Latest on the Mars rovers + Curiosity finds signs of a warm & wet Red Planet long ago

Bob Zimmerman has posted one of his periodic updates on the explorations of the Curiosity and Opportunity rovers on Mars:  Mars rover update: July 12, 2017 | Behind The Black.

In the five years since Curiosity landed in Gale Crater, it has moved only about 17 km but has done a lot of science along the way: Mid-2017 Map of NASA’s Curiosity Mars Rover Mission | NASA JPL.

This map shows the route driven by NASA’s Curiosity Mars rover, from the location where it landed in August 2012 to its location in July 2017, and its planned path to additional geological layers of lower Mount Sharp.

NASA JPL recently held a public seminar to celebrate Five Years of Curiosity on Mars and to report on what has been learned so far, especially regarding the conditions of the young Red Planet when it appears to have had an atmosphere and large bodies of water on the surface.

Nearly five years after its celebrated arrival at Mars, the Curiosity rover continues to reveal Mars as a once-habitable planet. Early in the planet’s history, generations of streams and lakes created the landforms that Curiosity explores today. The rover currently is climbing through the foothills of Mount Sharp, a 3-mile-high mountain formed from sediment brought in by water and wind. This talk will cover the latest findings from the mission, the challenges of exploration with an aging robot, and what lies ahead.

Speakers:
James K. Erickson, Mars Science Laboratory Project Manager, JPL
Ashwin R. Vasavada, Mars Science Laboratory Project Scientist, JPL

Video: Fly over Pluto and its largest moon Charon

Created from imagery and elevation data from the New Horizon probe‘s fly-by of the Pluto system in July of 2015, the videos below show what it would look like to fly low over Pluto and  its biggest moon Charon:

NASA Video Soars over Pluto’s Majestic Mountains and Icy Plains

In July 2015, NASA’s New Horizons spacecraft sent home the first close-up pictures of Pluto and its moons – amazing imagery that inspired many to wonder what a flight over the distant worlds’ icy terrain might be like.

Wonder no more. Using actual New Horizons data and digital elevation models of Pluto and its largest moon Charon, mission scientists have created flyover movies that offer spectacular new perspectives of the many unusual features that were discovered and which have reshaped our views of the Pluto system – from a vantage point even closer than the spacecraft itself.

This dramatic Pluto flyover begins over the highlands to the southwest of the great expanse of nitrogen ice plain informally named Sputnik Planitia. The viewer first passes over the western margin of Sputnik, where it borders the dark, cratered terrain of Cthulhu Macula, with the blocky mountain ranges located within the plains seen on the right. The tour moves north past the rugged and fractured highlands of Voyager Terra and then turns southward over Pioneer Terra — which exhibits deep and wide pits — before concluding over the bladed terrain of Tartarus Dorsa in the far east of the encounter hemisphere.

The equally exciting flight over Charon begins high over the hemisphere New Horizons saw on its closest approach, then descends over the deep, wide canyon of Serenity Chasma. The view moves north, passing over Dorothy Gale crater and the dark polar hood of Mordor Macula. The flight then turns south, covering the northern terrain of Oz Terra before ending over the relatively flat equatorial plains of Vulcan Planum and the “moated mountains” of Clarke Montes.

The topographic relief is exaggerated by a factor of two to three times in these movies to emphasize topography; the surface colors of Pluto and Charon also have been enhanced to bring out detail.

Digital mapping and rendering were performed by Paul Schenk and John Blackwell of the Lunar and Planetary Institute in Houston. All feature names in the Pluto system are informal.

Large sunspot erupts in a big flare and coronal mass ejection

Spaceweather.com reports on a big solar flare today:

After days of suspenseful quiet, huge sunspot AR2665 finally erupted on July 14th (0209 UT), producing a powerful and long-lasting M2-class solar flare. Extreme ultraviolet telescopes onboard NASA’s Solar Dynamics Observatory recorded the blast:

This image combines three images with different temperatures. Each image is assigned a color, and they are not the same used in the single images. Here AIA 094 is red, AIA 335 is green, and AIA 193 is blue. Each highlights a different part of the corona.

The two hour long outburst of X-rays and high energy particles led to lots of ionization in earth’s upper atmosphere:

Shortwave radio blackouts were subsequently observed over the Pacific Ocean and especially around the Arctic Circle.   This map from NOAA shows the affected geographic regions.

See these space weather reports from NOAA for more about the effects of the solar flare on earth:

The GIF below of images from the Solar Dynamics Observatory satellite shows a subsequent coronal mass ejection (CME). The plasma of ionized protons and electrons will reach earth by July 16 and should generate some vivid auroras: G2 (Moderate) Geomagnetic Storm Watch Issued – Valid for 16-17 Jul 2017 | NOAA / NWS Space Weather Prediction Center –

Video: “Space to Ground” report on the ISS – July.14.2017

Here is this week’s Space to Ground report from NASA on activities related to the International Space Station:

And here is the first in what looks to be a fun series of brief videos from ISS crew member Jack Fischer describing some aspect of the huge station:

No one knows the International Space Station better than the people who live and work there—and now they’re sharing that knowledge in bite-sized chunks. In the first of a series of short videos called “SpeedyTime,” Expedition 52 flight engineer Jack Fischer gives us a quick-but-thorough tour of payload activities inside and outside the airlock in the station’s Japanese laboratory module, Kibo.
