Trump touts Space Force, moon and Mars plans in State of the Union address – Space.com

Space exploration got a couple of shout-outs in President Donald Trump’s State of the Union address Tuesday night (Feb. 4).

During the nearly 80-minute speech, Trump touted the recent establishment of the Space Force — the first new U.S. military branch to be stood up since the Air Force in 1947 — as one of his administration’s key accomplishments thus far. 

And one of the president’s special guests for the State of the Union, which is held every year in the House of Representatives chamber of the U.S. Capitol building, was a kid with Space Force dreams.

“In the gallery tonight, we have a young gentleman,” Trump said. “And what he wants so badly — 13 years old — Iain Lanphier, he is an eighth-grader from Arizona. Iain, please stand up. Iain has always dreamed of going to space. He was the first in his class and among the youngest at an aviation academy. He aspires to go to the Air Force Academy, and then he has his eye on the Space Force. As Iain says, ‘Most people look up at space; I want to look down on the world.'”

President Trump also referenced NASA’s Artemis program of crewed lunar exploration. Artemis aims to put astronauts on the surface of the moon by 2024 and use Earth’s nearest neighbor as a training ground for crewed missions to Mars in the 2030s.

NASA originally targeted 2028 for the human lunar landing, which will be the first since the Apollo 17 mission in 1972, but Vice President Mike Pence announced an accelerated timeline in March of last year. (Last month, the House Science Committee introduced an appropriations bill that would re-target 2028 for the lunar landing. But that bill has a long way to go before being enacted as law.)

“In reaffirming our heritage as a free nation, we must remember that America has always been a frontier nation. Now we must embrace the next frontier: America’s manifest destiny in the stars,” Trump said during last night’s speech. “I am asking Congress to fully fund the Artemis program to ensure that the next man and first woman on the moon will be American astronauts, using this as a launching pad to ensure that America is the first nation to plant its flag on Mars.”

We’ll soon see what kind of funding he has in mind; the White House is expected to unveil its 2021 federal budget request on Monday (Feb. 10). 

President Trump has made a fair bit of space news during his first three years in office. There’s the Space Force, of course, and Space Policy Directive-1, which officially set the nation’s human spaceflight program on its moon-to-Mars path. (President Barack Obama had directed NASA to get people to Mars, but to use an asteroid as a stepping stone.)

Trump has also signed two other space policy directives, which deal with space traffic management and the regulation of commercial activities in space, respectively. And in 2017, Trump resurrected the National Space Council (NSC), which helps steer American space policy.

Pence chairs the NSC, which had last been active in the early 1990s, during the presidency of George H.W. Bush.

STEVE appears over Canada during 'surprise' solar storm – Livescience.com

Published

 on


In the dark of Sunday night and Monday morning (Aug. 7 and 8), a surprise solar storm slammed into Earth, showering our planet in a rapid stream of charged particles from the sun. The resulting clash of solar and terrestrial particles in Earth‘s atmosphere caused stunning auroras to appear at much lower latitudes than usual — and, in southern Canada, triggered a surprise cameo from the mysterious sky phenomenon known as STEVE.

Alan Dyer, an astronomy writer and photographer based in southern Alberta, Canada, caught the wispy ribbons of green and violet light on camera as they shot through the sky.

“STEVE lasted about 40 minutes, appearing as the … aurora to the north subsided,” Dyer wrote on Twitter (opens in new tab) on Aug. 8. “STEVE was ‘discovered’ here so he likes appearing here more than anywhere else!”

As Dyer noted, the strange sky glow called STEVE was first described by citizen scientists and aurora hunters in northern Canada in 2017. STEVE is typically composed of an enormous ribbon of purplish light, which can hang in the sky for an hour or more, accompanied by a “picket fence” of green light that usually disappears within a few minutes. 

The glowing river of light may look like an aurora, but it’s actually a unique phenomenon that was considered “completely unknown” to science upon its discovery. Today, scientists have a slightly better idea of what’s going on. 

STEVE (short for “strong thermal velocity enhancement”) is a long, thin line of hot gas that slices through the sky for hundreds of miles. The hot air inside STEVE can blaze at more than 5,500 degrees Fahrenheit (3,000 degrees Celsius) and move roughly 500 times faster than the air on each side of it, satellite observations have shown.

Whereas the northern lights occur when charged solar particles bash into molecules in Earth’s upper atmosphere, STEVE appears much lower in the sky, in a region called the subauroral zone. That likely means solar particles aren’t directly responsible for STEVE, Live Science previously reported. However, STEVE almost always appears during solar storms like Sunday’s, showing up after the northern lights have already begun to fade.

One hypothesis suggests that STEVE is the result of a sudden burst of thermal and kinetic energy in the subauroral zone, somehow triggered by the clash of charged particles higher in the atmosphere during aurora-inducing solar storms. However, more research is needed to uncover the true secrets of STEVE. In the meantime, we can simply bask in its otherworldly glow and wave back at its twinkling green fingers.

Perseid meteor shower: when to catch it in Manitoba | CTV News – CTV News Winnipeg

Published

 on


The peak of a spectacular space light show is expected to happen by the end of the week.

The Perseid meteor shower is expected to be at its best and brightest the night of Aug. 12 going into the morning of Aug. 13.

Scott Young, an astronomer at the Manitoba Museum, said this is an annual event that will produce dozens of shooting stars throughout the night.

“Every meteor is a piece of dust from outer space that is crashing into the earth at tremendous speed and basically vaporizing in a poof and a flash of light, and that it is what we see as a meteor,” he said. “On certain nights of the year, the earth in its orbit around the sun actually goes through a cloud of dust, sort of like an interplanetary dust bunny, essentially, and all that dust hits on the same night … and so we are basically crashing through the dust left behind by a comet.”

The cloud of dust was left behind by the comet Swift-Tuttle, which last passed by the earth in 1992. Since then, the meteor shower has reached its peak between Aug. 11 and 13.

For those who are looking to enjoy the meteor show, Young suggests people get away from city lights, especially this year as the shower also coincides with a full moon.

“The moon can wash out those fainter meteors, and also if you are in the city, city lights will also wash out those fainter meteors. If you want to see the best show, you want to go late Friday after midnight, into the early morning hours of Saturday.”

If people can’t see the shower that night, Young says not to worry as the Perseid meteor shower is already happening right now and will continue to the end of August. As long as people are away from bright lights, Young says they should be able to see some shooting stars.

He recommends going to places like Birds Hill Provincial Park to enjoy the shower, but noted if people can find a place that is away from direct light, whether that be a park within the City of Winnipeg, or even a person’s backyard, he suggests people will be able to see something.

Once the meteor shower is over, however, Young does have a cautionary tale to share.

“We get dozens calls of people seeing an interesting rock on the ground and thinking that they’ve found a meteorite. There are no meteorites that will fall and actually land on the ground from this shower. These are little pieces of dust and they completely vaporize in the atmosphere. You might find meteorites out there, but they are very, very rare and so don’t get all excited about every rock that you find after this. The odds are it’s a meteor-wrong and not a meteorite.”

Young said weather-permitting, the Manitoba Museum will livestream the shower on its social media channels.

NASA’s Hubble Space Telescope captured two festive-looking nebulas – Tech Explorist

Published

 on


The image shows NGC 248, about 60 light-years long and 20 light-years wide. They are two nebulas, situated to appear as one. The nebulas, together, are called NGC 248.

Initially discovered in 1834 by the astronomer Sir John Herschel, NGC 248 resides in the Small Magellanic Cloud, located approximately 200,000 light-years away in the southern constellation Tucana.

Small Magellanic Cloud is a dwarf galaxy that is a satellite of our Milky Way galaxy. The image is part of a study called Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE).

The dwarf satellite galaxy contains several brilliant hydrogen nebulas, including NGC 248. Intense radiation from the brilliant central stars is heating hydrogen in each nebula, causing them to glow red.

The study’s principal investigator, Dr. Karin Sandstrom of the University of California, San Diego, said“The Small Magellanic Cloud has between a fifth and a tenth of the amount of heavy elements that the Milky Way does. Because it is so close, astronomers can study its dust in great detail and learn about what dust was like earlier in the history of the universe.”

“It is important for understanding the history of our galaxy, too. Most of the star formation happened earlier in the universe, at a time when there was a much lower percentage of heavy elements than there is now. Dust is a critical part of how a galaxy works, how it forms stars.”

The image is part of a study called Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE). The data used in this image were taken with Hubble’s Advanced Camera for Surveys in September 2015.
