The US Space Force Is About to Finally Leave the Planet – Futurism

Published

Go Time

The recently-formed U.S. Space Force will actually venture out into orbit for the first time on Thursday.

The mission, which will send a military communication satellite into orbit from Florida’s Cape Canaveral Air Force Station, is still on track for its 3 p.m. EST launch, according to Ars Technica. That’s because, unlike other groups like SpaceX and NASA, military spaceports in the U.S. have thus far escaped unscathed by the coronavirus pandemic.

However, the mission has been altered somewhat by the pandemic, even if the launch itself is proceeding as scheduled. Ars Technica reports that the usual fanfare surrounding a rocket launch, like a social media event and other forms of outreach, have been cancelled.

That said, people can still watch the launch if they so desire on this livestream.

Final Piece

If the Space Force mission succeeds, the U.S. military will be able to bring online a new constellation of communication satellites. With the satellite that’s being launched today in place, the military will finally be able to replace the outdated network that it’s been relying on.

Five of the six satellites in the new network are already in place, Ars Technica reports. Some have been waiting in geostationary orbit for ten full years, as the military has been slowly sending them up since 2010.

Satellite-carrying rocket 'lost' after New Zealand launch – The Jakarta Post – Jakarta Post

Published

on



A commercial rocket carrying seven satellites was “lost” after take-off Sunday from a New Zealand launch pad, the owner Rocket Lab said.

“We lost the flight late into the mission,” Peter Beck, Rocket Lab’s founder and chief executive, tweeted. 

“I am incredibly sorry that we failed to deliver our customers’ satellites today. Rest assured we will find the issue, correct it and be back on the pad soon.”

Rocket Lab lists itself as a US company with headquarters at a wholly-owned New Zealand subsidiary and specializes in delivering small satellites to low Earth orbit.

Its backers include US companies Khosla Ventures, Bessemer Venture Partners, Lockheed Martin, Promus Ventures and Data Collective.  

The failed mission, the company’s 13th payload launch, had been named “Pics Or It Didn’t Happen”.

In a statement on its website, Rocket Lab said it had experienced an “anomaly” four minutes into the flight and was working closely with the Federal Aviation Administration in the United States to identify the cause.

The rocket was carrying satellites for companies Spaceflight, Canon Electronics, Planet and In-Space Missions, Beck said.

“Today’s anomaly is a reminder that space launch can be unforgiving, but we will identify the issue, rectify it, and be safely back on the pad as soon as possible.”

July's full 'Buck Moon' wows skywatchers despite lackluster lunar eclipse – Space.com

Some skywatchers may have seen more than mere fireworks in the night sky during their Fourth of July celebrations on Saturday: the full moon.

Overnight on Saturday and Sunday (July 4 and 5), July’s full “Buck Moon” dipped through the outermost edges in a penumbral lunar eclipse. While the lunar eclipse was subtle and difficult to see — one eclipse expert said it would “invisible” — the full moon was still a spectacular sight for skywatchers around the world. 

This weekend’s eclipse was the third of four penumbral lunar eclipses in lunar eclipses. During a lunar eclipse, Earth comes between the moon and the sun, and the three align exactly (or almost exactly.) Because of this alignment, Earth casts a shadow on the moon’s face.

In a total lunar eclipse, the moon is complete in Earth’s shadow and can take on a blood-red hue. But during a penumbral lunar eclipse, only the diffuse outer shadow of the Earth, known as the penumbra, falls onto the face of the moon. This means  the darkening effect is very slight. 

You can see how imperceptible the effect was in July’s lunar eclipse in the photos of July’s full Buck Moon below.

All lunar eclipses occur when the moon is full. Interestingly enough, during eclipses (but also during every full and new moon), gravitational forces on Earth are particularly strong because of the sun’s influence when it aligns with the moon and our planet. That makes our planet’s oceans bulge and causes high tides to be higher and low tides to be lower. 

After this weekend’s firework-filled eclipse fun, the next lunar eclipse, which will also be a penumbral eclipse, will be this fall, on Nov. 29-30.

While this weekend’s lunar eclipse was nearly imperceptible for many us, it was theoretically visible to people in Southern and Western Europe, most of Africa, most of North America, South America, the Pacific, Atlantic and Indian Ocean regions and Antarctica. Those in the U.S. may have even spotted the eclipse while looking up to enjoy fireworks displays, as the lunar eclipse fell on July 4, which is Independence Day in the country. 

The eclipse’s many nicknames come from a variety of sources. Penumbral lunar eclipses that occur in July are given the “Thunder Moon” moniker, which comes from the summer storms that happen around the time of July’s full moon, according to the Old Farmer’s Almanac

Indigenous American tribes have also called this moon the “Buck Moon” because this event also usually coincides with the time when male deer begin to grow new, velvety antlers. Some also know it as the “Hay Moon” because it usually comes at a time when farmers are stocking their barns with hay, according to Earthsky.org

Also, in addition to simply looking up, enjoying the sight and learning more about our rocky satellite, throughout history, many cultures around the world have adopted customs in accordance with lunar eclipses. For example, many have viewed lunar eclipses as times or portents of danger.

White-throated sparrows' new tune 'going viral' – ABC News

Published

on


Researchers speculate that female sparrows may be attracted to it.

This is an Inside Science story.

When researchers first noticed white-throated sparrows singing a strange song in the Canadian province of British Columbia, they figured it was a regional dialect. Dialects are common among birds and other singing animals living in isolated populations.

Then the song began to spread.

“It was very exciting to sort of see this wave going across the country,” said Ken Otter, a biologist at the University of Northern British Columbia. “It basically is like it’s going viral.”

Traditional white-throated sparrow songs begin with three long whistles and end with a series of rapid notes in sets of three. Canadian birdwatchers liken the rhythm to “Oh, my sweet Canada, Canada, Canada.” With the new song, birds drop the third note from some of the triplet phrases, turning the song into “Oh, my sweet Cana Cana Canada.”

Using recordings from a variety of sources, the researchers saw that the new doublet song spread eastward in the last two decades. By 2019, only the birds on the country’s far eastern edge still sang the classic triplet song. The new song spread much like a disease — in fact, the researchers used disease-tracking statistical techniques to analyze their data. But as a behavioral phenomenon, it resembled human trends and fads, said Otter. He and his colleagues published their findings July 2 in the journal Current Biology.

How did this happen? The sparrows’ movements offer clues.

Historically, white-throated sparrows bred east of the Rocky Mountains in Canada and spent winters in the central and eastern U.S. But in the mid-20th century, a breeding population appeared west of the Rockies in British Columbia. Around the same time, sparrows began showing up in California during the winter.

Researchers initially assumed the birds on either side of the Rockies were isolated from each other, with western birds overwintering in California and eastern birds overwintering in the other parts of the U.S. But genetic testing and data from tracking devices revealed that birds from both regions were intermingling.

Otter and his colleagues found that some of the British Columbia birds overwintered in California, while the rest overwintered in Texas and Oklahoma — part of the birds’ historical winter range that is also used by sparrows from the Canadian prairies. White-throated sparrows sing during winter, so birds from both sides of the Rockies would have a chance to learn from each other.

Otter and his colleagues aren’t sure why the doublet song became so popular, but they speculate that female sparrows may be attracted to the novelty. Indeed, a third song variant that adjusts the volume mid-note has recently turned up in the West, and it appears to be spreading even faster than the doublet song.

Citizen science projects such as eBird and Xeno-canto make it possible to study such phenomena more effectively than ever before.

“Suddenly, you have people all across North America uploading songs,” Otter said. “There’s no way that we could look at this kind of spread if we didn’t have that massive proliferation of citizen scientists.”
