The Soyuz MS-22 crew ship is pictured in the foreground docked to the Rassvet module as the International Space Station orbited 264 miles (425 kilometers) above Europe. In the background is the Prichal docking module attached to the Nauka multipurpose laboratory module. Both spacecraft are pointed toward Earth. Brown land masses are visible and cumulus clouds are scattered across the blue curvature of Earth. Credit: NASA

If you’ve been tuning in, you know landing on Mars is half of the battle–returning the first astronauts home from the Red Planet is the other half. Listen in as four experts discuss in this week's episode of “Houston, We have a Podcast”: go.nasa.gov/42FdMN9

Newly-discovered asteroid 2023 DZ2 will sail safely past Earth today. Asteroids pass our planet safely all the time, but a close approach by one of this size (140–310 ft, or 43–95 m) happens only about once per decade. (There is no known threat for at least the next 100 years.)

First light data from the NASA-
@CNES
SWOT mission reveals that it provides 10 times the resolution of ocean measurements than data gathered by seven other satellites combined. These measurements will help us better study Earth’s surface water. go.nasa.gov/3z5hIJj
Sea level data gathered Jan. 21 in the Gulf Stream by SWOT’s KaRIn instrument. The ocean is grey and the land is white, showing the coastlines of Virginia and North Carolina. A data overlay, generated from SWOT’s measurements, shows up as a colorful stripe on the right side of the image. A color code at the bottom of the image shows that color in the data stripe corresponds to sea surface height anomaly in meters, where dark blue is less than or equal to 0.25, white is 0, and dark red is greater than or equal to 0.25.

Sea level data generated from 7 active nadir altimeter missions shows up as a colorful stripe that is fuzzier than the first image. A color code at the bottom of the image shows that color in the data stripe corresponds to sea surface height anomaly in meters, where dark blue is less than or equal to 0.25, white is 0, and dark red is greater than or equal to 0.25.

The Lockheed Martin X-33 X-plane, shown in this artist’s rendering, was intended to demonstrate technology pioneered under NASA’s Reusable Launch Vehicle program in the 1990s. The program was cancelled in 2001, but an emissive heat shield coating invented at Ames Research Center under the initiative has since found widespread commercial success as the Emisshield product line. The triangular white and black spacecraft is visualized flying through the atmosphere with a large emission of flame from its thruster. Credits: NASA

Around 2000, two ceramic tiles – one treated with an early version of Emissield and one untreated – were subjected to an oxyacetylene torch. The untreated tile, left, started beading after 30 seconds, while the one with the paper-thin layer of protection showed little damage after two minutes. Credits: NASA

may have found sand particles in the atmosphere of planet VHS 1256 b, which orbits a pair of stars 40 light-years away. Webb also detected water, carbon monoxide, and methane. Get the gritty details: go.nasa.gov/3lDePfN
Illustration of a planet orbiting far from its pair of host stars. The atmosphere appears orange and turbulent with swirling clouds, and it even has a cyclonic storm resembling Jupiter's Great Red Spot. Researchers detected both brighter and darker cloud patches, indicating some clouds are lower and hotter or higher and cooler than others, respectively. This illustration is based on observations from Webb. The camera that is part of Webb’s Near Infrared Spectrograph’s integral field unit does not have the resolution to capture the planet in detail at this distance.

Where will you be during the eclipses in 2023 and 2024? This map shows the path of the Moon’s shadow as it crosses the contiguous U.S. during the eclipse on Oct. 14, 2023 and total solar eclipse on April 8, 2024. Will you get a chance to see them? go.nasa.gov/40pj5hL
This map illustrates the paths of the Moon’s shadow across the U.S. during two upcoming solar eclipses. On October 14, 2023, an annular solar eclipse will cross North, Central, and South America creating a path of annularity. An annular solar eclipse occurs when the Moon passes between the Sun and Earth while at its farthest point from Earth. On April 8, 2024, a total solar eclipse will cross North and Central America creating a path of totality. During a total solar eclipse, the Moon completely blocks the Sun while it passes between the Sun and Earth. The sky will darken as if it were dawn or dusk and those standing in the path of totality may see the Sun’s outer atmosphere (the corona) if weather permits.

When we plan missions to send science off Earth, we have to prepare for inhospitable circumstances like acid clouds or extreme heat. Discover how we design spacecraft to travel through dangerous environments in this episode of the Curious Universe podcast: go.nasa.gov/42wtU3c
The Curious Universe podcast logo is in the middle of the image. On the left are lines radiating outward like spokes on a wheel; the chemical formulas for phosphorus trioxide (P4O6), hydrogen sulfide (H2S), and an iron silica compound (FeSiO2); three atom models of xenon; and a topographical map. On the right is an illustration of a yellow, orange, and brown landscape. The entire image is shown in shades of yellow and orange.

When Irish skies are smiling... This cloud-free view of Ireland, the Emerald Isle, was captured from space by our Aqua satellite back in 2010. Happy #StPatricksDay!
A vertically-oriented image of Ireland, as seen from space. The photo is almost completely free of clouds, except for a few wisps in the bottom-left, so the lush greens of the island stand out against the dark-blue water surrounding it.

Recent volcanic activity has been observed on Venus for the first time. Scientists made the discovery by poring over archival radar images of Earth’s twin taken in the '90s by our Magellan mission. Our VERITAS mission is set to investigate: go.nasa.gov/3mP5f9O
A computer-generated 3D image shows the entirety of Venus in a bright yellow color. There are patches of darker yellows that illustrate differences in the surface. The large circular planet has a black square to the middle-right section marking where volcanic activity was spotted in archival radar images from NASA's Magellan mission.
