A sampling of links to recent space policy, politics, and government (US and international) related space news and resource items that I found of interest:
While the Opportunity rover isn’t officially dead yet, at this point engineers seem to be struggling to get communications restored. It’s possible there could be a eureka moment, but for now Oppy remains silent. We chat about our favorite Opportunity Science, Moments and even enjoy the launch itself.
This week we also chat about Stratolaunch history and Future (by way of community vote), Blue Origin Test Flights and Onboard Science and the recent higher-resolution picture of Ultima Thule from New Horizons.
Space news is now presented by TMRO in a separate video:
This is your space news update for January 30th, 2019. Our Space Mike hologram is back, in non hologram form this week to deliver Launch Minute as well as an update on the SpaceX DM-1 mission. We also chat about the recent Blue Origin Test Flight and the ground breaking for their new engine production facility. OneWeb may have access to a lower cost ground based system for their upcoming satellite constellation. And finally, a quick update on NASA’s Opportunity Rover.
Dr. Rose Jones of Bigelow Lab for Ocean Sciences joins us on TMRO.Science to talk about Deep-sea microbial communities, extremophiles and bioremediation of acid mine drainage sites. How these systems all interact and can be used to help break down ocean waste.
A science paper released today and available for download [pdf] cites evidence from about two dozen deep impact craters located from the equator to 37 degrees north latitude that Mars has a ground ice table at an elevation that also corresponds to other shoreline features.
…
The third take-away from this paper however is possibly the most important. The evidence suggests that this deep groundwater water table (as ice) almost certainly still exists at all latitudes, though almost entirely underground. From a future explorer’s perspective, this data reinforces the possibility that water will be accessible across much of the Martian surface. All you will have to do is dig a well, something humans have been doing on Earth for eons.
NASA’s Curiosity rover has taken its last selfie on Vera Rubin Ridge and descended toward a clay region of Mount Sharp. The twisting ridge on Mars has been the rover’s home for more than a year, providing scientists with new samples — and new questions — to puzzle over.
On Dec. 15, Curiosity drilled its 19th sample at a location on the ridge called Rock Hall. On Jan. 15, the spacecraft used its Mars Hand Lens Imager (MAHLI) camera on the end of its robotic arm to take a series of 57 pictures, which were stitched together into this selfie. The “Rock Hall” drill hole is visible to the lower left of the rover; the scene is dustier than usual at this time of year due to a regional dust storm.
Curiosity has been exploring the ridge since September of 2017. It’s now headed into the “clay-bearing unit,” which sits in a trough just south of the ridge. Clay minerals in this unit may hold more clues about the ancient lakes that helped form the lower levels on Mount Sharp.
Engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have begun transmitting a new set of commands to the Opportunity rover in an attempt to compel the 15-year-old Martian explorer to contact Earth. The new commands, which will be beamed to the rover during the next several weeks, address low-likelihood events that could have occurred aboard Opportunity, preventing it from transmitting.
The rover’s last communication with Earth was received June 10, 2018, as a planet-wide dust storm blanketed the solar-powered rover’s location on Mars.
“We have and will continue to use multiple techniques in our attempts to contact the rover,” said John Callas, project manager for Opportunity at JPL. “These new command strategies are in addition to the ‘sweep and beep’ commands we have been transmitting up to the rover since September.” With “sweep and beep,” instead of just listening for Opportunity, the project sends commands to the rover to respond back with a beep.
“With our 16th science flyby, we will have complete global coverage of Jupiter, albeit at coarse resolution, with polar passes separated by 22.5 degrees of longitude,” said Jack Connerney, Juno deputy principal investigator from the Space Research Corporation in Annapolis, Maryland. “Over the second half of our prime mission — science flybys 17 through 32 — we will split the difference, flying exactly halfway between each previous orbit. This will provide coverage of the planet every 11.25 degrees of longitude, providing a more detailed picture of what makes the whole of Jupiter tick.”
Launched on Aug. 5, 2011, from Cape Canaveral, Florida, the spacecraft entered orbit around Jupiter on July 4, 2016. Its science collection began in earnest on the Aug. 27, 2016, flyby. During these flybys, Juno’s suite of sensitive science instruments probes beneath the planet’s obscuring cloud cover and studies Jupiter’s auroras to learn more about the planet’s origins, interior structure, atmosphere and magnetosphere.
“We have already rewritten the textbooks on how Jupiter’s atmosphere works, and on the complexity and asymmetry of its magnetic field,” said Scott Bolton, principal investigator of Juno, from the Southwest Research Institute in San Antonio. “The second half should provide the detail that we can use to refine our understanding of the depth of Jupiter’s zonal winds, the generation of its magnetic field, and the structure and evolution of its interior.”
