Beh, nel piscio c'è acqua

On June 17, NASA’s MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet. Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN has been exploring the upper atmosphere of Mars.
1,000 Days in Orbit: MAVEN’s Top 10 Discoveries at Mars:
10. Imaging of the distribution of gaseous nitric oxide and ozone in the atmosphere shows complex behavior that was not expected, indicating that there are dynamical processes of exchange of gas between the lower and upper atmosphere that are not understood at present.
9. Some particles from the solar wind are able to penetrate unexpectedly deep into the upper atmosphere, rather than being diverted around the planet by the Martian ionosphere; this penetration is allowed by chemical reactions in the ionosphere that turn the charged particles of the solar wind into neutral atoms that are then able to penetrate deeply.
8. MAVEN made the first direct observations of a layer of metal ions in the Martian ionosphere, resulting from incoming interplanetary dust hitting the atmosphere. This layer is always present, but was enhanced dramatically by the close passage to Mars of Comet Siding Spring in October 2014.
7. MAVEN has identified two new types of aurora, termed “diffuse” and “proton” aurora; unlike how we think of most aurorae on Earth, these aurorae are unrelated to either a global or local magnetic field.
6. These aurorae are caused by an influx of particles from the sun ejected by different types of solar storms. When particles from these storms hit the Martian atmosphere, they also can increase the rate of loss of gas to space, by a factor of ten or more.
5. The interactions between the solar wind and the planet are unexpectedly complex. This results due to the lack of an intrinsic Martian magnetic field and the occurrence of small regions of magnetized crust that can affect the incoming solar wind on local and regional scales. The magnetosphere that results from the interactions varies on short timescales and is remarkably “lumpy” as a result.
4. MAVEN observed the full seasonal variation of hydrogen in the upper atmosphere, confirming that it varies by a factor of 10 throughout the year. The source of the hydrogen ultimately is water in the lower atmosphere, broken apart into hydrogen and oxygen by sunlight. This variation is unexpected and, as yet, not well understood.
3. MAVEN has used measurements of the isotopes in the upper atmosphere (atoms of the same composition but having different mass) to determine how much gas has been lost through time. These measurements suggest that 2/3 or more of the gas has been lost to space.
2. MAVEN has measured the rate at which the sun and the solar wind are stripping gas from the top of the atmosphere to space today, along with the details of the removal processes. Extrapolation of the loss rates into the ancient past -- when the solar ultraviolet light and the solar wind were more intense -- indicates that large amounts of gas have been lost to space through time.
1. The Mars atmosphere has been stripped away by the sun and the solar wind over time, changing the climate from a warmer and wetter environment early in history to the cold, dry climate that we see today.

NASA finally admits it doesn’t have the funding to land humans on Mars
"I can't put a date on humans on Mars," chief of human spaceflight says.
naturalmente, spendere per la scienza non è poi cosi' importante come per gli armamenti ^^
se finira' che compagnie private (space x, boeing, blue origin) lo faranno prima, sara' una cosa piuttosto triste perché significhera' che gli usa sono piu' interessati a fare guerre piuttosto che investire nella ricerca (tanto piu' che si parla di frazioni insignificanti rispetto alla spesa per il settore militare).

Re: From mars with love.
CI sarebbero altre cose su cui investire piuttosto che andare a colonizzare un pianeta. Tipo la situazione attuale di questo pianeta che fa schifo al cazzo.
Detto questo quando qualcosa si muoverà noi avremo 70 anni e ci preoccuperemo di dover morire entro cinque, non di andare su marte.

Ti sei dimenticato di dire che si stava meglio quando si stava peggio è che qui una volta era tutta campagna.

Re: From mars with love.
Francamente sono d'accordo: mandare uomini su Marte ha poco senso visto i costi attuali. Piuttosto mandare sciami di robot che preparino il terreno per una futura discesa di esseri umani: infrastrutture, wifi, pr0n...

Re: From mars with love.
Ah perché secondo te mandare un uomo su Marte si intendeva proprio metterlo su di un vettore e spararlo su Marte? :rotolul: dai cazzo siate un filo più "svegli".
