I can’t believe I never saw this before. This is the astronaut’s photography manual provided by Hasselblad for NASA astronauts. For those of you who didn’t grow up with a professional photographer for a father, Hasselblad cameras are really high quality, square-format film cameras that were used by astronauts throughout the NASA program – even on the Moon. (The astronauts use digital cameras now.)
Click here to access the guide (warning, it’s a PDF document).
So this is a guide written by Hasselblad giving astronauts special instructions on how to take the best photographs from space!
It’s actually a really solid photography guide, with great information on lenses, exposure settings, and camera technique. Any photographer could get some use out of it. But if you happen to be up in space, you’ll have everything you need to get that perfect shot.

On this somber occasion marking the 10th anniversary of the tragic events of 9/11, NASA’s Opportunity Mars rover has taken new images of itself on 9/11/11 showing a piece of metal recovered from the wreckage of the Twin Towers of the World Trade Center in New York City that was carried all the way to the planet Mars as a commemorative memorial to the innocent victims of the terrorist attacks of Sept 11, 2001.
On Sept. 11, 2011 (Martian Sol 2713), Opportunity snapped the memorial image above showing the Rock Abrasion Tool (RAT) and an American Flag – evoking the memory of the Twin Towers – from a slope on a Martian hill named Cape York which in turn is a segment of the rim of a gigantic crater named Endeavour.
Opportunity is still roving the red planet’s surface, nearly 8 years after safely landing on Jan 24, 2004. After an epic trek she recently arrived at the gigantic 14 mile wide Endeavour crater .
Opportunity took the new image of the RAT and 9/11 US Flag memorial on Mars on the exact day timed to coincide with the 10th anniversary of the attacks.
The image shows the arm extended for inspection of target on a rock called “Chester Lake”, according to NASA officials. Opportunity is driving in a northerly direction up the Cape York hill on her scientific expedition of the crater’s rim.

Both towers of the World Trade Center in New York City were destroyed by the terrorists on that terrible day and nearly 3000 precious people were killed during horrifying historic events that changed America and the World forever.
The RAT was built for NASA and both rovers by Honeybee Robotics which at that time was located less than a mile away from the WTC near the southern tip of Manhattan.
Steve Gorevan, the founder and chairman of Honeybee and a member of the rover science team, told me in a past interview that he was on his way to work and out on the city streets within a few blocks of the Twin Towers when he suddenly heard the sounds of the jet engines just before the first tower was struck.
Gorevan and the Honeybee employees watched the tragic events unfold from their company’s offices and rooftop the rest of the day. Following the terror attacks, Gorevan said access to Honeybee was restricted for weeks and the firm was on a tight deadline to deliver the RAT’s to NASA and the Jet Propulsion Laboratory in California where the rovers were being assembled.
The idea for somehow placing a Martian memorial on the rovers was presented. Gorevan told me that he was able to secure metallic pieces from the WTC wreckage through the Office of the then NYC Mayor Rudy Guiliani a few weeks after the attacks.

Aluminum shards were delivered by the Mayor’s office to Honeybee along with a note indicating their authenticity. These were soon fashioned into an aluminum shield that was placed on each RAT along with a US Flag. The shield serves as a cable guard.
Gorevan says the twin towers memorial was purposely kept quiet for some time until well after both rovers landed out of respect for the victims’ families.
Opportunity is healthy and continuing her exploration of Endeavour crater which harbors geologic formations and rocks unlike any previously investigated by either of the Mars Exploration (MER) rovers.
Along the rim of Endeavour crater rover scientists hope to discover and analyze clay minerals which formed in pH neutral water billions of years ago and a habitable environment much more favorable to the formation of life compared to all the other spots studied by either rover thus far.
Both rovers far exceeded their original 90 days warranties with many years of added bonus time for science exploration.

These days, nearly every game company is trying to get their fingers in the MMORPG (Massively Multiplayer Online Role Playing Game) pie. Given the past successes of games like Ultima Online and Everquest and the current success of games like EVE Online and World of Warcraft, it’s no surprise that companies want try to create the next “killer app” of the MMORPG market.
One such game company that will be launching a new game is the company partnered with NASA to develop a space-based MMORPG for the space agency. Having raised nearly $40,000 in pledged funding via kickstarter, the company aims to start beta testing their offering some time next year.
So what does this new MMORPG do differently that will attract and retain paying customers? What makes Astronaut: Moon, Mars and Beyond different from say, EVE Online, Star Trek Online, or Star Wars Galaxies?
When a game developer becomes associated with a “big-name” property, expectations from both fans and developers can be quite high. Despite securing a license to create a game based on the Stargate franchise, a game development company never released the game and eventually ended up in bankruptcy. Star Trek Online, despite being one of the most anticipated MMORPG franchises went through two developers and when finally released had less than stellar sales. Of course, many fans of MMORPG’s are all too familiar with the myriad issues that plagued Star Wars Galaxies.
Not all online games are destined for failure. Some games build up players steadily over time and retain an extremely loyal fan base. In some cases, “slow and steady wins the race” is a reality for some game companies. So, what does it take to build a successful online game franchise?

In the case of the upcoming NASA MMORPG, Daniel Laughlin, project manager of NASA’s Learning Technologies cited research over the past decade indicating that games have tremendous potential to enhance learning. Laughlin stated, “The goal of the MMO project is to tap into the power of games to inspire and promote learning specifically in areas of science, technology, engineering and mathematics (STEM)”. Laughlin also added, “Based on the existing literature as well as my own experiences gaming, an MMO was the logical choice for a game project for NASA.”
What Laughlin believes to be of benefit to his idea is that a MMO gives the ability to continually update, adjust and expand a game – keeping players engaged over long periods of time.
Laughlin also mentioned the success of a NASA proof-of-concept game, Moonbase Alpha, as an encouraging sign of interest in a NASA-themed MMORPG, citing over 400,000 downloads. Laughlin also added “It is short proof of concept piece. Just a 20 minute mission, but it was built to prove to NASA that we could build a commercial quality game that uses NASA content – the lunar architecture – and is fun and inspirational.”

How does a promising proof-of-concept demo become a full-fledged online game?
Laughlin’s office solicited development partners to build the game under a non-reimbursable space act agreement (Meaning NASA is partnered with the game developer, but no funds change hands). The Astronaut: Moon, Mars and Beyond team was selected through a competitive process and has signed an agreement with NASA. The development team has to raise development funds on their own and NASA will provide subject matter experts along with education and evaluation experts to assist the team. Currently, the development team has raised nearly $40,000 via their kickstarter page.

Khal Shariff, CEO of Project Whitecard is equally optimistic about Astronaut: Moon, Mars and Beyond, stating, “We view this project as an almost sacred opportunity to engage new and current generations of science fans, those who are forever looking outward, with a vision for space exploration.”
When asked specifically about the fund raising efforts via Kickstarter, Shariff mentioned “It means all of the world to the people making this project happen, and it’s a hell of a deal, especially when you see that a $30 bid will send two licenses to a school and one to yourself.” Shariff also added, “More than this, it shows that Astronaut: Moon, Mars and Beyond, has honest, people-driven roots and will succeed or fail on its own merits.”

Shariff’s goal is a very solid game mechanic that rewards players for competing in areas of STEM learning and mentioned that one essential gameplay mechanic is a combination of gear and crafting. One other game play mechanic of quests are standard fare in many online games. In the case of Astronaut: Moon, Mars and Beyond, the quests are missions that fit into the larger storyline. Shariff was tight-lipped as to what, if any protagonists are present in the game, stating: “We have protagonists in the game, and I won’t say much about them, because I don’t want to spoil the opening scene of Chapter One.”
On the topic of chapters, Shariff mentioned plans for a future expansion to allow manned travel to destinations beyond Mars and the asteroid belt, even though in first chapter, players will have visited said destinations with unmanned missions.
Based on information presented by the development team, it does appear they will be putting forth considerable effort to fulfill Laughlin’s goal of a fun, educational and infinitely playable game. Shariff concluded with: “We want you to sit down and curl up with one session and have a feeling like you had when you read the best short science fiction stories, especially like those of Clarke. There is plenty of adventure to plumb.”

[/caption]This past December the White House directed the National Academies to review how many astronauts that NASA actually needed to conduct its operations in the post-shuttle era. New findings in a new report are showing that rather than the space agency having too many astronauts – it will have too few to meet mission objectives. The National Research Council (NRC) has released a report showing that NASA is entering into a period where low numbers of qualified astronauts will affect the agency’s ability to conduct human space flight operations.
NASA once had a strong, stable astronaut corps but the agency has slowly but surely saw those numbers dwindle. In 1999 NASA had 150 astronauts today it has 61 – with more leaving the space agency every month. NASA needs to have a stable corps of space flyers for not only International Space Station operations but also to help develop the Orion Multi-Person Crew Vehicle (MPCV).
With the shuttle program over and the fleet of orbiters on their way to museums, many astronauts are opting to leave the space agency. Photo Credit: Jason Rhian
Moreover NASA needs its astronaut corps to remain stable so as to maintain its agreements with the Russian Federal Space Agency, European Space Agency, Japanese Aerospace Exploration Agency and Canadian Space agency. Fewer astronauts weakens NASA’s ability to fulfill operations that are required under these arrangements.
NASA is losing astronauts at approximately the rate of one every two months. If this exodus is allowed to continue the agency’s ability to conduct normal operations will be dramatically impaired. The NRC report highlights many of the nuances that space flight requires – most of which are missed when one considers space flight. Ground operations, emergency response, training and other elements that are involved with crewed space flight operations.
Astronaut Mark Kelly, who commanded the final flight of the space shuttle Endeavour has announced that he will leave NASA effective Oct. 1, the commander of STS-133, the final flight of Discovery, has already departed the space agency. Photo Credit: Jason Rhian
For many astronauts however the appeal of working for the space agency is fading. NASA no longer has clear-cut objectives as it once did. In 2004 plans were announced for NASA to go to the Moon, Mars and then other points in the solar system after the shuttle was retired. In 2010 NASA had the so-called ‘Vision for Space Exploration’ cancelled and the space agency was directed to assist commercial entities in developing technology to reach low-Earth-orbit. It is hoped that once these firms become viable NASA will be freed to fly to an asteroid and then Mars sometime in the 2030s.
NASA is experiencing what some might call a “brain drain” not only are astronauts departing the agency in large numbers – so too are other NASA officials. In recent months NASA’s Chief Technologist Bobby Braun, Safety Chief Bryan O’Connor and the Associate Administrator for Exploration Douglas Cooke (who has been with NASA for 38 years) have either left NASA or signaled their intent to do so.

Writing a dictionary is not the same as writing a novel. While it might seem difficult to mess up a dictionary, even one with terminology that is as complicated as that used within the space industry – getting it right can be challenging. For those that follow space flight having such a dictionary can be invaluable. While A Dictionary of the Space Age does meet the basic requirements easily it fails somewhat in terms of its comprehensiveness.
When normal folks, even space enthusiasts watch launches and other space-related events (EVAs, dockings, landings and such) there are so many acronyms and jargon thrown about – that it is extremely hard to follow. With A Dictionary of the Space Age on hand, one can simply thumb through and find out exactly what is being said, making it both easier to follow along and making the endeavor being witnessed far more inclusive. That is as long if you are only looking for the most general of terms. The book is far from complete – but given the complex nature of the topic – this might not have been possible.
Crewed, unmanned, military space efforts and satellites – all have key terms addressed within the pages of this book.
The book is published by The Johns Hopkins University Press and was compiled and written by aerospace expert Paul Dickson. One can purchase the book on the secondary market (Amazon.com) for around $12 (new for around $25). The dictionary also has a Kindle edition which is available for $37.76. Dickson’s previous works on space flight is Sputnik: The Shock of the Century.
Weighing in at 288 pages, the book briefly covers the primary terms used within the space community. In short, if you are interested in learning more about space flight – or wish to do so – this is a good book for you.

Video caption: NASA’s twin GRAIL spacecraft blast off atop a Delta II Heavy booster at 9:08 a.m. EDT on Saturday, September 10, 2011 from Cape Canaveral, Florida, on a mission to explore the moon in unprecedented detail.
Be sure to check out these awesome launch videos showing the Delta II Heavy rocket blasting off with NASA’s GRAIL Lunar Gravity Mapper twins on a “Journey to the Center of the Moon” – as shot by NASA and others – on Sept. 10. from Pad 17 B at Cape Canaveral Air Force Station in Florida at 9:08 a.m. EDT.
Thus began a circuitous 3.5 month voyage from the Earth to the Moon culminating in lunar orbit arrival on New Year’s Eve and Day 2012.
[/caption]
Liftoff of the $496 Million Gravity Recovery and Interior Laboratory (GRAIL) duo marked the last currently scheduled launch of a United Launch Alliance Delta II from Florida and also the last launch from Space Launch Complex 17. This was the 356th Delta launch overall since the first one in 1960. It was the 110th and final planned flight of a Delta II from Florida.
Watch the NASA GRAIL Launch Video as the 12 story Delta’s 1st stage liquid and solid engines ignite and the rocket’s explosive exhaust and fiery flames instantaneously and dramatically shoot out from below and are vented safely to the side through specially constructed flame ducts to protect the rocket.
Just after the 1 minute mark, the 6 ground lit solid rocket motors are jettisoned and dramatically tumble away from the first stage. Moment later comes the ignition of the three air-lit solid rocket motors.
This dramatic video was shot by Matt Travis of spacearium -from my viewing location with a hoard of photojournalists at Press Site 1 located inside Cape Canaveral Air Force Station.
Press Site 1 is just 1.5 miles away from Pad 17B. It offers the closest and best view of the mighty Delta II rocket which stands 128 feet tall and generates some 1.3 million pounds of liftoff thrust.
Watch this video for post-launch commentary from NASA’s Delta II Launch manager Tim Dunn from the Mission Director’s Center.

The GRAIL Launch video below was taken from Jetty Park Pier, about 2.9 miles south of Pad 17B and shows a completely different perspective from across the waterway of Port Canaveral.
I watched the unforgettable launch of Dawn five years ago from Jetty Park Pier.
Jetty Park and the beaches along Cape Banaveral and Cocoa Beach have been the best place for the public to view Delta rocket launches.
Thousands of spectators lining the Florida Space Coast were absolutely thrilled to witness the historic launch of GRAIL on the final Delta II booster from Florida on a gorgeous morning.
GRAIL’s primary science objectives during the 82 day mission are to determine the structure of the lunar interior, from crust to core, and to advance understanding of the thermal evolution of the moon and apply that to the other rocky bodies in our solar system.
Check this short NewBlast Video summary of GRAIL’s launch and objectives from Spaceflight Now
Many of NASA’s recent science missions have launched aboard Delta II rockets, including the outstandingly successful Spirit and Opportunity Mars rovers, Dawn Asteroid Orbiter, MESSENGER Mercury orbiter and Stardust and Deep Impact comet spacecraft.
Congratulations to everyone on the GRAIL team for a superb performance !

NASA renewed its focus on ground breaking science today with the thunderous blastoff of a pair of lunar bound spacecraft that will map the moons interior with unparalled precision and which will fundamentally alter our understanding of how the moon and other rocky bodies in our solar system – including Earth – formed and evolved over 4.5 Billion years.
Today’s (Sept. 10) launch of the twin lunar Gravity Recovery and Interior Laboratory (GRAIL) spacecraft atop the mightiest Delta II rocket from Cape Canaveral Air Force Station in Florida at 9:08 a.m. EDT was a nail biter to the end, coming after a two day weather delay due to excessively high upper level winds that scrubbed the first launch attempt on Sept. 8, and nearly forced a repeat cancellation this morning.
Liftoff of the nearly identical GRAIL A and B lunar gravity mappers from Space Launch Complex 17B took place on the second of two possible launch attempts after the first attempt was again waived off because the winds again violated the launch constraints.

After the final “GO” was given, the Delta II Heavy booster suddenly roared to life and put on a spectacular show spewing smoke, flames and ash as it pushed off the pad and shot skywards atop a rapidly growing plume of exhaust and rumbling thunder into a nearly cloudless sky.
The solar powered dynamic duo were propelled to space by the last ever Delta II rocket slated to depart Earth from Cape Canaveral, Florida. After more than 50 years of highly reliable service starting in 1960, the venerable Delta II family will be retired after one final launch in October from Vandenberg Air Force Base in California.
GRAIL and Delta II rocket soar to space.

On this special occasion the media were allowed to a witness the launch from Press Site 1 – a location just 1.5 miles away from the pad with a gorgeous and unobstructed view to the base of the pad which magnified the tremendous roar of the rocket engines.
“Since the earliest humans looked skyward, they have been fascinated by the moon,” said GRAIL principal investigator Maria Zuber from the Massachusetts Institute of Technology in Cambridge. “GRAIL will take lunar exploration to a new level, providing an unprecedented characterization of the moon’s interior that will advance understanding of how the moon formed and evolved.”

The spacecraft separation and deployment of the solar arrays worked exactly as planned, the mission team reported at a post launch briefing for reporters. Both probes are power positive and healthy.
GRAIL A and B are now speeding towards the moon on a low energy path that will take about 3.5 months compared to just three days for the Apollo astronauts. The slower and longer path covering more than 2.5 million miles (4 million kilometers) enables the spacecraft to use a smaller engine and carry less fuel for the braking maneuver required to place the probes into a polar elliptical orbit when they arrive at the moon about 25 hours apart on New Year’s Eve and New Year’s Day 2012.
“Our GRAIL twins have Earth in their rearview mirrors and the moon in their sights,” said David Lehman, GRAIL project manager at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. “The mission team is ready to test, analyze and fine-tune our spacecraft over the next three-and-a-half months on our journey to lunar orbit.”
During the 82 day science phase, the primary objective of is to study the moons interior from crust to core and map its gravity field by 100 to 1000 times better than ever before. GRAIL A and GRAIL B will fly in tandem formation in near circular polar orbit at an altitude of some 50 km above the lunar surface as the moon rotates beneath three times.

The mission will provide unprecedented insight into the structure and composition of moon from crust to core, unlock the mysteries of the lunar interior and advance our understanding of the thermal evolution of the moon that can be applied to the other terrestrial planets in our solar system, including Mercury, Venus, Earth and Mars.

A decade ago, the 9/11 attacks killed close to three thousand people and with the chaos that ensued many more were left wondering what was going on, whether-or-not their loved ones were still alive – or what was coming next. One man in particular was more isolated than the rest of his fellow citizens on that horrific day – he was forced to watch, some 240 miles above the face of the planet – as his nation came under attack.
Frank Culbertson Jr. was the Expedition 3 Commander on the International Space Station when Islamic radicals slammed two planes into the World Trade Center in New York City and a third into the Pentagon in Washington D.C. A fourth hijacked plane, whose target was believed to be the Capitol Building in Washington D.C., was prevented from reaching its destination by passengers. The terrorists on board crashed that plane, United 93, near Shanksville, Pennsylvania.
“I think like most Americans, at first I did not know what was happening – I just knew that it was bad,” said Culbertson referring to the attacks. “It was very painful; it was like seeing a wound in the side of your country, your family and your friends.”
Frank Culbertson was like most Amercans on 9/11 shocked, horrified - and more than anyone else in the world - isolated. Photo Credit: NASA.gov
Culbertson’s crew mates, both Russian, were Soyuz Commander Vladimir Deshurov and Flight Engineer Mikhail Tyurin. They offered all the support they could. Tyurin went so far as to prepare Culbertson’s favorite Borscht dinner that evening. Both of them also gave him time, time to understand and come to terms with what had happened. Russian ground controllers also worked to be supportive of Culbertson during this period. Russia’s TsUP worked to uplink information to Culbertson with whatever information they could when U.S. assets were unable to do so.
Age-wise, the ISS was still a somewhat new enterprise at the time, it had only hosted a crew for about a year – but it was already showing that people from different nations, some of whom had been hostile to one another just a short time before – could work together.
Culbertson initially was not comfortable with expressing his thoughts and feelings about 9/11. With time however; he has shared some of his thoughts regarding that day. Through it all, Culbertson has decided to focus not on anger – but hope.
Culbertson's crew mates, both Russian, did whatever they could to support Culbertson as he watched the events of 9/11 unfold from orbit. Photo Credit: NASA
“I met a veteran at Williamsburg and once he found out what I did – he looked at me and said that what is happening on the International Space Station is one of the best things that we (the U.S.) were doing, we have to work internationally to find peaceful ways to solve our problems. It’s men and women like that, the young people that are in harm’s way working to prevent events like 9/11 from taking place – that are the real heroes.”
Culbertson found even more hope when he talked to the children who were close to the attacks when they occurred.
“I had the privilege of talking to a school that was just a couple blocks away from Ground Zero and meet those kids and teachers in person. They were close to Ground Zero – but they were optimistic about the future – and as they are our future – I think we are in good hands.”

NASA’s Gravity Recovery and Interior Laboratory (GRAIL) moon mapping twins and the mighty Delta II rocket that will blast the high tech physics experiment to space on a lunar science trek were magnificently unveiled in the overnight darkness in anticipation of a liftoff that had originally been planned for the morning of Sept. 8.
Excessively high upper level winds ultimately thwarted Thursday’s launch attempt.
NASA late today has just announced a further postponement by another day to Saturday Sept. 10 to allow engineers additional time to review propulsion system data from Thursday’s detanking operation after the launch attempt was scrubbed to Friday. Additional time is needed by the launch team to review the pertinent data to ensure a safe blastoff of the $496 Million GRAIL mission.
There are two instantaneous launch opportunities at 8:29:45 a.m. and 9:08:52 a.m. EDT at Cape Canaveral, eight minutes earlier than was planned on Sept. 8. The weather forecast for Sept. 10 still shows a 60 percent chance of favorable conditions for a launch attempt.

Despite a rather poor weather prognosis, the heavy space coast cloud cover had almost completely cleared out in the final hours before launch, the surface winds were quite calm and we all expected to witness a thunderous liftoff. But measurements from weather balloons sent aloft indicated that the upper level winds were “red” and violated the launch criteria.

As the launch gantry was quickly retracted at Launch Complex 17B on Sept. 7, the Delta was bathed in xenon spotlights that provided a breathtaking light show as the service structure moved a few hundred feet along rails.
The cocoon like Mobile Service Tower (MST) provides platforms to access the rocket at multiple levels to prepare the vehicle and spacecraft for flight. The MST also protects the rocket from weather and impacts from foreign debris.
The Delta II rocket stands 128 feet tall and is 8 feet in diameter. The first stage liquid and solid rocket fueled engines will generate about 1.3 million pounds of thrust.
During the Terminal Countdown, the first stage is fueled with cryogenic liquid oxygen and highly refined kerosene (RP-1).
GRAIL is an extraordinary first ever journey to the center of the moon that will — with its instruments from orbit — peer into the moons interior from crust to core and map its gravity field by 100 to 1000 times better than ever before. The mission employs two satellites flying in tandem formation some 50 km in near circular polar orbit above the lunar surface.
GRAIL A and B will perform high precision range-rate measurements between them using a Ka-band instrument. The mission will provide unprecedented insight into the formation and thermal evolution of the moon that can be applied to the other rocky planets in our solar system: Mercury, Venus, Earth and Mars.
After a 3.5 month journey to the moon, the probes will arrive about a day apart on New Year’s Eve and New Year’s Day 2012 for an 82 day science mapping phase as the moon rotates three times beneath the GRAIL orbit.

Another American rocket Era is about to end. The venerable Delta II rocket, steeped in history, will fly what is almost certainly its final mission from Cape Canaveral. And it will do so quite fittingly by blasting twin satellites to the moon for NASA on a unique path for a truly challenging mission to do “extraordinary science”.
On Sept. 8, the most powerful version of the Delta II, dubbed the Delta II Heavy, is slated to launch NASA’s duo of GRAIL lunar mappers on an unprecedented science mission to unlock the mysteries of the moons deep interior. There are two instantaneous launch windows at 8:37:06 a.m. and 9:16:12 a.m. EDT lasting one second each.
“GRAIL simply put, is a journey to the center of the moon,” said Ed Weiler, NASA Associate Administrator of the Science Mission Directorate in Washington,DC at a pre-launch briefing for reporters on Sept. 6.
“It will probe the interior of the moon and map its gravity field by 100 to 1000 times better than ever before. We will learn more about the interior of the moon with GRAIL than all previous lunar missions combined.”

“Trying to understand how the moon formed, and how it evolved over its history, is one of the things we’re trying to address with the GRAIL mission,” says Maria Zuber, principal investigator for GRAIL from the Massachusetts Institute of Technology. “But also, (we’re) trying to understand how the moon is an example of how terrestrial planets in general have formed.”
“GRAIL is a mission that will study the inside of the moon from crust to core,” Zuber says.

So far there have been 355 launches of the Delta II family, according to NASA’s Delta II Launch Manager Tim Dunn. The Delta II is built by United Launch Alliance.
“GRAIL is the last contracted Delta II mission to be launched from Complex 17. And it will be the 356th overall Delta to be launched. Complex 17 at the Cape has a proud heritage of hosting 258 of those 355 total Delta launches to date.
Hypergolic propellants have been loaded onto the 2nd stage after assessing all the preparations for the rocket, spacecraft, the range and facilities required for launch.
“The Launch Readiness Review was successfully completed and we can proceed with the countdown,” said Dunn.
The Delta II Heavy is augmented with nine larger diameter ATK solid rocket motors.
The Mobile Service Tower will be rolled back from the Delta II rocket tonight, starting at about 10:30 p.m. EDT depending on the weather.
The weather forecast for launch remains very iffy at a 60% percent chance of “NO GO” according to NASA and Air Force officials.
A launch decision will be made tomorrow morning Sept. 8 right after the weather briefing but before fueling begins at 6:30 a.m.
The weather forecast for rollback of the Mobile Service Tower tonight remains generally favorable. There is a 40% chance of a weather issue at 10:30 p.m. which drops to 30% after midnight. Tower rollback can be pushed back about 2 hours without impacting the countdown, says NASA.
Weather remains at 60% NO GO in case of a 24 hour delay but improves over the weekend. The team has about 42 days time in the launch window.
After entering lunar orbit, the two GRAIL spacecraft will fly in a tandem formation just 55 kilometers above the lunar surface with an average separation of 200 km during the three month science phase.
Stay tuned to Universe Today for updates overnight leading to liftoff at 8:37 a.m.

GRAIL Flying in Formation. Using a precision formation-flying technique, the twin GRAIL spacecraft will map the moon's gravity field. The mission also will answer longstanding questions about Earth's moon, including the size of a possible inner core, and it should provide scientists with a better understanding of how Earth and other rocky planets in the solar system formed. GRAIL is a part of NASA's Discovery Program.
