Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738.. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from Earth with help from a telescope.
The U.S. space agency's Artemis program aims to put astronauts in the coming years on the lunar surface for the first time since 1972 in preparation for potential future human missions to Mars.
A star system known as "V Sagittae" is expected to go nova this year (+/- 11 years). 2084 November 10 Transit of Earth as seen from Mars, the first and the only one in this century. 2085 November 7 Transit of Mercury: 2088 October 27 Mercury occults Jupiter for the first time since 1708, but very close to the Sun and impossible to view with the ...
1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
These observations are the closest scientists have come to finding evidence of liquid water on the planet's surface today. [14] [23] Frozen water, however, has been detected near the surface in many middle to high-latitude regions. Purported droplets of brine also appeared on struts of the Phoenix Mars Lander in 2008.

According to Star Walk, an astronomy app and developer, Venus, Mars, Saturn and Neptune will be visible. While full planetary alignments are rare, the alignment or three to six planets happens often.
Mars atmospheric entry is the entry into the atmosphere of Mars. High velocity entry into Martian air creates a CO 2 -N 2 plasma, as opposed to O 2 -N 2 for Earth air. [ 1 ] Mars entry is affected by the radiative effects of hot CO 2 gas and Martian dust suspended in the air. [ 2 ]
Another year has come and gone, which means it’s once again time to get cozy on your couch and watch the ball drop (or watch When Harry Met Sally for the hundredth time, we won’t judge).
