The three man crew of NASA’s Apollo 11 splashed down in the Pacific Ocean 45 years ago today on July 24, 1969 – successfully concluding Earth’s first journey to land humans on another world and return them safely to our Home Planet.

Apollo 11 Commander Neil Armstrong became the first human to set foot on the Moon on July 20, 1969 after he stepped off the footpad of the Lunar Module Eagle soon after the start of the moonwalk EVA at 10:39 p.m. EDT and onto the lunar surface with his left foot at the Sea of Tranquility at 10:56 p.m. EDT. Lunar Module (LM) pilot Buzz Aldrin followed soon thereafter. They came in peace for all mankind!

The magnificent Lunar landing feat accomplished by US Apollo 11 astronauts Neil Armstrong and Buzz Aldrin marks the pinnacle of Mankind’s most momentous achievement.

The Apollo 11 crew consisting of Neil Armstrong, Buzz Aldrin and Command module pilot Michael Collins splashed down safely at 12:50 p.m. EDT on July 24 about 900 miles southwest of Hawaii in the North Pacific Ocean while seated inside the Command Module Columbia dangling at the end of a trio of massive parachutes that slowed their descent through the Earth’s atmosphere.

After a mission duration of 8 days, 3 hours, 18 minutes, 35 seconds from launch to landing the Apollo 11 crew were plucked from the ocean by helicopters from the USS Hornet recovery ship after splashdown only 12 nautical miles (24 km) away.

They had to don protective biological isolation garments (BIGs) in case they were infected by some unknown and potentially hazardous “moon germs.” Of course there were no pathogens, but this was not definitely known at the time.

After their return to Earth, the trio was scrubbed with a disinfect solution of sodium hypochlorite and had to remain in quarantine for 21 days inside a 30 feet (9.1 m) long quarantine facility known as the Lunar Receiving Laboratory (LRL).

They were welcomed back to Earth by President Nixon aboard the USS Hornet.

We’ve chronicled the journey of Apollo 11 and lunar touchdown on July 20, 1969 as well as this week’s renaming of a historic human spaceflight facility at the Kennedy Space Center in honor of Mission Commander Neil Armstrong.

Armstrong passed away at age 82 on August 25, 2012 due to complications from heart bypass surgery. Read my prior tribute articles: here and here

Here we’ve collected a gallery of the mission and ocean splashdown that brought Apollo 11 to a close and fulfilled the lunar landing quest set by a young President John F. Kennedy early in the decade of the 1960s.

The trio blasted off atop a 363 foot-tall Saturn V rocket from Launch Complex 39A on their bold, quarter of a million mile moon mission from the Kennedy Space Center , Florida on July 16, 1969.

The three-stage Saturn V generated 7.5 million pounds of thrust and propelled the trio into space and immortality.

Read my story about the deep sea recovery of the Apollo 11 first stage F-1 engines in 2013 – here.

The crew arrived in lunar orbit three days later on July 19, 1969, inside the docked Apollo 11 Command/Service and Lunar Modules (CSM/LM).

Armstrong and Aldrin then moved into the Lunar Module, undocked and safely touched down at the Sea of Tranquility on the lunar surface on July 20, 1969 at 4:18 p.m EDT as hundreds of millions across the globe watched in awe.

Six hours later Armstrong climbed down the LM ladder and stepped onto the Moon and into immortality.

Armstrong’s first words:

“That’s one small step for [a] man, one giant leap for mankind.”

During their 2 ½ hour long moonwalk Armstrong and Aldrin unveiled a plaque on the side of the lunar module. Armstrong read the words;

“Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

The duo collected about 50 pounds (22 kg) of priceless moon rocks and set out the first science experiments placed by humans on another world. The moon rocks were invaluable in informing us about the origin of the Earth – Moon system.

Here is NASA’s restored video of the Apollo 11 EVA on July 20, 1969:

Video Caption: Original Mission Video as aired in July 1969 depicting the Apollo 11 astronauts conducting several tasks during extravehicular activity (EVA) operations on the surface of the moon. The EVA lasted approximately 2.5 hours with all scientific activities being completed satisfactorily. The Apollo 11 EVA began at 10:39:33 p.m. EDT on July 20, 1969 when Astronaut Neil Armstrong emerged from the spacecraft first. While descending, he released the Modularized Equipment Stowage Assembly on the Lunar Module’s descent stage.

Altogether Armstrong and Aldrin spent about 21 hours on the moon’s surface. Then they said goodbye to the greatest adventure and fired up the LM ascent engine to rejoin Michael Collins circling above in the Apollo 11 Command Module.

“The whole world was together at that particular moment,” says NASA Administrator Charles Bolden in a CNN interview. “In spite of all we are going through there is hope!”

Neck Of Rosetta’s ‘Rubby Duckie’ Comet Shows A Bright Ring

Rosetta imaged its target comet, Comet 67P/Churyumov-Gerasimenko, from about 3,417 miles (5,500 kilometers) away. The "neck" of the comet appears to be brighter than the rest of the nucleus. Credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

Rosetta’s “rubber duckie” comet appears to be wearing a collar! New images of Comet 67P/Churyumov-Gerasimenko from the spacecraft, which is speeding towards an orbit of the comet next month, show that the “neck” region of the nucleus appears to be brighter than the rest.

Last week, images from the spacecraft revealed that the comet likely has a “contact binary” nucleus, meaning that there are two parts of the nucleus that are just barely joined together under low gravity. There are many theories for why this happened, but it will take a closer examination to begin to come up with answers. The shape of the nucleus reminds many of a rubber duckie.

As for why the “neck” region appears brighter, that’s not known right now. There could be different grains in that region of the nucleus, or it could be some feature of the surface. Or perhaps it is a different type of material there. The scientists plan to get more spectral information from this region in the coming weeks, which could reveal what elements are there.

“Even though the images taken from a distance of 5500 kilometers are still not highly resolved, the scientists feel remotely reminded of comet 103P/Hartley,” stated the Max Planck Institute for Solar System Research.

“This body was visited in a flyby by NASA’s EPOXI mission in 2010. While Hartley’s ends show a rather rough surface, its middle is much smoother. Scientists believe this waist to be a gravitational low: since it contains the body’s center of mass, emitted material that cannot leave the comet’s gravitational field is most likely to be re-deposited there.”

Rosetta is expected to arrive at the comet on August 6, and to send out its spider-like lander (Philae) in November. The spacecraft will remain with the comet through its closest approach to the sun in 2015, between the orbits of Earth and Mars.

Risk Reduction Milestone Tests Move Commercial Dream Chaser Closer to Critical Design Review and First Flight

Dream Chaser commercial crew vehicle built by Sierra Nevada Corp docks at ISS

The winged Dream Chaser mini-shuttle under development by Sierra Nevada Corp. (SNC) has successfully completed a series of risk reduction milestone tests on key flight hardware systems thereby moving the private reusable spacecraft closer to its critical design review (CDR) and first flight under NASA’s Commercial Crew Program aimed at restoring America’s indigenous human spaceflight access to low Earth orbit and the space station.

SNC announced that it passed NASA’s Milestones 9 and 9a involving numerous Risk Reduction and Technology Readiness Level (TRL) advancement tests of critical Dream Chaser® systems under its Commercial Crew Integrated Capability (CCiCap) agreement with the agency.

Seven specific hardware systems underwent extensive testing and passed a major comprehensive review with NASA including; the Main Propulsion System, Reaction Control System, Crew Systems, Environmental Control and Life Support Systems (ECLSS), Structures, Thermal Control (TCS) and Thermal Protection Systems (TPS).

The tests are among the milestones SNC must complete to receive continued funding from the Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.

Over 3,500 tests were involved in completing the Risk Reduction and TRL advancement tests on the seven hardware systems whose purpose is to significantly retire overall program risk enable a continued maturation of the Dream Chaser’s design.

Dream Chaser is a reusable lifting-body design spaceship that will carry a mix of cargo and up to a seven crewmembers to the ISS. It will also be able to land on commercial runways anywhere in the world, according to SNC.

“By thoroughly assessing and mitigating each of the previously identified design risks, SNC is continuing to prove that Dream Chaser is a safe, robust, and reliable spacecraft,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems, in a statement.

“These crucial validations are vital steps in our Critical Design Review and in showing that we have a very advanced and capable spacecraft. This will allow us to quickly and confidently move forward in restoring cutting-edge transportation to low-Earth orbit from the U.S.”

The Dream Chaser is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the International Space Station by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.

The SpaceX Dragon and Boeing CST-100 ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around August/September 2014.

“Our partners are making great progress as they refine their systems for safe, reliable and cost-effective spaceflight,” said Kathy Lueders, manager of NASA’s Commercial Crew Program.

“It is extremely impressive to hear and see the interchange between the company and NASA engineering teams as they delve into the very details of the systems that help assure the safety of passengers.”

After completing milestones 9 and 9a, SNC has now received 92% of its total CCiCAP Phase 1 NASA award of $227.5 million.

“We are on schedule to launch our first orbital flight in November of 2016, which will mark the beginning of the restoration of U.S. crew capability to low-Earth orbit,” says Sirangelo.

Dream Chaser measures about 29 feet long with a 23 foot wide wing span and is about one third the size of NASA’s space shuttle orbiters.

It will launch atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Launch Complex 41 in Florida.

Since the forced shutdown of NASA’s Space Shuttle program following its final flight in 2011, US astronauts have been 100% dependent on the Russians and their cramped but effective Soyuz capsule for rides to the station and back – at a cost exceeding $70 million per seat.

The Dream Chaser design builds on the experience gained from NASA Langley’s earlier exploratory engineering work with the HL-20 manned lifting-body vehicle.

Historic Human Spaceflight Facility at Kennedy Renamed in Honor of Neil Armstrong – 1st Man on the Moon

45 years ago on July 20, 1969, NASA astronaut and Apollo 11 Commander Neil Armstrong became the first human being to set foot on another celestial body when he stepped off the Apollo 11 Lunar Module Eagle and onto our Moon’s utterly alien surface.

Today, July 21, 2014, NASA officially renamed a historic facility at the Kennedy Space Center vital to human spaceflight in honor of Neil Armstrong during a a 45th anniversary ceremony at what until today was known as the ‘Operations and Checkout Building’ or O & C.

On that first moonwalk, Armstrong was accompanied by fellow NASA astronaut Buzz Aldrin on a two and a half hour excursion that lasted into the early morning hours of July 21. They came in peace representing all mankind.

Today’s ceremony was broadcast on NASA TV and brought together numerous dignitaries including Armstrong’s surviving crewmates Buzz Aldrin and Command Module pilot Mike Collins, Apollo 13 Commander Jim Lovell who was also Apollo 11’s backup commander, NASA Administrator Charlie Bolden, Kennedy Space Center Director Bob Cabana, and Armstrong’s family members including his sons Rick and Mark Armstrong who all spoke movingly at the dedication.

They were joined via a live feed from space by two NASA astronauts currently serving aboard the International Space Station (ISS) – Expedition 40 crew member Rick Wiseman and Commander Steve Swanson.

The backdrop for the ceremony was the Orion crew capsule, NASA’s next generation human rated spaceflight vehicle which is currently being assembled in the facility and is set to launch on its maiden unmanned test flight in December 2014. Orion will eventually carry US astronauts on journey’s to deep space destinations to the Moon, Asteroids and Mars.

Many of Armstrong’s colleagues and other officials working on Orion and NASA’s human spaceflight missions also attended.

Apollo 11 Commander Neil Armstrong inside the Lunar Module

The high bay of what is now officially the ‘Neil Armstrong Operations and Checkout Building’ was built in 1964 and previously was known as the Manned Spacecraft Operations Building.

It has a storied history in human spaceflight. It was used to process the Gemini spacecraft including Armstrong’s Gemini 8 capsule. Later it was used during the Apollo program to process and test the command, service and lunar modules including the Apollo 11 crew vehicles that were launched atop the Saturn V moon rocket. During the shuttle era it housed the crew quarters for astronauts KSC training and for preparations in the final days leading to launch.

“45 years ago, NASA’s journey to land the first human on the Moon began right here,” NASA Administrator Charlie Bolden said at the ceremony. “It is altogether fitting that today we rename this facility the Neil Armstrong Operations and Checkout Building. Throughout his life he served his country as an astronaut, an aerospace engineer, a naval aviator, a test pilot and a university professor, and he constantly challenged all of us to expand the boundaries of the possible.”

“He along with his crewmates, Buzz Aldrin and Michael Collins, are a bridge from NASA’s historic journey to the moon 45 years ago to our path to Mars today.”

The Apollo 11 trio blasted off atop a 363 foot-tall Saturn V rocket from Launch Complex 39A on their bold, quarter of a million mile moon mission from the Kennedy Space Center , Florida on July 16, 1969 to fulfill the lunar landing quest set by President John F. Kennedy early in the decade.

Armstrong and Aldrin safely touched down at the Sea of Tranquility on the lunar surface on July 20, 1969 at 4:18 p.m EDT as hundreds of millions across the globe watched in awe.

“Houston, Tranquility Base here. The Eagle has landed !,” Armstrong called out and emotional applause erupted at Mission Control – “You got a bunch of guys about to turn blue.”

Armstrong’s immortal first words:

“That’s one small step for [a] man, one giant leap for mankind.”

During their 2 ½ hours moonwalk Armstrong and Aldrin unveiled a plaque on the side of the lunar module. Armstrong read the words;

“Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

Here is NASA’s restored video of the Apollo 11 EVA on July 20, 1969:

Armstrong passed away at age 82 on August 25, 2012 due to complications from heart bypass surgery. Read my prior tribute articles: here and here

Michael Collins concluded the ceremony with this tribute:

“He would not have sought this honor, that was not his style. But I think he would be proud to have his name so closely associated with the heart and the soul of the space business.”

“On Neil’s behalf, thank you for what you do every day.”

Man first walked on the Moon 45 years ago today on July 20, 1969 when American astronauts Neil Armstrong and Buzz Aldrin opened the hatch to the Apollo 11 Lunar Module Eagle, climbed down the ladder and set foot on the surface – marking mankind’s greatest achievement. They came in peace for all mankind!

You can relive the historic moment with the gallery of Apollo 11 NASA images collected here and by watching NASA’s restored video of the moonwalk, or extravehicular activity (EVA) by Armstrong and Aldrin – watch video below. The Apollo 11 EVA began at 10:39:33 p.m. EDT.

NASA TV is also broadcasting a replay of the historic moonwalk tonight (July 20) to commemorate the anniversary starting at 10:39 p.m. EDT, with the restored footage of Armstrong and Aldrin’s historic steps on the lunar surface.

You can view the NASA TV Apollo 11 EVA webcast – here.

The Eagle had landed on the Moon’s desolate surface on the Sea of Tranquility (see map below) barely 6 hours earlier at 4:18 p.m EDT. And only 30 seconds of fuel remained as Armstrong searched for a safe landing spot.

Neil Armstrong was the commander of the three man crew of Apollo 11, which included fellow moonwalker Buzz Aldrin and Command module pilot Michael Collins.

Here is NASA’s restored video of the Apollo 11 EVA on July 20, 1969:

Altogether a dozen Americans have walked on the Moon during NASA’s five additional Apollo lunar landing missions. No human has returned since the final crew of Apollo 17 departed the Moon’s surface in December 1972.

One legacy of Apollo is the International Space Station (ISS) where six astronauts and cosmonauts work together on science research to benefit mankind.

Notably, the Cygnus commercial cargo ship berthed at the ISS on the 45th anniversary of the Apollo 11 liftoff bringing over 3600 pounds of science experiments and supplies to the station.

NASA’s next big human spaceflight goals are building commercial ‘space taxis’ to low Earth orbit in this decade, an asteroid retrieval mission in the 2020s and voyages to Mars in the 2030s using the new SLS rocket and Orion deep space crew capsule currently under development.

Sparks Fly on Mars as Curiosity Laser Blasts Red Planet Rock – Photos/Video

Curiosity has zapped hundreds of Red Planet rocks with her powerful laser blaster during her lifetime and has now caught the sparks flying for the first time as they happened – as seen in new photos and video above and below released this week by NASA.

As the NASA rover’s million watt Chemistry and Camera (ChemCam) instrument fired multiple laser shots at a rock fortuitously named “Nova” the team commanded her arm-mounted Mars Hand Lens Imager (MAHLI) high resolution imaging camera to try and capture the action as it occurred, for the first time. And they succeeded.

Curiosity blasted the baseball sized “Nova” rock target over 100 times on July 12, 2014, or Sol 687.

Since the nail biting touchdown nearly two years ago on Aug. 5, 2012 inside Gale Crater, ChemCam has aimed the laser instrument at more than 600 rock or soil targets and fired more than 150,000 laser shots.

Here’s a NASA/JPL video showing the laser flash:

ChemCam is used to determine the composition of Martian rocks and soils at a distance of up to 25 feet (8 meters) yielding preliminary data for the scientists and engineers to decide if a target warrants up close investigation and in rare cases sampling and drilling activities.

ChemCam works through a process called laser-induced breakdown spectroscopy. The laser hits a target with pulses to generate sparks, whose spectra provide information about which chemical elements are in the target.

Successive laser shots are fired in sequence to gradually blast away thin layers of material. Each shot exposes a slightly deeper layer for examination by the ChemCam spectrometer.

As Curiosity fired deeper into “Nova” it showed an increasing concentration of aluminum as the sequential laser blasts penetrated through the uninteresting dust on the rock’s surface. Silicon and sodium were also detected.

“This is so exciting! The ChemCam laser has fired more than 150,000 times on Mars, but this is the first time we see the plasma plume that is created,” said ChemCam Deputy Principal Investigator Sylvestre Maurice, at the Research Institute in Astrophysics and Planetology, of France’s National Center for Scientific Research and the University of Toulouse, France, in a statement.

“Each time the laser hits a target, the plasma light is caught and analyzed by ChemCam’s spectrometers. What the new images add is confirmation that the size and shape of the spark are what we anticipated under Martian conditions.”

The SUZ sized rover is driving as swiftly as possible to the base of Mount Sharp which dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Year 1 on Mars, Earth’s emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the minerals necessary to support microbial life in the ancient past when Mars was far wetter and warmer billions of years ago.

To date, Curiosity’s odometer totals over 5.1 miles (8.4 kilometers) since landing inside Gale Crater on Mars in August 2012. She has taken over 166,000 images.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the treacherous sand dunes at the foothills of Mount Sharp sometime later this year.

Stay tuned here for Ken’s continuing Curiosity, Opportunity, Orion, SpaceX, Boeing, Orbital Sciences, commercial space, MAVEN, MOM, Mars and more planetary and human spaceflight news.

How Humanity’s Next Moon Explorers Could Live In Lunar ‘Pits’

Just look at that new video from NASA showing the first moon landing site in three dimensions. It’s tempting to touch on the surface nearby the Eagle lander there in the center and do some prospecting.

You’ll notice a lot of craters in that video, which is based on Lunar Reconnaissance Orbiter data. Across the moon’s surface, a separate study saw the spacecraft investigate 200 extremely steep-walled craters, known as “pits”.

These would be fascinating places to send astronauts for scientific study. Not only that, they’re actually one of the safest spots possible on the moon, according to a new study.

“Pits would be useful in a support role for human activity on the lunar surface,” stated lead researcher Robert Wagner of Arizona State University.

“A habitat placed in a pit — ideally several dozen meters back under an overhang — would provide a very safe location for astronauts: no radiation, no micrometeorites, possibly very little dust, and no wild day-night temperature swings.”

And if you look at the picture below, you can see at least one of those pits is in the Sea of Tranquility — the approximate landing area where Apollo 11 touched down 45 years ago this week. The pits were found mainly using a computer algorithm that scanned LRO photos, although a few of the craters were previously identified with the Japanese Kaguya spacecraft.

Large craters or lunar “seas” (ancient, solidified lava flows) are the locations where most of these pits are found. How they were formed is being investigated, but there are some hypotheses. Perhaps a meteorite impact caused a collapse, or perhaps molten rock flows under the surface gradually lost their lava, leaving voids.

To learn more, the researchers say more LRO images would be great (only 40% of the surface imaged had the appropriate lighting conditions for this study) and in the future, we’d need to get much closer-up than pictures taken from orbit.

“The ideal follow-up, of course, would be to drop probes into one or two of these pits, and get a really good look at what’s down there,” added Wagner.

“Pits, by their nature, cannot be explored very well from orbit — the lower walls and any floor-level caves simply cannot be seen from a good angle. Even a few pictures from ground-level would answer a lot of the outstanding questions about the nature of the voids that the pits collapsed into. We’re currently in the very early design phases of a mission concept to do exactly this, exploring one of the largest mare pits.”

Cargo Ship’s Fiery Demise Could Help Predict What Happens When The Space Station Burns Up

It’s sad to think about, but there will be a day sometime when the International Space Station makes its final journey — a destructive re-entry into Earth’s atmosphere. Historically, it’s been hard to break up large pieces of space hardware safely. Pieces of the Skylab space station famously rained down in Australia, while Mir’s demise triggered warnings across its re-entry path.

The European Space Agency sees an opportunity to gather more information for this future use: closely watching what happens when the final Automated Transfer Vehicle (ATV), Georges Lemaître, goes to the International Space Station and has its planned breakup in the atmosphere following the shipment.

They plan to record its last moments using a heat-seeking camera on the inside of the spacecraft. This sort of thing has been done before with NASA and the Japanese Aerospace Exploration Agency, but this will be a first for ESA.

“The data should also hold broader value,” stated Neil Murray, who is leading the project at the European Space Agency (ESA).

“The project is proceeding under our ‘Design for Demise’ effort to design space hardware in such a way that it is less likely to survive reentry and potentially endanger the public. Design for Demise in turn is part of the agency’s clean space initiative, seeking to render the space industry more environmentally friendly in space as well as on Earth.”

The camera will ride inside, bolted to a rack, and transmit the last 20 seconds of its lifetime to a special Reentry Satcom capsule that is designed to survive the breakup. The data will in turn be sent to Earth using an Iridium satellite.

While the SatCom will be protected by a heatshield, the challenge will be transmitting the information through the plasma generated as it falls at 6 to 7 kilometers (3.7 to 4.3 miles) a second. The breakup will happen at 80 kilometers (50 miles) and the plasma will be there until below an altitude of about 40 kilometers (25 miles), ESA stated.

“The fall will generate high-temperature plasma around it, but signals from its omnidirectional antenna should be able to make it through any gap in the plasma to the rear,” the agency added.

Georges Lemaître is expected to launch later this month and last six months in space before re-entry.

Long lineups at Cape Kennedy. Every television channel playing the same breathless coverage. Shots of rockets, of men in spacesuits, and of course the ghostly image of people stepping on to the moon for the first time.

If you’re old enough to remember Apollo 11, this documentary above should bring back a lot of warm memories. And even if you’re not (which includes the writer of this article), it gives you a small taste of just how awesome the atmosphere must have been.

“Moonwalk One” is a 1970 documentary directed by Theo Kamecke, and now we’re lucky enough to watch it for free on NASA’s YouTube channel. As soon as you can spare a couple of hours, do watch it.

The first few minutes alone are fun, with dramatic shots of Stonehenge and the Saturn V contrasted with frantic shots of traffic and dancing and signs all over the Cape.
