Now in Sol 1593, NASA’s Curiosity Mars rover is set to carry out an agenda of science duties.
The Red Planet robot drove 26 feet (8 meters) on Sol 1591, with this weekend’s plan calling for additional driving.
Curiosity has carried out a wheel inspection, images that show damage given the one-ton rover’s rolling over Martian rocks since landing.

Three sol plan
The three-sol plan — 1593-1595 — starts with a few data management activities for Mastcam and the robot’s Mars Hand Lens Imager (MAHLI), and a recovery sequence to restart the Chemistry & Camera (ChemCam) after it was marked “sick,” reports Lauren Edgar, a research geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona.

Also on tap is taking Mastcam mosaics of “Dead River” and “Boil Mountain” to investigate laminations within the Murray formation and provide some context imaging of the “Misery” outcrop.
Edgar reports that this duty will be followed by use of MAHLI and the Alpha Particle X-Ray Spectrometer (APXS) to study “Misery” and “Dead River,” with an overnight APXS integration on “Misery.”

Atmospheric opacity
On the second sol, Curiosity is to wake up early for some environmental monitoring observations, including some Navcam movies and Mastcam imaging to assess atmospheric opacity, Edgar adds.
The plan calls for another Mastcam mosaic of “Ireson Hill” to document the stratigraphy with long baseline stereo imaging.

Contact science
The third sol includes additional environmental monitoring, a drive, post-drive imaging for targeting, and preparing for more contact science.
Edgar says that Curiosity will also perform a Sample Analysis at Mars (SAM) Instrument Suite evolved gas experiment to use the residual derivatization vapor in the sample manipulation system.

A satellite is slated for launch later this year that will conduct plant growth experiments in both lunar and Martian gravity.
The spacecraft is Eu:CROPIS – short for Euglena and Combined Regenerative Organic-food Production in Space. Eu:CROPIS is an experiment by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
Rotational force
During its mission, the Eu:CROPIS spacecraft will rotate around its own axis at an altitude of over 370 miles (600 kilometers), initially producing the gravitational force of the Moon within it for six months, and will then replicate Martian gravity for another six months.
During this time, tomato seeds will germinate and grow into small space tomatoes under the watchful eye of 16 cameras.

An entire group of microorganisms contained in a trickle filter will use synthetic urine to produce a nourishing fertilizer for the tomatoes; euglena will also be transported on board to supply the hermetic system with additional protection against excess ammonia and to produce oxygen.
LED light will be used to provide the day/night rhythm that the euglena and tomato seed require. A pressure tank will replicate the Earth’s atmosphere.
Local source of fresh food
The satellite, to be lofted via a SpaceX Flacon 9 booster this year, will be controlled by the German Space Operations Center (GSOC), which is operated by DLR in Oberpfaffenhofen near Munich, while the ground station in Weilheim, among others, will handle communications.
“Ultimately, we are simulating and testing greenhouses that could be assembled inside a lunar or Martian habitat to provide the crew with a local source of fresh food,” explains DLR biologist Jens Hauslage, head of the scientific part of the mission in a press statement. “The system would do this by managing the controlled conversion of waste into fertilizer.”

Hauslage notes that in a lunar habitat, for instance, the greenhouse would be located in the astronauts’ ‘home’ in a simulated Earth atmosphere. Urine would be one of the waste products the astronauts would produce in abundance. Here, the plants would have to adapt to reduced gravity conditions – the gravitational pull on the Moon is approximately one sixth of what it is on Earth, and on Mars it is around one third.
Space test of technology
Once Eu:CROPIS and its scientific payload reach space, the first stage will be to activate the greenhouse that will simulate a lunar environment. The second greenhouse with Martian gravity will be activated six months later.
By this time, the microorganisms, tomato seeds and euglena will have been exposed to cosmic radiation for six months. That’s the equivalent to a flight to Mars. The DLR Institute of Aerospace Medicine will measure the radiation exposure inside and outside the satellite throughout the entire mission.

“We are using Eu:CROPIS to space test technology for use in habitats on other celestial bodies, but it could be installed just as well in a terrestrial setting,” says Hauslage.
For instance, trickle filters can be fitted to make manure more effective and less odorous. Recycling urine in conurbations, for instance in greenhouses installed in high-rise buildings (vertical farms), would be another possible use.

NASA’s Curiosity Mars rover is carrying out science duties during Sol 1591.
The Sol 1589 and Sol 1590 plan went well, with the robot wheeling roughly 102 feet (31 meters).
Still sick
Curiosity’s Chemistry & Camera (ChemCam) remains “sick” and some diagnostic activities are being planned for the upcoming weekend, reports Ryan Anderson, a planetary scientist at the USGS Astrogeology Science Center in Flagstaff, Arizona.

“We are approaching the Bagnold Dunes,” Anderson adds, “so in order to save time and allow more room for science activities at the dunes, today’s plan does not include a drive.”
Wheel inspection
Instead, on the plan is a Mars Hand Lens Imager (MAHLI) check-up of the rover wheels.

Prior to that wheel inspection, the Sol 1591 plan starts with Alpha Particle X-Ray Spectrometer (APXS) and MAHLI of the bedrock target “Munsungun,” followed by Mastcam of “Daniel Island” and “Chapman.”
Short bump
“After the MAHLI images of the wheels, we will do a short ‘bump’ drive to get in position for weekend science,” Anderson says.
Curiosity’s Sample Analysis at Mars (SAM) Instrument Suite is slated to do an evolved gas experiment overnight.
Then on Sol 1592, the robot’s Navcam is scheduled for a dust devil search and Mastcam has some multispectral images of Hematite Ridge.

Mastcam also has a small stereo mosaic of “Maple Mountain.”
Driving distance
A map the Curiosity rover’s location for Sol 1589 was released on January 25.
The map shows the route driven by NASA’s Mars rover Curiosity through the 1589 Martian day, or sol, of the rover’s mission on the Red Planet that began in August 2012.
Numbering of the dots along the map line indicate the sol number of each drive. North is up.

From Sol 1587 to Sol 1589, Curiosity has driven a straight line distance of about 94.78 feet (28.89 meters).
Since touching down in Bradbury Landing in August 2012, Curiosity has driven 9.53 miles (15.34 kilometers).

NASA’s Curiosity Mars rover is performing science duties as it works its way through Sol 1589.
This past weekend saw the robot drive roughly 92 feet (28 meters), reports Ryan Anderson, a planetary scientist at the USGS Astrogeology Science Center in Flagstaff, Arizona.

Heavy on observations
The plan for Sol 1589 has the rover continuing its slow ascent of Mt. Sharp. Curiosity’s Chemistry & Camera (ChemCam) remains in a “sick” condition, with ground teams trying to sort out the error that occurred last week.
The upshot is that the robot’s Sol 1589 science block is heavy on Mastcam observations.

After Navcam does an observation to watch for dust devils, Ryan adds that Mastcam will collect mosaics of the targets “Cape Elizabeth,” “Mount Battle,” “Mount Blue,” and “Hematite Ridge.”
Squeezing between rocks
Following this planned duty, Curiosity’s Alpha Particle X-Ray Spectrometer (APXS) is slated to measure the composition of “Cape Elizabeth” and the Mars Hand Lens Imager (MAHLI) is on tap to take supporting pictures.
Once the robot’s arm activity is done the rover will drive about 98 feet (30 meters), squeezing between a couple of large rocks, Ryan notes, toward some bedrock that looks good for more contact science.

Work is underway in China to carry out the first Moon-sample return to Earth mission in over four decades.
Liftoff of Chang’e-5 is to occur at the end of November, according to the Xinhua news agency. The robotic craft is to ride atop China’s Long March-5 booster, departing from the Wenchang Space Launch Center in southern China’s Hainan Province.
Four-part probe
According to Chinese news services, the over 8-ton Chang’e-5 is comprised of four parts: the “orbiter” “lander” “ascender” and a “returner” – an Earth reentry module.

The mission will be China’s first automated Moon surface sampling probe, a mission that involves the first robotic docking in a lunar orbit to transfer collected lunar samples for return to Earth.
The lander will place lunar samples in a vessel in the ascender after the Moon landing. Then the ascender will take off from the lunar surface to dock with the orbiter and the returner orbiting the moon, and transfer the samples to the returner.
The orbiter and returner then head back to Earth, separating from each other far from Earth, with the returner module reentering and parachuting to Earth.

Past history
If successful, the Chang’e-5 mission would be the first lunar sample return to Earth in over 40 years.
The former Soviet Union successfully executed three robotic sample return missions: Luna 16 returned a small sample (101 grams) from Mare Fecunditatis in September of 1970; February 1972, Luna 20 returned 55 grams of soil from the Apollonius highlands region; Luna 24 retrieved 170.1 grams of lunar samples from the Moon’s Mare Crisium (Sea of Crisis) for return to Earth in August 1976.
Relay station
China plans to fulfill three strategic steps with the launch of Chang’e-5, “orbiting, landing and returning.”
The first spacecraft of China’s Moon program, the Chang’e 1 lunar orbiter, was launched in 2007, after which Chang’e 2 was launched in 2010. Chang’e 3, included a lander and rover and was launched in December 2013, successfully soft-landing on the Moon.

Also on the country’s Moon exploration schedule is the launch of the Chang’e-4 lunar probe around 2018.
Chang’e-4 is designed to make the first soft landing on the far side of the Moon, and to conduct an in situ and roving detection and relay communications at the Earth-Moon L2 point, according to the China National Space Administration.
“The country plans to send robots to explore both lunar poles,” said the administration’s vice director Wu Yanhua late last year, adding that plans to send astronauts to the Moon were also being discussed, according to the Xinhua news agency.
Human exploration
Also last year, Tian Yulong, chief engineer of the State Administration of Science, Technology and Industry for National Defense (SASTIND) noted that “lunar exploration is endless.”
Tian said that China is in discussion with the European Space Agency and other countries “to build bases and carry out scientific investigations on the Moon, which will lay a technology and material foundation for human beings’ landing on the Moon in the future.”

NASA’s Curiosity Mars rover is now at work on its Sol 1587 agenda.
The robot drove 43 feet (13 meters) back on Sol 1585, placing the Mars machinery in a good position for contact science.
“But the telemetry also showed that ChemCam [Chemistry & Camera] had been marked ‘sick,’ so we will not be able to use ChemCam this weekend while the problem is diagnosed,” notes Ken Herkenhoff of the USGS Astrogeology Science Center in Flagstaff, Arizona.
Full weekend plan
Sol 1586’s plan called for the rover’s Right Mastcam to acquire small mosaics of nearby rocks named “Bell Brook,” “Blind Brook,” and “Beck Pond,” then Left Mastcam is slated to take another image of the rover deck to look for changes in the dust and sand on the deck.

The rover was scheduled to rest until late that afternoon, when the illumination will be good for Mars Hand Lens Imager (MAHLI) photo taking.
MAHLI is to take a single image before the Dust Removal Tool (DRT) is used to brush off a bedrock target dubbed “Belle Lake,” then take a full suite of images (plus extra stereo images) of the brushed spot.
MAHLI is to also acquire a full suite of images of another bedrock target called “Bluffer Pond” before the Alpha Particle X-Ray Spectrometer (APXS) to be placed on the same target for a short integration.
Just before midnight, the APXS is to be placed on Belle Lake for a longer integration.
Multispectral set of images
Herkenhoff adds that on Sol 1587, the arm will be retracted and stowed to allow Mastcam to acquire a full multispectral set of images of Belle Lake.

Navcam is to search for dust devils before the next drive. In addition to the standard post-drive activities, the arm will be unstowed to allow Navcam to take stereo images of the new arm workspace.
Curiosity’s Mars Descent Imager (MARDI) is slated to take images during twilight on Sols 1587 and 1588 to look for any changes due to winds.
Navcam is scheduled to again search for dust devils on Sol 1588, and the robot’s Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) is on tap to perform some maintenance activities overnight.

Straight line distance
In a map release of January 19, Curiosity’s Location for Sol 1584 shows that the robot has driven a straight line distance of about 101.10 feet (30.82 meters) from Sol 1583 to Sol 1584.
Since touching down in Bradbury Landing in August 2012, Curiosity has driven 9.48 miles (15.26 kilometers) as of Sol 1584.

Moonshine – space exploration style!
A team of University of California San Diego (UCSD) engineering students is in ferment – all hopped up to see if beer can be brewed on the Moon.
Their experiment is designed to test the viability of yeast on the Moon. The brewmasters stem from UCSD’s Jacobs School of Engineering calling themselves “Team Original Gravity.”
They are one of 25 teams selected from a pool of several thousand entries to compete for a spot aboard a moonbound lander/rover planned for launch on Dec. 28, 2017.
TeamIndus
The spacecraft is owned by the Indian startup TeamIndus, an industrious Indian group competing for the Google Lunar XPRIZE and a $30 million purse. To win, a privately funded team must successfully place a robot on the Moon that explores at least 1,640 feet (500 meters) and transmits high-definition video and images back to Earth.

TeamIndus has secured a launch contract from the Indian Space Research Organization (ISRO) for a booster flight.
TeamIndus invited experiment ideas from researchers under 25 years of age to imagine, design and build an experiment that will help humankind build sustainable life on the Moon.
Shortlisted experiments
In Phase-I of the “Lab2Moon” challenge, participants were asked to send in a concept note and video of their idea. That generated 3,000 entries from 15 countries and 300+ cities across the globe.
The competition then entered Phase-II in which 25 teams were shortlisted to build prototypes of their concept to showcase to an international jury of experts in March at the finals in Bangalore. Teams from India, Peru, Mexico, USA, UK, Spain and Italy made it to the list.
Other proposed experiment ideas include: radiation shielding using bacteria; effect on plant growth in lunar regolith; lunar sintering of lunar soil; inflatable dome testing; as well as a lunar gene bank for endangered species.

ALEiens!
In a UCSD press statement, Neeki Ashari, a fifth year bioengineering student at UC San Diego and the team’s PR & Operations Lead: “We all appreciate the craft of beer, and some of us own our own home-brewing kits. When we heard that there was an opportunity to design an experiment that would go up on India’s moonlander, we thought we could combine our hobby with the competition by focusing on the viability of yeast in outer space.”

Understanding how yeast behaves on the Moon to brewing beer in space is just one application. It’s also important for the development of pharmaceuticals and yeast-containing foods, like bread, Team Original Gravity points out. “The symbiotic relationship between humans and yeast would no doubt be vital for future colonization of the Moon and other planets.”

Observers on Earth have imaged both the International Space Station as well as China’s now un-crewed Tiangong-2 space lab.
The ISS outpost is the largest structure in orbit, spanning the size of a football pitch, but at 400 km altitude it still appears tiny through a telescope.
Sequence of images
Michel Breitfellner, Manuel Castillo, Abel de Burgos and Miguel Perez Ayucar work at the European Space Agency’s (ESA) European Space Astronomy Center and are members of its astronomy club.
The sky watchers braved freezing temperatures to set up two telescopes with reflex cameras to record a sequence of images as the ISS crossed the face of the Moon.
As the Station could be seen only when in front of the Moon, the group had to press the shutter and hope for the best. “Their calculations were perfect and the result speaks for itself,” notes an ESA statement on the astrophotography.

China’s space lab
Meanwhile, satellite sleuth Mariano Ribas from Buenos Aires, Argentina has also released some new imagery of the ISS, as well as China’s Tinagong-2 space lab.
The Chinese space lab was visited late last year by the two-person Shenzhou-11 crew: Jing Haipeng, crew commander and a third-time space traveler, and Chen Dong, a first-time space traveler.

The two astronauts lived for 30 days onboard Tiangong-2 before returning to Earth – the longest time Chinese astronauts have spent in space and a prelude to that country’s building of a permanent space station in the 2020s.
Cargo spacecraft
In related news from China, the Xinhua news agency has reported that the country’s first cargo spacecraft – the Tianzhou-1 — is set leave its factory site. The Tianzhou-1 cargo spacecraft has met all the requirements to leave the factory, Xinhua has noted.
The take-off weight of Tianzhou-1 is 13 tons and can contain up to 6 tons of material for docking with the Tiangong-2.

That automated spacecraft is to be launched in April from the southern province of Hainan, then dock with the Tiangong-2 space lab and refuel the facility.
Doing so will signal an important step for China in building a space station in the 2020s. These cargo ships are required to transfer necessities from Earth for astronauts aboard the space station.

Two NASA rovers are busily working on the Red Planet – Opportunity and the Curiosity robots.
“Opportunity is mainly traversing uphill to the southwest on Cape Tribulation, trying to get back to the Meridiani Plains to head south to Cape Byron and the top of a gully system before the end of the southern summer.”
That’s the word from Ray Arvidson of Washington University in Saint Louis. He is deputy principal investigator of the rover mission.

Steady progress
Opportunity’s health is steady, Arvidson told Inside Outer Space, although climbing 15 to 20 degree slopes is difficult, he said.
“But steady progress is being made. We are characterizing the Shoemaker formation impact breccia outcrops along the climb uphill,” Arvidson said.
The robot airbag bounced to full stop in Meridiani Planum on January 25, 2004.
As of Sol 4609 (Jan. 10, 2017), the rover’s total odometry was 27.20 miles (43.77 kilometers).

Frost Pond
Elsewhere on Mars, the Curiosity rover is also at work, performing Sol 1584 duties.
On Sol 1583 Curiosity drove 52 feet (16 meters), a trek that set up touch-and-go contact science.
As scripted, the plan for the Mars robot is to start with a short Alpha Particle X-Ray Spectrometer (APXS) integration on the target “Frost Pond.”

The intent is to investigate the chemistry of a typical Murray bedrock block, reports Lauren Edgar, a research geologist at the USGS Astrogeology Science Center in Flagstaff, Arizona. Then the plan calls for a full suite of Mars Hand Lens Imager (MAHLI) images to be taken on the same target.
Search for dust devils
Later in the plan is acquiring a Chemistry& Camera (ChemCam) observation of “Frost Pond” for comparison, and also taking a Mastcam image for documentation.

“We’ll also acquire a small Mastcam mosaic of “Burnt Brook” to investigate some color variations and a Navcam observation to search for dust devils,” Edgar adds.

“After another drive, we’ll take post-drive imaging for targeting. Later in the afternoon we’ll use Mastcam to monitor the movement of fines on the rover deck and take a systematic clast survey,” and ChemCam will take another Autonomous Exploration for Gathering Increased Science (AEGIS) observation, Edgar concludes.
Dates of planned rover activities are subject to change due to a variety of factors related to the Martian environment, communication relays and rover status.

NASA’s Curiosity rover has indeed found another iron-nickel meteorite, now called “Ames Knob,” on the surface of the Red Planet.
As reported earlier on Inside Outer Space, the object spotted by the robot is mostly iron, some 90 percent iron with a small amount of nickel, says Roger Wiens, Curiosity’s Chemistry & Camera (ChemCam) principal investigator for the Mars Science Laboratory rover effort at Los Alamos National Laboratory in New Mexico.
Laser shots
“Yes, indeed, we did a brief compositional analysis of Ames Knob with ChemCam, with just three laser locations,” Wiens told Inside Outer Space.

In October 2016 the rover found a similar iron-nickel meteorite dubbed “Egg Rock.”
Wiens said: “While one observation point of Egg Rock showed the presence of phosphorous, we did not observe any of this element in Ames Knob. It is still likely that Ames Knob is the same meteorite type and may have fallen at the same time as Egg Rock.”
4th find by Curiosity
Ames Knob is approximately 4 x 6 inches in size (10 x 14 centimeters), Wiens adds. “On Earth it would weigh about 0.8 kg or a little less than 2 pounds. We observed it from about 10-feet (3.4 meters) distance.”
It is the 4th meteorite to be found by the Curiosity rover, Wiens pointed out.
The third one, Egg Rock, was found and analyzed by ChemCam on sol 1505. It was somewhat smaller, at about 5 cm diameter. The first two meteorites, Lebanon and Littleton, were both quite large, at over 1 meter in length, and were imaged around sol 634, a little less than 5 kilometers [3 miles] from where the rover is now, Wiens pointed out.
October 30, 2016 image taken by Curiosity on Sol 1505. This iron-nickel meteorite was dubbed “Egg Rock.”
Falling on land…or water?
“All of these are iron meteorites,” Wiens notes, “are relatively easy to distinguish from the Mars rocks.”
The pre-Curiosity Mars Exploration Rover (MER) – Spirit and Opportunity — also found several meteorites on Mars.
“We hope that meteorites will be able to tell us some information about the Mars environment, such as whether they fell on land or in water, or how dense the atmosphere was when they fell,” Wiens explains.
