Clouds on Mars are similar to those on Earth

One of the things that makes Mars loom large in our imaginations is just how Earth-like the planet is. For example, Mars has clouds that at least look like those seen on Earth.

Details: According to NASA, the clouds can be found about 19 miles high and are likely composed of water ice, making them similar in concept at least to cirrus clouds here on Earth, though those are typically found at about 6 miles up.

Also, Earth's atmosphere is far more hospitable compared to Mars.

The air on Mars is thinner than Earth's, containing mere traces of oxygen and an abundance of carbon dioxide.

The big picture: NASA researchers are trying to gain new insights into Mars' clouds by coordinating pictures between the navigation cameras on Curiosity and NASA's InSight lander, which is about 370 miles away on the red planet's surface. "Capturing the same clouds from two vantage points can help scientists calculate their altitude," NASA said.

New York City Mayor Bill de Blasio told a news conference Tuesday of plans to triple hospital bed numbers to combat the novel coronavirus by transforming facilities into makeshift hospitals — including U.S. Open tennis courts.

The big picture: The city now accounts for a quarter of all COVID-19 deaths in the U.S. — more than 1,000 as of Wednesday morning. De Blasio said the city had "about 20,000 working hospital beds in our major hospitals" before the outbreak. "We now need to, in just the next weeks ... produce three times that number," he said.

The novel coronavirus has now killed more than 4,000 people in the U.S. — with over 1,000 deaths reported in New York City alone, per Johns Hopkins data. The number of deaths are still much lower than those reported in Italy, Spain and China.

Of note: Hours earlier, President Trump noted it's "going to be a very painful two weeks," with projections indicating the novel coronavirus could kill 100,000–240,000 Americans — even with strict social distancing guidelines in place. "They are going to be facing a war zone," he said of medical workers.
