  • Daphnia from the University of Bayreuth with ZARM (The Center of Applied Space Technology and Microgravity at the University of Bremen) and funding from German space agency, DLR. The Daphnia experiment investigates the effects of microgravity on gene expression and the cytoskeleton of daphnia water fleas. This small invertebrate species is popular in design of future bioregenerative life support systems for human space exploration.
  • EQUIPAGE from Otto von Guericke University (Magdeburg, Germany) with ZARM (The Center of Applied Space Technology and Microgravity at the University of Bremen) and funding from German space agency, DLR. EQUIPAGE studies the motion of macroscopic rod shaped grains to validate physics models of these systems under microgravity conditions. Such “granular gases” allow researchers to study a unique state far from equilibrium and not possible in normal Earth environments.
  • EUPHORIE from University of Duisburg-Essen with ZARM (The Center of Applied Space Technology and Microgravity at the University of Bremen) and funding from German space agency, DLR. EUPHORIE uses a laser to examine the phenomenon of photophoresis, the interaction of light on solid particles suspended in a gas. As the laser heats one side of such particles, it warms nearby gas molecules and accelerates the particle towards its cooler side. This research has applications to the study of early solar system evolution and meteorite formation.

NASA’s Mars rover has just started Sol 2034 science duties. The robot is descending Vera Rubin Ridge reports Mark Salvatore, a planetary geologist at the University of Michigan in Dearborn.

“Curiosity is continuing her march to the north and west, descending through the stratigraphic layers exposed in Vera Rubin Ridge and working her way back towards the unit known as the Blunts Point member, just below the ridge,” Salvatore reports. “Curiosity will continue her investigation of each of these stratigraphic layers, filling in all of the details necessary to interpret the geologic history of this region.”

Local and regional geology

Until then, the rover’s science team is keeping Curiosity busy with additional measurements to better interpret the local and regional geology.

A two-sol plan has been scripted with the robot undertaking a 1 hour and 40 minute science block dedicated to studying the exposed rocky material in front of the rover.

The science block kicks off with Chemistry and Camera (ChemCam) measurements of surface chemistry using the onboard laser and spectrometers.

Small impact crater

Salvatore explains that the targets include “Mesabi,” a textured rock towards the left-front wheel, then “Wakemup Bay,” which appears to be in-place bedrock, and finally “Midway,” a long and narrow rock in front of the rover that has potentially been broken apart by the small impact crater (named “Taconite crater”), to the north of Curiosity.

ChemCam’s high resolution camera will then be used to image a rock on the western rim of Taconite crater (named “Logan”) at very high resolution “to see if it shows any interesting features associated with the impact cratering process itself,” Salvatore adds.

Curiosity’s Mastcam is on tap to be used to image the surrounding area, including all of the ChemCam targets that were analyzed. “In addition, a multispectral image suite will be obtained of Taconite crater’s nearby ejecta field,” Salvatore explains, “as a way to determine whether the composition of the ejecta blocks are at all variable, which may indicate that the subsurface geologic units differ in composition from those closer to the surface. Stay tuned!”

Drive ahead

Following this science block, Curiosity has a drive scheduled of roughly 157 feet (48 meters to the northwest, “which would result in another 10 meters or so of decreased elevation as we near the Blunts Point member,” Salvatore says.

From that point, standard post-drive imaging activities will then occur, obtaining images of the landscape surrounding the rover for both scientific and engineering purposes, as well as a Mars Descent Imager (MARDI) image of the terrain immediately below the rover’s belly.

Downhill from here

A next sol plan has Curiosity using its automated targeting capabilities to retrieve chemistry measurements of a nearby bedrock target.

“Following a nap and a quick chat with one of the Mars orbiters, Curiosity will then have one additional science block that is dedicated to environmental monitoring, including measuring the atmospheric dust concentration and searching for dust devils. This will then bring us to Friday, when the science team will plan for a weekend of activities and a drive that will have Curiosity once again head downhill,” Salvatore reports.

Minnesota names

At this location in Gale crater, the team is naming targets after locations in northeastern Minnesota. The names chosen recently are perfect to use while we’re still on Vera Rubin Ridge, Salvatore points out, as the Mesabi Range is part of Minnesota’s Iron Range, a series of Precambrian (i.e., old!) sedimentary units that are enriched in iron.

Credit: NASA/JPL-Caltech/Univ. of Arizona

“These areas were heavily mined in the early 1900s, and were an important part of Minnesota’s economy at this time. Currently, this area is still being mined for low-grade iron ore known as “taconite” (hence Taconite crater!), a sedimentary rock with significant amounts of iron and other mineral phases,” Salvatore concludes. “Kudos to today’s science team for the relevant names!”

New road map

A new Curiosity road map has been issued.

The map shows the route driven by NASA’s Mars rover Curiosity through the 2032 Martian day, or sol, of the rover’s mission on Mars (April 25, 2018).

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 2030 to Sol 2032, Curiosity had driven a straight line distance of about 55.62 feet (16.95 meters), bringing the rover’s total odometry for the mission to 11.70 miles (18.82 kilometers).

The Policy and Science of Rocket Emissions is a new space policy paper from The Aerospace Corporation’s Center for Space Policy and Strategy. Authors Martin Ross and James Vedda consider the effects of rocket emissions in the atmosphere—what is known, and what is not.

“Rocket emissions inherently impact the stratosphere in a way that no other industrial activity does. This is a fundamental aspect of placing payloads into space using chemical propulsion,” explains the report.

Rocket emissions have largely escaped the scrutiny of international regulatory bodies—but that can change at any time, the just issued paper explains. New policies and regulations could be prompted by a general shift in public perception, by an unintended connection to climate-engineering debates, and by a switch to new propellant types.

Effluent influences

As explained in the report, rockets directly inject combustion products (most importantly, particles) into the stratosphere—a particularly sensitive region that is home to the ozone layer. These emissions deplete the ozone and alter the radiative balance of the atmosphere, the authors say. As a result, they contribute to the complex interactions that determine global climate.

Although the effects are still minor compared with other ozone and climate influences, they could assume much greater significance in the years ahead, with launch rates expected to increase dramatically.

Commentary by William B. Miller, Jr., M.D.

It was the greatest car ad ever conceived. A red Tesla Roadster was launched into space with a jaunty spaceman mannequin at the wheel. As it streaks around our solar system at speeds of seven miles per second, its dashboard screen reads a playful, ‘Don’t panic’.

Initial press coverage was fawning. The biggest question was, “Is this art or advertising?” It was never mentioned that the car and its mannequin are loaded with microbes. There hadn’t even been any real attempt to clean it prior to launch. No big deal. It’s just floating in space and won’t impact a planet for a million years or more. However, its elliptical orbit around the Sun has it crossing Mar’s orbit every 18.8 months. It will often get close.

Credit: Ben Pearson

No one seems to care that this craft will gradually deteriorate over time from the impact of innumerable micrometeorites during its endless loops throughout the solar system. And no one seems to understand that particles of those micrometeorites will ricochet off the car and mannequin and carry bits and pieces of it wherever they go. And no one has noted that on every miniscule bit, there will a new set of traveling companions. Wherever those particles go, associated microbes will now circulate with those particles, some of which will travel outward for light years.

It is actually the same for all the NASA spacecrafts that have ever been launched. To NASA’s credit, they have actually tried to be careful. NASA has been rightfully concerned about the possibility of sending our planetary life out into space. To that end, they enacted rigorous ‘clean’ rooms. Prior to launch, vehicles were carefully scrubbed to get rid of any lurking microbes. When our space craft were launched, they were thought to be sterile.

Unfortunately, what NASA believed to be true, was not. It is now understood that the culture techniques that NASA relied upon to determine sterility were utterly insufficient. In our contemporary era, there are new tools of genetic assessment that permit our identification of a much wider range of microorganisms than in prior decades. In fact, it is now known that fewer than 10% of all microbes can be cultured in the standard manner that NASA was diligently applying. Therefore, the tests that NASA relied upon to issue their declarations of sterility were unfortunately completely inaccurate.

Although the NASA spacecrafts were culture negative upon launch, they were actually abounding with covert microbial life. Furthermore, we now know that many microbes can withstand every rigor of space flight. In the vacuum of space, with its absolute cold and bursts of destructive radiation, humans would instantly die. Yet, some microbes do not, nor do singular small animals, called Tardigrades. These incredibly resilient microscopic eight-legged creatures can withstand all the extremes of space. We know that this is true, since some of them have even survived reentry back to our planet from other space flights.

It is these exact findings that inform us that single most important event in our entire human history is currently transpiring. This unheralded event is the passage of the Voyager 1 and 2 spacecrafts beyond our solar system and exiting into interstellar space. What makes this passage so momentous is that both of these crafts carry life.

As originally envisioned, the mission of the Voyager spacecrafts was to study the outer planets of our solar system. In this regard, that mission has been highly successful. The Voyager craft left Earth in 1977, arrived at Jupiter in 1979, and then passed by Jupiter, Saturn and Uranus, to arrive at Neptune by 1989. Important physical discoveries were cataloged at each planet, such as the magnetospheres of Uranus and Neptune. By mission design, there was never any possibility of return. Instead, the craft were tasked towards an endless continuation into deep space.

Now Voyager 1 is over 13 billion miles from Earth, with Voyager 2 close behind. Currently, they are just at the margin of the heliosphere which is the large zone influenced by our Sun. Thereafter, interstellar space looms and the Sun’s influence rapidly fades.

Although the milestones of the Voyager craft are being minutely detailed, NASA astronomers remain completely mum about the most portentious aspect of this Voyager mission. That silence is not entirely surprising since, until the Tesla car launch, the Voyager mission represents the most egregious example of unintended consequences in human history.

Though this event receives no attention, it is immensely more significant than any war in human history, or any ideology, or all of our art and culture. Without planning to do so, we have launched microbial life from this planet. Now, for endless eons, that tenacious life will be propelled outward into deep space. Everywhere Voyager goes, life will be shed. It is the same, but even more so, for the supremely egotistical Tesla in space. Both are instances of singular technical achievement and delinquent government oversight.

There is a theory of the origin of life that suggests that it began on Earth as an instance of Panspermia. In effect, life on this planet began elsewhere, finding a home here and thriving. Now, without explicit intent, both of the Voyager spacecrafts and the Tesla advertisement have begun the process of seeding of life throughout the Cosmos. In our uniformed hubris, we have become an unintentional agency of Panspermia. Now, in a direct sense, we have become a Cosmic invasive species.

Let it be our earnest hope that we will be forgiven.

There are new partnerships afoot that make the commercial lunar economy a potential actuality. A newly-inked collaboration agreement is geared to commercial Moon missions.

In this instance, the European Space Agency partnered with the U.K.’s Surrey Satellite Technology Limited (SSTL) group and the Goonhilly Earth Station in Cornwall, England.

Goonhilly is an independent, privately-owned business providing a complete range of satellite communications services and a range of space and data related services.

No stranger to lunar exploration duties, Goonhilly beamed the Apollo 11 Moon landing to millions of viewers in 1969. The new partnership, dubbed the Lunar Pathfinder mission – steps forward to implement a sustainable, long-term commercial service that supports lunar scientific and economic development, both for Europe and other nations.

Moon Village support

The intention by Goonhilly is to help catalyze the lunar economy and provide affordable services at the Moon and beyond.

In signing the agreement last week, David Parker, Director of Human and Robotic Exploration at ESA, called the first partnership for providing commercial services in support of lunar missions as enabling ESA to deliver innovative lunar missions at lower costs.

“This commercial partnership is part of a broader ESA innovation plan,” he said, one that “is consistent with the ESA Director General’s wider Moon Village concept, in which actors around the world can contribute in different ways to sustained lunar exploration.”

Ride and phone home

The signed partnership leads to the maturation of the Lunar Pathfinder space segment for a low cost “Ride and Phone Home” capability.

The Lunar Pathfinder mission will offer a ticket to lunar orbit for payloads and nanosats onboard an SSTL lunar mothership spacecraft that provides communications data relay and navigation services between customer payloads and the Goonhilly Earth Station Deep Space ground station.

Private and government-sponsored lunar landers, rovers and surface impactors will also be able to sign up to use the lunar communications and navigation services provided by the mothership either for primary mission operations, to provide additional capacity, or as a back-up service.

For prospecting, exploring, and ultimately utilizing the far side of the Moon, this communications relay service is viewed as a mission enabler, providing the bridge between Earth and the lunar surface.

According to an SSTL statement, the stable elliptical orbit of the mothership will allow for long duration visibility of the Southern Lunar Hemisphere each day, with maximum opportunities for the transmission and reception of data between Earth and the lunar surface.

Alice Bunn, International Director at the UK Space Agency, added that while the new agreement covers missions to the Moon, “there is no reason why we couldn’t see a similar service for Mars in the future.”
