NASA News Release: 08-136 May 31, 2008

Space shuttle Discovery and a seven-member crew has launched from NASA’s Kennedy Space Center to deliver and install a Japanese laboratory on the International Space Station.

The mission, designated STS-124, is the second of three flights to launch components to complete the Japan Aerospace Exploration Agency’s Kibo laboratory.  Discovery is carrying Kibo’s tour bus-sized Japanese Pressurized Module, or JPM, which will be the station’s largest module.  The shuttle astronauts will work with the three-member station crew and ground teams around the world to install the JPM and Kibo’s robotic arm system.

Joining Kelly on Discovery’s 14-day flight are Pilot Ken Ham and Mission Specialists Karen Nyberg, Ron Garan, Mike Fossum, Greg Chamitoff and Japan Aerospace Exploration Agency astronaut Akihiko Hoshide.

Garan and Fossum will conduct three spacewalks during the mission.  Chamitoff will replace current station crew member Garrett Reisman, who has lived on the outpost since mid-March.  Chamitoff will return to Earth on Endeavour’s STS-126 mission, targeted for Nov. 10.

NASA is providing continuous television and Internet coverage of Discovery’s mission, which is the 123rd shuttle flight, the 35th for Discovery and the 26th shuttle mission to the station.

NASA Television features live mission events, daily mission status news conferences and 24-hour commentary.

JPL/NASA/University of Arizona News Release: 2008-090 May 30, 2008

Scientists have discovered what may be ice that was exposed when soil was blown away as NASA’s Phoenix spacecraft landed on Mars on Sunday May 25th.  The possible ice appears in an image the robotic arm camera took underneath the lander, near a footpad.

“We could very well be seeing rock, or we could be seeing exposed ice in the retrorocket blast zone,” said Ray Arvidson of Washington University , St. Louis , Mo., co-investigator for the robotic arm.  “We’ll test the two ideas by getting more data, including color data, from the robotic arm camera.  We think that if the hard features are ice, they will become brighter because atmospheric water vapor will collect as new frost on the ice.

Testing last night of a Phoenix instrument that bakes and sniffs samples to identify ingredients identified a possible short circuit.  The instrument is the Thermal and Evolved Gas Analyzer.  It includes a calorimeter that tracks how much heat is needed to melt or vaporize substances in a sample, plus a mass spectrometer to examine vapors driven off by the heat.  The Thursday, May 29, tests recorded electrical behavior consistent with an intermittent short circuit in the spectrometer portion.

“We have developed a strategy to gain a better understanding of this behavior, and we have identified workarounds for some of the possibilities,” said William Boynton of the University of Arizona , Tucson , lead scientist for the instrument.

The latest data from the Canadian Space Agency’s weather station shows another sunny day at the Phoenix landing site with temperatures holding at minus 30 degrees Celsius (minus 22 degrees Fahrenheit) as the sol’s high, and a low of minus 80 degrees Celsius (minus 112 degrees Fahrenheit).  The lidar instrument was activated for a 15-minute period just before noon local Mars time, and showed increasing dust in the atmosphere.

“This is the first time lidar technology has been used on the surface of another planet,” said the meteorological station’s chief engineer, Mike Daly, from MDA in Brampton , Canada .  “The team is elated that we are getting such interesting data about the dust dynamics in the atmosphere.”

“We have evaluated the performance of the spacecraft on the surface and found we’re ready to move forward.  While we are still investigating instrument performance such as the anomaly on TEGA [Thermal and Evolved Gas Analyzer], the spacecraft’s infrastructure has passed its tests and gets a clean bill of health,” said David Spencer of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., deputy project manager for Phoenix.

“We’re still in the process of checking out our instruments,” Phoenix project scientist Leslie Tamppari of JPL said. “The process is designed to be very flexible, to respond to discoveries and issues that come up every day. We’re in the process of taking images and getting color information that will help us understand soil properties. This will help us understand where best to first touch the soil and then where and how best to dig.”

The Phoenix mission is led by Peter Smith at the University of Arizona with project management at JPL and development partnership at Lockheed Martin, Denver . International contributions come from the Canadian Space Agency; the University of Neuchatel , Switzerland ; the universities of Copenhagen and Aarhus , Denmark ; Max Planck Institute, Germany ; and the Finnish Meteorological Institute.

JPL/NASA/University of Arizona News Release: 2008-083 for May 26, 2008

A telescopic camera in orbit around Mars caught a view of NASA’s Phoenix Mars Lander suspended from its parachute during the lander’s successful arrival at Mars Sunday evening, May 25th.

The image from the High Resolution Imaging Science Experiment (HiRISE) on NASA’s Mars Reconnaissance Orbiter marks the first time ever one spacecraft has photographed another one in the act of landing on Mars.

Meanwhile, scientists pored over initial images from Phoenix , the first ever taken from the surface of Mars’ polar regions.

“We can see cracks in the troughs that make us think the ice is still modifying the surface,” said Phoenix Principal Investigator Peter Smith of the University of Arizona , Tucson .

“I’m floored. I’m absolutely floored,” said Phoenix Project Manager Barry Goldstein of NASA’s Jet Propulsion Laboratory, Pasadena , Calif. A team analyzing what can be learned from the Phoenix descent through the Martian atmosphere will use the image to reconstruct events.

The Phoenix mission is led by Smith at the University of Arizona with project management at JPL and development partnership at Lockheed Martin, Denver.  International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

JPL manages the Mars Reconnaissance Orbiter mission for NASA. Lockheed Martin Space Systems, Denver , Colo. , is the prime contractor for the project and built the spacecraft. The University of Arizona operates the High Resolution Imaging Science Experiment camera, which was built by Ball Aerospace and Technology Corp., Boulder , Colo.

“Mars is literally pulling on our spacecraft, and at the same time it is pulling on our emotions,” Phoenix Principal Investigator Peter Smith, of the University of Arizona , Tucson , said early Sunday afternoon.

“We are excited at how close we are right now to beginning our study of a site where Martian water ice will be within our reach, after all these years of preparations. Our science mission begins as the spacecraft settles into its new home on Mars.”

It’s just a few hours until NASA’s Phoenix Mars Lander makes it’s landing attempt on the planet Mars. It’s headed for the Martian arctic, which is farther north than any other spacecraft has landed on the red planet. In fact, only five landings have been successful, out of the eleven previous attempts.

Shortly after the annual 500-mile race at the Indianapolis Motor Speedway, Phoenix will be approaching Mars at about 12,750 miles per hour. After it enters the top of the Martian atmosphere at that velocity, it must use superheated friction with the atmosphere, a strong parachute and a set of pulsing retrorockets to achieve a safe, three-legged standstill touchdown on the surface in just seven minutes. That’s the scariest seven minutes of the entire mission.

The earliest possible time when mission controllers could get confirmation from Phoenix indicating it has survived landing will be at 7:53 p.m. Eastern Time.

The landing site is expected to have ice-rich permafrost beneath the surface, but within reach of the lander’s eight-foot robotic arm. Phoenix is equipped to study the history of the water now frozen into the site’s permafrost, to check for carbon-containing chemicals that are essential ingredients for life, and to monitor polar-region weather on Mars from a surface perspective for the first time.

The Phoenix mission is led by the University of Arizona with project management at JPL and development partnership at Lockheed Martin. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

Space Shuttle Discovery’s next mission is scheduled for a May 31st launch. The STS-124 mission is the second of three flights to deliver components of the Japanese Aerospace Exploration Agency’s Kibo laboratory to the International Space Station.

With the increased pace of the shuttle program, it’s harder to keep up with their daily activities as it’s crews gear up to complete missions before the shuttle fleet is retired in 2010. However, Space Shuttle News can be found at nasa.gov/mission_pages/shuttle/main/

NASA News:

The crew of the International Space Station will take part in a news conference on Tuesday April 15th at 10:00 am, CDT. The 30-minute conference will be broadcast live on NASA TV.

Members of the 17th crew of the station, Expedition 17 Commander Sergei Volkov and Flight Engineer Oleg Kononenko, docked their Soyuz spacecraft to the station early Thursday. With them is South Korean spaceflight participant So-yeon Yi, who will stay on the complex for nine days under a commercial agreement with the Russian Federal Space Agency.

Space Shuttle Endeavour landed at Florida’s Kennedy Space Center Wednesday night after a remarkable 16 day mission. The crew of STS-123 accomplished a record five spacewalks, during which they constructed the Dextre Robotics System and installed the first module of the Kibo Japanese Experiment Logistics Module.

The International Space Station will now receive the new Jules Verne Automated Transfer Vehicle, or ATV, from Europe. The ATV is scheduled to dock with the station on April 3rd.

The wonderful author and visionary, Arthur C. Clarke, who has written so many thought provoking books, has passed away at the ripe old age of 90.  My favorite, and probably his most famous is “2001: A Space Odyssey.”  I’ve always been a big fan of sci-fi, and Clarke’s books were right at the top of my list, along with H.G. Wells.

Clarke has one of those truly amazing biographies, which includes predicting a global network of communication satellites, writing an astounding amount of books and scientific articles, being knighted as Sir Arthur C. Clarke by Britain’s Queen Elizabeth in 1998 for his work with science fiction, working as an underwater explorer, and finally as a recluse in Sri Lanka.

Can you imagine some of Clarke’s “future visions” of making contact with intelligent life from other planets by the year 2030, or discovering the secret of immortality by 2090?
