CAPE CANAVERAL, Fla. -- The first of NASA's three next-generation
Tracking and Data Relay Satellites (TDRS), known as TDRS-K, launched
at 8:48 p.m. EST Wednesday from Cape Canaveral Air Force Station in
Florida.
"TDRS-K bolsters our network of satellites that provides essential
communications to support space exploration," said Badri Younes,
deputy associate administrator for Space Communications and
Navigation at NASA Headquarters in Washington. "It will improve the
overall health and longevity of our system."
The TDRS system provides tracking, telemetry, command and
high-bandwidth data return services for numerous science and human
exploration missions orbiting Earth. These include the International
Space Station and NASA's Hubble Space Telescope.
"With this launch, NASA has begun the replenishment of our aging space
network," said Jeffrey Gramling, TDRS project manager. "This addition
to our current fleet of seven will provide even greater capabilities
to a network that has become key to enabling many of NASA's
scientific discoveries."
TDRS-K was lifted into orbit aboard a United Launch Alliance Atlas V
rocket from Space Launch Complex-41. After a three-month test phase,
NASA will accept the spacecraft for additional evaluation before
putting the satellite into service.
The TDRS-K spacecraft includes several modifications from older
satellites in the TDRS system, including redesigned
telecommunications payload electronics and a high-performance solar
panel designed for more spacecraft power to meet growing S-band
requirements. Another significant design change, the return to
ground-based processing of data, will allow the system to service
more customers with evolving communication requirements.
The next TDRS spacecraft, TDRS-L, is scheduled for launch in 2014.
TDRS-M's manufacturing process will be completed in 2015.
NASA's Space Communications and Navigation Program, part of the Human
Exploration and Operations Mission Directorate at the agency's
Headquarters in Washington, is responsible for the space network. The
TDRS Project Office at NASA's Goddard Space Flight Center in
Greenbelt, Md., manages the TDRS development program. Launch services
were provided by United Launch Alliance. NASA's Launch Services
Program at the Kennedy Space Center was responsible for acquisition
of launch services.

Leaks Found in Earth's Protective Magnetic Field
By Andrea Thompson
Senior Writer
posted: 16 December 2008
03:20 pm ET
Scientists have found two large leaks in Earth's magnetosphere, the region around our planet that shields us from severe solar storms.
The leaks are defying many of scientists' previous ideas on how the interaction between Earth's magnetosphere and solar wind occurs: The leaks are in an unexpected location, let in solar particles in faster than expected and the whole interaction works in a manner that is completely the opposite of what scientists had thought.
The findings have implications for how solar storms affect the our planet. Serious storms, which involved charged particles spewing from the sun, can disable satellites and even disrupt power grids on Earth.
The new observations "overturn the way that we understand how the sun's magnetic field interacts with the Earth's magnetic field," said David Sibeck of NASA's Goddard Space Flight Center in Greenbelt, Md., during a press conference today at the annual meeting of the American Geophysical Union in San Francisco.
The bottom line: When the next peak of solar activity comes, in about 4 years, electrical systems on Earth and satellites in space may be more vulnerable.
How it works
Earth's magnetic field carves out a cavity in the sun's onrushing field. The Earth's magnetosphere is thus "buffeted like a wind sock in gale force winds, fluttering back and forth in the" solar wind, Sibeck explained.
Both the sun's magnetic field and the Earth's magnetic field can be oriented northward or southward (Earth's magnetic field is often described as a giant bar magnet in space). The sun's magnetic field shifts its orientation frequently, sometimes becoming aligned with the Earth, sometime becoming anti-aligned.
Scientists had thought that more solar particles entered Earth's magnetosphere when the sun's field was oriented southward (anti-aligned to the Earth's), but the opposite turned out to be the case, the new research shows.
The work was sponsored by NASA and the National Science Foundation and based on observations by NASA's THEMIS (Time History of Events and Macroscale Interactions during Substorms) satellite.
How many and where
Essentially, the Earth's magnetic shield is at its strongest when scientists had thought it would be at its weakest.
When the fields aren't aligned, "the shield is up and very few particles come in," said physicist Jimmy Raeder of the University of New Hampshire in Durham.
Conversely, when the fields are aligned, it creates "a huge breach, and there's lots and lots of particles coming in," Raeder added, at the news conference.
As it orbited Earth, THEMIS's five spacecraft were able to estimate the thickness of the band of solar particles coming when the fields were aligned — it turned out to be about 20 times the number that got in when the fields were anti-aligned.
THEMIS was able to make these measurements as it moved through the band, with two spacecraft on different borders of the band; the band turned out to be one Earth radius thick, or about 4,000 miles (6,437 kilometers). Measurements of the thickness taken later showed that the band was also rapidly growing.
"So this really changes our understanding of solar wind-magnetosphere coupling," said physicist Marit Oieroset of the University of California, Berkeley, also at the press conference.
And while the interaction of anti-aligned particles occurs at Earth's equator, those of aligned particles occur at higher latitudes both north and south of the equator. The interaction is "appending blobs of plasma onto the Earth's magnetic field," which is an easy way to get the solar particles in, said Sibeck, a THEMIS project scientist.
Next solar cycle
This finding not only has implications for scientists' understanding of the interaction between the sun and Earth's magnetosphere, but for predicting the effects to Earth during the next peak in the solar cycle.
The Sun operates on an 11-year cycle, alternating between active and quiet periods. We are currently in a quiet period, with few sunspots on the sun's surface and fewer solar flares, though the next cycle of activity has begun. It is expected to peak around 2012, bringing lots of sunspots, flares and coronal mass ejections (CMEs). CMEs can interact with the Earth's magnetosphere, causing problems for satellites, communications, and power grids.
This upcoming active period now looks like it will be more intense than the previous one, which peaked around 2006, some scientists think. The reason is the changes in the sun's alignment.
During the last peak, solar fields hitting the Earth were first anti-aligned then aligned. Anti-aligned fields can energize particles, but in this case, the energy came before the particles themselves, which doesn't create much of a fuss in terms of geomagnetic storms and disruptions.
But the next cycle will see aligned, then anti-aligned fields, in theory amplifying the effects of the storms as they hit.
Raeder likens the difference to igniting a gas stove one of two ways: In the first way, the gas is turned on and the stove is lit and you get a flame. In the other way, you let the gas run for awhile, so that when you add the gas you get a much bigger boom.
"It should be that we're

Pablo Reyes, from the EVEX team at University of Illinois in Urbana-Champaign, demonstrates part of the IRIS radar. IRIS is a specialized instrument custom-built for EVEX, which will provide high time resolution pictures of the "sunset layer" that indicates turbulence and strong winds overhead. Such information combined with the data collected by EVEX will help create a robust picture of what’s happening in the ionosphere during the times when it disrupts radio signals.

A NASA-funded sounding rocket mission will launch from an atoll in the Pacific this spring. The mission will help scientists better understand and predict the electrical storms in Earth's upper atmosphere that can negatively affect satellite communication and global positioning signals.
The mission, called EVEX, for the Equatorial Vortex Experiment, will launch into a crucial layer of charged particles surrounding our planet. Called the ionosphere, this layer serves as the medium through which high frequency radio waves – such as those sent down to the ground by global positioning system (GPS) satellites or, indeed, any satellite communicating with Earth – travel. The ionosphere begins about 60 miles above the ground and is filled with electrons and ions, alongside the more familiar extension of our electrically neutral atmosphere. Governed by Earth’s magnetic field, high-altitude winds, and incoming material and energy from the sun, the ionosphere can be calm in certain places or times of day, and quite turbulent at others.
EVEX will launch two rockets for a twelve-minute journey through the equatorial ionosphere above the South Pacific. This area of the ionosphere is known for calm days and tempestuous evenings, times when the ionosphere becomes rippled like a funhouse mirror, disturbing radio signals, and introducing GPS errors of a half mile or more. The two rockets will measure events in two separate regions of the ionosphere to see how they work together to drive the ionosphere from placid and smooth to violently disturbed. Such information could ultimately lead to the ability to accurately forecast this important aspect of space weather.
The launch window for EVEX is from April 27 to May 10. The team will decide when to fly based on conditions in the ionosphere on any given night.

Check this out from NASA -- Yes, but could you get to work on time if the Moon looked like this? As the photographer was preparing to drive to work, refraction, reflection, and even diffraction of moonlight from millions of falling ice crystals turned the familiar icon of our Moon into a menagerie of other-worldly halos and arcs. The featured scene was captured with three combined exposures two weeks ago on a cold winter morning in Manitoba, Canada. The colorful rings are a corona caused by quantum diffraction by small drops of water or ice near the direction of the Moon. Outside of that, a 22-degree halo was created by moonlight refracting through six-sided cylindrical ice crystals. To the sides are moon dogs, caused by light refracting through thin, flat, six-sided ice platelets as they flittered toward the ground. Visible at the top and bottom of the 22-degree halo are upper and lower tangent arcs, created by moonlight refracting through nearly horizontal hexagonal ice cylinders. A few minutes later, from a field just off the road to work, the halo and arcs had disappeared, the sky had returned to normal -- with the exception of a single faint moon dog. (ift.tt/2SWMxvJ)

What kind of cloud is this? A type of arcus cloud called a roll cloud. These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. Unlike a similar shelf cloud, a roll cloud is completely detached from their parent cumulonimbus cloud. Pictured above, a roll cloud extends far into the distance in 2009 January above Las Olas Beach in Maldonado, Uruguay. via NASA ift.tt/232pBYp

Fans of planet Earth probably recognize its highest mountain, the Himalayan Mount Everest, on the left in this 3-panel skyscape of The World at Night. Shrouded in cloud Everest's peak is at 8,848 meters (29,029 feet) elevation above sea level. In the middle panel, stars trail above volcanic Mauna Kea forming part of the island of Hawaii. Festooned with astronomical observatories, its summit lies a mere 4,168 meters above sea level. Still, measured from its base starting below the ocean's surface, Mauna Kea is over 10,000 meters tall, making it Earth's tallest mountain from base to summit. At right, beneath the arc of the Milky Way is the Andean mountain Chimborazo in Ecuador. The highest equatorial mountain, the Chimborazo volcano's peak elevation is 6,268 meters above sea level. But rotating planet Earth is a flattened sphere (oblate spheroid) in shape, its equatorial diameter greater than its diameter measured pole to pole. Sitting nearly on top of Earth's greatest equatorial bulge, Chimborazo's peak is the farthest point on the planet's surface from the center, over 2,000 meters farther from the center of the Earth than Everest's peak. That makes Chimborazo's summit the place on Earth's surface closest to the stars. via NASA ift.tt/1XOFjnl

Check this out from NASA -- How far away is spiral galaxy NGC 4921? It's surpringly important to know. Although presently estimated to be about 300 million light years distant, a more precise determination could be coupled with its known recession speed to help humanity better calibrate the expansion rate of the entire visible universe. Toward this goal, several images were taken by the Hubble Space Telescope in order to help identify key stellar distance markers known as Cepheid variable stars. Since NGC 4921 is a member of the Coma Cluster of Galaxies, refining its distance would also allow a better distance determination to one of the largest nearby clusters in the local universe. The magnificent spiral NGC 4921 has been informally dubbed anemic because of its low rate of star formation and low surface brightness. Visible in the featured image are, from the center, a bright nucleus, a bright central bar, a prominent ring of dark dust, blue clusters of recently formed stars, several smaller companion galaxies, unrelated galaxies in the far distant universe, and unrelated stars in our Milky Way Galaxy.

Questions also will be taken from other participating NASA locations.
Shuttle Atlantis' 11-day flight, designated STS-125, is targeted for launch Oct. 8 and will include five spacewalks to refurbish and upgrade the telescope with state-of-the-art science instruments. Replacing failed hardware on Hubble will extend the telescope's life into the next decade.
U.S. news media planning to attend the briefings at Johnson must contact the newsroom there at 281-483-5111 by Sept. 2 to arrange for credentials. All reporters who are foreign nationals must contact the newsroom by Aug. 8.
On Sept. 9, Atlantis' seven astronauts will be available for round-robin interviews at Johnson. Reporters planning to participate in-person or by phone must contact Gayle Frere at 281-483-8645 by Sept. 2 to reserve an interview opportunity.
Scott Altman will command Atlantis' crew, which includes Pilot Gregory C. Johnson, and Mission Specialists Andrew Feustel, Michael Good, John Grunsfeld, Megan McArthur and Mike Massimino. The spacewalkers are Good, Grunsfeld, Feustel and Massimino. McArthur is the flight engineer and lead for robotic arm operations.
Along with the briefings to preview the Hubble servicing mission at Johnson, media will have an opportunity during the afternoon of Sept. 8 to review new equipment being developed for NASA's Constellation Program. Constellation is building America's next human spacecraft, which will fly astronauts to low Earth orbit, the moon and beyond. During the review, media will see items that include concepts of a new spacesuit, a pressurized rover vehicle for astronauts, and a mockup of the Orion crew capsule.
The schedule (all times are CDT) includes:
Monday, Sept. 8
7 a.m. - Video B-Roll Feed
8 a.m. - NASA Overview Briefing (from Goddard)
9 a.m. - Shuttle Program Overview Briefing (from Johnson)

The goal of this group is to encourage people to re-interpret and remix the great photo libarary NASA has released into the public domain. Please take this photo Remix It, make a Mashup by combing this photos with other images or textures and reinvent it into a new piece of art. Go ahead give it a try, its fun! Then post your artwork to the group pool. To view some of the best images in the group you can view our stream on flickr river. If your up for a challenge we host remix competitions every month on our discussion forum.
Neil Armstrong trained for the Apollo 11 mission at NASA Langley's Lunar Landing Research Facility on equipment that cancelled all but one-sixth of Earth's gravitational force. Armstrong offered perhaps the greatest tribute to the importance of his training when asked what it was like to land on the moon, replying, "Like Langley." via NASA go.nasa.gov/2t8BKyY

A NASA-funded sounding rocket mission will launch from an atoll in the Pacific this spring. The mission will help scientists better understand and predict the electrical storms in Earth's upper atmosphere that can negatively affect satellite communication and global positioning signals.
The mission, called EVEX, for the Equatorial Vortex Experiment, will launch into a crucial layer of charged particles surrounding our planet. Called the ionosphere, this layer serves as the medium through which high frequency radio waves – such as those sent down to the ground by global positioning system (GPS) satellites or, indeed, any satellite communicating with Earth – travel. The ionosphere begins about 60 miles above the ground and is filled with electrons and ions, alongside the more familiar extension of our electrically neutral atmosphere. Governed by Earth’s magnetic field, high-altitude winds, and incoming material and energy from the sun, the ionosphere can be calm in certain places or times of day, and quite turbulent at others.
EVEX will launch two rockets for a twelve-minute journey through the equatorial ionosphere above the South Pacific. This area of the ionosphere is known for calm days and tempestuous evenings, times when the ionosphere becomes rippled like a funhouse mirror, disturbing radio signals, and introducing GPS errors of a half mile or more. The two rockets will measure events in two separate regions of the ionosphere to see how they work together to drive the ionosphere from placid and smooth to violently disturbed. Such information could ultimately lead to the ability to accurately forecast this important aspect of space weather.
The launch window for EVEX is from April 27 to May 10. The team will decide when to fly based on conditions in the ionosphere on any given night.
