If you’ve seen any space news this past week, you may already know that Ingenuity, the adorable little helicopter that has exceeded all expectations in its exploration of Mars, has ended its mission.

After Three Years on Mars, NASA’s Ingenuity Helicopter Mission Ends – NASA

Originally designed as a technology demonstration to perform up to five experimental test flights over 30 days, the first aircraft on another world operated from the Martian surface for almost three years, performed 72 flights, and flew more than 14 times farther than planned while logging more than two hours of total flight time.

Ingenuity arrived on Mars with the Perseverance rover almost two years ago. It began as a limited technology demonstration but quickly became a scout for the rover’s mission and a fan favorite. Now, after 72 flights, a difficult landing has caused irreparable damage to its rotor blades.

Here’s what NASA Administrator Bill Nelson had to say about the end, and what the plucky little project managed to accomplish.

Ingenuity, and its swatch from the original Wright flyer, will remain on the Martian surface as a testament to how far we’ve come.

“That remarkable helicopter flew higher and farther than we ever imagined and helped NASA do what we do best – make the impossible, possible.”

— Bill Nelson, NASA Administrator

This weekend join me in raising a glass to the first powered, controlled flight on another world, and to the little ‘copter that could.

Thanks, Ingenuity.

It’s Monday, I’m back at work, and while things are moving along fine I’d be lying if I said I didn’t wonder what a day in space would be like instead. 

Let’s take a little break and go to Mars, shall we?

NASA’s Curiosity Rover Captures a Martian Day, From Dawn to Dusk – NASA Mars Exploration

Rover drivers normally rely on Curiosity’s Hazcams to spot rocks, slopes, and other hazards that may be risky to traverse. But because the rover’s other activities were intentionally scaled back just prior to conjunction, the team decided to use the Hazcams to record 12 hours of snapshots for the first time, hoping to capture clouds or dust devils that could reveal more about the Red Planet’s weather.

Of Notes and Meteors

Did this post start out life as a path to a map of sci-fi story locations in space? It did, and then I realized that in my haste, I’d picked a draft I’d already posted before.

It happens, especially on days when one is juggling not one not two not three but four big projects, and one has absolute reams of notes in the “blog post ideas” folder.

So now I’m here with an update, still space-related but also experiential. It has to do with the Geminid meteor shower.

Bundle up and look to the sky: It’s time for one of the best meteor showers of the year

The shower will be at its peak on Wednesday night and early Thursday morning, though you’ll likely see some meteors in the nights before and after…

“The meteors will seem to shoot out of the constellation Gemini (hence the name) but could streak across pretty much any part of the sky,” Wiegert said. “So if you can find a dark place, with a good view of the sky in any direction, you could get a good view of the Geminids.”

Happy hunting!

Why isn’t there any sound in space? An astronomer explains why in space no one can hear you scream

In space, no one can hear you scream.

You may have heard this saying. It’s the tagline from the famous 1979 science fiction movie “Alien.” It’s a scary thought, but is it true? The simple answer is yes, no one can hear you scream in space because there is no sound or echo in space.

I’m a professor of astronomy, which means I study space and how it works. Space is silent – for the most part.

University of Arizona Distinguished Professor of Astronomy Chris Impey explains the science behind the Alien tagline, showcases slinkies as sound waves, and discusses why humans can’t speak across space but phenomena like galaxies and black holes can.

Also, a fun fact I did not know: “The word vacuum comes from the Latin word for empty.”

What’s happening in the night skies this month? I have no idea, actually, but this calendar does!

Astronomy Calendar for December, 2023 for Ottawa, Canada

What’s this? The Pheonicid Meteor Shower will be visible starting tomorrow night and showcases meteors seemingly coming from the Phoenix constellation?

Cool cool cool. And what’s the Phoenix constellation? (Clicks on “learn more” and voila: Pheonicid meteor shower 2023).

Although that particular arrangement of stars isn’t saying phoenix to me so much as… curling stone.

This week, you have a once-in-a-430 year chance to see a new comet. Comet Nishimura was just discovered last month, and will be gone by the end of the week.

Nishimura green comet: what is it, how to see it and when it will be back – NPR

Scientists determined that this comet takes about 430 years to orbit the sun.

So the last time it was visible from Earth was in the late 1500s — before Galileo Galilei pointed his telescope to the sky.

The last time this comet came through these parts was just a few years before Galileo invented his telescope. The comet was discovered just last month, by an amateur astronomer named Hideo Nishimura.  

There are good images of the comet as well as detailed location information here: The new comet Nishimura is closest to Earth today.

I should have posted this a few days ago, because the comet is now passing us. If you’re interested, the comet is visible this week with binoculars or a telescope, but only with effort and only from the northern hemisphere. Try looking toward the east, low on the horizon, before sunrise, and look for the constellation Leo.

I don’t have good binoculars or a telescope, but that’s fine. It’s enough for me to know that this comet, and so many other fascinating objects, are still out there. 

Waiting to be discovered.

Oh hey, I forgot to give you a heads up about the “asteroid big enough to wipe out a city” that flew past us over past weekend.

‘City killer’ asteroid to pass harmlessly between Earth and moon

The good news is that we’re all still here. Hooray!

Let’s give one last shoutout to our visitor from outer space. C/2022 E3 (ZTF), the universe’s charismatic invitation to look up and wonder about our past and our future, is at its closest point to Earth today. That means it will be at its brightest. If the world and weather are on your side, you might be able to see it with the naked eye. Look to the north after sunset. Is it fuzzy? Is it green? It might just be a comet!

Green comet C-2022 E3 (ZTF) will be closest to Earth today | Space

During the comet’s perigee, it will come to within a distance of around 26 million miles (42 million kilometers) from our planet, which is equivalent to about 28% of the distance between Earth and the sun. If you’ve been waiting to get a look at C/2022 E3 (ZTF) before it speeds away, now is your best chance. You can also watch the comet live online on Feb. 1 in a free webcast at 11 p.m. EST (0400 GMT) from the Virtual Telescope Project.

If the weather isn’t cooperating where you are or you have a hard time finding it or you just can’t see yourself outside in the cold, there will be a live webcast tonight. Pour a cup of hot cocoa and wave as The Green Comet flies by!

Today is the first test of humanity’s nascent planetary defense system. Like Armageddon, except scientists are the heroes.

NASA will hit an asteroid with a spacecraft to change its course : NPR

“It’s just a spacecraft that is going to go and smack an asteroid.” Oh, is that all?

* * *

NASA’s Double Asteroid Redirection Test (DART) is scheduled to crash a spacecraft into an asteroid to test our ability to nudge potentially dangerous near-Earth objects into safer trajectories. That is excellent, and we can watch it.

How to Livestream NASA Smashing an Asteroid to Test Planetary Defense Plan

The impact day broadcast of the actual test will start on Monday, September 26 at 6 p.m. EDT, which you can watch on NASA TV, a livestream on NASA’s YouTube channel.

* * *

What will happen and how will we know? 

Ground-based telescopes are key to DART asteroid mission success | Space

On Monday (Sept. 26), the Double Asteroid Redirection Test (DART) spacecraft will slam into a small space rock called Dimorphos — on purpose, at a staggering 4 miles (6.6 kilometers) per second. The exercise comes in the name of planetary defense, which aims to protect human civilization from any large asteroid that may be on a collision course. For the mission to succeed, scientists need to measure exactly how much the orbit of Dimorphos around its larger companion, Didymos, speeds up. And the DART spacecraft won’t be in any shape to make that measurement itself, so mission personnel are relying on ground-based telescopes to track the aftermath of impact.

If this trial run works, terrific, but even failure would better prepare us to defend Earth.
