First Operational CMV-22B Osprey delivered to the U.S. Navy

Posted by in category: climatology

The U.S. Navy’s first CMV-22B Osprey for operational use arrived at Naval Air Station North Island, June 22. The tilt-rotor aircraft configured for Carrier Onboard Delivery (COD) missions is replacing the C-2A Greyhound.
=====================
The aircraft is assigned to the “Titans” of Fleet Logistics
Multi-Mission Squadron VRM 30, the Navy’s first CMV-22B squadron. VRM-30
was established in 2018 to begin the U…S Navy’s transition from the
C-2A Greyhound to the CMV-22B Osprey.

The CMV-22B is designed to carry up to 6,000 pounds of cargo and/or
personnel and operate up to a range of 1,150 nautical miles. One of the
reasons the Navy selected the V-22 airframe to serve in the COD role is
because of its ability to carry the F135 engine power module used by the
F-35C Lightning II Joint Strike Fighter.

Posted by in categories: climatology, nuclear energy

The National Weather Service in Melbourne has issued a severe thunderstorm warning for southeastern St. Lucie County and northeastern Martin County until 10 p.m.

At 9:18 p.m., a severe thunderstorm was located 7 miles north of Indiantown, moving northeast at 15 mph.

Locations impacted include Port Saint Lucie, Walton, Stuart, Palm City and Saint Lucie Nuclear Power Plant.

Weather looks OK for next SpaceX Starlink launch from Cape Canaveral

Posted by in categories: climatology, internet, satellites

The weather forecast appears to be trending slightly toward favorable conditions for the Space Coast’s next launch from Kennedy Space Center.

If schedules hold, a SpaceX Falcon 9 rocket will likely encounter 60% “go” conditions for its 5:22 p.m. Tuesday liftoff from pad 39A, the Space Force’s 45th Weather Squadron said Saturday. The 230-foot rocket will carry about 60 Starlink satellites for the company’s tenth internet constellation mission.

Showers and thunderstorms are expected Tuesday but should move mostly inland just before the launch time.

Follow the road to launch for our next mission to the Red Planet, the Mars 2020 Perseverance rover

Posted by in categories: alien life, climatology, robotics/AI

Administrator Jim Bridenstine, leadership and a panel of scientists and engineers will preview the upcoming mission at 2 p.m. EDT on Wednesday, June 17. Submit your questions during the briefing using #AskNASA!

Perseverance is a robotic scientist that will search for signs of past microbial life on Mars and characterize the planet’s climate and geology. It will also collect rock and soil samples for future return to Earth and pave the way for human exploration of the Red Planet. The mission is scheduled to launch from Space Launch Complex 41 at NASA’s Kennedy Space Center in Florida at 9:15 a.m. EDT July 20. It will land at Mars’ Jezero Crater on Feb. 18, 2021. #CountdownToMars

Tropical Storm Cristobal advances toward US Gulf Coast

Posted by in category: climatology

NEW ORLEANS (AP) — A re-energized Tropical Storm Cristobal advanced toward the U.S. Gulf Coast on Saturday, spawning a tornado in Florida and bringing the heavy rains that already caused flooding and mudslides in Mexico and Central America.

After weakening to a tropical depression while moving over land in Mexico’s Gulf coast, Cristobal headed back into the southern Gulf of Mexico from the Yucatan Peninsula on Friday and powered back up into a tropical storm. Forecasters said it would arrive on U.S. soil late Sunday but was not expected to grow into a hurricane.

The National Hurricane Center in Miami said the storm was expected to slowly strengthen until making landfall Sunday night along the U.S. Gulf Coast.

New biosensor visualizes stress in living plant cells in real time

Posted by in categories: biological, climatology

Plant biologists have long sought a deeper understanding of foundational processes involving kinases, enzymes that catalyze key biological activities in proteins. Analyzing the processes underlying kinases in plants takes on greater urgency in today’s environment increasingly altered by climate warming.

Certain “SnRK2” kinases (sucrose-non-fermenting-1-related protein -2s) are essential since they are known to be activated in response to , triggering the protective closure of small pores on leaf surfaces known as stoma. These pores allow carbon dioxide to enter leaves, but also lose more than 90 percent of their water by evaporation through them. Pore opening and closing functions help optimize growth and drought tolerance in response to changes in the environment.

Now, plant biologists at the University of California San Diego have developed a new nanosensor that allows researchers to monitor SnRK2 protein kinase activity in live plant cells. The SnRK2 activity sensor, or “SNACS,” is described in the journal eLife.

Can we drill into Yellowstone to stop it from erupting?

Posted by in category: climatology

In some cases, limited scientific drilling for research can help us understand magmatic and hydrothermal (hot water) systems; however, drilling to mitigate a volcanic threat is a much different subject with unknown consequences, high costs, and severe environmental impacts. In addition to the enormous expense and technological difficulties in drilling through hot, mushy rock, drilling is unlikely to have much effect on whatever magma is stored beneath Yellowstone. At near-magmatic temperatures and pressures, any hole would rapidly become sealed by minerals crystallizing from the natural fluids that are present at those depths.

Additionally, Yellowstone National Park is protected from geothermal resource development. World-famous features like Old Faithful Geyser and Grand Prismatic Spring depend on heat provided by the magma chamber deep below Yellowstone’s surface. Any allowed geothermal extraction would lower the pressure on the existing geysers and hot springs, altering their behavior and, in many cases, causing them to disappear.

Concerns about volcanic eruptions at Yellowstone typically involve a cataclysmic, caldera-forming event, but it’s unknown whether any such eruption will ever occur there again. Current seismic imaging of the magma reservoir reveals a system that is too crystalline to erupt on a grand scale.

No asteroids needed: ancient mass extinction tied to ozone loss, warming climate

Malformed spores suggest powerful storms drove ozone loss and led to sterilizing UV radiation.
