KENNEDY SPACE CENTER, FL – MAVEN, NASA’s next spacecraft launching to the Red Planet in barely three days time on Nov. 18 seeks to unlock one of the greatest Martian mysteries; Where did all the water go ?
From the accumulated evidence so far scientists believe that billions of years ago, Mars was gifted with a thick atmosphere like Earth and liquid water flowed across the surface.
The Red Planet was far bluer, warmer, wetter and hospitable to life four billion years ago – truly a lot more Earth-like.
And then Mars lost its atmosphere starting somewhere around 3.5 to 3.7 Billion years ago. As the atmosphere thinned and the pressure decreased, the water evaporated and Mars evolved into the cold arid world we know today.
But why and exactly when did Mars undergo such a radical climatic transformation?
“Where did the water go and where did the carbon dioxide go from the early atmosphere? What were the mechanisms?” asks Bruce Jakosky, MAVEN’s Principal Investigator from the University of Colorado at Boulder
Although there are lots of theories, NASA’s MAVEN Mars orbiter – which stands for Mars Atmosphere and Volatile Evolution – is the first real attempt to investigating these fundamental questions that hold the key to solving the Martian mysteries perplexing the science community.
“We don’t know the driver of the change,” explains Jakosky.
By studying and understanding specific processes in the upper atmosphere of Mars, MAVEN’s seeks to determine how and why Mars atmosphere and water disappeared billions of years ago and what effect that had on the history of climate change and habitability.
“The major questions about the history of Mars center on the history of its climate and atmosphere and how that’s influenced the surface, geology and the possibility for life,” says Jakosky.
MAVEN is equipped with three instrument suites holding nine science instruments
MAVEN will focus on understanding the history of the atmosphere, how the climate has changed through time, and how that influenced the evolution of the surface and the potential for habitability by microbes on Mars.”
“That’s what driving our exploration of Mars with MAVEN,” said Jakosky
The 5,400 pound MAVEN probe carries nine sensors in three instrument suites.
The Particles and Fields Package, provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments to characterize the solar wind and the ionosphere of Mars. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, built by Goddard, will measure the composition of Mars’ upper atmosphere.
I personally inspected MAVEN inside the clean room at the Kennedy Space Center on Sept. 27 with fellow journalists when the solar arrays were fully unfurled.
The probe spanned 37 feet in length from wingtip to wingtip.
Since then MAVEN has been folded and encapsulated inside the payload fairing, transported to the pad at Launch Complex 41 and hoisted on top of the Atlas V rocket on Cape Canaveral Air Force Station (CCAFS) in Florida.
The $671 Million MAVEN spacecraft has been powered on and awaits liftoff.
MAVEN is the second of two Mars bound probes launching from Earth this November.

See below a gallery of Earth from Juno[/caption]
During a crucial speed boosting slingshot maneuver around Earth on Oct. 9, NASA’s Jupiter-bound Juno probe snapped a dazzling gallery of portraits of our Home Planet over the South American coastline and the Atlantic Ocean. See our mosaics of land, sea and swirling clouds above and below, including several shown in false color.
But an unexpected glitch during the do or die swing-by sent the spacecraft into ‘safe mode’ and delayed the transmission of most of the raw imagery and other science observations while mission controllers worked hastily to analyze the problem and successfully restore Juno to full operation on Oct. 12 – but only temporarily!
Because less than 48 hours later, Juno tripped back into safe mode for a second time. Five days later engineers finally recouped Juno and it’s been smooth sailing ever since, the top scientist told Universe Today.
“Juno is now fully operational and on its way to Jupiter,” Juno principal investigator Scott Bolton told me today. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.
“We are completely out of safe mode!”
With the $1.1 Billion Juno probe completely healthy once again and the nail-biting drama past at last, engineers found the time to send the stored photos and research data back to ground station receivers.
“The science team is busy analyzing data from the Earth flyby,” Bolton informed me.
The amateur image processing team of Ken Kremer and Marco Di Lorenzo has stitched together several portraits from raw images captured as Juno sped over Argentina, South America and the South Atlantic Ocean and within 347 miles (560 kilometers) of the surface. We’ve collected the gallery here for all to enjoy.
Several portraits showing the swirling clouds and land masses of the Earth’s globe have already been kindly featured this week by Alan Boyle at NBC News and at the Daily Mail online.
Raw images from the Junocam camera are collected in strips – like a push broom. So they have to be carefully reconstructed and realigned to match up. But it can’t be perfect because the spacecraft is constantly rotating and its speeding past Earth at over 78,000 mph.
So the perspective of Earth’s surface features seen by Junocam is changing during the imaging.
And that’s what is fascinating – to see the sequential view of Earth’s beautiful surface changing as the spacecraft flew over the coast of South America and the South Atlantic towards Africa – from the dayside to the nightside.
It’s rare to get such views since only a few spacecraft have swung by Earth in this manner – for example Galileo and MESSENGER – on their way to distant destinations.
Coincidentally this week, the Cygnus cargo carrier departed the ISS over South America.
Fortunately, the Juno team knew right from the start that the flyby of Earth did accomplish its primary goal of precisely targeting Juno towards Jupiter – to within 2 kilometers of the aim point, despite going into safe mode.
“We are on our way to Jupiter as planned,” Juno Project manager Rick Nybakken, told me in a phone interview soon after the flyby of Earth. Nybakken is from NASA’s Jet Propulsion Lab in Pasadena, CA.
“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” he said.
It also accelerated the ships velocity by 16,330 mph (26,280 km/h) – thereby enabling Juno to be captured into polar orbit about Jupiter on July 4, 2016.
The safe mode did not impact the spacecraft’s trajectory one smidgeon!
It was likely initiated by an incorrect setting for a fault protection trigger for the spacecraft’s battery when Juno was briefly in an eclipse during the flyby.
Nybakken also said that the probe was “power positive and we have full command ability,” while it was in safe mode.
Safe mode is a designated fault protective state that is preprogrammed into spacecraft software in case something goes amiss. It also aims the craft sunwards thereby enabling the solar arrays to keep the vehicle powered.
The Earth flyby maneuver was necessary because the initial Atlas V rocket launch on Aug. 5, 2011 from Cape Canaveral Air Force Station, FL was not powerful enough to place Juno on a direct trajectory flight to Jupiter.
As of today, Juno is more than was 6.7 million miles (10.8 million kilometers) from Earth and 739 million miles (7.95 astronomical units) from Jupiter. It has traveled 1.01 billion miles (1.63 billion kilometers, or 10.9 AU) since launch.
With Juno now on course for our solar system’s largest planet, there won’t be no any new planetary images taken until it arrives at the Jovian system in 2016. Juno will then capture the first ever images of Jupiter’s north and south poles.
We have never seen Jupiter’s poles imaged from the prior space missions, and it’s not possible from Earth.
During a year long mission at Jupiter, Juno will use its nine science instruments to probe deep inside the planet to reveal its origin and evolution.
“Jupiter is the Rosetta Stone of our solar system,” says Bolton. “It is by far the oldest planet, contains more material than all the other planets, asteroids and comets combined and carries deep inside it the story of not only the solar system but of us. Juno is going there as our emissary — to interpret what Jupiter has to say.”
Based on what we’ve seen so far, Junocam is sure to provide spectacular views of the gas giants poles and cloud tops.
Opportunity starts Martian Mountaineering
NASA’s Opportunity rover captured this southward uphill panoramic mosaic on Oct. 21, 2013 (Sol 3463) after beginning to ascend the northwestern slope of “Solander Point” on the western rim of Endeavour Crater – her 1st mountain climbing adventure. The northward-facing slope will tilt the rover’s solar panels toward the sun in the southern-hemisphere winter sky, providing an important energy advantage for continuing mobile operations through the upcoming winter. Assembled from Sol 3463 navcam raw images by Marco Di Lorenzo and Ken Kremer.

“This is our first real Martian mountaineering with Opportunity,” said the principal investigator for the rover, Steve Squyres of Cornell University, Ithaca, N.Y.
And it happened right in the middle of the utterly chaotic US government shutdown ! – that seriously harmed some US science endeavors. And at a spot destined to become a science bonanza in the months and years ahead – so long as she stays alive to explore ever more new frontiers.
On Oct. 8, mission controllers on Earth directed the nearly decade old robot to start the ascent of Solander Point – the northern tip of the tallest hill she has encountered after nearly 10 Earth years on Mars.
The northward-facing slopes at Solander also afford another major advantage. They will tilt the rover’s solar panels toward the sun in the southern-hemisphere winter sky, providing an important energy boost enabling continued mobile operations through the upcoming frigidly harsh winter- her 6th since landing in 2004.
Opportunity will first explore outcrops on the northwestern slopes of Solander Point in search of the chemical ingredients required to sustain life before gradually climbing further uphill to investigate intriguing deposits distributed amongst its stratographic layers.
The rover will initially focus on outcrops located in the lower 20 feet (6 meters) above the surrounding plains on slopes as steep as 15 to 20 degrees.
At some later time, Opportunity may ascend Solander farther upward, which peaks about 130 feet (40 meters) above the crater plains.
“We expect we will reach some of the oldest rocks we have seen with this rover — a glimpse back into the ancient past of Mars,” says Squyres.
NASA’s powerful Mars Reconnaissance Orbiter (MRO) circling overhead recently succeeded in identifying clay-bearing rocks during new high resolution survey scans of Solander Point!
As I reported previously, the specially collected high resolution observations by the orbiters Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) were collected in August and being analyzed by the science team. They will be used to direct Opportunity to the most productive targets of interest
“CRISM data were collected,” Ray Arvidson told Universe Today. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.
“They show really interesting spectral features in the [Solander Point] rim materials.”
The new CRISM survey from Mars orbit yielded mineral maps which vastly improves the spectral resolution – from 18 meters per pixel down to 5 meters per pixel.
This past spring and summer, Opportunity drove several months from the Cape York rim segment to Solander Point.
“At Cape York, we found fantastic things,” Squyres said. “Gypsum veins, clay-rich terrain, the spherules we call newberries. We know there are even larger exposures of clay-rich materials where we’re headed. They might look like what we found at Cape York or they might be completely different.”
Clay minerals, or phyllosilicates, form in neutral water that is more conducive to life.
At the base of Solander, the six wheeled rover discovered a transition zone between a sulfate-rich geological formation and an older formation. Sulfate-rich rocks form in a wet environment that was very acidic and less favorable to life.
Solander Point is located at the western rim of the vast expanse of Endeavour crater – some 22 kilometers (14 miles) in diameter.
Today marks Opportunity’s 3466th Sol or Martian Day roving Mars – for what was expected to be only a 90 Sol mission.
So far she has snapped over 185,200 amazing images on the first overland expedition across the Red Planet.
Her total odometry stands at over 23.89 miles (38.45 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.
On the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp and recently discovered a patch of pebbles formed by flowing liquid water.
Juno swoops over Argentina

Engineers have deftly managed to successfully restore NASA’s Jupiter-bound Juno probe back to full operation following an unexpected glitch that placed the ship into ‘safe mode’ during the speed boosting swing-by of Earth on Wednesday, Oct. 9 – the mission’s top scientist told Universe Today late Friday.
“Juno came out of safe mode today!” Juno principal investigator Scott Bolton happily told me Friday evening. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.
The solar powered Juno spacecraft conducted a crucial slingshot maneuver by Earth on Wednesday that accelerated its velocity by 16,330 mph (26,280 km/h) thereby enabling it to be captured into polar orbit about Jupiter on July 4, 2016.
“The safe mode did not impact the spacecraft’s trajectory one smidgeon!”
Juno exited safe mode at 5:12 p.m. ET Friday, according to a statement from the Southwest Research Institute. Safe mode is a designated fault protective state that is preprogrammed into spacecraft software in case something goes amiss.
“The spacecraft is currently operating nominally and all systems are fully functional,” said the SwRI statement.
Although the Earth flyby did accomplish its primary goal of precisely targeting Juno towards Jupiter – within 2 kilometers of the aim point ! – the ship also suffered an unexplained anomaly that placed Juno into ‘safe mode’ at some point during the swoop past Earth.
“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Juno Project manager Rick Nybakken, told me in a phone interview soon after Wednesday’s flyby of Earth. Nybakken is from NASA’s Jet Propulsion Lab in Pasadena, CA.
Nybakken also said that the probe was “power positive and we have full command ability.”
So the mission operations teams at JPL and prime contractor Lockheed Martin were optimistic about resolving the safe mode issue right from the outset.
“The spacecraft acted as expected during the transition into and while in safe mode,” acording to SwRI.
During the flyby, the science team also planned to observe Earth using most of Juno’s nine science instruments since the slingshot also serves as an important dress rehearsal and key test of the spacecraft’s instruments, systems and flight operations teams.
“The Juno science team is continuing to analyze data acquired by the spacecraft’s science instruments during the flyby. Most data and images were downlinked prior to the safe mode event.”
Juno’s closest approach took place over the ocean just off the tip of South Africa at about 561 kilometers (349 miles).
Juno launched atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.
The $1.1 Billion Juno probe is continuing on its 2.8 Billion kilometer (1.7 Billion mile) outbound trek to the Jovian system.
During a one year long science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution.
“Jupiter is the Rosetta Stone of our solar system,” says Bolton. “It is by far the oldest planet, contains more material than all the other planets, asteroids and comets combined and carries deep inside it the story of not only the solar system but of us. Juno is going there as our emissary — to interpret what Jupiter has to say.”

Following the speed boosting slingshot of Earth on Wednesday, Oct. 9, that sent NASA’s Juno orbiter hurtling towards Jupiter, the probe has successfully transmitted back data and the very first flyby images despite unexpectedly going into ‘safe mode’ during the critical maneuver.
“Juno is transmitting telemetry today,” spokesman Guy Webster, of NASA’s Jet Propulsion Lab (JPL), told me in a phone interview late today (Oct. 10), as Juno continues sailing on its 2.8 Billion kilometer (1.7 Billion mile) outbound trek to the Jovian system.
The new images of Earth captured by the Junocam imager serves as tangible proof that Juno is communicating.
“Juno is still in safe mode today (Oct. 10),” Webster told Universe Today.
“Teams at mission control at JPL and Lockheed Martin are actively working to bring Juno out of safe mode. And that could still require a few days,” Webster explained.
Lockheed Martin is the prime contractor for Juno.
The initial raw images of Earth snapped by the craft’s Junocam imager were received by ground stations late today.
See above a day light image mosaic which I reconstructed and realigned based on the original raw image (see below) taken with the camera’s methane filter on Oct. 9 at 12:06:30 PDT (3:06:30 PM EST). Juno was to be flying over South America and the southern Atlantic Ocean.
Juno performed a crucial swingby of Earth on Wednesday that accelerated the probe by 16330 MPH to enable it to arrive in orbit around Jupiter on July 4, 2016.
However the gravity assist maneuver did not go entirely as planned.
Shortly after Wednesday’s flyby, Juno Project manager Rick Nybakken, of JPL, told me in a phone interview that Juno had entered safe mode but that the probe was “power positive and we have full command ability.”
“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken explained.
The safe mode was triggered while Juno was in an eclipse mode, the only eclipse it will experience during its entire mission.
The Earth flyby did accomplish its objective by placing the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.
“We are on our way to Jupiter as planned!”
“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” Nybakken stated.
Juno’s closest approach was over South Africa at about 561 kilometers (349 miles).
During the flyby, the science team also planned to observe Earth using most of Juno’s nine science instruments since the slingshot also serves as a key test of the spacecraft systems and the flight operations teams.
Juno also was to capture an unprecedented new movie of the Earth/Moon system.
Many more images were snapped and should be transmitted in coming days that eventually will show a beautiful view of the Earth and Moon from space.
“During the earth flyby we have most of our instruments on and will obtain a unique movie of the Earth Moon system on our approach, Juno principal investigator Scott Bolton told me. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.
“We will also calibrate instuments and measure earth’s magnetosphere, obtain closeup images of the Earth and the Moon in UV [ultraviolet] and IR [infrared],” Bolton explained to Universe Today.
Juno is approaching the Earth from deep space, from the sunlit side.
“Juno will take never-before-seen images of the Earth-moon system, giving us a chance to see what we look like from Mars or Jupiter’” says Bolton.
Here is a description of Junocam from the developer – Malin Space Science Systems
“Like previous MSSS cameras (e.g., Mars Reconnaissance Orbiter’s Mars Color Imager) Junocam is a “pushframe” imager. The detector has multiple filter strips, each with a different bandpass, bonded directly to its photoactive surface. Each strip extends the entire width of the detector, but only a fraction of its height; Junocam’s filter strips are 1600 pixels wide and about 155 rows high. The filter strips are scanned across the target by spacecraft rotation. At the nominal spin rate of 2 RPM, frames are acquired about every 400 milliseconds. Junocam has four filters: three visible (red/green/blue) and a narrowband “methane” filter centered at about 890 nm.”
Juno launched atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.
During a one year long science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s origin and evolution.
Developing story – NASA’s Juno-bound Jupiter orbiter successfully blazed past Earth this afternoon (Oct. 9) and gained its huge and critical gravity assisted speed boost that’s absolutely essential to reach the Jovian system in 2016.
However, Juno’s project manager Rick Nybakken told me moments ago that the Juno spacecraft unexpectedly entered ‘safe mode’ during the fly by maneuver and the mission teams are assessing the situation.
But the very good news is “Juno is power positive at this time. And we have full command ability,” said Nybakken in an exclusive phone interview with me.
“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken told me. Nybakken is the Juno mission project manager at NASA’s Jet Propulsion Lab in Pasadena, CA.
Furthermore, the Earth flyby did place the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.
“We are on our way to Jupiter as planned!”
“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is.”
Juno’s closest approach was over South Africa at about 500 kilometers (350 miles).
“Juno hit the target corridor within 2 km of the aim point,” Nybakken elaborated to Universe Today.
Juno needs the 16,330 mph velocity boost from the Earth swingby because the Atlas V launcher was not powerful enough to hurtle the 8000 pound (3267 kg) craft fast enough on a direct path to Jupiter.
And the team is in full radio contact with the probe. Safe mode is a designated protective state.
“Prior to the eclipse, which was a few minutes earlier than closest approach, the spacecraft was ‘nominal’. When we came out of the eclipse Juno was in safe mode,” Nybakken stated.
“We are going through safe mode diagnostics steps right now.”
“We have established full uplink and downlink. And we have full command ability of the spacecraft.”
Speed boosting slingshots have been used on numerous planetary missions in the past
The spacecraft’s power situation and health is as good as can be expected.
“Juno is power positive at this time and sun pointed and stable. So we are very pleased about that,” Nybakken explained.
I asked if Juno had ever entered ‘safe mode’ before?
“We have never been in safe mode before. We are in a safe, stable state.”
“We are investigating this,” said Nybakken.
Today’s (Oct. 9) Earth flyby is the only time the spacecraft experiences an eclipse period during Juno’s entire five year and 1.7 Billion mile (2.8 Billion km) trek to Jupiter, the largest planet in our solar system.
When it finally arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant.
NASA’s Juno spacecraft blasted off atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.
The science team had also hoped to use the on board JunoCam imager to make a cool and unprecedented movie of Earth as it approached from the sunlit side – showing the passage as though you were a visitor from outer space.
I had an inkling that something might be amiss this afternoon when no images of Earth appeared on the Juno mission website.
So I asked the status.
“We don’t know yet if any images of Earth were collected. We hope to know soon.”
Juno flew past the Moon before the gravity assist slingshot with Earth. And it did manage to successfully capture several lunar images. See the images herein.

Note: Due to the continuing chaos resulting from the US government partial shutdown caused by gridlocked politico’s in Washington DC, NASA public affairs remains shut down and is issuing no official announcements on virtually anything related to NASA! This pertains to Juno’s flyby, LADEE’s lunar arrival on Oct. 6, MAVEN’s upcoming launch in November, Cygnus at the ISS, and more!
Stay tuned here for continuing Juno, LADEE, MAVEN and more up-to-date NASA news.

NASA’s solar powered Jupiter-bound Juno orbiter is careening towards Earth for an absolutely critical gravity assisted fly by speed boost while capturing an unprecedented movie view of the Earth/Moon system – on its ultimate quest to unveiling Jupiter’s genesis!
“Juno will flyby Earth on October 9 to get a gravity boost and increase its speed in orbit around the Sun so that it can reach Jupiter on July 4, 2016,” Juno chief scientist Dr. Scott Bolton told Universe Today in an exclusive new Juno mission update – as the clock is ticking to zero hour. “The closest approach is over South Africa.”
All this ‘high frontier’ action comes amidst the utterly chaotic US government partial shutdown, that threatened the launch of the MAVEN Mars orbiter, has halted activity on many other NASA projects and stopped public announcements of the safe arrival of NASA’s LADEE lunar orbiter on Oct. 6, Juno’s flyby and virtually everything else related to NASA!
Bolton confirmed that the shutdown fortunately hasn’t altered or killed Juno’s flyby objectives. And ops teams at prime contractor Lockheed Martin have rehearsed and all set.
And some more good news is that Slooh will track the Juno Earth Flyby “LIVE” – for those hoping to follow along. Complete details below!
“The shutdown hasn’t affected our operations or plans, Bolton told me. Bolton is Juno’s principal investigator from the Southwest Research Institute (SwRI), San Antonio, Texas.
“Juno is 100% healthy.”
“But NASA is unable to participate in our public affairs and press activities,” Bolton elaborated.
97% of NASA’s employees are furloughed – including public affairs – due to the legal requirements of the shutdown!
Juno will also capture an unprecedented new movie of the Earth/Moon system.
A full up science investigation of our Home Planet by Juno is planned, that will also serve as a key test of the spacecraft and its bevy of state of the art instruments.
“During the earth flyby we have most of our instruments on and will obtain a unique movie of the Earth Moon system on our approach.
“We will also calibrate instuments and measure earth’s magnetosphere, obtain closeup images of the Earth and the Moon in UV [ultraviolet] and IR [infrared],” Bolton explained to Universe Today.
The flyby will accelerate the spacecraft’s velocity by 16,330 mph.
Where is the best view of Juno’s flyby, I asked?
“The closest approach is over South Africa and is about 500 kilometers [350 miles],” Bolton replied.
The time of closest approach is 3:21 p.m. EDT (12:21 PDT / 19:21 UTC) on Oct. 9, 2013
Watch this mission produced video about Juno and the Earth flyby:
Video caption: On Oct. 9, 2013, NASA’s Jupiter-bound Juno spacecraft is making a quick pass to get a gravity boost from the mother planet. Dr. Scott Bolton of Southwest Research Institute® is the Juno mission principal investigator, leading an international science team seeking to answer some fundamental questions about the gas giant and, in turn, about the processes that led to formation of our solar system.
NASA’s Juno spacecraft blasted off atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 to begin a 2.8 billion kilometer science trek to discover the genesis of Jupiter hidden deep inside the planet’s interior.
Juno is on a 5 year and 1.7 Billion mile (2.8 Billion km) trek to the largest planet in our solar system. When it arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant.
During a one year science mission – entailing 33 orbits lasting 11 days each – the probe will plunge to within about 3000 miles of the turbulent cloud tops and collect unprecedented new data that will unveil the hidden inner secrets of Jupiter’s genesis and evolution.
The goal is to find out more about the planets origins, interior structure and atmosphere, observe the aurora, map the intense magnetic field and investigate the existence of a solid planetary core
Why does Juno need a speed boost from Earth?
“A direct mission to Jupiter would have required about 50 percent more fuel than we loaded,” said Tim Gasparrini, Juno program manager for Lockheed Martin Space Systems, in a statement.
“Had we not chosen to do the flyby, the mission would have required a bigger launch vehicle, a larger spacecraft and would have been more expensive.”
Viewers near Cape Town, South Africa will have the best opportunity to view the spacecraft traveling across the sky.
Juno itself will most likely not be visible to the unaided eye, but binoculars or a small telescope with a wide field should provide an opportunity to view, according to a Slooh statement.
Slooh will track Juno live on October 9th, 2013.
Check here for international starting times: http://goo.gl/7ducFs – and for the Slooh broadcast hosted by Paul Cox.
Viewers can view the event live on Slooh.com using their computer or mobile device, or by downloading the free Slooh iPad app in the iTunes store. Questions can be asked during the broadcast via Twitter by using the hashtag #nasajuno -says Slooh.
Amidst the government shutdown, Juno prime contractor Lockheed Martin is working diligently to ensure the mission success.
Because there are NO 2nd chances!
“The team is 100 percent focused on executing the Earth flyby successfully,” said Gasparrini.
“We’ve spent a lot of time looking at possible off-nominal conditions. In the presence of a fault, the spacecraft will stay healthy and will perform as planned.”
Stay tuned here for continuing Juno, LADEE, MAVEN and more up-to-date NASA news.

What’s not at all clear is whether Juno will detect any signs of ‘intelligent life’ in Washington D.C.!

NASA’s intrepid Opportunity rover has begun an exciting new phase in her epic journey – the ascent of Solander Point, the first mountain she will ever climb, after roving the Red Planet for nearly a decade. See the rovers tilted look-back view in our Sol 3431 mosaic above.
Furthermore, ground breaking discoveries providing new clues in search of the chemical ingredients required to sustain life are sure to follow as the rover investigates intriguing stratographic deposits distributed amongst Solander’s hills layers.
Why ? Because NASA’s powerful Mars Reconnaissance Orbiter (MRO) circling overhead has also recently succeeded in collecting “really interesting” new high resolution survey scans of Solander Point! Read my prior pre-survey account – here.
So says Ray Arvidson, the mission’s deputy principal scientific investigator, in an exclusive Opportunity news update to Universe Today. The new MRO data are crucial for targeting the rover’s driving in coming months.
After gaining approval from NASA, engineers successfully aimed the CRISM mineral mapping spectrometer aboard MRO at Solander Point and captured reams of new high resolution measurements that will inform the scientists about the mineralogical make up of Solander.
“CRISM data were collected,” Arvidson told Universe Today.
“They show really interesting spectral features in the [Endeavour Crater] rim materials.”
Solander Point is an eroded ridge located along the western rim of huge Endeavour Crater where Opportunity is currently located.
“Opportunity is on the bench at the tip of Solander Point,” Ray Arvidson told Universe Today exclusively. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.
At the bench, the long lived rover has begun scaling Solander in search of science and life giving sun.
“The CRISM data are being discussed by the MER [Mars Exploration Rover] Team this week,” Arvidson told me.
And it will take some time to review and interpret the bountiful new spectral data and decide on a course of action.
“For the CRISM data analysis we will have the MER Team see the results and agree.”
Expect that analysis to take a “couple of weeks” said Arvidson.
The new CRISM survey from Mars orbit will vastly improve the spectral resolution – from 18 meters per pixel down to 5 meters per pixel.
Another important point about ‘Solander Point’ is that it also offers northerly tilted slopes that will maximize the power generation during Opportunity’s upcoming 6th Martian winter.
In order to survive those Antarctic like, ‘bone chilling” winter temperatures on the Red Planet and continue with her epic mission, the engineers must drive the rover so that the solar wings are pointed favorably towards the sun.
And don’t forget that winter’s last six full months – that’s twice as long on Mars as compared to Earth.
The daily solar power output has been declining as Mars southern hemisphere enters late fall.
After traversing several months across the crater floor from the Cape York rim segment to Solander, Opportunity arrived at the foothills of Solander Point.
Solander and Cape York are part of a long chain of eroded segments of the crater wall of Endeavour crater which spans a humongous 14 miles (22 kilometers) wide.
Solander Point may harbor deposits of phyllosilicate clay minerals – which form in neutral pH water – in a thick layer of rock stacks indicative of a past Martian habitable zone.
The science team is looking at the new CRISM measurements, hunting for signatures of phyllosilicate clay minerals and other minerals and features of interest.
“Opportunity is on the bench on the northwest side of the tip of Solander Point,” Arvidson explained.
Since pulling up to Solander, the robot has spent over a month investigating the bench surrounding the mountain to put it the entire alien Martian terrain in context for a better understanding of Mars geologic history over billions of years.
Eons ago, Mars was far warmer and wetter and more hospitable to life.
“The rover is finishing up work on defining the stratigraphy, structure, and composition of the bench materials.”
“We are working our way counterclockwise on the bench to reach the steep slopes associated with the Noachian outcrops that are part of the Endeavour rim,” Arvidson elaborated.
“Opportunity is slightly tipped to the north to catch the sun.”
“Probably this week we will direct the rover to head south along the western boundary between the bench and the rim materials, keeping on northerly tilts,” Arvidson told me.
How does the bench at Solander compare to other areas investigated at Endeavour crater, I asked.
“The Solander Bench looks like the bench we saw around Cape York and around Sutherland Point and Nobbys Head,” replied Arvidson.
The rover recently investigated an outcrop target called ‘Poverty Bush’. She deployed her 3 foot long (1 meter) robotic arm and collected photos with the Microscopic Imager (MI) and collected several days of spectral measurements with the Alpha Particle X-ray Spectrometer (APXS).
Thereafter she resumed driving to the west/northwest around Solander.
“On September 13, Opportunity finally landed on the bed rock of Solander Point,” wrote Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science, in his latest field report about the MER mission.
“The terrain right here is awesome,” according to Crumpler.
“There are several geologic units that are overlapping here. And Opportunity is sitting on the contact.”
“On the east side of the contact are rocks maybe a billion years older than those on the west side of the contact. This sort of age progression is what geologists look for when trying to understand the past by reading the rocks.”
“Opportunity is allowing us for the first time to do not only fundamental geographic exploration, but it is enabling on the ground geologic study of past climatic history on Mars,” notes Crumpler.
Today marks Opportunity’s 3441st Sol or Martian Day roving Mars – for what was expected to be only a 90 Sol mission.
So far she has snapped over 184,500 amazing images on the first overland expedition across the Red Planet.
Her total odometry stands at over 23.82 miles (38.34 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.
Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp and just discovered water altered pebbles at the intriguing ‘Darwin’ outcrop.
And NASA is in the final stages of processing of MAVEN, the agencies next orbiter, scheduled to blast off from Cape Canaveral on Nov.18 – see my upcoming up close article.

NASA’s Curiosity rover has discovered a new patch of pebbles formed and rounded eons ago by flowing liquid water on the Red Planet’s surface along the route she is trekking across to reach the base of Mount Sharp – the primary destination of her landmark mission.
Curiosity made the new finding at a sandstone outcrop called ‘Darwin’ during a brief science stopover spot called ‘Waypoint 1’.
Before arriving at Waypoint 1, the question was- “Did life giving water once flow here on the Red Planet?
The answer now is clearly ‘Yes!’ – And it demonstrates the teams wisdom in pausing to inspect ‘Darwin’.
The discovery at Darwin is significant because it significantly broadens the area here that was altered by flowing liquid water.
The presence of water is an essential prerequisite for the formation and evolution of life.
“Curiosity has arrived at Waypoint 1,” project scientist John Grotzinger, of the California Institute of Technology in Pasadena, told Universe Today at the time.
The robot pulled into ‘Waypoint 1’ on Sept. 12 (Sol 392).
“It’s a chance to study outcrops along the way,” Grotzinger told me.
The six wheeled rover is in the initial stages of what is sure to be an epic trek across the floor of her landing site inside the nearly 100 mile wide Gale Crater – that is dominated by humongous Mount Sharp that reaches over 3 miles (5 Kilometers) into the red Martian Sky.
“We examined pebbly sandstone deposited by water flowing over the surface, and veins or fractures in the rock,” said Dawn Sumner of University of California, Davis, a Curiosity science team member with a leadership role in planning the stop, in a NASA statement about Darwin and Waypoint 1.
“We know the veins are younger than the sandstone because they cut through it, but they appear to be filled with grains like the sandstone.”
Waypoint 1 is the first of up to five waypoint stops planned along the roving route that stretches about 5.3 miles (8.6 kilometers) between the “Glenelg” area, where Curiosity worked for more than six months through the first half of 2013, and the currently planned entry point at the base of Mount Sharp.
To date, the robot has now driven nearly 20% of the way towards the base of the giant layered Martian mountain she will eventually scale in search of life’s ingredients.
“Darwin is named after a geologic formation of rocks from Antarctica,” Grotzinger informed Universe Today.
‘Waypoint 1’ was an area of intriguing outcrops that was chosen based on high resolution orbital imagery taken by NASA’s Mars Reconnaissance Orbiter (MRO) circling some 200 miles overhead.
Investigation of the conglomerate rock outcrop dubbed ‘Darwin’ was the top priority of the Waypoint 1 stop.
The finding of a cache of watery mineral veins was a big added science bonus that actually indicates a more complicated story in Mars past – to the delight of the science team.
“We want to understand the history of water in Gale Crater,” Sumner said.
“Did the water flow that deposited the pebbly sandstone at Waypoint 1 occur at about the same time as the water flow at Yellowknife Bay? If the same fluid flow produced the veins here and the veins at Yellowknife Bay, you would expect the veins to have the same composition.’
“We see that the veins are different, so we know the history is complicated. We use these observations to piece together the long-term history.”
The Rover inspected Darwin from two different positions over 4 days, or Martian Sols and conducted ‘contact science’ by deploying the robotic arm and engaging the science instrument camera and spectrometer mounted on the turret at the arms terminus.
The Alpha Particle X-ray Spectrometer (APXS) collected spectral measurements of the elemental chemistry and the Mars Hand Lens Imager is a camera showing the outcrops textures, shapes and colors.
What’s the origin of Darwin’s name?
“Darwin comes from a list of 100 names the team put together to designate rocks in the Mawson Quadrangle – Mawson is the name of a geologist who studied Antarctic geology,” Grotzinger told me.
“We’ll stay just a couple of sols at Waypoint 1 and then we hit the road again,” Grotzinger told me.
And indeed on Sept. 22, the rover departed Darwin and Waypoint 1 on a westward heading to resume the many months long journey to Mount Sharp.

NASA’s Curiosity Mars rover has just rolled into an intriguing site called ‘Darwin’ at ‘Waypoint 1’- having quickly picked up the driving pace since embarking at last on her epic trek to mysterious Mount Sharp more than two months ago. Did life giving water once flow here on the Red Planet?
Because the long journey to Mount Sharp – the robots primary destination – was certain to last nearly a year, the science team carefully choose a few stopping points for study along the way to help characterize the local terrain. And Curiosity has just pulled into the first of these so called ‘Waypoints’ on Sept 12 (Sol 392), the lead scientist confirmed to Universe Today.
“Curiosity has arrived at Waypoint 1,” project scientist John Grotzinger, of the California Institute of Technology in Pasadena, told Universe Today.
“Darwin is named after a geologic formation of rocks from Antarctica.”
She has now driven nearly 20% of the way towards the base of the giant layered Martian mountain she will eventually scale in search of life’s ingredients.
Altogether, the team selected five ‘Waypoints’ to investigate for a few days each as Curiosity travels in a southwestward direction on the road from the first major science destination in the ‘Glenelg’ area to the foothills of Mount Sharp, says Grotzinger.
“We’ll stay just a couple of sols at Waypoint 1 and then we hit the road again,” Grotzinger told me.
‘Waypoint 1’ is an area of intriguing outcrops that was chosen based on high resolution orbital imagery taken by NASA’s Mars Reconnaissance Orbiter (MRO) circling some 200 miles overhead. See route map herein.
In fact the team is rather excited about ‘Waypoint 1’ that’s dominated by the tantalizing rocky outcrop discovered there nicknamed ‘Darwin’.
Although Curiosity will only stay a short time at each of the stops, the measurements collected at each ‘Waypoint’ will provide essential clues to the overall geologic and environmental history of the six wheeled rover’s touchdown zone.
“Waypoint 1 was chosen to help break up the drive,” Grotzinger explained to Universe Today.
“It’s a chance to study outcrops along the way.”
The images from MRO are invaluable in aiding the rover handlers planning activities, selecting Curiosity’s driving route and targeting of the most fruitful science forays during the long trek to Mount Sharp – besides being absolutely crucial for the selection of Gale Crater as the robots landing site in August 2012.
The ‘Darwin’ outcrop may provide more data on the flow of liquid water across the crater floor.
The scientists goal is to compare the floor of Gale Crater to the sedimentary layers of 3 mile high (5 kilometer high) Mount Sharp.
Waypoint 1 is just over 1 mile along the approximately 5.3-mile (8.6-kilometer) route from ‘Glenelg’ to the entry point at the base of Mount Sharp.
Curiosity spent over six months investigating the ‘Yellowknife Bay’ area inside Glenelg before departing on July 4, 2013.
What’s the origin of Darwin’s name?
“Darwin comes from a list of 100 names the team put together to designate rocks in the Mawson Quadrangle – Mawson is the name of a geologist who studied Antarctic geology,” Grotzinger told me.
“Recently we left the Yellowknife Quadrangle, so instead of naming rocks after geological formations in Canada’s north, we now turn to formation names of rocks from Antarctica, and Darwin is one of them.
“That will be the theme until we cross into the next quad,” Grotzinger explained.
Inside Yellowknife Bay, Curiosity conducted the historic first interplanetary drilling into Red Planet rocks and subsequent sample analysis with her duo of state of the art chemistry labs – SAM and CheMin.
At Yellowknife Bay, the 1 ton robot discovered a habitable environment containing the chemical ingredients that could sustain Martian microbes- thereby already accomplishing the primary goal of NASA’s flagship mission to Mars.
“We want to know how the rocks at Yellowknife Bay are related to what we’ll see at Mount Sharp,” Grotzinger elaborated in a NASA statement. “That’s what we intend to get from the waypoints between them. We’ll use them to stitch together a timeline — which layers are older, which are younger.”
On Sept. 5, Curiosity set a new one-day distance driving record for the longest drive yet by advancing 464 feet (141.5 meters) on her 13th month on the Red Planet.
As Curiosity neared Waypoint 1 she stopped at a rise called ‘Panorama Point’ on Sept. 7, spotted an outcrop of light toned streaks informally dubbed ‘Darwin and used her MastCam telephoto camera to collect high resolution imagery.
Curiosity will use her cameras, spectrometers and robotic arm for contact science and a “full bore science campaign” involving in-depth mineral and chemical composition analysis of Darwin and Waypoint 1 for the next few Sols, or Martian days, before resuming the trek to Mount Sharp that dominates the center of Gale Crater.
She will not conduct any drilling here or at the other waypoints, several team members have told me, unless there is some truly remarkable ‘Mars-shattering’ discovery.
Why is Curiosity now able to drive longer than ever before?
“We have put some new software – called autonav, or autonomous navigation – on the vehicle right after the conjunction period back in March 2013,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today.
“This will increase our ability to drive. But how much it helps really depends on the terrain.”
And so far the terrain has cooperated.
“We are on a general heading of southwest to Mount Sharp,” said Erickson. See the NASA JPL route map.
“We have been going through various options of different planned routes.”
As of today (Sol 394), Curiosity remains healthy, has traveled 2.9 kilometers and snapped over 82,000 images.
If all goes well Curiosity could reach the entry point to Mount Sharp sometime during Spring 2014, at her current driving pace.
