18 months into her mission to discover a habitable zone on the Red Planet, NASA’s Curiosity rover has at last looked back to the inhabited zone of all humanity and snapped her 1st image of all 7 Billion Earthlings living on the Home Planet.
“Look Back in Wonder… My first picture of Earth from the surface of Mars,” tweeted Curiosity today.
You are there! See yourselves in the spectacular imagery from the Red Planet’s surface at the ‘Dingo Gap’ inside Gale Crater – above and below.
Car sized Curiosity captured the evocative image of Earth as an evening star in the Martian sky just days ago on Jan. 31, 2014, or Sol 529, some 80 minutes after sunset.
And what’s more is that the evening sky view even includes the Earth’s Moon!

Earth shines brilliantly as the brightest beacon in the Martian twilight sky view taken from the 1 ton rovers current location at the edge of a sand dune dubbed the ‘Dingo Gap.’
“A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright “evening stars,” said NASA in a statement issued today.

Processing has removed the numerous cosmic ray strikes – see raw image below.
Right now Curiosity’s handlers are pondering whether to climb over the 1 meter tall sand dune and cross into the smooth terrain of the valley beyond the ‘Dingo Gap’ – as an alternate path to minimize damaging encounters with sharp edged Martian rocks that are puncturing holes and ripping tears into the robots six wheels.
To be clear, these are not the first images of the Earth from Mars orbit or Mars surface.
Two of NASA’s other Red Planet explorers also imaged Earth; Mars Global Surveyor in 2003 and Mars Reconnaissance Orbiter in 2007.
More recently, NASA’s Cassini orbiter at Saturn spied the Earth and Moon during the Wave at Saturn event in July 2013 from a distance of 898 million miles (1.44 billion kilometers).
And still more images of the Earth from NASA’s Mariner 10 and Juno Jupiter orbiter in my recent planetary exploration story – here
The most famous and distant of all is the ‘Pale Blue Dot’ image of Earth taken by NASA’s Voyager 1 probe in 1990 from about 6 billion kilometers (3.7 billion miles) away.

Ariane 5 launch on Feb. 6, 2013 captured on camera by NASA astronaut Rick Mastracchio
We all know what a big rocket launch looks like from the ground, but this is what it looks like from above the ground — 260 miles above the ground! The photo above was captured from the Space Station earlier today by NASA astronaut Rick Mastracchio, and it shows the contrail from a heavy-lift Ariane 5 that had just launched from ESA’s spaceport on the French Guiana coast: flight VA217, Arianespace’s milestone 250th launch carrying the ABS-2 and Athena-Fidus satellites into orbit.
Rick shared his view on Twitter with his nearly 39,000 followers, and now less than an hour later, we’re sharing it here. (Isn’t technology wonderful?)
For a more “natural” look, here it is reversed:
Rick Mastracchio’s photo of the Ariane 5 launch, rotated 180 degrees.
The ISS was in the process of passing over Costa Rica when the image was taken. The rocket launched from Kourou, French Guiana — about 2,175 miles (3,500 km) away. What a view!
For this and more great images from orbit follow Rick on Twitter @AstroRM.
Watch a video of the VA217 launch below:
The 250th launch performed by Arianespace lifted off from ESA’s spaceport in French Guiana, delivering a dual-satellite payload into geostationary transfer orbit: ABS-2 for global satellite operator ABS, and Athena-Fidus for the defense/homeland security needs of France and Italy. The flight lasted just over 32 minutes. (Source)

Ever since the first relay for the 1936 summer Olympic games in Berlin, Olympic torches have traditionally been used to carry a burning flame — symbolically and physically — from Greece to the host country’s stadium. These journeys, undertaken by privileged individuals and athletes from around the world, span months and many thousands of miles… but this year, the fire illuminating the 2014 Winter Olympics in Sochi, Russia will be ignited with a torch that has truly traveled around the globe — many times, in fact.
On Nov. 6, 2013 (Nov. 7 UT) a Soyuz TMA-11M rocket launched from Baikonur Cosmodrome in Kazakhstan ferrying the Expedition 38/39 crew to the ISS. Along with their mission supplies and personal items, the crew members brought along something special: a torch for the 2014 Olympics.
The torch was brought into space two days later by Expedition 38 crew members Oleg Kotov and Sergei Ryazanskiy during an EVA on Nov. 9, and handed off from one cosmonaut to the other in a symbolic relay in orbit, the first to be carried out 265 miles above the planet traveling 17,500 mph. (Watch a video of the EVA below.)
The Olympic torch in orbit during an EVA on Nov. 9, 2013
I say “symbolic” because the torch was not lit during its time aboard the ISS or, obviously, while in space. (Open flames are highly frowned upon aboard Station!) Still, it was the first time in history an Olympic torch, a symbol of peace, human achievement, and international cooperation, has been brought aboard the Space Station — which itself represents the same noble values.
Considering the ISS travels around the Earth 16 times each day, and the torch spent nearly four days in space, that’s one well-traveled fire bearer!
The spacefaring torch was carried back to Earth with Expedition 37 crew members Karen Nyberg of NASA, Fyodor Yurchikhin of the Russian Federal Space Agency, and Luca Parmitano of the European Space Agency on Sunday, Nov. 10. And while the actual Olympic flame had continued to be carried by torchbearers across more than 40,000 miles through 2,900 towns and villages in Russia, it will be that particular spacefaring torch that will be used to light the 2014 Olympic cauldron during the Opening Ceremony in Sochi on Feb. 7.
“As the torch is used to light the Olympic flame in Sochi, and symbolizes harmony and goodwill throughout the games, the space station will remain one of the brightest objects in the night sky, a beacon of international cooperation and research providing tangible benefits for all humanity.” (NASA)

It won’t be long before we start to get the technical details of Inspiration Mars’ daring proposition to send a married couple on a round-trip journey to the Red Planet. The private organization, along with the Mars Society, announced that 38 teams have expressed an intention to participate in a design competition that will see public presentations this spring.
A full list of the university groups is available here, with 56 post-secondary institutions represented from 15 countries (the United States, Canada, Russia, the Netherlands, Germany, Austria, Italy, the United Kingdom, Portugal, Poland, Mauritius, India, Bangladesh, Japan and Colombia.)
“We want to engage the explorers of tomorrow with a real and exciting mission, and demonstrate what a powerful force space exploration can be in inspiring young people to develop their talent. This contest will accomplish both of those objectives,” stated Dennis Tito, who is Inspiration Mars executive director.
Now that the teams are announced, their next job is to submit the actual proposals. Design reports are due March 15. Once the top 10 are selected, those teams will go to the NASA Ames Research Center to make public presentations and compete in April 2014. Six judges will be drawn equally from the Mars Society, Inspiration Mars and NASA.

Exactly 40 Years ago today on Feb. 5, 1974, Mariner 10, accomplished a history making and groundbreaking feat when the NASA science probe became the first spacecraft ever to test out and execute the technique known as a planetary gravity assisted flyby used to alter its speed and trajectory – in order to reach another celestial body.
Mariner 10 flew by Venus 40 years ago to enable the probe to gain enough speed and alter its flight path to eventually become humanity’s first spacecraft to reach the planet Mercury, closest to our Sun.
Indeed it was the first spacecraft to visit two planets.
During the flyby precisely four decades ago, Mariner 10 snapped its 1st close up view of Venus – see above.
From that moment forward, gravity assisted slingshot maneuvers became an extremely important technique used numerous times by NASA to carry out planetary exploration missions that would not otherwise have been possible.
For example, NASA’s twin Voyager 1 and 2 probes launched barely three years later in 1977 used the gravity speed boost to conduct their own historic flyby expeditions to our Solar Systems outer planets.
Mariner 10’s Mercury.

Without the flyby’s, the rocket launchers thrust by themselves did not provide sufficient interplanetary speed to reach their follow on targets.
NASA’s Juno Jupiter orbiter just flew back around Earth this past October 9, 2013 to gain the speed it requires to reach the Jovian system.
The Mariner 10 probe used an ultraviolet filter in its imaging system to bring out details in the Venusian clouds which are otherwise featureless to the human eye – as you’ll notice when viewing it through a telescope.
Venus surface is completely obscured by a thick layer of carbon dioxide clouds.
The hellish planet’s surface temperature is 460 degrees Celsius or 900 degrees Fahrenheit.

Following the completely successful Venus flyby, Mariner 10 eventually went on to conduct a trio of flyby’s of Mercury in 1974 and 1975.
It imaged nearly half of the planets moon-like surface, found surprising evidence of a magnetic field, discovered that a metallic core comprised nearly 80 percent of the planet’s mass, and measured temperatures ranging from 187°C on the dayside to minus 183°C on the nightside.
Mercury was not visited again for over three decades until NASA’s MESSENGER flew by and eventually orbited the planet – and where it remains active today.
Mariner 10 was launched on Nov. 3, 1973 from the Kennedy Space Center atop an Atlas-Centaur rocket.

Ultimately it was the last of NASA’s venerable Mariner planetary missions hailing from the dawn of the Space Age.
Mariner 11 and 12 were descoped due to congressional budget cuts and eventually renamed as Voyager 1 and 2.
The Mariner 10 science team was led by Bruce Murray of the Jet Propulsion Laboratory (JPL), Pasadena, Calif.
Murray eventually became the Director of JPL. After he passed away in 2013, key science features on Martian mountain climbing destinations were named in his honor by the Opportunity and Curiosity Mars rover science teams.

The first launch of February 2014 worldwide is about to light up the night skies over the Baikonur Cosmodrome in Kazakhstan, with the launch of a Soyuz-U rocket carrying the uncrewed Progress M-22M spacecraft to the ISS. You can watch the launch live here, as well as the “fast-track” docking just 5 hours and 58 minutes later.
Progress will be carrying 2.8 tons of fuel, oxygen, supplies and experiments to the International Space Station. This will be the 54th Progress flight to the International Space Station since the first Progress launch to the station in 2000.
The launch is set to occur at 16:23:33 Universal Time or 11:23:33 AM EST. NASA TV will go live with the launch at 11:00 AM EST/16:00 UT, and TV Tsenki will also broadcast video from the pad just prior, though the broadcast frequently its sans audio.
Progress is also on a four orbit “fast-track” launch headed to the International Space Station. Tune in to NASA TV at 5:00 PM EST/22:00 UT later today, and you’ll be able to catch the docking of the Progress spacecraft to the Pirs module of the ISS as well. Docking is set to occur at 5:25 PM EST/22:25 UT over the North Atlantic Ocean.
Fun fact: Neil Armstrong still holds the record for the fastest journey from liftoff to docking at 5 hours and 33 minutes during Gemini 8 way back in 1966.
Update: ISS Astros indeed report during the live broadcast of the launch of Progress M-22M on NASA TV today of catching sight of the first stage of the Soyuz-U at liftoff… we’ll post any pics if and when they surface.
Progress M-20M undocked from the same Pirs compartment earlier this week on Monday in order to make way for the arrival of Progress M-22M. Progress M-20M is still in orbit, and is slated for a fiery destructive reentry on February 11th over the South Pacific. The long span between undocking and reentry for Progress M-20M allows for experiments on the spacecraft’s attitude control system to be carried out by ground controllers.

This also marks the start of a busy 2014 season at the International Space Station. On March 1st, SpaceX continues its contract to resupply the station with the launch of a Falcon 9 rocket with its fifth Dragon capsule making its third operational delivery to the station on CRS-3. Then later in March on the 12th, Expedition 38 crewmembers Oleg Kotov, Sergey Ryazansky, and NASA astronaut Michael Hopkins will return to Earth aboard Soyuz TMA-10M. The next crewed launch headed to the International Space Station are Expedition 39 cosmonauts Alexander Skvortsov, Oleg Artemyev, and NASA astronaut Steve Swanson launching from Baikonur on March 26th on Soyuz TMA-12M.
Progress M-22M is ultimately slated to undock from the Pirs module of the International Space Station on April 7th for a destructive reentry over the South Pacific. Three additional SpaceX launches utilizing Dragon capsules and two more launches of Orbital Science’s Cygnus cargo spacecraft will be conducted in 2014, as well as visits by the European Space Agency’s ATV-5 Georges Lemaitre in June and JAXA’s HTV-5 in July.
And another launch from the Baikonur Cosmodrome is coming right up on Valentine’s Day, February 14th, with the liftoff of an International Launch Services Proton rocket carrying the Turksat 4A satellite. The launch will be carried live via the ILS website and is slated for 21:09 UT/4:09 PM EST.
And though these are all standard resupply missions to the International Space Station, spaceflight is anything but routine. Avid trackers of live launches will remember the Progress M-12M spacecraft that was lost shortly after launch back in August 2011. To date, Progress M-12M was the only supply craft that failed to reach the International Space Station. Progress M-12M impacted in the Choisk Region of Russia’s Altai Republic in the Far East. The RD-0110 engine began to experience a flight anomaly just over five minutes after launch, causing the flight computer to execute a termination of thrust. Progress M-12M was the first loss of a Progress spacecraft since the start of the program in 1978. Ironically, Progress M-12M carried among its cargo manifest 10 paintings made by the son of Russian artist Alesandr Shilov said to be for “the psychological support of the crew…” There’s also a small cottage industry in Siberia east of Russian launch sites in salvaging rocket parts and boosters for scrap metal as they plummet from the sky.

It’s also possible to spot these spacecraft from your backyard as they arrive and depart from the International Space Station. We caught sight of Progress M-20M just last night, passing very near the waxing crescent Moon. Progress was about magnitude +1 when directly overhead, and was about 9 minutes ahead of the International Space Station. We’ve seen the Dragon, HTV, ATV spacecraft, as well as the U.S. Space Shuttle shortly after undocking from the International Space Station when it was in service. In fact, there’s a series of good passes of the ISS at dusk over the next few evenings for the southeastern United States, including a pass at ~6:58 PM EST tonight. Progress M-20M should be about 20 minutes ahead of the station at this point, assuming, of course, it hasn’t maneuvered in its orbit as a part of ongoing thruster control experiments.
We’ll be checking those final orbital corrections just prior to the pass tonight, as well as tracking the launch and docking of Progress M-22M. Follow us on Twitter (@Astroguyz) for further updates.
Be sure to catch all the action at Baikonur and in low Earth orbit today, both online and overhead!

Facing a fire in space? It’s among the most catastrophic situations possible, according to NASA, so the agency spends a lot of time thinking of what to do. Here’s what you do with NASA training: Don a mask, grab an emergency book, and head quickly but calmly to the nearest control post to plot an attack.
This is presumably what is happening in the recent picture above, where Alexander Gerst (from the European Space Agency, on the left) and NASA’s Reid Wiseman are doing a fire drill on the ground.
Astronauts practice emergency procedures so often that their first instinct is to go to the procedures, Gerst said in a previous Universe Today interview. “They sink in and become a memorized response or a natural reaction,” he said in August. And in his case, Gerst has training from a previous career that would come in handy if a fire broke out on the International Space Station.
Gerst was a volunteer firefighter when he was attending school, and although Expedition 40/41 this year will be his first spaceflight, he’s well-used to extreme environments: he also has done science in Antarctica, where researchers are essentially responsible for themselves for months at a time.
NASA strives to make the fire training as real as possible to keep astronauts on their toes, including creative combinations of smoke machines. Gerst said the agency won’t go to extremes, however: “We don’t light our modules on fire,” he said.
Check out more about emergency training in this past Universe Today article, which also explains the difference between fighting a fire on the space station and dealing with one in a Soyuz spacecraft. Gerst and Reid (both rookie astronauts) and Russian astronaut Maxim Suraev (who was on Expeditions 21 and 22) are supposed to head into space in May.

In between preparing to be Japan’s first commander of the orbiting complex, JAXA Expedition 38 astronaut Koichi Wakata has tweeted at least one picture a day showing the view out the window and activities that he’s working on. It’s hard to pick favorites, but here are some of the best ones of the past week or so.

See below complete 6 wheel mosaic and ‘Dingo Gap’ dune alternate route mosaic plus 3-D view[/caption]
Continuing wheel damage from hoards of sharp edged Martian rocks are forcing engineers to seek a smoother pathway forward – potentially through a treacherous dune field – for NASA’s Curiosity rover on the jagged rock strewn road to Mount Sharp, her primary science destination.
Ever since rover engineers noticed holes and tears to the robots six aluminum wheels this past fall and winter 2013, the team has been photographing the wheels much more frequently and carefully assessing their condition. See our mosaics above and below.
Curiosity’s handlers are now considering diverting the SUV-sized robot to an alternate path crossing into a dune field and the valley beyond that entails traversing through much smoother Martian terrain to reach a highly desirable and nearby science destination called “KMS-9.”
Newly received images taken by the robot only on Friday, Jan. 31, reveal a very significant ragged looking puncture at least 2 to 3 inches (5 to 8 cm) in length and a inch or so (3 cm) wide that’s bent back to the inside of the left front wheel.

Unfortunately, the fields of rough Red Planet rocks have not been a blessing to the 1 ton behemoth.
See our new underbelly mosaic view of Curiosity’s holy wheels (above and below) snapped on Jan. 31, (Sol 529), that’s aimed at the interior and which vividly shows the extent of the injury to the 20 inch diameter wheel.

The rate of wheel damage has picked up dramatically as the driving pace accelerated across the rugged, rock filled Martian terrain over the past six months and put over 4.89 kilometers (3.04 mi.) on the odometer to date since the nailbiting August 2012 landing.
The mega robot is now standing at the edge of the dune field by the picturesque entrance known as the “Dingo Gap” after driving another 865 feet (264.7 meters) during January 2014.
You can see the increased damage resulting from the past months drive by comparing the new Sol 529 view with our underbelly mosaic from Sol 490 in December 2013.

However, the dune cutting across “Dingo Gap” measures about 3 feet (1 meter) in height.
Look at this 3-D “Dingo Gap” mosaic view from NASA and you can judge for yourself the choices the team faces.
Curiosity’s 3-D View Past Tall Dune at edge of ‘Dingo Gap’
This stereo mosaic of images from the Navigation Camera (Navcam) on Curiosity shows the terrain to the west from the rover’s position on Sol 528 (Jan. 30, 2014). The scene appears three dimensional when viewed through red-blue glasses with the red lens on the left. The view was taken just after Curiosity had arrived at the eastern edge of a location called “Dingo Gap.” A dune across the gap is about 3 feet (1 meter) high in the middle and tapered at south (left) and north (right) ends onto low scarps on either side of the gap. The rover team is evaluating possible driving routes on the other side before a decision whether the cross the gap. Credit: NASA/JPL-Caltech
So the team is evaluating whether that’s safe to bridge because they don’t want to get stuck in a hidden sand trap like the one that ultimately led to Spirit’s demise a few years back.
“The decision hasn’t been made yet, but it is prudent to go check,” said Jim Erickson of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., project manager for Curiosity, in a NASA statement.

“We’ll take a peek over the dune into the valley immediately to the west to see whether the terrain looks as good as the analysis of orbital images implies,” Erickson added, based on orbital images snapped by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO) circling overhead.
The team is also testing an array of different driving techniques to minimize the accumulation of wheel punctures, such as driving backwards or using only four of the six wheels to reduce the force of the wheels pushing against jagged rocks.
The “Dingo Gap” could offer a safer gateway to “KMS-9” along the journey of the rovers southwestwardly route to breathtaking foothills of Mount Sharp.

Dingo Gap lies between two low scarps and that is tapered off at both sides to the north and south.
KMS-9 is a potentially science rich target where the team hopes to conduct the first rock drilling operations since departing the Yellowknife Bay quadrant in July 2013.
The candidate drilling site lies only about half a mile (800 meters) away as the martian crow flies and features geology that’s appealing to the science team. But the roving routes under consideration are all much farther in actual distance.
“At KMS-9, we see three terrain types exposed and a relatively dust-free surface,” said science team collaborator Katie Stack of the California Institute of Technology, Pasadena.
Curiosity has already accomplished her primary goal of discovering a habitable zone on Mars that could support Martian microbes if they ever existed.
NASA’s rover Curiosity uncovered evidence that an ancient Martian lake had the right chemical ingredients, including clay minerals that could have sustained microbial life forms for long periods of time – and that these habitable conditions persisted on the Red Planet until a more recent epoch than previously thought.
As a result, the science team has shifted the missions focus to include the search for organic molecules – the building blocks of life as we know it – which may be preserved in the sedimentary rock layers of Mount Sharp.
“Really what we’re doing is turning the corner from a mission that is dedicated to the search for habitable environments to a mission that is now dedicated to the search for that subset of habitable environments which also preserves organic carbon,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology in Pasadena, said recently at the Dec. 2013 annual meeting of the American Geophysical Union (AGU).
Meanwhile, NASA’s Opportunity rover is exploring clay mineral outcrops by the summit of Solander Point on the opposite side of the Mars at the start of her 2nd Decade investigating the Red Planets mysteries.

The Columbia’s shuttle fiery end came as the STS-107 astronauts’ families were waiting runway-side for everyone to come home. NASA’s oldest space shuttle broke up around 9 a.m. Eastern (2 p.m. UTC) on Feb. 1, 2003, scattering debris along east Texas and nearby areas. Its demise was captured on several amateur video cameras, many of which were rebroadcast on news networks.
In the next four months, some 20,000 volunteers fanned out across the southwest United States to find pieces of the shuttle, coming up with 85,000 pieces (38% of the shuttle) as well as human remains. Meanwhile, investigators quickly zeroed in on a piece of foam that fell off of Columbia’s external tank and struck the wing. A seven-month inquiry known as the Columbia Accident Investigation Board eventually yielded that as the ultimate cause of the shuttle’s demise, although there were other factors as well.
The disaster killed seven people: Rick Husband, Willie McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark and Ilan Ramon (who was Israel’s first astronaut.) At a time when most shuttles were focused on building the International Space Station, this crew’s mandate was different: to spend 24 hours a day doing research experiments. Some of the work was recoverable from the crew’s 16 days in space.
Columbia’s demise brought about several design changes in the external tank as NASA zeroed in on “the foam problem.” NASA put in a new procedure in orbit for astronauts to scan the shuttle’s belly for broken tiles using the robotic Canadarm and video cameras; shuttles also flew to the International Space Station in such a way so that astronauts on station could take pictures of the bottom.
Return-to-flight mission STS-114 in July-August 2005 yielded more foam loss than expected. Then NASA found something. For a long time, workers at the Michoud Assembly Facility were blamed for improper foam installation after partial tests on external tanks, but an X-ray analysis on an entire tank (done for reasons that are explained in this blog post from then-shuttle manager Wayne Hale) revealed it was actually due to “thermal cycles associated with filling the tank.”
“Discovery flew on July 4, 2006; no significant foam loss occurred. I consider that to be the real return to flight for the space shuttle,” he wrote. “So were we stupid? Yes. Can you learn from our mistake? I hope so.”
