O meglio, l'atterraggio del rover Curiosity, lanciato nel 2011, è programmato per quella data.
Magari non interessa, ma il video - si ringrazia Paolo Attivissimo - mi ha incuriosito parecchio e mi ha fatto venire voglia di seguirne l'atterraggio tra circa un mesetto
Enjoy

Il profilo dell'arrivo su Marte è veramente folle, spero che vada bene.
Non è mai stato tentato prima nulla del genere, e anche solo la consapevolezza che non si tratta di qualche film di fantascienza ma di un evento reale fa un po' venire la pelle d'oca, ma sarà necessario padroneggiare questa tecnica del "powered descent" (invece di cozzare avvolti in airbag) per trasportare carichi più massicci.
Il bello è che, a causa della distanza di Marte dalla Terra, i controllori inizieranno a ricevere dati sull'entrata nell'atmosfera quando sarà già tutto finito.
Per chi volesse seguire la diretta dei "7 Minutes of Terror" qui un LINK alle 7:30 MMT (My Mean Time) . Mi piacciono queste nuove tecniche di atterraggio , speriamo vada come da programma.
NASA/JPL ground controllers react to learning the the Curiosity rover had landed safely on Mars and begun to send back images to NASA's Jet Propulsion Laboratory on Sunday, Aug. 5, 2012.
The rover will assess whether Mars ever had an environment able to support life forms.
...saranno le solite frasi banali ma.....ragazzi, solo un centinaio d'anni fa spiccavamo i primi voli......
Io ero rimasto alle mega palle che rimbalzavano su Marte... questi sono entrati nell'atmosfera, hanno aperto il paracadute, hanno sganciato un modulo tipo lem che si è stabilizzato e a sua volta ha calato con delle "corde" il rover.....ma come c....o hanno fatto??

Cronologia degli eventi durante i "7 min di terrore"
Some events in the control room as they arrived (14 minutes after they actually took place on Mars):
10:14 lost telemetry, received heartbeat signals
10:15 cruise stage separation, vehicle turns to the correct attitude, which means that the reaction control system rockets are working
10:20 5 minutes to entry, heartbeat tones still coming, spacecraft at about 5.5 km/sec
10:22 MRO began storing data for retransmission
10:24 reentry began, signal dropped, indicating a change in antennas
10:26 Odyssey data begins flooding in, MSL deccelerating at about 11 G's
10:28 17 kilometers altitude
10:29 down to about Mach 2, parachute will deploy at Mach 1.7
10:30 parachute deployed!!! Spacecraft decelerating well!
10:30 still descending, at 6.9 kilometers
10:31 86 meters/second, 4.2 kilometers and descending
10:31 powered flight!!! yes!!! down to 500 meters altitude, 50 m/sec
10:32 10m/sec, 40 m altitude
10:32 1.5m/sec descending, skycrane is working!!!
10:32 touchdown confirmed!!!! The skycrane worked!!!! Joy in control room. Everyone's faces are red.
10:34 first thumbnail of Curiosity's wheel rolls in, cameras working
10:35 full-sized picture with Curiosity's wheel, Martian horizon arrives to sheer joy in the control room
Touchdown time was 10:14:39 PM Pacific Time, 0.04435, 140.46 kg of fuel remaining (out of 400 kg to start) in descent stage as it flew away
Tenete conto che i Russi (e prima di loro i Sovietici), per quanto riguarda le missioni in direzione di Marte, hanno un bilancio che non può essere definito positivo .....
..... finito in mezzo a roventi e ..... paradossali polemiche .....
According to Reuters, Medvedev said at the weekend: "Recent failures are a strong blow to our competitiveness... we need to carry out a detailed review and punish those guilty.
"I am not suggesting putting them up against the wall like under Josef [Stalin], but seriously punish either financially or, if the fault is obvious, it could be a disciplinary or even criminal punishment."
Questa sera doveva uscire la nuova edizione ma, almeno per ora, non è ancora apparsa ..... probabilmente stanno preparando il resoconto dell' avvenimento .....
Il settimanale online "The Space Review" ha appena pubblicato, come prevedibile, un articolo dedicato all'arrivo su Marte del "Mars Science Laboratory (MSL)" .....
Ha dell'incredibile la straordinaria immagine dello MLS, mentre scende sul pianeta appeso al suo paracadute, scattata dalla sonda orbitale "Mars Reconnaissance Orbiter" che stava sorvolando la zona .....
This color thumbnail image was obtained by NASA's Curiosity rover during its descent to the surface of Mars on Aug. 5 PDT (Aug. 6 EDT).
The image was obtained by the Mars Descent Imager instrument known as MARDI and shows the 15-foot (4.5-meter) diameter heat shield when it was about 50 feet (16 meters) from the spacecraft.
It was obtained two and one-half minutes before touching down on the surface of Mars and about three seconds after heat shield separation.
It is among the first color images Curiosity sent back from Mars.
The resolution of all of the MARDI frames is reduced by a factor of eight in order for them to be promptly received on Earth during this early phase of the mission.
Full resolution (1,600 by 1,200 pixel) images will be returned to Earth over the next several months as Curiosity begins its scientific exploration of Mars.
The original image from MARDI has been geometrically corrected to look flat.
Curiosity landed inside of a crater known as Gale Crater.
Behold Mount Sharp! .....
This image taken by NASA's Curiosity shows what lies ahead for the rover, its main science target, Mount Sharp.
The rover's shadow can be seen in the foreground, and the dark bands beyond are dunes.
Rising up in the distance is the highest peak Mount Sharp at a height of about 3.4 miles, taller than Mt. Whitney in California.
The Curiosity team hopes to drive the rover to the mountain to investigate its lower layers, which scientists think hold clues to past environmental change.
This image was captured by the rover's front left Hazard-Avoidance camera at full resolution shortly after it landed.
It has been linearized to remove the distorted appearance that results from its fisheye lens.
Curiosity's First Color Image of the Martian Landscape .....
This view of the landscape to the north of NASA's Mars rover Curiosity was acquired by the Mars Hand Lens Imager (MAHLI) on the afternoon of the first day after landing.
(The team calls this day Sol 1, which is the first Martian day of operations; Sol 1 began on Aug. 6, 2012.)
In the distance, the image shows the north wall and rim of Gale Crater.
The image is murky because the MAHLI's removable dust cover is apparently coated with dust blown onto the camera during the rover's terminal descent.
Images taken without the dust cover in place are expected during checkout of the robotic arm in coming weeks.
The MAHLI is located on the turret at the end of Curiosity's robotic arm.
At the time the MAHLI Sol 1 image was acquired, the robotic arm was in its stowed position.
It has been stowed since the rover was packaged for its Nov. 26, 2011, launch.
The MAHLI has a transparent dust cover.
This image was acquired with the dust cover closed.
The cover will not be opened until more than a week after the landing.
When the robotic arm, turret, and MAHLI are stowed, the MAHLI is in a position that is rotated 30 degrees relative to the rover deck.
The MAHLI image shown here has been rotated to correct for that tilt, so that the sky is "up" and the ground is "down".
When the robotic arm, turret, and MAHLI are stowed, the MAHLI is looking out from the front left side of the rover.
This is much like the view from the driver's side of cars sold in the USA.
The main purpose of Curiosity's MAHLI camera is to acquire close-up, high-resolution views of rocks and soil at the rover's Gale Crater field site.
The camera is capable of focusing on any target at distances of about 0.8 inch (2.1 centimeters) to infinity.
This means it can, as shown here, also obtain pictures of the Martian landscape.
