China’s Tianzhou-1 unmanned freighter today successfully completed its first refueling test to the Chinese station module Tiangong-2.
The two spaceships will remain docked for another two months, followed by two more docking tests.
An evening pause: Hat tip Jim Mallamace, who wrote, “Pietro Mascagni’s ‘Cavalleria Rusticana’ is often translated as ‘Country Ways.’ His opera departed from those of his day in that his characters were not of the nobility. He portrayed the lives and struggles of ordinary people. The performance is by the Gaetano Donizetti Symphonic Orchestra of Gessate and conducted by Pierangelo Pelucchi.”

Government in action! Despite spending almost $19 billion and more than thirteen years of development, NASA today admitted that it will have to delay the first test flight of the SLS rocket from late 2018 to sometime in 2019.
“We agree with the GAO that maintaining a November 2018 launch readiness date is not in the best interest of the program, and we are in the process of establishing a new target in 2019,” wrote William Gerstenmaier, chief of NASA’s human spaceflight program. “Caution should be used in referencing the report on the specific technical issues, but the overall conclusions are valid.”
Anyone who is a regular reader of Behind the Black will not be surprised by this. Beginning as far back as March 2015 I began noting the various issues that made a 2018 launch unlikely. All that has happened here is that NASA has gone public with what has been obvious within the agency now for two years.
The competition between the big government SLS/Orion program and private commercial space is downright embarrassing to the government. While SLS continues to be delayed, even after more than a decade of work and billions of wasted dollars, SpaceX is gearing up for the first flight of Falcon Heavy this year. And they will be doing it despite the fact that Congress took money from the commercial private space effort, delaying its progress, in order to throw more money at SLS/Orion.
Scientists are doing new research at using some form of hibernation for humans traveling on interplanetary missions lasting months or years.
Bradford’s engineering and medical team used the first of those NIAC grants, issued in 2013, to design a compact zero-gravity, rigid-structure habitat based on the International Space Station crew module designs. The habitat featured closed-loop oxygen and water production systems, direct access to the Mars ascent and descent vehicles, and support for a crew of six, all of whom would be kept in torpor for the entire six- to nine-month Mars journey.
The proposed medical treatment relies on using techniques similar to the ones surgeons perfected to induce hypothermia. For example, cooling nitrogen gas could be fed to astronauts via nasal cannula, lowering brain and body temperatures to between 89 and 96 degrees—close enough to normal to maintain torpor without overcooling the heart or increasing the risk of other complications. Cooling tends to decrease the body’s ability to clot, Tisherman says. He has also noted that patients who are cooled to mild levels of hypothermia—93 degrees—for 48 hours or more have more infections than uncooled people.
As is usual in these modern fascist times, bureaucracy and the fear of radical protesters are preventing this research from moving forward. NASA is forbidden to fund any research that uses live animal subjects, such as pigs, even though they are ideal subjects and, as noted in the article, “The number of pigs involved in this kind of study wouldn’t amount to one’s week’s breakfast for the average American.” Private funds have also not raised because no one wants to deal with the public relations nightmare of PETA protests.
The article is long and detailed, and gives an excellent overview of the state of the field as well as the research questions it faces. Above all, it does indicate that the idea of using hibernation in space, born in science fiction, is not so much of a fantasy after all.
The fascists win: A family parade in Portland Oregon has been cancelled because of threats of violence from leftist protesters because the Republican Party was participating.
The participation by local political parties in these kinds of events has been a normal part of American life since the nation’s founding, all based on the first amendment and freedom of speech. To these left wing brown-shirted thugs, however, freedom of speech by their opponents is unacceptable, and requires the threat of violence to shut it down.
Yesterday the space subcommittee of the Senate Commerce committee held a hearing, organized by Senator Ted Cruz (R-Texas), entitled “Reopening the American Frontier: Reducing Regulatory Barriers and Expanding American Free Enterprise in Space.”
You can watch the hearing here. There have also been a number of stories last night and today that summarized the testimony during this hearing.
Having watched the full hearing, I think that most of these stories did not capture well the full political context and significance of yesterday’s event. They focused on Cruz’s advocacy for private space and the call for less and more streamlined regulation by the witnesses. They missed a great deal else.

The space agencies of the United Arab Emirates (UAE) and Algeria have signed an agreement to enhance their collaboration in space.
I didn’t even know Algeria had a space agency.
The Cassini spacecraft has successfully survived its close flyby of Saturn, diving between the rings and the top of the planet’s cloud tops.
As it dove through the gap, Cassini came within about 1,900 miles (3,000 kilometers) of Saturn’s cloud tops (where the air pressure is 1 bar — comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.
Cassini is beaming down its images and data now, with the images to be available later today.
Embedded below the fold. John and I had a lot to catch up on. More to come tomorrow.

The third of four reaction wheels on Dawn failed on April 23, forcing the spacecraft to use its conventional thrusters to orient itself.
The team discovered the situation during a scheduled communications session on April 24, diagnosed the problem, and returned the spacecraft to its standard flight configuration, still with hydrazine control, on April 25. The failure occurred after Dawn completed its five-hour segment of ion thrusting on April 22 to adjust its orbit, but before the shorter maneuver scheduled for April 23-24. The orbit will still allow Dawn to perform its opposition measurements. The reaction wheel’s malfunctioning will not significantly impact the rest of the extended mission at Ceres.
This might shorten Dawn’s remaining mission, but since it is in its final days anyway, the loss will not be severe.
Government in action! A NASA inspector general report has found that NASA’s program for developing new spacesuit is behind schedule, over budget, and unable to provide the necessary spacesuits needed for the agency’s future projects.
NASA’s spacewalking suits are in short supply, and a replacement is still years away despite the nearly $200 million spent on new technology, the space agency’s inspector general reported Wednesday. A next-generation suit for spacewalking astronauts is needed for future space travel, including trips to Mars. But a lack of a formal plan and destinations has complicated suit development, according to the report . At the same time, NASA has reduced funding for suit development, putting more priority instead on space habitats.
According to the report, NASA is dealing with a variety of design and health risks associated with the spacewalking suits used by astronauts aboard the International Space Station. The suits were developed more than 40 years ago and intended for 15 years.
More here. Essentially, the suits NASA presently uses on ISS don’t work well, there aren’t enough of them left, and they are difficult to maintain because they were designed for transport up and down on the space shuttle. At the same time NASA’s entire program to replace these suits has been mismanaged so badly that no replacement suits are anywhere on the horizon,even after spending hundreds of millions of dollars.
I predict that the next new spacesuit Americans use will be built in less than five years for a tenth the cost, by private companies.
