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 1800 to Sol 1802, Curiosity has driven a straight line distance of about 47.03 feet (14.34 meters).
That movement has brought the rover’s total odometry for the mission to 10.76 miles (17.32 kilometers).

A heist story set on the Moon – early PR for Andy Weir’s new novel: Artemis.
The bestselling author of The Martian returns with a new near-future thriller.
According to Penguin Random House:
“Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you’re not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you’ve got debts to pay and your job as a porter barely covers the rent.”
Everything changes when Jazz sees the chance to commit the perfect crime, with a reward too lucrative to turn down, explains the PR blurb. “But pulling off the impossible is just the start of her problems, as she learns that she’s stepped square into a conspiracy for control of Artemis itself—and that now, her only chance at survival lies in a gambit even riskier than the first.”

NASA’s next Mars rover is being readied for the Red Planet. To be launched in July/August 2020 and slated for arrival in February 2021, it is the most complex piece of machinery ever plopped down on that distant world.
Once on the planet, the nuclear-powered Mars 2020 rover has unusual duties compared to predecessor robots. To achieve a checklist of jobs it is imbued with far more software smarts to land upon and traverse across Mars while rapidly carrying out an agenda of scientific tasks.

The soon-to-launch SpaceX Falcon Heavy is billed by the company as the world’s most powerful operational rocket. Its maiden flight is slated for November, rocketing off pad 39A at the Kennedy Space Center in Florida.
No matter how you look at it – Falcon Heavy is a big deal.
Its first stage is composed of three Falcon 9 nine-engine cores adding up to 27 Merlin engines.
The twenty-seven Merlin engines that power Falcon Heavy’s three cores are arranged in an “Octaweb” structure.

Excitement guaranteed
“There’s a lot that could go wrong there. I encourage people to come down to the Cape to see the first Falcon Heavy mission. It’s guaranteed to be exciting,” said Elon Musk founder, CEO and lead designer at SpaceX.
“I hope it makes it far enough away from the pad that it doesn’t cause pad damage,” Musk said. “I would consider even that a win to be honest. Yeah…a major pucker factor really is the only way to describe it.”

Now performing Sol 1802 duties, NASA’s Curiosity’s Mars rover drove on Sol 1801 bringing it to an excellent location for contact and remote science as part of a 3-sol plan that sets up the robot for a long Labor Day weekend.
That’s the report from Rachel Kronyak, a planetary geologist from the University of Tennessee in Knoxville.
Murray bedrock
The plan called for kicking off Sol 1802 with contact science, using Curiosity’s Mars Hand Lens Imager (MAHLI) plus the Alpha Particle X-Ray Spectrometer (APXS). The target is called “Tyler” – a region of Murray bedrock just in front of the rover.

“We’ll then enter into a very full, science-packed remote science block,” Kronyak notes, during which the rover will make Chemistry and Camera laser-induced breakdown spectroscopy (ChemCam LIBS) observation on Tyler and take a number of Mastcam mosaics.
“These mosaics will look at sedimentary structures and layering within the beautifully exposed rocks of the Vera Rubin Ridge in front of us,” Kronyak adds. The mosaics are fairly extensive and will document the targets named “Pettegrove Point,” “Rumills Hub,” “Mink Rocks,” “The Downfall,” and “Popplestone Ledge.”
Stereo mosaics
“Most of the Mastcam observations in the plan are actually stereo mosaics, which means we take each image with both the left and right eyes of Mastcam,” Kronyak explains. “Stereo mosaics are pretty resource intensive, but they provide us with three-dimensional depth information, which is especially useful for making geologic interpretations.”

Following Curiosity’s heavy science block, the robot will drive and collect standard post-drive images to set up for contact and remote science over the weekend. Also on tap is a post-drive Dynamic Albedo of Neutrons (DAN) and Rover Environmental Monitoring Station (REMS) observations, Kronyak concludes.

We’ll also do a post-drive DAN active along with our standard DAN passive and REMS observations.
It’s a big Universe – anybody out there?

The “Breakthrough Listen” campaign, a project to find signs of intelligent life in the universe, has detected 15 fast radio bursts (FRBs) emanating from the mysterious “repeater” FRB 121102.
Could these brief, bright pulses of radio emission from distant galaxies be signatures of extraterrestrial technology?
Breakthrough Listen is a global astronomical initiative launched in 2015 by Internet investor and philanthropist Yuri Milner and cosmologist Stephen Hawking.

Telescope observations
Breakthrough Listen announced today that West Virginia-based Green Bank Telescope observations of a dwarf galaxy three billion light years away reveal 15 bursts of radio emission. This is the first time bursts from this source have been seen at these frequencies.
The Listen science team at UC Berkeley added FRB 121102 to their list of targets. In the early hours of Saturday, August 26, UC Berkeley Postdoctoral Researcher Vishal Gajjar observed the location of FRB 121102 using the Breakthrough Listen digital backend instrument at the Green Bank facility.
New pulses
Analysis by Gajjar and the Listen team revealed 15 new pulses from FRB 121102. As well as confirming that the source is in a newly active state, the high resolution of the data obtained by the Listen instrument will allow measurement of the properties of these mysterious bursts at a higher precision than ever possible before.

The Listen backend, which is able to record several gigahertz of bandwidth at a time, split into billions of individual channels, enable a new view of the frequency spectrum of FRBs, and should shed additional light on the processes giving rise to FRB emission.
Possible explanations
Whether or not FRBs are indeed signatures of extraterrestrial technology remains a TBD, according to Breakthrough Listen.

According to a press statement released today: “Possible explanations for FRBs range from outbursts from rotating neutron stars with extremely strong magnetic fields, to more speculative ideas that they are directed energy sources used by extraterrestrial civilizations to power spacecraft.”
Observations may indicate FRB 121102 is currently in a heightened activity state, notes Gajjar “and follow-on observations are encouraged, particularly at higher radio frequencies.”

Projection of things to come. BTW: notice the SpaceX disappearing act from previous NASA charts and the addition of China for a return sample mission. Credit: NASA
NASA is blueprinting its beyond Mars 2020 rover plans, focusing on returning samples from the Red Planet.
In a “Review of Progress Toward Implementing the Decadal Survey Vision and Voyages for Planetary Sciences” briefing yesterday at the J. Erik Jonsson Woods Hole Center in Woods Hole, Massachusetts, Thomas Zurbuchen, NASA’s Science Mission Directorate Associate Administrator detailed some Mars sample return thinking.

NASA’s Lunar Reconnaissance Orbiter (LRO) used its LROC imaging system to look back at Earth and snag imagery during the Great American Solar Eclipse on August 21.
As LRO crossed the lunar south pole heading north at 3,579 miles per hour (1600 meters per second, the shadow of the Moon was racing across the United States at 1,500 miles per hour (670 meters per second).
A few minutes later, LRO began a slow 180° turn to look back at the Earth and capture an image of the eclipse very near the spot of maximum length of totality.

The Lunar Reconnaissance Orbiter Camera’s (LROC) Narrow Angle Camera began scanning the Earth at 18:25:30 UTC and completed the image 18 seconds later (UTC is 4 hours ahead of Eastern Daylight Time, or 7 hours ahead of Pacific Daylight Time).
Typical day on Moon
“While all of Monday’s thrill was in experiencing the shadow of the Moon sweep across us on Earth, on the Moon this was just another typical day,” said Mark Robinson of Arizona State University, and principal investigator of the Lunar Reconnaissance Orbiter Camera.
“The lunar nearside was one week into its two-week night, while the Sun shone on the farside in the middle of its two-week day. For the Moon, and the LRO spacecraft observing the Moon, the real excitement is during a lunar eclipse when the shadow of the Earth sweeps across the Moon.”

Temperature drop
Robinson added that during the eclipse, the lunar surface temperatures drop rapidly and LRO’s thermal imager, the Diviner Lunar Radiometer, can learn about the material properties of the lunar rocks and soils by studying their temperature just after the lights abruptly go out.
“Though for the LRO spacecraft itself, the Earth’s shadow means that most of the other instruments must be powered down because of the lack of power coming from the solar panels,” Robinson pointed out.
Launched on June 18, 2009, LRO has collected a treasure trove of data about the Moon with its seven powerful instruments. LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington, D.C.

NASA’s Curiosity Mars rover is now closing out Sol 1799 duties.
The robot drove some 76 feet (23.3 meters) over the weekend bringing the robot even closer to the area it will ascend Vera Rubin Ridge.
“We have reached the point in the traverse where we are no longer headed east along the ridge, but instead are turning to the south where orbital data show the ridge has slopes shallow enough for Curiosity to climb,” reports Abigail Fraeman, a planetary geologist at NASA/Jet Propulsion Laboratory in Pasadena, California.

Charge of the batteries
Curiosity acquired Mastcam and ChemCam Remote Micro-Imager (RMI) images of the ridge in the weekend plan, including a last “official” approach imaging mosaic.
“These images continue to show very interesting, fine scale sedimentary structures that hold the secrets of how the lower ridge layers were deposited,” Fraeman notes.
One of the big challenges putting a new plan together was making sure the observations researchers wanted didn’t leave the rover’s batteries too drained at the end of the plan.

“We keep careful track of the expected state of charge of the batteries because we want to make sure they will last a long time, and because we want to have enough power available going into the next sol’s plan,” Fraeman points out. “Getting everything to fit inside power guidelines was challenging today in part because late autumn has come to Gale Crater. Colder temperatures mean we have to run heaters for longer, which takes more energy.”
Two sol script
A two sol plan has been scripted, starting off on Sol 1800 with contact science, including Mars Hand Lens Imager (MAHLI) and Alpha Particle X-Ray Spectrometer (APXS) observations of an interesting eroded Murray formation rock target named “Bauneg Beg.”
Following the contact science, Curiosity is to make ChemCam LIBS [laser-induced breakdown spectroscopy] observations of targets “Bucklin Rock” and “Gilkey Harbor,” and then take a 12×1 Mastcam right eye mosaic that will cover the area directly in front of the rover. Bucklin Rock looks similar to Bauneg Bag, and Gilkey Harbor is a dark, smooth rock.

Southward ho
“After our morning science, Curiosity will drive south towards Vera Rubin Ridge,” Fraeman adds.
“After the drive on sol 1801, Curiosity will do some untargeted remote sensing, including collecting some data from the ChemCam calibration targets, and taking a Navcam suprahorizon movie, performing a dust devil search, and looking at the Sun to assess the amount of dust in the atmosphere (a tau measurement),” Fraeman concludes.
