Pasadena, CA – You can’t predict the outcome of a marathon from the runners’ times in the first few miles. You’ve got to see the whole race. Global climate change is like that: You can’t understand it if all you have is a few years of data from a few locations. That’s one reason that a fourth-generation satellite launching this summer is something to get excited about.
Jason-3, a mission led by the National Oceanic and Atmospheric Administration that is currently scheduled to launch on July 22nd, is the latest in a series of U.S.-European satellite missions that have been measuring the height of the ocean surface for 23 years.
Chikungunya Virus Disease Spread by Bites
Nashville, TN – The Tennessee Department of Health is reminding vacation and business travelers about the importance of protecting themselves from mosquitoes that may transmit chikungunya virus and other mosquito-borne illnesses like dengue.
The first confirmed case of chikungunya virus disease in Tennessee occurred in 2014; since then 42 additional cases have been documented, all involving travel outside the state.
Washington, D.C. – NASA’s Orion spacecraft continues on the agency’s journey to Mars as engineers analyze data from the spacecraft’s December flight test and make progress developing and building the spacecraft for its first mission atop NASA Space Launch System (SLS) heavy-lift rocket. On future missions, Orion will send astronauts to an asteroid and onward toward the Red Planet.
At machine houses across the country, elements of the primary structure for the next Orion to fly in space are coming together. Avionics components are being built and simulators for the ESA (European Space Agency)-built service module that will house the spacecraft’s propulsion and solar arrays are being delivered.

Greenbelt, MD – Severe weather in the form of tornadoes is not something people expect on Christmas week but a storm system on December 23rd brought tornadoes to Mississippi, Georgia and Louisiana. As the storm moved, NASA’s RapidScat captured data on winds while NOAA’s GOES satellite tracked the movement of the system.
NASA’s RapidScat instrument flies aboard the International Space Station and captured a look at some of the high winds from the storms that brought severe weather to the U.S. Gulf Coast on December 23rd. In addition, an animation of images from NOAA’s GOES-East satellite showed the movement of those storms and other weather systems from Canada to South America from December 21st to 24th.

Cape Canaveral, FL – NASA marked a major milestone Friday on its journey to Mars as the Orion spacecraft completed its first voyage to space, traveling farther than any spacecraft designed for astronauts has been in more than 40 years.
“Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space on our Journey to Mars,” said NASA Administrator Charles Bolden. “The teams did a tremendous job putting Orion through its paces in the real environment it will endure as we push the boundary of human exploration in the coming years.”
Washington, D.C. – In the not-too-distant future, astronauts destined to be the first people to walk on Mars will leave Earth aboard an Orion spacecraft.
Carried aloft by the tremendous power of a Space Launch System rocket, our explorers will begin their Journey to Mars from NASA’s Kennedy Space Center in Florida, carrying the spirit of humanity with them to the Red Planet.
The first future human mission to Mars and those that follow will require the ingenuity and dedication of an entire generation. It’s a journey worth the risks.

Pasadena, CA – A new NASA mission that will boost global monitoring of ocean winds for improved weather forecasting and climate studies is among about 5,000 pounds (2,270 kilograms) of NASA science investigations and cargo now on their way to the International Space Station aboard SpaceX’s Dragon spacecraft.
The cargo ship launched on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida at 10:52pm PDT Saturday, September 20th (1:52am EDT Sunday, September 21st).

Pasadena, CA – The fourth SpaceX cargo mission to the International Space Station (ISS) under NASA’s Commercial Resupply Services contract, carrying the ISS-RapidScat scatterometer instrument designed and built by NASA’s Jet Propulsion Laboratory, Pasadena, California, is scheduled to launch Saturday, September 20th, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The one-day adjustment in the launch date was made to accommodate preparations of the SpaceX Falcon 9 rocket and was coordinated with the station’s partners and managers.

Laghman Province, Afghanistan – Forty-three years ago, U.S. Congress designated August 26th as Women’s Equality Day to commemorate granting women the right to vote.
When put into historical military context, the roles women have filled in their service to their country have gone under measureable change in the 239 year history of the U.S. Army — when women would help nurse the wounded and sick during the Revolutionary War.
Now, women make up approximately 15 percent of the active-duty Army and represent 95 percent of its’ career fields.

Pasadena, CA – Nitrogen and oxygen make up nearly 99 percent of Earth’s atmosphere. The remaining one percent is comprised of gases that — although present in small concentrations — can have a big impact on life on Earth.
Trace gases called greenhouse gases warm the surface, making it habitable for humans, plants and animals. But these greenhouse gases, as well as clouds and tiny particles called aerosols in the atmosphere, also play vital roles in Earth’s complex climate system.
