A new traverse map through Sol 1785 has been issued showing the robot’s drive and current location.

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 1782 to Sol 1785, Curiosity had driven a straight line distance of about 99.05 feet (30.19 meters), bringing the rover’s total odometry for the mission to 10.62 miles (17.09 kilometers).

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

Astrobotic and United Launch Alliance (ULA) released today an end to end mission video for Astrobotic’s projected flight to the Moon during the 50th anniversary of Apollo 11 in 2019.

Astrobotic Technology Inc. is a lunar logistics company that delivers payloads to the Moon for companies, governments, universities, non-profits, and individuals.

The Peregrine Lunar Lander is designed to fly 35 kilograms of customer payloads on its first mission, with the option to upgrade to 265 kilograms on future missions.

According to Astrobotic 11 deals from six nations have already been signed for the 2019 mission.

The first mission in 2019 will serve as a key demonstration of service for NASA, international space agencies, and companies looking to carry out missions to the Moon.

One of the largest of the near-Earth asteroids, will approach close to Earth at the end of August, and will shoot safely by our world on September 1.

“Although many known asteroids have passed by closer than this, all of them were smaller asteroids. Florence is the largest asteroid to pass this close to our planet since the first near-Earth asteroid was discovered over a century ago,” explains JPL’s Paul Chodas, manager of the Center for NEO Studies (CNEOS).

Detailed measurements

At its closest point, Florence will be 4.4 million miles (7.0 million kilometers) from Earth, or about 18 times the average Earth-Moon distance.

“The September 1 flyby of Florence will provide astronomers with an excellent opportunity to make detailed measurements of a large near-Earth asteroid,” Chodas adds. “In particular, radar scientists expect to obtain high-resolution images of Florence that could reveal surface features as small as about 10 meters (30 feet).”

Chodas says that infrared measurements from NASA’s Spitzer Space Telescope and the NEOWISE spacecraft indicate that Florence is roughly 2.7 miles (4.3 kilometers) in size, and measurements of its brightness variations indicate that it rotates once every 2.36 hours.

Easily visible

“As it approaches in late August and early September, it is expected to brighten to 9th magnitude, making it easily visible, even using a small telescope,” Chodas notes.

Asteroid Florence was discovered in 1981 and named in honor of Florence Nightingale (1820-1910), the founder of modern nursing.

Tracking observations of asteroid Florence span nearly 40 years and its orbit is already well known.

“The orbital calculations indicate,” Chodas concludes, “that asteroid Florence poses no risk of colliding with Earth for many centuries to come.”

NASA commercial cargo provider SpaceX is targeting its 12th commercial resupply services mission to the International Space Station early next week.

Loaded with more than 6,400 pounds of research, crew supplies and hardware, the SpaceX Dragon spacecraft will launch on a Falcon 9 rocket.

The payloads include crucial materials to directly support several of the more than 250 science and research investigations to be conducted on the orbiting laboratory during Expeditions 52 and 53.

Spaceborne computer

Onboard the SpaceX Dragon is a year-long experiment, a team effort of Hewlett Packard Enterprise and NASA. That length of time will test a supercomputer’s ability to function in the harsh conditions of space.

From faster problem solving to astronaut survival, Hewlett Packard Enterprise’s (HPE) Spaceborne Computer is the first step in developing sophisticated onboard computing resources.

Mars mission

The Spaceborne Computer is part of a year-long experiment conducted by HPE and NASA to run a high performance commercial off-the-shelf (COTS) computer system in space, which has never been done before. The goal is for the system to operate seamlessly in the harsh conditions of space for one year – roughly the amount of time it will take to travel to Mars.

“We see the Spaceborne Computer experiment as a fitting extension to our HPE Apollo portfolio, purpose-built for supercomputing. HPE is excited to expand its relationship with NASA, pioneering HPC in space and taking one step closer to a mission to Mars,” explains Alain Andreoli, a senior vice president and general manager of HPE’s Data Center Infrastructure Group.

Memory-driven computing

According to Kirk Bresniker, chief architect of Hewlett Packard Labs, the mission to Mars will require the most powerful computing system the world has ever seen, “but the incremental increases we are seeing in our computing power will not meet the exponential demands of our future challenges.”

To that end, the 21st century computer to solve 21st century problems is HPE’s Memory-Driven Computing.

The Spaceborne Computer includes the HPE Apollo 40 class systems with a high speed HPC interconnect running an open-source Linux operating system. A unique water-cooled enclosure for the hardware has been designed. Also purpose-built system software addresses the environmental constraints and reliability requirements of supercomputing in space, according to HPE.

In order for NASA to approve computers for space, the equipment needs to be hardened to withstand the conditions in space: radiation, solar flares, subatomic particles, micrometeoroids, unstable electrical power, irregular cooling.

Different approach

Physical hardening of a computer takes time, money and adds weight.

HPE took a different approach to “harden” the systems with software. HPE’s system software will manage real-time throttling of the computer system based on current conditions and can mitigate environmentally induced errors.

During high radiation events, the electrical power consumption and, therefore, the operating speeds of the computer systems are lowered in an attempt to determine if such systems can still operate correctly.

“Even without traditional ruggedizing, the system still passed at least 146 safety tests and certifications in order to be NASA-approved for space,” according to HPE.

Yottabytes

Given how the Spaceborne Computer reacts in space, future phases of this experiment will eventually involve sending other new technologies and advanced computing systems, like HPE’s Memory-Driven Computing, to the International Space Station.

HPE’s engineering eye is focused on Memory-Driven Computers with up to 4,096 “yottabytes” of data. That’s more than 250,000 times the size of our digital universe today.

The unit symbol for the yottabyte is YB. One YB = 10008bytes = 1024bytes = 1000000000000000000000000bytes = 1000zettabytes = 1trillionterabytes.

The Colorado School of Mines is establishing a multi-disciplinary graduate program in space resources.

“We have launched a new, first-of-its-kind program at Mines on Space Resources,” said Angel Abbud-Madrid, Director of the Center for Space Resources at the Colorado School of Mines in Golden, Colorado.

The proposed program will focus on developing core knowledge and gaining design practices in systems for responsible exploration, extraction, and use of resources in the Solar System.

“The program will be fully implemented next year, but we are already offering classes this coming semester,” Abbud-Madrid told Inside Outer Space.

Leading institution

Since the 1990s, the School of Mines in Golden, Colorado has been a leading institution for the study of space resources and in situ resource utilization (ISRU). It has also become a destination for space scientists and engineers, government agencies, aerospace companies, entrepreneurs, the mining and minerals industry, financial and legal experts, and policy makers to discuss all topics related to space resources.

Abbud-Madrid notes that in recent years, growing interest in ISRU by space agencies and the private sector has been driven by an awareness that further development of space travel will be enabled through extraction of materials and production of propellants in space for more affordable and flexible transportation, facilities construction, and life support.

Many fields

The broad topic of space resources brings together many fields, Abbud-Madrid adds, in which Mines has a strong presence, including remote sensing, geomechanics, mining, materials/metallurgy, robotics/automation, advanced manufacturing, electrochemistry, solar and nuclear energy, and resource economics.

In anticipation of the new space resources program, this Fall 2017 the School of Mines will start offering a course entitled Space Resources Fundamentals (with synchronous distance-learning options available).

This activity will be followed in the Spring by a space systems engineering course, a design project class, and a seminar series – all with a space resources focus.

NASA’s Curiosity Mars rover is now wrapping up Sol 1782 science duties.

Rachel Kronyak, a planetary geologist at the University of Tennessee in Knoxville, reports that the robot is busily taking measurements as it climbs Mount Sharp.

Up Mount Sharp

“Lately, one of our biggest science objectives is to conduct bedrock [Alpha Particle X-Ray Spectrometer] APXS measurements with every 5-meter climb in elevation,” Kronyak notes. “This allows us to systematically analyze geochemical changes in the Murray formation as we continue to climb Mount Sharp.”

For example, a recent drive by Curiosity brought it 20 feet (6 meters) higher in elevation, so another “touch and go” was orchestrated.

Slopes of Vera Rubin Ridge

On tap is analyzing the Murray target “Thorne” with APXS and the rover’s Mars Hand Lens Imager (MAHLI), followed by a short Chemistry & Camera (ChemCam) observation on the same target.

“We’ll also take several additional Mastcam images of ‘Devilled Rocks’ and ‘Butter’ which will document blocks on the slopes of the Vera Rubin Ridge (VRR),” Kronyak adds.

Following the robot’s “touch” activities, the plan is to “go” and complete another  drive.

Weekend plan

“To set ourselves up for a nice weekend plan, we’ll take some post-drive images,” Kronyak explains.

Standard Rover Environmental Monitoring Station (REMS) and Dynamic Albedo of Neutrons (DAN) blocks of time are to be carried out.

“We should be arriving at our next VRR imaging stop after today’s drive,” Kronyak concludes, “so stay tuned for exciting Mastcam mosaics that we’ll be acquiring over the weekend!”

Clouds on the horizon

Meanwhile, JPL has issued an interesting view of clouds drifting across the sky above a Martian horizon.

Boeing is pressing ahead on scoping out its deep space gateway and transport systems plans.

A recent Future In-Space Operations (FISO) seminar hosted Boeing’s Matt Duggan who spoke on: “Next Steps in Human Exploration: Cislunar Systems and Architectures.” He is the Boeing Manager for Exploration Integration and leads Boeing’s advanced  development projects on extending human presence to cislunar space and Mars.

NASA’s Space Launch System (SLS), which Boeing is helping develop, would deliver the habitat to cislunar space near the Moon. Known as the Deep Space Gateway, the habitat could support critical research and help open opportunities for global government or commercial partnerships in deep space, including lunar missions. It would be powered by a Solar Electric Propulsion (SEP) system.

Waypoint for Mars

The Deep Space Gateway could be the waypoint for Mars missions. A Mars spaceship habitat, in fact, might be developed from SLS propellant tank structure.

Utilizing a docking system akin to what the International Space Station uses for commercial operations, it could host the Deep Space Transport vehicle, which would take humans to Mars.

Once near Mars, crews could deploy a lander for surface missions or conduct other scientific and robotic missions in orbit – perhaps land on Phobos, one of the two moons of Mars.

The gateway and transport systems are partially being developed as part of NASA’s Next Space Technologies for Exploration Technologies (Next Step) program and an ongoing High Power SEP technology development effort within the NASA Space Technology Mission Directorate (STMD).
