India’s Mangalyaan Mars probe has returned its first image, a picture of India on Earth.
Though you can always learn something from any image, what is significant here is that before even leaving Earth orbit engineers have proven that the spacecraft’s camera works.
The competition heats up: In a launch today a Russian Dnepr rocket sent 32 satellites into orbit, breaking the record of 29 set less than a week ago by a Minotaur rocket.
This is the future. Satellites are going to get smaller, and thus cheaper to launch.
Dennis Tito’s project to launch a manned fly-by of Mars by 2018 has issued its revised plans, and they call for NASA to use SLS to do it.
I will have more to say about this proposal shortly.
On Sunday Curiosity suffered an electrical problem that has caused a pause in operations while engineers troubleshoot it.
At the moment the rover has ceased its travel. Though they are trying to make this sound as if it isn’t that big a deal, it does not sound good to me.
On Tuesday NASA issued a solicitation for bids on providing the agency a manned ferrying capability to and from ISS.
The new solicitation asks for proposals for final design, development, test, evaluation and certification of a human space transportation system, including ground operations, launch, orbital operations, return to Earth and landing.
The article is unclear how this solicitation fits in with the commercial crew program that already exists and is funding the manned upgrade of SpaceX’s Dragon and the development of Boeing’s CST-100 and Sierra Nevada’s Dream Chaser.
Update: This article makes things much clearer, outlining how this solicitation is the next phase in development and is open to all bidders.
An Orbital Sciences’ Minotaur rocket tonight launched a record 29 satellites into orbit, 28 of which were cubesats.

To save money, NASA management has shut down a troubled program to build a more efficient plutonium power supply for its deep space missions.
The cancelled ASRGs would have generated electrical power from the expansion of gas warmed by the radioactive decay of plutonium-238. NASA says that the devices have the same power output as its current generation of Multi-Mission Radioactive Thermoelectric Generators (MMRTG) but use four times less plutonium-238, a scarce resource. One MMRTG with 4.8 kilograms of plutonium is currently powering the Curiosity rover on Mars.
The United States has less than 40 kilograms of plutonium-238 left, but the DOE restarted production this year. Green says he is confident that the DOE will be producing plutonium-238 at a rate of 1.5 kilograms per year by 2019. He says that the stockpiled plutonium-238, along with the new supply, will be enough to send another planned rover to Mars in 2020 and to complete other missions in the 2020s – without any need for the extra efficiency of the ASRGs.
The ASRG program had been a year and a half behind schedule and had had its management team replaced at one point.
A close look at another government program to try to lower the cost to orbit.
The latest program is know as the Experimental Spaceplane — or XS-1. The objective “is to demonstrate a reusable first stage launch vehicle capable of carrying and deploying an upper stage that inserts 3,000 to 5,000 lb. payloads into Low Earth Orbit (LEO), designed for less than $5M per launch for an operational system.” The system has to be able to perform with aircraft-like operations. And demonstrate the ability to fly 10 times in 10 days. It needs to reach Mach 10 at least once. And provide the basis for next-generation launch services and “global reach hypersonic and space access aircraft.”
Forgive me if I am skeptical. Despite DARPA’s reasonable success (It helped make possible SpaceX’s Merlin engine), these government efforts generally fail because they are unattached to the prime reasons for lowering cost: competition and profits. Consider this very accurate historical summary in the article above:
In the era of bell bottoms and Richard Nixon, there was the space shuttle. When Ronald Reagan ruled the roost, all hope rested in the National Aerospace Plane. During the Bill Clinton era, there were the X-33 and Venture Star. In Barack Obama’s first term, the Air Force pursued its Reusable Booster System (RBS).
Five programs. One objective: to radically reduce the cost to orbit. More than $14 billion spent on development. And the result? A super expensive shuttle program. Four vehicles that never flew. And access to space just kept getting more expensive.
Only when every effort in the aerospace industry is focused on making itself more competitive will we see the kinds of technical advancements this new DARPA program wishes to achieve.
MAVEN has reached orbit.
After an additional engine burn, the spacecraft is now on its way to Mars.
NASA’s next Mars orbiter, MAVEN, is go for launch today at 1:28 pm.
Moreover, another launch on Tuesday night from Wallops Island will be visible along the entire east coast, and will put a record 29 satellites into orbit.
The new head of the Russian Space Agency has requested that the government impose a ban on the sale in Russia of any foreign made satellites.
The idea is that Russian industries should build these satellites instead, and that this ban will encourage the rebirth of the Russian satellite business.
I doubt it. If the Russian satellite business could do it better, they would get the business anyway, especially since their labor costs are generally much lower.
The competition heats up: In the past three months Scaled Composites has conducted nine tests of SpaceShipTwo engines.
It also appears that one test was of an alternative engine to the one they have been planning to use. All told this suggests they are accelerating their effort to finish SpaceShipTwo.
