For generations, human beings have fantasized about the possibility of finding extra-terrestrial life. And with our ongoing research efforts to discover new and exciting extrasolar planets (aka. exoplanets) in distant star systems, the possibility of actually visiting one of these worlds has received a real shot in the arm. Unfortunately, given the astronomical distances involved, not to mention the cost of mounting an expedition, doing so presents numerous significant challenges.
However, Russian billionaire Yuri Milner and the Breakthrough Foundation – an international organization committed to exploration and scientific research – is determined to mount an interstellar mission to Alpha Centauri, our closest stellar neighbor, in the coming years. With the backing of such big name sponsors as Mark Zuckerberg and Stephen Hawking, his latest initiative (named “Project Starshot“) aims to send a tiny spacecraft to the Alpha Centauri system to search for planets and signs of life.
SpaceX has released a slew of up close photos showing the sensational “super smooth” touchdown last week of a Falcon 9 booster on a tiny droneship at sea located several hundred miles (km) off the East coast of Florida.
“This time it really went super smooth,” Hans Koenigsmann, SpaceX VP of Flight Reliability, told Universe Today at the NorthEast Astronomy and Space Forum (NEAF) held in Suffern, NY. “The rest is history almost.”
The dramatic propulsive descent and soft landing of the SpaceX Falcon 9 first stage took place last Friday, April 8 about 9 minutes after blasting off from Cape Canaveral Air Force Station at 4:43 p.m. EDT on the Dragon CRS-8 resupply mission for NASA to the International Space Station (ISS).
The breathtaking new photos show the boosters central Merlin 1D engine refiring to propulsively slow the first stage descent with all four landing legs unfurled and locked in place at the bottom and all four grid fins deployed at the top.
Why did it all go so well, comparing this landing to the prior attempts? Basically the return trajectory was less challenging due to the nature of the NASA payload and launch trajectory.
“We were more confident about this droneship landing,” Koenigsmann said at NEAF.
“I knew the trajectory we had [for CRS-8] was more benign, although not super benign. But certainly benigner than for what we had before on the SES-9 mission, the previous one. The [droneship] landing trajectory we had for the previous one on SES-9 was really challenging.”
“This one was relatively benign. It was really maybe as benign as for the Orbcomm launch [in December 2015] where we had the land landing.”
The diminutive ocean landing platform measures only about 170 ft × 300 ft (52 m × 91 m). SpaceX formally dubs it an ‘Autonomous Spaceport Drone Ship’ or ASDS.
The ocean going ship is named “Of Course I Still Love You” after a starship from a novel written by Iain M. Banks.
It was stationed some 200 miles off shore of Cape Canaveral, Florida surrounded by the vastness of the Atlantic Ocean.
“The CRS-8 launch was one of the easiest ones we ever had.”
The revolutionary rocket recovery event counts as the first successful droneship landing of a rocket in history and is paving the way towards eventual rocket recycling aimed at dramatically slashing the cost of access to space.
The final moments of the 15 story tall boosters approach and hover landing was captured up close in stunning high resolution imagery recorded by multiple remote cameras set up right on the ocean going platform by SpaceX photographer Ben Cooper.
Landing the booster on land rather than at sea was actually an option this time around. But SpaceX managers wanted to try and nail a platform at sea landing to learn more and validate their calculations and projections.
“As Elon Musk said at the post-landing press conference of Friday, we could have actually come back to land- to land this one on land,” Koenigsmann elaborated.
“But we decided to land on the drone ship first to make sure that on the droneship we had worked everything out!”
“And that’s exactly what happened. So I felt this was only going out a little bit on the limb,” but not too much.”
Before the CRS-8 launch, Koenigsmann had rated the chances of a successful landing recovery rather high.
Three previous attempts by SpaceX to land on a droneship at sea were partially successful, as the stage made a pinpoint flyback to the tiny droneship, but it either hit too hard or tipped over in the final moments when a landing leg failed to fully deploy or lock in place.
“Everything went perfect with the launch,” Koengismann said. “We just still have to do the post launch data review.”
“I am really glad this went well.”
This recovered Falcon 9 booster finally arrived back into Port Canaveral, Florida four days later in the early morning hours of Tuesday, April 12 at about 1:30 a.m. EDT.
The primary goal of the Falcon 9 launch on April 8 was carrying the SpaceX Dragon CRS-8 cargo freighter to low Earth orbit on a commercial resupply delivery mission for NASA to the International Space Station (ISS).
Dragon arrived at the station on Sunday, April 10, loaded with 3 tons of supplies, science experiments and the BEAM experimental expandable module.
Landing on the barge was a secondary goal of SpaceX and not part of the primary mission for NASA.

The recovered booster will be cleaned and defueled, says SpaceX spokesman John Taylor.
SpaceX engineers will conduct a series of 12 test firings to ensure all is well operationally and that the booster can be re-launched.
SpaceX hopes to refly the recovered booster in a few months, perhaps as early as this summer.

Even if we beat global warming, and survive long enough to face and survive the next ice age, Earth will still die. Even if we build a peaceful civilization, protect the planet from asteroids, fight off mutant plagues and whatever else comes our way, life on Earth will die. No matter what we do, the Sun will reach the end of its life, and render Earth uninhabitable.
So reaching for the stars is imperative. What sounds unrealistic to a great many people is a matter of practicality for people knowledgeable about space. To survive, we must have more than Earth.
A project launched by billionaire Yuri Milner, and backed by Mark Zuckerberg, intends to send tiny spacecraft to our nearest stellar neighbour, the Alpha Centauri system. With an expert group assembled to gauge the feasibility, and with the support of eminent cosmologist Stephen Hawking, this idea is gaining traction.
The distance to the Centauri system is enormous: 4.3 light years, or 1.34 parsecs. The project plans to use lasers to propel the craft, which should mean the travel time would be approximately 30 years, rather than the 30,000 year travel time that current technology restricts us to.
Of course, there are still many technological hurdles to overcome. The laser propulsion system itself is still only a nascent idea. But theoretically it’s pretty sound, and if it can be mastered, should be able to propel space vehicles at close to relativistic speeds.
There are other challenges, of course. The tiny craft will need robust solar sails as part of the propulsion system. And any instruments and cameras would have to be miniaturized, as would any communication equipment to send data back to Earth. But in case you haven’t been paying attention, humans have a pretty good track record of miniaturizing electronics.
Though the craft proposed are tiny, no larger than a microchip, getting them to the Alpha Centauri system is a huge step. Who knows what we’ll learn? But if we’re ever to explore another solar system, it has to start somewhere. And since astronomers think it’s possible that the Centauri system could have potentially habitable planets, it’s a great place to start.
The SpaceX Falcon 9 that triumphantly accomplished history’s first upright landing of the spent first stage of a rocket on a barge at sea – after launching a critical cargo payload to orbit for NASA – sailed back into port at Cape Canaveral overnight in the wee hours of this morning, April 12, standing tall.
The recovered 15 story tall Falcon 9 booster arrived back into Port Canaveral, Florida at about 130 a.m. early today, towed atop the ocean going platform that SpaceX dubs an ‘Autonomous Spaceport Drone Ship’ or ASDS.
The ship is named “Of Course I Still Love You” after a starship from a novel written by Iain M. Banks. The landing platform measures only about 170 ft × 300 ft (52 m × 91 m).
A small crowd of excited onlookers and space photographers savored and cheered the incredible moment that is surely changing the face and future of space exploration and travel.
The two stage SpaceX Falcon 9 rocket boasting over 1.5 million pounds of thrust originally launched on Friday, April 8 at 4:43 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The primary goal of the Falcon 9 launch was carrying the SpaceX Dragon CRS-8 cargo freighter to low Earth orbit on a commercial resupply delivery mission for NASA to the International Space Station (ISS).
Before the launch, SpaceX managers rated the chances of a successful landing recovery rather high.
Three previous attempts by SpaceX to land on a barge at sea were partially successful, as the stage made a pinpoint flyback to the tiny ship but either hit too hard or tipped over in the final moments when a landing leg failed to fully deploy or lock in place.
“We were very optimistic of the chances of a successful landing on this mission,” Hans Koenigsmann told Universe Today in an exclusive post landing interview at the NorthEast Astronomy and Space Forum (NEAF) held in Suffern, NY.
Coincidentally, today marks two major anniversaries in the history of space flight; the 55th anniversary of the launch of Russia’s Yuri Gagarin, the first man in space on Vostok-1 on April 12, 1961; and the 35th anniversary of the launch of shuttle Columbia on America’s first space shuttle mission (STS-1) on April 12, 1981 with John Young and Bob Crippen.
The vision of SpaceX’s billionaire founder and CEO Elon Musk is to dramatically slash the cost of access to space by recovering the firms rockets and recycling them for reuse – so that launching rockets will one day be nearly as routine and cost effective as flying on an airplane.
The stage will now be painstakingly inspected, tested and refurbished.
The essential next step after recovery is recycling. Musk said he hopes to re-launch the booster this year.
At liftoff, Dragon was loaded with over 3.5 tons of research experiments and essential supplies for the six man crew living aboard the orbiting science complex.

The Dragon CRS-8 cargo ship successfully arrived at the station on Sunday, April 10 and was joined to the million pound station at the Earth-facing port of the Harmony module.
The secondary objective was to try and land the Falcon 9 first stage on the ASDS done ship located some 200 miles off shore in the Atlantic Ocean.
The action-packed and propulsive landing took place some 10 minutes after liftoff.
In the final moments of the descent to the drone ship, one of the first stage Merlin 1D engines was reignited to slow the boosters descent speed as the quartet of side-mounted landing legs at the boosters base were unfurled, deployed and locked into place.
The entire launch and landing sequence was webcast live on NASA TV and by SpaceX.
The recovered booster atop the “Of Course I Still Love You” barge was towed back to port by the Elsbeth III tug.
“Home sweet home”, said my friend and veteran space photographer Julian Leek, who witnessed the boosters arrival back in port overnight.
“It was really a sight to see. Pilots and tugs did a well coordinated job to bring her in.”
After daylight dawned, a crane lifted the recovered booster into a storage cradle where it will remain upright for a few days. Then it will be lowered and placed horizontally for transport a few miles north to a SpaceX processing hanger back at pad 39A at the Kennedy Space Center.
The booster will be cleaned and defueled, SpaceX spokesman John Taylor told the media.
SpaceX engineers will conduct a series of 12 test firings to ensure all is well operationally and that the booster can be re-launched.

The U.S. SpaceX Dragon cargo craft arrived at the ISS following a carefully choreographed orbital chase inaugurated by a spectacular launch atop an upgraded SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station, Florida, on Friday, April 8.
As the massive Earth orbiting outpost was soaring some 250 miles (400 kilometers) over the Pacific Ocean west of Hawaii, British astronaut Tim Peake of ESA (European Space Agency), with the able assistance of NASA’s Jeff Williams, successfully captured the SpaceX Dragon CRS-8 resupply ship with the station’s Canadian-built robotic arm.
Peake painstakingly maneuvered and deftly grappled Dragon with the snares at the terminus of the 57 foot long (19 meter long) Canadarm2 at 7:23 a.m. EDT for installation on the million pound orbital lab complex.
“Looks like we’ve caught a Dragon,” Peake radioed back to Mission Control. The orbital operational was webcast live on NASA TV.
“Awesome capture by crewmate Tim Peake,” said fellow NASA crewmate Tim Kopra who snapped a series of breathtaking images of the approach and capture.
Ground controllers at Mission Control in Houston then issued commands to carefully guide the robotic arm holding the Dragon freighter to the Earth-facing port on the bottom side of the Harmony module for its month long stay at the space station.
The ship was finally bolted into place at 9:57 a.m. EDT as the station flew 250 miles (400 km) over southern Algeria.

Expedition 47 crew members Jeff Williams and Tim Kopra of NASA, Tim Peake of ESA (European Space Agency) and cosmonauts Yuri Malenchenko, Alexey Ovchinin and Oleg Skripochka of Roscosmos are currently living aboard the orbiting laboratory.
In a historic first, the arrival of the SpaceX Dragon cargo spacecraft marks the first time that two American cargo ships are simultaneously docked to the ISS. The Orbital ATK Cygnus CRS-6 cargo freighter only just arrived on March 26 and is now installed at a neighboring docking port on the Unity module.
Cygnus was launched to the ISS atop a ULA Atlas V barely two weeks earlier on March 22 – as I reported on and witnessed from the Kennedy Space Center press site.
“With the arrival of Dragon, the space station ties the record for most vehicles on station at one time – six,” say NASA officials.
The Dragon spacecraft is delivering almost 7,000 pounds of cargo, including the Bigelow Expandable Activity Module (BEAM), to the orbital laboratory which was carried to orbit inside the Dragon’s unpressurized truck section.
BEAM is a prototype inflatable habitat that the crew will soon pluck from the Dragon’s truck with the robotic arm for installation on a side port of the Harmony module.
CRS-8 counts as the company’s eighth flight to deliver supplies, science experiments and technology demonstrations to the ISS for the crews of Expeditions 47 and 48 to support dozens of the approximately 250 science and research investigations in progress.
Friday’s launch marks the first for a Dragon since the catastrophic failure of the SpaceX Falcon 9 last June.
Dragon will remain at the station until it returns for Earth on May 11 for a parachute assisted splash down in the Pacific Ocean off the west coast of Baja California. It will be packed with almost 3,500 pounds off cargo and numerous science samples, including those biological samples collected by 1 year ISS crew member Scott Kelly, for return to investigators, hardware and spacewalking tools, some additional broken hardware for repair and some items of trash for disposal.

All around, today, April 8, was a great day for the future of space exploration. SpaceX successfully restarted their critical cargo flights for NASA to stock the International Space Station (ISS) with essential supplies and groundbreaking science experiments, while the innovative firm also successfully landed the first stage of their Falcon 9 rocket on a barge at sea.
The triumphant ‘Return to Flight’ launch of the upgraded SpaceX Falcon 9 with the Dragon CRS-8 cargo freighter was the primary goal of Friday’s launch and validated the hardware fixes put in place following the catastrophic failure of the previous Dragon CRS-7 cargo ship two minutes after liftoff on June 28, 2015 due to a faulty strut in the boosters second stage.
Landing the booster safely on a drone ship at sea was the secondary goal of the flight but is critical towards achieving the vision of rocket recovery and reusability at the heart of SpaceX Founder Elon Musk’s dream of slashing the cost of access to space and one day establishing a ‘City on Mars.”
The weather was fantastic in the sunshine state as the two stage SpaceX Falcon 9 rocket boasting over 1.3 million pounds of thrust launched on time Friday at 4:43 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The Dragon spacecraft is delivering almost 7,000 pounds of cargo, including the Bigelow Expandable Activity Module (BEAM), to the orbital laboratory.
Friday’s launch marks the first for a Dragon since the catastrophic failure of the SpaceX Falcon 9 last June.
CRS-8 counts as the company’s eighth flight to deliver supplies, science experiments and technology demonstrations to the ISS for the crews of Expeditions 47 and 48 to support dozens of the approximately 250 science and research investigations in progress.
Packed aboard the Dragon’s unpressurized trunk section is the experimental Bigelow Expandable Activity Module (BEAM) – an experimental expandable capsule that the crew will attach to the space station. The 3115 pound (1413 kg) BEAM will test the use of an expandable space habitat in microgravity. BEAM will expand to roughly 13-feet-long and 10.5 feet in diameter after it is installed.
Among the new experiments arriving to the station will be Veggie-3 to grow Chinese lettuce in microgravity as a followup to Zinnias recently grown, an investigation to study muscle atrophy and bone loss in space, using microgravity to seek insight into the interactions of particle flows at the nanoscale level and use protein crystal growth in microgravity to help in the design of new drugs to fight disease, as well as reflight of 25 student experiments from Student Spaceflight Experiments Program (SSEP) Odyssey II payload that were lost during the CRS-7 launch failure.
“The cargo will allow investigators to use microgravity conditions to test the viability of expandable space habitats, assess the impact of antibodies on muscle wasting, use protein crystal growth to aid the design of new disease-fighting drugs and investigate how microbes could affect the health of the crew and their equipment over a long duration mission,” said NASA Deputy Administrator Dava Newman.
Dragon reached its preliminary orbit about 10 minutes after launch and deployed its solar arrays as targeted and as seen on the live webcast. It now begins a carefully choreographed series of thruster firings to reach the space station.
After a 2 day orbital chase Dragon is set to arrive at the orbiting outpost on Sunday, April 10.
NASA astronaut Jeff Williams and ESA (European Space Agency) astronaut Tim Peake will then reach out with the station’s Canadian-built robotic arm to grapple and capture the Dragon spacecraft.
Ground commands will be sent from Houston to the station’s arm to install Dragon on the Earth-facing bottom side of the Harmony module for its stay at the space station. Live coverage of the rendezvous and capture will begin at 5:30 a.m. on NASA TV, with installation set to begin at 9:30 a.m.
In a historic first, the launch of a SpaceX Dragon cargo spacecraft sets the stage for the first time that two American cargo ships will be simultaneously attached to the ISS.

The SpaceX Dragon is set for its ‘Return to Flight’ mission on Friday, April 8, packed with nearly 7000 pounds (3100 kg) of critical cargo and research experiments bound for the six-man crew working aboard the International Space Station.
Blastoff of the commercial SpaceX Falcon 9 carrying the Dragon CRS-8 resupply ship is slated for 4:43 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The weather outlook looks great with a forecast of 90 percent “GO” and extremely favorable conditions at launch time of the upgraded, full thrust version of the SpaceX Falcon 9. The only concern is for winds.
The SpaceX/Dragon CRS-8 launch coverage will be broadcast on NASA TV beginning at 3:30 p.m. EDT with additional commentary on the NASA launch blog.
SpaceX also features a live webcast approximately 20 minutes before launch beginning at 4:23 p.m. EDT.
The launch window is instantaneous, meaning that any delays due to weather or technical issues will results in a minimum 1 day postponement.
A backup launch opportunity exists on Saturday, April 9, at 4:20 p.m. with NASA TV coverage starting at 3:15 p.m.
SpaceX most recently launched the upgraded Falcon 9 from the Cape on March 4, 2016 as I reported from onsite here.
Friday’s launch marks the first for a Dragon since the catastrophic failure of a SpaceX Falcon 9 rocket in flight last year on June 28, 2015 on the CRS-7 resupply mission.

It’s time to whip out your 3-D glasses to enjoy and scrutinize the remarkable detail of spectacular terrain revealed in a new high resolution stereo image of Pluto – King of the Kuiper Belt! – taken by NASA’s New Horizons spacecraft.
The amazing new stereo Plutonian image focuses on an area dominated by a mysterious feature that geologists call ‘bladed’ terrain – seen above – and its unlike anything seen elsewhere in our solar system.
Its located in a broad region of rough highlands informally known as Tartarus Dorsa – situated to the east of the Pluto’s huge heart shaped feature called Tombaugh Regio. The best resolution is approximately 1,000 feet (310 meters).
The stereo view combines a pair of images captured by New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC) science instruments. They were taken about 14 minutes apart on during history making first ever flyby of the Pluto planetary system on July 14, 2015.
The first was taken when New Horizons was 16,000 miles (25,000 kilometers) away from Pluto, the second when the spacecraft was 10,000 miles (about 17,000 kilometers) away.
The blades align from north to south, typically reach up to about 550 yards (500 meters) high and are spaced about 2-4 miles (3-5 kilometers). Thus they are among the planets steepest features. They are “perched on a much broader set of rounded ridges that are separated by flat valley floors,” according to descriptions from the New Horizons science team.
Mission scientists have also noted that the bladed terrain has the texture of “snakeskin” owing to their “scaly raised relief.”
In the companion global image from NASA (below), the bladed terrain is outlined in red and shown to extend quite far to the east of Tombaugh Regio.
The composite image was taken on July 13, 2015, the day before the closest approach flyby, when the probe was farther away thus shows lower resolution. It combines a pair of images from two of the science instruments – a Ralph/Multispectral Visible Imaging Camera (MVIC) color scan and an image from the Long Range Reconnaissance Imager (LORRI).
The MVIC scan was taken from a range of 1 million miles (1.6 million kilometers), at a resolution of 20 miles (32 kilometers) per pixel. The corresponding LORRI image was obtained from roughly the same range, but has a higher spatial resolution of 5 miles (8 kilometers) per pixel, say officials.
Scientists have developed several possible theories about the origins of the bladed terrain, including erosion from evaporating ices or deposition of methane ices.
Measurements from the Linear Etalon Imaging Spectral Array (LEISA) instrument reveal that that this region “is composed of methane (CH4) ice with a smattering of water,” reports New Horizons researcher Orkan Umurhan.
He speculates that “the material making up the bladed terrain is a methane clathrate. A clathrate is a structure in which a primary molecular species (say water, or H2O) forms a crystalline ‘cage’ to contain a guest molecule (methane or CH4, for example).”
But the question of whether that methane ice is strong enough to maintain the steep walled snakeskin features, will take much more research to determine a conclusive answer.
Umurhan suggests that more research could help determine if the “methane clathrates in the icy moons of the outer solar system and also in the Kuiper Belt were formed way back before the solar system formed – i.e., within the protosolar nebula – potentially making them probably some of the oldest materials in our solar system.”
Pluto continues to amaze and surprise us as the data streams back to eagerly waiting scientists on Earth over many more months to come – followed by years and decades of painstaking analysis.
During New Horizons flyby on July 14, 2015, it discovered that Pluto is the biggest object in the outer solar system and thus the ‘King of the Kuiper Belt.”
The Kuiper Belt comprises the third and outermost region of worlds in our solar system.
Pluto is the last planet in our solar system to be visited in the initial reconnaissance of planets by spacecraft from Earth since the dawn of the Space Age.
New Horizons remains on target to fly by a second Kuiper Belt Object (KBO) on Jan. 1, 2019 – tentatively named PT1, for Potential Target 1. It is much smaller than Pluto and was recently selected based on images taken by NASA’s Hubble Space Telescope.

A “beautiful dust devil” was just discovered today, April 1, on the Red Planet by NASA’s long lived Opportunity rover as she is simultaneously exploring water altered rock outcrops at the steepest slopes ever targeted during her 13 year long expedition across the Martian surface. Opportunity is searching for minerals formed in ancient flows of water that will provide critical insight into establishing whether life ever existed on the fourth rock from the sun.
“Yes a beautiful dust devil on the floor of Endeavour Crater,” Ray Arvidson, Opportunity Deputy Principal Investigator of Washington University in St. Louis, confirmed to Universe Today. Spied from where “Opportunity is located on the southwest part of Knudsen Ridge” in Marathon Valley.
The new dust devil – a mini tornado like feature – is seen scooting across the ever fascinating Martian landscape in our new photo mosaic illustrating the steep walled terrain inside Marathon Valley and overlooking the crater floor as Opportunity makes wheel tracks at the current worksite on a crest at Knudsen Ridge. The colorized navcam camera mosaic combines raw images taken today on Sol 4332 (1 April 2016) and stitched by the imaging team of Ken Kremer and Marco Di Lorenzo.
“The dust devils have been kind to this rover,” Jim Green, Director of NASA Planetary Sciences at NASA HQ, said in an exclusive interview with Universe Today. They are associated with prior periods of solar array cleansing power boosts that contributed decisively to her longevity.
“Oppy’s best friend is on its way!”
Spotting dust devils has been relatively rare for Opportunity since landing on Mars on Jan. 24, 2004.
“There are 7 candidates, 6 of which are likely or certain,” Mark Lemmon, rover science team member from Texas A & M University, told Universe Today. “Most were seen in, on the rim of, or adjacent to Endeavour.”
Starting in late January, scientists commanded the golf cart sized Opportunity to drive up the steepest slopes ever attempted by any Mars rover in order to reach rock outcrops where she can conduct breakthrough science investigations on smectite (phyllosilicate) clay mineral bearing rocks yielding clues to Mars watery past.
“We are beginning an imaging and contact science campaign in an area where CRISM spectra show evidence for deep absorptions associated with Fe [Iron], Mg [Magnesium] smectites,” Arvidson explained.
This is especially exciting to researchers because the phyllosilicate clay mineral rocks formed under water wet, non-acidic conditions that are more conducive to the formation of Martian life forms – billions of years ago when the planet was far warmer and wetter.
“We have been in the smectite [phyllosilicate clay mineral] zone for months, ever since we entered Marathon Valley.”
The smectites were discovered via extensive, specially targeted Mars orbital measurements gathered by the CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) spectrometer on NASA’s Mars Reconnaissance Orbiter (MRO) – accomplished earlier at the direction of Arvidson.
So the ancient, weathered slopes around Marathon Valley became a top priority science destination after they were found to hold a motherlode of ‘smectite’ clay minerals based on the CRISM data.
“Marathon Valley is unlike anything we have ever seen. Looks like a mining zone!”
At this moment, the rover is driving to an alternative rock outcrop located on the southwest area of the Knudsen Ridge hilltops after trying three times to get within reach of the clay minerals by extending her instrument laden robotic arm.
Unfortunately, but not unexpectedly, the rover kept slipping on the steep walled slopes – tilted as much as 32 degrees – while repeatedly attempting close approaches to the intended target. Ultimately she came within 3 inches of the surface science target ‘Pvt. Joseph Whitehouse’ – named after a member of the Corps of Discovery.
In fact despite rotating her wheels enough to push uphill about 66 feet (20 meters) if there had been no slippage, engineers discerned from telemetry that slippage was so great that “the vehicle progressed only about 3.5 inches (9 centimeters). This was the third attempt to reach the target and came up a few inches short,” said NASA.
“The rover team reached a tough decision to skip that target and move on.”
So they backed Opportunity downhill about 27 feet (8.2 meters), then drove about 200 feet (about 60 meters) generally southwestward and uphill, toward the next target area.
NASA officials noted that “the previous record for the steepest slope ever driven by any Mars rover was accomplished while Opportunity was approaching “Burns Cliff” about nine months after the mission’s January 2004 landing on Mars.”
Marathon Valley measures about 300 yards or meters long. It cuts downhill through the west rim of Endeavour crater from west to east – the same direction in which Opportunity is currently driving downhill from a mountain summit area atop the crater rim. See our route map below showing the context of the rovers over dozen year long traverse spanning more than the 26 mile distance of a Marathon runners race.
Endeavour crater spans some 22 kilometers (14 miles) in diameter. Opportunity has been exploring Endeavour since arriving at the humongous crater in 2011.
Why are the dust devils a big deal?
Offering more than just a pretty view, the dust devils actually have been associated with springtime Martian winds that clear away the dust obscuring the robots life giving solar panels.
“Opportunity is largely in winter mode sitting on a hill side getting maximum power. But it is in a better power status than in many past winters,” Jim Green, Director of NASA Planetary Sciences at NASA HQ, told Universe Today exclusively.
“I think I know the reason. As one looks across the vistas of Mars in this mosaic Oppys best friend is on its way.”
“The dust devils have been kind to this rover. Even I have a smile on my face when I see what’s coming.”
As of today, Sol 4332, Apr. 1, 2016, Opportunity has taken over 209,200 images and traversed over 26.53 miles (42.69 kilometers) – more than a marathon.
The power output from solar array energy production has climbed to 576 watt-hours, now just past the depths of southern hemisphere Martian winter.
Meanwhile Opportunity’s younger sister rover Curiosity traverses and drills into the basal layers at the base of Mount Sharp.

An unmanned Russian space freighter hauling fresh fruit and over three tons of food, water, supplies and science experiments blasted off today, Thursday, March 31, from the Baikonur Cosmodrome in Kazakhstan, commencing a two-day orbital trek to the six person crew living aboard the International Space Station (ISS).
The successful nighttime liftoff of the Progress 63 cargo ship atop a three stage Soyuz 2.1a booster took place at 12:23 p.m. EDT (10:23 p.m. local time in Baikonur) from Site 31 at Baikonur as the orbiting outpost was flying about 251 miles (400 km) above northeast Iraq.
NASA astronaut and Expedition 47 crew member Jeff Williams captured several elegant views of the Progress launch from his heavenly perch on the station inside the Cupola.
“Fresh fruit is on the way! Here are some of the best pics taken from @Space_Station during today’s #Progress launch,” Williams said on his social media accounts from space.
“Today’s #Progress launch occurred about 5 minutes before we passed over the launch site in Baikonur.”
“Sunset occurred for us about a minute later and shortly after we caught site of the rocket ahead and below us from the Cupola. We continued to catch up to it until it was directly below. We saw the flash of 3rd stage ignition and the subsequent 3rd stage was spectacular. Here are some of the best shots taken from the International Space Station. (note the one taken just after the moment of engine cutoff!) Spectacular!” Williams elaborated.
The Progress 63 resupply ship, also known by its Russian acronym as Progress MS-02, is due to arrive at the station on April 2 for an automated docking to the aft port of the Russian Zvezda Service Module.
After a picture perfect eight and a half minute climb to its initial orbit, the Progress MS-02 separated from the Soyuz third stage and deployed its pair of solar arrays and navigational antennas as planned.
“This was a flawless ascent to orbit for the Progress 63 cargo craft carrying just over three tons of supplies,” said NASA launch commentator Rob Navius during a live launch webcast on NASA TV. “Everything was right on the money.”
“All stages of the Soyuz booster performed to perfection.”
The planned longer two-day and 34 orbit journey rather than a faster 3 or 4 orbit rendezvous and docking is designed to help engineers test out new computer software and vehicle communications gear on this new version of the Progress.
“The two-day rendezvous for the Progress is deliberately planned to enable Russian flight controllers to test new software and communications equipment for the new vehicle configuration that will be standard for future Progress and piloted Soyuz spacecraft,” according to NASA officials.
Docking to the orbiting laboratory is set for approximately 2 p.m. Saturday, April 2.
NASA TV will provide live docking coverage of the Progress 63 arrival starting at 1:15 p.m. on Saturday.
Today’s Progress launch counts as the second of a constellation of three resupply ships from the US and Russia launching to the station over a three successive weeks.
The Orbital ATK ‘SS Rick Husband’ Cygnus resupply spacecraft that launched last week on Tuesday, March 22, 2016 was at the vanguard of the cargo ship trio – as I reported here from on site at the Kennedy Space Center in Florida.
Cygnus was successfully berthed at the Earth-facing port of the Unity module this past Saturday, March 26 – as I reported here.
Following Progress is the SpaceX Return To Flight (RTF) mission dubbed SpaceX CRS-8.
It is slated to launch on April 8 and arrive at the ISS on April 10 for berthing to the Earth-facing port of the Harmony module – at the end of the station where NASA space shuttles formerly docked. It carries another 3.5 tons of supplies.
So altogether the trio of international cargo ships will supply over 12 tons of station supplies in rapid succession over the next 3 weeks.
This choreography will set up America’s Cygnus and Dragon resupply craft to simultaneously be present and reside attached at adjacent ports on the ISS for the first time in history.
Plans currently call for Cygnus to stay at station for approximately two months until May 20th., when it will be unbolted and unberthed for eventual deorbiting and reentry.
Progress 63 will remain at the station for six months.
