This week’s image shows the Artemis II crew – NASA Commander Reid Wiseman, NASA Pilot Victor Glover, NASA Mission Specialist Christina Koch, and Canadian Mission Specialist Jeremy Hansen. It looks like a movie poster, which makes sense given that it is one of the better shows this year and lasts for 10 days.
You can find this poster and many others on the NASA images website.
You can follow the status of the mission on the main NASA page for the duration of the mission (shown below).
This week’s images of Saturn from 2024 were just released by NASA. They show the planet in a variety of ways, depending on the telescope and instruments being used. The James Webb Space Telescope (JWST or Webb) and Hubble Space Telescope each have their own unique abilities that can bring the distant gas giant to life.
In its comments on the two images above, NASA noted:
Together, scientists can effectively ‘slice’ through Saturn’s atmosphere at multiple altitudes, like peeling back the layers of an onion. Each telescope tells a different part of Saturn’s story, and the observations together help researchers understand how Saturn’s atmosphere works as a connected three-dimensional system. Both complement previous observations done by NASA’s Cassini orbiter during its time studying the Saturnian system from 1997 to 2017...These 2024 observations, taken 14 weeks apart, show the planet moving from northern summer toward the 2025 equinox. As Saturn transitions into southern spring, and later southern summer in the 2030’s, Hubble and Webb will have progressively better views of that hemisphere.
This week’s images come from the James Webb Space Telescope (JWST). Each image shows a different view of the Cranium nebula depending on the JWST instrument being used. It is also called the “Exposed Cranium” Nebula because it looks like a brain in a see-through skull.
Here is a little more from NASA on what you are seeing above:
The nebula appears to have distinct regions that capture different phases of its evolution — an outer shell of gas that was blown off first and consists mostly of hydrogen, and an inner cloud with more structure that contains a mix of different gases. Both Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) show a distinctive dark lane running vertically through the middle of the nebula that defines its brain-like look of left and right hemispheres. Webb’s resolution shows that this lane could be related to an outburst or outflow from the central star, which typically occurs as twin jets burst out in opposite directions. Evidence for this is particularly notable at the top of the nebula in Webb’s MIRI image, where it looks like the inner gas is being ejected outward.
The image above is from a NASA Office of the Inspector General audit report on the Human Landing System. It shows the complexity of the Blue Origin process for getting a crew on the Moon. It is complex, and has one more step than the SpaceX plan, which already seems close to impossible.
This is how the audit report explained the graphic you see above:
For the Artemis V mission, Blue Origin is developing its Blue Moon lander. Standing 52 feet tall, Blue Moon will launch on Blue Origin’s reusable New Glenn heavy-lift rocket from Cape Canaveral Space Force Station in Florida. The lander will utilize Blue Origin’s BE-7 engines, which are fueled by liquid oxygen and liquid hydrogen. Prior to the Artemis V mission, Blue Origin will launch a transporter to low Earth orbit, essentially serving as a propellant depot. From there a fleet of refuelers will launch, rendezvous with the transporter, and transfer propellant. The Blue Moon lander will then launch to low Earth orbit to receive fuel from both a refueler and the transporter before traveling to NRHO to dock with Gateway for the Lunar Orbit Checkout Review. The transporter, left in low Earth orbit, will receive additional propellant there before traveling to a higher “stairstep” orbit for final propellant aggregation.14 Once the transporter has traveled to NRHO, Blue Moon will undock with Gateway to receive its final propellant transfer and then dock with Gateway a second time. Next, Orion will deliver the astronauts to Gateway, who will then transfer to Blue Moon for transit to the lunar surface and back to the station. At the end of the mission, Orion will return the astronauts to Earth and the lander will transition to another orbit for disposal or later reuse.
This week’s image comes from the the European Space Agency (ESA). Captured by ESA’s orbiting Mars Express, you are looking at a portion of the crater-covered Arabia Terra, which is a large plain in Mars’s ancient highlands. You can read more about this Martian region by visiting this site.
Here is the ESA’s description of what you are viewing:
A high‑resolution overhead view of a rocky, desert‑like landscape on Mars. The surface is mostly reddish‑brown with patches of darker blue‑grey tones. Many circular impact craters of different sizes are scattered across the scene, some with raised rims and shadowed interiors. Subtle ridges, eroded valleys, and textured terrain patterns run diagonally through the image, giving a sense of ancient geological activity. The overall impression is of a dry, rugged, and heavily cratered Martian surface.
