Apollo 10’s “Snoopy” Lunar Lander May Have Been Found in Space

Apollo 11 was the first mission to land people on the lunar surface. But Apollo relied on a lot of predecessor missions to lay the groundwork for the successful mission to the Moon. One of them was Apollo 10, the fourth crewed mission in the Apollo program.

Apollo 10 was an almost complete mission that including everything that Apollo 11 had, except for an actual landing on the Moon. It was a dress rehearsal, and was the second Apollo mission to orbit the Moon. It even had an Apollo Lunar Module that was flown to within 15 km of the lunar surface. But that module never landed, and eventually, after it rendezvoused with the command module and the crew disembarked, it was sent into orbit around the Sun.

And up until now, nobody knew where it was.

It’s Been Exactly One Year Since Opportunity Sent This Final Message Home – on its 5,111th Martian Day

Opportunity’s final message home is not much to look at on its own. If you’re old enough to remember film cameras, it looks like the final exposure on a roll of film, developed but partly missing. It’s a suitable epitaph for Opportunity’s mission.

New Instrument is Searching for Planets Around Alpha Centauri

Alpha Centauri is the closest star system to us, at 4.37 light-years (about 25 trillion miles) away. In 2016, astronomers discovered an exoplanet orbiting one of the three stars in the Alpha Centauri system. Spurred on by that discovery, the European Southern Observatory (ESO) has developed a new instrument to find any other planets that might be in the Alpha Centauri system, and it’s busy looking right now.

That Explains a Lot. The Moon’s Largest Crater has a Chunk of Metal Embedded in it That’s 5 Times Bigger than the Big Island of Hawaii

One of the largest craters in the Solar System is on our Moon. It’s called the South Pole-Aitken (SPA) basin and it’s 2,500 km (1,600 mi) in diameter and 13 km (8.1 mi) deep. A new study says that the basin may contain an enormous chunk of metal that’s larger than Hawaii’s Big Island.

Perfect Example of a Barred Spiral Galaxy, Seen Face On. This is What Our Milky Way Might Look Like

This striking image was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3, a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble’s most breathtaking and iconic photographs, including Pictures of the Week. Shown here, NGC 7773 is a beautiful example of a barred spiral galaxy. A luminous bar-shaped structure cuts prominently through the galaxy's bright core, extending to the inner boundary of NGC 7773's sweeping, pinwheel-like spiral arms. Astronomers think that these bar structures emerge later in the lifetime of a galaxy, as star-forming material makes its way towards the galactic centre — younger spirals do not feature barred structures as often as older spirals do, suggesting that bars are a sign of galactic maturity. They are also thought to act as stellar nurseries, as they gleam brightly with copious numbers of youthful stars. Our galaxy, the Milky Way, is thought to be a barred spiral like NGC 7773. By studying galactic specimens such as NGC 7773 throughout the Universe, researchers hope to learn more about the processes that have shaped — and continue to shape — our cosmic home.

The Hubble Space Telescope has given us a beautiful image of the barred spiral galaxy NGC 7773. This is a classic galaxy of this type, and highlights the bright bar of concentrated stars that anchors the galaxy’s stately spiral arms. It was captured with the Hubble’s workhorse Wide Field Camera 3 (WFC3.)

NASA’s next mission to the surface of Mars is called the 2020 rover (in case you didn’t know already.) It’s planned launch date is July 17th, 2020, and it should land at Jezero Crater on Mars on February 18th 2021. The rover is still under construction at the Jet Propulsion Lab in Pasadena, California.

Don’t Worry About Asteroid 2006QV89. There’s Only a 1 in 7000 Chance It’ll Hit the Earth in September

Whenever scientists announce an upcoming close encounter with an asteroid, certain corners of the internet light up like the synaptic rush that accompanies a meth binge, with panicky headlines shouted straight from the brain stem. But never mind that. We’re not that corner of the internet. We’re sober, yo!

The ESA is developing its own spacecraft capable of re-entry into Earth’s atmosphere. The reusable spacecraft is called the Space RIDER (Reusable Integrated Demonstrator for Europe Return), and the ESA says that the Space Rider will be ready for launch by 2022. It’s being designed to launch on the Vega-C rocket from Europe’s spaceport in Kourou, French Guiana.

There’s a Ring of Cool Gas Wrapped Around the Milky Way’s Supermassive Black Hole

There’s a lot going on at the center of our galaxy. A supermassive black hole named Sagittarius A-Star resides there, drawing material in with its inexorable gravitational attraction. In that mind-bending neighbourhood, where the laws of physics are stretched beyond comprehension, astronomers have detected a ring of cool gas.

Engineers are Still Troubleshooting Why Mars InSight’s Mole is Stuck and Won’t Go Any Deeper

NASA’s Mars InSight Lander was always a bit of a tricky endeavour. The stationary lander has one chance to get things right, since it can’t move. While initially the mission went well, and the landing site looked good, the Mole is having trouble penetrating deep enough to fulfill its mission.
