How to Fight for the “Fight for Space” Documentary

A graphic from "Fight for Space."

Can documentary films actually change the way people think about a topic? Films like “The Thin Blue Line,” “The Triumph of Will,” and “Harlan County USA” are definitely documentaries that swayed both local public opinion and world views on specific topics. Film producer Paul Hildebrandt is hoping his upcoming documentary film “Fight for Space” will not only help sway public opinion and inform people about space exploration but also help policymakers better understand NASA.

“This is a unique space documentary, as it covers the space program from a policy perspective,” Hildebrandt said, “looking at the detailed reasons why the NASA budget has been cut over the years, why certain decisions were made, and what the future of our human space flight effort looks like.”

Hildebrant and his team have been working on this film for several years (see our 2012 article about it) and are looking for the public’s help in raising $80,000 to complete the film and get it released. They have a goal of getting the film out by May 2015, and be able to show the film at limited theatrical screenings around the country, and have it ready for public television broadcast later this year. You can see the film’s trailer above, and here’s information on how you can help support this film on Kickstarter. Timing is critical: this Kickstarter wraps up on Feb. 1, 2015.

This isn’t a “feel good” look back at NASA’s accomplishments, but it does look at the past, present, and future of the US human spaceflight effort. Some issues that Hildebrant brings up in this film are likely to be controversial, if not hard-hitting. But many in the space community have expressed opinions about the lack of leadership, budgetary instability and a deficiency in project management for NASA. This film talks with many who have been in the middle of the successes, failures and issues at NASA, with the hopes of helping to “push the people of the world and the decision makers that govern them to look up at the stars instead of at our feet.”

“Our film asks, why in over 40 years haven’t we returned to the Moon, or sent humans onto Mars?,” says Hildebrandt. “We explore issues and we bring problems to light that always are not the most positive things to talk about. But it’s important to remember that NASA has been the only organization to send humans to the Moon, or a rover to Mars, or do many of the exciting things that make up our space program today. We love NASA, what it stands for, and all that it has done.”

Take a look at the trailer and information on Kickstarter and consider helping this film become a reality.

Falcon Heavy Rocket Launch and Booster Recovery Featured in Cool New SpaceX Animation

SpaceX released a cool new animation today, Jan. 27, showing an updated look at their Falcon Heavy rocket and plans for booster recovery. See below.

The Falcon Heavy is the brainchild of billionaire entrepreneur Elon Musk, SpaceX CEO and founder, and illustrates his moving forward with the firm’s next giant leap in spaceflight.

The rocket is designed to lift over 53 tons (117,00 pounds) to orbit and could one day launch astronauts to the Moon and Mars.

The commercial Falcon Heavy rocket has been under development by SpaceX for several years and the initial launch is now planned for later this year from Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.

The new rocket is comprised of three Falcon 9 cores.

The Falcon Heavy will be the most powerful rocket developed since NASA’s Saturn V rocket that hurled NASA’s Apollo astronauts to the Moon in the 1960s and 1970s – including the first manned landing on the Lunar surface by Neil Armstrong and Buzz Aldrin in July 1969.

Here is the updated animation of the SpaceX Falcon Heavy flight and booster recovery:

The video shows the launch of the triple barreled Falcon Heavy from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Then it transitions to the recovery of all three boosters by a guided descent back to a soft touchdown on land in the Cape Canaveral/Kennedy Space Center area.

SpaceX, headquartered in Hawthorne, CA, signed a long term lease with NASA in April 2014 to operate seaside pad 39A as a commercial launch facility for launching the Falcon Heavy as well as the manned Dragon V2 atop SpaceX’s man-rated Falcon 9 booster.

Launch Complex 39A has sat dormant for over three years since the blastoff of the final shuttle mission STS-135 in July 2011 on a mission to the International Space Station (ISS).

SpaceX is now renovating and modifying the pad as well as the Fixed and Mobile Service Structures, RSS and FSS. They will maintain and operate Pad 39A at their own expense, with no US federal funding from NASA.

When it does launch, the liquid fueled Falcon Heavy will become the most powerful rocket in the world according to SpaceX, generating nearly four million pounds of liftoff thrust from 27 Merlin 1D engines. It will then significantly exceeding the power of the Delta IV Heavy manufactured by competitor United Launch Alliance (ULA), which most recently was used to successfully launch and recover NASA’s Orion crew capsule on its maiden unmanned flight in Dec. 2014

SpaceX recently completed a largely successful and history making first attempt to recover a Falcon 9 booster on an ocean-going “drone ship.” The rocket nearly made a pinpoint landing on the ship but was destroyed in the final moments when control was lost due to a loss of hydraulic fluid.

Read my story with a SpaceX video – here – that vividly illustrates what SpaceX is attempting to accomplish by recovering and ultimately reusing the boosters in order to dramatically cut the cost of access to space.

The first solid rocket booster qualification motor for NASA’s mammoth new Space Launch System (SLS) rocket is aimed and ready to fire in a major ground test after NASA and ATK finished its installation at a test stand in Utah, and confirms that the pace of SLS development is gaining momentum.

The booster known as qualification motor, QM-1, is the largest solid rocket motor ever built and will be ignited on March 11 for a full duration static fire test by prime contractor ATK at the firms test facility in Promontory, Utah.

The two minute test firing of the full scale booster marks another major milestone in NASA’s ongoing program to assemble and launch the new SLS, which is the most powerful rocket ever built in human history.

The QM-1 booster is being conditioned to 90 degrees and the static fire test will qualify the booster design for high temperature launch conditions. It sits horizontally in the test stand and measures 154 feet in length and 12 feet in diameter and weighs 801 tons.

The five-segment booster will produce 3.6 million pounds of maximum thrust.

The first stage of the SLS will be powered by a pair of the five-segment boosters and four RS-25 engines that will generate a combined 8.4 million pounds of liftoff thrust and is designed to propel the Orion crew capsule to deep space destinations, including the Moon, asteroids and the Red Planet.

“With RS-25 engine testing underway, and this qualification booster firing coming up, we are taking big steps toward building this rocket and fulfilling NASA’s mission of Mars and beyond,” said SLS Program Manager Todd May.

“This is the most advanced propulsion system ever built and will power this rocket to places we’ve never reached in the history of human spaceflight.”

NASA’s goal is to launch humans to Mars by the 2030s.

The boosters and RS-25 engines were originally developed for NASA’s space shuttle program and are being modified and enhanced for NASA’s new SLS rocket.

The original shuttle-era boosters were made of four segments.

“Testing before flight is critical to ensure reliability and safety when launching crew into space,” said Charlie Precourt, vice president and general manager of ATK’s Space Launch division.

“The QM-1 static test is an important step in further qualifying this new five-segment solid rocket motor for the subsequent planned missions to send astronauts to deep space.”

The static fire test will collect data on 103 design objectives as measured through more than 534 instrumentation channels on the booster as it is firing. It is being preheated to 90 degrees Fahrenheit to measure the boosters performance at high temperatures and confirm it meets all necessary structural and ballistic requirements to launch astronauts.

The test will evaluate motor performance, acoustics, motor vibrations, nozzle modifications, insulation upgrades and avionics command and control performance. The full-scale motor test will further improve the safety, technology and knowledge of solid rocket motors, according to ATK.

The first SLS hot fire test of an RS-25 was successfully completed on Jan. 9 with a 500 second long firing on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, as I reported – here.

The SLS core stage is being built at NASA’s Michoud Assembly Facility in New Orleans.

On Sept. 12, 2014, NASA Administrator Charles Bolden officially unveiled the world’s largest welder at Michoud, that will be used to construct the core stage, as I reported earlier during my on-site visit – here.

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

Orion’s inaugural mission dubbed Exploration Flight Test-1 (EFT) was successfully launched on a flawless flight on Dec. 5, 2014 atop a United Launch Alliance Delta IV Heavy rocket Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

We’ve subsisted for months on morsels of information coming from ESA’s mission to Comet 67P/Churyumov-Gerasimenko. Now, a series of scientific papers in journal Science offers a much more complete, if preliminary, look at Rosetta’s comet. And what a wonderful and complex world it is.

Scientists have defined 19 regions on Comet 67P/Churyumov-Gerasimenko's nucleus grouped according to terrain. Each is named for an ancient Egytptian deity. Credits: ESA/Rosetta/MPS/OSIRIS Team/UPD/LAM/IAA/SSO /INTA/UPM/DASP/IDA

Each of the papers describes a different aspect of the comet from the size and density of dust particles jetting from the nucleus, organic materials found on its surface and the diverse geology of its bizarre landscapes. Surprises include finding no firm evidence yet of ice on the comet’s nucleus. There’s no question water and other ices compose much of 67P’s 10 billion ton mass, but much of it’s buried under a thick layer of dust.

Despite its solid appearance, 67P is highly porous with a density similar to wood or cork and orbited by a cloud of approximately 100,000 “grains” of material larger than 2 inches (5 cm) across stranded there after the comet’s previous perihelion passage. Thousands of tiny comet-lets!

“Robotic controllers let the CATS out of the bag!” So says NASA spokesman Dan Huot in a cool new NASA timelapse video showing in detail how CATS crawled around the space stations gangly exterior and clawed its way into its new home – topped off with a breathtaking view of our home planet that will deliver science benefits to us down below.

The CATS experiment was installed on the exterior of the International Space Station (ISS) via a first ever type of robotic handoff, whereby one of the stations robotic arms handed the rectangular shaped instrument off to a second robotic arm. Sort of like relays runners passing the baton while racing around the track for the gold medal.

In this case it was all in the name of science. CATS is short for Cloud Aerosol Transport System.

Ground controllers at NASA’s Johnson Space Center in Houston plucked CATS out of the truck of the recently arrived SpaceX Dragon cargo delivery vehicle with the Special Purpose Dexterous Manipulator (Dextre). Then they passed it off to a Japanese team of controllers at JAXA, manipulating the second arm known as the Japanese Experiment Module Remote Manipulator System. The JAXA team then installed CATS onto an external platform on Japans Kibo laboratory.

CATS is a new Earth Science instrument dedicated to collecting continuous data about clouds, volcanic ash plumes and tiny airborne particles that can help improve our understanding of aerosol and cloud interactions and improve the accuracy of climate change models.

The remote-sensing laser instrument measures clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere that directly impacts the global climate.

Data from CATS will be used to derive properties of cloud/aerosol layers at three wavelengths: 355, 532, 1064 nm.

Check out this cool NASA ‘Space to Ground’ video showing CATS installation

Video caption: NASA’s Space to Ground on 1/23/15 covers CATS Out of The Bag. This is your weekly update on what’s happening aboard the International Space Station. Got a question or comment? Use #spacetoground to talk to us.

All the movements were conducted overnight by robotic flight controllers on the ground. They installed CATS to an external platform on Japan’s Kibo lab module.

CATS is helping to open a new era on the space station research dedicated to expanding its use as a science platform for making extremely valuable remote sensing observations for Earth Science.

The CATS instrument is the fourth successful NASA Earth science launch out of five scheduled during a 12-month period. And it is the second to be installed on the exterior of the ISS, following ISS-RapidScat that was brought by the SpaceX CRS-4 Dragon.

The fifth launch — the Soil Moisture Active Passive satellite — is scheduled for Jan. 29 from Vandenberg Air Force Base in California.

CATS was launched to the station as part of the payload aboard the SpaceX Dragon CRS-5 cargo vessel bolted atop the SpaceX Falcon 9 for the spectacular nighttime blastoff on Jan. 10 at 4:47 a.m. EST from Cape Canaveral Air Force Station in Florida.

CATS was loaded in the unpressurized rear trunk section of Dragon.

President Obama gave a shout out to NASA Astronaut Scott Kelly and his upcoming 1 year mission to the International Space Station at the 2015 State of the Union address to the US Congress on Tuesday evening, Jan. 20, 2015.

Obama wished Kelly (pictured above in the blue jacket) good luck during his address and told him to send some photos from the ISS via Instagram. Kelly was seated with the First Lady, Michelle Obama, during the speech on Capitol Hill.

The TV cameras focused on Kelly and he was given a standing ovation by the Congress and the President.

Obama also praised Kelly’s flight and the recent Dec. 5, 2014, launch of NASA’s Orion deep space capsule as “part of a re-energized space program that will send American astronauts to Mars.”

Watch this video of President Obama hailing NASA and Scott Kelly:

Here’s a transcript of President Obama’s words about NASA, Orion, and Scott Kelly’s 1 Year ISS mission:

“Pushing out into the Solar System not just to visit, but to stay. Last month, we launched a new spacecraft as part of a re-energized space program that will send American astronauts to Mars. In two months, to prepare us for those missions, Scott Kelly will begin a year-long stay in space. Good luck, Captain and make sure to Instagram it.”

In late March, Astronaut Scott Kelly will launch to the International Space Station and become the first American to live and work aboard the orbiting laboratory for a year-long mission.

Scott Kelly and Russian Cosmonaut Mikhail Kornienko, both veteran spacefliers, comprise the two members of the 1 Year Mission crew.

Normal ISS stays last for about a six month duration.

No American has ever spent anywhere near a year in space. 4 Russian cosmonauts conducted long duration stays of about a year or more in space aboard the Mir Space Station in the 1980s and 1990s.

Together with Russian cosmonaut Gennady Padalka, Kelly and Kornienko will launch on a Russian Soyuz capsule from the Baikonur Cosmodrome as part of Expedition 44.

Kelly and Kornienko will stay aboard the ISS until March 2016.

They will conduct hundreds of science experiments focusing on at least 7 broad areas of investigation including medical, psychological, and biomedical challenges faced by astronauts during long-duration space flight.

A busy year of 13 space launches by rocket provider United Launch Alliance (ULA) in 2015 begins with a pair of blastoffs for the US Navy and NASA tonight and next week, emanating from both the US East and West Coasts.

The hefty manifest of 13 liftoffs in 2015 comes hot on the heels of ULA’s banner year in 2014 whereby they completed every one of the firm’s 14 planned launches in 2014 with a 100% success rate.

“What ULA has accomplished in 2014, in support of our customers’ missions, is nothing short of remarkable,” said ULA CEO Tory Bruno.

“When you think about every detail – all of the science, all of the planning, all of the resources – that goes into a single launch, it is hard to believe that we successfully did it at a rate of about once a month, sometimes twice.”

ULA’s stable of launchers includes the Delta II, Delta IV and the Atlas V. They are in direct competition with the Falcon 9 rocket from SpaceX founded by billionaire Elon Musk.

And ULA’s 2015 launch calendar begins tonight with a milestone launch for the US Navy that also marks the 200th launch overall of the venerable Atlas-Centaur rocket that has a renowned history dating back some 52 years to 1962 with multiple variations.

And tonight’s blastoff of the Multi-User Objective System (MUOS-3) satellite for the US Navy involves using the most powerful variant of the rocket, known as the Atlas V 551.

Liftoff of MUOS-3 is set for 7:43 p.m. EDT from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida. The launch window extends for 44 minutes and the weather outlook is very favorable. It will be carried live on a ULA webcast.

The second ULA launch of 2015 comes just over 1 week later on January 29, lofting NASA’s SMAP Earth observation satellite on a Delta II rocket from Vandenberg Air Force Base in California.

MUOS is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move, according to ULA.

This is the third satellite in the MUOS series and will provide military users 10 times more communications capability over existing systems, including simultaneous voice, video and data, leveraging 3G mobile communications technology.

ULA’s second launch in 2015 thunders aloft from the US West Coast with NASA’s Soil Moisture Active Passive mission (SMAP). It is the first US Earth-observing satellite designed to collect global observations of surface soil moisture.

SMAP will blastoff from Space Launch Complex 2 at Vandenberg AFB at 9:20 a.m. EST (6:20 a.m. PST) on ULA’s Delta II rocket.

“It goes without saying: ULA had a banner year,” Bruno said. “As we look ahead to 2015, we could not be more honored to continue supporting our nation in one of the most technologically complex, critical American needs: affordable, reliable access to space.”

ULA began operations in December 2006 with the merger of the expendable launch vehicle operations of Boeing and Lockheed Martin.

ULA’s Delta IV Heavy is currently the world’s most powerful rocket and flawlessly launched NASA’s Orion capsule on Dec. 5, 2014 on its highly successful uncrewed maiden test flight on the EFT-1 mission.

Overall, the 14-mission launch manifest in 2014 included 9 national security space missions, 3 space exploration missions, including NASA’s Orion EFT-1 and 2 commercial missions.

Beyond MUOS-3 and SMAP, the launch manifest on tap for 2015 also includes additional NASA science satellites, an ISS commercial cargo resupply mission as well as more GPS satellites for military and civilian uses and top secret national security launches using the Delta II, Delta IV and the Atlas V boosters.

NASA’s Magnetospheric Multiscale Mission (MMS) to study Earth’s magnetic reconnection is scheduled for launch on an Atlas V 421 booster on March 12 from Cape Canaveral. See my up close visit with MMS and NASA Administrator Charles Bolden at NASA Goddard Space Flight Center detailed in my story – here.

In March, June and September the GPS 2F-9, 2F-10 and 2F-11 navigation satellites will launch on Delta IV and Atlas V rockets from Cape Canaveral.

Two top secret NRO satellites are set to launch on a Delta IV and Atlas in April and August from Vandenberg.

An Air Force Orbital Test Vehicle (OTV) space plane may launch as soon as May atop an Atlas V from Cape Canaveral.

The MUOS-4 liftoff is set for August on another Atlas from the Cape.

The Morelos 3 communications satellite for the Mexican Ministry of Communications and Transportation is due to launch in October from the Cape.

In November, the Atlas V will be pressed into service for the first time to launch the Orbital Sciences Cygnus Orb-4 cargo vehicle to the International Space Station (ISS) as a replacement rocket for the Orbital Sciences Antares rocket which is grounded following its catastrophic Oct. 28 explosion on the Orb-3 mission from NASA Wallops.

Dramatic new photos and video of the daring and mostly successful attempt by Space X to land their Falcon 9 booster on an ocean-going “drone ship” were released this morning, Friday, Jan. 16, by SpaceX CEO and founder Elon Musk.

Musk posted the imagery online via his twitter account and they vividly show just how close his team came to achieving total success in history’s first attempt to land and recover a rocket on a tiny platform in the ocean.

Here’s the video: “Close, but no cigar. This time.”

The rocket landing and recovery attempt was a secondary objective of SpaceX, that immediately followed the spectacular nighttime blastoff of the Falcon 9 on Jan. 10 carrying the SpaceX Dragon cargo freighter spacecraft on a critical resupply mission for NASA bound for the space station.

The history making attempt at recovering the Falcon 9 first stage was a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a miniscule platform at sea using a rocket assisted descent by the first stage Merlin engines aided by steering fins.

The first stage rocket reached an altitude of over 100 miles after firing nine Merlins as planned for nearly three minutes. It had to be slowed from traveling at a velocity of about 2,900 mph (1300 m/s). The descent maneuver has been likened to someone balancing a rubber broomstick on their hand in the middle of a fierce wind storm.

The imagery shows the last moments of the descent as the rocket hits the edge of the drone ship at a 45 degree angle with its four landing legs extended and Merlin 1D engines firing.

Musk tweeted that the first stage Falcon 9 booster ran out of hydraulic fluid and thus hit the barge.

“Rocket hits hard at ~45 deg angle, smashing legs and engine section,” Musk explained today.

Lacking hydraulic fluid the boosters attached steering fins lost power just before impact.

“Before impact, fins lose power and go hardover. Engines fights to restore, but …,” Musk added.

This ultimately caused the Falcon 9 to crash land as the legs and engine section were smashed and destroyed as the fuel and booster burst into flames. The ship survived no problem.

“Residual fuel and oxygen combine.”

“Full RUD (rapid unscheduled disassembly) event. Ship is fine minor repairs. Exciting day!” said Musk.

“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted within hours after the launch and recovery attempt.

As I wrote on launch day here at Universe Today, despite making a ‘hard landing’ on the vessel dubbed the ‘autonomous spaceport drone ship,’ the 14 story tall Falcon 9 first stage did make it to the drone ship, positioned some 200 miles offshore of the Florida-Carolina coast, northeast of the launch site in the Atlantic Ocean. The rocket broke into pieces upon hitting the barge.

Whereas virtually every other news outlet quickly declared the landing attempt a “Failure” in the headline, my assessment as a scientist and journalist was the complete opposite!!

In my opinion the experiment was “a very good first step towards the bold company goal of recovery and re-usability in the future” as I wrote in my post launch report here at Universe Today.

Listen to my live radio interview with BBC 5LIVE conducted Saturday night (Jan. 11 UK time), discussing SpaceX’s first attempt to land and return their Falcon-9 booster.

“Is it safe? Was SpaceX brave or foolhardy? Why is this significant? Will SpaceX succeed in the future?” the BBC host asked me.

I replied; “It was a 99% success” and more …..

“Am super proud of my crew for making huge strides towards reusability on this mission. You guys rock!” Musk declared in a later tweet.

SpaceX achieved virtually all of their objectives in the daunting feat except for a soft landing on the drone ship.

This was a bold experiment involving re-lighting one of the first stage Merlin 1D engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.

Four attached hypersonic grid fins and a trio of Merlin propulsive burns succeeded in slowing the booster from hypersonic velocity to subsonic and guiding it to the ship.

The drone ship measures only 300 feet by 170 feet. That’s tiny compared to the Atlantic Ocean.

The first stage was planned to make the soft landing by extending four landing legs to a width of about 70 feet to achieve an upright landing on the platform with a accuracy of 30 feet (10 meters).

No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.

So they will learn and move forward to the next experimental landing, that could come as early as a few weeks on the launch of the DSCOVR mission in late January or early February.

“Upcoming flight already has 50% more hydraulic fluid, so should have plenty of margin for landing attempt next month.”

Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.

It remains to be seen whether his vision of reusing rockets can be made economical. Most of the space shuttle systems were reused, except for the huge external fuel tanks, but it was not a cheap proposition.

But we must try to cut rocket launch costs if we hope to achieve routine and affordable access to the high frontier and expand humanity’s reach to the stars.

The Falcon 9 launch itself was a flawless success, blasting off at 4:47 a.m. EST on Jan. 10 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The Dragon CRS-5 spacecraft was loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, the CATS science payload, student research investigations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person crew serving aboard the ISS.

It successfully rendezvoused at the station on Jan. 12 after a two day orbital chase, delivering the critical cargo required to keep the station stocked and humming with science.

Beagle 2: Found on Mars After An 11 Year Hunt

Credit & Coyright:

The final chapter in the saga of a wayward Mars lander was finally revealed today, as an international team released images showing the Beagle-2 lander’s final resting place on Mars.

Flashback to Christmas Day, 2003. While most folks gathered ‘round the tree and opened presents, the UK and European Space Agency awaited a gift from space.  The Beagle-2 Mars lander had been released from the European Space Agency’s Mars Express orbiter six days prior, and was coasting towards a perilous landing in Isidis Planitia and was set to phone home.

All was going according to plan, and then… silence.

It’s the worst part of any mission, waiting for a lander to call back and say that it’s safe and sound on the surface of another world. As the hours turned into days, anxious engineers used NASA’s Mars Odyssey spacecraft and the Lovell Telescope at Jodrell Bank to listen for the signal.

Beagle-2 was declared lost a few weeks later on February 6th, 2004.

But now, there’s a final twist to the tale to tell.

The UK Space Agency, working with ESA and NASA announced today that debris from the landing site had been identified and that indicates — contrary to suspicions — that Beagle-2 did indeed make it to the surface of the Red Planet intact. New images from the Mars Reconnaissance Orbiter released today suggest that not only did Beagle-2 land, but that its airbags did indeed deploy properly and that the dish-shaped 1-meter in diameter spacecraft partially unfolded pocket-watch style after it had bounced to a stop.

“We are very happy to learn that Beagle 2 touched down on Mars,” said ESA’s Director of Science and Robotic Exploration in a recent press release. “The dedication of the various teams in studying high-resolution images in order to find the lander is inspiring.”

So, what went wrong with Beagle-2?

At this point, no further speculation as to what caused the lander to fall silent has been forthcoming, but today’s revelation is sure to rewrite the final saga of Beagle-2.

“Not knowing what happened to Beagle-2 remained a nagging worry,” said ESA’s Mars Express project manager Rudolf Schmidt. “Understanding now that Beagle-2 made it all the way down to the surface is excellent news.”

Speculation swirled across the internet earlier this week as the UK Space Agency and ESA suggested that new information as to the fate of Beagle-2 was forthcoming, over 11 years after the incident. Back in 2004, it was suggested that Beagle-2 had encountered higher levels of dust in the Martian atmosphere than expected, and that this in turn resulted in a failure of the spacecraft’s parachutes. Presumably, the lander then failed to slow down sufficiently and crashed on the surface of Mars, the latest victim of the Great Galactic Ghoul who seems to love dining on human-built spacecraft bound for the Red Planet.

The loss of Beagle-2 wasn’t only a blow to the UK and ESA, but to its principal investigator Colin Pillinger as well. Pillinger was involved in the search for Beagle-2 in later years, and also played a part in the Rosetta mission to Comet 67P/Churyumov-Gerasimenko as well. Unfortunately, Pillinger passed away in May of last year from a brain hemorrhage. A portion of the western rim of Endeavour Crater currently being explored by Opportunity was named Pillinger Point in his honor.

Today’s announcement has triggered a wave of congratulations that the 11-year mystery has been solved. There have even been calls on Twitter and social media to rename the Beagle-2 site Pillinger Station.

“The history of of space exploration is marked by both success and failure,” Said Dr. David Parker, the Chief Executive of the UK Space Agency in a recent press release. “This finding makes the case that Beagle-2 was more of a success than we previously knew and undoubtedly an important step in Europe’s continuing exploration of Mars.”

Beagle-2 is about 2 metres across unfurled, and came to rest within 5 kilometres of its target location.

There have been false announcements of the discovery of Beagle-2 before. Back in late 2005, a claim was made that the lander had been spotted by Mars Global Surveyor, though later searches came to naught.

“I can imagine the sense of closure that the Beagle-2 team must feel,” Said JPL’s MRO project scientist Richard Zurek in a recent press release. “MRO has helped find safe landing sites on Mars for the Curiosity and Phoenix missions and has searched for missing craft to learn what may have gone wrong. It’s an extremely difficult task.”

MRO entered orbit in March 2006 and carries a 0.5 metre in diameter HiRISE camera capable of resolving objects just 0.3 metres across on the surface of Mars.  The European Space Agency’s Mars Express orbiter that carried Beagle 2 is also still in operation, along with NASA’s aging Mars Odyssey spacecraft. These were joined in orbit by MAVEN and India’s Mars Orbiter just last year.

Of course, getting to Mars is tough, and landing is even harder. Mars has just enough atmosphere that you have to deal with it, but it’s so tenuous – 0.6% the surface pressure of Earth’s atmosphere at sea level – That it doesn’t provide a whole lot of usable drag.

To date, only NASA had successfully landed on Mars, and done it seven times – only the Mars Polar Lander failed back in 1999. The Russians fared much worse, with their most successful lander being Mars 3, which sent back only one blurry image before falling silent.

ESA and the Russian Federal Space Agency hope to amend that with the launch of the ExoMars mission next year, slated to land on Mars in 2018.

I remember waiting with millions of other space fans for word back from Beagle 2 on Christmas Day 2003. Think back to what your internet connection was like over 11 years ago, in an era before smart phones, Twitter and Facebook. We’d just come off of the spectacular 2003 Mars opposition season, which provided the orbital geometry ideal for launching a mission to the Red Planet. This window only comes around once every 26 months.

Though Beagle 2 was a stationary lander akin to the Viking and Mars Phoenix missions, it had a robotic arm and a clever battery of experiments, including ones designed to search for life. The signal it was supposed to use to call home was designed by the UK pop rock band Blur, a jingle that never came.

Alas, we’ll have to wait to see what the alien plains around Isidis Planitia actually look like, just 13 degrees north of the Martian equator. But hey, a lingering mystery of the modern age of planetary exploration was solved this week.

Still, we’re now left with a new dilemma. Does this mean we’ll have to write a sequel to our science fiction short story The Hunt for Beagle?

First SLS Engine Blazes to Life in Mississippi Test Firing Igniting NASA’s Path to Deep Space

NASA’s goal of sending astronauts to deep space took a major step forward when the first engine of the type destined to power the mighty Space Launch System (SLS) exploration rocket blazed to life during a successful test firing at the agency’s Stennis Space Center near Bay St. Louis, Mississippi.

The milestone hot fire test conducted on Jan. 9, involved igniting a shuttle-era RS-25 space shuttle main engine for 500 seconds on the A-1 test stand at Stennis.

A quartet of RS-25s, formerly used to power the space shuttle orbiters, will now power the core stage of the SLS which will be the most powerful rocket the world has ever seen.

“The RS-25 is the most efficient engine of its type in the world,” said Steve Wofford, manager of the SLS Liquid Engines Office at NASA’s Marshall Space Flight Center, in Huntsville, Alabama, where the SLS Program is managed. “It’s got a remarkable history of success and a great experience base that make it a great choice for NASA’s next era of exploration.”

The SLS is NASA’s mammoth heavy lift rocket now under development. It is intended to launch the Orion deep space crew capsule and propel astronauts aboard to destinations far beyond Earth and farther into space than ever before possible – beyond the Moon, to Asteroids and Mars.

The over eight minute RS-25 engine test firing provided NASA engineers with critical data on the engine controller unit, which is the “brain” of the engine providing communications between the engine and the vehice, and inlet pressure conditions.

“The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status. The new controller will use updated hardware and software configured to operate with the new SLS avionics architecture,” according to NASA.

This also marked the first test of a shuttle-era RS-25 since the conclusion of space shuttle main engine testing in 2009.

For the SLS, the RS-25 will be configured and operated differently from their use when attached as a trio to the base of the orbiters during NASA’s four decade long Space Shuttle era that ended with the STS-135 mission in July 2011.

“We’ve made modifications to the RS-25 to meet SLS specifications and will analyze and test a variety of conditions during the hot fire series,” said Wofford

“The engines for SLS will encounter colder liquid oxygen temperatures than shuttle; greater inlet pressure due to the taller core stage liquid oxygen tank and higher vehicle acceleration; and more nozzle heating due to the four-engine configuration and their position in-plane with the SLS booster exhaust nozzles.”

Watch this video of the RS-25 engine test:

The SLS core stage stores the cryogenic liquid hydrogen and liquid oxygen that fuel the RS-25 first stage engines.

“This first hot-fire test of the RS-25 engine represents a significant effort on behalf of Stennis Space Center’s A-1 test team,” said Ronald Rigney, RS-25 project manager at Stennis.

“Our technicians and engineers have been working diligently to design, modify and activate an extremely complex and capable facility in support of RS-25 engine testing.”

The Jan. 9 engine test was just the first of an extensive series planned. After an upgrade to the high pressure cooling system, an initial series of eight development tests will begin in April 2015 totaling 3,500 seconds of firing time.

The SLS core stage is being built at NASA’s Michoud Assembly Facility in New Orleans.

On Sept. 12, 2014, NASA Administrator Charles Bolden officially unveiled the world’s largest welder at Michoud, that will be used to construct the core stage, as I reported earlier during my on-site visit.

“This rocket is a game changer in terms of deep space exploration and will launch NASA astronauts to investigate asteroids and explore the surface of Mars while opening new possibilities for science missions, as well,” said NASA Administrator Charles Bolden during the ribbon-cutting ceremony at Michoud.

The core stage towers over 212 feet (64.6 meters) tall and sports a diameter of 27.6 feet (8.4 m).

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

Orion’s inaugural mission dubbed Exploration Flight Test-1 (EFT) was successfully launched on a flawless flight on Dec. 5, 2014 atop a United Launch Alliance Delta IV Heavy rocket Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.
