Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s broadcast of the April 8, 2024, total solar eclipse has won an Emmy Award for Excellence in Production Technology.
At the 76th Technology & Engineering Emmy Awards on Dec. 4, in New York City, the Academy of Television Arts & Sciences announced the win. Walt Lindblom and Sami Aziz accepted the award on behalf of the agency. For the broadcast, Lindblom served as the coordinating producer and Aziz served as the executive producer.
“By broadcasting the total solar eclipse, this team brought joy and wonder for our Sun, Moon, and Earth to viewers across America and the world,” said Will Boyington, associate administrator for the Office of Communications at NASA Headquarters in Washington. “Congratulations to the production team, whose efforts demonstrate the hard work and dedication to the sharing the marvel that makes our solar system something we strive to understand.”
NASA’s live broadcast coverage of the 2024 total solar eclipse was the most complex live project ever produced by the agency. In total, NASA’s eclipse broadcasts garnered almost 40 million live and replay views across its own distribution channels, including on NASA+, the agency’s free streaming service. Externally, the agency’s main broadcast was picked up in 2,208 hits on 568 channels in 25 countries.
“Our unique place in the solar system allows us on Earth to witness one of the most spectacular science shows nature has to offer. NASA’s production team captured the action every step of the way across the path of totality, including the rare glimpse of the Sun’s corona,” said Nicky Fox, associate administrator for science at NASA Headquarters. “Congratulations to the NASA team for successfully showing the 2024 total solar eclipse through the eyes of NASA for the whole world to experience together.”
The broadcast spanned three hours, showcasing the eclipse across seven American states and two countries. From cities, parks, and stadiums, 11 hosts and correspondents provided on air commentary, interviews, and live coverage. Viewers tuned in from all over the world, including at watch parties in nine locations, from the Austin Public Library to New York’s Times Square. An interactive “Eclipse Board” provided real time data analysis as the Moon’s shadow crossed North America.
Live feeds from astronauts aboard the International Space Station and NASA’s WB-57 high-altitude research aircraft were brought in to provide rare and unique perspectives of the solar event. To make this possible, NASA deployed and enabled 67 cameras, 6 NASA Wide Area Network control rooms, 38 encoders, and 35 decoders. The team coordinated 20 live telescope feeds which represented 12 locations across the path of totality.
NASA’s eclipse broadcast won another Emmy award earlier this year at the 46th Annual News & Documentary Emmy Awards for Outstanding Live News Special. Additionally, the show received an Emmy nomination for Outstanding Show Open or Title Sequence – News. NASA’s eclipse communication and broadcast efforts also won two Webby Awards and two Webby People’s Voice Awards.
On April 8, 2024, North America's last total solar eclipse until 2045 moved across the continent. It made landfall in Mexico, crossed the United States from ...
December is an exciting month for those who like to look up, with a comet, a meteor shower, and a conjunction between the moon and Jupiter all featuring over the coming weeks.

Mars and Mercury have a cozy conjunction, the Leonid meteor shower delights, and Saturn’s rings are…disappearing?
That’s What’s Up for November.
Conjunction:
Mars and Mercury will cozy up together in the night sky just after sunset on November 12th.
The planets will experience what is known as a conjunction, meaning they appear close together in the sky from our view (even though in real life, Mars and Mercury are well over 100 million miles apart).
But you can see these two long distance pals close together if you look slightly southwest just after sunset in the early evening sky on November 12th.

Mars will be just to the right above Mercury, and you’ll know it’s Mars by its distinctive reddish-orange color.
Leonid Meteor Shower:
The Leonid meteor shower will sparkle across the skies this month, peaking on November 17th.
NASA/JPL-Caltech
While the meteor shower stretches from November 3rd through December 2nd, it will be at its most visible late on the night of November 16th into the dawn of November 17th, even into the early morning of November 18th.
Look for meteors coming from the shower’s radiant point within the constellation Leo in the eastern sky.
With dark skies, you might see 10-15 meteors per hour with this shower which happens when we travel through the debris trailing the comet 55P/Tempel-Tuttle.
Saturn’s rings disappear
Saturn’s rings will disappear from view this November!
Saturn orbits the sun leaning at an angle of 26.7 degrees. This means that from our view, its rings shift up and down over time.
On November 23, Saturn will be angled in such a way that its rings face us, and since they are so thin they’ll just disappear from view.

But don’t worry, the rings aren’t gone from view forever. As the planet continues to orbit, its rings will gradually become more visible again.
Conclusion + Moon Phases
Here are the phases of the Moon for November.

What’s Up for October? A Supermoon takes over, the Draconid meteor shower peeks through, and the Orionid meteors sparkle across the night sky.
The evening of October 6, look up and be amazed as the full moon is bigger and brighter because – it’s a supermoon!

NASA/JPL-Caltech
This evening, the moon could appear to be about 30% brighter and up to 14% larger than a typical full moon. But why?
Supermoons happen when a new moon or a full moon coincides with “perigee,” which is when the moon is at its closest to Earth all month.
So this is an exceptionally close full moon! Which explains its spectacular appearance.
And what timing – while the supermoon appears on October 6th, just a couple of days before on October 4th is “International Observe the Moon Night”!
It’s an annual, worldwide event when Moon enthusiasts come together to enjoy our natural satellite.You can attend or host a moon-viewing party, or simply observe the Moon from wherever you are.
So look up, and celebrate the moon along with people all around the world!
The supermoon will light up the sky on October 6th, but if you luck into some dark sky between October 6th and 10th, you might witness the first of two October meteor showers – the Draconids!
The Draconid meteor shower comes from debris trailing the comet 21P Giacobini-Zinner burning up in Earth’s atmosphere
These meteors originate from nearby the head of the constellation Draco the dragon in the northern sky and the shower can produce up to 10 meteors per hour!
The Draconids peak around October 8th, but if you don’t see any, you can always blame the bright supermoon and wait a few weeks until the next meteor shower – the Orionids!

NASA/JPL-Caltech
The Orionid meteor shower, peaking October 21, is set to put on a spectacular show, shooting about 20 meteors per hour across the night sky.
This meteor shower happens when Earth travels through the debris trailing behind Halley’s Comet and it burns up in our atmosphere.
The full duration of the meteor shower stretches from September 26 to November 22, but your best bet to see meteors is on October 21 before midnight until around 2 am.

This is because, not only is this night the shower’s peak, it is also the October new moon, meaning the moon will be between the Earth and the Sun, making it dark and invisible to us.
With a moonless sky, you’re much more likely to catch a fireball careening through the night.
So find a dark location after the sun has set, look to the southeast sky (if you’re in the northern hemisphere) and the northeast (if you’re in the southern hemisphere) and enjoy!
Orionid meteors appear to come from the direction of the Orion constellation but you might catch them all across the sky.

Good morning, readers, and happy Friday. Welcome to This Week in Space, our Friday morning roundup of the week’s most important space news. Today we’ve got a bunch of good news, including a newfound exoplanet and a dozen new moons orbiting Jupiter. We’ve also got a report of an absolutely wild idea — a literal moonshot — for fighting climate change with moon dust.
SpaceX Starship Aces Static Fire Test
Thursday afternoon, SpaceX ran a successful static fire test of its gigantic Starship rocket. With 33 separate Raptor engines, Starship has the most engines of any rocket ever. Together, their thrust is twice that of a Saturn V or the Space Launch System. Is anyone else amazed the struts can hold that thing on the gantry?
Only 31 of the 33 engines fired. However, that’s actually good news because it means Starship can handle multiple engine failures.
SpaceX hopes to attempt a test flight for Starship in March. “That first flight test is going to be really exciting. It’s going to happen in the next month or so,” said Gwynne Shotwell, SpaceX’s president and chief operating officer.
“We will go for a test flight and we will learn from the test flight and we will do more test flights,” Shotwell added. “The real goal is to not blow up the launch pad. That is success.”
ISS Astronauts Work On Plasma Crystals, Space Plumbing
We’ve talked about how the folks aboard the International Space Station have to become polymaths to keep up with the demands of life in orbit. This winter, among many other pursuits, NASA astronauts on the ISS have been tending tomatoes and working on avant-garde methods of space propulsion. But the most recent projects in low-earth orbit make space tomatoes sound outdated. Over the past few days, crew on the ISS have been working on plasma crystals, servicing jetpacks, and… doing space plumbing.
NASA astronaut Frank Rubio and JAXA astronaut Koichi Wakata spent Thursday doing maintenance on the station’s water recovery system and orbital plumbing for the station’s bathroom, respectively. Meanwhile, station commander Sergey Prokopyev worked inside the Columbus lab “configuring video hardware that records how clouds of highly charged particles, or plasma crystals, behave in microgravity.”
Hubble Captures New Portrait of Tarantula Nebula
The Tarantula Nebula is the brightest star-forming region in our cosmic neighborhood. It’s not even in our galaxy — it’s in the Large Magellanic Cloud, one of the Milky Way’s satellite galaxies. But it’s so bright that it dazzles even at that distance. Astronomers recently used the Hubble space telescope to capture this image of the Tarantula Nebula in all its splendor:
What you see here is actually a joint effort between two different astronomy projects. One team sought to analyze the properties of dust grains floating between stars — a proposal dubbed Scylla by the Hubble team. Those dust grains create the dark, wispy clouds spread across the frame. The other, called Ulysses, studies interstellar dust and starlight interactions.
Curiosity Finds Clues to Mars’ Watery Past
NASA’s Perseverance rover went to Mars with a plan: Scour the planet’s surface for evidence that can teach us about Mars’ history and tell us whether the Red Planet might once have supported life. During its two years on Mars, the rover has found silicate clay and other minerals, signs that liquid water once flowed across Mars’ surface. But none of its discoveries have had evidence of water as visually obvious as a photograph that the agency’s Curiosity rover recently captured. The rover caught a photo of sandstone rock with ripples carved out of its surface, showing that the rock was once at the bottom of a lake.
The ripples support our observations of Mars’ weather and climate. Gentle, constant winds create standing ripple patterns like these. This fits with the constant prevailing winds and planetwide dust storms we’ve seen on Mars. It’s also exciting evidence that Mars indeed had liquid water once upon a time.
Russia Launches Progress Spacecraft to International Space Station
Russia successfully launched a Progress capsule aboard a Soyuz rocket this week, bound for the International Space Station. The rocket launched from Russia’s Baikonur aerodrome early Thursday morning, local time. This capsule, ISS Progress 83 (83P), carries about three tons of supplies, including food, water, and air. It will dock with the Russian Zvezda module on Saturday morning, replacing the Progress capsule that left Monday afternoon.
What happens to Progress 82 once it departs? Progress capsules are expendable. This means that the crew on the ISS loads the capsules with trash from the station while it’s docked. Then, hours or days after the capsule undocks, it burns up in the atmosphere.
CAPSTONE Lunar Satellite Reports In After 11-Day Glitch
NASA’s CAPSTONE satellite is finally responding to hails after nearly two weeks incommunicado. A software glitch left the probe unresponsive on Jan. 26 until it rebooted itself Monday.
“The spacecraft remained overall healthy and on-course throughout the issue,” NASA said in a blog post. “On Feb. 6, an automatic command-loss timer rebooted CAPSTONE, clearing the issue and restoring two-way communications between CAPSTONE and the ground.”
The satellite has made twelve successful circuits in its near-rectilinear halo orbit (NRHO) — twice what its original mission expected. That’s great news for NASA. CAPSTONE is trying out the fancy new NRHO orbit because it’s more fuel efficient than other lunar orbits we’ve used. In twelve orbits, CAPSTONE has only had to fire its engine twice. This smashing success means the agency may use the new orbital pattern for lunar support satellites under the aegis of its Artemis project.
Rolls-Royce Building Nuclear Engine For Spaceships
Did you know Ball makes Mason jars — and parts for space telescopes? Ball made parts for Hubble and the mirrors for the JWST. In a similar fashion, Rolls-Royce appears to be branching out. Way out. The luxury automaker’s subsidiary, Rolls-Royce Holdings, has announced plans to build a nuclear engine for deep space exploration.
Webb Telescope Breaks Own ‘Speed Limit’ Tracking DART Impact
NASA’s Guaranteed Time Observation program gives a certain amount of telescope time to those who worked on the JWST. One GTO project: Making observations of NASA’s DART kinetic asteroid redirect test. However, the project brought an unlooked-for surprise. Wednesday, JWST deputy project scientist Stefanie Milam explained how the telescope broke its own speed limit watching the asteroid impact.
Webb launched with the ability to track objects moving through the sky as fast as Mars. But scientists who study fast-moving small bodies like asteroids, comets, and interstellar objects “really wanted to study objects that moved faster than Mars,” said Milam. So, the team set out to show that not only could Webb exceed this “notional speed limit,” it could go much faster. Their efforts paid off when it came time to observe the DART asteroid impact.

The video Webb captured of the Dimorphos impact showed that the telescope can move its field of regard at more than triple its original maximum speed. Most of the time, though, Milam says the telescope will confine itself to double its original turning speed. Darn.
Chris Hadfield Meets With King Charles III
On Thursday, Canada’s favorite astronaut, Chris Hadfield, met with King Charles III at Buckingham Palace. The two sat down to discuss “efforts to encourage sustainability in space,” according to the Royal Family’s official Twitter.
“What a pleasure and privilege to be asked to advise and assist, and make the King laugh,” Hadfield wrote afterward.
While we don’t yet have specifics, Charles is a longtime environmentalist. Could it be that the King is interested in cleaning up space junk?
A Shield of Lunar Dust Could Help Cool Earth
Astrophysicists are pondering the pros and cons of a literal moonshot to blunt the effects of climate change. In a recent study, a group of researchers proposed launching moon dust into orbit around Earth to create a dusty shield that would reduce Earth’s exposure to the Sun. Evidently, lunar dust grains are just the right size and composition to block some of the solar energy that would hit the Earth.
For six days out of the year, the researchers say, the dust cloud would shield Earth from a few percent of the Sun’s radiation. To carry out this plan, the researchers’ numbers require dredging up some 22 billion pounds of lunar dust. They could fire the dust into orbit from the Moon or a platform in orbit — potato, poterrible idea. Surely there is some lower-hanging fruit?
Scientists Find a Dozen New Moons Orbiting Jupiter
In October 2019, astronomers at the Carnegie Institution for Science found 20 new moons orbiting Saturn. This made Saturn the “moon king” of the Solar System, with a total of 83. However, the same team has announced they’ve found a dozen new moons orbiting Jupiter.
An international team of astronomers has reported a newfound exoplanet in our cosmic backyard. The new planet, Wolf 1069 b, is between 1 and 1.4 Earth masses and just 8% bigger. Calling it Earth-like might be a stretch: Wolf 1069 b zips around its low-mass red dwarf star in just 15 Earth days. However, it’s just 31 light-years away.
Unlike our nearest neighbor, Proxima Centauri, Wolf 1069 doesn’t show the characteristic bursts of violent flares we frequently see in red dwarf stars. This could mean it has managed to retain an atmosphere. If so, the planet’s surface temperature could be about 55 degrees Fahrenheit. If not, it’s more likely an iceball, too cold to sustain liquid water.
Skywatchers Corner
Comet C/2022 E3 (ZTF) is a once-in-an-epoch visitor from the outer solar system. We haven’t seen it since the time of the Neanderthals, but it’s come back for one last visit. The outbound comet passed close to Earth last week. Now, it’s buzzing Mars.

The green comet will be near Mars in the constellation of Taurus for the next several days. After sunset, look high in the sky for the best shot at catching it through binoculars or a telescope. After Feb. 14, the comet will start heading toward Orion and Eridanus.
If you don’t have a good shot at viewing the comet where you are, you can still catch it online. This weekend, the Virtual Telescope Project is webcasting a free livestream of the comet’s approach to the Red Planet. The livestream will begin this Saturday, Feb. 11, at 2 p.m. EST (1900 GMT). You can watch it on the project’s website and YouTube channel.
