pa dobro, nisu loši ovi filmovi kad prikazuju ulazak brodova u atmosferu!

A rare cosmic eruption is expected to occur in the Milky Way in the coming months — an outburst so bright that a “new” star will seemingly appear for a short time in the night sky.

The event, known as a nova, will be a once-in-a-lifetime skywatching opportunity for those in the Northern Hemisphere, according to NASA, because the types of star systems in which such explosions occur are not common in our galaxy.

At its peak, the eruption should be visible to the naked eye, Schaefer said: “It’s going to be bright in the sky, so it’ll be easily visible from your backyard.”

“It could maybe even happen tonight,” Schaefer said. “More probably it’ll be within the next couple of months, and very probably before the end of summer.”

Koji su ovi carevi: poslali letelicu na jedan asteroid, vratili uzorke na Zemlju, pa poslali letelicu ka sledećem asteroidu. Sve u jednom letu.

haha, stvarno kul. odlične su im i fotke.

Kakve su sve lude ideje imali 🙂 Raketa na tečni litijum 🙂

hahaha, istina 🙂

makar nisu kuće od njih pravili u kojima su ljudi živeli do pre deset godina 🙂

Prva orbitalna stanica oko Meseca. Prvi moduli bi trebalo da se postave u orbitu najranije sledeće godine.

Kinezima pobegla raketa tokom testa statičnog paljenja. Ne zna se još da li i koliko ljudi je stradalo.

videh ovo sinoć, jedino strašnije od eksplozije je ovaj lik što je snimao.

Četvrti let Starship-a. Za peti je u planu da ga hvataju onim džinovskim "kineskim štapićima"

Што је још занимљивије канал Гедиз Валис, где је Кјуриозити пронашао камен, препун је сличних стена попут оне коју је ровер смрвио што значи да су неки делови планете богати чистим сумпором.

„Проналажење камења од чистог сумпора је као да пронађете оазу у пустињи. Не би требало да је тамо, тако да морамо то да објаснимо. Откривање неочекиваних ствари је оно што чини планетарно истраживање занимљивим“, наводи научник Ешвин Васавада из Насине "Jet Propulsion Laboratory".

Сулфати су соли које се формирају када се сумпор меша са другим минералима уз присуство воде. Када вода испари, минерали се сједињују и остају сулфати.

Jbt ovi mučenicu su još gore. Evo sada i SpaceX ima nekih problema.

Already more than a month late getting back, two NASA astronauts will remain at the International Space Station until engineers finish working on problems plaguing their Boeing capsule, officials said Thursday.

...

After the space shuttles retired, NASA hired private companies for astronaut rides to the space station, paying Boeing and SpaceX billions of dollars.

This was the Boeing's first test flight with a crew aboard. The initial demo in 2019, flying empty, never made it to the space station because of bad software, and Boeing repeated the test in 2022. More issues later cropped up.

SpaceX has been ferrying astronauts since 2020. SpaceX's Falcon 9 rockets have been grounded for the past two weeks because of an upper-stage failure on a satellite-delivery mission. The longer the stand-down continues, the more likely upcoming crew flights will be delayed.

Neka zovu Putina više.

Canadarm2 robotska ruka se sprema da uhvati letelicu po 50. put.

Zanimljivo je što ona nije uopšte dizajnirana za taj posao; a posebno je interesantno što je kroz nju kanadska svemirska agencija ušla na ISS projekat i praktično finansirala svoj svemirski program.

Možda ih Elon vrati u februaru 2025.

Scientists from the University of California, Berkeley, and UC San Diego, have discovered evidence of large amounts of liquid water lurking deep beneath the surface of Mars, according to peer reviewed research published in the Proceedings of the National Academy of Sciences.

Using seismic data from Mars quakes, volcanic rumblings and meteor impacts gathered by NASA’s InSight lander and the same kind of mathematical models of rock physics used to map underground aquifers and oil fields on Earth, the researchers uncovered evidence of a deep water reservoir located in deep beneath the martian surface in tiny cracks and pores in the planet’s crust.

The water, which data suggests is located between 11.5 and 20 kilometers below the martian surface—around 7 to 12 miles—is probably inaccessible with existing technology, the researchers said, so is likely to be of little use to a future Mars colony.

Despite this, the researchers said the discovery reveals important details about Mars’ history and, if the water can be tapped, is a promising place to look for alien life on the Red Planet.

“I don't see why [the underground water] is not a habitable environment,” said one of the study’s authors and a professor of earth and planetary science at Berkeley, Michael Manga, noting that far down environments on Earth like “deep, deep mines” and the “bottom of the ocean” host life as well.

“We haven't found any evidence for life on Mars, but at least we have identified a place that should, in principle, be able to sustain life,” Manga said.

Manga heh...znaci Mars je jos geoloski aktivan kad ima dovoljno toplo jezgro da na 20km dubine voda bude u tecnom stanju.
