The bioavailibility of lead in six soils was estimated using the three models and the results were compared with the results of a bioavailability study conducted on juvenile swine. The behavior of lead in the gastrointestinal tract of swine was comparable to that in children. Both the Unified BARGE model and the Tiny-TIM model show the same pattern as the results of the animal experiments. However, the Tiny-TIM values underestimate the true bioavailability. The IVD model is only suitable after a correction for calcium content of the soil. An alternative, relatively simple method is to estimate the bioavailable lead in a soil using an extraction with diluted nitric acid. This method can be used as a screening method to estimate the bioavailability of lead in the soil.

STORY WRITTEN FOR & USED WITH PERMISSIONPosted: May 27, 2004; Updated at 8:30 p.m. EDT with burn completionFor the first time in nearly five years, the Cassini spacecraft's main engine system ignited this evening for a critical course adjustment that will serve as a dress rehearsal of sorts for Saturn orbit insertion July 1. An artist's concept of Cassini. Credit: NASA/JPLThe computer-initiated rocket firing, known as trajectory correction maneuver 20, began on time at 7:47:31 p.m. EDT and lasted some five minutes and 56 seconds. Assessment of Cassini's slightly altered trajectory, along with analysis of spacecraft telemetry, will not be available until later. But a spokeswoman for the Jet Propulsion Laboratory said "everything appeared to have gone well," based on subtle changes in the radio signal coming from the spacecraft.TCM-20 was designed to change Cassini's velocity by about 78 mph, setting up a flyby of the moon Phoebe June 11. It also marked one of the final corrections before a 96-minute-long July 1 rocket firing required to put the spacecraft in orbit around Saturn.TCM-20 was relatively minor as such things go, but it marked the first time the craft's propulsion system was fully exercised since a major 87-minute "deep space maneuver" in December 1998.No one at NASA's Jet Propulsion Laboratory in Pasadena, Calif., expected any problems and a six-minute burn by the 100-pound-thrust main engine is "pretty small by SOI or DSM standards," Cassini propulsion engineer Todd Barber, a veteran of the Galileo and Mars Exploration Rover missions, said last week. "That's the bad news. The good news is it's totally regulated, so we'll be able to verify that all the valves work and that the helium's flowing properly."Helium provides the pressure needed to push propellant and oxidizer into the engine's combustion chamber. Cassini's main helium regulator began leaking shortly after launch in 1997, but by using a downstream valve to isolate the system between firings, engineers are able to manage the leakage. Those same procedures were used for TCM-20 and will be used again for Saturn orbit insertion and a final major orbit adjustment burn in late August.Unlike the lengthy, make-or-break SOI burn, TCM-20 could have been carried out in "blow-down" mode using residual tank pressure, Barber said, which would not have required use of the helium regulator."But it's ostensibly there not only to target Phoebe for our June 11 flyby, the major purpose of this burn is a propulsion system checkout," he said. "It gives us a real warm fuzzy going into SOI."It currently takes radio signals from Earth, traveling through space at 186,000 miles per second, more than one hour and 20 minutes to reach Cassini. As a result, tonight's rocket firing, like all such burns, was initiated, controlled and shut down by the spacecraft's on-board computer.The burn "is a good practice run, no question about that," said Cassini project manager Bob Mitchell. "But the science from this is kind of a big deal, too."Discovered in 1898, Phoebe measures just 137 miles across, orbits Saturn at a distance of nine million miles and circles the planet in the opposite direction from its other moons. Because of that, and the tilt of its orbit, scientists believe Phoebe may be a captured asteroid or a Kuiper belt object left over from the birth of the solar system.Voyager 2 imaged Phoebe in 1981 from a distance of about 1.4 million miles. Tonight's rocket firing will allow Cassini to pass within just 1,250 miles of the enigmatic moon."Voyager imaged Phoebe a long time ago and got some images that were quite distant, quite blurred and didn't really provide a whole lot of information," Mitchell said. "And now, we're going to get down to, I think, something like 18-meters-per-pixel resolution. And Phoebe has enough gravity that while it really doesn't do anything of any significance to the trajectory, it does tweak it enough that you can feel it."So the radio science guys ... will get a mass estimate from the flyby. From that and images that tell you the size, they get the density. So there's quite a bit of science coming back from this."Cassini was launched Oct. 15, 1997, from the Cape Canaveral Air Force Station. Using two gravity assist flybys of Venus, one of Earth and a final boost from Jupiter, Cassini has taken seven years to reach its target. Carrying 12 sophisticated instruments and a European probe with a half-dozen instruments of its own that will descend through the atmosphere of the moon Titan, the $3.4 billion Cassini is the most complex deep space mission ever attempted.The 96.4-minute Saturn orbit insertion rocket firing, which will change Cassini's velocity by slightly more than 1,400 mph, is scheduled to begin at 10:35:42 p.m. EDT on June 30. It should end around 12:11 a.m. July 1, kicking off a planned four-year orbital tour of the ringed planet and its many moons.A detailed Cassini mission overview, based on interviews with senior scientists, managers and spacecraft engineers, will be posted here next week.Ares 1-X PatchThe official embroidered patch for the Ares 1-X rocket test flight, is available for purchase.Apollo CollageThis beautiful one piece set features the Apollo program emblem surrounded by the individual mission logos.Expedition 21The official embroidered patch for the International Space Station Expedition 21 crew is now available from our stores.Hubble PatchThe official embroidered patch for mission STS-125, the space shuttle's last planned service call to the Hubble Space Telescope, is available for purchase. | | | | 2014 Spaceflight Now Inc.Cassini spacecraft spies Saturn's moon Iapetus CASSINI PHOTO RELEASEPosted: August 22, 2004 The dark material that coats one hemisphere of Saturn's moon Iapetus is very dark, as these two processed views of the same image demonstrate. Credit: NASA/JPL/University of ArizonaDownload larger image version The image on the left has been cleaned of cosmic rays and magnified; in this otherwise un-enhanced view, only a small part of the moon's surface, at the bottom, is visible because it is part of the bright side of Iapetus. (Only the right hand side of Iapetus is illuminated by sunlight.) The same image, shown on the right, has been contrast-enhanced to make visible the part of the illuminated side of Iapetus that is coated with dark material. The image was taken in visible light, with the Cassini spacecraft narrow angle camera from a distance of 2.9 million kilometers (1.8 million miles) from Iapetus, and at a Sun-Iapetus-spacecraft, or phase angle of 89 degrees. The image scale is 17 kilometers (11 miles) per pixel. The image has been magnified by a factor of four to aid visibility.

STORY WRITTEN FOR & USED WITH PERMISSIONPosted: July 12, 2014 After a string of delays cause by stormy weather, conflicts with other flights and an engine test failure, Orbital Sciences Corp. is readying an Antares rocket for launch Sunday on a voyage to deliver 1.7 tons of cargo and supplies to the International Space Station, the company's second commercial resupply mission. Photo of the Antares rocket on launch pad 0A at Wallops Flight Facility. Credit: NASA/Bill IngallsWith forecasters predicting a 90 percent chance of acceptable weather, the two-stage 133-foot-tall Antares was scheduled for launch from the Mid-Atlantic Regional Spaceport at NASA's Wallops Island Flight Facility on the Virginia coast at 12:52 p.m. EDT (GMT-4) Sunday, the opening of a five-minute launch window."We're very proud and pleased to be back here at Wallops again, conducting this operation leading up to the launch of Antares," said Frank Culbertson, a former shuttle commander who serves as Orbital's vice president and general manager of advanced programs. "We're real proud to be part of the team that is keeping the station flying and providing the crew with the cargo and research they need." Orbital engineers had hoped to launch the rocket and its company-developed Cygnus cargo ship Friday, but the flight was delayed through the weekend by severe weather that interrupted ground processing.Assuming an on-time launch Sunday, the uncrewed Cygnus capsule will reach the space station early Wednesday, pulling up to within about 30 feet and then standing by while the lab's robot arm locks on to pull it in for berthing at the Earth-facing port of the forward Harmony module.The spacecraft is loaded with 3,669 pounds of crew supplies, including food for the lab's crew, spare parts and other station hardware, science equipment, spacewalk components and computer hardware.The science equipment includes a variety of student experiments, supplies for NASA's Human Research Facility, igniters for the station's combustion test facility and a Japanese experiment that will study Marangoni convection, a type of heat transfer between solids and liquids that could lead to improvements in microgravity life support systems.Also on board: 28 small satellites -- nanosats -- built by Planet Labs of San Francisco, part of a growing fleet of "Dove" spacecraft being tested in a commercial venture to continuously photograph the Earth. Four other nanosats also are on board, including one built by NASA to test techniques for returning small experiment samples to the ground. The Orb-2 mission patch. Credit: Orbital Sciences Corp.The Cygnus spacecraft will remain attached to the station for about a month. After it is unloaded and re-packed with trash and no-longer-needed equipment, the cargo ship will be released to burn up in Earth's atmosphere. Before re-entry, Orbital flight controllers plan to test new rendezvous equipment and procedures intended to allow Cygnus capsules to remain aloft for extended periods, enabling research after the spacecraft leave the station.This will be Orbital's second operational station resupply mission -- Orb-2 -- under a $1.9 billion commercial contract with NASA calling for eight flights through 2016 to deliver some 40,000 pounds of supplies and equipment. SpaceX holds a similar $1.6 billion contract covering 12 resupply flights to deliver 44,000 pounds of cargo.SpaceX has carried out three resupply missions to date with a fourth on tap in September and a fifth in December. Orbital plans its third resupply flight in October with two more on tap next year.This week's Antares launching originally was planned for May, but the flight was delayed to early June, at NASA's request, because of conflicts with other station traffic. Then, on May 22, a first-stage engine being test fired for an Antares/Cygnus resupply flight next year suffered a catastrophic failure 30 seconds into a planned 54-second burn. The engine was destroyed, and the planned June flight was put on hold pending an investigation.The Antares first stage is powered by two AJ26 engines supplied by Aerojet Rocketdyne. The engines originally were developed for the Soviet Union's ill-fated N-1 moon rocket. When that program was cancelled after multiple launch failures, the engines were stockpiled and in the 1990s, Aerojet bought about 40 of the powerplants and modified them for use aboard U.S. rockets.The May 22 test failure "obviously sparked a very thorough investigation led by Aerojet Rocketdyne, our engine supplier, supported fully by Orbital with a lot of help by NASA," said Mike Pinkston, Orbital's Antares program manager. "That was a lengthy process and the primary source of the delay from the early part of June to where we are today."The failure investigation is not yet complete and no details have been provided to the media. But the engines scheduled for use Sunday were cleared for flight after internal boroscope inspections and a review of data collected during their own test firings earlier."We saw what we needed to see with that and with the fact that these engines successfully passed the same acceptance process, not only here in the United States, but also twice after original manufacture in Russia," Pinkston said. "They've got a lot of test time on them. We've got a lot of confidence that the two engines on Orb-2 are ready to go."Final Shuttle Mission PatchFree shipping to U.S. addresses!The crew emblem for the final space shuttle mission is now available in our store.

The Cygnus spacecraft is released from the International Space Station. Credit: NASA TVThe automated solar-powered spaceship disengaged from the space station's robotic arm at 1141 GMT (6:41 a.m. EST) as the duo sailed 260 miles over the South Atlantic Ocean east of Argentina.Astronauts Mike Hopkins and Koichi Wakata monitored the activities from inside the space station's windowed cupola module. Hopkins was assigned the job of detaching the robot arm from Cygnus.Moments later, astronauts inside the space station sent commands for the Cygnus spacecraft to fire thrusters and fly away from the complex. It cleared the space station's "keep out" sphere, an imaginary safety zone around the outpost, a few minutes after separating from the robot arm.The Cygnus vehicle's pressurized logistics module is packed with bags of trash and unnecessary gear loaded by the space station's six-person crew. Like cargo vehicles supplied by Europe, Japan and Russia, the Cygnus spacecraft is designed to burn up during re-entry, disposing of garbage over a remote stretch of the South Pacific Ocean.Re-entry between New Zealand and South America is scheduled for around 1820 GMT (1:20 p.m. EST) Wednesday after a pair of braking maneuvers to slow the Cygnus spacecraft's velocity and lower its orbit.The last day of the Cygnus mission will be controlled from Orbital Sciences' headquarters in Dulles, Va.The Cygnus spacecraft is on the first of eight operationally cargo delivery flights under a $1.9 billion commercial resupply contract between Orbital Sciences and NASA. The space agency has a similar deal with SpaceX for a dozen missions worth $1.6 billion.The mission delivered nearly 2,800 pounds of supplies to the space station when it arrived Jan. 12, three days after launching from Wallops Island, Va., aboard an Antares rocket.The deliveries included an ant colony for students to observe how the ants behave in space, an experiment in drug-resistant bacteria, and investigations into how liquids slosh inside containers in microgravity and the behavior of fires in space.The scientific complement of the Cygnus spacecraft's cargo load amounted to nearly 1,000 pounds, the biggest delivery of experiments to the space station by one of the two U.S. commercial logistics vehicles.Orbital Sciences achieved a Cygnus demonstration mission to the space station last year before proceeding into the contracted flights.SpaceX and Orbital Sciences developed their resupply freighters and launch vehicles with public and private funding through a public-private partnership with NASA, which turned to the commercial sector to haul experiments and supplies to the space station after the retirement of the space shuttle.SpaceX plans a launch of its Falcon 9 rocket and Dragon spaceship from Cape Canaveral to the space station March 16. Orbital's next cargo flight is due to launch around May 1 aboard an Antares rocket from Virginia.Follow Stephen Clark on Twitter: .STS-134 PatchFree shipping to U.S. addresses!The final planned flight of space shuttle Endeavour is symbolized in the official embroidered crew patch for STS-134.
