Mars Orbiter Captures Rare View of Ancient Volcano Poking Above the Clouds

One of Mars' tallest volcanoes peeps over a thick layer of clouds, in Odysseyβs first picture of Arsia Mons peering over the Red Planet's horizon.
I'm incredibly excited, as part of the Ars Live series, to host a conversation with three of the very best space reporters in the business on Thursday, May 29, 2025, at 3 pm EDT about the future of NASA and its deep space exploration ambitions.
Joining me in a virtual panel discussion will be:
The community of professional space reporters is fairly small, and Chris, Loren, and Joey are some of my smartest and fiercest competitors. They all have deep sourcing within the industry and important insights about what is really going on.

On Tuesday afternoon, just a few hours before a launch attempt of the ninth flight test of SpaceX's Starship vehicle, Elon Musk spoke with Ars Technica Senior Space Editor Eric Berger to talk about where his space company goes from here.
In recent weeks, Musk has dialed back his focus on politics and said he wants to devote the majority of his time to SpaceX and his other companies. So what does that mean?
The conversation came just ahead of the opening of Starship's launch window, at 6:30 pm CT (23:30 UTC) in South Texas. Here is a lightly edited transcript of the interview.

The Billboard Hot 100 is widely considered to be the definitive all-genre singles chart in the US.
Since it was launched in 1958, well over 1,000 songs have reached the coveted No. 1 spot, but far fewer have reigned long enough to reach double-digit weeks β or, even more impressively, surpass that milestone.
According to Billboard, only 4% of all No. 1 hits have topped the Hot 100 for 10 weeks or more. All 46 songs that have achieved the feat are listed below, in chronological order.
