In an annual report to Congress, the U.S. Office of the Secretary of Defense has issued: Military and Security Developments Involving the People’s Republic of China 2015.
“China possesses the most rapidly maturing space program in the world and is using its on-orbit and ground-based assets to support its national civil, economic, political, and military goals and objectives,” the report observes.
As recognized in the report, noteworthy 2014 accomplishments for China’s space program include:
— First Sub-meter Resolution Imager: Following its launch in August, the Gaofen-2 became China’s first satellite capable of sub-meter resolution imaging. China reportedly plans to use the satellite for a variety of purposes, including the sale of commercial imagery.
— Lunar Sample-Return Technology Test: In late October, China launched the Chang’e-5 test spacecraft. This mission will test technologies related to retrieving and returning a lunar sample to Earth. China plans to launch the actual Chang’e-5 Lunar Sample Return mission in 2017.
— Fourth Space Launch Center Complete: China completed construction of the Wenchang Space Launch Center (SLC) on Hainan Island in 2014 and plans to begin launching its next-generation Long March-5 and Long March-7 Space Launch Vehicles (SLVs) from the facility no later than 2016.
The report also underscores China’s military space prowess: “In parallel with its space program, China continues to develop a variety of capabilities designed to limit or prevent the use of space-based assets by adversaries during a crisis or conflict, including the development of directed-energy weapons and satellite jammers.”

NASA’s Curiosity Mars rover has recorded a sequence of views of the Sun setting at Gale Crater.Using its Mast Camera (Mastcam), the robot recorded the sunset during an evening of skywatching on April 15, 2015 – at the close of the mission’s 956th Martian day, or sol. They were transmitted back to Earth last week from the Mars machinery.
The imaging was done between dust storms. Some dust remained suspended high in the atmosphere. The sunset observations help researchers assess the vertical distribution of dust in the thin Martian atmosphere.

Meanwhile, in a mission update from the USGS Astrogeology Science Center’s Ryan Anderson, Curiosity recently was stopped on its Sol 978 drive after going only a couple meters instead of the expected roughly 60 feet (19 meters).The reason was that the rover detected that its wheels were slipping in the sand.
“Curiosity currently is in no danger of getting stuck,” Anderson reports, and the weekend plan is to back up slightly and drive around the worst of the sand.
Anderson is a planetary scientist at the USGS Astrogeology Science Center and a member of Curiosity’s ChemCam team.

The errant Russian supply ship intended to link up with the International Space Station has made a destructive plunge to Earth.
The United States Strategic Command (USSTRATCOM) pegged the Progress 59 fall to Earth on May 8 at 02:20 UTC, within a 1 minute window.
According to a European Space Agency (ESA) Internet posting, the final time of the Progress reentry corresponds to an altitude of around 50 miles (80 kilometers), so, roughly, 10 minutes from touchdown.
“This would have been the point in time where the re-entering object was the hottest and so observable from space. This time also corresponds to a location of 51 Degrees South latitude and 273 Degrees East longitude, over the ocean west of the southern tip of the coast of Chile,” explained the ESA statement.
The spin you’re in!
The uncrewed Progress 59 cargo craft – packed with tons of equipment, food, water and propellant — was boosted spaceward April 28 atop a Soyuz launcher, headed for a docking with the ISS.
Shortly after launch, however, the vessel experienced technical woes, going into a spin – perhaps the result of a problem with the Soyuz booster’s third stage.

The fate of the out-of-control Russian Progress supply ship is near-at-hand.
The logistics spacecraft — Progress M-27M — was launched by a Soyuz booster April 28 from Area 31 of the Baikonur launch site at 10:09:50 Moscow Time.
As a resupply ship stocked with tons of cargo and fuel, it was headed for the International Space Station (ISS). The Progress was to use a “quick” 4-orbit flight profile of 6 hours duration to rendezvous with the orbiting outpost.
Shortly after launch, however, the Progress suffered a control problem – possibly due to a malfunctioning Soyuz upper stage, with this onboard video showing the spin-rate of the spacecraft.

Re-entry time
According to European Space Agency (ESA) spokesman, Daniel Scuka, in a May 7 posting:
“ESA space debris team reentry predictions now show the reentry window has shrunk to include just the night of Thursday/Friday, 7/8 May; we can exclude any time after early Friday morning. There are some first indications that the likelihood for a reentry over North America or Europe has dropped significantly.”
Sky observers are keeping a vigil on the soon-to-de-orbit Progress, such as this image from the Brazilian Meteor Observers Network (BRAMON) as the errant craft flew overhead.

Coming night
Holger Krag, Head of the ESA/European Space Operations Center’s Space Debris Office in Darmstadt, Germany: “We expect the re-entry to occur in the coming night.”
Krag told Inside Outer Space that “we have seen the probability dropping for North America and Europe to be affected.”
Given the eminent re-entry of Progress, Russia had not requested involvement of the Inter-Agency Space Debris Coordination Committee (IADC), Krag said.
The primary purposes of the IADC are to exchange information on space debris research activities between member space agencies, to facilitate opportunities for cooperation in space debris research, to review the progress of ongoing cooperative activities, and to identify debris mitigation options.
Roscosmos, the Russian Federal Space Agency, is a member of IADC.

Round and round it goes…exactly when and where it will plummet to Earth is a guessing game.
On April 28, Russia’s uncrewed Progress M-27M supply ship streaked into orbit atop a Soyuz launcher, intended to dock with the International Space Station (ISS).
But shortly after liftoff, the vessel experienced technical difficulties. Subsequently, a Russian mission control team could not command the cargo vessel packed with nearly three tons of supplies.
Here’s the latest, with some surprises as reviewed in my new Space.com story.

Features called recurrent slope lineae (RSL) have been spotted on some Martian slopes in warmer months. Some scientists think RSL could be seasonal flows of salty water. Red arrows point out one 0.75-mile-long (1.2 kilometers) RSL in this image taken by NASA’s Mars Reconnaissance Orbiter.

Orbiting spacecraft of Mars have imaged over the past several years dark, finger-like features – now called “recurring slope lineae” – or RSL for Martian short-hand.
These dark flows have been observed at low and middle latitudes on Mars.
RSL’s are a type of feature that creep down some Martian slopes in warmer months and then fade away in cooler months.
Scientists conjecture that RSL’s may be seasonal flows of salty water.
Indeed, new research reveals the prospect that NASA’s Mars rover, Curiosity, may be within range of active slope processes that resemble RSL, possibly caused by liquid water.
Gale is an expansive crater that measures about 96 miles (154 kilometers) across. Hundreds of exposed rock layers within Gale Crater form Mount Sharp, a mound as tall as the Rockies.

But what caution should be taken in investigating an RSL feature – in terms of planetary protection of Mars? Are they the best place to search for extant (existing) Martian life?
High-resolution repeat imaging
In the journal Icarus, an article is to appear this July — but now available via Icarus in press — titled “Slope activity in Gale crater, Mars.”
The paper is authored by Colin Dundas, a planetary scientist at the U.S. Geological Survey’s Astrogeology Science Center at Flagstaff, Arizona and Alfred McEwen, of the University of Arizona, principal investigator for the super-powerful High Resolution Imaging Science Experiment onboard NASA’s Mars Reconnaissance Orbiter now circling the Red Planet.
“High-resolution repeat imaging of Aeolis Mons, the central mound in Gale crater, reveals active slope processes within tens of kilometers of the Curiosity rover,” they report. “At one location near the base of northeastern Aeolis Mons, dozens of transient narrow lineae were observed, resembling features (Recurring Slope Lineae) that are potentially due to liquid water. However, the lineae faded and have not recurred in subsequent Mars years.”
Potential special regions
Dundas and McEwen state they have not identified confirmed RSL at Gale crater. The researchers note that it has been recommended by astrobiology specialists that RSL “be treated as potential special regions for planetary protection.”
Furthermore, repeat images acquired from above as Curiosity wheels toward the base of Aeolis Mons could spot changes due to active slope processes, “which could enable the rover to examine recently exposed material,” Dundas and McEwen add.
“There is no strong evidence for RSL in Gale,” McEwen told Inside Outer Space.
However, let’s say that Curiosity — or a future lander/rover — does face an RSL situation. What should be done given planetary protection concerns?
It’s McEwen’s opinion to drive up to it and monitor an RSL from as close as possible, he said. The robot is armed with science gear to take a look, he said, particularly using the ChemCam instrument suite to provide remote compositional information using the first laser-induced breakdown spectrometer (LIBS) on a planetary mission.
RSL occur on greater than 25 degree slopes, McEwen advised, “so the rover isn’t going to contact an RSL.”
Greenhouse effect
“The planetary protection is a huge issue especially as we keep finding more and more RSL sites,” now up to 172, said David Stillman, a scientist at the Southwest Research Institute in Boulder, Colorado.
This nearly global mosaic of observations made by the Mars Color Imager on NASA’s Mars Reconnaissance Orbiter on Nov. 18, 2012, shows a dust storm in Mars’ southern hemisphere. Small white arrows outline the area where dust from the storm is apparent in the atmosphere. From decades of observing Mars, scientists know there is a seasonal pattern to the largest Martian dust-storm events.

Stillman’s Mars research, for instance, has taken him to an RSL site in Valles Marineris, suggesting that it is recharged by an aquifer. The total amount of water liberated from the area equals 8 to 17 Olympic-sized swimming pools, he said, and the only way to annually recharge such a large volume of water is via an aquifer.
Stillman told Inside Outer Space that it is very interesting that the RSL-like features at Gale only occurred after the MY28 dust storm.
“While we didn’t even know what to look for in MY28 [Mars Year starting in mid-June and ending in early December 2007], we luckily imaged many RSL sites,” Stillman said. Nearly all of them, he said, had many more individual RSL and the RSL were much longer.
“We have a theory that the dust storm actually produced a slight greenhouse effect that increased subsurface warming,” Stillman concluded.

According to Ken Herkenhoff of the U.S. Geological Survey (USGS) in Flagstaff, Arizona, NASA’s Curiosity rover on Mars is now in a good position for contact science observations on an interesting outcrop of sedimentary rock.
On Sol 973, the rover is using several instruments to observe nearby targets “Albert” and “Charity,” and a distant target named “Empire.”
Also, the rover will use its Navcam will search for Martian clouds and dust devils.

NASA’s Curiosity rover is “factory loaded” with the biggest, most advanced suite of instruments for scientific studies ever sent to the Martian surface.
The record of the planet’s climate and geology is essentially “written in the rocks and soil” — in their formation, structure, and chemical composition.

A scientific and public campaign is underway to keep operating NASA’s Lunar Reconnaissance Orbiter (LRO) and the Opportunity Mars rover.
Both have been zeroed out in the President’s FY16 budget for NASA. This is despite LRO and Opportunity being highly ranked in a recent “Senior Review” of planetary missions.
LRO was launched in 2009; Opportunity has been on duty on Mars since its landing in early 2004.

But there is an even deeper issue that is being expressed by the letter-writing campaign.
That is, the role of the independent review process within NASA’s budget decisions.
Furthermore, why have senior reviews in the first place, followed by the Office of Management and Budget (OMB) decisions to cut those missions anyway?
Recommendations rejected
“It is hoped that a strong show of support from the planetary — and specifically the lunar community — will demonstrate to our elected officials the backing these planetary missions have,” explains lunar researcher, Clive Neal of the Dept. of Civil & Environmental Engineering & Earth Sciences at the University of Notre Dame in Indiana.
In a letter to the scientific community, requesting signatures of support, the communiqué explains that “we were greatly surprised” by the President’s FY 2016 budget request for NASA, which proposed to defund continued operations of both Opportunity and the LRO.

“This decision rejects the recommendations made by the planetary senior review process. These two missions were among the most highly ranked in the Report – only the Cassini mission at Saturn was judged as having a better science return,” the letter explains.
“We urge Congress to support the results of this independent review process and to augment NASA’s budget to continue operating its fleet of high-performing, scientifically valuable planetary spacecraft,” the letter concludes.

Public outreach
Also engaged in activating a public response to these issues is The Planetary Society.
“Here at The Planetary Society, we’ve been gathering petitions from our members and the wider community for LRO/Opportunity since early March,” explains Casey Dreier, Director of Advocacy for the organization.
Dreier advised Inside Outer Space that the URL below is perfect for the public to get engaged about supporting these missions. It sends a message directly to representatives in Congress, he said, with a default letter (which can be modified) that contains a focus on the cancelled missions within the context of planetary exploration.
Letters will be sent to the congressional people that sit on the committees that oversee NASA’s budget.

New imagery shows the robot taking hits to its wheels, including a lodged rock in one wheel.
After landing on Mars Aug. 5, 2012 (California time), Curiosity spent much of its first 12 months on the Red Planet studying locations close to its landing site north of Mount Sharp.
Findings during that period and subsequent treks continue to gather evidence for ancient rivers and a lakebed environment that offer conditions favorable for microbial life – if Mars has ever hosted life.
