Nope they're using solids

>Mars Ascent Vehicle (MAV) is a two-stage, solid-fueled rocket that will deliver the collected samples from the surface of Mars to the Earth Return Orbiter. Early in 2022, Lockheed Martin was awarded a contract to partner with NASA's Marshall Space Flight Center in developing the MAV and engines from Northrop Grumman. It is planned to be catapulted upward as high as 4.5 m (15 ft) above the lander – or 6.5 m (21 ft) above the Martian surface, into the air just before it ignites, at a rate of 5 m (16 ft) per second, to remove the odds of wrong liftoff like slipping or tilting of SRL under rocket's shear weight and exhaust at liftoff. The front would be tossed a bit harder than the back, causing the rocket to point upward, toward the Martian sky. Thus, the Vertically Ejected Controlled Tip-off Release (VECTOR) system adds a slight rotation during launch, pitching the rocket up and away from the surface.

It's even more looney toons than you'd think

https://arstechnica.com/space/2023/09/independent-review-finds-mars-sample-return-mission-important-but-broken/

> "MSR is a deep-space exploration priority for NASA," the report states. "However, MSR was established with unrealistic budget and schedule expectations from the beginning. MSR was also organized under an unwieldy structure. As a result, there is currently no credible, congruent technical, nor properly margined schedule, cost, and technical baseline that can be accomplished with the likely available funding."

> The findings of the independent review, led by Orlando Figueroa, a retired deputy center director for science and technology at NASA’s Goddard Space Flight Center, echo a report published by Ars Technica about three months ago raising serious questions about costs and schedule. The concern expressed by some scientists, including former NASA science chief Thomas Zurbuchen, was that the ballooning cost of Mars Sample Return would cannibalize funding from other science missions.

> The report says that NASA must do a better job of engaging with the planetary science community to explain its prioritization of the mission and its status as the culmination of a decades-long Mars exploration strategy. Moreover, the reviewers said canceling Mars Sample Return would *not* free up billions of dollars for other planetary science missions.

> "A particular and understandable concern from the community is the impact that MSR may have on the rest of the Planetary Science Division," the report states. "NASA must address this concern while clarifying and dispelling the notion that cancelling MSR necessarily means greater budgets for everybody else in the Planetary Science Division or even the Mars Exploration Program. Cancellation may also call into question the feasibility of other ambitious sample return efforts envisioned by the planetary science community."

Science's byproducts, which is knowledge, is ultimately for our (human) understanding of the universe. In other words, your argument is whether or not we should have humans on the surface studying geology, chemistry, etc. The problem is, and any senior Aerospace Engineering undergrad can tell you this fact: Mission planning, design, and - most importantly - costs all skyrocket when there is a human in the loop. You can get the same research done on Earth, using human eyes, hands, and brains, utilizing cheaper, safer, and easily made return probes.

We should be on Mars someday, but the human economy is a piece of our civilization. There's no escaping that.

actually they're just shit
compressed hydrogen is an absolute mega asspain to deal with: diffusion and leaks everywhere, destroys infra and end user equipment with embrittlement, mandatory gigantic turbo-expensive COPVs, terrible range due to volumetric energy density approaching zero, and the fuel cells themselves are fragile little butterflies that decompose at almost the same rate as lithium battery cells and also require rare and expensive materials. Also, more than 95% of hydrogen is produced as a by-product of refining fossil fuels, so it's incredibly dirty even compared to electricity from a modern coal-fired powerplant.

all of this combines to mean that hydrogen electric fuel cell cars are: more expensive, slower, less powerful, shorter range, more difficult to fuel, require much more maintenance, and are also more polluting than electric vehicles. none of these are unforseen problems or the result of a conspiracy, hydrogen is just that shit.

Single celled ones if we're being realistic here. What's even energetically available on Europa? On Earth, oceanic chemoautotrophs never developed beyond simple prokaryotic forms despite a billion years of having the place to themselves.

>>15763207
in the short run it wouldn't do anything as the FAA and other parties have to create the laws to regulate commercial human spaceflight, this just extends the moratorium on it for eight more years

>>15763222
>the FAA and other parties have to create the laws
They'd have to create the regulatory framework within the purview of their legal mandate. The law can only be made by the Legislative branch, and the FAA is part of the Executive.

Speaking of FAA shenanigans it looks like they took the FCC's mandatory-deorbit suggestion and tried to make a rule with it: https://spacenews.com/faa-proposes-rule-to-limit-lifetime-of-upper-stages-in-orbit/

Payload to orbit down, but in exchange less space debris

>>15764183
payload to orbit not down necessarily, but cost will go up
one of the mitigation choices is to use pay some other company to deorbit the stage for you, so you could have spacetugs or whatever that specifically go and push trash down into the atmosphere, but obviously that increases effective cost

What the tank doin'?

Explanation: What are those dark streaks in this composite image of a solar eclipse? They are reversed shadows of mountains at the edge of the Moon. The center image, captured from Xiamen, China, has the Moon's center directly in front of the Sun's center. The Moon, though, was too far from the Earth to completely block the entire Sun. Light that streamed around the edges of the Moon is called a ring of fire. Images at each end of the sequence show sunlight that streamed through lunar valleys. As the Moon moved further in front of the Sun, left to right, only the higher peaks on the Moon's perimeter could block sunlight. Therefore, the dark streaks are projected, distorted, reversed, and magnified shadows of mountains at the Moon's edge. Bright areas are called Baily's Beads.

>>15764242
>edge
Reeee
It's limb when you're talking about celestial bodies

>>15763486
I don't think I implied it was a single piece. Maybe you thought I was implying by not helping you visualize it. There would be a stationary cylinder with a spinning cylinder inside. The composition of the rock would not matter that much.

UAW is a dying breed. Tesla is about to have more headcount employees than UAW combined from all it's plants. Tesla employee stock value went up nearly 2000%. For those vested, they're millionaires.

Further, the more Tesla succeeds in killing UAW work, the more Tesla employees get to reap reward on the future. Every single Tesla employees will be multimillionaire if Tesla succeeds in hemorrhaging GM/Ford/Stellantis/VW.

>Prospects for use of O4 as rocket fuel oxidizer

>an overview of rocket fuel existing oxidants, their technical properties and their specific impulse with kerosene. Compounds of super peroxides (superoxides) as oxidizing agents with higher specific characteristics are proposed. It is calculated that the specific impulse of O4 compound with kerosene can be about 4500 m/s, i.e. 30% more than with liquid oxygen, and the launch mass of the rocket can be halved. It is concluded that O4 is promising as an oxidizer of rocket fuel. It is described: the principal possibilities of O4 electrochemical production, methods for stabilizing of O4 chemical compounds at normal temperature, the stages of O4 possible industrial production. It is given the possible cost of O4 in the production of 300 tons per year.

wouldn't stored gaseous O2/H2 be entirely self pressurized by default? what does stirring the tanks even mean in this context

>>15765235
no, that's a different country

>>15765057
it physically cannot explore the poles because of the lack of line of sight commumication with Earth, as a direct result of not including a titan orbiter to bounce the signal to Earth. Basically the mission can't visit the poles by design.

>>15765124
it's a nice dark blue color and has a big moon for its size.

>>15765252
just to clarify Titan is so far away that from Titan's perspective Earth is so close to the Sun that when it's night that basically means there's no line of sight to Earth and no signal. Anyway shouldn't one pole be in sunlight when the other is not?

>>15765258
yes I'm aware of the nighttime communications blackout. Keep in mind NASA is the entity saying the probe cannot and will not go to the poles. Also having the Earth like 1 degree above the horizon it's good enough to allow communications apparently, Earth needs to appear high in the sky from wherever the probe is on Titan in order for it to connect.

>>15765124
It's a very reasonable size
