Find a Lunar Cave - Think about designing for that cave - 3D printing - Neri Oxman


Using caves on the Moon for habitats plays a part in science fiction and possibly for real if we ever go back to stay.  Finding them and checking out their usefulness will be necessary and Jaro alerted me to the below PDF article.

When you decide to move it will take a bit of fixing up and I have been viewing some videos of Neri Oxman of MIT's Media Lab using 3D printers. Could I use any of her ideas.  Look around and see what mother nature has done and be inspired and creative.

SKYLIGHT: MISSION TO INVESTIGATE AND MODEL A LUNAR PIT. H. L. Jones1, K. M. Peterson2, W. L. Whittaker1,2, and U. Y. Wong1 1Robotics Institute, Carnegie Mellon University (5000 Forbes Ave, Pittsburgh, PA 15213, {hlj|red|uyw}@cs.cmu.edu), 2Astrobotic Technology, Inc. (2515 Liberty Ave, Pittsburgh, PA 15222, kev-in.peterson@astrobotictech.com).

Introduction: Caves on planetary bodies beyond Earth have always been of great interest for science and exploration, but for many years there was no known way to enter. Unprecedented high-resolution imagery from the Lunar Reconnaissance Orbiter has revealed pits that are believed to be skylights – features formed by partial cave ceiling collapse that provide access into caves [1],[2]. Skylights have also been discovered on Mars [3], and similar features may exist elsewhere in the solar system [1]. Discovery of these features changes everything. The Skylight mission takes the next step to closely investigate one of these pits.
Mission Objectives: The Skylight mission seeks to answer science and exploration questions about the-se newly discovered lunar skylights. The objectives of the mission are to:
1. provide multi-perspective close-up images of a lunar pit,
2. build a detailed, high quality 3D model of the pit, and
3. survey the terrain surrounding the pit.

Mission Decription: The Skylight mission targets the Marius Hills Hole (MHH) in the Marius Hills re-gion of Oceanus Procellarum at 14.2°N, 303.3°E [4]. This pit is selected because of its location on the lunar near side, facilitating mission operations without re-quirement for installation of expensive communication infrastructure, as well as the indications of lava tubes in surrounding terrain.

Voyager: Looking Backward and Forward



A paper about the Voyager missions was given a headline that announced that Voyager 1 had left the Solar System and then was revised to be a bit less sensational.  Please do read Paul Gilster's blog, a snippet seen below.

Voyager: Looking Backward and Forward

by PAUL GILSTER on MARCH 21, 2013
The Voyager spacecraft have run into their share of problems as they move toward true interstellar space, but on the whole their continued operations have been a testament to what well designed equipment can do. Voyager 2’s camera platform locked for a time not long after the Saturn flyby but controllers were able to restore the system by experimenting with similar actuators on Earth. Three years ago the craft began having data problems resulting from a flipped bit in an onboard computer but a reset from Earth corrected the fault. Even the failure of the primary radio receiver not long after launch was resolved by the use of the onboard backup.
Obviously both craft are living on borrowed time as the power output of their radioisotope thermoelectric generators (RTGs) continues to decline, but we should still be getting signals for another decade or so. With the Voyagers now on what is designated their ‘interstellar mission,’ it’s pleasing to note that Alpha Centauri is the guide star that Voyager 1 used to reorient itself to resume transmissions to Earth following 2011 maneuvering to allow better detection of the solar wind. We continue to push deeper into a region of space that is now little understood.
Leaving the Solar System
Yesterday’s brief skirmish over Voyager 1’s true situation tells us how much we have to learn about the Solar System’s edge. A paper by William Webber (New Mexico State) and the late Frank McDonald (University of Maryland) reported that a sudden change in cosmic rays detected by Voyager 1 last summer showed that the spacecraft was in a new region of the Solar System they called the ‘heliocliff.’ What evidently confused matters was that the American Geophysical Union, publisher of Geophysical Review Letters — the publication at which the paper had been accepted — sent out a news release saying the craft had left the Solar System.
While the cosmic ray changes were marked, with galactic cosmic ray intensity suddenly doubling last August, Caltech’s Ed Stone issued a statement saying that a change in the magnetic field will be the true indication of Voyager 1’s arrival in interstellar space. No such change has yet been detected, and the AGU soon revised the news release headline to say that the spacecraft had ‘entered a new region of space.’ The ‘heliocliff,’ in other words, is apparently the same region that NASA scientists had already noted as a previously unknown ‘highway’ of magnetic particles. Nancy Atkinson straightened all this out quickly on Universe Today.

CORRECTED PRESS RELEASE
Please note that the headline on this release has been changed to better represent the findings reported in the study

Voyager 1 has entered a new region of space, sudden changes in cosmic rays indicate

20 March 2013
AGU Release No. 13-11
For Immediate Release
WASHINGTON – Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.
The heliosphere is a region of space dominated by the Sun and its wind of energetic particles, and which is thought to be enclosed, bubble-like, in the surrounding interstellar medium of gas and dust that pervades the Milky Way galaxy.
On August 25, 2012, NASA's Voyager 1 spacecraft measured drastic changes in radiation levels, more than 11 billion miles from the Sun. Anomalous cosmic rays, which are cosmic rays trapped in the outer heliosphere, all but vanished, dropping to less than 1 percent of previous amounts. At the same time, galactic cosmic rays – cosmic radiation from outside of the solar system – spiked to levels not seen since Voyager's launch, with intensities as much as twice previous levels.
The findings have been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.
"Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere," said Bill Webber, professor emeritus of astronomy at New Mexico State University in Las Cruces. He calls this transition boundary the "heliocliff."
In the GRL article, the authors state: "It appears that [Voyager 1] has exited the main solar modulation region, revealing [hydrogen] and [helium] spectra characteristic of those to be expected in the local interstellar medium."
However, Webber notes, scientists are continuing to debate whether Voyager 1 has reached interstellar space or entered a separate, undefined region beyond the solar system.
"It's outside the normal heliosphere, I would say that," Webber said. "We're in a new region. And everything we're measuring is different and exciting."
The work was funded by NASA's Jet Propulsion Laboratory in Pasadena, Calif.

Voyager 1 has left the solar system — almost

The American Geophysical Union announces that the space probe has become the first man-made object to enter interstellar space, only to backtrack when NASA scientists and others dispute the claim.

A NASA illustration depicts one of the twin Voyager spacecraft. NASA scientists Wednesday disputed an announcement that Voyager 1 had moved beyond the solar system and into interstellar space. (NASA /August 9, 2002)

March 20, 20138:09 p.m.

It was welcome news to Earthlings: The Voyager 1 spacecraft had seemingly crossed a momentous threshold and become the first man-made object to enter interstellar space.
"Voyager 1 has left the solar system," the American Geophysical Union declared Wednesday in a news release. An accompanying study published online in the organization's journal, Geophysical Research Letters, also contained an unusually sentimental end note declaring that "we did it. Bon Voyage!"
Alas, the elation that spread through news and social media was short-lived. Voyager 1 was still in the neighborhood,NASA said, even after traveling for more than 35 years. Then the American Geophysical Union press office issued a correction of its headline, omitting any reference to the spacecraft having departed "the solar system."

What an incredible adventure. We are right now onboard the Seabed Worker headed back to Cape Canaveral after finishing three weeks at sea, working almost 3 miles below the surface. We found so much. We’ve seen an underwater wonderland – an incredible sculpture garden of twisted F-1 engines that tells the story of a fiery and violent end, one that serves testament to the Apollo program. We photographed many beautiful objects in situ and have now recovered many prime pieces. Each piece we bring on deck conjures for me the thousands of engineers who worked together back then to do what for all time had been thought surely impossible.

Welcome to the Apollo 11 F-1 Engine Recovery Website

March 28, 2012
The F-1 rocket engine is still a modern wonder — one and a half million pounds of thrust, 32 million horsepower, and burning 6,000 pounds of rocket grade kerosene and liquid oxygen every second. On July 16, 1969, the world watched as five particular F-1 engines fired in concert, beginning the historic Apollo 11 mission. Those five F-1s burned for just a few minutes, and then plunged back to Earth into the Atlantic Ocean, just as NASA planned. A few days later, Neil Armstrong stepped onto the moon.

snip
--------------------------------------------------------

Wikipedia link
- LRK -

--------------------------------------------------------
The F-1 is a rocket engine developed by Rocketdyne and used in the Saturn V. Five F-1 engines were used in the S-IC first stage of each Saturn V, which served as the main launch vehicle in the Apollo program. The F-1 is still the most powerful single-chamber liquid-fueled rocket engine ever developed.[1] The RD-170 has slightly more thrust, using a cluster of four smaller combustion chambers and nozzles.[2]

History

The F-1 was originally developed by Rocketdyne to meet a 1955 US Air Force requirement for a very large rocket engine. The eventual result of that requirement was two different engines, the E-1 and the much larger F-1. The E-1, although successfully tested in static firing, was quickly seen as a technological dead-end and was abandoned for the larger, more powerful F-1. The Air Force eventually halted development of the F-1 because of a lack of requirement for such a large engine. However, the recently created National Aeronautics and Space Administration appreciated the usefulness of an engine with so much power and contracted Rocketdyne to complete its development. Test firings of F-1 components had been performed as early as 1957. The first static firing of a full-stage developmental F-1 was performed in March 1959. The first F-1 was delivered to MSFCin October 1963. In December 1964 the F-1 completed flight-rating tests. Testing continued at least through 1965.[3]
For seven years of development F-1 tests revealed serious combustion instability problems which would sometimes cause catastrophic failure.[4] Progress on this problem was initially slow, as the problem onset was intermittent and unpredictable. Oscillations of 4 kHz with harmonics to 24 kHz were noticed. Eventually engineers developed a technique of detonating small explosive charges (which they called "bombs") outside the combustion chamber through a tangential tube (RDX, C4 or black powder were used) while the engine was firing, which allowed them to determine exactly how the running chamber responded to variations in pressure and to determine how to nullify these oscillations. The designers could then quickly experiment with different co-axial fuel-injector designs to obtain the one most resistant to instability. These problems were addressed from 1959 through 1961. Eventually the engine's combustion was so stable it would self-damp artificially induced instability within 1/10 of a second.

SpaceX Update: Dragon Now Mated to Space Station
 Posted Sunday, March 3, 2013, at 12:17 PM

Well, that was fast! This morning, the SpaceX Dragon capsule was successfully berthed to the International Space Station. After all the drama that started this mission, the successful orbital mating brought cheers—and a sigh of relief—across NASA.
The capsule began maneuvering toward the ISS last night, and took several hours to approach. At 10:31 UTC (05:31 Eastern US time), when it was a few meters away, the astronauts used the Canadarm2—the station’s large, articulated robot arm—to grapple the capsule. After a few hours of checkouts, the arm brought Dragon in, and the capsule was berthed at 13:56 UTC (08:56 Eastern).

SpaceX Dragon successfully docks with International Space Station

Will spend the next 22 days attached to the ISS before returning.
by  - Mar 3 2013, 10:45am PST

After some issues with its thrusters hours after launch, the SpaceX Dragon capsule successfully docked with the International Space Station. NASA reported that the capsule attached to the Harmony module of the ISS at 8:56am EST Sunday morning, with the door set to be opened on Monday morning.

Dragon took off from Cape Canaveral on Friday morning and reached orbit without a hitch, but a pressure problem prevented the thruster pods from initializing once orbit was attained. The four pods then gradually came online over the course of the day. Two pods are needed to get Dragon to the ISS with a third pod necessary for successfully maneuvering once the station is reached.

Loaded with nearly 1,270 pounds of supplies (575kg, to be exact), Dragon will spend the next 22 days docked with the ISS. On its return, the capsule will carry more than 1,200 kg of cargo, according to NASA. Included in the return payload will be seedlings and metal mixtures that spent time in low gravity, along with biological samples taken from the crew.

Dragon is a free-flying, reusable spacecraft developed by SpaceX under NASA's Commercial Orbital Transportation Services (COTS) program. Initiated internally by SpaceX in 2005, the Dragon spacecraft is made up of a pressurized capsule and unpressurized trunk used for Earth to LEO transport of pressurized cargo, unpressurized cargo, and/or crew members.

In May 2012, SpaceX made history when its Dragon spacecraft became the first commercial vehicle in history to successfully attach to the International Space Station. Previously only four governments -- the United States, Russia, Japan and the European Space Agency -- had achieved this challenging technical feat. SpaceX has now begun regular missions to the Space Station, completing its first official resupply mission in October 2012.

BREAKING: After Initial Problems, SpaceX Dragon Now Looking Good On Orbit
 | 
Posted Friday, March 1, 2013, at 4:25 PM





A dramatic series of events unfolded this morning shortly after the private commercial company SpaceX launched their Dragon capsule into space. This launch was part of the second of 12 planned missions to bring supplies and equipment to the International Space Station (ISS).

To be clear, things are looking good now, and it looks like the mission will proceed. Just not quite as planned.

Launch, and the Emergence of the Problem

The launch, using the SpaceX Falcon 9 rocket, was essentially flawless. The rocket performed beautifully and was able to cleanly insert the Dragon capsule into the desired orbit

However, shortly thereafter there was a problem. The first indication was that the solar panels—which provide power to the capsule during the mission—did not deploy as they were supposed to, which should happen about 10 minutes into the flight. There is a battery onboard that can provide power for only 12—14 hours, so this was worrisome.
However, news soon came down that the thrusters on the capsule were not working; the tanks containing the oxidizer (used to ignite the fuel) were not pressurizing correctly. The thrusters are small rockets that can be used to change the orbit of Dragon as well as maneuver it on orbit. These are mission-critical: without them, the mission cannot proceed.

This Is How Dennis Tito Plans To Send People to Mars
  • By Keith Cowing
  • Posted Wednesday, February 27, 2013

---------
If Dennis Tito has his way, two people will leave our planet in January 2018 and make a trip to Mars and back. Tito will be footing much of the bill himself. This mission won't stop at Mars, but rather, will do a quick flyby.

Unlike the spate of space commerce companies that have flashed on and off the news in recent months, this effort has substantial cash behind it - at the onset. Also, unlike these previously announced efforts, this is not being done by a company that needs to eventually return a profit to its investors. Instead, it is being spearheaded by a non-profit organization, the Inspiration Mars Foundation.

Tito's mission will be facilitated by donors - not investors. And no, he will not be part of the crew.
snip
Update: this paper is now online at Inspiration Mars Foundation.

The core premise of this initial mission concept is to use an upgraded SpaceX Dragon capsule as the habitable volume for the entire mission. This spacecraft would be launched on a SpaceX Falcon Heavy and follows an optimized free-return trajectory to Mars and back. As outlined in the paper, this conceptual mission would depart Earth on 5 Jan 2018, reach Mars on 20 August 2018, and return to Earth on 21 May 2019.

Dennis Tito’s mission to Mars: Launching in 2018 for the children (and to beat China)
By Brian Vastag,February 27, 2013

Millionaire space tourist Dennis Tito has a vision to send two Americans to Mars on a high-risk, budget-class, 501-day journey that would — if achieved — smash the barrier to deep space.

The proposed passengers are a middle-aged married couple, handy with tools and not prone to claustrophobia.

The Inspiration Mars Mission for America would launch, by necessity of orbital mechanics, on Jan. 5, 2018.

There is no spaceship yet, and little notion of a budget. There is no funding beyond a two-year research and development commitment by Tito. But the wealthy former rocket scientist and financier has assembled a team of credentialed advisers and plotted a mission that teeters, outside experts say, on the edge of credibility.

“It’s about inspiring the children,” Tito said at a news conference Wednesday to announce the scheme.

Moments earlier, the onetime flier to the international space station — he paid $20 million to go there in 2001 — had lambasted what he characterized as a four-decade stagnation in the U.S. human spaceflight program.

Three years ago, President Obama touted a possible NASA Mars landing in the mid-2030s.

“I’ll be 95 years old,” Tito said. “I don’t want to wait until that time.”

But there will be no landing on Tito’s mission. No footprints and flags in ruddy soil, no rock-grabbing, no search for Martian life.

Eight months after launch, Mars will loom, then vanish in the rearview mirror.

Tito said he will sell media rights. The Mission for America might become the Red Bull Mission to Mars, the Cool Ranch Doritos Mars Shot.

Martian dreams
Dennis Tito's mission to Mars

HOW times change. In 1952 Wernher von Braun, the ex-Nazi rocket engineer recruited by the Americans after the second world war, published a book called “The Mars Project”. In it, he detailed his plans for the human exploration of Mars. Ten ships, assembled in Earth orbit, would burn 5m tonnes of rocket fuel carrying a crew of 70 to the planet. On arrival, ground crawlers would carry the crew from their polar landing site to the equator, where a permanent base would be built. You can only imagine the price-tag for such a project, but suffice to say that only a superpower could have even dreamed of paying for it.

Six decades later, on February 27th, Dennis Tito, an American investment manager and space enthusiast who, in 2001, became the world’s first space tourist, unveiled his own plan. Inspiration Mars is a more modest affair. If all goes to plan, in January 2018 a single, small spaceship, carrying two crew members, will blast off for a 501-day trip to Mars and back. If it arrives safely, there are no plans to land. Instead, the idea is merely to fly around the planet and then head back to Earth. Unlike von Braun’s project, little government involvement will be necessary. Mr Tito hopes to pay for Inspiration Mars with a mix of his own money, donations from the public and the sale of media rights.

That is not to say that Mr Tito’s plan is timid. On the contrary: it is eye-wateringly (or, as one colleague puts it, “bowel-looseningly”) bold. Although endless studies have been done on how it might be possible to ferry humans to Mars, no one has ever attempted it. Mr Tito’s launch date is fixed, for it is designed to take advantage of a rare period of orbital proximity between Mars and Earth. If he misses his deadline, another opportunity will not present itself until 2031. That gives the team just under five years to design the mission, specify a spacecraft, find a rocket to launch it on, select a crew and carry out all the necessary checks and double-checks. And, without the financial muscle of a nation-state behind him, all this must be done on a budget.

snip
--------------------------------------------

Well you may have your own thoughts about such a long trip in close quarters. I would think much like the early sailors exploring unknown oceans.  Much risk to be accepted.
