Based on the photos and videos posted on social media, Geoff Robertson, the past president of the Edmonton Centre of the Royal Astronomical Society of Canada, says the meteor was likely the size of a desk or refrigerator, and some of it may have survived the fall to earth.
“Looking at the videos, I saw some flashes as it was coming down, indicating it was probably breaking up. So I would say probably some pieces did eventually make their way down, landing on the ground somewhere,” says Robertson.
The American Meteor Society, using data compiled from the reports, estimates the meteor’s flight path ended just southwest of Athabasca.
Robertson says a team from the University of Alberta will likely triangulate the data and put together a team to go out and search for any pieces that survived.
“The fragments slow down to quite slow, I mean when it hits the earth’s atmosphere these things are going at [between] 11 and 25 kilometres per second, but by the time they hit the ground they’re just falling at terminal velocity, so that’s just less than a couple hundred kilometres per hour.”
He adds that, if anything can be recovered, then they can analyze the fragments to find out more information.
“Whether it’s an iron meteor or a ‘stony’ meteor, and if they get enough data they can actually track back the meteor’s original orbit around the sun and find out where it actually came from.”
Robertson says it’s not guaranteed that any pieces did survive the fall, and there’s also the possibility that any fragments that did survive could have landed in snow, and may not be recovered.
He also says it’s not surprising to see reports coming from all over, and Mike Hankey, the Operations Manager of the American Meteor Society, says it’s not surprising that the flash was seen as far from the site as Grande Prairie.
“You could see (the flash) from up to 600 kilometres away on either side potentially, especially if it’s really bright and based on people’s elevation,” says Hankey.
Hankey adds that anyone who spots a meteor or a fireball can submit reports to the American Meteor Society, which will help narrow down the exact locations that these objects fall, and lead to researchers potentially recovering any surviving fragments.
New Mars image from rover landing site shows the red planet in high definition – CTV News
The Perseverance rover has had a chance to settle in on Mars since landing last Thursday, so it’s doing what every new resident does these days — sending back photos of its new home.
In this case, it’s a steady stream of amazing imagery from another planet.
The rover’s Mastcam-Z instrument, a pair of zoomable color cameras, returned 142 images of its landing site on February 21. The teams at NASA stitched them together to create the instrument’s first 360-degree panorama.
This is the first high-definition look at Jezero Crater, the site of a 3.9 billion-year-old dry lake bed where the rover will search for signs of ancient life over the next two years.
In the image, the crater rim and the cliff face of an ancient river delta can be seen in the distance. It’s not unlike images shared previously by NASA’s Curiosity rover of its exploration site in Gale Crater.
“We’re nestled right in a sweet spot, where you can see different features similar in many ways to features found by Spirit, Opportunity, and Curiosity at their landing sites,” said Jim Bell, principal investigator of the Mastcam-Z instrument at Arizona State University’s School of Earth and Space Exploration, in a statement.
Perseverance also sent back a panorama using its Navcams, or navigation cameras, over the weekend.
Mastcam-Z is a new feature on Perseverance that builds off of lessons learned from the Curiosity rover’s Mastcam instrument. Curiosity’s Mastcam has two cameras with a fixed focal length, while Mastcam-Z has zooming capability.
These two cameras are like high-definition eyes on Perseverance as she shares her view with a team of scientists and engineers at home.
They sit on the rover’s mast, reaching eye level for a person who stands just over 6 and a half feet tall. The cameras are 9.5 inches apart to allow for stereo vision.
The color imagery produced by Mastcam-Z is a lot like the quality you would expect from your own digital HD camera, NASA officials said. These cameras can not only zoom but also can focus to capture video, panoramas and 3D images.
This will allow scientists on the mission’s team to examine objects that are both close and far away from the rover.
In the panorama, details as small as 0.1 to 0.2 inches across can be seen if an object is near the rover, while those between 6.5 to 10 feet across in the distance are also visible.
These capabilities will aid the overall goals of the mission in both understanding the geologic history of the crater and identifying the types of rock that the rover’s other instruments should study. The views afforded by Mastcam-Z will also help scientists determine which rocks they should collect samples from that will eventually be returned to Earth by future missions.
The team working on the Mastcam-Z instrument will share more details about the panorama Thursday, February 25 at 4 p.m. ET on NASA’s website and social media accounts.
The best images from NASA's Perseverance rover so far – CTV News
Almost as soon as NASA’s Perseverance rover landed on Mars it was beaming back images of its surroundings.
The first pictures were black and white and a little grainy. They were soon followed by video and high definition images of the rocks, ridges and the rover itself.
Here’s a collection of some of the best images to come from Perseverance’ so far.
This is the first image NASA’s Perseverance rover sent back after touching down on Mars on Feb. 18, 2021. The view, from one of Perseverance’s Hazard Cameras, is partially obscured by a dust cover. (NASA/JPL-Caltech)

As a teaser to some of the ground-breaking video to come, NASA released this image of Perseverance being gently lowered onto Mars’s surface during its descent on Feb. 18. (NASA via AP)
In video sent back by Perseverance, we can see the spacecraft’s parachute open, revealing a mix of white and orange markings on the inside. These were later revealed to be part of secret message left by NASA systems engineer Ian Clark. Clark used binary code to spell out “Dare Mighty Things” on the stripes of the 21-metre parachute. Also included were the GPS coordinates of the mission’s headquarters in Pasadena, Calif. (NASA/JPL-Caltech via AP)
While we’ve seen panorama images from previous rover missions, Perseverance’s high definition cameras are revealing details from Mars like we’ve never seen before. (NASA/JPL-Caltech via AP)

ROVER ‘FAMILY HISTORY’
Along with loads of science instruments Perseverance is also boasting a decal showing the history of NASA’s rovers on Mars. (NASA/JPL-Caltech/ASU/MSSS)
TRIBUTE TO DESCENT STAGE
“A moment of respect for the descent stage,” NASA tweeted from the Perseverance’s twitter account after about a week after the landing. The image above shows a smoke plume from where the descent stage (the part of the spacecraft that lowered Perseverance gently to Mars’ surface) made its “intentional surface impact.” (@NASAPersevere/Twitter)

In this illustration of its descent to Mars, the spacecraft carrying NASA’s Perseverance rover slows down using the drag generated by its motion in the Martian atmosphere. Hundreds of critical events must execute precisely on time for the rover to land on Mars safely. Entry, descent, and landing, or “EDL,” begins when the spacecraft reaches the top of the Martian atmosphere, traveling nearly 12,500 mph. The cruise stage separates about 10 minutes before entering into the atmosphere, leaving the aeroshell, which encloses the rover and descent stage, to make the trip to the surface.
