The first of the SpaceX Dragon resupply missions is scheduled for launch today, 7 October, at 5:35 PM Phoenix time (8:35 PM EDT and 00:35 UTC).

You can view the SpaceX webcast here (coverage starts at 4:55 PM Ohoenix time), watch it on NASA TV.

The SpaceX / NASA prelaunch press conference is at 3:00 PM Phoenix time on NASA TV.

The schedule for the first 10 minutes:

  • 00:00 Falcon 9 launch
  • 00:25 Max Q (moment of peak mechanical stress on the rocket)
  • 03:00 1st stage engine shutdown/main engine cutoff (MECO)
  • 03:05 1st and 2nd stages separate
  • 03:12 2nd stage engine starts
  • 03:52 Dragon nose cone jettisoned
  • 09:11 2nd stage engine cutoff (SECO)
  • 09:46 Dragon separates from 2nd stage

Weather outlook is for 40% chance of unfavorable weather, mostly a thick cloud violation, with some chance of flight through precipitation.

Cargo for the ISS on this mission includes:

  • 260 pounds of crew food, clothing, low-sodium food kits and other crew supplies.
  • 390 pounds of science gear, including a low-temperature Glacier freezer for experiment samples, fluids and combustion facility hardware, a commercial generic bioprocessing apparatus, cables for the Alpha Magnetic Spectrometer and research gear for the Japanese and European space agencies.
  • 225 pounds of space station hardware, including crew health care system components, life support system parts, filters and electrical components.
  • 7 pounds of computer gear.

Return to Earth:

  • 163 pounds of crew supplies.
  • 518 pounds of vehicle hardware.
  • 123 pounds of computer gear, Russian cargo and spacewalk equipment.
  • 866 pounds of science gear and experiment samples, including 400 samples of crew urine.

Curiosity – Arm Camera on Sol 30

This image of MAHLI was taken from the left eye of the Mast Camera (MastCam) during the 30th Sol on Mars. The pink circle in the center of the image is the dust cover on the MAHLI camera, which is about 10 cm in diameter. The triangular mechanism to the right of the camera is the wire brush dust removal tool.

Curiosity has now traveled more than the length of a football field (American Football). The tracks left on the surface have been imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (image below).

The next week will be filled with testing the robotic arm. Daniel Limondi said:

We will be putting the arm through a range of motions and placing it at important ‘teach points’ that were established during Earth testing, such as the positions for putting sample material into the inlet ports for analytical instruments. These activities are important to get a better understanding for how the arm functions after the long cruise to Mars and in the different temperature and gravity of Mars, compared to earlier testing on Earth.

Once these tests are completed and results analyzed, Curiosity will continue on toward Glenelg, where it is expected to scoop soil, drill into rocks, process collected samples and deliver a sample into the analytical instruments.

Curiosity – From Here To There

Curiosity Descent Captured by Mars Reconnaisance Orbiter

The Mars Reconnaissance Orbiter captured this image of Curiosity descending beneath its parachute. Alfred McEwen writes about the image taken by the HiRISE camera:

NASA’s Curiosity rover and its parachute were spotted by NASA’s Mars Reconnaissance Orbiter as Curiosity descended to the surface on Aug. 5 PDT (Aug. 6 EDT). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image of Curiosity while the orbiter was listening to transmissions from Curiosity.

Curiosity and its parachute are in the center of the white box; and a separate image is a smaller cutout of MSL stretched to avoid saturation. The rover is landing on the etched plains just north of the sand dunes that fringe “Mt. Sharp.”

The parachute appears fully inflated and performing perfectly. Details in the parachute such as the band gap at the edges and the central hole are clearly visible. The cords connecting the parachute to the backshell cannot be seen, although they were seen in the image of Phoenix descending, perhaps due to the difference in lighting angles.

(The MSL suspension lines are made of material called Technora which has a tan color, while the Phoenix suspension lines were Kevlar which is yellow and this may help explain why they aren’t visible in the image.)

The bright spot on the backshell containing MSL might be a specular reflection off of a shiny area. MSL was released from the backshell sometime after this image was acquired.

This view is one product from an observation made by HiRISE targeted to the expected location of MSL about 1 minute prior to landing. It was captured in HiRISE CCD RED1, near the eastern edge of the swath width (there is a RED0 at the very edge). This means that MSL was a bit further east or downrange than predicted.

The High Resolution Imaging Science Experiment (HiRISE) camera aboard the orbiting Mars Reconnaissance Orbiter captured this dust devil image (above) on 16 February, 2012.

The dust devil is more than one half mile high and about thirty yards in diameter, and was located in the Amazonis Planitia region of northern Mars.

Crater Drains Into A Cavern on Mars

Earlier this year, NASA’s Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) captured an image of a crater with a block dot in the center on the slopes of the Pavonis Mons volcano. Mission managers decided to have another look, this time with the High Resolution Imaging Science Experiment (HiRISE).

The black dot turned out to be a skylight 35 meters across leading into a cavern below. The cavern is likely a lava tube located beneath the surface of the volcano. Based on the shadow, the floor is about 20 meters below the skylight.

Speculation centers on the formation of the crater. It could be a sink hole formed from the loose dust on the volcano flowing into the cavern when the roof collapsed. In this closeup, one can see how the walls of the crater have slumped and material has flowed into the cavern below.

The hole might also be from a small meteorite that punched a hole through the lava tube. There does not seem to be much (if any) rim from a meteorite strike and the crater it would have created. Then, there is speculation that the underground cavern is a former ice deposit that has been exposed and sublimated into the Martian atmosphere.

Later this year, the HiRISE mission plans another image of the crater, creating a stereo picture that may help resolve the mystery.
