Lunar scientists have started plotting out photographic objects of interest for the four-person Artemis 2 crew to consider during their flyby of the moon.
While ambitious plans to return Red Planet samples to Earth are in development, some scientists argue that we should instead find ways to analyze Mars samples on the planet itself.
NASA's Lunar Reconnaissance Orbiter recently bounced a laser off India's Vikram moon lander, marking a space-communications first.
Scientists are investigating the possible forms that alien languages might take — and whether we might be able to understand them.
NASA's Mars Sample Return program is the agency’s highest priority in planetary science, but projected multibillion-dollar overruns have some calling the plan a 'dumpster fire.'
Landing on the moon may soon be much easier thanks to NASA's Lunar Retroreflector Array network being carried to the lunar surface on international and commercial landers.
A new study has found that amino acids — the building blocks of proteins — remain stable in concentrated sulfuric acid, the stuff that Venus' clouds are made of.
Pittsburgh-based company Astrobotic is gearing up for the Jan. 8 launch of its Peregrine lander, which will try to become the first private spacecraft to land on the moon.

Russia kicked off another one of its simulated missions this week, this time a 360-day isolation of individuals to imitate flight conditions of a deep space journey.
While landing humans on the moon was indeed historic and the boot-kicked lunar dust has settled, perhaps that achievement had more of an impact on society than we realized.
Japan's planned Martian Moons eXploration (MMX) spacecraft mission involves drilling and sampling Mars' moon Phobos, then rocketing the samples to Earth.
NASA's Perseverance rover is scurrying around on the Red Planet, wheeling and dealing around Jezero Crater and inspecting the site of this former lake up close.
For many anxious to throw light on unidentified anomalous phenomena, it's all about reliable, truth-revealing, and scientifically rigorous data collection.
