NASA’s Curiosity Mars rover is now performing Sol 2502 duties.
The Mars machinery is headed for a conjunction, a few-week period when Mars goes behind the Sun and ground controllers stop communicating with spacecraft that are there.
“Our last planning day before conjunction will be next Friday and thinking about that fast approaching day feels very similar to thinking about getting ready to leave for vacation,” reports Abigail Fraeman, a planetary geologist at NASA’s Jet Propulsion Laboratory.
“The Curiosity science team has many things we want to wrap up before conjunction,” Fraeman adds, “so we’re trying to work extra hard to do as much as we can before setting up Curiosity’s (figurative) auto-reply ‘I’m behind the sun’ email.”
Analyses of drill sample
The recent weekend plan was all about running additional Sample Analysis at Mars (SAM) Instrument Suite analyses on the Glen Etive drill sample.
The plan called for delivery of a portion of the drill sample to SAM on lucky sol 2500, Fraeman notes, and SAM was to analyze its composition using the gas chromatograph and mass spectrometer (GC-MS) on sol 2501.
“This SAM activity is preceded by an activity to clean the GC column on sol 2499, and the combined observations use so much power, there’s not a lot left for other activities,” Fraeman explains.

Some remote sensing
Mars researchers did manage to fit in a little bit of remote sensing, taking two Chemistry and Camera (ChemCam) targets of “Sutherland” and “Risk” with their associated Mastcam images, along with some images to monitor dust in the atmosphere.
Fraeman concludes by pointing out that scientists are looking forward to seeing the results from the SAM run.
India is celebrating the Lunar Orbit Insertion (LOI) of the country’s Chandrayaan-2 spacecraft.
“The LOI maneuver was performed successfully today morning using the onboard propulsion system for a firing duration of about 29 minutes,” said Dr. K Sivan, Chairman, Indian Space Research Organization (ISRO), in an August 20 press briefing.
“This maneuver precisely injected Chandrayaan-2 into an orbit around the Moon,” Sivan added. He emphasized the unique requirement of 90 degree orbital inclination of Chandrayaan-2 and said that it was achieved by the precise execution of both the Trans Lunar Injection (performed on August 14, 2019) and today’s LOI maneuver.
Next milestones
India’s Moon mission – an orbiter, lander and rover — is now located in a lunar orbit with a distance of about 70 miles (114 kilometers) at perilune (nearest point to the Moon) and 11,300 miles (18,072 kilometers) at apolune (farthest point to the Moon.
Early next month, a series of four orbit maneuvers will be performed on Chandrayaan-2 spacecraft to enable it to enter its final orbit passing over the lunar poles at a distance of about 60 miles (100 kilometers) from the Moon’s surface.
Lander release
Subsequently, on September 02, 2019 the Vikram lander will separate from the Moon-circling orbiter.
Following this, orbit maneuvers will be performed on Vikram to place it in a 60 x 19 mile (100 x 30 kilometer) orbit around the Moon.
The Vikram lander will then perform a series of complex braking maneuvers to soft land in the South polar region of the Moon between two craters, Manzinus C and Simpelius N on September 7, 2019.
All systems healthy
A few hours following touchdown, the Pragyaan rover will roll down from Vikram and will perform on-the-spot exploration of the surrounding lunar surface.
The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru.
All the systems of Chandrayaan-2 are healthy, reports ISRO.

It is called Great Lunar Expedition for Everyone (GLEE) – hundreds of tiny circuit boards to carry out local and distributed science missions on the Moon.
The concept stems from team work at Cornell University that developed a tiny spacecraft called ChipSat, a way to radically reduce the costs of spaceflight and exploration in low Earth orbit.
LunaSats are based on the ChipSat design. The leaf-sized LunaSats are the brainchild of Mason Peck, a professor at Cornell University.
Each LunaSat – weighing approximately 5 grams — will work as a fully-capable spacecraft, an electronic board outfitted with a small solar panel, several environmental sensors, and a radio for communicating with other LunaSats and relaying data gathered back to Earth.
LunaSats, for example, can gather temperature, GPS, magnetometer, humidity and accelerometer measurements. Their mission on the Moon will last two lunar days or approximately 56 Earth days.
GLEE goal
The GLEE goal: By December 14, 2022, 500 LunaSats, built by students from every nation on Earth, will land on the Moon to conduct multiple distributed science and technology missions.
The GLEE space mission is led by NASA’s New York and Colorado Space Grant Consortium. Peck is director of the New York Space Grant Consortium. More than 20 other space grant organizations have also signed onto GLEE.
The space grant consortium is funded by NASA’s Office of STEM Engagement under the National Space Grant College and Fellowship Program.

Moon dispersal plan
Each LunaSat is projected to cost less than $200, explains Chris Koehler, director of the Colorado Space Grant Consortium, which is based at CU Boulder.
Groups of high school and college students can apply to get involved in GLEE starting early December of this year. Participation will be free for all teams. Koehler and other “GLEEmers” are seeking out supporters from universities and private companies around the world.
Koehler told Inside Outer Space that there is no confirmed launcher as yet. “We hope to share a ride to the surface. We understand that we likely will have to pay for the ride,” he explained.
As now envisioned, the plan is to deploy the LunaSats from a lander firmly planted on the lunar terrain. “Using a simple device, the LunaSats would be spread out roughly 65 to 130 feet (20-40 meters) around the landing site,” Koehler notes.
Team building
Individual LunaSats carry an integrated sensor suite that can be programmed by teams of students, from every member country of the United Nations, to a mission of their own design.
These teams will be mentored by GLEE program staff through the entire design, build, test, launch, and data gathering process.
Koehler underscores part of the GLEE mission statement: “From hands-on activities to a global citizen science network, GLEE is the next step in inspiring and engaging the world in a truly global mission to the Moon.”

China Central Television (CCTV) reports:
China’s new carrier rocket Smart Dragon-1 (SD-1), designed for commercial use, made its maiden flight on Saturday, sending three satellites into the orbit.
The rocket, developed by the China Rocket Co. Ltd. affiliated to the China Academy of Launch Vehicle Technology (CALVT), blasted off from the Jiuquan Satellite Launch Center in northwest China at 12:11 (Beijing Time).
Vital internal organs
It is the smallest and lightest among China’s solid rockets. It is 19.5 meters long with a diameter of 1.2 meters and a takeoff weight of 23.1 tons.
“The rocket is small, but it has all the vital internal organs and a carrying capacity not small at all. It can carry 200 kilograms to the Sun-synchronous orbit 500 kilometers away from the Earth. So in terms of carrying efficiency, it is the highest in our solid carrier rockets,” said Gong Min, technical manager of the SD-1 project.

Short launch preparation
Another advantage of the rocket is the short launch preparation. According to the company, it can be turned in [made available] six months after a contract is signed, and launched within 24 hours after it is transported to the launch center.
“We plan to make another launch at the end of this year in the Jiuquan center. Next year, we are going to make perhaps five launches. All the six launches have been booked by clients,” said Tang Yagang, President of the China Rocket Co. Ltd.
This time the rocket carried three commercial satellites which are to do remote sensing, telecommunication and navigation.

NASA’s Curiosity Mars rover is now performing Sol 2497 tasks.
Curiosity is go for analyzing a new drill sample, reports Ashley Stroupe, a mission operations engineer at NASA’s Jet Propulsion Laboratory in Pasadena, California.
After seeing that the redo of the Sample Analysis at Mars (SAM) Instrument Suite preconditioning in Monday’s plan was successful, the SAM team was ready to drop-off four portions to SAM for evolved gas analysis.
Targeted science
“The power demands of SAM left little room for other activities on the first sol of the plan, but we were able to fit in some additional science on the second sol,” Stroupe adds.
In the afternoon of sol 2498, the plan called for the robot to do targeted science, including Mastcam and Chemistry and Camera (ChemCam), of the targets “Liberton” and “Torberg” to get the chemistry of the other plates near the drill target.
Additional analysis
“There are also some standard environmental observations, such as Mastcam tau and crater rim extinction imaging and Navcam imaging to search for dust devils clouds,” Stroupe notes.

Also planned was obtaining another data readout from the Chemistry & Mineralogy X-Ray Diffraction/X-Ray Fluorescence Instrument (CheMin) on the sample dropped off on Monday.
“The results of the SAM analysis will be available prior to planning on Friday, and based on those results, the SAM team will determine whether to do additional analysis on the Glen Etive drill sample in the weekend plan,” Stroupe adds.
China is offering space experiment “room and board” on the country’s future space station, as well as upcoming Moon, asteroid and comet explorers.
In early June, the China Manned Space Agency announced the first batch of nine international cooperation projects for the country’s space station involves 23 entities from 17 countries.
The deadline for new station proposals is August 31st.
Rack space
Domestically, research institutions, universities, science and technology enterprises, and even the public are welcome to suggest experiments to be conducted on the Chinese space station through an online portal.
Sixteen experiment racks are to be installed in the core module of the space station, and two lab capsules of the space station and an extravehicular experiment platform.
Each rack is regarded as a lab that can support various space experiments, and astronauts can upgrade and replace the facilities. In addition, a capsule holding a large optical telescope will fly in the same orbit as the Chinese station, according to a report by Xinhua News Agency, quoting the Technology and Engineering Center for Space Utilization of the Chinese Academy of Sciences.

Lunar exploration
In related China space news, an August 31st deadline has been set for proposals to fly on the Chang’e-6 lunar sample return mission.
Chang’e-6’s launch time and landing site will depend on the status of the upcoming Chang’e-5 lunar sample and return to Earth mission.
The orbiter and the lander will each provide 22 pounds (10 kilograms), with a total of 44 pounds (20 kilograms) for scientific payloads onboard.
Asteroid, comet studies
Also available for ride-along experiments is a Chinese sample return mission to Asteroid 2016HO3 and the orbiting of a main-belt comet.
Following Earth return of the asteroid samples, the Chinese probe will make a gravity assist of Earth and Mars, and arrive at the asteroid belt and orbit the Comet 133P. Comet 133P/(7986) Elst–Pizarro is a body that displays characteristics of both an asteroid and a comet.
The entire mission will last roughly 10 Earth years.
The deadline for scheme proposals for Chang’e-6 and the asteroid mission is August 31, 2019.

If you have your eyes on the Moon and making money on water mining operations, a new analysis concludes the current market is over $200 billion.
The new market study has looked at the need for water in space over the next three decades.
Producing water on the Moon is considered to be viable and the assessment suggests that “the first company to exploit this identified demand will likely reap extraordinary profits.”

Attractive rates
The appraisal — Conceptual Economic Lunar Water Mining — comes from Watts, Griffis and McOuat Limited (WGM), based in Toronto, Canada.
WGM has concluded the current market is over $200 billion and that a viable water mining operation on the Moon could produce water at economically attractive rates.
Fundamental questions
According to WGM, the purpose of the study was to answer some fundamental questions regarding the viability of space water mining operations:
- Is there a potential future market for water in space?
- What is the expected market price for water in space?
- Is it technically feasible to produce water in space and at what cost?
“Based on our research, the answer is yes to all these questions,” WGM explains, but adds: “We should note our work is a first-order estimate and is not definitive, as the market is evolving rapidly.”
No assurances
While bullish on lunar water prospects, WGM explains that its analysis is of a conceptual nature and there are “no assurances” that the group’s demand estimates are correct and cautions readers that there is a very high level of variance likely.

That said, WGM’s analysis of the space-based water market shows both economic and technical potential to create a space-based mining operation.
“Although our analysis does not conform to terrestrial standards for technical reporting, we have attempted to employ similar methodologies in creating our model. WGM trusts our work will assist future efforts to open up new ventures in space.”
Market demand
In spotlighting the market demand, the study includes looks at satellite refueling, International Space Station demand, as well as a lunar gateway space station, even space tourism and hotels.
The report recommends that additional engineering work be carried out by governments, academic groups and private enterprise to solve some of the technical challenges they have identified.
“We also challenge Earth’s entrepreneurs and financiers to consider how to finance and launch commercial ventures to take advantage of these markets. By doing so, WGM believes the colonization of space by humankind will be achievable in the not-too-distant future,” the study explains.

The Chandrayaan-2 lunar orbiter/lander/rover mission has successfully entered Lunar Transfer Trajectory.
The final orbit raising maneuver of the Chandrayaan-2 spacecraft was carried out August 14, 2019 at 02:21 am IST.
During this maneuver, the spacecraft’s liquid engine was fired for about 1,203 seconds. With this burn, Chandrayaan-2 entered the Lunar Transfer Trajectory.
Spacecraft health
Earlier, the spacecraft’s orbit was progressively increased five times during July 23 to August 6, 2019.
The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at the Indian Space Research Organization’s (ISRO) Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Byalalu, near Bengaluru.
Since its launch on July 22, 2019 by a GSLV MkIII-M1 launcher, all systems onboard Chandrayaan-2 spacecraft are performing normally, reports ISRO.
Lunar orbit
Chandrayaan-2 will approach the Moon on August 20, 2019 and the spacecraft’s liquid engine will be fired again to insert the spacecraft into a lunar orbit.

Following this, there will be further four orbit maneuvers to have the spacecraft enter into its final orbit passing over the lunar poles at a distance of about (62 miles (100 kilometers) from the Moon’s surface.
A tentative plan for future operation after Trans Lunar Injection has the spacecraft placed in a roughly 71 x 80 mile (114 x 128 kilometer) orbit at the Moon.
Subsequently, the mission’s Vikram lander will separate from the orbiter on September 2, 2019. Two orbit maneuvers will be performed on the lander before the initiation of a powered descent to make a soft landing on the lunar surface on September 7, 2019, touching down near the Moon’s south pole.
