Last summer, the Parker Solar Probe flew past Venus on its way to fly closer to the Sun. In a bit of a surprise, one of the spacecraft’s cameras, the Wide-field Imager for Parker Solar Probe, or WISPR, captured a striking image of the planet’s nightside from 7,693 miles (12380 km) away.
The surprise of the image was that WISPR – a visible light camera – seemingly captured the Venus’ surface in infrared light.

A secret coded message was hidden on the gigantic parachute used to land the Perseverance rover safely on the surface on Mars. And no, it wasn’t a clandestine message to the Martians. It was a message of inspiration for us humans.
But it also came as a challenge.

The HiRISE camera on the Mars Reconnaissance Orbiter has done it again.
The imaging team was able to capture the Perseverance rover as it descended through the Martian atmosphere, hanging under its parachute.

If the Roman Empire had been able to launch a satellite in a relatively high Low Earth Orbit – say about 1,200 km (750 miles) in altitude – only now would that satellite be close to falling back to Earth. And if the dinosaurs had launched a satellite into the furthest geostationary orbit – 36,000 km (23,000 miles) or higher — it might still be up there today.

They’ve done it again. After a journey of nearly seven months, the Perseverance rover teams successfully guided their intrepid traveler to a pinpoint landing inside Jezero Crater on Mars on February 18, 2021.
And within minutes of the landing, Perseverance sent back two images from the front and rear Hazard Avoidance Cameras, revealing its surroundings on the Red Planet.

One of the oldest, deepest, and largest impact craters on the Moon provides a window into the history and makeup of our celestial companion, and needs to be studied in more detail, says a team of lunar scientists. The South Pole-Aitken Basin on the Moon formed from a gigantic impact about 4.3 billion years ago. Scientists say a more detailed analysis of this area will help refine the timeline of events in the Moon’s development, as well as help explain the dramatic differences between the lunar nearside and farside.

When one of the Russian Progress resupply ships undocks from the International Space Station, timing is everything. The Progress needs to fire its engines at just the right time to instigate the deorbit burn in order for the ship to enter the atmosphere at just the right place, so that its destructive re-entry occurs over the Pacific Ocean. That way, any potential surviving bits and pieces that might reach Earth will hit far away from any land masses – which are home to people, buildings, and other things we don’t want to get bonked.

The words “snow” and “Hawai’i” are not often mentioned in the same paragraph – or even on the same vacation. But snow does fall in Hawai’i almost every year, and 2021 has seen a deep cold front drop snow on the summits of Mauna Loa and Mauna Kea on the Big Island at least three times in the past few weeks – as well as on Haleakala on Maui. This means there are currently in snowcaps on Hawai’i’s three tallest mountains.

Now that the UAE’s Hope spacecraft and China’sTianwen-1 have successfully reached the Red Planet, next up is NASA’s Perseverance rover, set to land on February 18th.
Ten operational spacecraft are currently in orbit or on the surface of Mars, ready to welcome the new rover. But one spacecraft in particular, the InSight lander, will be listening closely for Perseverance’s dramatic entry, descent and landing – a.k.a. the Seven Minutes of Terror.

50 years ago this week, the Apollo 14 crew flew their mission to the Moon. Alan Shepard and Edgar Mitchell were the third pair of astronauts to walk on the lunar surface. They conducted two moonwalks in the Fra Mauro highlands, collecting rocks and setting up science experiments, as well as broadcasting the first color TV images from the Moon.
Meanwhile, Stuart Roosa remained in orbit as the Command Module pilot. But Roosa wasn’t alone while circling above the Moon.
