The objective of this observation is to determine the nature of a group of mounds, some of which have small pits at their summits. These features may be caused by ground ice melting and possibly turning into steam. They are barely visible in Context Camera image, so our camera’s resolution can help us to determine how they were formed.

​SUPER Conditions as Southern California's dry heatwave continues and brings with it some amazing seeing even at less than 40 degrees up. I was determined to get this shot and it was not easy but I pulled it off. If the target was higher I think it could have been more clear. I resized this image to 2500x2500 from roughly 300x300.

.

​HOW I DID THIS IMAGE:

Keeping my histogram at 30%. This keeps the Moons from blowing out. I focus the Moons. FPS 250 I shot consecutively 30 second shots and this is the maximum shot. You can appreciate how Io is in fact moving fast against Ganymede's surface background. This is because Io orbits much faster. On this capture, Io would appear to be the only one moving and both moons are moving in opposite directions.

Watching the sun is watching a magnetic field in action. Those fun science experiments we did in school with iron filings and a magnet is basically what we are seeing on the sun, but with more complexity.

The sun does not have one single north south magnetic poles, but many different ones scattered all over at varying strengths.

We can see how magnetism governs the churning atmosphere known as the chromosphere. A relatively thin layer where hydrogen alpha particles can be seen interacting with the fields being generated.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month features galaxies in incredible detail that have been warped and multiplied like they’ve stepped into a house of mirrors. The brilliant golden galaxies splashed across this image belong to a galaxy cluster called MACS J0454.1-0300. The orange galaxies concentrated on one side of the cluster are not actually part of the cluster; these galaxies are much farther away from us than the galaxies that make up MACS J0454.1-0300.

MACS J0454.1-0300 is itself incredibly distant: the light from these galaxies has been travelling to us for so long that we’re seeing the cluster as it was when the Universe was about 8 billion years old. While this galaxy cluster is a valuable scientific target in its own right, the real stars of this image are the galaxies that appear warped and stretched, like a painting that has been smeared by a giant hand.

These strange-looking galaxies are of immense interest to astronomers. The way these galaxies look is the result of gravitational lensing, in which the enormous mass of a foreground object such as a galaxy cluster bends and magnifies the light from a more distant object in the background. Gravitational lensing allows astronomers to observe galaxies, star clusters and even individual stars that are too far away for our telescopes to see under normal conditions. While the large, orange galaxies appear obviously distorted, look carefully at some of the small reddish background galaxies throughout this picture: even at the very edges of the frame, there are galaxies whose images have been bent into tiny arcs by MACS J0454.1-0300’s gravity.

From HiWish: “These dunes are situated right beneath steep tall slopes and are also part of an environment on Mars that is rather unique (the Hellas basin). The purpose of this observation is to see if the dunes located here have significant differences compared to dunes elsewhere on Mars due to the special environment.”

Starship returns to Earth; rocket splashes down north of Hawaii after three-hour flight

.

With thirteen suborbital test flights behind them, SpaceX engineers launched the company’s Super Heavy-Starship on its first flight to orbit Monday, a major step toward perfecting the world’s most powerful rocket for commercial flights and NASA moon missions.

One of the Starship upper stage’s six Raptor engines shut down early during the climb to an initially suborbital trajectory. After assessing telemetry, Elon Musk’s flight control team decided the spacecraft was otherwise healthy and a second engine firing using a single Raptor engine completed the climb to orbit.

Right after that, the Starship upper stage deployed 26 third-generation Starlink internet satellites that will join the company’s ever growing constellation in the first use of the new rocket to launch operational satellites in low-Earth orbit.

After the satellites were away, SpaceX controllers opted to bring the Starship back to Earth well ahead of schedule, ending the mission three hours after launch with a Pacific Ocean splashdown north of Hawaii.

.

.

For NASA, getting the Starship into orbit and back were critical steps on the road to perfecting the system in time to support a planned Artemis moon landing, using a variant of the Starship, in 2028.

A future moon mission will require multiple Super Heavy-Starship tanker flights to fuel the lander for its flight to the moon before docking with a NASA Orion crew capsule in lunar orbit, picking up two astronauts and carrying them down to the surface and back.

“Congrats SpaceX!,” NASA Administrator Jared Isaacman said in a post on the social media platform X. “Gorgeous launch, getting Ship to orbit and managing every step in a safe, responsible, and especially inspirational way. NASA, along with the rest of the interested public, is excited to help where we can and for Starship missions to become routine!”

Few doubt SpaceX will eventually get the Super Heavy-Starship flying reliably, but it’s not yet known whether the company will be able to meet NASA’s ambitious 2028 target date for the Artemis IV moon landing.

In any case, Monday’s mission got off to a spectacular start. The Super Heavy booster’s 33 methane-burning Raptor engines ignited with a rush of flame at 8:49 a.m. EDT, quickly propelling the 400-foot-tall rocket away from SpaceX’s Starbase launch site on the Texas Gulf Coast.

.

.

The Super Heavy first stage booster, generating some 16 million pounds of thrust — twice the power of NASA’s Space Launch System moon rocket — rapidly accelerated as it consumed propellant and lost weight, climbing out of the thick lower atmosphere along a southeasterly trajectory. One of the engines shut down early, but the rocket was designed to reach space despite the loss of a few engines.

Two minutes and 20 seconds after liftoff, the rest of the first stage engines began shutting down while the six Raptors powering the Starship upper stage began firing up in a “hot staging” maneuver seconds before the the booster separated and fell away.

While the Starship continued toward space, the Super Heavy booster flipped around, restarted its engines to reverse course and then flew itself back to the Texas Gulf Coast. A second engine apparently shut down early during the so-called boost-back burn, but the huge rocket was able to execute a seemingly normal vertical splashdown a few miles off shore.

During the most recent previous test flight, three engines suffered problems that prevented a full-duration boost-back burn and only eight of 13 engines fired for the landing burn. The result was a “hard” splashdown. SpaceX implemented multiple upgrades and software changes to ensure a successful return this time around.

The first stage is designed to be captured by giant mechanical arms on its launch gantry, a feat SpaceX has accomplished four times to date. But until upgrades and improvements have been tested, SpaceX has opted to stick with ocean splashdowns as a safety precaution. The Starship upper stage also is designed to be captured back at the pad after a trip to space and back, but that milestone has not yet been attempted.

The Starship upper stage launched Monday climbed into a 180-mile-high orbit with two engine firings. The first, ending a minute or so after the booster’s splashdown, was intended to put the Starship onto a sub-orbital trajectory similar to past flights that would result in a safe splashdown even if SpaceX lost control of the rocket.

Despite the premature shutdown of one engine, the Starship was cleared to proceed with the orbit-insertion burn and eight-and-a-half minutes after that, a Pez-like dispenser in the rocket’s nose began launching 26 third-generation Starlink internet satellites, each with 10 times the capacity of the previous generation.

The mission was initially expected to last six orbits, leading to a splashdown off the coast of Chile around 6:40 p.m. But with the Starlink satellites safely on their way, mission managers opted to bring the ship down early with a Pacific Ocean splashdown north of Hawaii.

SpaceX launches Starship into orbit for 1st time — largest rocket ever built notches key milestone on dramatic Flight 14 test

.

SpaceX's Starship and Super Heavy megarocket — the biggest and most powerful launch vehicle ever built — reached orbit today (Sept. 28), notching a huge milestone on the road to operational flight. But the launch, from SpaceX's Starbase site in South Texas, was not without high drama.

During liftoff, one of the six engines on Starship's Ship upper stage went out, raising doubt about whether SpaceX would attempt to reach orbit after all. SpaceX spokesperson Dan Huot even announced it was called off, only to reverse course as flight controllers decided to press ahead.

.

The rocket of the future

Starship stands 407 feet (124 meters) tall and can haul more than 110 tons (100 metric tons) to Earth orbit, according to its SpaceX specs page. The rocket's Super Heavy booster and Ship upper stage are both designed to be fully and rapidly reusable.

SpaceX thinks this combination of power and reflight will be transformative, allowing humanity to expand its footprint into the final frontier like never before. For example, Elon Musk has repeatedly cited Starship's potential to make Mars settlement economically feasible.

Heads up: a large filament just lifted off near the Sun's western limb. Most of it is heading away from Earth, but some of the material looks to have twisted around and may be directed along the Sun-Earth line. We'll see how much may be aimed towards us as we get more data...
