NASA’s Curiosity rover is now in Sol 1949, taking in views of Mt. Sharp in the neighborhood.
The recent weekend plan on Sol 1947 called for Mastcam observation of the target “Montrose”, the first of a pair of images intended to watch for any changes in the soil at this location, reports Ryan Anderson, a planetary geologist at the USGS in Flagstaff, Arizona.
After that, the rover’s Chemistry and Camera (ChemCam) was slated to do a calibration observation and two analyses of targets “Thurso” and “Loch Tay,” followed by Mastcam documentation of those targets.
In the afternoon of Sol 1947, the robot’s Mars Hand Lens Imager (MAHLI) was to take pictures of Thurso and Loch Tay. The rover’s Alpha Particle X-Ray Spectrometer (APXS) was slated to perform a short measurement of Thurso, and then an overnight measurement of Loch Tay.

On the plan for Sol 1948, ChemCam was set to do the long-distance imaging of Mt. Sharp, followed by a measurement of “Loch Scridain”.
Mastcam was tagged to document the ChemCam target, and then has several mosaics of the target “Harris Bay”. In the late afternoon on Sol 1948, ChemCam and Mastcam will do some “flat field” observations of the sky.
“Flat fields are used to check for, and potentially correct for, things like dust on the optics of a camera,” Anderson says.
Short drive
On Sol 1949, Curiosity’s Mastcam and Navcam were scheduled some atmospheric observations to measure the amount of dust in the atmosphere, and Mastcam will follow up with a second observation of “Montrose” to look for changes.
The plan then calls for Curiosity to do a short drive, and collect post-drive imaging so ground controllers and scientists can plan this week’s activities,” Anderson concludes.
The European Space Agency’s Space Debris Office in Darmstadt, Germany has updated its prediction of when China’s Tiangong-1 space lab will reenter.
The posted January 26 estimate is roughly March 18 to roughly April 12 – noting that this current estimated window “is highly variable.”
According to the ESA office, due to the orbital inclination of the Tiangong-1, approximately 42.8 degrees, and the likely uncontrolled nature of the reentry, the final impact point can be anywhere on Earth between 42.8 degrees North and 42.8 degrees South in latitude, e.g. Spain, France, Portugal, Greece, etc. Areas outside of these latitudes can be excluded, they add.
Controlled/uncontrolled?
ESA explains that in March 2016 the Tiangong-1 space station ceased functioning but maintained its structural integrity.
“In so far as can be fully confirmed,” notes the ESA office, “ground teams lost control with the craft, and it can no longer be commanded to fire its engines. It is, therefore, expected to make an ‘uncontrolled reentry.’”
Earlier this month, a Chinese space engineer indicated that the country’s Tiangong-1 space lab is not out of control.
“We have been continuously monitoring Tiangong-1 and expect to allow it to fall within the first half of this year,” explains Zhu Congpeng, an engineer at the China Aerospace Science and Technology Corporation, notifying the state-run Science and Technology Daily newspaper.
“It will burn up on entering the atmosphere,” Zhu said, “and the remaining wreckage will fall into a designated area of the sea, without endangering the surface,” he said, remarks also relayed via a January 7 story by Reuters.
Limited control
“I think the confusion comes from the fact that control is limited to the attitude of the space lab – but not to the orbit,” explains Holger Krag, Head of the Space Debris Office for ESA in Darmstadt, Germany.
Attitude control has (hardly) no impact on the orbit, Krag said, “and a deorbit impact point cannot be achieved. Orbit control requires a meaningful propulsion function, which is not available/defunct,” he told Inside Outer Space.
With its 8.5 metric tons of (initial) mass, Tiangong-1 (whose name means “Heavenly Palace” in Chinese) was rocketed into Earth orbit in late September 2011. It is the first space station built and launched by China. It was designed to be a crewed lab as well as an experiment/demonstration for the larger, multiple-module space station.

NASA’s Opportunity Mars rover has just passed 14 years of exploring the Red Planet.
The robot has been working on Mars since landing in Meridiani Planum on January 25, 2004.
Originally intended to last 90 days, the machine is still trekking and is continuing her winter exploration of “Perseverance Valley” on the west rim of Endeavour Crater from a location in the north fork of the local flow channel.
Flight software update
On Sol 4977 (Jan. 23, 2018), Opportunity received the latest version of flight software, copied over the older fallback version in preparation for a flight software update scheduled for later in the year.
On Sol 4970 (Jan. 16, 2018), Opportunity benefited from a significant dust cleaning of the solar arrays, which happens this time of year. The rover’s robotic arm, its Alpha Particle X-ray Spectrometer (APXS), and Microscopic Imager (MI) continue to be utilized.
Opportunity has moved along the north fork of the local flow channel. It spent several sols completing stereo, color panoramas, performed targeted 13-filter imaging, as well as wheeling to selected surface targets for closer investigation.
Batteries: signs of aging
Earlier in the month, ground controllers prepared and executed a test of the Zero Degree Heater (ZDH) on the rover’s batteries.
“Opportunity’s batteries have performed very well over the mission’s lifetime but are showing some signs of aging. Martian environment is quite cold and it was suspected that warming the battery during the recharge process may make the battery both more effective and degrade slower,” according to a JPL Opportunity Update.
Odometry reading
Though never used in flight, the ZDH was intended to warm the battery.
“Since it has never been turned on in flight we wanted to be very cautious before using it operationally and so a testing campaign was formulated. The first original test in this campaign was to turn it on briefly, manually (as opposed to thermostatically), and in a controlled and recoverable (in the case of a fault) setting,” the update notes. “This test was executed in the morning of Sol 4964 (Jan. 10, 2018), and appears to have been successful.”
Since touchdown on Mars, total odometry for the robot now stands at over 28 miles (45 kilometers).
There was a “secret” satellite onboard Rocket Lab’s “Still Testing” Electron launch vehicle that lifted off from New Zealand on January 21.
Now in orbit is “Humanity Star,” created by Rocket Lab founder and CEO Peter Beck.
Still Testing also orbited a Dove Pioneer Earth-imaging satellite for launch customer Planet, as well as two Lemur-2 satellites for Spire, a weather and ship tracking company.
Geodesic sphere
The Humanity Star is a geodesic sphere made from carbon fiber with 65 highly reflective panels. It spins rapidly, reflecting the sun’s rays back to Earth, creating a flashing light that can be seen against a backdrop of stars.
Orbiting the Earth every 90 minutes and visible from anywhere on the globe, the Humanity Star is designed to be a bright symbol and reminder to all on Earth about our fragile place in the universe, explains Beck.
Bright, blinking
“No matter where you are in the world, rich or in poverty, in conflict or at peace,” Beck explains, “everyone will be able to see the bright, blinking Humanity Star orbiting Earth in the night sky. My hope is that everyone looking up at the Humanity Star will look past it to the expanse of the universe, feel a connection to our place in it and think a little differently about their lives, actions and what is important.”
The Humanity Star will orbit the Earth for approximately nine months before its orbit starts to decay and it is pulled back into the Earth’s gravity.

China has successfully made its first Lunar Laser Ranging measurements, making use of the Apollo 15 Lunar Laser Ranging RetroReflector (LRRR) array – equipment deployed on the Moon in 1971.
The applied astronomy group from the Yunnan Observatories measured the distance between the Apollo 15 retro-reflector and the Yunnan Observatories ground station.
Results of Lunar Laser Ranging (LLR) measurements are valuable in the study of astro-geodynamics, Earth-moon system dynamics and lunar physics. China’s LLR program joins the United States, France and Italy in harnessing the capability.
Focus on science
Apollo 15’s Falcon lunar module was piloted by David Scott and James Irwin to a landing spot at Hadley Rille.
Apollo 15 was the ninth piloted mission in the United States’ Apollo program, the fourth to land on the Moon. It was the first of what were termed “J missions” – long stays on the Moon, with a greater focus on science than had been possible on previous missions. That Apollo mission was first to utilize a lunar rover for increased mobility of moonwalkers on the surface.

Far side lander
The LLR was conducted in the context of China preparing to launch the Chang’e-4 lunar probe this year that will attempt the first soft landing on the far side of the Moon.
“In the near future, China will plant its own retro-reflector on the Moon, which will further boost the development of LLR in China,” said Li Yuqiang, an associate researcher with Yunnan Observatories, as reported by the Xinhua news agency.

Scott Guzewich, an atmospheric scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, reports that a recent drive of the Curiosity Mars rover has put the robot near the edge of the Vera Rubin Ridge.
“Curiosity diverted from our primary ‘Mount Sharp Ascent Route’ a couple weeks ago as we continued to investigate the outcrops of bluish-toned rock that are scattered around this region of the Vera Rubin Ridge,” Guzewich notes.
The rover is now in Sol 1945 overlooking the “clay unit” that it will eventually reach.
Work to do
“We still have work to do in the hematite-rich Vera Rubin Ridge and so we must return to our original path eastward along the ridge and will begin that with a drive on the second sol of today’s plan,” Guzewich adds.
But before the rover departs, Curiosity will finish investigating the science goal of this location: studying a transition in rock tones between more gray-blue tones and those familiar martian orange-reds.
Contact science
Contact science is slated on one of the redder-toned rocks, “Loch Gairloch”, with Alpha Particle X-Ray Spectrometer (APXS) and Mars Hand Lens Imager (MAHLI), Guzewich explains.
That will be followed by a series of Chemistry & Camera (ChemCam) Laser-Induced Breakdown Spectrometer (LIBS) rasters on a suite of both bluish and reddish rocks in the rover’s workspace: “Callander,” “Moidart,” and “Kirkcolm.”
In addition, Mastcam images will be taken of those nearby targets as well as some more distant features, “Eriskay,” “Glen Tilt,” and “Broadford” along the rover’s future drive path, Guzewich concludes.
New traverse map
Meanwhile, a new Curiosity traverse map through Sol 1944 has been issued.
The map shows the route driven by the robot through the 1944 Martian day, or sol, of the rover’s mission on Mars (January 24, 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 1942 to Sol 1944, Curiosity had driven a straight line distance of about 47.88 feet (14.60 meters), bringing the rover’s total odometry for the mission to 11.21 miles (18.05 kilometers).
The base image from the map is from the High Resolution Imaging Science Experiment Camera (HiRISE) in NASA’s Mars Reconnaissance Orbiter.
Littleton, Colorado – NASA’s next Mars mission is reaching “ship and shoot” status, a lander geared this year to start probing the Red Planet’s deep interior and even eavesdrop on rumbling Marsquakes.
As spacecraft names go, it’s a mouthful: Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. That has been mercifully shortened to InSight.
A wonderful moment early this morning for Barbara and myself at Lockheed Martin Space Systems – the unfurling of the solar arrays on the InSight Mars spacecraft.
Technicians took great care in monitoring the deployment of the solar panels, a final test before being reeled back in on the Mars-bound craft.
The InSight Mars lander is nearing its Colorado departure to Vandenberg Air Force Base in California.
Liftoff of the spacecraft is targeted for May 5th!

Over the weekend Curiosity completed a drive that took the robot to the very southern edge of Vera Rubin Ridge (VRR), reports Roger Wiens, a geochemist at the Los Alamos National Laboratory in New Mexico. “So we have downhill slopes directly in front of and around the side of the rover, though we plan to continue exploring the ridge for a while,” he adds.

The rover team is using the images gleaned over the weekend to look for potential geological relationships between VRR and the clay unit that lies south of it, explains Wiens.
New selfie coming!
A newly written plan calls for the rover to take its first selfie since Sol 1466 (at the Quela drill site) back in September, 2016, and with the Murray Buttes in the scene.
Curiosity’s to-do list also includes taking a close-up of the Remote Warm Electronics Box (RWEB) window that ChemCam looks out of – a check for dust. “So far the window has been very clean throughout the mission; this is just another routine check,” Wiens notes.
The robot’s Chemistry and Camera (ChemCam) is slated to do a 5×1 raster on “Foyers” and a 10×1 raster on “Eaval,” and Mastcam will image these targets too.
Also, the Alpha Particle X-Ray Spectrometer (APXS) will take advantage of the dust removed from “Eaval” by ChemCam’s laser, and will do an overnight observation on that target, which will also be imaged by the rover’s Mars Hand Lens Imager (MAHLI).

In addition, the robot will take Dynamic Albedo of Neutrons (DAN) passive data and also Radiation Assessment Detector (RAD) and Rover Environmental Monitoring Station (REMS) data.
Straight south
On the next sol, Curiosity’s Mastcam will take a 12×2 mosaic of “Glen Tilt.” ChemCam will take passive spectra of several calibration targets on the rover, Wiens points out.
After that, the rover will spend 13 minutes driving about 82 feet (25 meters) nearly straight south, Wiens concludes, taking a short dip off the ridge. The rover will finish by taking images from its new position and sending the data home.
6th Earth year on Mars
“Having spent 1943 sols on the surface of Mars, Curiosity is in its 6th Earth year on Mars, but it is in its 3rd Mars year of exploration,” Wiens explains. “That means Curiosity has encountered this season of the year twice before.”
The Mars machinery is just a little past the deepest part of winter in the southern hemisphere, where Curiosity roams.
Day in history
“On this day in history in Mars year 32 (which happened to be 19-April-2014 on Earth), Curiosity was just arriving at the Kimberley site, where she found manganese-oxide fracture fills and sanidine-rich sediments,” Wiens continues.
“And on this day one Mars year ago (March 6, 2016), Curiosity was climbing onto the Naukluft Plateau, starting to round the corner after its first encounter with the Bagnold Dunes, and prior to encountering the Murray Buttes,” Wiens says. “What a journey it has been for this intrepid rover!”
A new space tourism market report is forecasting growth at the Compound Annual Growth Rate (CAGR) of 14.34 percent from 2017-2021.
For years, space tourism was an option only for the richest of the population ever since Dennis Tito went on a commercial orbital space tour in 2001.
Since that time, nine more people have taken up 10 such tours, spending a minimum of $20 million on each trip. These people have been categorized under the first generation of space tourists.
Growth prospects
The new report covers the present scenario and the growth prospects of the global space tourism market for 2017-2021. To calculate the market size, the report considers the investment made in commercial space tourism services.
Technavio’s analysts forecast the global space tourism market to grow at a CAGR of 14.34% during the period 2017-2021. The report covers the market landscape and its growth prospects over the coming years. The report also includes a discussion of the key vendors operating in this market.
Technavio is a market research company with global coverage.
Latest trend
One of the latest trends that will gain traction in the space tourism market in the coming years, the study group has noted, is the decrease in the cost of space tourism.
“The cost of getting into space will decline rapidly if the next generation of space planes can reach the orbit. This will considerably reduce the cost of launching satellites or space exploration missions, making it an economically feasible option for a larger customer segment.”
