On Friday night/early Saturday May 23-24 skywatchers across the U.S. and southern Canada may witness the birth of a brand new meteor shower.  If predictions hold true, Earth will pass through multiple tendrils of dust and pebbly bits left behind by comet 209P/LINEAR, firing up a celestial display on par with the strongest showers of the year. Or better.

Earlier predictions called for a zenithal hourly rate or ZHR of 1,000 per hour, pushing this shower into the ‘storm’ category. ZHR is an idealized number based on the shower radiant located at the zenith under ideal skies. The actual number is lower depending on how far the radiant is removed from the zenith and how much light pollution or moonlight is present. Meteor expert Peter Jenniskens of the SETI Institute and Finland’s Esko Lyytinen first saw the possibility of a comet-spawned meteor storm and presented their results in Jenniskens’ 2006 book Meteor Showers and Their Parent Comets.

Quanzhi Ye and Paul Wiegert  (University of Western Ontario) predict a weaker shower because of a decline in the comet’s dust production rate based on observations made during its last return in 2009. They estimate a rate of ~200 per hour.

On the bright side, their simulations show that the comet sheds larger particles than usual, which could mean a shower rich in fireballs. Other researchers predict rates between 200 and 40o per hour. At the very least, the Camelopardalids – the constellation from which the meteors will appear to originate – promise to rival the Perseids and Geminids, the year’s richest showers. Motivation for setting the alarm clock if there ever was.

Comet 209P/LINEARdiscovered in Feb. 2004 by the automated Lincoln Laboratory Near-Earth Asteroid Research (LINEAR) sky survey, orbits the sun every 5.04 years with an aphelion (most distant point from the sun) near Jupiter. In 2012, during a relatively close pass of that planet, Jupiter perturbed its orbit, bringing it to within 280,000 miles (450,000 km) of Earth’s orbit.

That set up a remarkably close encounter with our planet on May 29 when 209P will cruise just 5 million miles (8 million km) from Earth to become the  9th closest comet ever observed. Multiple debris trails shed by the comet as long ago as the 18th century will intersect our planet’s path 5 days earlier, providing the material for the upcoming meteor shower/storm.

Shining meekly around magnitude +17 at the moment, 209P/LINEAR could brighten to magnitude +11 as it speeds from the Big Dipper south to Hydra during the latter half of May. Closer to the BIG night, we’ll provide helpful maps for you to track it down in your telescope. Cool to think that both the shower and its parent comet will be on display at the same time.

The shower’s expected to last only a few hours from about 12:40-3:50 a.m. CDT with the best viewing locations in the U.S. and southern half of Canada. This is where the radiant will be up in a dark sky at peak activity. A thick crescent moon rises around 3-3:30 a.m. but shouldn’t pose a glare problem.

Meteors from 209P/LINEAR are expected to be bright and slow with speeds around 40,000 mph compared to an average of 130,000 mph for the Perseids. Most shower meteoroids are minute specks of rock, but the Camelopardalids contain a significant number of particles larger than 1mm – big enough to spark  fireballs.

The farther north you live in the shaded area on the map, the higher the radiant stands in the northern sky and the more meteors you’re likely to see. Skywatchers living in the Deep South will see fewer shooting stars, but a greater proportion will be earthgrazers, those special meteors that skim the upper atmosphere and flare for an unusually long time before fading out.

To see the shower at its best, find a dark place with an open view to the north. Plan your viewing between 12:30 and 4 a.m. CDT (May 24), keeping the 2 a.m. forecast peak in mind. Maximum activity occurs around 3 a.m. Eastern, 1 a.m. Mountain and midnight Pacific  time.

No one’s really certain how many meteors will show, but I encourage you to make the effort to see what could be a spectacular show.

Curiosity Reaches Out to Scrutinize Next Martian Drill Target at Mount Remarkable

To Drill or not to Drill?

That’s the momentous question posed by the international team of scientists and engineers who commanded NASA’s SUV sized Curiosity rover to reach out with her high tech robotic arm this weekend (Apr 25-27) and gather critical science measurements for high powered scrutiny of an outcrop on a Martian butte named Mount Remarkable.

See our multisol, composite photo mosaic – above – illustrating Curiosity’s arm in action pressing down her X-ray spectrometer on Saturday, April 26, Sol 612, at an alien rock on Mount Remarkable at the current stopping point at “The Kimberley Waypoint” along the epic trek to towering Mount Sharp.

Via a combination of laser shots, images, brushings and spectrometry the team is pondering new data streaming back daily across hundreds of millions of kilometers of interplanetary space to Earth to determine whether to bore into a sandstone slab being evaluated as the target for the missions third drilling campaign.

The team deployed the arm this weekend onto a rock target called “Windjana,” after a gorge in Western Australia.

After confirming that the 1 ton robot was in a stable position, the team commanded study observations on Saturday, Sol 612, using the APXS spectrometer and MAHLI camera on the terminus of the arm’s turret.

“The observation will document its chemical composition and morphology before drilling,” says science team member Ken Herkenoff in a mission update.

She also brushed off the potential ‘Windjana’ drill target with the wire-bristle Dust Removal Tool (DRT) to clear away obscuring Red Planet dirt and dust hindering the data collections.

The rover is also conducting continuing remote sensing observations with the ChemCam, Mastcam and Navcam cameras mounted on the Mast.

Today, April 27, Sol 613, “MAHLI will take another selfie of the rover” according to Herkenhoff.

In early April, the six wheeled rover pulled into a scientifically enticing science destination known as “The Kimberley Waypoint” in hopes of carrying out the next drilling operation into alien Martian terrain in search of further clues about ancient Martian environments that may have been favorable for life.

“We are officially in ‘The Kimberley’ now,” Curiosity Principal Investigator John Grotzinger, of the California Institute of Technology, Pasadena, told me at that time.

Since arriving in the Kimberley region, Curiosity’s earth bound handlers have been maneuvering the 1 ton robot around to thoroughly survey destination “Kimberley” in choosing the best drill site.

Why was Kimberley chosen as a science destination ?

“The Kimberley” has interesting, complex stratigraphy,” Grotzinger told me.

If Windjana meets the required criteria, Curiosity will bore into the sandstone rock, and then pulverize and filter it prior to delivery to the two onboard miniaturized chemistry labs – SAM and CheMin.

Windjana would be the first sandstone drill target, if selected. The first two drill locations at ‘John Klein’ and ‘Cumberland’ inside Yellowknife Bay were mudstone.

Curiosity departed the ancient lakebed at the Yellowknife Bay region in July 2013 where she discovered a habitable zone with the key chemical elements and a chemical energy source that could have supported microbial life billions of years ago – and thereby accomplished the primary goal of the mission.

“We want to learn more about the wet process that turned sand deposits into sandstone here,” said Grotzinger, in a NASA statement.

“What was the composition of the fluids that bound the grains together? That aqueous chemistry is part of the habitability story we’re investigating.”

“Understanding why some sandstones in the area are harder than others also could help explain major shapes of the landscape where Curiosity is working inside Gale Crater. Erosion-resistant sandstone forms a capping layer of mesas and buttes. It could even hold hints about why Gale Crater has a large layered mountain, Mount Sharp, at its center,” NASA elaborated in the statement.

To date, Curiosity’s odometer totals 3.8 miles (6.1 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 143,000 images.

The sedimentary foothills of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the 1 ton robots ultimate destination inside Gale Crater because it holds caches of water altered minerals. Such minerals could possibly indicate locations that sustained potential Martian life forms, past or present, if they ever existed.

Curiosity has some 4 kilometers to go to reach the base of Mount Sharp sometime later this year.

SpaceX CEO Elon Musk Sues Government to Break US Air Force’s National Security Launch Monopoly

SpaceX CEO Elon Musk announces lawsuit protesting Air Force launch contracts while speaking at the National Press Club in Washington, DC on April 25, 2014

SpaceX CEO Elon Musk announces lawsuit protesting Air Force launch contracts while speaking at the National Press Club in Washington, DC on April 25, 2014
Story updated[/caption]

Elon Musk, CEO and founder of the upstart commercial launch venture SpaceX, announced at a press conference today, Friday, April 25, that SpaceX is filing suit against the Federal Government to protest and break the US Air Force’s awarding of lucrative launch contracts for high priority national security satellites to a sole rocket provider – United Launch Alliance (ULA) – on a non competitive basis.

The gloves are officially off in the intensely mounting duel over multibillion dollar Air Force military launch contracts between SpaceX and ULA.

“The official protest document will be available Monday, April 28th at www.freedomtolaunch.com and will be filed with the United States Court of Federal Claims in Washington, D.C.,” said SpaceX in an official statement.

Musk said the Air Force launch contract with ULA amounted to a continuing monopoly, was unfair by blocking SpaceX from competing for launches of surveillance satellites and would cost taxpayers billions of extra dollars in coming years.

“What we feel is that this is not right – that the national security launches should be put up for competition and they should not be awarded on a sole source, uncompeted basis,” said Musk at the briefing called on short notice and held at the National Press Club in Washington, DC.

The latest Air Force launch contract dated to December 2013 guarantees the “block buy” purchase of 36 rocket cores from ULA for national security launches for the DOD, NRO and other government agencies, at a significantly reduced cost compared to earlier contracts.

A further 14 cores were to be awarded on a competitive basis, including bids from SpaceX and others who seek to gain Air Force certification. Several of those launch awards have now been deferred indefinitely.

ULA is a joint venture between aerospace giants Boeing and Lockheed Martin, formed in 2006, that has launched over 80 satellites to orbit and beyond including many NASA science and mission probes like Orion EFT-1, Curiosity, MAVEN, TDRS and more.

It manufactures the Delta IV and Atlas V unmanned, expendable rocket families that are currently the only boosters certified to launch the high value military payloads at issue in the lawsuit announced on Friday by Musk.

The newest versions of the Delta and Atlas rockets – known as EELV’s (Evolved Expendable Launch Vehicles) have had nearly flawless records of success since being introduced some dozen years ago by the companies individually, before the ULA merger.

Musk wants his company’s newer and he says much cheaper Falcon 9 and Falcon Heavy rockets to be certified by the Air Force and included in the competition for launch contracts.

To date the Falcon 9 has launched only 9 times. Only four of those were in the new and more powerful configuration needed by the Air Force.

Musk is not asking that the launches be awarded outright to SpaceX. But he does want the Air Force contract cancelled and re-competed.

“We’re just protesting and saying that the launches should be competed,” Musk said.

“If we compete and lose that’s fine. But why were they not even competed? That just doesn’t make sense.”

“So far we are most of the way through the certification process. And so far there have been zero changes to the rocket. Mostly it’s just been a paperwork exercise.”

“Since this is a large multiyear contract, why not wait a few months for the certification process to complete. And then do the competition. That seems very reasonable to me.”

Musk said it costs four times more to launch ULA’s Delta or Atlas rocket vs. a SpaceX Falcon rocket.

“The ULA rockets are basically four times more expensive than ours. So this contract is costing US taxpayers billions of dollars for no reason.”

“Each launch by ULA costs American taxpayers roughly $400 million per launch. They are insanely expensive. I don’t know why they are so expensive.”

The Falcon 9 lists for about $60 Million per launch, but rises to about $100 million after the certification costs are included, Musk explained.

“So yes the certification does make our Falcon 9 rocket more expensive. But not 400% more expensive.”

“Our rockets are 21st century design,” said Musk to obtain the most efficiency. He said ULA’s designs date back to the 90s and earlier with heritage hardware.

To date the Falcon 9 has already been used three times under a $1.6 Billion contract with NASA to launch the private SpaceX Dragon resupply vessel to the International Space Station (ISS) – most recently a week ago during the April 18 blastoff of the SpaceX CRS-3 mission from Cape Canaveral.

It is also being used to launch highly expensive communications satellites like SES-8 and Thaicom-6 for private companies to geostationary orbits.

“It just seems odd that if our vehicle is good enough for NASA and supporting a $100 billion space station, and it’s good enough for launching NASA science satellites, for launching complex commercial geostationary satellites, then there’s no reasonable basis for it not being capable of launching something quite simple like a GPS satellite,” said Musk.

“Our only option is to file a protest.”

Furthermore as I wrote here in a prior article, US National Security launches are now potentially at risk due to the ongoing crisis between Russian, Ukraine and Crimea because the RD-180 first stage engines powering the Atlas V are designed and manufactured in Russia by NPO Energomash, majority owned by the Russian Federation.

“The head of the Russian space sector, Dmitry Rogozin, was sanctioned by the White House in March 2014 in the wake of Russia’s aggression in Ukraine,” says SpaceX.

The RD-180 engine supply could be cut off in a worst case scenario if economic sanctions against Russia are increased by the Western allies.

ULA has a two year contingency supply of the RD-180’s and blueprints to begin production, if needed.

However in the event of a cutoff, it would take at least three to five years to start and certify RD-180 engine production somewhere in the US, a ULA spokesperson told me recently at Cape Canaveral.

This possibly leaves a 1 to 3 year gap with no Atlas V 1st stage engine supply.

The Delta IV rockets and engines by contrast are manufactured in the US.

“In light of international events, this seems like the wrong time to send hundreds of millions of dollars to the Kremlin,” said Musk.

“Yet, this is what the Air Force’s arrangement with ULA does, despite the fact that there are domestic alternatives available that do not rely on components from countries that pose a national security risk.”

Stay tuned here for Ken’s continuing SpaceX, Orbital Sciences, commercial space, Orion, Chang’e-3, LADEE, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Imagine What Could Be Done With a “Penny4NASA”

NASA's % of the U.S. budget over the years

If you’re reading this then you’re probably a big fan of space exploration. And while on one hand you could say that we are now living in a “golden age” of exploration, what with the ongoing missions there are around the Solar System and the new discoveries being made on an almost weekly basis about our Universe, on the other hand it seems like we are getting more and more “grounded” as human explorers, with still years to go before the first footprints are made on Mars, an ever-growing span since we last walked on the Moon, and steadily-shrinking or stagnant budgets that can’t support all the missions that DO exist — and sometimes cancel them altogether.

“We have discovered amazing places. But imagine what’s hiding where we haven’t even looked?”


In order for missions to ever get off the ground, they need to be funded. Right now NASA — still arguably the leader in space exploration among world agencies — receives a little over 0.4 percent of every U.S. tax dollar. Less than half a penny. That’s what NASA explores the Solar System with, what makes our knowledge of the Universe — from the farthest visible reaches right down to our own planet Earth — even possible. What if NASA were to receive a full one percent? A whole penny from every dollar? That’d still be only a quarter of what NASA worked with to put men on the Moon in 1969, but it’d be more than double what it gets now.

A penny for NASA… this is the goal of Penny4NASA.org, an outreach group that strives to increase the funding — if just by a little — of the world’s most accomplished, inspirational, and powerful space exploration administration. (Before… you know, it isn’t.)

The video above was created for Penny4NASA by artist and animator Brad Goodspeed, and reminds us of what NASA has achieved in its 50-year history, of what its goals are (or at least should be) and, unfortunately, why many of them have remained unattained. NASA needs support — our support — or else its candles will stay unlit and our windows and doors to the Universe will slowly but surely close.

How can you help? Well for one thing, stay excited about space and science (and get others excited too!) Interest is the key to making sure people don’t lose sight of what’s happening in the field; you might be surprised to hear the misinformation that’s been passed around. (No, NASA isn’t “dead.”) And let your policy-makers know that space exploration and the investment in technology and innovation that goes along with it is important to you — the Planetary Society has a convenient page where you can find links to write to your state representative here. And finally you can support groups like Penny4NASA, made up of enthusiastic young professionals who want to see our nation’s past successes in space exploration continued into their future.

“America is fading right now. Nobody’s dreaming about tomorrow anymore. NASA knows how to dream about tomorrow — if the funding can accommodate it, if the funding can empower it.”

The Curiosity rover has captured the first images of asteroids even taken by a Human probe from the alien surface of the Red Planet during night sky imaging.

And it’s not just one asteroid, but two asteroids caught in the same night time pointing on the Red Planet. Namely, asteroids Ceres and Vesta.

The stupendous image – seen above – was snapped by Curiosity’s high resolution Mastcam camera earlier this week on Sunday, April 20, 2014, Sol 606, whilst she was scanning about during daylight for her next drilling target at “The Kimberley” waypoint she pulled into at the start of this month.

Ceres and Vesta appear as streaks since the Mastcam image was taken as a 12 second time exposure.

“This imaging was part of an experiment checking the opacity of the atmosphere at night in Curiosity’s location on Mars, where water-ice clouds and hazes develop during this season,” said camera team member Mark Lemmon of Texas A&M University, College Station, in a statement.

“The two Martian moons were the main targets that night, but we chose a time when one of the moons was near Ceres and Vesta in the sky.”

View our “Kimberley” region photo mosiacs below to see exactly from where the six wheeled robot took the asteroid image shown above, while driving around the base of “Mount Remarkable”.

And those two asteroids are extra special because not only are they the two most massive objects in the Main asteroid belt between Mars and Jupiter, but they are also the destinations of another superlative NASA unmanned mission – Dawn.

The exotic Dawn probe, propelled by a stream of ions, orbited Vesta for a year in 2011 and is now approaching Ceres for an exciting orbital mission in 2015.

Ceres, the largest asteroid, is about 590 miles (950 kilometers) in diameter. Vesta is the third-largest object in the main belt and measures about 350 miles (563 kilometers) wide.

And as if Curiosity’s mouthwatering and heavenly double asteroid gaze wasn’t already spectacular enough, the tinier of Mars’ moons, Deimos, was also caught in that same image.

A trio of star trails is also seen, again due to the 12 second time exposure time.

Furthermore, Mars largest moon Phobos as well as massive planets Jupiter and Saturn were also visible that same Martian evening, albeit in a different pointing.

These celestial objects are all combined in the composite image above.

“The background is detector noise, limiting what we can see to magnitude 6 or 7, much like normal human eyesight. The two asteroids and three stars would be visible to someone of normal eyesight standing on Mars. Specks are effects of cosmic rays striking the camera’s light detector,” says NASA.

Curiosity’s makers back on Earth are nowhere to be seen. But check out the Curiosity’s earlier photo below of the Earth and Moon from my prior article – here.

To date, Curiosity’s odometer totals 3.8 miles (6.1 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 143,000 images.

The sedimentary foothills of Mount Sharp, which reaches 3.4 miles (5.5 km) into the Martian sky, is the 1 ton robots ultimate destination inside Gale Crater because it holds caches of water altered minerals. Such minerals could possibly indicate locations that sustained potential Martian life forms, past or present, if they ever existed.

LADEE Sees Zodiacal Light before Crashing into Moon, but Apollo Mystery Remains

NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) literally ‘saw the light’ just days before crashing into the lunar farside last Thursday April 17. Skimming just a few kilometers above the moon’s surface, mission controllers took advantage of this unique low angle to gaze out over the moon’s horizon in complete darkness much like the Apollo astronauts did from lunar orbit more than 40 years ago.

With the glow of Earth well-hidden, any dust in the moon’s scant atmosphere around the time of orbital sunrise should become visible. Scientists also expected to see  the softly luminous glow of the zodiacal light, an extensive cloud of comet and asteroid dust concentrated in the flat plane of the solar system. The zodiacal light gets its name from the zodiac, that familiar band of constellations the planets pass through as they orbit the sun. Back on Earth, the zodiacal light looks like a big thumb of light standing up from the western horizon a couple hours after sunset in spring and before sunrise in fall.

So what did LADEE see? As you watch the animation above, comprised of images taken from darkness until sunrise, you’ll see a yellow haze on the horizon that expands into large diffuse glow tilted slightly to the right. This is the zodiacal light along with a smaller measure of light coming from sun’s outer atmosphere or corona.  Together they’re referred to as CZL or ‘coronal and zodiacal light’. At the very end, the sun peaks over the lunar horizon.

This is a sketch of the lunar sunrise seen from orbit by Apollo 17 astronaut Eugene Cernan. On the right, the sketch is highlighted to show the sources of the scattered light: red indicates Coronal and Zodiacal Glow, blue is the Lunar Horizon Glow, perhaps caused by exospheric dust, and green indicates possible "streamers" of light (crepuscular rays) formed by shadowing and scattered light.

What appears to be missing from the pictures are the mysterious rays seen by some of the Apollo astronauts. The rays, neatly sketched by astronaut Eugene Cernan of Apollo 17, look a lot like those beams of light and shadow streaming though holes in clouds called crepuscular rays.

Only thing is, Earth’s atmosphere is thick enough for cloud beams. The dust in the moon’s atmosphere appears much too thin to cause the same phenomenon. And yet the astronauts saw rays as if sunlight streamed between mountain peaks and scattered off the dust just like home.

It’s believed that dust gets lofted into the spare lunar atmosphere via electricity. Ultraviolet light from the sun knocks electrons from atoms in moon dust, giving them a positive charge. Since like charges repel, bits of dust push away from one another and move in the direction of least resistance: up. The smaller the dust particle, the higher it rises until dropping back down to the surface. Perhaps these “fountains” of lunar dust illuminated by the sun are what the astronauts recorded.

Unlike Cernan, LADEE saw only the expected coronal and zodiacal light but no rays. Scientists plan to look more closely at several sequences of images made of lunar sunrise in hopes of finding them.

UPDATE: Spacewalkers Zip Through Tasks To Fix Broken Computer

UPDATE, 11:42 a.m. EDT: Rick Mastracchio and Steve Swanson finished their spacewalk in just 1 hour and 36 minutes, nearly an hour faster than what NASA budgeted for. Early tests show the replacement computer is working well, providing backup once again for the robotics, solar arrays and other systems on station.

Can two astronauts fix a broken computer quickly on the International Space Station, preventing possible problems with the solar arrays and robotics? Watch live (above) to find out.

The NASA spacewalk involving Rick Mastracchio and Steve Swanson is scheduled to start today (April 23) at 9:20 a.m. EDT (1:20 p.m. UTC), with coverage starting around 8:30 a.m. EDT (12:30 p.m. UTC). The spacewalk is scheduled to last 2.5 hours. Bear in mind that the times could change as circumstances arise.

The computer, also called a multiplexer/demultiplexer (MDM), failed for unknown reasons a couple of weeks ago. While the primary computer is working perfectly and the crew is in no danger, things get more risky if the primary computer also breaks. That’s why NASA worked to get the spacewalkers outside as quickly as possible. You can see a full briefing of the rationale here.

As a note, all non-urgent spacewalks have been suspended because NASA is still working on addressing the recommendations given after a life-threatening water leak took place in a NASA spacesuit last summer. Urgent spacewalks can still go ahead because the agency has implemented safety measures such as snorkels and helmet absorption pads in case of another leak.

That said, in the months since NASA has traced the problem to contamination in a filter in the fan pump separator. After replacing the separator, the leaky spacesuit was used during two contingency spacewalks in December with no water problems at all.

Remembering John Houbolt: the Man Who Gave Us Lunar Orbit Rendezvous

The space community lost a colossus of the of the Apollo era last week, when John Houbolt passed away last Tuesday just five days after his 95th birthday.

Perhaps the name isn’t as familiar to many as Armstrong or Von Braun, but John Houbolt was a pivotal figure in getting us to the Moon.

Born in Altoona, Iowa on April 10th, 1919, Houbolt spent most of his youth in Joliet, Illinois. He earned a Masters degree in Civil Engineering from the University of Illinois at Urbana-Champaign in 1942 and a PhD in Technical Sciences from ETH Zurich in Switzerland in 1957. But before that, he would become a member of the National Advisory Committee for Aeronautics (NACA) in 1942, an organization that would later become the National Aeronautics and Space Administration or NASA in 1958.

It was 1961 when Houbolt made what would be his most enduring mark on the space program. He was working as an engineer at the Langley Research Center, at a time when NASA and the United States seriously needed a win in the space race. The U.S.S.R. had enjoyed a long string of firsts, including first satellite in orbit (Sputnik 1, October 1957), first spacecraft to photograph the lunar farside (Luna 3 in October 1959) and first human in space with the launch of Yuri Gagarin aboard Vostok 1 in April 1961. A young President Kennedy would make his now famous “We choose to go to the Moon…” speech at Rice University later the next year in late 1962. Keep in mind, in U.S. astronaut John Glenn had just made his first orbital flight months before Kennedy’s speech, and total accumulated human time in space could be measured in mere hours. Unmanned Ranger spacecraft were having a tough time even getting off of the pad, and managing to crash a space probe into the Moon was considered to be a “success”. The task of sending humans “by the end of this decade” was a daunting one indeed…

NASA would soon have a mandate to sent humans to the Moon: but how could they pull it off?

Early ideas for manned lunar missions envisioned a single gigantic rocket that would head to the Moon and land, Buck Rodgers style, “fins first.” Such a rocket would have to be enormous, and carry the fuel to escape Earth’s gravity well, land and launch from the Moon, and return to Earth.

A second approach, known as Earth-orbit rendezvous, would see several launches assemble a mission in low Earth orbit and then head to the Moon. Curiously, though this was an early idea, it was never used in Apollo, though it was briefly resurrected during the now defunct Constellation Program.

But it was a third option that intrigued Houbolt, known as Lunar Orbit Rendezvous. LOR had been proposed by rocket pioneers Yuri Kondratyuk and Hermann Oberth in 1923, but had never been seriously considered. It called for astronauts to depart the Earth in a large rocket, and instead, use a small lander designed only to land and launch from the Moon while the spacecraft for Earth return orbited overhead.

Houbolt became a staunch advocate for the idea, and spent over a year convincing NASA officials. In one famous letter to NASA associate administrator Robert Seamans, Houbolt was known to have remarked “Do we want to go to the Moon or not?”

It’s interesting to note that it was probably only in a young organization like the NASA of the early 1960s that, in Houbolt’s own words, a “voice in in the wilderness” could be heard. Had NASA become a military run organization — as many advocated for in the 1950s — a rigid chain of command could have meant that such brash ideas as Houbolt’s would have never seen the light of day. Thank scientists such as James Van Allen for promoting the idea of a civilian space program that we take for granted today.

Even then, selling LOR wasn’t easy. The idea looked preposterous: astronauts would have to learn how to undock and dock while orbiting a distant world, with no chance of rescue. There was no second chance, no backup option. Early plans called for an EVA for astronauts to enter the Lunar Module prior to descent which were later scrapped in favor of extracting it from atop the third stage and boarding internally before reaching the Moon.

Once Houbolt had sold key visionaries such as Wernher von Braun on the idea in late 1962, LOR became the way we would go to the Moon. And although Houbolt’s estimations of the mass required for the Lunar Module were off by a factor of three, the story is now the stuff of early Apollo era legend. You can see Houbolt (played by Reed Birney) and the tale of the LM and LOR in the  From Earth to the Moon episode 5 entitled “Spider”.

Houbolt was awarded NASA’s medal for Exceptional Scientific Achievement in 1963, and he was in Mission Control When Apollo 11 touched down in the Sea of Tranquility.

He passed away in a Scarborough, Maine nursing home last Tuesday, and joins other unsung visionaries of the early space program such as Mary Sherman Morgan. It’s sad to think that we may soon live in a world where those who not only walked on the Moon, but those who also sent us and knew how to get there, are no longer with us.

Thanks, John… you gave us the Moon.

Our Guide to the Bizarre April 29th Solar Eclipse

Will anyone see next week’s solar eclipse? On April 29th, an annular solar eclipse occurs over a small D-shaped 500 kilometre wide region of Antarctica. This will be the second eclipse for 2014 — the first was the April 15th total lunar eclipse — and the first solar eclipse of the year, marking the end of the first eclipse season. 2014 has the minimum number of eclipses possible in one year, with four: two partial solars and two total lunars. This month’s solar eclipse is also a rarity in that it’s a non-central eclipse with one limit. That is, the center of the Moon’s shadow — known as the antumbra during an annular eclipse — will juuuust miss the Earth and instead pass scant kilometres above the Antarctic continent.

A solar eclipse is termed “non-central with one limit” when the center of the Moon’s umbra or antumbra just misses the Earth and grazes it on one edge. Jean Meeus and Fred Espenak note that out of 3,956 annular eclipses occurring from 2000 BCE to 3000 AD, only 68 (1.7%) are of the non-central variety. An annular eclipse occurs when the Moon is too distant to cover the disk of the Sun, resulting in a bright “annulus” or “ring-of-fire” eclipse. A fine example of just such an eclipse occurred over Australia last year on May 10th, 2013. An annular eclipse crossed the United States on May 10th, 1994 and will next be seen from the continental U.S. on October 14th 2023. But of course, we’ll see an end the “total solar eclipse drought” long before that, when a total solar eclipse crosses the U.S. on August 21st, 2017!

The “centrality” of a solar eclipse or how close a solar eclipse comes to crossing the central disk of the Earth is defined as its “gamma,” with 0 being a central eclipse, and 1 as the center of the Moon’s shadow passing 1 Earth radii away from central. All exclusively partial eclipses have a gamma greater than 1. The April 29th eclipse is also unique in that its gamma is very nearly 1.000… in fact, combing the 5,000 year catalog of eclipses reveals that no solar eclipse from a period of 2000 B.C. to 3000 A.D. comes closer to this value. The solar eclipses of October 3rd, 2043 and March 18th, 1950 are, however very similar in their geometry. Guy Ottewell notes in his 2014 Astronomical Calendar that the eclipses of August 29th, 1486 and January 8th, 2141 also come close to a gamma of 1.000. On the other end of the scale, the solar eclipse of July 11th 1991 had a gamma of nearly zero. This eclipse is part of saros series 148 and is member 21 of 75. This series began in 1653 and plays out until 2987 AD. This saros will also produce one more annular eclipse on May 9th 2032 before transitioning to a hybrid and then producing its first total solar eclipse on May 31st, 2068. But enough eclipse-geekery. Do not despair, as several southern Indian Ocean islands and all of Australia will still witness a fine partial solar eclipse from this event. Antarctica has the best circumstances as the Sun brushes the horizon, but again, the tiny sliver of “annularity” touches down over an uninhabited area between the Dumont d’Urville and Concordia  stations currently occupied by France… and it just misses both! And remember, its astronomical fall headed towards winter “down under,” another strike against anyone witnessing it from the polar continent. A scattering of islands in the southern Indian Ocean will see a 55% eclipsed Sun. Circumstances for Australia are slightly better, with Perth seeing a 55% eclipsed Sun and Sydney seeing a 50% partial eclipse.

Darwin,  Bali Indonesia and surrounding islands will see the Moon just nick the Sun and take a less than 20% “bite” out of it. Observers in Sydney and eastern Australia also take note: the eclipse occurs low to the horizon to the west at sunset, and will offer photographers the opportunity to grab the eclipse with foreground objects. Viewing a partial solar eclipse requires proper eye protection throughout all phases. The safest method to view a partial solar eclipse is via projection, and this can be done using a telescope (note that Schmidt-Cassegrain scopes are bad choice for this method, as they can heat up quickly!) or nothing more sophisticated than a spaghetti strainer to create hundreds of little “pinhole projectors.”

And although no human eyes may witness the annular portion of this eclipse, some orbiting automated ones just might. We ran some simulations using updated elements, and the European Space Agency’s Sun observing Proba-2 and the joint NASA/JAXA Hinode mission might just “thread the keyhole” and will witness a brief central eclipse for a few seconds on April 29th: And though there’ll be few webcasts of this remote eclipse, the ever-dependable Slooh is expected to carry the eclipse on April 29th. Planning an ad hoc broadcast of the eclipse? Let us know! As the eclipse draws near, we’ll be looking at the prospects for ISS transits and more. Follow us as @Astroguyz as we look at these and other possibilities and tell our usual “tales of the saros”. And although this event marks the end of eclipse season, its only one of two such spans for 2014… tune in this October, when North America will be treated to another total lunar eclipse on the 8th and a partial solar eclipse on the 23rd… more to come! Send in those eclipse pics to the Universe Today Flickr community… you just might find yourself featured in this space!

Easter Sunday Space Station Rendezvous and Berthing for SpaceX Dragon Freighter Successful

SpaceX Dragon resupply spacecraft arrives for successful berthing and docking at the International Space Station on Easter Sunday morning April 20, 2014. Credit: NASA TV

The SpaceX 3 Dragon commercial cargo freighter successfully arrived at the International Space Station (ISS) on Easter Sunday morning, April 20, as planned and was deftly captured by Expedition 39 Commander Koichi Wakata at 7:15 a.m. EDT at the controls of the Canadian built robotic arm.

The next step due shortly is berthing of Dragon at the Earth facing port of the Harmony module at approximately 9:30 a.m. EDT.

Berthing was officially completed at 10:06 a.m. EDT while the massive complex was soaring 260 miles above Brazil.

This story is being updated as events unfold. The mission is the company’s third cargo delivery flight to the station.

The Dragon vehicle loaded with nearly 2.5 tons of science experiments and supplies moved ever so slowly closely to within grappling distance – dramatically backdropped with gorgeous and ever changing scenery of our Home Planet sliding below.

The million pound orbiting lab complex and free flying SpaceX Dragon were soaring some 260 miles above Egypt and the Nile River as the 57 foot long robotic arm grappled the resupply ship.

Dragon was approximately 30 feet (10 meters) away from the stations hull at the time of capture.

Wakata, of the Japan Aerospace Exploration Agency, was assisted by NASA astronaut Rick Mastracchio, while both were working from inside the 7 windowed Cupola robotics work station. Newly arrived NASA astronaut Steve Swanson observed the proceedings with a big smile.

“Congratulations to the entire ops team for the successful launch, rendezvous and capture of Dragon,” Wakata radioed mission control moments after the successful grapple.

“Great work catching the Dragon, enabling fantastic science,” radioed Capcom Steve Fisher from NASA Houston Mission Control.

Cheers and celebrations erupted at SpaceX Mission Control at the firms headquarters in Hawthorne, Calif.

Dragon arrived this morning following Friday afternoons, Apr 18, spectacular blastoff from Cape Canaveral, Fla, atop an upgraded SpaceX Falcon 9 booster.

A two day orbital chase ensued with a series of critical engine burns targeting the ISS for Easter Sunday’s rendezvous and docking activities.

Rick Mastracchio was at the controls for the actual berthing and latching in place at Harmony with Dragon’s Common Berthing Mechanism (CBM).

The berthing process started at about 9:30 a.m. EDT.

4 latches were driven for 1st stage of capture. Followed by all 16 bolts and latches in total during second stage capture to firmly hold Dragon in place.

The crew and mission control concluded the berthing procedure at 10:06 a.m. EDT flying over Brazil.

The next step is for the crew to pressurize the vestibule connecting Dragon to station.

Hatch opening is set to take place on Monday morning.

It’s a busy week ahead for the six person international crew representing the US, Russia and Japan.

A Russian Progress departs on Wednesday followed by the 2 person US spacewalk to replace the failed MDM unit.

Dragon will remain attached to the station until May 18.

The SpaceX-3 mission marks the company’s third operational resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016.

There are over 150 science experiments loaded aboard the Dragon capsule for research to be conducted by the crews of ISS Expeditions 39 and 40.

This unmanned SpaceX mission dubbed CRS-3 mission will deliver some 5000 pounds of science experiments, a pair of hi tech legs for Robonaut 2, a high definition Earth observing imaging camera suite (HDEV), a laser optical communications experiment (OPALS) and essential gear, the VEGGIE lettuce growing experiment, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.
