Tropical Storm Cristobal captured in astronaut, satellite imagery


Photos of now-Tropical Depression Cristobal taken by a NASA astronaut and a satellite show the powerful storm tearing through the Gulf Coast region and making its way north across the United States.

Astronaut Chris Cassidy on the International Space Station captured four views of Cristobal, then still a tropical storm, on Monday (June 8) as it appeared from 260 miles (420 kilometers) above Earth. 

"Best of luck to all of the folks in the gulf coast region who are about to deal with the weather from Tropical Storm #Cristobal," Cassidy wrote on Twitter.

On Tuesday (June 9), NASA released images from the Aqua satellite showing the depression moving north toward the Great Lakes region. The satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) picked up the strongest regions of the storm using infrared images. Infrared data shows which parts of the storm are coldest; these regions are also the most powerful because they have thunderstorms that reach the highest in Earth's atmosphere, NASA said.

Early on Tuesday, MODIS data suggested that the strongest storms were "northeast and north of the elongated center over western Missouri, Iowa and Illinois," NASA said, and the instrument measured storm cloud-top temperatures as cold as minus 63 degrees Fahrenheit (nearly minus 57 degrees Celsius).

Cristobal, however, is quickly evolving and forecasts will change rapidly in the next few days. As of late afternoon Tuesday, the National Weather Service's Weather Prediction Center says Cristobal is moving across Missouri, with heavy rainfall expected in the middle and upper Mississippi Valley, as well as in the western Great Lakes region.

You may soon be able to ride to the edge of space from Alaska in a Balloon Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere. Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune,  The Anchorage Daily News  reported on Sunday. The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium. Each passenger could pay an estimated $125,000 for a six-hour journey. Mark Lester, CEO of Alaska Aerospace Corp., said the high-altitude rides will be available from Kodiak in a few years and will support A

Committee recommends review of planetary protection policies

Committee recommends review of planetary protection policies WASHINGTON — The NASA Advisory Council has recommended that NASA review its existing planetary protection guidelines to balance the needs of science and exploration, an effort that could set the stage for a similar revision at the international level. The council, during a two-day meeting at NASA Headquarters Dec. 10–11, adopted a recommendation calling on NASA to establish an interdisciplinary committee of experts to review the agency’s current requirements for preventing contamination of other worlds by NASA spacecraft as well as any contamination of the Earth by materials brought back from those worlds. “NASA should establish a multidisciplinary task force of experts from industry, the scientific community, and relevant government agencies, to develop U.S. policies that properly balance the legitimate need to protect against the harmful contamination of the Earth or other celestial bodies with the scientific, social, and e

Surprise! There's more water on Jupiter than anyone thought

Surprise! There's more water on Jupiter than anyone thought Jupiter  appears to have more water than anyone expected. Newly released data from  NASA's Juno probe shows that water may make up about 0.25% of the molecules in the atmosphere over Jupiter's equator. While that doesn't sound like much, the calculation is based on a prevalence of water's components, hydrogen and oxygen, three times more than at the sun. The new measurements Juno obtained are much higher than a previous mission suggested. The surprise result has scientists delving deep again into results from  NASA's Galileo mission to Jupiter , which obtained drier results in 1995 when engineers deliberately threw the spacecraft into Jupiter's atmosphere. (Galileo was low on fuel and NASA didn't want to take the chance, even if it was a slight one, of the spacecraft accidentally crashing on a potentially habitable icy moon.) Reconciling the results from Galileo and Juno is key for sc
