first Imager full-disk infrared image of the Earth

Operational Environmental Satellite – GOES-15 – took its first Imager full-disk infrared image of the Earth on April 26 starting at 1730 UTC (1:30 p.m. EDT). Each of the five Imager spectral bands are shown. There is one visible band and four infrared bands (shortwave window, water vapor, longwave window and a CO2 sensitive band)

The Sounder is another instrument on GOES-15 which also took Infrared images of the Earth. The Sounder is designed to provide data from which atmospheric temperature and moisture profiles, surface and cloud-top temperatures, and ozone distribution can be deduced by mathematical analysis.

GOES-15 also provides visible images of Earth. On April 6, GOES-15 captured its first visible image of Earth.

Expedition 23 Works on New Crew Quarters, Maintenance


Aboard the orbiting International Space Station, the Expedition 23 crew spent Monday outfitting its newest crew quarters facility and performing maintenance.

Commander Oleg Kotov and Flight Engineer Mikhail Kornienko worked to outfit the newest crew quarters, which was delivered to the station aboard space shuttle Discovery during the STS-131 mission. The modular crew quarters facilities provide each of the station’s occupants with their own “personal space” that resembles a booth. In their quarters they can stow their personal belongings, rest and spend their recreational time. Each unit provides the crew member with visual, light and acoustic isolation, as well as laptop connectivity.

Flight Engineer Tracy Caldwell Dyson spent time collecting and analyzing water samples from the orbital outpost’s water processing system.

Flight Engineer Soichi Noguchi conducted maintenance on the cooling loops for the U.S. spacesuits in the Quest airlock in preparation for spacewalks to be performed by the STS-132 crew, set to arrive at the station aboard space shuttle Atlantis next month.

Over the weekend, the crew completed the annual maintenance work on the Treadmill Vibration Isolation System and completed the relocation of the COLBERT treadmill into the Tranquility node.

The ISS Progress 35 undocked from the Pirs Docking Compartment Thursday after being loaded with trash and other unneeded gear and equipment. The Progress will be used for scientific experiments until it is deorbited and burned up in the Earth's atmosphere this week.

The ISS Progress 37 cargo ship was transported to its launch pad at the Baikonur Cosmodrome in Kazakhstan for final preparations for launch on Wednesday. Progress 37 will dock to the station Saturday, bringing 1,918 pounds of propellant, 110 pounds of oxygen and air, 220 pounds of water and 3,031 pounds of spare parts and experiment hardware.

Robotics Work Station Relocation and Station Reboost for Crew

Expedition 23 Commander and Russian cosmonaut Oleg Kotov downlinked live video and audio of the treadmill while it was operating inside the Zvezda service module. Kotov identified unusual sounds and motion coming from the treadmill and was working with ground controllers to see if there was a problem. Ground controllers determined everything was nominal but continued to analyze the issue.

With American and Russian spacecraft coming and going to the station over the next two months, the docked ISS Progress 36 supply craft fired its engines on Friday afternoon to raise the orbiting laboratory to the proper altitude.

The ISS Progress 35 undocked from the Pirs Docking Compartment on Thursday after being loaded with trash and other unneeded gear and equipment. The Progress will be used for scientific experiments until it is deorbited and burned up in the Earth's atmosphere next week.

Pirs will host the new ISS Progress 37 when it docks on Saturday, May 1. ISS Progress 37 will bring to the station 1,918 pounds of propellant, 110 pounds of oxygen and air, 220 pounds of water and 3,031 pounds of spare parts and experiment hardware.

Space shuttle Atlantis will arrive at the International Space Station in May for the 12-day STS-132 mission. On June 2, Expedition 23 crew members Kotov, T.J. Creamer and Noguchi will return home in the Soyuz TMA-17. Expedition 24 crew members Fyodor Yurchikhin, Doug Wheelock and Shannon Walker will arrive in the Soyuz TMA-19 to begin their stay on June 18.

Crew Prepares for ISS Progress 35 Undocking

The Expedition 23 crew members aboard the International Space Station were busy Wednesday preparing for the undocking of the ISS Progress 35 supply ship. They also performed routine station maintenance and worked with science experiments.

The unmanned Progress cargo resupply vehicle is scheduled to undock at 12:32 p.m. EDT Thursday from the Pirs docking compartment. Filled with trash and station discarded items, the cargo craft will deorbit and burn up in the Earth's atmosphere.

ISS Progress 35 arrived at the station Oct. 17 after launching Oct. 14 from the Baikonur Cosmodrome in Kazakhstan.

Commander Oleg Kotov and Flight Engineers Alexander Skvortsov and Mikhail Kornienko tested the Russian telerobotically operated rendezvous system, TORU, which they can use to monitor the Progress undocking or take control of the process in the unlikely event that difficulties arise with the automated Kurs system.

The Russians also performed maintenance on the Treadmill Vibration Isolation System (TVIS). The TVIS is an important part of the exercise regimen aboard the station. Each crew member exercises for 2.5 hours daily to stave off the effects of long-term exposure to weightlessness.

Flight Engineers T.J. Creamer and Tracy Caldwell Dyson worked on a variety of research, including the Evaluation of Maximal Oxygen Uptake and Submaximal Estimates of VO2max Before, During, and After Long Duration International Space Station Missions (VO2max) experiment, which looks at the working capacity of humans in microgravity, and the Transgenic Arabidopsis Gene Expression System (TAGES) experiment, which uses plants specially fitted with genes that make them glow so that scientists can monitor how they grow in the space environment.

Meanwhile, Flight Engineer Soichi Noguchi inspected hatch seals around the station. He also worked with the Reaction Self Test experiment that helps monitor the daily effects of living in space.

Space shuttle Discovery descended to a smooth landing Tuesday at the Kennedy Space Center in Florida to conclude the STS-131 mission that brought 7.6 tons of supplies and equipment to the station, including a new crew sleeping quarters, a new ammonia tank, a new gyroscope and four experiment racks.

Space Shuttle Discovery Undocks from Station

The Expedition 23 crew and the STS-131 crew of space shuttle Discovery parted company Saturday at 8:52 a.m., wrapping up a mission that brought 7.6 tons of supplies and equipment to the International Space Station, including a new crew sleeping quarters, a new ammonia tank, a new gyroscope and four experiment racks.

Discovery arrived at the station on April 7.

The mission was the final roundtrip to the station for the 21-foot-long, 15-foot-diameter Multi-Purpose Logistics Module Leonardo. It will return to Earth in Discovery’s cargo bay with about 2.5 tons from the station. Once back on Earth, the module will be reconfigured with increased shielding on the outside for the STS-133 mission in September when it will be left on the station as a permanent module.

Artist's conception of the GOES-13

"Just in time for the 2010 hurricane season, NOAA will have one of its newest, technologically advanced satellites closely tracking these storms – from when they develop to when they dissipate," said Mary Kicza, assistant administrator of the National Oceanic and Atmospheric Administration's (NOAA) Satellite and Information Service in Silver Spring, Md.

NASA's GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md., procures and manages the development and launch of the GOES series of satellites for NOAA on a cost-reimbursable basis. NASA's GOES Project also creates some of the GOES satellite images and GOES satellite imagery animations. NOAA manages the operational environmental satellite program and establishes requirements, provides all funding and distributes environmental satellite data for the United States.

"It is exciting to think that we are now putting into service the best satellites this country has to offer," said Andre' Dress, GOES N-P NASA Deputy Project Manager, at Goddard. "We are really looking forward to see the increase in performance over the older satellites and the improvements in weather prediction."

Crews Remove Leonardo from Station

After dealing with a balky set of bolt controllers, the combined crew of space shuttle Discovery and the International Space Station removed the Leonardo Multi-Purpose Logistics Module from its station port Thursday.

The crew then used the station’s robotic arm to maneuver the module into position above Discovery’s payload bay. Leonardo will remain in this “low hover” position overnight, and the crew will spend about an hour and a half finishing the job of using Canadarm2 to latch it in the shuttle’s cargo bay on Friday.

Leonardo brought about six tons of material to the station and will return to Earth in Discovery’s cargo bay with about 2.5 tons from the station.

This is the final roundtrip to the station for the 21-foot-long, 15-foot-diameter Leonardo. Once back on Earth, the module will be reconfigured with increased shielding on the outside for the STS-133 mission in September when it will be left on the station as a permanent module.
