We call this telerobotics at JSC (i.e half teleoperation, half robotics). It is a problem that is very difficult, as you must be able to do both autonomy and teleoperation and be smart about when and how to switch modes. Most of the work is centered on teleoperation and on robotics at the centers. I am working on a KC-135 experiment for this fiscal year to take an arm and a vision system and test grasping of polyhedra in microgravity with vision as the primary input. This is a tough problem and one that needs to be solved to make lots of missions less expensive.

Because the spacers were not present, the mirror was figured perfectly, but to the wrong focal point, outside the range of the Hubble's focusing apperatus. This error would have shown up had the entire telescope been tested as a whole prior to launch.

In a 0.2 atm 100% O2 environment things burn just like they do on the ground. In a 1atm 100% O2 atm things burn much better, people get ill after a while and so on. The Appolo capsule that burnt had 1atm of pure O2 on the pad, which would have been reduced to 0.2atm after launch. Later Appolo designs used 1atm of air on the pad, reducing to 0.2atm of O2 after launch. There are possible physiological problems with breathing 0.2atm oxygen for a long (weeks) period, but they are associated with the low total pressure rather than the purity of the gas. ------------------------------ Date: Tue, 10 Nov 92 23:27:44 EST From: John Roberts Subject: Low-pressure O2 atmosphere -From: flb@flb.optiplan.fi ("F.Baube x554") -Subject: Low-Pressure O2 Atmosphere -Date: 10 Nov 92 13:11:49 GMT -If our lunar atmosphere is pure O2, then every dust cloud -kicked up by a lunar buggy creates an explosion hazard. -It will have to be "diluted". One of the concerns of the Apollo program was that lunar materials might ignite in the oxygen atmosphere of the Lunar Module. Apparently it didn't happen. It could be that most of the materials are too thoroughly oxidized to be particularly flammable. The book I mentioned gives average soil (< 1 mm fraction) for seven Apollo sites, which generally show concentrations of the components to be consistent to within an order of magnitude (mostly closer than that.) Here's the composition for the Apollo 11 site: SiO2 (42.04%), TiO2 (7.48%), Al2O3 (13.92%), FeO (15.74%), MgO (7.90%), CaO (12.01%), Na2O (0.44%), K2O (0.14%), P2O5 (0.12%), MnO (0.21%), Cr2O3 (0.30%). (There are also tables for overall highland and maria composition.) Does anything in there sound like it would be flammable in the stated concentrations? -Can nitrogen be generated ? There's very little nitrogen there (0.19 ppm) - it would probably have to be imported. But I think that would be worthwhile.

More myths about oxygen. Normal oxygen partial pressure is about 150 mmHg (3 psi). A pure O2 atmosphere at 150 mmHg total pressure is no better or worse, physiologically speaking, than air at sea level. Nor is it more of a fire hazard. Oxidation proceeds at a rate proportional to the partial pressure. Oxygen, like many gases, has narcotic effects at very high pressures, such as in deep-sea diving. It can cause blindness in newborns (retrolental fibroplasia) at 1 atm. Otherwise, it's safe to breathe pure O2 at 1 atm, and patients in cardiac care units often do so for days and longer. I've done it many times, and it has absolutely no noticeable effects. -- Steve Jenkins jenkins@devvax.jpl.nasa.gov Caltech/Jet Propulsion Laboratory (818) 306-6438 ------------------------------ Date: Wed, 11 Nov 92 02:09:40 GMT From: "John P.

This could be sold at a rate to other countries also. Power produced on the lunar surface and beamed directly to earth would have a number of drawbacks: 1) You'd need a very tight beam, which you'd have to be able to aim. 2) Even if you manage to take care of 1), the energy would be available at any particular place on Earth only 12 hours out of the day, with efficiency of the microwave link going down toward the ends of the period. Furthermore, the time of day when the energy is available at any particular place on earth won't be the same from day to day. It will vary throughout the day over the course of a lunar month. 3) Any particular lunar installation will be inoperative for half of every lunar month, with decreasing efficiencies toward either end of the period in which it's operational. Now, you *COULD* alleviate the second problem by using geostationary relay satellites, and you could alleviate the third by having installations spread around the moon, using yet another relay station (at L4 or L5). However, we're now talking about a LOT of hardware. It would almost certainly make more sense to put the solar cells on the geosync satellites. -------------------------------------------------------------------------------- Carl J Lydick | INTERnet: CARL@SOL1.GPS.CALTECH.EDU | NSI/HEPnet: SOL1::CARL Disclaimer: Hey, I understand VAXen and VMS.

In orbit, it was still pure O2 at about 3.5psi. Even that is >a bit above the partial pressure of O2 at sea level (~ 3.08 psi) First off, it was Apollo 12, and not Apollo 1, that caught fire. The cause of the fire was indeed the overpressure of test of the O2. As it turned out, what killed the astronauts was not the fire, but the velcro inside the spacecraft. Although the velcro was fireproof for the low 3.5 psi, and up to 5psi, the overpressure tests of pure O2 made them quite flammable. Hell, at 16psi of oxygen, damn near anything will burn. In the words of Mike Gray, author of _Angle of Attack_, "Somehow, in the labyrinth of the organization charts, the people who tested the spacecraft materials for flammability were never connected to the people who knew that-- for a brief period at the beginning of the moon trip-- the astronauts would be bathed in high-pressure oxygen." The fire ignited the velcro under high-pressure, and the resultant toxic fumes killed the astronauts within seconds. -- John Mechalas "I'm not an actor, but mechalas@gn.ecn.purdue.edu I play one on TV."

November 10, 1992 (Phone: 202/358-1547) Mike Fluharty National Science Foundation, Washington, D.C (Phone: 202/357-9498) RELEASE: 92-200 FIRST STEPS TO MARS TAKEN BY SIMULATION IN ANTARCTICA Scientists from NASA and the National Science Foundation (NSF) are taking the first steps to Mars this winter in the most unearthly place on the planet -- Antarctica. NASA and NSF researchers are conducting several unique science and technology projects developed under a joint effort called the Antarctic Space Analog Program. The program uses the harsh, frigid conditions of the Antarctic continent to test technology and techniques for future missions to the moon and Mars. "Our current work stresses exploration by robots and tests of the equipment needed to support humans in a remote environment. We're also studying how humans interact with those technologies," said Dr. John D. Rummel, NASA Program Committee Co-Chairperson. "The U.S. Antarctic Program, under NSF management, is interested in testing NASA-developed technologies, such as telescience, which could help reduce the number of people who run our scientific experiments," said Dr. Carol A. Roberts, NSF Program Committee Co-Chairperson. "Also," she continued, "we are very much interested in preserving the pristine Antarctic environment through improved waste processing and energy production technologies." The Antarctic, known for its physical challenges, isolation and rugged terrain, is an excellent place to evaluate exploration technologies and human factor questions because scientists live and work under conditions similar to those that planetary explorers will encounter. "Telepresence" and Power From October through December, researchers are studying a permanently frozen Antarctic lake using "telepresence" technology developed at NASA's Ames Research Center, Mountain View, Calif. Telepresence lets an operator, wearing a video headset, see through cameras on a remotely- controlled robot. The researcher's head movements direct the camera's movements. In the project, a remotely operated "rover", connected to the surface by a cable, will descend into Lake Hoare to study the lake's life forms. The goal is to demonstrate the scientific use of telepresence while gaining further insight into the Mars environment that may have existed several billion years ago. The scientists' field camp is supported by an advanced solar power system that can be deployed easily in remote field locations. NASA's Lewis Research Center, Cleveland, developed the system. The NASA Office of Space Science and Applications and Office of Advanced Concepts and Technology and NSF's Division of Polar Programs jointly sponsor the expedition. "Dante" to Descend into Volcanic "Inferno" Later this season, NASA plans to send an eight-legged robot into the crater of Antarctica's Mount Erebus, the world's only easily-reached volcano with a permanent lava lake. The rover, appropriately dubbed "Dante," will photograph the crater, measure the temperature of the lava lake and sample the gases it releases. The Erebus project will test technology for future robotic explorers that could cross the rugged Martian landscape. It also will collect science data to help understand Earth's environment, since some scientists think that gases from volcanic eruptions may play a role in depleting Earth's ozone layer. Carnegie Mellon University, Pittsburgh, built Dante under a $2 million NASA grant. [NOTE: This rover test has been postponed to next year. Last week, Dante damaged four its legs during a test run and has been sent back to Carnegie Mellon for repairs. Ron Baalke ] Fresh Food for Future Explorers In another experiment, the NASA/NSF researchers are trying to produce fresh food and to a significant extent, recover water under controlled conditions at the South Pole. The Closed Ecological Life Support System Antarctic Analog Project addresses crop productivity, the effect of fresh food on humans' well-being and how the integrated system performs. Scientists believe that having fresh food during the long South Polar winter will be good for their physical and psychological well-being -- benefits that would apply to long-duration human space missions as well. The project's waste management system also will reduce the impact of humans on the pristine polar environment. In January, scientists will travel to the South Pole to evaluate the site and to analyze waste materials that will be recycled by the system. The program is managed by the Advanced Life Support Division at NASA's Ames Research Center and is co-sponsored by Ames' Life Sciences Division and the NSF Division of Polar Programs. - end - ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@kelvin.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |__ M/S 525-3684 Telos | Give people a second /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | chance, but not a third. |_____|/ |_|/ |_____|/ | ------------------------------ Date: Wed, 11 Nov 1992 01:33:35 GMT From: "John D.

Non-existant: A two-gas system would be enough trouble that no one is looking into it. As for 1 atm, it really isn't necessary: At 8.5 psi, you don't have problems with pre-breathing or the bends anymore. High pressures do, however, usually limit the mobility/flexability of a suit. The current (unfunded) goal is for a 8.5 psi "no pre-breath" pure-oxygen suit.

The dates are: Advanced Adult Camp Feb 18-21 Beginning Adult Camp Apr 23-25 Beginning Teen Camp Jun 7-14 Advanced Teen Camp Jun 18-25 The Astronomy Camps are run by Steward Observatory (Univ. of Arizona) as a non-profit educational outreach project. Attendees use the 40", 60", and 61" research telescopes of the Mt Lemmon and Mt Bigelow Observatories (north of Tucson) operated by NASA and Steward. A 16" Schmidt camera and numerous portable telescopes are also available. The Adult Camps are during weekends and consist of observing (using eyepieces, astrophotography with film and CCDs, and photometry, according to participant interest) and lectures, demonstrations, and discussions. Tours of research and engineering facilities, such as the spin-casting facilities of the Steward Observatory Mirror Lab, are also conducted. The Teen Camps (for ages 13 to 17) each last a week, four nights of which are spent observing. Activities include those of the Adult Camps plus tours of Kitt Peak facilities, science demonstrations, lectures (space program, archaeoastronomy, space art with Kim Poor, etc.) and other activities (model rockets, volleyball, orienteering in the mountains, etc.) For both Teens and Adults, the Advanced camps are for those who have previously attended a Beginning Camp or who have prior amateur astronomy experience. The Camps are run by Dr Donald McCarthy of Steward Observatory. Other Steward faculty and graduate students, as well as personnel of Flandrau Planetarium, participate as guest speakers and camp counselors.
