Tiny cobbles on Mars

Tiny cobbles on Mars

Our second cool image takes us from grand galaxies, one of the universe’s largest coherent objects, to tiny cobbles on Mars. The picture to the right, taken by one of Perseverance’s close-up cameras on September 29, 2022, covers an area less than an inch across, making the largest rounded pebbles in this image only a few millimeters in size.

The rover presently sits on the floor of Jezero Crater, at the base of the delta that flowed into that crater eons ago. The data suggests that delta was created by flowing water entering a lake that filled the crater.

Did flowing water create these cobbles? These pebbles all have the look of the rounded cobble one finds either in river beds, or in glacial moraines. In both cases, the flow of the water or ice rolls the rocks along until they become rounded.

Interacting galaxies

9:02 am

Interacting galaxies
Click for full image.

The news is light this morning, so this cool image will be the first of three. The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today. From the caption:

The two interacting galaxies making up the pair known as Arp-Madore 608-333 seem to float side by side in this image from the NASA/ESA Hubble Space Telescope. Though they appear serene and unperturbed, the two are subtly warping one another through a mutual gravitational interaction that is disrupting and distorting both galaxies.

I did a search for any research of this galaxy pair, and found that its identification was only part of a larger survey, with only a little research done on its spectroscopy. Thus, I can’t tell you the size or distance, or how far apart from each other these galaxies lie.

Sunspot update: Activity again exceeds prediction but ramp up pauses

11:29 pm

NOAA this weekend published, as it does at the start of every month, its October update of its monthly graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. As I have done since I started this website in 2011, I have published that graph below, with some additional details added to provide context.

An increase in sunspot activity in September wiped out the decline seen in August, so that the sunspot number in September once again matched or exceeded the numbers seen during the middle of the previous solar maximum from 2012 to 2014, a low period of activity between that maximum’s two peaks. Activity also continued to exceed the predictions of the panel of government solar scientists put together by NOAA.

At the same time, since May the ramp up to maximum has stalled, something I noted last month and has now become more evident.

India’s Mars orbiter mission ends after eight years

6:17 pm

After eight years in orbit around Mars, India’s Mars orbiter mission, Mangalyaan, has run out of fuel for controlling its orientation, ending its mission.

The Rs 450 crore Mars Orbiter Mission was launched onboard PSLV-C25 on November five, 2013, and the MOM spacecraft was successfully inserted into Martian orbit on September 24, 2014 in its first attempt. “Right now, there is no fuel left. The satellite battery has drained,” sources in the Indian Space Research Organisation (ISRO) told PTI. “The link has been lost”.

There was, however, no official word from the country’s national space agency, headquartered here.

During its mission it produced more than a thousand images, though the mission’s primary objective was technological, proving that India itself could design, build, launch, and manage a planetary mission to another world. For India, Mangalyaan was thus an unqualified success.

Fabric debris spotted on Ingenuity during 33rd flight

10:19 am

Tattered fabric debris on Ingenuity's leg during flight
Click to see full movie of flight.

In reviewing the images from Ingenuity’s 33rd flight on September 24, 2022, engineers have spotted what looks like a tattered piece of fabric fluttering on the end of one of the helicopter’s legs, and then disappearing.

The image to the right, cropped, enhanced, and labeled to post here, comes from an animation created from all images taken during the flight.

A small piece of foreign object debris (FOD) was seen in footage from the Mars helicopter’s navigation camera (Navcam) for a portion of its 33rd flight. This FOD was not visible in Navcam footage from the previous flight (32). The FOD is seen in Flight 33 Navcam imagery from the earliest frames to approximately halfway through the video, when it fell from the leg and drifted back to the Mars surface.

The engineers do not yet know what this was, but it apparently caused no harm to the helicopter. It also is likely not from either Ingenuity or Perseverance, as both are functioning perfectly. Most likely it is a piece of the parachute used during landing and then ejected.

Head of Commerce’s space office questions new FCC regulations on space junk

10:00 am

Turf war! At a conference yesterday Richard Dalbello, director of the Office of Space Commerce at the Commerce Department, strongly questioned the FCC’s legal authority for its just passed new regulation on the de-orbiting of space junk.

“I think the FCC, for their part, has pushed the boundaries of their authorities pretty aggressively,” he said when asked about what agency should have oversight for issues like that, as his office works to create a civil space traffic management capability. “Although I certainly congratulate them on the depth of their intellectual work,” he said of the FCC and its new order, “a lot of the things that they articulated are probably, arguably, outside their job jar.”

Dalbello’s comments only add to the many turf wars going on in the DC swamp over space regulation. Some in Congress want all space regulation to shift to his office. Others want it to be distributed across a number of agencies in both the military and civilian bureaucracies.

Regardless, Dalbello’s office is the agency that might actually have the legal authority for regulating space junk. And it is certain that the FCC does not have it.

NASA now aiming for SLS launch in November

1:52 am

In finding that Hurricane Ian caused little damage at its vehicle assembly building at Kennedy, NASA managers have decided to target the the November 12 to 27 launch window for the first launch of its SLS rocket.

According to this graph [pdf], November 27th is the only date that will provide NASA with the longest mission for Orion (38 to 42 days). Furthermore, the mission precludes launches on November 13, 20-21, and 26.

Expect them to aim for November 12th, even though that will result in an Orion mission only 26 to 28 days long.

Firefly successfully completes first orbital launch of its Alpha rocket

12:19 am

Alpha 1:48 into flight

Capitalism in space: Firefly, a company that just two years ago had gone into bankruptcy, tonight successfully launched their new Alpha rocket into orbit on its second test launch. The screen capture to the right shows the rocket 1:48 minutes into flight, its first stage still firing.

A final 2nd stage engine burn has completed, and we now have confirmation of deployment of the payload satellites. My sources tell me that the second stage under-performed, putting the satellites into a 223x283km orbit, rather than the planned 300km orbit, which will shorten the lifespan of the smallsats. As this was a test launch, not an operational one, this issue does not to my mind make the launch a failure.They reached orbit and the satellites were successfully deployed.

Thus, Firefly now joins SpaceX, Rocket Lab, ULA, Virgin Orbit, and Northrop Grumman as an operational American commercial rocket companies. Astra had been operational, but it has stepped down as it builds a new rocket.

The leaders in the 2022 launch race:

43 SpaceX
41 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise now leads China 61 to 41 in the national rankings, and is tied with the entire world combined, 61 to 61.

Watching Firefly’s next attempt to launch tonight

8:55 pm

Firefly will try again to complete the first successful launch of its Alpha rocket tonight from Vandenberg Space Force Base.

Last night they attempted twice to launch, the first aborting about 4 minutes before launch, the second aborting at T-0, with the first stage engine’s actually igniting and then shutting down.

I have embedded the live stream below. The launch window opens at 12:01 am (Pacific) and lasts two hours, giving them time for at least two launch attempts, should an abort occur on the first attempt.

A look back at Virgin Galactic’s failed history

10:25 am

Link here. Doug Messier has probably provided the best news coverage of every up and down (mostly down) of Virgin Galactic since its beginning. As he notes at the beginning of his article:

A lot can happen in 18 years.

A mother can go from holding her newborn baby in her arms to sending her child off the college for the first time. In between, the child has learned to walk and talk, endured the rigors of puberty, and spent at least 13 years in school.

During that same time, Virgin Galactic essentially accomplished nothing, while wasting billions in private investment capital. Meanwhile, Richard Branson pumped and dumped, getting out when the getting was good and leaving others to hold the bag.

Definitely worth the read. The story of Virgin Galactic demonstrates the risks inherent in capitalism and freedom. Freedom allows for big dreams, but before you commit to any dream you better look it over very carefully or you might be burned.

FCC approves new regulation requiring defunct satellite deorbit in five years

10:13 am

Despite questions from Congress and others about the agency’s legal authority to do so, the FCC yesterday approved a new regulation that will require satellite companies to de-orbit defunct satellites within five years, shortening the rule from the previous requirement of 25 years.

Commissioners voted 4-0 to adopt the draft rule, published earlier this month, intended to address growing debris in LEO. Under the new rule, spacecraft that end their lives in orbits at altitudes of 2,000 kilometers or below will have to deorbit as soon as practicable and no more than five years after the end of their mission. The rule would apply to satellites launched two years after the order is adopted, and include both U.S.-licensed satellites as well as those licensed by other jurisdictions but seeking U.S. market access.

The article notes how this rule replaces “a longstanding FCC guideline” Note the difference. Previously the FCC had made a recommendation, recognizing it did not have the authority to impose it. Now, our power-hungry DC bureaucracy has decided it can ignore the law and impose any rule it desires. Nor does it feel it needs to listen to Congress, one committee of which sent a stern letter recently questioning the then proposed new rule and calling for the FCC to hold off any action on it while elected officials review the situation.

The FCC yesterday responded, essentially telling Congress to bug off.

None of these questions have anything to do with whether this rule makes sense. It likely does, but that still doesn’t give FCC officials to right to arbitrarily give themselves more power. Whether our elected officials will act to defend their own power is uncertain, as the pattern in the past half century is for Congress to consistently cede its power to the bureaucracy, whenever challenged.

NASA releases first Juno image from the first close fly-by of Europa in decades

NASA yesterday released the first image from the successful close fly-by by Juno of Jupiter’s moon Europa since the 1990s. That photo, reduced and sharpened, is above.

The first picture NASA’s Juno spacecraft took as it flew by Jupiter’s ice-encrusted moon Europa has arrived on Earth. Revealing surface features in a region near the moon’s equator called Annwn Regio, the image was captured during the solar-powered spacecraft’s closest approach, on Thursday, Sept. 29, at 2:36 a.m. PDT (5:36 a.m. EDT), at a distance of about 219 miles (352 kilometers).

This is only the third close pass in history below 310 miles (500 kilometers) altitude and the closest look any spacecraft has provided at Europa since Jan. 3, 2000, when NASA’s Galileo came within 218 miles (351 kilometers) of the surface.

Meanwhile, the raw images have been pouring in, and citizen scientists have been quickly processing them. The photo to the right is only one example, created by Kevin Gill. I have cropped it to show one section in full resolution.

Expect many more processed images, especially those taken at closest approach, in the coming days.
