GODDARD SPACE FLIGHT CENTER, MD – The huge Sunshield test unit for NASA’s James Webb Space Telescope (JWST) has been successfully unfurled for the first time in a key milestone ahead of the launch scheduled for October 2018.
Engineers stacked and expanded the tennis-court sized Sunshield test unit last week inside the cleanroom at a Northrop Grumman facility in Redondo Beach, California.
NASA reports that the operation proceeded perfectly the first time during the test of the full-sized unit.
The Sunshield and every other JWST component must unfold perfectly and to precise tolerances in space because it has not been designed for servicing or repairs by astronaut crews voyaging beyond low-Earth orbit into deep space, William Ochs, Associate Director for JWST at NASA Goddard told me in an exclusive interview.

The five layered Sunshield is the largest component of the observatory and acts like a parasol.
Its purpose is to protect Webb from the suns heat and passively cool the telescope and its quartet of sensitive science instruments via permanent shade to approximately 45 kelvins, -380 degrees F, -233 C.
The kite-shaped Sunshield provides an effective sun protection factor or SPF of 1,000,000. By comparison suntan lotion for humans has an SPF of 8 to 40.

The extreme cold is required for the telescope to function in the infrared (IR) wavelengths and enable it to look back in time further than ever before to detect distant objects.
The shield separates the observatory into a warm sun-facing side and a cold anti-sun side.
Its five thin membrane layers also provides a stable thermal environment to keep the telescopes 18 primary mirror segments properly aligned for Webb’s science investigations.
JWST is the successor to the 24 year old Hubble Space Telescope and will become the most powerful telescope ever sent to space.
The Webb Telescope is a joint international collaborative project between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).
NASA has overall responsibility and Northrop Grumman is the prime contractor for JWST.
Webb will launch folded up inside the payload fairing of an ESA Ariane V ECA rocket from the Guiana Space Center in Kourou, French Guiana.
In launch configuration, the Sunshield will surround the main mirrors and instruments like an umbrella.
During the post launch journey to the L2 observing orbit at the second Sun-Earth Lagrange point nearly a million miles (1.5 million Km) from Earth, the telescopes mirrors and sunshield will begin a rather complex six month long unfolding and calibration process.
The science instruments have been mounted inside the ISIM science module and are currently undergoing critical vacuum chamber testing at NASA Goddard Space Flight Center which provides overall management and systems engineering.

The road to a comet isn't an easy one! Luckily Rosetta and Philae have a lot of help.
…and that time is now! ESA’s Rosetta spacecraft is just over a mere two weeks away from its arrival at Comet 67P/Churyumov-Gerasimenko (which has recently surprised everyone with its binary “rubber duckie” shape) and the excitement continues to grow — and rightfully so, since after ten years traveling through the Solar System Rosetta is finally going to achieve its goal of being the first spacecraft to orbit a comet!
As part of the “Are We There Yet” campaign to encourage public participation in this historic space exploration event, ESA has released the next installment of Rosetta’s story in adorable animated format. Check it out above, and feel free to fall in love with a solar-powered spacecraft.
Keep up with Rosetta’s journey on the ESA website here, and enter the #RosettaAreWeThereYet contest by sharing your photos here (you could win a trip to ESA’s Operations Center in Darmstadt, Germany in November for Philae’s landing party!)

NASA WALLOPS FLIGHT FACILITY, VA – The long delayed liftoff of an Orbital Sciences Corp. commercial Antares rocket on a cargo mission bound for the International Space Station (ISS) has been cleared for blastoff this Friday, July 11, from the Eastern shore of Virginia, following a thorough re-inspection of the two Russian built and US modified AJ26 engines that power the rocket’s first stage after the test failure of a different engine in May.
The critically important Aerojet Rocketdyne AJ26 engine re-inspection was mandated following the significant failure of another AJ26 engine during acceptance testing on May 22 at NASA’s Stennis Space Center in Mississippi to investigate any concerns and insure against an in flight failure.
NASA and Orbital Sciences are now targeting the Antares launch carrying the privately developed Cygnus resupply freighter on the Orb-2 mission from Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA’s Wallops Flight Facility, Virginia, on July 11 at 1:40 p.m. (EDT).
Universe Today was granted a visit to the Orbital Sciences Antares rocket integration facility at NASA Wallops recently as the engine re-inspection work was winding down. See my Antares/Cygnus Orb-2 rocket photos herein.

Aerojet engineers re-inspected the engines while they were still mated to the bottom of the Antares rocket and found them to be satisfactory for fight. No swap out was required.
The Cygnus cargo logistics spacecraft was then mated to the rocket on July 3 and will be rolled out to the Wallops launch pad on Wednesday morning at 8:30 a.m., July 9.
Late stow items including time sensitive science experiments will be packed aboard on Tuesday, July 8.
The launch window on July 11 opens at 1:40 p.m. for a duration of 5 minutes.
In the event of a delay for any reason the next available launch opportunity is July 12 at 1:14 p.m.
Until the first stage engine failure, this Antares rocket had been slated to blastoff on June 10 with the Cygnus cargo freighter on the Orb-2 mission which is the second of eight cargo resupply missions to the ISS under Orbital’s Commercial Resupply Services (CRS) contract with NASA.

The AJ26 rocket engine that failed in May was extensively damaged about halfway through the planned test aimed at qualifying the engine for an Antares flight scheduled for early next year.
“There was a test failure at Stennis on May 22,” Orbital Sciences spokesman Barry Beneski told Universe Today at that time. “Engineers are examining data to determine the cause of the failure.”
The failure occurred approximately 30 seconds into the planned 54-second test.
“It terminated prematurely, resulting in extensive damage to the engine,” Orbital said in a statement in May.
The pressurized Cygnus spacecraft will deliver 1,657 kg of cargo to the ISS including science experiments and instruments, crew supplies, food, water, computer equipment, spacewalk tools and student research experiments.

Cygnus will remain berthed at the station for 40 days.
For the return to Earth it will be loaded with approximately 1,346 kg of material for disposal upon atmospheric reentry.
The two stage Antares rocket stands 133 feet tall.
It takes about 10 minutes from launch until separation of Cygnus from the Antares vehicle.

Flight time to the ISS is approximately 3 days. An on time launch will result in Cygnus arrival at the ISS on July 15.
Station commander Steven Swanson of NASA and Flight Engineer Alexander Gerst of the European Space Agency (ESA) will grapple and berth Cygnus using the stations 57 foot-long robotic arm onto the Earth-facing port of the station’s Harmony module.
The Antares first stage is powered by a pair of liquid oxygen and kerosene fueled AJ26-62 engines that deliver a combined 734,000 pounds (3265 kilonewtons) of sea level thrust.
To date the AJ26 engines have performed flawlessly through a total of three Antares launches from NASA’s Wallops Flight Facility in Virginia starting in April 2013.
They measure 3.3 meters (10.9 feet) in height and weigh 1590 kg (3,500 lb.).
The AJ26 engines were originally known as the NK-33 and built during the 1960s and 1970s in the Soviet Union for their manned moon landing program.
Aerojet extensively modified, checked and tested the NK-33 engines now designated as the AJ26-62 to qualify them for use in the first stage Antares core, which is manufactured in Dnipropetrovsk, Ukraine by the Yuznoye Design Bureau and based on the Zenit launch vehicle.

Orbital Sciences was awarded a $1.9 Billion supply contract by NASA to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware for 8 flight to the ISS through 2016 under the Commercial Resupply Services (CRS) initiative.
The July mission marks the second operational Antares/Cygnus flight.
SpaceX has a similar resupply contract using their Falcon 9 rocket and Dragon cargo carrier and just completed their 3rd operational mission to the ISS in May.

Animation of Comet 67P/Churyumov-Gerasimenko as seen by Rosetta on June 27-28, 2014
This is really getting exciting! ESA’s Rosetta spacecraft (and the piggybacked Philae lander) are in the home stretch to arrive at Comet 67P/Churyumov-Gerasimenko in 34 days and the comet is showing up quite nicely in Rosetta’s narrow-angle camera. The animation above, assembled from 36 NAC images acquired last week, shows 67P/C-G rotating over a total elapsed time of 12.4 hours. No longer just an extra-bright pixel, it looks like a thing now!
The animation, although fascinating, only hints at the “true” shape of the comet’s nucleus. Reflected light does create a bloom effect in the imaging sensor, especially at such small resolutions, expanding the apparent size of the comet beyond its 4-by-4-pixel size. But rest assured that much, much better images are on the way as Rosetta gets closer and closer.
The spacecraft was about 86,000 km (53,440 miles) from 67P/C-G when the images were acquired. Since that time it has cut that distance in half, and by this weekend it will be less than 36,000 km (22,370 miles) from the comet. After more than a decade of traveling around the inner Solar System Rosetta is finally arriving at its goal! Click here to see where Rosetta is now.
Stay tuned for more exciting updates from Rosetta, and learn more about the mission below:
Diagram of Comet 67P/C-G compared to terrestrial landmarks (ESA)
Pretty darn big, I’d say.
The illustration above shows the relative scale of the comet that ESA’s Rosetta and Philae spacecraft will explore “up-close and personal” later this year. And while it’s one thing to say that the nucleus of Comet 67P/Churyumov-Gerasimenko is about three by five kilometers in diameter, it’s quite another to see it in context with more familiar objects. Think about it — a comet as tall as Mt Fuji!

At the time of this writing Rosetta is 35 days out on approach to Comet 67P/C-G, at a distance of about 51,000 km (31,700 miles) and closing. Three “big burn” maneuvers have already been performed between May 7 and June 4 to adjust the spacecraft’s course toward the incoming comet, and after smaller ones on June 18 and July 2 there are a total of five more to go. See details of Rosetta’s burn maneuvers here.
Luckily the remaining burns are relatively small compared to the first three, with the final being very brief, so any data contamination by Rosetta’s own exhaust shouldn’t become an issue once the spacecraft has established orbit in August.
Launched in March 2004, ESA’s Rosetta mission will be the first to orbit and land a probe on a comet, observing its composition and behavior as it makes its close approach to the Sun in 2015. Click here to see where Rosetta is right now.
Note: While 3-5 km seems pretty big (especially when stood on end) comet nuclei can be much larger, 10 to 20 km in diameter up to the enormous 40+ km size of Hale-Bopp. As comets go, 67P/C-G is fairly average. (Except that, come August, it will be the only comet with an Earthly spacecraft in tow!)

It’s no surprise that there is a lot of water in comets. The “dirty snowballs” (or dusty ice-balls, more accurately) are literally filled with the stuff, so much in fact it’s thought that comets played a major role in delivering water to Earth. But every comet is unique, and the more we learn about them the more we can understand the current state of our Solar System and piece together the history of our planet.
ESA’s Rosetta spacecraft is now entering the home stretch for its rendezvous with comet 67P/Churyumov-Gerasimenko in August. While it has already visually imaged the comet on a couple of occasions since waking from its hibernation, its instruments have now successfully identified water on 67P for the first time, from a distance of 360,000 km — about the distance between Earth and the Moon.
The detection comes via Rosetta’s Microwave Instrument for Rosetta Orbiter, or MIRO, instrument. The results were distributed this past weekend to users of the IAU’s Central Bureau of Astronomical Telegrams:
S. Gulkis, Jet Propulsion Laboratory, California Institute of Technology, on behalf of the Microwave Instrument on Rosetta Orbiter (MIRO) science team, reports that the (1_10)-(1_01) water line at 556.9 GHz was first detected in Comet 67P/Churyumov-Gerasimenko with the MIRO instrument aboard the Rosetta spacecraft on June 6.55, 2014 UT. The line area is 0.39 +/-0.06 K km/s with the line amplitude of 0.48 +/-0.06 K and the line width of 0.76 +/-0.12 km/s. At the time of the observations, the spacecraft to comet distance was ~360,000 km and the heliocentric distance of the comet was 3.93 AU. An initial estimate of the water production rate based on the measurements is that it lies between 0.5 x 10^25 molecules/s and 4 x 10^25 molecules/s.
Although recent images of 67P/C-G seem to show that the comet’s brightness has decreased over the past couple of months, it is still on its way toward the Sun and with that will come more warming and undoubtedly much more activity. These recent measurements by MIRO show that the comet’s water production rate is “within the range of models being used” by scientists to anticipate its behavior.

This August Rosetta will become the first spacecraft to establish orbit around a comet and, in November, deploy its Philae lander onto its surface. Together these robotic explorers will observe first-hand the changes in the comet as it makes its closest approach to the Sun in August 2015. It’s going to be a very exciting year ahead, so stay tuned for more!

NASA’s decade old Opportunity rover has reached a long sought after region of aluminum-rich clay mineral outcrops at a new Endeavour crater ridge now “named ‘Pillinger Point’ after Colin Pillinger the Principal Investigator for the [British] Beagle 2 Mars lander”, Prof. Ray Arvidson, Deputy Principal Investigator for the rover, told Universe Today exclusively. See above the spectacular panoramic view from ‘Pillinger Point’ – where ancient water once flowed billions of year ago.
The Beagle 2 lander was built to search for signs of life on Mars.
The Mars Exploration Rover (MER) team named the noteworthy ridge in honor of Prof. Colin Pillinger – a British planetary scientist at the Open University in Milton Keynes, who passed away at the age of 70 on May 7, 2014.
‘Pillinger Point’ is a scientifically bountiful place possessing both clay mineral outcrops and mineral veins where “waters came up through the cracks”, Arvidson explained to me.
Since water is a prerequisite for life as we know it, this is a truly fitting tribute to name Opportunity’s current exploration site ‘Pillinger Point’ after Prof. Pillinger.
See our new photo mosaic above captured by Opportunity peering out from ‘Pillinger Point’ ridge on June 5, 2014 (Sol 3684) and showing a panoramic view around the eroded mountain ridge and into vast Endeavour crater.
The gigantic crater spans 14 miles (22 kilometers) in diameter.
See below our Opportunity 10 Year traverse map showing the location of Pillinger Point along the segmented rim of Endeavour crater.
British planetary scientist Colin Pillinger with the Beagle 2 lander.
Pillinger Point is situated south of Solander Point and Murray Ridge along the western rim of Endeavour in a region with caches of clay minerals indicative of an ancient Martian habitable zone.
For the past several months, the six wheeled robot has been trekking southwards from Solander towards the exposures of aluminum-rich clays – now named Pillinger Point- detected from orbit by the CRISM spectrometer aboard NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – while gathering context data at rock outcrops along the winding way.
“We are about 3/5 of the way along the outcrops that show an Al-OH [aluminum-hydroxl] montmorillonite [clay mineral] signature at 2.2 micrometers from CRISM along track oversampled data,” Arvidson told me.
“We have another ~160 meters to go before reaching a break in the outcrops and a broad valley.”
The rover mission scientists ultimate goal is travel even further south to ‘Cape Tribulation’ which holds a motherlode of the ‘phyllosilicate’ clay minerals based on extensive CRISM measurements accomplished earlier at Arvidson’s direction.
“The idea is to characterize the outcrops as we go and then once we reach the valley travel quickly to Cape Tribulation and the smectite valley, which is still ~2 km to the south of the present rover location,” Arvidson explained.
Mars Express and Beagle 2 were launched in 2003, the same year as NASA’s twin rovers Spirit and Opportunity, on their interplanetary voyages to help unlock the mysteries of Mars potential for supporting microbial life forms.
Pillinger was the driving force behind the British built Beagle 2 lander which flew to the Red Planet piggybacked on ESA’s Mars Express orbiter. Unfortunately Beagle 2 vanished without a trace after being deployed from the orbiter on Dec. 19, 2003 with an expected air bag assisted landing on Christmas Day, Dec. 25, 2003.
In an obituary by the BBC, Dr David Parker, the chief executive of the UK Space Agency, said that Prof. Pillinger had played a critical role in raising the profile of the British space programme and had inspired “young people to dream big dreams”.

During his distinguished career Pillinger also analyzed lunar rock samples from NASA’s Apollo moon landing missions and worked on ESA’s Rosetta mission.
“It’s important to note that Colin’s contribution to planetary science goes back to working on Moon samples from Apollo, as well as his work on meteorites,” Dr Parker told the BBC.
Today, June 16, marks Opportunity’s 3696th Sol or Martian Day roving Mars – compared to a warranty of just 90 Sols.
So far she has snapped over 193,400 amazing images on the first overland expedition across the Red Planet.
Her total odometry stands at over 24.51 miles (39.44 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

In 1964 the European Launcher Development Organisation (ELDO) and the European Space Research Organisation (ESRO) were founded, on February 29 and March 20 respectively, marking the beginning of Europe as a major space power and player in the new international venture to explore beyond our planet. A decade later these two entities merged to become ESA, and the rest, as it’s said, is history.
The video above commemorates ESA’s service to the cooperation and innovation of European nations in space, and indeed the entire world with many of the far-reaching exploration missions its member states have developed, launched and maintained. From advanced communications and observational satellites to its many missions exploring the worlds of the Solar System to capturing the light from the beginning of the Universe, ELDO, ESRO, and ESA have pushed the boundaries of science and technology in space for half a century… and are inspiring the next generation to continue exploring into the decades ahead. So happy anniversary, ESA — I can only imagine what we might be looking back on in another 50 years!

Philae is awake… and taking pictures! This image, acquired last night with the lander’s CIVA (Comet nucleus Infrared and Visible Analyzer) instrument, shows the left and right solar panels of ESA’s well-traveled Rosetta spacecraft, upon which the 100-kilogram Philae is mounted.
Philae successfully emerged from hibernation on March 28 via a wake-up call from ESA.
After over a decade of traveling across the inner Solar System, Rosetta and Philae are now in the home stretch of their ultimate mission: to orbit and achieve a soft landing on comet 67/P Churyumov-Gerasimenko. It will be the first time either feat has ever been attempted by a spacecraft. Read more here.
