Meteorites are striking gold among collectors, with a dilapidated dog house that survived a hit from outer space expected to fetch up to $300,000 at a Christie’s auction, and a chunk of Mars going for as much as $800,000.
Bids are soaring for lots in “Deep Impact: Martian, Lunar and other Rare Meteorites” at a time when space is the limit, with the launch of SpaceX, the world’s first all-private space crew, and “Don’t Look Up,” the Oscar-nominated film about a comet speeding toward Earth.
The online-only sale of 66 lots ending on Wednesday includes “meteorites containing the oldest matter humankind can touch,” Christie’s said in a statement.
Items include “rocks that have been jettisoned by larger meteorite impacts on the moon or on Mars,” astrophysicist Neil DeGrasse Tyson said in an interview. “These rocks escaped, those bodies wandered through space, some of which landed here on Earth.”
The top price is expected to go to the third largest Mars rock on Earth. But the quirkiest item up for grabs since the auction opened on Feb. 9 is a doghouse.
The kennel’s resident Roky, a German Shepard, was inside and narrowly escaped when a meteorite crashed through the tin roof in April 2019 in Aguas Zarcas, Costa Rica.
“A seven-inch hole marks where the meteorite punctured the roof,” Christie’s said in the treasure’s description.
“He was almost nailed by a meteorite. Gratefully, that was not the case,” said Darryl Pitt, curator of the Macovich Collection of Meteorites, a consultant for the auction.
A meteor-struck cow in Venezuela in 1972 was not so fortunate. Its remains were butchered by a farmer and eaten.
So far, humans have been spared. And, while fiery crashing meteorites may be terrifying, they actually are commodities in an industry known as the meteorite trade, Tyson said.
“You might go your whole life without ever touching a meteorite, but there are people who have devoted their entire careers to finding them in the wild, and they often go up for sale either to merchants or at an auction,” Tyson said.
“So, if you want a piece of the universe other than Earth, they’re available to you.”
Tyson sees no shortage of those precious prizes from outer space now or in the near future.
“There’s probably many more tons of Moon meteorites and Mars meteorites scattered on Earth than are currently in our collections,” Tyson said.
“In a way, the universe is coming to us.”

See Astronaut's Sublime Shot of Total Lunar Eclipse Snapped From the ISS – CNET
Earthlings on Earth weren’t the only ones whothe lovely blushing of the “flower blood moon” total lunar eclipse on Sunday night and Monday morning. Residents of the International Space Station had a great view of the spectacular celestial event.
European Space Agency astronaut Samantha Cristoforetti shared a beautiful series of photos of the eclipse as seen from orbit. “A partially eclipsed moon playing hide-and-seek with our solar panel,” Cristoforetti tweeted on Monday.
The photos show the eclipse in progress, with the moon peeking under the station’s solar panels. One stunning view also shows Earth below, clouds visible against an expanse of blue. The images highlight the subtle shading of the moon as our planet threw its shadow across it.
Cristoforetti shared another look with just the eclipsed moon peeking over the curve of Earth.
Cristoforetti is an accomplished space photographer, having snapped plenty of gorgeous images during her last stay on the ISS in 2014 and 2015. Her most recent stint started in late April as part of launched by SpaceX.
I watched the eclipse last night from New Mexico. As the shadow moved across the moon, the ISS flew over, a bright bead of light crossing against the starry sky. So as I was seeing the ISS, Cristoforetti was likely tracking the eclipse, too. It doesn’t matter whether you’re on the ground or up in orbit,.
NASA's InSight still hunting marsquakes as power levels diminish – Phys.org
Dusty solar panels and darker skies are expected to bring the Mars lander mission to a close around the end of this year.
NASA’s InSight Mars lander is gradually losing power and is anticipated to end science operations later this summer. By December, InSight’s team expects the lander to have become inoperative, concluding a mission that has thus far detected more than 1,300 marsquakes—most recently, a magnitude 5 that occurred on May 4—and located quake-prone regions of the Red Planet.
The information gathered from those quakes has allowed scientists to measure the depth and composition of Mars’ crust, mantle, and core. Additionally, InSight (short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) has recorded invaluable weather data and studied remnants of Mars’ ancient magnetic field.
“InSight has transformed our understanding of the interiors of rocky planets and set the stage for future missions,” said Lori Glaze, director of NASA’s Planetary Science Division. “We can apply what we’ve learned about Mars’ inner structure to Earth, the Moon, Venus, and even rocky planets in other solar systems.”
InSight landed on Mars Nov. 26, 2018. Equipped with a pair of solar panels that each measures about 7 feet (2.2 meters) wide, it was designed to accomplish the mission’s primary science goals in its first Mars year (nearly two Earth years). Having achieved them, the spacecraft is now into an extended mission, and its solar panels have been producing less power as they continue to accumulate dust.
Because of the reduced power, the team will soon put the lander’s robotic arm in its resting position (called the “retirement pose”) for the last time later this month. Originally intended to deploy the seismometer and the lander’s heat probe, the arm has played an unexpected role in the mission: Along with using it to help bury the heat probe after sticky Martian soil presented the probe with challenges, the team used the arm in an innovative way to remove dust from the solar panels. As a result, the seismometer was able to operate more often than it would have otherwise, leading to new discoveries.
When InSight landed, the solar panels produced around 5,000 watt-hours each Martian day, or sol—enough to power an electric oven for an hour and 40 minutes. Now, they’re producing roughly 500 watt-hours per sol—enough to power the same electric oven for just 10 minutes.
Additionally, seasonal changes are beginning in Elysium Planitia, InSight’s location on Mars. Over the next few months, there will be more dust in the air, reducing sunlight—and the lander’s energy. While past efforts removed some dust, the mission would need a more powerful dust-cleaning event, such as a “dust devil” (a passing whirlwind), to reverse the current trend.
“We’ve been hoping for a dust cleaning like we saw happen several times to the Spirit and Opportunity rovers,” said Bruce Banerdt, InSight’s principal investigator at NASA’s Jet Propulsion Laboratory in Southern California, which leads the mission. “That’s still possible, but energy is low enough that our focus is making the most of the science we can still collect.”
If just 25% of InSight’s panels were swept clean by the wind, the lander would gain about 1,000 watt-hours per sol—enough to continue collecting science. However, at the current rate power is declining, InSight’s non-seismic instruments will rarely be turned on after the end of May.
Energy is being prioritized for the lander’s seismometer, which will operate at select times of day, such as at night, when winds are low and marsquakes are easier for the seismometer to “hear.” The seismometer itself is expected to be off by the end of summer, concluding the science phase of the mission.
At that point, the lander will still have enough power to operate, taking the occasional picture and communicating with Earth. But the team expects that around December, power will be low enough that one day InSight will simply stop responding.

Peek-a-Boo Moon: Astronaut on Space Station Captures Spectacular Photos of the Lunar Eclipse – SciTechDaily
On the evening of May 15, 2022, Earth passed between the Sun and the Moon blocking sunlight and casting a shadow on the lunar surface. ESA astronaut Samantha Cristoforetti witnessed this lunar eclipse from the International Space Station and captured it in a series of photographs.
During a lunar eclipse, Earth’s atmosphere scatters sunlight. The blue light from the Sun scatters away, and longer-wavelength red, orange, and yellow light pass through, turning our Moon red.
In these images, the Moon appears to play hide and seek with one of the International Space Station’s solar panels:
