Reports Roger Wiens, a geochemist at the Los Alamos National Laboratory in New Mexico: That spot has been subdivided into separate nearby sites, with the current one as B1, still near the edge of the hematite “hotspot” identified from orbit by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument on the Mars Reconnaissance Orbiter.
Float rocks
“Curiosity is flirting with the boundary of the mapped “Biwabik” quadrangle; pretty soon we will drive into it for a while and start using target names from northern Minnesota,” Wiens points out. “The Biwabik name was selected because of the city’s connection with the Mesabi Range, which contains large deposits of Precambrian iron ore.”

The rover is back into the “Torridon” quad with Scottish names, a quad that Curiosity has been exploring most of the sols in the last several weeks. “The team is intrigued to see some fields of dark, blocky float rocks nearby,” Wiens adds.
Science duties
Curiosity’s planned science duties include Chemistry and Camera (ChemCam), Mastcam, Mars Hand Lens Imager (MAHLI), and Alpha Particle X-Ray Spectrometer (APXS) observations on “Lingarabay” and “Kinloch”.

The robot’s Dust Removal Tool will be used on the first of the two targets, which will be an overnight APXS target.
MAHLI’s observation distances will be 25 centimeters and 5 centimeters. Mastcam’s right-side camera will stay busy, with a 5×1 mosaic on the “hematite hotspot”, a 2×1 on “Galloway”, a 5×1 on “Foula”, a 5×1 on “Suilven” (targeting grain sizes along a ripple crest) and a single image on “Arrochar.”
Additional measurements, Wiens adds, include Dynamic Albedo of Neutrons (DAN) passive, Rover Environmental Monitoring Station (REMS) and Radiation Assessment Detector (RAD) acquisitions, Mastcam sun tau measurement, crater rim extinction, and calibration target observations as well as the rover making a drive direction 4×1 observation.

Robot inhabitants
Wiens provided some interesting factoids: “Mars is the only known planet inhabited exclusively by active robots. It has been this way for over fourteen Earth years, with a cumulative total of twenty-six Earth years of roving by four vehicles. Together these rovers have logged over 70 kilometers of distance, well over half of that by the Opportunity rover. (Curiosity will likely hit the 20 kilometer mark later this year).

Updated traverse map
A new Curiosity’s traverse map through Sol 2012 has been issued.
The map shows the route driven by NASA’s Mars rover Curiosity through the 2012 Martian day, or sol, of the rover’s mission on Mars (April 04, 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 2009 to Sol 2012, Curiosity had driven a straight line distance of about 66.38 feet (20.23 meters), bringing the rover’s total odometry for the mission to 11.59 miles (18.65 kilometers).

Clean release
VSS Unity took off this morning into clear Mojave skies at 8:02 am with Mark “Forger” Stucky and Dave Mackay in the cockpit, attached to the WhiteKnightTwo carrier aircraft, VMS Eve, piloted today by Mike Masucci and Nicola Pecile.
“The mated vehicles climbed to a launch altitude of around 46,500 feet over the Sierra Nevada Mountains and while pointing back at Mojave, Eve executed a clean release of Unity,” Virgin Galactic noted in a press statement.
“After a few seconds, Unity’s rocket motor was brought to life and the pilots aimed the spaceship upwards into an 80 degree climb, accelerating to Mach 1.87 during the 30 seconds of rocket burn. The hybrid (nitrous oxide / HTPB compound) rocket motor, which was designed, built and tested by The Spaceship Company, powered Unity today through the transonic range and into supersonic flight for the first time.”
Virgin Spaceship Unity is unveiled in Mojave, California February 19th, 2016. VSS Unity is the first vehicle to be manufactured by The Spaceship Company, Virgin Galactic’s wholly owned manufacturing arm, and is the second vehicle of its design ever constructed. VSS Unity was unveiled in FAITH (Final Assembly Integration Test Hangar), the Mojave-based home of manufacturing and testing for Virgin Galactic’s human space flight program.

Feathered flight
On rocket shutdown, Unity continued an upwards coast to an apogee of 84,271 feet before readying for the downhill return.
At that point the SpaceShipTwo pilots raised the vehicle’s tail booms to a 60 degree angle to the fuselage, into the “feathered” configuration. “This unique design feature, which is key to a reliable and repeatable re-entry capability for a winged vehicle, incorporates the additional safety mechanisms adopted after the 2014 VSS Enterprise test flight accident,” Virgin Galactic reports. That powered flight led to a destructive breakup of the vehicle, killing one of the two pilots on Oct. 31, 2014.

At around 50,000 feet, the tail-booms were lowered again and, while jettisoning the remaining oxidizer, Unity turned towards Mojave for the glide home and a smooth runway landing.
Explains Virgin Galactic: “The flight has generated valuable data on flight, motor and vehicle performance which our engineers will be reviewing.”
Today’s flight also marks a key moment for the test flight program, entering now the phase of powered flight and the expansion to full duration rocket burns.

A recent NASA Innovative Advanced Concepts (NIAC) award is focused on letting loose on Mars a swarm of flapping flyers.
“Flying on Mars is challenging because of the ultra-low density in the Martian atmosphere. Our preliminary work shows that bioinspired aerodynamic mechanisms can help in generating sufficient lift to fly on Mars,” explains Chang-kwon Kang, an assistant professor of mechanical and aerospace engineering at The University of Alabama in Huntsville (UAH).
UAH researchers will numerically model, analyze, and optimize a flapping flyer for Martian atmospheric conditions. They will work in tandem with Japanese colleagues that will develop and test a micro-flapping robot that is uniquely designed and constructed for the low-density atmosphere on Mars.
Flapping wing flyers
Kang’s winning NIAC proposal, entitled “Marsbee – Swarm of Flapping Wing Flyers for Enhanced Mars Exploration,” seeks to increase the set of possible exploration and science missions on Mars by investigating the feasibility of flapping-wing aerospace architectures in a Martian environment.

At its center is the Marsbee, a robotic bumble-bee-sized flapping-wing flyer whose large cicada-like wings have the ability to generate sufficient lift to hover in the Martian atmosphere. Integrated with sensors and wireless communication devices, these flyers would work in a swarm, with a mobile base serving as their recharging station and a main communication center.
Micro-air vehicle
Given the NIAC Phase I award, researchers want to determine the wing design, motion, and weight that can hover with optimal power in Mars’ atmospheric conditions and to assess the hummingbird micro-air vehicle – one of only a few robotic flappers in the world that can fly on Earth – in Mars conditions.
Should the team go on to receive a Phase II award, the goal will be to build on this research by addressing the maneuverability, wind gust rejection, takeoff/landing, power implications, remote sensing, and mission optimization of the Marsbees.
“Our long-term overarching goal is to develop swarms of Marsbees that can help with the human exploration on Mars,” Kang says in a UAH press statement.

Rocket Lab’s key goal is to achieve an unprecedented launch frequency thanks to a vertically integrated vehicle manufacturing process that enables Rocket Lab to roll an Electron vehicle off the production line every week.
Rocket Lab has rapidly scaled production of the Electron launch vehicle across its three-acre headquarters and production facility in Huntington Beach, California. The company will produce 100 3D printed Rutherford engines this year to support a monthly launch cadence by the end of 2018.
Rocket Lab has posted this video at:

“After the weekend drive, the [Curiosity] rover ended up in a spot that was a little too unstable to pass the Slip Risk Assessment Process (SRAP),” reports Ryan Anderson, a planetary geologist at the USGS in Flagstaff, Arizona.
Anderson adds that this means that there is a slight chance that the rover’s footing might shift if the robotic arm is extended, which is not ideal for the safety of Curiosity’s contact science instruments.

Making tracks
The Mars robot is now in Sol 2011 and the plan as scripted makes no use of the rover’s arm and instead focuses on remote sensing. “Take only pictures, leave only wheel tracks,” notes Anderson.
The rover is slated to start off with two Chemistry and Camera (ChemCam) Remote Micro-Imager (RMI) mosaics of the Peace Vallis alluvial fan on the crater floor.
“The air is clear right now, but is expected to get dusty later this season,” Anderson explains, “so it is important to get these very long distance images while we can.”

Drive ahead
Next, ChemCam will measure the chemistry of the targets “Morven”, “Insch”, and “Pabay.” The rover’s Mastcam then will take four mosaics: two that cover the three ChemCam targets, and two more looking for changes in the bedrock at other locations. Navcam will then finish up, watching for dust devils and clouds around midday and in the late afternoon.

“The plan is to wrap up observations at this location in the Sol 2012 plan and then drive to the southeast,” Anderson concludes.
New traverse map
Meanwhile, a new Curiosity traverse map through Sol 2009 has been issued.

The core module of China’s space station — “Tianhe-1” — was unveiled at Tianjin Aerospace Town in north China last Saturday and spotlighted on the China Global Television Network, or CGTN.
Tianhe-1 is the main control cabin of China’s space station and holds habitable living quarters and working space for a crew of three astronauts, who will manage guidance, navigation and control for the entire space station.

The module also contains a non-habitable service section and a docking hub.
In debuting the Tianhe-1 core module, also on display by engineers from China Aerospace Science and Technology Corporation (CASC) was a robotic arm. Space robotic arms, it was noted, can be of great help to astronauts when it comes to grabbing, holding and moving objects.

Station components
In early March this year, CASC said that the Tianhe-1 module would be launched on board a new-generation Long March-5 heavyweight carrier rocket in 2018. Following that launch, a series of boosts of other components of the space station are planned, including two space labs that will dock with the core module – in the next four years or so.
As reported by China Central Television (CCTV), the complete space station will consist of one core module and two experiment modules, each weighing over 20 tons, and can be joined with two manned spacecraft and one cargo spacecraft.

Post-2024, only working station
The average age of the current development team of China’s space station project is around 35, explained Zhu Guangchen, deputy chief designer of the space station.
The China News Service reported last week that the Astronaut Center of China in Beijing is moving forward on astronaut training for constructing the country’s space station, including underwater exercises and survival training in the desert,
“It is possible that China’s space station will be the only working station after 2024 when the [International Space Station] ISS is expected to retire and China will take a dominant position in conducting space experiments,” said Jiao Weixin, a space science professor at Peking University, in a story appearing in China’s Global Times on Sunday.

The Space Barons: Elon Musk, Jeff Bezos, and the Quest to Colonize the Cosmos by Christian Davenport, PublicAffairs, New York 2018; 320 pages, hardcover, $28.00.
Christian Davenport is a staff writer at the Washington Post covering the space and defense industries for the financial desk, joining the Post in 2000.
You’ll find a very enjoyable, behind-the-scenes look at the well-heeled, big-buck billionaire entrepreneurs who are reshaping the commercial space program. Space Barons, of the likes of Elon Musk of SpaceX and Amazon.com leader, Jeff Bezos, along with Richard Branson and Paul Allen-are taking innovative tactics to reshape and rekindle private space activities.
Davenport has used his sharp-eyed, journalistic talents to tell a compelling story about a “new Space Age” – one that is being propelled by the dollars of the world’s richest people to curb governmental monopoly of utilizing space. The volume also portrays the rivalry between space startups, as well as how they are upsetting the established aerospace community: old space, versus new space.
As the author notes, “Musk, the brash hare, was blazing a trail for others to follow, while Bezos, the secretive and slow tortoise, who was content to take it step by step in a race that was only just beginning.”
The book is divided into three parts, including a tell-all timeline that runs from September 2000 to September 2017 showing the growth of entrepreneurial space progress – and failure. In the book’s notes section you’ll also find useful resources for each part of the book.
This is a must-read volume that is not only well-written but offers a treasure-trove of facts that underscore the trans-formative times we live in…as private sector space reshapes low Earth orbit, a return to the Moon, planting humans on Mars and setting sail for destinations beyond.
