With giant storms, powerful winds, auroras, and extreme temperature and pressure conditions, Jupiter has a lot going on. Now, NASA’s James Webb Space Telescope has captured new images of the planet. Webb’s Jupiter observations will give scientists even more clues to Jupiter’s inner life.  

“We hadn’t really expected it to be this good, to be honest,” said planetary astronomer Imke de Pater, professor emerita of the University of California, Berkeley. De Pater led the observations of Jupiter with Thierry Fouchet, a professor at the Paris Observatory, as part of an international collaboration for Webb’s Early Release Science program. Webb itself is an international mission led by NASA with its partners ESA (European Space Agency) and CSA (Canadian Space Agency). “It’s really remarkable that we can see details on Jupiter together with its rings, tiny satellites, and even galaxies in one image,” she said. 

The two images come from the observatory’s Near-Infrared Camera (NIRCam), which has three specialized infrared filters that showcase details of the planet. Since infrared light is invisible to the human eye, the light has been mapped onto the visible spectrum. Generally, the longest wavelengths appear redder and the shortest wavelengths are shown as more blue. Scientists collaborated with citizen scientist Judy Schmidt to translate the Webb data into images. 

In the standalone view of Jupiter, created from a composite of several images from Webb, auroras extend to high altitudes above both the northern and southern poles of Jupiter. The auroras shine in a filter that is mapped to redder colors, which also highlights light reflected from lower clouds and upper hazes. A different filter, mapped to yellows and greens, shows hazes swirling around the northern and southern poles. A third filter, mapped to blues, showcases light that is reflected from a deeper main cloud.  

The Great Red Spot, a famous storm so big it could swallow Earth, appears white in these views, as do other clouds, because they are reflecting a lot of sunlight. 

“The brightness here indicates high altitude – so the Great Red Spot has high-altitude hazes, as does the equatorial region,” said Heidi Hammel, Webb interdisciplinary scientist for solar system observations and vice president for science at AURA. “The numerous bright white ‘spots’ and ‘streaks’ are likely very high-altitude cloud tops of condensed convective storms.” By contrast, dark ribbons north of the equatorial region have little cloud cover.

Russia launches satellite stalking satellite.

INTERESTING ENGINEERING: In covert space operations news, a strange Russian satellite that is apparently intended to eavesdrop on U.S. military satellites in orbit has just been launched. At its current trajectory, it should be able to close in on its target sometime on August 4th, 2022.

Before its launch, the new Russian spacecraft was rumored to be an "inspector" satellite and is thought to be specifically designed to stalk other satellites to get a closer look. The espionage satellite, which is expected to be given the name Kosmos 2558, was put into the same orbit as the USA 326 military satellite, which was launched in February.

The Russian satellite was launched at a time when the American satellite was traveling above the Russian spaceport of Plesetsk, according to Marco Langbroek, an astrodynamics lecturer at Delft Technical University in the Netherlands, who followed the two satellites' orbital planes.

“The two orbits are very close, the main difference being a relatively small difference of a few tens of kilometers in orbital altitude,” Langbroek told Gizmodo in an interview. “So that is a very clear indication.”

The U.S. satellite is moving in a 97.4-degree inclined Sun-synchronous orbit, while the Russian satellite is moving in a 97.25-degree inclined orbit, explained Langbroek. The Russian satellite might also maneuver its orbit within the next few days to move even closer to its U.S. counterpart.

“If one or both of them do not maneuver in the meantime, Kosmos 2558 will pass USA 326 at a distance of approximately 75 kilometers (46 miles) on August 4th, near 14:47 UTC [10:47 a.m. ET],” Langbroek said.
Satellite stalking is not exactly something new

According to experts like Langbroek, this type of Russian satellite has already been used to stalk satellites in orbit.

“Presumably, it has some kind of sensor system that’s optimized to observe other satellites, rather than the sort of usual observing satellite that’s optimized to take pictures of the ground,” Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, also told Gizmodo. “We don’t know that for sure, we’re just inferring that from how it’s behaving.”

Video shows multiple explosions at Russian Air Base in Russian-occupied Crimea

Huge explosions at the Saki Air Base (Novofedorivka) in Russian-occupied Crimea after possible Ukrainian strikes this afternoon. 

Oleg Kryuchkov, adviser to the head of the Crimean region -- which Russia annexed from Ukraine in 2014 -- confirmed several explosions had occurred near the village of Novofedorivka.

On his Telegram channel, Kryuchkov said: "So far, I can only confirm the fact of several explosions in the Novofedorivka area. I ask everyone to wait for official messages."
Separately, Sergey Aksenov, the head of the so-called Republic of Crimea, said "I went to the scene in the village of Novofedorivka, Saki district. The circumstances are being clarified."

There was no word from the Ukrainian side about any possible attacks in the area. Ukraine is not known to have struck the territory of Crimea since the Russian invasion began.

Russian Television quickly sent out an explanation saying it was an accident: 

"Huge explosions reported near a Russian military base in Crimea were the result of an accident at an ammunition storage facility, according to Russia’s MoD. No one was injured in the accident and damage to the stored equipment has apparently been minimal, officials added. Emergency services are combating the flames on site. An investigation into the exact causes of the accident is underway."

Saki is a homebase of the 43rd Separate Naval Assault Aviation Regiment of the Black Sea Fleet (warplanes: Su-30SM, Su-24M, Su-24MP, Tu-134).

Zawahiri killed in drone Hellfire 9x "Flying Ginsu" strike .

US officials on Monday said that US forces in a drone strike in Kabul, Afghanistan. In a televised address, President Joe Biden announced his death and said no civilian casualties were reported in the operation that was conducted over the weekend.

Quoting a senior official in the Biden administration, news agency AFP said that Zawahiri was on the balcony of a house in Kabul when he was targeted with two Hellfire missiles, an hour after sunrise on July 31.

According to the official's account, Biden gave his green light for the strike on July 25 - as he was recovering in isolation from Covid-19.

However, pictures from the Kabul home where Zawahiri was living showed no signs of an explosion, pointing to the use again by the US of the macabre Hellfire R9X.

But, What is Hellfire 9X?

Hellfire 9X is also called the "ninja bomb". It is reportedly said that the missile has become the US weapon of choice for killing leaders of extremist groups while avoiding civilian casualties.

The missile is fired from a Predator drone. It has no warhead, but deploys six blades which fly in at high speed, crush and slice the targeted person.

This is the reason why it is called the "flying ginsu", after the 1980 TV commercial for Japanese kitchen knives that would cut cleanly through aluminum cans and remain perfectly sharp.

Some pictures posted online show the impact of these missiles. One of these old photos on Twitter claims to show a car destroyed by Hellfire R9X in Idlib, Syria.


Why are these missiles used in special cases?

In a report, the Wall Street Journal said that the missiles were born after former US President Barack Obama emphasized on avoiding civilian deaths in US airstrikes in Afghanistan, Pakistan, Iraq, Syria, Somalia, Yemen and other countries.

The R9X variant of Hellfire is used only in specific circumstances, particularly when a terrorist leader has been pinpointed. It is intended to limit damage compared to typical missiles by reducing the risk of killing innocent civilians around the target.

Aircraft spots: UAE C-17 spotted in Amarillo picking up two AH-1Z viper helicopters

Super rare visit in Amarillo from a United Arab Emirates C-17 as they flew in to pickup two 2 AH-1Z Vipers for Bahrain. Needless to say I was there to document it.

Funny thing, millions of dollars of aviation hardware on the ramp and what it finally comes down to loading it - is old fashioned human muscle pushing it like my old Buick that wouldn't start.

Bahrain is to receive its AH-1Z attack helicopters under an FMS deal that was first approved in April 2018 and signed in February 2019. The helicopters are being built under the US military’s Lot 16 production run, with deliveries to Bahrain now expected to commence later this year.

As noted by the US Defense Security and Cooperation Agency (DSCA) when the procurement was first approved, in addition to the 12 AH-1Z helicopters, Bahrain is to also acquire Lockheed Martin AGM-114 Hellfire air-to-surface missiles and BAE Systems Advance Precision Kill Weapon System (APKWS) II guided rockets, as well as Thales’ TopOwl helmet-mounted display system.

The total value of the deal, including spares, support, and ancillary equipment, was estimated by the DSCA to be USD911.4 million.
