The competition heats up: SpaceX has successfully put two commecial satellites in orbit. The first stage hit the barge, but the landing was unsuccessful. More details to come.
The full video of the entire launch is embedded below the fold. One interesting part includes a view from inside the first stage looking back at the second stage at separate, followed with images from the first stage on its way back to Earth..
After almost a year exploring Marathon Valley, an east-west cut through the western rim of Endeavour Crater, the Mars rover Opportunity is about to head out and south, following the outside of the crater’s rim.
For a rover that was only supposed to last 90 days, Opportunity has now traveled more than 26.5 miles in its 12 years of operation on the Martian surface.
A deal struck today by Senator John McCain (R-Arizona) will allow ULA to buy 18 more Russian engines for its Atlas 5, instead of the limit of nine that McCain had previously demanded.
The deal also includes a deadline of 2022, after which no more Russian engines can be purchased, even if some of the 18 have not yet been bought.
The competition heats up: SpaceX will attempt another commercial launch on Wednesday morning, this time putting two satellites into orbit.
They will once again try to land the first stage in what they say are difficult circumstances. They are also picking up the launch pace, with this the second commercial launch in less than three weeks. It will also be their sixth launch of the year, matching what they did in each of the last two years, with more than half the year to go.
The competition heats up: China announced plans today to send its next lunar lander, Chang’e 4, to the Moon’s farside south pole in 2018.
The lander of Chang’e-4 will be equipped with descent and terrain cameras, and the rover will be equipped with a panoramic camera, he said. Like China’s first lunar rover Yutu, or Jade Rabbit, carried by Chang’e-3, the rover of Chang’e-4 will carry subsurface penetrating radar to detect the near surface structure of the moon, and an infrared spectrometer to analyze the chemical composition of lunar samples.
But unlike Chang’e-3, the new lander will be equipped with an important scientific payload especially designed for the far side of the moon: a low-frequency radio spectrometer. “Since the far side of the moon is shielded from electromagnetic interference from the Earth, it’s an ideal place to research the space environment and solar bursts, and the probe can ‘listen’ to the deeper reaches of the cosmos,” Liu said.
The U.S. had been in the lead in the land rush to gain dominance in the possibly water-rich lunar south pole. We apparently have lost this lead with decision of President Obama and Congress to focus elsewhere, either the asteroids or Mars.
After four years of southwest travel to skirt a large dune field at the base of Mount Sharp, Curiosity has finally turned due south to aim directly up the mountain.
“Now that we’ve skirted our way around the dunes and crossed the plateau, we’ve turned south to climb the mountain head-on,” said Curiosity Project Scientist Ashwin Vasavada, of NASA’s Jet Propulsion Laboratory, Pasadena, California. “Since landing, we’ve been aiming for this gap in the terrain and this left turn. It’s a great moment for the mission.”
During Rosetta’s recent close approaches to Comet 67P/C-G scientists were able to confirm the presence of two noble gases, krypton and xenon.
Rosetta had already detected argon, which makes three of the six noble gases.

A fire in space: Orbital ATK’s Cygnus capsule is scheduled to leave ISS on Tuesday, when shortly thereafter it will begin a controlled fire experiment.
“Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions. – See more at: http://www.space.com/17933-nasa-television-webcasts-live-space-tv.html#sthash.2DjFjJqY.dpuf
The departure is scheduled for 9 am (eastern), and will aired live by NASA.
5 Unintended Consequences of Windows 10 Upgradegate
The bottom line: Microsoft’s culture has always been that of an immoral bully who has no ethics, even when they created good software (which was not often). Why anyone would continue to rely on them baffles me completely.
Cool image time! The picture below, taken by Cassini in April, looks down at Saturn’s vast rings and shows a disruption in Saturn’s outermost F ring, likely caused by an interaction of objects within the ring.
The competition heats up: Blue Origin’s fourth test flight of its New Shepard suborbital spacecraft will take place this Friday, and will be webcast live.
No time announced yet, but the place to see it will be the Blue Origin website.
The competition heats up (but not in the way you think): NASA and the United Arab Emirates (UAE) space agency have signed an agreement to cooperate in space research and technology development.
The agreement covers cooperation and collaboration in space science, operational Earth observation and Earth science, aeronautics, space operations and exploration, education, technology, safety and mission assurance, and other areas with potential benefits to all nations.
The two countries will continue to identify additional areas of mutual interest for possible future cooperative programs or joint activities on Earth, in airspace, or in outer space. These activities may include the joint use of aircraft, scientific instruments aboard spacecraft, ground-based research facilities, spacecraft and space research platforms, as well as ground-based antennas for tracking, telemetry, and data acquisition. Additionally, the two countries will aim to collaborate on the creation and implementation of education and public outreach programs and joint workshops, with the goal of facilitating the exchange of scientific data, scientists, engineers, and views and experiences on relevant regulatory frameworks and standards.
The competition here is not between these big space government programs, who are increasingly teaming up, but between the big space government programs and the profitable and uncontrolled private sector. I fully expect there to be more calls for government supervision and licensing of private space, just to control it better. And what better way to leverage that control but to link every big space program in the world together, so that there are no independent efforts?
The competition heats up: ULA today successfully launched a U.S. National Reconnaissance Office spy satellite, using what is presently the world’s most powerful rocket, the Delta 4 Heavy.
In many ways, this rocket’s launch, which you can see in the video embedded below the fold, gives a rough idea of what a Falcon Heavy launch will look like, since the rockets have somewhat similar configurations.

The competition heats up: A Polish company has developed a gun for firing a net to capture space junk, and has demonstrated its operation by capturing a flying drone at a space junk conference.
There is a video at the link showing the capture. They have also tested this technology on a vomit comet, and hope to launch a full scale model by 2023.
The competition heats up: In an interview with the Washington Post this week, Elon Musk gave some more hints at his company’s future plans to send its Dragon capsules to Mars.
“Essentially what we’re saying is we’re establishing a cargo route to Mars,” [Musk] said. “It’s a regular cargo route. You can count on it. It’s going happen every 26 months. Like a train leaving the station. And if scientists around the world know that they can count on that, and it’s going to be inexpensive, relatively speaking compared to anything in the past, then they will plan accordingly and come up with a lot of great experiments.”
The key to Musk’s effort is that he plans on doing it. He isn’t sitting around waiting for others, or trying to convince others to join him in a partnership before proceeding. He is simply doing it, and is welcoming others to take advantage of the opportunity he is offering.
Cool image time! The picture on the right, taken by New Horizons during its July 2015 flyby and cropped and reduced here, shows the reddish hues of the Krun Macula dark region along the shore of Pluto’s vast nitrogen ice plains. The hillsides here rise about a mile and a half above both the plains and the valleys, making them deeper than the Grand Canyon. The hills are “believed to get its dark red color from tholins, complex molecules found across Pluto.”
The competition heats up: One group of mobile broadband companies is fighting another group of satellite-based internet companies for control over the use of a part of the electromagnetic spectrum.
A coalition of 5G terrestrial mobile broadband companies led by Charlie Ergen’s Dish Network on June 8 asked U.S. regulators to strip future low-orbiting satellite Internet constellations of their priority access to 500 megahertz of Ku-band spectrum – spectrum coveted by prospective constellation operators including OneWeb LLC and SpaceX. SpaceX and satellite fleet operator Intelsat, a OneWeb investor and partner, immediately filed separate opposition papers to the FCC, arguing that nongeostationary-orbit (NGSO) constellations are very much alive.
In the middle is the FCC and our hapless and increasingly corrupt federal government. I sadly suspect the side that will win this battle will be the side that gives the most campaign money to the right politicians.
For reasons that are not yet clear, either the first or the second stage of Russia’s Proton, launched today, underperformed, requiring the Breeze-M upper stage to compensate in order to get the commercial satellite into the proper orbit.
This is the same thing that happened on the last Soyuz rocket launch, with no explanation as yet either.
The competition cools down? A regulatory agency in India is proposing eliminating commercial satellite competition and consolidating all satellite television broadcasts onto a handful of government owned and launched satellites.
Indian Prime Minister Narendra Modi’s “Make in India” campaign seeks to promote India’s domestic industrial base. The Telecom Regulatory Authority of India (TRAI) on May 23 published what it calls a “pre-consultation paper” that points to the savings satellite-television broadcasters could realize if they stopped beaming the same programs on different satellites, and instead banded together on one or two spacecraft.
As of March 2015, the latest period for which TRAI has produced figures, there were 76 million DTH subscribers in India, of which 41.1 million were considered active. These subscribers received programming from six pay TV DTH providers and one free-to-air satellite broadcast service. TRAI said multiple DTH providers are broadcasting the same channels even as they compete with each other for subscribers. “There is scope for better utilization of available infrastructure,” TRAI said. “There is a need to examine technical and commercial issues in sharing of infrastructure such as satellite transponders, Earth station facilities….”
There is also this important component to the story:
India has been one of the biggest satellite-DTH growth markets in recent years, but one in which barriers to entry by foreigners remain high. Under Indian law, television broadcasters seeking operating licenses are given preferential treatment if they use India’s own Insat telecommunications satellites, owned and operated by the Indian Space Research Organization (ISRO). Non-Indian satellites are permitted if ISRO’s Insat system does not have sufficient capacity to meet programmers’ demand. This has been the case for years as ISRO has been unable to keep up with the market for satellite television.
In other words, the commercial satellite business in India is doing great, so let’s muck it up by having one government agency create a monopoly for another government agency.
The United States tried this in the 1960s when it banned private companies from launching commercial communications satellites and instead required all such satellites to be built by the government-managed Comsat corporation. The result in the U.S. was a squelched satellite and launch industry that did not recover for more than a decade, and only did so when the Nixon administration forced a change in the rules.
