[meteorite-list] Need large and ugly Sikhote Alin

2017-04-04 Thread Mendy Ouzillou via Meteorite-list
Hello everyone,

I have a client that needs some large and ugly (read that cheap) Sikhote
Alin to cut into slices and large blocks. Minimum size required for blocks
in 5cm x 5cm x 5cm (that is cm and not mm). Since this is for cutting, will
accept offers for shrapnel as well as individuals.

Please let me know what you may have available and provide dimensions,
weight and price. After reviewing, I will ask for pictures.

Thanks for your help,

Mendy Ouzillou

NASA Selects CubeSat, SmallSat Mission Concept Studies
Jet Propulsion Laboratory
March 23, 2017

NASA has selected 10 studies under the Planetary Science Deep Space SmallSat 
Studies (PSDS3) program to develop mission concepts using small satellites 
to investigate Venus, Earth's moon, asteroids, Mars and the outer planets.

For these studies, small satellites are defined as less than 180 kilograms 
in mass (about 400 pounds). CubeSats are built to standard specifications 
of 1 unit (U), which is equal to about 4x4x4 inches (10x10x10 centimeters). 
They often are launched into orbit as auxiliary payloads, significantly 
reducing costs.

"These small but mighty satellites have the potential to enable 
transformational 
science," said Jim Green, director of the Planetary Science Division at 
NASA Headquarters in Washington. "They will provide valuable information 
to assist in planning future Announcements of Opportunity, and to guide 
NASA's development of small spacecraft technologies for deep space science 
investigation."

NASA's Science Mission Directorate is developing a small satellite strategy, 
with the goal of identifying high-priority science objectives in each 
discipline that can be addressed with CubeSats and SmallSats, managed 
for appropriate cost and risk. This multi-disciplinary approach will leverage 
and partner with the growing commercial sector to collaboratively drive 
instrument and sensor innovation.

The PSDS3 awardees were recognized this week at the 48th Lunar and Planetary 
Society Conference in The Woodlands, Texas. The total value of the awards 
is $3.6 million.

The recipients are:

David Minton, Purdue University, West Lafayette, Indiana: Chariot to the 
Moons of Mars, a 12-unit CubeSat with a deployable drag skirt to produce 
high-resolution imagery and surface material composition of Phobos and 
Deimos, to help understand how they were formed.

Anthony Colaprete, NASA Ames Research Center, Moffett Field, California: 
Aeolus, a 24-unit CubeSat to directly measure vertically-resolved global 
winds to help determine the global energy balance at Mars and understand 
daily climate variability.

Icy Bodies and Outer Planets

Kunio Sayanagi, Hampton University, Virginia: Small Next-generation Atmospheric 
Probe (SNAP), an atmospheric entry probe to measure vertical cloud structure, 
stratification, and winds to help understand the chemical and physical 
processes that shape the atmosphere of Uranus.

Robert Ebert, Southwest Research Institute, San Antonio: JUpiter MagnetosPheric 
boundary ExploreR (JUMPER), a SmallSat to explore Jupiter's magnetosphere, 
including characterizing the solar wind upstream of the magnetosphere 
to provide science context for future missions such as the Europa Clipper.

[meteorite-list] Prolific Mars Orbiter Completes 50, 000 Orbits (MRO)

Prolific Mars Orbiter Completes 50,000 Orbits
Jet Propulsion Laboratory
March 29, 2017

The most data-productive spacecraft yet at Mars swept past its 50,000th 
orbit this week, continuing to compile the most sharp-eyed global coverage 
ever accomplished by a camera at the Red Planet.

In addition, the spacecraft -- NASA's Mars Reconnaissance Orbiter (MRO) 
-- recently aided preparations for NASA's next mission to Mars, the InSight 
lander. Insight will launch next year on a mission to study the planet's 
deep interior. Meanwhile, the orbiter continues diverse science observations 
of Mars and communications-relay service for two active Mars rovers, Curiosity 
and Opportunity.

MRO's Context Camera (CTX) exploits a sweet spot in the balance between 
resolution and image file size. With a resolution of about 20 feet (6 
meters) per pixel in images of the Martian surface, it has provided a 
library of images now covering 99.1 percent of Mars. That is approximately 
equivalent to the land area of Earth. No other camera ever sent to Mars 
has photographed so much of the planet in such high resolution.

The Context Camera has taken about 90,000 images since the spacecraft 
began examining Mars from orbit in late 2006. Each one reveals shapes 
of features down to sizes smaller than a tennis court, in a swath of ground 
about 18.6 miles (30 kilometers) wide.

"Reaching 99.1-percent coverage has been tricky because a number of factors, 
including weather conditions, coordination with other instruments, downlink 
limitations, and orbital constraints, tend to limit where we can image 
and when," said Context Camera Team Leader Michael Malin of Malin Space 
Science Systems, San Diego.

In addition to observing nearly the entire planet at least once, the Context 
Camera has observed 60.4 percent of the planet more than once. These 
observations 
aid science directly and also certify the safety of future landing sites.

Malin said, "Single coverage provides a baseline we can use for comparison 
with future observations, as we look for changes. Re-imaging areas serves 
two functions: looking for changes and acquiring stereoscopic views from 
which we can make topographic maps."

A dramatic type of change the Context Camera has documented more than 
200 times is a fresh impact crater appearing between the times of two 
observations. These images enabled scientists to calculate the rate at 
which small asteroids, or bits of comets, are colliding with Mars. Some 
of the fresh impacts reveal white material interpreted as water ice. The 
latitudes and estimated depths of the ice-exposing craters provide evidence 
about the distribution of buried ice near the surface. MRO's Shallow Radar 
has found ice farther underground, but this very shallow ice would go 
undetected if not for its exposure by impacts.

One of MRO's other cameras, the High Resolution Imaging Science Experiment 
(HiRISE), can zoom in on the new impact craters found by the Context Camera. 
For some of these craters, HiRISE and MRO's Compact Reconnaissance Imaging 
Spectrometer for Mars have confirmed the presence of water ice. However, 
even though MRO has returned more than 300 terabits of science data, the 
much higher spatial resolution of HiRISE has limited its coverage of Mars' 
surface to about three percent. A third MRO camera, the Mars Color Imager, 
observes almost the entire planet every day to track weather change. Another 
instrument, the Mars Climate Sounder, records vertical profiles of the 
atmosphere's temperatures and suspended particles.

The spacecraft was launched Aug. 12, 2005. It entered an elongated orbit 
of Mars in March 2006, then spent several months using friction with Mars' 
upper atmosphere to revise its orbit. Since beginning its science operations 
in November 2006, MRO has been flying near-polar orbits lasting about 
two hours, at altitudes from 155 to 196 miles (250 to 316 kilometers). 
The mission completed its 50,000th orbit on Monday, March 27.

"After 11 and a half years in flight, the spacecraft is healthy and remains 
fully functional," said MRO Project Manager Dan Johnston at NASA's Jet 
Propulsion Laboratory, Pasadena, California. "It's a marvelous vehicle 
that we expect will serve the Mars Exploration Program and Mars science 
for many more years to come."

On March 22, the mission made the latest adjustment to the orbit, with 
a 45.1-second burn of six intermediate-size rocket engines, each of which 
provides 5 pounds (22 newtons) of thrust. This maneuver revised the orbit 
orientation, so that the spacecraft can be at the right place at the right 
time, on Nov. 26, 2018, to receive critical radio transmissions from NASA's 
InSight Mars lander as it descends to the surface.

MRO has already provided more than 60 images from HiRISE for advance analysis 
of the landing region for InSight. In a broad plain of the Elysium Planitia 
region of equatorial Mars, InSight
