NASA asked people from around the globe to upload a selfie on Earth Day on social media so that a mosaic of the images with the globe could be created and posted on GigaPan at: http://www.gigapan.com/gigapans/155294

This spectacular image was built using 36,422 photos that were tagged #globalsefie in five humongous social media platforms around April 22, 2014. Here, people from more than 100 countries are all organized in a high quality rendering that people can zoom in and out of to see the selfies large or small.

The International Space Station will have a new lifeboat for approximately seven months. The lifeboat spacecraft is not necessarily wished to be called into service but in the event that people need to be evacuated off of the International Space Station, this “next generation” American spacecraft will come to rescue.

Right now, in the place of this next generation American spacecraft, the lifeboat function is served by a pair of Russian Soyuz spacecraft which hold three people each. The Soyuz lifeboat is pictured here:

This means that there can be six people working on a station at a time. With the next generation spacecraft, there is the ability to offer another four to seven seats so more people would be available for research duties according to NASA. This section explained the difference between the Soyuz spacecraft and the next generation American spacecraft that will soon be used. The new lifeboat looks like this:

Next, we look into engineering specifications and some of the conditions that lifeboats are designed to face.

In a recent article by NASA, their engineers revel the two capabilities that a spacecraft must perform to be called a life boat. They are: “First, the spacecraft needs to provide a shelter for astronauts in case of a problem on the station. Second, the ship has to be able to quickly get all its systems operating and detach from the station for a potential return to Earth.” In addition to these two requirements, the spacecraft also needs to run on the little amount of power that is dedicated for a docked crew spacecraft (the amount of power is about the amount of electricity a refrigerator uses). Let’s look at engineering’s relative that is, design.

When it comes to spacecraft design for the lifeboat feature, the challenges include a few things. First, it is ideal for the lifeboat to be powered off when not in use, but the deputy manager of CCP’s Spacecraft Office explained that this isn’t currently the case because air needs to be circulated since air doesn’t automatically circulate in microgravity the way it does on Earth. Another thing that designers need to look out for is that the spacecraft needs to be protected from things outside the spacecraft like micrometeoroids and should be able to survive an occasional hit, yet the armor cannot be too heavy to launch.

The new lifeboat is much anticipated because of the increased amount of people that it can hold. The “extra seats” compared to the Soyuz lifeboat which is currently used will most likely be used for researchers. In addition, the design and engineering challenges and specifications are extraordinary. We highly recommend viewing the NASA website for more information at: http://www.nasa.gov/

A newly released NASA satellite image taken from space shows the extent of California’s worst drought since record-keeping started in 1885 and potentially the region’s driest period in 500 years. The data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites vividly displays green areas that are supposed to be white with winter snow cover and brown areas that are supposed to be green with plant growth this time of year.

Green Halo - New NASA Satellite Image Shows California DroughtThe evergreen vegetation near the Sierra Nevada mountain range is usually covered with snow in a normal year. Most of the rest of the state — from the San Joaquin Valley to San Francisco to Los Angeles and beyond shows areas suffering from drought stress or left fallow because of lack of water to grow crop seeds.

“If you showed me this image without the date, I would say, ‘This is California in early fall after a long, hot summer, before the fall and winter rains and snows arrived,’” said Bill Patzert, a climate scientist at NASA’s Jet Propulsion Laboratory. “This is no California winter postcard.”

While recent rainfall and snowfall have brought temporary relief to parts of the state, it is not enough to mitigate the worst effects of the drought that is now in its third year. David Miskus of the NOAA Climate Prediction Center wrote that “even though this storm was welcome, the central Sierra still needs 3 to 4 more copious storms to bring this wet season close to average. Unfortunately, little to no precipitation fell on southern California and the Southwest.”

On a recent visit to California to tour the damage, President Obama pledged $183 million in federal aid and blamed the drought on climate change, saying “we’re going to have to stop looking at these disasters as something to wait for. We’re going to have to start looking at these disasters as something to prepare for.” The president added that “we have to be clear. A changing climate means that weather-related disasters like droughts, wildfires, storms, floods, are potentially going to be costlier and they’re going to be harsher.”

Just as a trunk full of luggage affects your gas mileage on a road trip, the amount of supplies on a spacecraft determines how far and efficiently a spacecraft can travel. In order to reduce the payload needed on missions to Mars or Green Halo NASA Oxygen Mars Moon Roverthe moon, NASA will conduct experiments designed to test “in-situ resource utilization” or (IRSU) strategies. These demonstrations will take advantage of indigenous resources to make water on the moon, and oxygen on Mars.

NASA will be launching two IRSU projects in the near future. The first is dubbed “Resource Prospector” where a rover will be sent to the moon equipped with tools to look for hydrogen and scan for water vapor. The mission is set for 2018, and researchers hope that their work will secure water so that the vital and heavy liquid doesn’t have to be carried along the entire trajectory of a mission.

The second IRSU will to hitch a ride on NASA’s next rover to Mars in 2020. The technology has yet to be selected, but will be responsible for grabbing CO2 from the atmosphere, screening out dust, and prepare the steps to convert the gas into oxygen. If both of these small-scale demonstrations are successful, NASA hopes to progress towards larger operations that will eventually make way for a manned mission to Mars.

Past projects have floated the idea of sending bacteria to the Red Planet in to construct “biobricks” for construction out of the planet’s dusty terrain. As the agency continues to make strides towards altering the landscape and atmosphere, it could be possible that some day soon the human race will see its first interplanetary colony.
