Let It Rain, Let It Rain, Let It Rain


Although Olympic focus has been trained on Rio, the gringa would like to take the dear reader back in time and to the other side of the globe to the 2008 Beijing Olympics. When China was preparing to host this historical event, pollution was high on the list of problems to solve. Although everyone is probably familiar with the tactic of temporary bans on driving & factory operations as drastic measures to help reduce smog. What many may not be aware of is China’s ambitious plans to control the weather, a $30 million dollar plan that they are still working on today. A plan to shoot into the heavens special “bullets” filled with salt and other minerals. What in the world are those crazy Chinese scientists up to? Apparently, nothing new! They’re just trying to make it rain.

Officially called “weather modification”, China helped clear their smog-filled skies during the Olympic games by making it rain, rain, rain. They are not alone in being rainmakers. Fifty-two other countries have developed their own rainmaking strategies. Ten of these countries joining the rainmaking team only five years ago. Rainmaking countries include: Canada, United States, Mexico, Cuba, Brazil, Chile, Argentina, Australia, India, Senegal, South Africa, Russia and the list goes on. You can see the map created by the World Meteorological Organization to see who all is in on the rainmaking game.

The gringa is rather ashamed to admit that as for the United States, the origins of its weather modification program is not as noble as China’s. For the U.S., it all started with Operation Popeye which was a top secret program that weaponized weather during the Vietnam War. Although I’m sure the scientists who worked for General Electric had noble intentions, they probably had no idea that the U.S. government was going to take their technology and rain down silver iodide on the poor Vietnamese people.

But I digress. Back to China. In addition to creating rain to saturate polluted air and get rid of smog, they also wanted to prevent rain from spoiling events taking place in the stadium that was dubbed the “Bird’s Nest”. To achieve this amazing god-like feat, the Chinese implemented a 3 stage weather modification strategy:

  1. Officials tracked weather patterns with satellites, planes, radar and supercomputer.
  2. 2 aircraft, 20 rocket launcher & artillery sites sprayed silver iodide and dry ice into remote cloud systems that might approach the stadium so they would dump their rain before arrival.
  3. Nearby cloud systems filled with rain were seeded with chemicals that shrink the water droplets thus ensuring that the clouds would have time to pass over the Bird’s Nest without dropping their rain.

Now was all of this really necessary? The Beijing Olympics were held in August which is a high precipitation season for China so, yes, the gringa supposes that it was necessary. Consequently, China’s success in being a master rainmaker or rainstaller has resulted in China being the world leader in the weather modification sciences. They have more than 1,500 professionals devoted to all things necessary in controlling the weather: scientists, pilots, flight crews. Also proudly serving in the program are tens of thousands of peasant farmers who are more than happy to help their government blast away a cloud when crops have been inundated or have clouds seeded during times of drought. Peasants are on call to operate more than 7,000 aircraft guns and almost 5,000 rocket launchers when called to report to rainmaking duty.

The gringa is not too sure what to make of all this. For the most part I am the type to believe that the less we interfere with nature, the better. However, considering how bad mankind has screwed things up where climate change is concerned, it may just be that Mother Nature could use a few rainmakers. So, I say to the Chinese:

Let it rain. Let it rain. Let it rain.

Amazing Grace and the Conveyor Belt


Is there a way to stem the tide of sea level rise due to climate change? I mean, if we can’t build a seawall around the coast of every continent and island, what other option is there other than an eventual mass human migration inland? Well, NASA thinks there very well may be a solution.

The Earth may be saving herself. Climate change researchers have been collecting data from NASA satellites to determine where all this extra liquid water from melted ice sheets and glaciers is ending up. It seems the Earth has absorbed over three trillion tons of water (that’s about the equivalent of what’s in Lake Huron) that are replenishing depleted lakes and underground aquifers. Now, this is great news but not a permanent fix. Researchers estimate this temporary band-aid will slow sea level rise by about twenty percent. Earth is buying us Earthlings some more time to get our you-know-what together and fix this mess we have created.

So, how does this “band-aid” work? The Earth’s regular water budget is provided by annual amounts of water evaporated from the oceans. This becomes precipitation that returns to the Earth through rainfall or snow. It then recycles back into the oceans as runoff or through rivers. As mankind’s use of groundwater has dramatically increased, the Earth has become quite thirsty as reservoirs are depleted. It has become a sponge, compensating for this unprecedented loss by absorbing what is melting from ice sheets and glaciers. This has served to curb rising sea levels despite the fact that glaciers and ice sheets continue to melt.

Now scientists are scrambling to recalculate future models and adjust previous projections of sea level rise as a result of the Earth’s warming oceans. So, although sea levels are still expected to rise, Earthlings have a little bit more time to solve the problems that will cause. But, once the Earth has slated her thirst, all that meltwater will then become a problem.

NASA is using a twin satellite system, GRACE (Gravity Recovery and Climate Experiment), to measure how much water is being stored within the Earth. Since scuba divers can’t delve into these underground reservoirs, just what kind of digital dipstick is being used? The satellites use gravity to measure liquid. The gringa scratches her head and says, “Um, what? A gravity yardstick? How does that work?”

As the twin satellites orbit the Earth, they measure the distance between themselves. Their measurements are so accurate and precise, they can get as close as a strand of human hair. Amazing! But, I digress. GRACE then transmits the data to Earthling researchers who use the information to measure any gravitational change in the Earth that is the result of any change Earth’s water distribution.

By using this method, scientists have measured how much water has been stored within Earth’s continents as a result of ice sheet and glacier melt. This is the first study of its kind. And, according to NASA’s mission to use technology to safeguard the future of Earth and the lives of Earthlings, the agency has shared this knowledge with other scientific communities around the world.

And GRACE is proving her mettle in other areas of climate change data as well. The satellites are tracking circulation and current patterns within the Atlantic Ocean. The typical current pattern of the Gulf Stream carries warm, tropical water northward to Greenland. By the time it arrives at its northern destination, the water has cooled significantly. Colder water is denser so the water that originated from the tropics, and was riding at the surface. has sunk as deep as two miles within the ocean by the time it gets to Greenland. The colder, heavier, bottom water is then dragged back South.

In this way the waters of the Atlantic Ocean are consistently agitated, cooled, oxygenated and nutritionally refreshed. Oceanographers call this pattern the Atlantic Meridional Overturning Circulation (AMOC). However, the gringa prefers the common name, the “Conveyor Belt” of the Atlantic.

The Atlantic’s “Conveyor Belt” effect is like an air conditioner for the world’s oceans. It is critical to modulating the temperature of the Earth. Data collected from GRACE has revealed that the “Conveyor Belt” is slowing down. Researchers are uncertain if this is directly caused by climate change or if other factors are at play.

GRACE is going to help answer these questions. One way is by measuring gravity data from the bottom of the Atlantic Ocean. Changes in the ocean’s currents will result in pressure changes that GRACE can detect with gravitational measurements.

And GRACE is also contributing to the development of practical solutions that can be implemented right now, helping the people of Brazil. 2015 was the worst year in over three decades for drought in Brazil.

Hydrologists were able to use data collected from GRACE to calculate that in a three year period Brazil lost about fifteen trillion gallons of water each year. Water levels of aquifers and rivers were also analyzed.

Brazil is heavily dependent on the country’s rivers to provide water for their people, electricity production and for critical agriculture. The data provided by GRACE enables the Brazilian government to create models that will simulate future expected droughts. This makes it possible for the nation to plan effectively, monitor their water resources responsibly and continue to provide for the water needs of over 200 million Brazilians.

And those are just some of the facts about “Amazing GRACE”.

Allow Me To Introduce You To JAXA


Who is JAXA? JAXA is the Japan Aerospace Exploration Agency and they have been very busy. In 2010 JAXA was disappointed when their orbiter “Akatsuki”, which, in  English, means “dawn”, failed in its mission to orbit Venus. However, JAXA is not one to give up. The agency kept at it for five years and finally, in December, accomplished its mission.

Now that Akatsuki is orbiting Venus its cameras are transmitting a steady stream of images. One orbit cycle takes about thirteen and one-half Earth days. JAXA is tweaking its orbit path to eventually get its orbit cycle to nine Earth days. That will result in Akatsuki being closer to Venus which will improve the clarity of the images it sends back to JAXA.

Venus is a hot, volcanic planet that is about the same size as Earth. And, when I say hot, the gringa means hot enough to melt lead. Akatsuki will gather data on the weather and atmosphere of this steamy planet. Scientists are interested in the volcanoes.

JAXA operates all missions with the purpose to help create a safe society that can utilize space. The agency seeks to be a leader in technology and have technology used wisely for the benefit of society. The Japanese believe that as humans evolve, happiness should increase. JAXA is inspired to overcome the difficulties facing mankind. They intend to act responsibly to meet the expectations society has for the work the Agency performs. The slogan JAXA operates under is “Explore to Realize”.

JAXA desires to contribute to the well being of all people on Earth through their research and development. They believe this can be achieved by improving quality of life, providing safety and security, developing sustainable methods for living, and expanding the knowledge of all peoples.

JAXA was established in October of 2003. The following Spring the agency successfully performed its first series of flight tests for their Stratosphere Stationary Platform. Since their first successful test flights, JAXA has continued to perform successfully. Just a few of their many accomplishments throughout the years:

  • July, 2005, the agency launched “Suzaku”, an X-ray astronomy satellite.
  • July through August of 2005 Japanese Astronaut Souichi Noguchi joined the NASA Space Shuttle “Discovery” mission.
  • December, 2005, JAXA made history with the first EVER optical inter-satellite communication between Optical Inter-orbit Communications Engineering (OICETS) and the Advanced Relay and Technology Mission “ARTEMIS” of the European Space Agency (ESA)
  • 2006-2007, successfully launched eight different space vehicles
  • March, 2008, Astronaut Takao Doi served aboard NASA Space Shuttle “Endeavor” on mission to attach Experiment Logistics Module-Pressurized Section (ELM-PS) of JAXA’s Experiment Module “Kibo” to the International Space Station (ISS)
  • June, 2008, Astronaut Akihiko Hoshide served aboard NASA Space Shuttle “Discovery” on mission to attach Pressurized Module (PM) and Remote Manipulator System of JAXA’s Experiment Module “Kibo” to the ISS.
  • July, 2009, Astronaut Koichi Wakata attached Exposed Facility of JAXA’s Experiment Module “Kibo” to ISS. First Japanese Astronaut to complete a long-stay mission and returned home aboard NASA Space Shuttle “Endeavour”
  • December, 2009, Astronaut Souichi Noguchi served aboard Russian Soyuz spacecraft on mission to ISS, completed long-stay mission, returning to Earth June, 2010
  • June, 2011, Astronaut Satoshi Furukawa served aboard Russian Soyuz spacecraft on mission to ISS and returned to Earth November, 2011
  • July, 2012, Astronaut Akihiko Hoshide served aboard Russian Soyuz spacecraft on mission to ISS, returning to Earth November, 2012
  • November, 2013, Astronaut Wakata served aboard Russian Soyuz spacecraft on mission to ISS. March, 2014, Astronaut Wakata became first Asian commander of ISS. Returned to Earth May, 2014

JAXA has big plans for 2016. It expects to launch the Mercury Magnetosphere Orbiter (MMO) after it successfully completes a round of tests performed by the European Space Agency (ESA). It will launch from the Guiana Space Center in French Guiana.

It is also committed to being an active world partner in resolving the many issues humanity must resolve that are related to climate change. JAXA will use the ALOS-2 satellite to monitor and collect data related to deforestation. All data will be available to everyone worldwide through open access on the Internet.

JAXA aims to develop a tracking system for tropical forests. JAXA will be joined in its efforts by the Japan International Cooperation Agency (JICA) and many private corporations. By constantly monitoring worldwide forest loss, the agency hopes that this initiative will lead to successful conservation solutions. A public access website should be up and running by March, 2017 and will be updated every six weeks with the latest findings.

Goals are to restrain illegal logging and conserve forests that are critical to help reduce the effects of climate change. During 2009-2012 Brazil was cooperating with monitoring efforts. Over 2,000 incidents were revealed and action was taken that helped reduce the destruction of forests by forty percent. It is clear that this effort and mission JAXA is undertaking is a significant contribution to the future security of humanity by helping to minimize the effects of climate change.

With agencies like JAXA looking out for the interests of people all over the world, the gringa is confident that this place we all call home has a future where there is great hope. The international cooperation of so many space agencies is an inspiration that we can become a global community where our differences are not obstacles, but, rather, strengths. Because the gringa thinks the world would be a very boring place if we were all alike.
