Milwaukee, WI, joined a long list of cities that have utilized drones for a synchronized light show and holiday entertainment. Over 200 drones were filmed and broadcast to viewers in their homes for the Milwaukee Holiday Lights Festival. Check out this impressive light show here to gear up for the holidays!
Three autonomous ocean drones will sail the Gulf Stream during six harsh winter months collecting climate data. Previously, strong winter currents and fierce storms have prevented high-quality data collection, forcing reliance on models yielding uncertain results. With these drones, scientists now have access to these regions.
Saildrone uncrewed surface vehicles (USVs) feature wind-powered propulsion technology, solar-powered meteorological and oceanographic sensors, and long-range autonomous sailing capabilities. The USVs assist in mapping remote oceans and collecting climate data, such as collecting live footage inside a category four hurricane and circumventing Antarctica.
“We collected as many ocean CO2 measurements in the Gulf Stream for the month of February as had ever been recorded in the entire history of oceanography,” said Jaime Palter, a carbon scientist and a co-principal investigator of the mission.
These drones provide access to remote, hazardous regions and rapidly increase the rate of data collection. Scientists will be able to improve forecasting models countries rely on to lower carbon emissions and better understand global weather patterns and climate.
NASA launched the first planetary defensive rocket. The rocket aims to test the ability to strike asteroids and deflect them off course before they cause any damage to Earth. Successful results from these tests could lead to reliable protection of the world in the future.
The rocket has a DART the size of a vending machine. It is released into space while the lower section safely returns to Earth. The DART is being tested using smaller asteroids that are far from Earth. The team aims to knock asteroids off course at 15,000 miles per hour (24,000 kph). They expect to shorten the orbital track by 10 minutes but will accept 73 seconds, given it is millions of miles away.
"It's going to deflect its path around the larger asteroid, so we're demonstrating asteroid deflection in this double asteroid system," says Nancy Chabot, the mission coordination lead.
It is rare for asteroids to impact Earth. However, developing this system will keep the world protected against potential catastrophic events.
