Volcanic activity on Io was discovered by Voyager 1 imaging scientist Linda Morabito. She spotted a little bump on Io’s limb while analyzing a Voyager image and thought at first it was an undiscovered moon. Moments later she realized that wasn’t possible — it would have been seen by earthbound telescopes long ago. Morabito and the Voyager team soon came to realize they were seeing a volcanic plume rising 190 miles (300 km) off the surface of Io. It was the first time in history that an active volcano had been detected beyond the Earth. For a wonderful account of the discovery, click here.
Linda Morabito spotted the puzzling plume off Io’s limb in this photo, taken on March 8, 1979, three days after Voyager 1’s encounter with Jupiter. It really does look like another moon poking out from behind Io. A second plume over the terminator (border between day and night) catches the rays of the rising Sun. Credit: NASA / JPL
Today, we know that Io boasts more than 130 active volcanoes with an estimated 400 total, making it the most volcanically active place in the Solar System. Juno used its Jovian Infrared Aurora Mapper (JIRAM) to take spectacular photographs of Io during Perijove 7 last July, when we were all totally absorbed by close up images of Jupiter’s Great Red Spot.
Io is captured here by NASA’s Galileo spacecraft. Deposits of sulfur dioxide frost appear in white and grey hues while yellowish and brownish hues are probably due to other sulfurous materials.

Juno’s Io looks like it’s on fire. Because JIRAM sees in infrared, a form of light we sense as heat, it picked up the signatures of at least 60 hot spots on the little moon on both the sunlight side (right) and the shadowed half. Like all missions to the planets, Juno’s cameras take pictures in black and white through a variety of color filters. The filtered views are later combined later by computers on the ground to create color pictures. Our featured image of Io was created by amateur astronomer and image processor Roman Tkachenko, who stacked raw images from this data set to create the vibrant view.

Io’s hotter than heck with erupting volcano temperatures as high as 2,400° F (1,300° C). Most of its lavas are made of basalt, a common type of volcanic rock found on Earth, but some flows consist of sulfur and sulfur dioxide, which paints the scabby landscape in unique colors.
This five-frame sequence taken by NASA’s New Horizons spacecraft on March 1, 2007 captures the giant plume from Io’s Tvashtar volcano.
Located more than 400 million miles from the Sun, how does a little orb only a hundred miles larger than our Moon get so hot? Europa and Ganymede are partly to blame. They tug on Io, causing it to revolve around Jupiter in an eccentric orbit that alternates between close and far. Jupiter’s powerful gravity tugs harder on the moon when its closest and less so when it’s farther away. The “tug and release”creates friction inside the satellite, heating and melting its interior. Io releases the pent up heat in the form of volcanoes, hot spots and massive lava flows.

The Parker Solar Probe is the size of a small car and named for Prof. Eugene Parker, a 90-year-old American astrophysicist who in 1958 discovered the solar wind. It’s the first time that NASA has named a spacecraft after a living person. The Parker probe will launch between July 31 and August 19 but not immediately head for the Sun. Instead it will make a beeline for Venus for the first of seven flybys. Each gravity assist will slow the craft down and reshape its orbit (see below), so it later can pass extremely close to the Sun. The first flyby is slated for late September.
When heading to faraway places, NASA typically will fly by a planet to increase the spacecraft’s speed by robbing energy from its orbital motion. But a probe can also approach a planet on a different trajectory to slow itself down or reconfigure its orbit.
The spacecraft will swing well within the orbit of Mercury and more than seven times closer than any spacecraft has come to the Sun before. When closest at just 3.9 million miles (6.3 million km), it will pass through the Sun’s outer atmosphere called the corona and be subjected to temperatures around 2,500°F (1,377°C). The primary science goals for the mission are to trace how energy and heat move through the solar corona and to explore what accelerates the solar wind as well as solar energetic particles.
The Parker Solar Probe will use seven Venus flybys over nearly seven years to gradually shrink its orbit around the Sun, coming as close as 3.7 million miles (5.9 million km), well within the orbit of Mercury. Closest approaches (called perihelia) will happen in late December 2024 and the first half of 2025 before the mission ends. Credit: NASA
The vagaries of the solar wind, a steady flow of particles that “blows” from the Sun’s corona at more than million miles an hour, can touch Earth in beautiful ways as when it energizes the aurora borealis. But it can also damage spacecraft electronics and poorly protected power grids on the ground. That’s why scientists want to know more about how the corona works, in particular why it’s so much hotter than the surface of the Sun — temperatures there are several million degrees.
During the probe’s closest approach, the Sun’s apparent diameter will span 14° of sky. Compare that to the ½° Sun we see from Earth. Can you imagine how hot the Sun’s rays would be if it were this large from Earth? Life as we know it would be over. Wikipedia / CC BY-SA 3.0
As you can imagine, it gets really, really hot near the Sun, so you’ve got to take special precautions. To perform its mission, the spacecraft and instruments will be protected from the Sun’s heat by a 4.5-inch-thick carbon-composite shield, which will keep the four instrument suites designed to study magnetic fields, plasma and energetic particles, and take pictures of the solar wind, all at room temperature.
Similar to how the Juno probe makes close passes over Jupiter’s radiation-fraught polar regions and then loops back out to safer ground, the Parker probe will make 24 orbits around the Sun, spending a relatively short amount of face to face time with our star. At closest approach, the spacecraft will be tearing along at about 430,000 mph, fast enough to get from Washington, D.C., to Tokyo in under a minute, and will temporarily become the fastest manmade object. The current speed record is held by Helios-B when it swung around the Sun at 156,600 mph (70 km/sec) on April 17, 1976.

Many of you saw last August’s total solar eclipse and marveled at the beauty of the corona, that luminous spider web of light around Moon’s blackened disk. When closest to the Sun at perihelion the Parker probe will fly to within 9 solar radii (4.5 solar diameters) of its surface. That’s just about where the edge of the furthest visual extent of the corona merged with the blue sky that fine day, and that’s where Parker will be!

On September 8th. 2016, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) launched from Earth to rendezvous with the asteroid 101955 Bennu. This mission will be the first American robotic spacecraft to rendezvous with an asteroid, which it will reach by December of 2018, and return samples to Earth for analysis (by September 24th, 2023).
Since that time, NASA has been keeping the public apprised of the mission’s progress, mainly by sending back images taken by the spacecraft. The latest image was one of the Earth and Moon, which the spacecraft took using its NavCam 1 imager on January 17th, 2018. As part of an engineering test, this image shows just how far the probe has ventured from Earth.

The image was taken when the spacecraft was at a distance of 63.6 million km (39.5 million mi) from the Earth and Moon. When the camera acquired the image, the spacecraft was moving at a speed of 8.5 km per second (19,000 mph) away from Earth. Earth can be seen in the center of the image as the brightest of the two spots while the smaller, dimmer Moon appears to the right.
Several constellations are also visible in the surrounding space, including the Pleiades cluster in the upper left corner. Hamal, the brightest star in Aries, is also visible in the upper right corner of the image. Meanwhile, the Earth-Moon system is nestled between the five stars that make up the head of Cetus the Whale.
This is merely the latest in a string of photographs that show how far OSIRIS-REx has ventured from Earth. On October 2nd, 2017, the probe’s MapCam instrument took a series of images of the Earth and Moon while the probe was at a distance of 5 million km (3 million mi) – about 13 times the distance between the Earth and the Moon. NASA then created a composite image to create a lovely view of the Earth-Moon system (see below).

On September 22nd, 2017, the probe also snapped a “Blue Marble” image of Earth (seen below) while it was at a distance of just 170,000 km (106,000 mi). The image was captured just a few hours after OSIRIS-REx had completed its critical Earth Gravity Assist (EGA) maneuver, which slung it around the Earth and on its way towards the asteroid Bennu for its scheduled rendezvous in December of 2018.
On both of these occasions, the images were taken by the probe’s MapCam instrument, a medium-range camera designed to capture images of outgassing around Bennu and help map its surface in color. The NavCam 1 instrument, by contrast, is a grayscale imager that is part of Touch-And-Go Camera System (TAGCAMS) navigation camera suite.

The design, construction and testing of this instrument was carried out by Malin Space Science Systems, and Lockheed Martin is responsible for its operation. By the time OSIRIS-REx begins to approach asteroid Bennu in December of 2018, we can expect that the probes cameras will once again be busy.
However, by this time, they will be turned towards its destination. As it nears Bennu, its cameras will need to be calibrated yet again by snapping images of the asteroid on approach. And we, the public, can expect that more beautiful composite images will be shared as a result.

Some truly interesting and ambitious missions have been proposed by NASA and other space agencies for the coming decades. Of these, perhaps the most ambitious include missions to explore the “Ocean Worlds” of the Solar System. Within these bodies, which include Jupiter’s moon Europa and Saturn’s moon Enceladus, scientists have theorized that life could exist in warm-water interior oceans.
By the 2020s and 2030s, robotic missions are expected to reach these worlds and set down on them, sampling ice and exploring their plumes for signs of biomarkers. But according to a new study by an international team of scientists, the surfaces of these moons may have extremely low-density surfaces. In other words, the surface ice of Europa and Enceladus could be too soft to land on.

For the sake of their study, the team sought to explain the unusual negative polarization behavior at low phase angles that has been observed for decades when studying atmosphereless bodies. This polarization behavior is thought to be the result of extremely fine-grained bright particles. To simulate these surfaces, the team used thirteen samples of aluminum oxide powder (Al²O³).
Aluminum oxide is considered to be an excellent analog for regolith found on high aldebo Airless Solar System Bodies (ASSB), which include Europa and Encedalus as well as eucritic asteroids like 44 Nysa and 64 Angelina. The team then subjected these samples to photopolarimetric examinations using the goniometric photopolarimeter at Mt. San Antonio College.
What they found was that the bright grains that make up the surfaces of Europa and Enceladus would measure about a fraction of a micron and have a void space of about 95%. This corresponds to material that is less dense than freshly-fallen snow, which would seem to indicate that these moon’s have very soft surfaces. Naturally, this does not bode well for any missions that would attempt to set down on Europa or Enceladus’ surface.
But as Nelson explained in PSI press release, this is not necessarily bad news, and such fears have been raised before:
“Of course, before the landing of the Luna 2 robotic spacecraft in 1959, there was concern that the Moon might be covered in low density dust into which any future astronauts might sink. However, we must keep in mind that remote visible-wavelength observations of objects like Europa are only probing the outermost microns of the surface.”

So while Europa and Enceladus may have surfaces with a layer of low-density ice particles, it does not rule out that their outer shells are solid. In the end, landers may be forced to contend with nothing more than a thin sheet of snow when setting down on these worlds. What’s more, if these particles are the result of plume activity or action between the interior and the surface, they could hold the very biomarkers the probes are looking for.
Of course, further studies are needed before any robotic landers are sent to bodies like Europa and Enceladus. In the coming years, the James Webb Space Telescope will be conducting studies of these and other moons during its first five months in service. This will include producing maps of the Galilean Moons, revealing things about their thermal and atmospheric structure, and searching their surfaces for signs of plumes.
The data the JWST obtains with its advanced suite of spectroscopic and near-infrared instruments will also provide additional constraints on their surface conditions. And with other missions like the ESA’s proposed Europa Clipper conducting flybys of these moons, there’s no shortage to what we can learn from them.
Beyond being significant to any future missions to ASSBs, the results of this study are also likely to be of value when it comes to the field of terrestrial geo-engineering. Essentially, scientists have suggested that anthropogenic climate change could be mitigated by introducing aluminum oxide into the atmosphere, thus offsetting the radiation absorbed by greenhouse gas emissions in the upper atmosphere. By examining the properties of these grains, this study could help inform future attempts to mitigate climate change.
This study was made possible thanks in part to a contract provided by NASA’s Jet Propulsion Laboratory to the PSI. This contract was issued in support of the NASA Cassini Saturn Orbiter Visual and Infrared Mapping Spectrometer instrument team.

It’s no secret that China’s growth in the past few decades has been reflected in space. In addition to the country’s growing economic power and international influence, it has also made some very impressive strides in terms of its space program. This includes the development of the Long March rocket family, the deployment of their first space station, and the Chinese Lunar Exploration Program (CLEP) – aka. the Chang’e program.
Given all that, one would not be surprised to learn that China has some big plans for 2018. But as the China Aerospace Science and Technology Corporation (CASC) announced last Tuesday (on January 2nd, 2018), they intend to double the number of launches they conducted in 2017. In total, the CASC plans to mount over 40 launches, which will include the Long March 5 returning to flight, the Chang’e 4 mission, and the deployment of multiple satellites.
In 2017, China hoped to conduct around 30 launches, which would consist of the launch of a new Tianzhoui-1 cargo craft to the Tiangong-2 space lab and the deployment of the Chang’e 5 lunar sample return mission. However, the latter mission was postponed after the Long March 5 rocket that would have carried it to space failed during launch. As such, the Chang’e 5 mission is now expected to launch next year.

That failed launch also pushed back the next flight of Long March 5, which had conducted its maiden flight in November of 2016. In the end, China closed the year with 18 launches, which was four less than the national record it set in 2016 – 22 launches. It also came in third behind the United States with 29 launches (all of which were successful) and Russia’s 20 launches (19 of which were successful).
Looking to not be left behind again, the CASC hopes to mount 35 launches in 2018. Meanwhile, the China Aerospace Science Industry Corporation (CASIC) – a defense contractor, missile maker and sister company of CASC – will carry out a number of missions through its subsidiary, ExPace. These will include four Kuaizhou-1A rocket launches in one week and the maiden flight of the larger Kuaizhou-11 rocket.
In addition, Landspace Technology – a Beijing-based private aerospace company – is also expected to debut its LandSpace-1 rocket this year. In January of 2017, Landspace signed a contract with Denmark-based satellite manufacturer GOMspace to become the first Chinese company to develop its own commercial rockets that would provide services to the international marketplace.
But of course, the highlights of this year’s launches will be the Long March 5’s return to service, and the launch of the Chang’e 4 mission. Unlike the previous Chang’e missions, Chang’e 4 will be China’s first attempt to mount a lunar mission that involves a soft landing. The mission will consist of a relay orbiter, a lander and a rover, the primary purpose of which will be to explore the geology of the South Pole-Aitken Basin.

For decades, this basin has been a source of fascination for scientists; and in recent years, multiple missions have confirmed the existence of water ice in the region. Determining the extent of the water ice is one of the main focuses of the rover mission component. However, the lander will also to be equipped with an aluminum case filled with insects and plants that will test the effects of lunar gravity on terrestrial organisms.
These studies will play a key role in China’s long-term plans to mount crewed missions to the Moon, and the possible construction of a lunar outpost. In recent years, China has indicated that it may be working with the European Space Agency to create this outpost, which the ESA has described as an “international Moon village” that will be the spiritual successor to the ISS.
The proposed launch of the Long March 5 is also expected to be a major event. As China’s largest and most powerful launch vehicle, this rocket will be responsible for launching heavy satellites, modules of the future Chinese space station, and eventual interplanetary missions. These include crewed missions to Mars, which China hopes to mount between the 2040s and 2060s.
According to the GB times, no details about the Long March 5’s return to flight mission were revealed, but there have apparently been indications that it will involve the large Dongfanghong-5 (DFH-5) satellite bus. In addition, no mentions have been made of when the Long March 5B will begin conducting missions to Low Earth Orbit (LEO), though this remains a possibility for either 2018 or 2019.

Other expected missions of note include the deployment of more than 10 Beidou GNSS satellites – which are basically the Chinese version of GPS satellites – to Medium Earth Orbits (MEOs). A number of other satellites will be sent into orbit, ranging from Earth and ocean observation to weather and telecommunications satellites. All in all, 2018 will be a very busy year for the Chinese space program!
One of the hallmarks of the modern space age is the way in which emerging powers are taking part like never before. This of course includes China, whose presence in space has mirrored their rise in terms of global affairs. At the same time, the Indian Space Research Organization (IRSO), the European Space Agency, JAXA, the Canadian Space Agency, the South African Space Agency, and many others have been making their presence felt as well.
In short, space exploration is no longer the province of two major superpowers. And in the future, when crewed interplanetary missions and (fingers crossed!) the creation of colonies on other planets becomes a reality, it will likely entail a huge degree of international cooperation and public-private partnerships.

The only thing cooler than sending a helicopter drone to explore Titan is sending a nuclear powered one to do the job. Called the “Dragonfly” spacecraft, this helicopter drone mission has been selected as one of two finalists for NASA’s robotic exploration missions planned for the mid 2020’s. NASA selected the Dragonfly mission from 12 proposals they were considering under their New Horizons program.
Titan is Saturn’s largest moon, and is a primary target in the search for life in our Solar System. Titan has liquid hydrocarbon lakes on its surface, a carbon-rich chemistry, and sub-surface oceans. Titan also cycles methane the way Earth cycles water.
This true-color image of Titan, taken by the Cassini spacecraft, shows the moon’s thick, hazy atmosphere. Image: By NASA – http://photojournal.jpl.nasa.gov/catalog/PIA14602, Public Domain, https://commons.wikimedia.org/w/index.php?curid=44822294
Dragonfly would fulfill its mission by hopping around on the surface of Titan. Once an initial landing site is selected on Titan, Dragonfly will land there with the assistance of a ‘chute. Dragonfly will spend periods of time on the ground, where it will charge its batteries with its radioisotope thermoelectric generator. Once charged, it would then fly for hours at time, travelling tens of kilometers during each flight. Titan’s dense atmosphere and low gravity (compared to Earth) allows for this type of mission.
During these individual flights, potential landing sites would be identified for further scientific work. Dragonfly will return to its initial landing site, and only visit other sites once they have been verified as safe.
Dragonfly is being developed at the Johns Hopkins Applied Physics Laboratory (JHAPL.) It has a preliminary design weight of 450 kg. It’s a double quad-copter design, with four sets of dual rotors.
“Titan is a fascinating ocean world,” said APL’s Elizabeth Turtle, principal investigator for Dragonfly. “It’s the only moon in the solar system with a dense atmosphere, weather, clouds, rain, and liquid lakes and seas—and those liquids are ethane and methane. There’s so much amazing science and discovery to be done on Titan, and the entire Dragonfly team and our partners are thrilled to begin the next phase of concept development.”
The science objectives of the Dragonfly mission center around prebiotic organic chemistry and habitability on Titan. It will likely have four instruments:
Being chosen as a finalist has the team behind Dragonfly excited for the project. “This brings us one step closer to launching a bold and very exciting space exploration mission to Titan,” said APL Director Ralph Semmel. “We are grateful for the opportunity to further develop our New Frontiers proposals and excited about the impact these NASA missions will have for the world.”
Exploring Titan holds a daunting set of challenges. But as we’ve seen in recent years, NASA and its partners have the capability to meet those challenges. The JHAPL team behind Dragonfly also designed and built the New Horizons mission to Pluto and the Kuiper Belt object 2014 MU69. Their track record of success has everyone excited about the Dragonfly mission.
The Dragonfly mission, and the other finalist—the Comet Astrobiology Exploration Sample Return being developed by Cornell University and the Goddard Space Flight Center—will each receive funding through the end of 2018 to work on the concepts. In the Spring of 2019, NASA will select one of them and will fund its continued development.
Dragonfly is part of NASA’s New Frontiers program. New Frontiers missions are planetary science missions with a cap of approximately $850 million. New Frontiers missions include the Juno mission to Jupiter, the Osiris-REx asteroid sample-return missions, and the aforementioned New Horizons mission to Pluto.
Artist's impression of the Opportunity Rover, part of NASA's Mars Exploration Program. NASA/JPL-Caltech
When the Opportunity rover landed on Mars on January 25th, 2004, its mission was only meant to last for about 90 Earth days. But the little rover that could has exceeded all expectations by remaining in operation (as of the writing of this article) for a total of 13 years and 231 days and traveled a total of about 50 km (28 mi). Basically, Opportunity has continued to remain mobile and gather scientific data 50 times longer than its designated lifespan.
And according to a recent announcement from NASA’s Mars Exploration Program (MEP), the rover managed to survive yet another winter on Mars. Having endured the its eight Martian winter in a row, and with its solar panels in encouragingly clean condition, the rover will be in good shape for the coming dust-storm season. It also means the rover will live to see its 14th anniversary, which will take place on January 25th, 2018.
On Mars, a single year lasts the equivalent of 686.971 Earth days (or 1.88 Earth years). And since Mars’ axis is inclined 25.19° to its orbital plane (compared to Earth’s axial tilt of just over 23°), Mars also experiences seasons. However, these tend to last about twice as long as the seasons on Earth. And of course, the seasons on Mars’ are also much colder, with temperatures averaging about -63 °C (-82°F).

As Jennifer Herman, the power subsystem operations team lead for Opportunity at NASA’s Jet Propulsion Laboratory, recalled in a NASA MEP press statement:
“I didn’t start working on this project until about Sol 300, and I was told not to get too settled in because Spirit and Opportunity probably wouldn’t make it through that first Martian winter. Now, Opportunity has made it through the worst part of its eighth Martian winter.”
At present, both the Opportunity and Spirit rover are in Mars’ southern hemisphere. Here, the Sun appears in the northern sky during the fall and winter, so the rovers need to tilt their solar-arrays northward. Back in 2004, the Spirit rover had lost the use of two of its wheels, and could therefore not maneuver out of a sand trap it had become stuck in. As such, it was unable to tilt itself northward and did not survive its fourth Martian winter (in 2009).
However, Opportunity’s current position – Perseverance Valley, a fluid-carved region on the inner slope at the edge of the Endeavour Crater – meant that it was well-positioned to keep working through late fall and early winter this year. This was ensured by the stops the rover made at energy-favorable locations, where it would inspect local rocks, examine the valley’s shape and image the surrounding area, all the while absorbing ample energy from the Sun.

Five months ago, the rover entered the top of the valley, which runs eastward down the inner slope of the Endurance Crater’s western rim. Since that time, Opportunity has been conducting stops between drives at north-facing sites, which are situated along the southern edge of the channel. The rover team calls the sites “lily pads”, since these places are spots that the rover need to hop across during its mission.
This is necessary, given that Opportunity does not rely on a radioisotope thermoelectric generator like Curiosity does. While winter conditions affect the use of electrical heaters and batteries on both rovers, Opportunity is different in that it’s activities are more subject to seasonal change. Whereas Curiosity will simply allocate less energy to performing tasks in the winter, Opportunity needs to pick its routes to ensure it stays powered up.
During some of its previous winters, the Opportunity rover was not as well-situated as it currently is. During its fifth winter (2011-2012) the rover spent 19 weeks at one spot because no other places that allowed for a northward-facing tilt were available within driving distance. On the other hand, its first winter (2004-2005) was spent in the southern half of the Endurance Crater, where all grounds are favorable since they face north.
As the person who is chiefly responsible for advising other mission scientists on how much energy Opportunity has available on each Martian day (sol) for conducting activities like driving and observing – a task she performs for Curiosity as well – Herman understand the relationship between power usage and the seasons all too well. “Relying on solar energy for Opportunity keeps us constantly aware of the season on Mars and the terrain that the rover is on, more than for Curiosity,” she said.

Another factor which can influence Opportunity‘s power supply is how much dust is in the sky and how much of it gets onto the rover’s solar arrays. This is highly-dependent on prevailing wind conditions, which can both stir up dust storms and clear away dust deposits on the rover – basically, they are a real mixed blessing! During autumn and winter in the southern-hemisphere, the skies are generally clear where Opportunity operates.
Spring and summer is when the storms are most common in Mars’ southern hemisphere, though they don’t happen every year. The latest example took place in 2007, which led to a severe reduction in the amount of sunlight (and hence, solar energy) Spirit and Opportunity were able to receive. This required both rovers to enact emergency protocols and reduce the amount of operations and communications they conducted.
The amount of dust on the rover’s solar arrays going into autumn can also vary from year to year. This year, the array was dustier than in all but one of the previous Martian autumns it experienced. Luckily, as Herman explained, things worked out for the rover:
“We were worried that the dust accumulation this winter would be similar to some of the worst winters we’ve had, and that we might come out of the winter with a very dusty array, but we’ve had some recent dust cleaning that was nice to see. Now I’m more optimistic. If Opportunity’s solar arrays keep getting cleaned as they have recently, she’ll be in a good position to survive a major dust storm. It’s been more than 10 Earth years since the last one and we need to be vigilant.”

In the coming months, the Opportunity team hopes to investigate how the Perseverance Valley was cut into the rim of the Endeavor crater. As Matt Golombek, an Opportunity Project Scientist at JPL, related:
“We have not been seeing anything screamingly diagnostic, in the valley itself, about how much water was involved in the flow. We may get good diagnostic clues from the deposits at the bottom of the valley, but we don’t want to be there yet, because that’s level ground with no more lily pads.”
With its eighth winter finished and Opportunity still in good working order, we can expect the tenacious rover to keep turning up interesting finds on Mars. These include clues about Mars’ warmer, wetter past, which likely included a standing body of water in the Endeavor crater. And assuming conditions are favorable in the coming year, we can expect that Opportunity will continue to push the boundaries of both science and its own endurance!

Soon thereafter at 5:04 a.m., Expedition 53 Flight Engineer Paolo Nespoli of ESA (European Space Agency) assisted by NASA astronaut Randy Bresnik successfully captured Orbital ATK’s Cygnus cargo freighter using the International Space Station’s 57.7-foot-long (17.6 meter-long) Canadarm2 robotic arm.
The station was orbiting 260 statute miles over the South Indian Ocean at the moment Nespoli grappled the S.S. Gene Cernan Cygnus spacecraft with the Canadian-built robotic arm.
Nespoli and Bresnik were working at a robotics work station inside the seven windowed domed Cupola module that offers astronauts the most expansive view outside to snare Cygnus with the robotic arms end effector.
The Cygnus cargo freighter – named after the last man to walk on the Moon – reached its preliminary orbit nine minutes after blasting off early Sunday atop the upgraded 230 version of the Orbital ATK Antares rocket from NASA’s Wallops Flight Facility in Virginia.
The flawless liftoff of the two stage Antares rocket took place shortly after sunrise Sunday at 7:19 a.m. EST, Nov. 12, rocket from Pad-0A at NASA’s Wallops Flight Facility in Virginia.

Sunday’s spectacular Antares launch delighted spectators – but came a day late due to a last moment scrub on the originally planned Veteran’s Day liftoff, Saturday, Nov. 11, when a completely reckless pilot flew below radar into restricted airspace just 5 miles away from the launch pad – forcing a sudden and unexpected halt to the countdown under absolutely perfect weather conditions.
After a carefully choreographed series of intricate thruster firings to raise its orbit over the next two days, the Cygnus spacecraft on the OA-8 resupply mission for NASA arrived in the vicinity of the orbiting research laboratory.
With Cygnus firmly in the grip of the robots hand, ground controllers at NASA’s Mission Control at the Johnson Space Center in Texas, maneuvered the arm towards the exterior hull and berth the cargo ship at the Earth-facing port of the stations Unity module.
1st stage capture was completed at 7:08 a. EST Nov 14.
After driving in the second stage gang of bolts, hard mate and capture were completed at 7:15 a.m.
The station was flying 252 miles over the North Pacific in orbital night at the time of berthing.
The Cygnus spacecraft dubbed OA-8 is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing and reliable basis.
NASA TV provided live coverage of the rendezvous and grappling.
Including Cygnus there are now five visiting vehicle spaceships parked at the space station including also the Russian Progress 67 and 68 resupply ships and the Russian Soyuz MS-05 and MS-06 crew ships.

Cygnus will remain at the space station until Dec. 4, when the spacecraft will depart the station and deploy several CubeSats before its fiery re-entry into Earth’s atmosphere as it disposes of several tons of trash.
On this flight, the Cygnus OA-8 spacecraft is jam packed with its heaviest cargo load to date!
Altogether over 7,400 pounds of science and research, crew supplies and vehicle hardware launched to the orbital laboratory and its crew of six for investigations that will occur during Expeditions 53 and 54.
The S.S. Gene Cernan manifest includes equipment and samples for dozens of scientific investigations including those that will study communication and navigation, microbiology, animal biology and plant biology. The ISS science program supports over 300 ongoing research investigations.
Among the experiments flying aboard Cygnus are the coli AntiMicrobial Satellite (EcAMSat) mission, which will investigate the effect of microgravity on the antibiotic resistance of E. coli, the Optical Communications and Sensor Demonstration (OCSD) project, which will study high-speed optical transmission of data and small spacecraft proximity operations, the Rodent Research 6 habitat for mousetronauts who will fly on a future SpaceX cargo Dragon.
Cernan was commander of Apollo 17, NASA’s last lunar landing mission and passed away in January at age 82. He set records for both lunar surface extravehicular activities and the longest time in lunar orbit on Apollo 10 and Apollo 17.
The prime crew for the Apollo 17 lunar landing mission are: Commander, Eugene A. Cernan (seated), Command Module pilot Ronald E. Evans (standing on right), and Lunar Module pilot, Harrison H. Schmitt (left). They are photographed with a Lunar Roving Vehicle (LRV) trainer. Cernan and Schmitt used an LRV during their exploration of the Taurus-Littrow landing site.

Under the Commercial Resupply Services-1 (CRS-1) contract with NASA, Orbital ATK will deliver approximately 66,000 pounds (30,000 kilograms) of cargo to the space station. OA-8 is the eighth of these missions.
The Cygnus OA-8 spacecraft is Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station under the unmanned Commercial Resupply Services (CRS) program to stock the station with supplies on a continuing basis.
Beginning in 2019, the company will carry out a minimum of six cargo missions under NASA’s CRS-2 contract using a more advanced version of Cygnus.

The weather on Venus is like something out of Dante’s Inferno. The average surface temperature – 737 K (462 °C; 864 °F) – is hot enough to melt lead and the atmospheric pressure is 92 times that of Earth’s at sea level (9.2 MPa). For this reason, very few robotic missions have ever made it to the surface of Venus, and those that have did not last long – ranging from about 20 minutes to just over two hours.
Hence why NASA, with an eye to future missions, is looking to create robotic missions and components that can survive inside Venus’ atmosphere for prolonged periods of time. These include the next-generation electronics that researchers from NASA Glenn Research Center (GRC) recently unveiled. These electronics would allow a lander to explore Venus surface for weeks, months, or even years.
In the past, landers developed by the Soviets and NASA to explore Venus – as part of the Venera and Mariner programs, respectively – relied on standard electronics, which were based on silicon semiconductors. These are simply not capable of operating in the temperature and pressure conditions that exist on the surface of Venus, and therefore required that they have protective casings and cooling systems.
Naturally, it was only a matter of time before these protections failed and the probes stopped transmitting. The record was achieved by the Soviets with their Venera 13 probe, which transmitted for 127 minutes between its descent and landing. Looking ahead, NASA and other space agencies want to develop probes that can gather as much information as they can on Venus’s atmosphere, surface, and geological history before they time out.
To do this, a team from NASA’s GRC has been working to develop electronics that rely on silcon carbide (SiC) semiconductors, which would be capable of operating at or above Venus’ temperatures. Recently, the team conducted a demonstration using the world’s first moderately-complex SiC-based microcircuits, which consisted of tens or more transistors in the form of core digital logic circuits and analog operation amplifiers.
These circuits, which would be used throughout the electronic systems of a future mission, were able to operate for up to 4000 hours at temperatures of 500 °C (932 °F) – effectively demonstrated that they could survive in Venus-like conditions for prolonged periods. These tests took place in the Glenn Extreme Environments Rig (GEER), which simulated Venus’ surface conditions, including both the extreme temperature and high pressure.
Back in April of 2016, the GRC team tested a SiC 12-transistor ring oscillator using the GEER for a period of 521 hours (21.7 days). During the test, they raised they subjected the circuits to temperatures of up to 460 °C (860 °F), atmospheric pressures of 9.3 MPa and supercritical levels of CO² (and other trace gases). Throughout the entire process, the SiC oscillator showed good stability and kept functioning.

This test was ended after 21 days due to scheduling reasons, and could have gone on much longer. Nevertheless, the duration constituted a significant world record, being orders of magnitude longer than any other demonstration or mission that has been conducted. Similar tests have shown that ring oscillator circuits can survive for thousands of hours at temperatures of 500 °C (932 °F) in Earth-air ambient conditions.
Such electronics constitute a major shift for NASA and space exploration, and would enable missions that were previously impossible. NASA’s Science Mission Direction (SMD) plans to incorporate SiC electronics on their Long-Life In-situ Solar System Explorer (LLISSE). A prototype is currently being developed for this low-cost concept, which would provide basic, but highly valuable scientific measures from the surface of Venus for months or longer.
Other plans to build a survivable Venus explorer include the Automaton Rover for Extreme Environments (AREE), a “steampunk rover” concept that relies on analog components rather than complex electronic systems. Whereas this concepts seeks to do away with electronics entirely to ensure a Venus mission could operate indefinitely, the new SiC electronics would allow more complex rovers to continue operating in extreme conditions.
Beyond Venus, this new technology could also lead to new classes of probes capable of exploring within gas giants – i.e. Jupiter, Saturn, Uranus and Neptune – where temperature and pressure conditions have been prohibitive in the past. But a probe that relies on a hardened shell and SiC electronic circuits could very well penetrate deep into the interior of these planets and reveal startling new things about their atmospheres and magnetic fields.

The surface of Mercury could also be accessible to rovers and landers using this new technology – even the day-side, where temperatures reach a high of 700 K (427 °C; 800 °F). Here on Earth, there are plenty of extreme environments that could now be explored with the help of SiC circuits. For example, drones equipped with SiC electronics could monitor deep-sea oil drilling or explore deep into the Earth’s interior.
There are also commercial applications involving aeronautical engines and industrial processors, where extreme heat or pressure traditionally made electronic monitoring impossible. Now such systems could be made “smart”, where they are capable of monitoring themselves instead of relying on operators or human oversight.
With extreme circuits and (someday) extreme materials, just about any environment could be explored. Maybe even the interior of a star!

PORT CANAVERAL/KENNEDY SPACE CENTER, FL – ‘The SpaceX boosters back in town! The boosters back in town!’ paraphrasing the popular lyrics of the hit single from Irish hard rock band Thin Lizzy – its what comes to mind with the speedy cadence of ‘launch, land and relaunch’ firmly established by CEO Elon Musk’s hard rocking crew of mostly youthful rocket scientists and engineers.
Barely three days after successfully launching the commercial KoreaSat-5A telecomsat on Monday Oct 30, the SpaceX Falcon 9 first stage booster that did the heavy lifting to orbit generating 1.7 million pounds of liftoff thrust – arrived back in town Thursday, Nov. 2 or more specifically back into Port Canaveral, Florida.
“Guess who’s back in town?” – the song continues – well its the Falcon 9 that reached the edge of space on Halloween Eve while traveling several thousand miles per hour, flipped around like a witches broom and carried out a pinpoint propulsive and upright touchdown of what amounts to a stick on a board in the middle of the Atlantic Ocean. Just amazing!
Floating atop the football field sized platform upon which it soft landed 8.5 minutes after the two stage Falcon 9 lifted off at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The 16 story tall booster arrived back into the mouth of Port Canaveral late Thursday at sunset – as witnessed up close by myself and several space journalist colleagues.
Check out our expanding photo and video gallery compiled here of the boosters arrival into Port on the OCISLY droneship. The gallery is growing so check back again for more up close looks of the ocean arrival, sailing and docking.

Furthermore the four landing legs that made the landing sequence possible – have already been quickly detached by workers this afternoon, as shown here with additional incredible up close imagery.

Plus also featured are lots of imagery of the booster sailing through the narrow channel of Port Canaveral – often past seemingly oblivious spectators and pleasure craft who have no idea what they are seeing. As well as imagery of work crews processing the booster for the eventual return back onto base.

The 156 foot-tall first stage atop OCISLY was towed from the Atlantic Ocean landing zone located several hundred miles off shore of the Florida’s East coast back into Port Canaveral by a tugboat named “Hawk.”
The Hawk was accompanied by a small naval flotilla of commercial vessels SpaceX leased for the occasion.

In fact with each booster return the SpaceX technicians are progressing faster and faster carrying out the booster processing involving safing, cap and line attachment, leg removal, and lowering the booster for horizontal placement on a specially outfitted lengthy multi-wheeled trailer for hauling back to SpaceX hangar facilities on the Kennedy Space Center and Cape Canaveral Air Force Station.

After arriving in port, and sailing through the channel for about 45 minutes the SpaceX flotilla carefully and methodically edged the droneship closer to shore and docked the vessel last night – and the crews got a well deserved rest as the booster basked in the maritime glow producing beautiful water reflection vistas.

The team wasted no time this morning. At the crack of dawn they began the task of attaching a hoisting cap to the top of the first stage.
Shortly after 9 a.m. EDT they craned the booster off OCISLY and onto a restraining pedestal platform on land.
The techs were working fast and making mincemeat of the booster.
They detached the four insect like legs one after another in an operation that looked a lot like a well thought out dissection.
One at a fime over a period about roughly two hour the workers methodically unbolted and detached the legs in 2 pieces. First they they slung a harness around the upper strut and removed it with a small crane. Then they did the same with the lower foot pad.
Altogether the land leg amputation operation took about 2.5 hours.
The now legless Falcon 9 stands erect. It will soon be lowered and placed horizontally for transport back to the base.

It has been barely two weeks after the last dogeship landed booster arrived back into port in mid-October for the SES-11 launch on October 11 and sunrise port arrival on October 15.
OCISLY which stands for “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 30 launch and was prepositioned in the Atlantic Ocean several hundred miles (km) off the US East coast, awaiting the boosters approach and pinpoint propulsive soft landing.
The booster was outfitted with four grid fins and four landing legs to accomplish the pinpoint touchdown on the barge at sea.
