"Moon wobble", climate change is expected to cause flood surges in the coastal areas of the United States, the study says – Texasnewstoday.com

According to a new study, “moon wobble” and climate change cause rapidly increasing storm surge floods on all coastlines in the United States.

But what is “moon wobble”? According to NASA, this is not a new phenomenon.

This is a periodic change in the lunar orbit every 18.6 years and has been recorded since 1728.

Wobble affects the gravitational pull of the Moon and can suppress or amplify the tides of the oceans on Earth. According to NASA, it can be mixed with rising sea levels, putting risks to people living in coastal areas.

“Half of the 18.6 year cycle of the Moon suppresses the normal daily tides of the Earth. High tides are lower than normal and low tides are higher than normal. In the other half of the cycle, tides are amplified. High tides are high and low tides are low, “the study states.

According to NASA, the next cycle, which is expected to amplify tides again, will occur in the mid-2030s. Meanwhile, “flood surges” are expected on the US coastline, Hawaii and Guam.

The Gulf of Mexico coastline was mentioned as a particular concern as it is more vulnerable to floods due to its relatively narrow sea level distribution.

“Lowlands near sea level are increasingly endangered and suffering from increased floods, and it only gets worse,” said NASA administrator Bill Nelson. “The combination of lunar attraction, sea level rise and climate change will continue to exacerbate our coastlines and coastal floods around the world. NASA’s sea level change team is committed to the flood-affected environment and people’s lives. We provide important information so that we can plan, protect and prevent damage. “

Compared to the high tides of hurricanes, floods at high tide contain only a small amount of water.

Buck Moon rises over Oshawa harbour – insauga.com

July’s orange- or yellow-tinted full moon – known as a Buck Moon – arrived at 10:36 p.m. Friday night.

It’s called the Buck Moon because the antlers of male deer are in full-growth mode at this time.

Indigenous people of Canada have several other names for the phenomenon, including Berry Moon (Anishinabe), Feather Moulting Moon (Cree), Salmon Moon, (Tlingit) and Raspberry Moon (Algonquin, Ojibwe).

The full moon can be viewed in all its glory until tomorrow night.

NASA clears Boeing Starliner for July 30th test flight to ISS – Yahoo Movies Canada

Published

 on


More than 18 months after its failed first attempt to make it to the International Space Station, Boeing’s Starliner is ready for a second shot. Following a flight readiness review, NASA is moving forward with the craft’s upcoming July 30th uncrewed orbital flight test. Unless there’s an unforeseen delay, the capsule will launch from the Space Force’s Cape Canaveral Station mounted on an Atlas V rocket at 2:53PM ET. Should NASA postpone the flight, it will again attempt to carry out the test on August 3rd at the earliest.

The purpose of the flight is for NASA to conduct an end-to-end test of Starliner’s capabilities. It wants to know if the capsule can handle every aspect of a trip to the ISS, including launch, docking as well as atmospheric re-entry. “[Orbital Flight Test-2] will provide valuable data that will help NASA certify Boeing’s crew transportation system to carry astronauts to and from the space station,” the agency said.

If the flight is a success, NASA will move forward with a crewed test of the Starliner. Steve Stich, commercial crew program manager at NASA, said that could happen “as soon as later this year.” Both Boeing and NASA have a lot invested in the viability of Starliner. For the aerospace company, its decision not to conduct an end-to-end test of the craft before its failed 2019 flight left the agency “surprised,” leading to questions about the project. Meanwhile, NASA is keen to have two capsules that can ferry its astronauts to the ISS. Right now, it’s limited to just SpaceX’s Crew Dragon. “It’s very important for the commercial crew program to have two space transportation systems,” Stich told reporters.

SpaceX lands NASA launch contract for mission to Jupiter's moon Europa – Euronews

Published

By Steve Gorman

LOSANGELES – Elon Musk’s private rocket company SpaceX was awarded a $178 million launch services contract for NASA‘s first mission focusing on Jupiter’s icy moon Europa and whether it may host conditions suitable for life, the space agency said on Friday.

The Europa Clipper mission is due for blastoff in October 2024 on a Falcon Heavy rocket owned by Musk’s company, Space Exploration Technologies Corp, from NASA‘s Kennedy Space Center in Florida, NASA said in a statement posted online.

The contract marked NASA‘s latest vote of confidence in the Hawthorne, California-based company, which has carried several cargo payloads and astronauts to the International Space Station for NASA in recent years.

In April, SpaceX was awarded a $2.9 billion contract to build the lunar lander spacecraft for the planned Artemis program that would carry NASA astronauts back to the moon for the first time since 1972.

But that contract was suspended after two rival space companies, Jeff Bezos’s Blue Origin and defense contractor Dynetics Inc, protested against the SpaceX selection.

The company’s partly reusable 23-story Falcon Heavy, currently the most powerful operational space launch vehicle in the world, flew its first commercial payload into orbit in 2019.

NASA did not say what other companies may have bid on the Europa Clipper launch contract.

The probe is to conduct a detailed survey of the ice-covered Jovian satellite, which is a bit smaller than Earth’s moon and is a leading candidate in the search for life elsewhere in the solar system.

A bend in Europa’s magnetic field observed by NASA‘s Galileo spacecraft in 1997 appeared to have been caused by a geyser gushing through the moon’s frozen crust from a vast subsurface ocean, researchers concluded in 2018. Those findings supported other evidence of Europa plumes.

Among the Clipper mission’s objectives are to produce high-resolution images of Europa’s surface, determine its composition, look for signs of geologic activity, measure the thickness of its icy shell and determine the depth and salinity of its ocean, NASA said.
