Another casualty of the government shutdown: The Lunar and Planetary Institute in Houston, Texas.

Founded at the height of the Apollo program in 1968, the Lunar and Planetary Institute (LPI) is pushing forward on its celebration this year of the 50th anniversary of Apollo and look to the future.

Still, the message from LPI’s Louise Prockter: “I am closing the LPI today at 5 pm, until further notice. Some staff are fully furloughed, some are partially furloughed. Some of our scientists and educators have grants that will continue to fund them for a while, but the rest of the staff do not have a charge code, unfortunately,” Prockter told Inside Outer Space.

“At some point we will no longer be able to pay even those who have grants, since we are not getting paid by the government. This shutdown is starting to have a significantly negative effect on contractors like ourselves.”

March event

Prockter said that she wants to stress that currently it is a mixture of non, partial and full furloughs (the science staff have grants so are unfurloughed for the next few weeks. Also, she adds that “we still expect the 50th Lunar and Planetary Science Conference (LPSC) to continue as planned.”

That major event is slated for March 18–22, 2019, held at The Woodlands Waterway Marriott Hotel and Convention Center, The Woodlands, Texas. This 4.5-day conference brings together international specialists in petrology, geochemistry, geophysics, geology, and astronomy to present the latest results of research in planetary science.

Although President Trump lifted the government shutdown today, Prockter said she has to go ahead with the furlough plans until receipt of authorization from NASA to continue funding the LPI.

“Hopefully that will come very early next week,” Prockter said.

Cislunar side-step

In a similar predicament is the first lunar In Situ Resource Utilization (ISRU) workshop, “Developing a New Space Economy Through Lunar Resources and Their Utilization:  A Stepped Approach to Establishing Cislunar Commerce Through Science and Exploration.”

It was to be held February 20–22, 2019 at the Universities Space Research Association (USRA) Headquarters in Columbia, Maryland.

“It is unfortunate that the government shutdown in the United States continues unabated. Despite the recent announcement of a temporary funding measure to open the government there is no guarantee that this will become permanent,” explained steering committee member, Clive Neal.

“This situation has had a debilitating effect on our Lunar ISRU Workshop, not only in terms of getting NASA participation, but also support from USRA. At this time, we have no choice but to postpone the workshop,” Neal explained in a statement.

NASA’s Curiosity Mars rover is carrying out Sol 2299 duties.

The robot has moved for the first time since December 13, 2018 moving toward a new geological unit that scientists label as the “Clay-Bearing Unit” (CBU).

Scott Guzewich, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland reports: “Curiosity is continuing the first phase of its journey to the clay-bearing unit…with a series of ‘touch-and-go’ driving sols.”

Melrose place

During these sols, the rover does contact science with its Mars Hand Lens Imager (MAHLI) and Alpha Particle X-Ray Spectrometer (APXS) in the morning, some additional remote sensing as time permits, and then drives away to a new location during the afternoon.

“We want to closely examine the bedrock as we drive to help understand how the Vera Rubin Ridge and the clay unit are related,” Guzewich adds.

“Melrose” was the target for contact science. Additional Mastcam and Chemistry and Camera (ChemCam) observations were taken of other nearby geological targets.

“Curiosity is continuing to monitor a strong late-season dust storm,” Guzewich notes, “that’s increased the amount of dust locally for the last 1-2 weeks with Navcam and Mastcam observations of the atmosphere as well as an increased cadence of [Rover Environmental Monitoring Station] REMS meteorological observations.”

Synergistic, collaborative discoveries

Roger Wiens, a geochemist at the Los Alamos National Laboratory in New Mexico, also notes that the Curiosity rover team, following previous rover teams, has organized itself into different campaigns to explore different geological units.

“Organizers are nominated to lead these campaigns, and their job is to help coordinate among the competing interests of the different instrument teams, helping to make synergistic, collaborative discoveries,” Wiens points out. “The organizers of the CBU campaign have been patiently waiting for their turn to lead the campaign. After all, their first meeting was well over a year ago, on October 3, 2017.”

Geological contact

The rover team is searching for the geological contact between bedrock of Vera Rubin Ridge and that of the Clay-Bearing Unit.

“The precise boundary is not clear from orbit, and it could also be a relatively gradual change as seen from rover images,” Wiens reports. “To have the best chance at observing the transition, Curiosity is doing relatively short drives, interspersed with frequent observations by both remote and contact instruments, as the terrain allows.”

For example, the rover drove about 125 feet (38 meters) over the holiday weekend.

New road map

A new Curiosity traverse map through Sol 2297 has been posted.

The map shows the route driven by NASA’s Mars rover Curiosity through the 2297 Martian day, or sol, of the rover’s mission on Mars (January 22, 2019).

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 2257 to Sol 2297, Curiosity had driven a straight line distance of about 115.54 feet (35.22 meters), bringing the rover’s total odometry for the mission that began in August 2012 to 12.38 miles (19.93 kilometers).

The base image from the map is from the High Resolution Imaging Science Experiment Camera (HiRISE) in NASA’s Mars Reconnaissance Orbiter.

The vehicle carried 8 NASA-sponsored research and technology payloads under the space agency’s Flight Opportunities program. In an upcoming mission, New Shepard will take payloads to space from around the world.

Step by step

From Jeff Bezos of Amazon.com fame and fortune and founder of Blue Origin: “A perfect day. New Shepard has now racked up 10 consecutive successful launches, 9 consecutive successful booster landings, 3 consecutive successful escape tests, and 11 consecutive successful crew capsule landings (including a pad escape),” Bezos explains.

Yesterday’s mission, Bezos adds, “was the 4th flight of this particular tail number — all with minimal refurbishment between flights. Step by step, we’re getting close to human flight. And all of this learning is being incorporated into New Glenn too. I did wear my lucky boots today, but I’m pretty sure it’s actually the incredible Blue Origin team.”

The custom-fitted Under Armour spacesuits “will inspire confidence through comfort and practicality without compromising the natural desire of every Virgin Galactic astronaut both to feel good and look good” as individuals head for the suborbital heights, notes a press statement.

Earth-bound masses

“The full range of apparel and footwear is set to be revealed later this year, ahead of Richard Branson’s inaugural commercial flight,” the Virgin Galactic statement explains.

“In the 1960’s, pop culture declared space ‘the final frontier.’ Over the 50-plus years since space travel began, only 559 people have ever been to space. The game is changing in 2019, as visionaries and leaders come together, innovating to make space accessible to the Earth-bound masses,” observes the Under Armour website.

As the shutdown of the U.S. government continues — and the State of the “Dis-Union” address is under back and forth banter – yet another space causality: A major meeting on Mars Extant Life has gone extinct.

A Mars Extant Life Conference, scheduled next week for Carlsbad, New Mexico has been postponed.

Conference organizers today said it is “with pain and regret” the meeting has been postponed.

Consequences

“The current shutdown of the U.S. government is exacting a toll on increasing numbers of people, and these consequences have now extended to many people involved in this conference.”

Despite a possible resolution of the shutdown, the organizers could not wait any longer.

“Unless something changes, our current estimate is that ~15% of our expected attendees (many of them civil servants) will be unable to attend on our currently scheduled dates.  An additional 35% have sufficient worries or concerns that they have recommended postponing the conference to a later date,” meeting organizers explained.

Nationwide challenges

“Because of financial concerns many of us in the NASA system need to be careful with cash flow. We are seeing nationwide challenges with the airport security system involving the TSA [Transportation Security Administration] workers, and most of our registrants would be travelling by air to the conference venue.  Our conference speakers have started to drop out at an alarming level,” advised the organizers.

“We apologize for the postponement of this conference, which is an action we have not taken lightly,” explained the meeting organizers. “We know all of you have made plans, and that this may cause unwanted disruptions to those plans.  However, this decision seems to result in the greatest good for the greatest number.  We will be in touch with you once things settle down, and we can focus on re-planning.”

Yes, life on Mars – so goes life on Earth.

Japan’s Hayabusa2 continues to make progress in preparing for its first touchdown (TD1) on asteroid Ryugu, planned for the week of February 18.

A backup week is March 4.

Newly posted status reports from the Hayabusa2 team explain that a prolonged injection test of the spacecraft’s thrusters has been conducted. This test is in connection with deploying the small carry-on impactor (SCI) that will create a crater on the space rock.

Seek and hide

After separating the impactor in the SCI operation, Hayabusa2 needs to swiftly hide behind the asteroid to avoid flying debris generated by the SCI explosion.

The recent test checked whether attitude control and the reaction control system (RCS) subsystem functions worked as expected under a strong disturbance that is not usually experienced.

Although the test was run for about half the final injection time, both the attitude control and RCS subsystem worked almost as expected, the Hayabusa2 controllers report, and they acquired valuable data for the actual SCI operation.

Sampler horn

In addition, there’s also been an appraisal of the vibration the sampler horn may encounter.

This vibration test was to confirm that Hayabusa2 will not perform an emergency escape if it incorrectly detects the vibration of the sampler before landing.

With solar conjunction and the New Year holiday now over, Hayabusa2 operations have begun to ramp up.

First was the tour operation, moving Hayabusa2 to a region (so-called BOX-B) that is shifted slightly from the usual home position of the spacecraft – (so-called BOX-A).

A series of scientific observations were carried out, with the Sun directly behind the spacecraft.

From the Hayabusa2 team: “Let’s safely land! Hayabusa2 is working hard to realize the hope of the New Year after a refreshing rest!”

Director of National Intelligence Daniel R. Coats has unveiled the 2019 National Intelligence Strategy (NIS), noting the democratization of space and challenges ahead.

The NIS is the guiding strategy for the U.S. Intelligence Community (IC) and will drive the strategic direction for the Nation’s 17 IC elements for the next four years.

No longer a solely U.S. domain, the democratization of space poses significant challenges for the United States and the IC.

Anti-satellite weapons

“Adversaries are increasing their presence in this domain with plans to reach or exceed parity in some areas. For example, Russia and China will continue to pursue a full range of anti-satellite weapons as a means to reduce U.S. military effectiveness and overall security.”

“Increasing commercialization of space now provides capabilities that were once limited to global powers to anyone that can afford to buy them. Many aspects of modern society—to include our ability to conduct military operations—rely on our access to and equipment in space.”

Lunar building block

3D printing on the Moon is getting a boost thanks to demonstration work by the European Space Agency.

For example, a 1.5 ton block has been 3D printed using simulated lunar dust. The structure spotlights the feasibility of constructing a Moon base using local materials.

The structure was produced using a binding salt as ‘ink’; its design is based on a hollow closed-cell structure – combining strength with low weight, similar to bird bones.

The block was made during an initial feasibility project on lunar 3D printing. ESA has subsequently investigated other types of lunar 3D printing, including solar sintering and ceramics.

Setting up a lunar base could be made much simpler by using a 3D printer to build it from local materials.

Home away from home

While studying lunar base concepts, ESA ran a competition, asking: what would you 3D print on the Moon, to make it feel like home?

Like real flowers and plants, their 3D printed equivalents would be aromatic, to freshen the air, and perform the work of an air recycling unit changing carbon dioxide to oxygen. They would also ‘grow’ as each plant would be made up of smaller components that could be rearranged or added to over time, as if growing in nature.

Responses came from all across the globe, two winners have been selected, both with ideas linked to nature.

The adult category was won by Helen Schell from the UK, proposing a ‘magic Moon garden’, printed from recycled colored plastics. “This is an idea for a colorful carpet of interchangeable color and design, which can be moved and the scale changed wherever you want to site it in your lunar habitat.”

The under 18 category was won by Judith de Santiago, a 17-year-old student from Madrid, Spain, who presented a dodecahedron (or 12-sided) plant pot – ideally for a real plant – that also incorporates symbols of distant Earth. “The blue curves of the bottom represent the waves of the sea,” she explains, “and the green badge with a small plant located at the centre, inspired by Disney’s movie WALL·E, represents the Earth in general.”

Cutting Earth resupply

Global space agencies are considering a lunar base as a possible next step in human space exploration, explains Advenit Makaya, overseeing the lunar 3D printing study.

“3D printing is one of the key building blocks for future space settlement, if we can find ways to make the stuff we need as we go along, rather than rely on costly resupply from Earth,” Makaya adds. “And the Moon, at just a few days away from Earth, represents an ideal test case. Nobody else has run such a detailed system level study, looking at lunar 3D printing of everything from large infrastructure and building blocks down to tiny electronic components.”

The “Conceiving a Lunar Base Using 3D Printing Technologies” project was run by the URBAN consortium led by Germany’s OHB System AG, with extreme environment specialist Comex in France, Austrian space design company Liquifer Systems Group and spacecraft structure manufacturer Sonaca Space in Germany.

International Space Station – Microbial matters.

A new Northwestern University study has found that — despite its seemingly harsh conditions — the International Space Station (ISS) is not causing bacteria to mutate into dangerous, antibiotic-resistant superbugs.

However, the bacteria are instead simply responding, and perhaps evolving, to survive in a stressful environment.

The new findings suggest that the most crucial bacterial functions involved in this potential adaptive response are specific to bacterial lifestyle and do not appear to have direct impacts on human health.

Stressful, harsh conditions

“There has been a lot of speculation about radiation, microgravity and the lack of ventilation and how that might affect living organisms, including bacteria,” said Northwestern’s Erica Hartmann, who led the study.

“These are stressful, harsh conditions,” Hartmann adds in a university press statement. “ Does the environment select for superbugs because they have an advantage? The answer appears to be ‘no.’”

Hartmann is an assistant professor of environmental engineering in Northwestern’s McCormick School of Engineering. The research was published earlier this month in the journal mSystems, a publication of the American Society for Microbiology.

Microbial housing

The ISS houses thousands of different microbes, which have traveled into space either on astronauts or in cargo. The National Center for Biotechnology Information maintains a publicly available database, containing the genomic analyses of many of bacteria isolated from the orbiting outpost.

Hartmann’s team used that data to compare the strains of Staphylococcus aureus and Bacillus cereus on the ISS to those on Earth.

 

Enclosed environments

As the prospect of sending travelers to Mars gain momentum, there has been an increasing interest in understanding how microbes behave in enclosed environments.

“People will be in little capsules where they cannot open windows, go outside or circulate the air for long periods of time,” Hartmann points out. “We’re genuinely concerned about how this could affect microbes.”

Closer to home, Hartmann also notes: “Everywhere you go, you bring your microbes with you. Astronauts are exceedingly healthy people. But as we talk about expanding space flight to tourists who do not necessarily meet astronaut criteria, we don’t know what will happen.”

Research findings

“Based on genomic analysis, it looks like bacteria are adapting to live — not evolving to cause disease,” adds Ryan Blaustein, a postdoctoral fellow in Hartmann’s laboratory and the study’s first author. “We didn’t see anything special about antibiotic resistance or virulence in the space station’s bacteria.”

Although this is good news for astronauts and potential space tourists, Hartmann and Blaustein are careful to point out that unhealthy people can still spread illness on space stations and space shuttles.

An automation process is geared to resolving a key bottleneck in boosting the annual production of Pu-238 toward NASA’s goal of 1.5 kilograms of Pu-238 per year by 2025.

Oak Ridge National Laboratory in eastern Tennessee, near Knoxville, is automating the production of neptunium oxide-aluminum pellets.

 

Pu-238 provides a constant heat source through radioactive decay, a process that has powered spacecraft such as NASA’s New Horizons mission to Pluto and beyond, the Cassini mission to Saturn and the Curiosity Mars Rover.

Upping yearly production

“Automating part of the Pu-238 production process is helping push annual production from 50 grams to 400 grams, moving closer to NASA’s goal of 1.5 kilograms per year by 2025,” said ORNL’s Bob Wham.

Wham adds that the automation tactic is expected to increase the output of pressed pellets from 80 to 275 per week.

Once the pellets are pressed and enclosed in aluminum tubing, they are irradiated at ORNL’s High Flux Isotope Reactor and chemically processed into Pu-238 at the Radiochemical Engineering Development Center.

In 2012, NASA reached an agreement with the Department of Energy to restart production of Pu-238, and ORNL was selected to lead the project.
