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

NASA to use commercial launch vehicle for Europa Clipper

NASA to use commercial launch vehicle for Europa Clipper NASA to use commercial launch vehicle for Europa Clipper WASHINGTON — NASA is no longer considering launching the Europa Clipper mission on the Space Launch System, deciding instead to launch the spacecraft on a commercial rocket it will procure in the next year. During a Feb. 10 presentation at a meeting of NASA’s Outer Planets Assessment Group (OPAG), leaders of the Europa Clipper project said the agency recently decided to consider only commercial launch vehicles for the mission, and no longer support a launch of the spacecraft on the SLS. “We now have clarity on the launch vehicle path and launch date,” Robert Pappalardo, project scientist for Europa Clipper at the Jet Propulsion Laboratory, said. That clarity came in the form of a Jan. 25 memo from NASA’s Planetary Missions Program Office to “immediately cease efforts to maintain SLS compatibility” and move forwa
