NASA is ready to send six little satellites into space，but it will take about three years to reach space.Those satellites can be able to help scientists keep a closer eye on heavy storms，and they develop a task called TROPICS to send the satellites to space.Importantly，if NASA does it successfully，the satellites will help us make a big difference in watching coming heavy storms.
   At the moment，NASA's weather satellites can only check in on a storm every four to six hours."So we're missing a lot of what's happening in the storm，"Bill Blackwell，the leader of the TROPICS team，at the MIT Lincoln Laboratory，said.However，the new set of six satellites will allow researchers to check in on a storm about every hour.
   After sending the satellites，scientists will put them in a perfect place to watch the areas where most storms are born，from the center of America to the south of Australia.Each satellite is just under 0.3 meters long with a powerful machine that's about as big as a cup of coffee.The small machine can measure heat and light produced from O₂ and H₂O in the air，then the data will be sent to the Earth.
   It will bring many advantages.First，the data measured by the TROPICS satellites will help researchers study better how a storm grows.They can even build a 3 D model of a storm developing with the help of satellites.Also，scientists will know when the storm will come and get people to safety as soon as possible.Just like last year，hundreds of people died because of Storm Ida coming overnight.It won't happen anymore.
   That makes it all more important to have more eyes over the sky."The TROPICS team is super excited to send these satellites and get them running，"Bill Blackwell said in NASA statement.
