SpaceX is moving its Grasshopper test program to New Mexico’s spaceport.

The move confirms big plans for the test bed. Flights to date have been conducted at SpaceX’s engine test site in McGregor, Texas. SpaceX received a waiver from the FAA to fly Grasshopper up to 11,500ft from McGregor, but Spaceport America is an FAA-certified spaceport where no where no waivers are required. “Spaceport America offers us the physical and regulatory landscape needed to complete the next phase of Grasshopper testing,” says SpaceX president Gwynne Shotwell.

Japan’s entire space program faces a major overhaul.

12:59 am

Feeling the heat of competition: Japan’s entire space program faces a major overhaul.

In the last few decades Japan has not done very well in space when compared to other Asian countries like China and India. Thus, this overhaul. Yet, based on this article, it doesn’t seem to me that they are making the real changes they need to do to successfully compete. If anything, it sounds instead like the actions of a bureaucracy that is merely rearranging the deck chairs on a sinking ship, in the hope that this will somehow save it.

The 2000th show

12:45 pm

Tonight David Livingston will air the 2000th episode of The Space Show, what has become the world’s leading media outlet for the discussion of space exploration and the aerospace industry.

The Space Show began in June 2001, and in the ensuing dozen years David has interviewed almost every single big mover in the business of space exploration. I myself have been honored to appear on his show more than thirty times, a fact for which I am deeply grateful, since there are people far more important than I in this field.

It is difficult to measure the significance to space of David Livingston’s effort during these past twelve years. When the Space Show began, SpaceShipOne had not yet flow, the X-Price had not yet been won, and the idea of private space and space tourism were considered wild and absurd ideas. Twelve years later, these ideas are now common knowledge and are likely to be main path for the human race into space. By giving a forum to supporters of commercial space, the Space Show under David’s leadership made this paradigm shift possible.

Thank you David! When the solar system is finally settled, the colonists should remember that without his important contribution their journey to get there would have been far more difficult.

The three phonesats launched piggyback on Antares several weeks ago beamed down images of Earth that have now been released.

The three phonesats launched piggyback on Antares several weeks ago beamed down images of Earth that have now been released.

The three cube-shaped satellites were launched on Sunday, April 21, 2013 atop Orbital Science Corporation’s Antares rocket from NASA’s Wallops Island Flight Facility in Virginia. The three satellites were all built around a standard cubesat frame about four inches (10 cm) square, with a larger, external lithium-ion battery and a radio powerful enough to reach Earth. The smartphone components not only provided cameras for snapping pictures of the Earth, but also acted as the spacecrafts’ avionics for maintaining attitude control.

In keeping with the PhoneSat’s mission’s goal of getting into space on a budget, the images were transmitted back to Earth in the form of image-data packets that were received not just by NASA’s Ames Research Center but also by amateur radio operators around the world, who volunteered their services to collect 200 of these packets.

Private space is winning

11:50 pm

Today I attended an space industry conference here in Orange County, California, sponsored by the American Institute of Aeronautics and Astronautics. Unlike the Space Hackers conference which also occurred today and to which I was also invited, this was not a New Space get-together, but a standard aerospace event which included a lot of old time engineers from the big old-time companies like Boeing and Lockheed Martin.

Most of the talks today were engineering related. For example, one described in detail the engineering advantages of building ion engines and solar sails at the molecular level, nanotechnology to the max. Another talk, which I found astonishing and exciting, was an analysis of the orbital mechanics of getting to Mars. This analysis found that using constant acceleration as low as .01 G it would be possible to get to Mars in weeks, not years, and without the necessity of waiting for the perfect launch window. You could launch almost anytime. Though we don’t have engines that as yet can provide this much constant low acceleration, these numbers are not so high as to make it impossible. With some clever refinements, it might be possible to come up with propulsion systems capable of these constant Gs, and to do it in the near future. If so, it will open up the entire solar system to manned exploration very quickly. Not only will we be able to travel to the planets in a reasonable time, the constant Gs would overcome the medical problems caused by prolonged weightlessness.

It wasn’t these interesting engineering presentations that got my juices flowing however. Instead, it was presentation on public policy issues that completely surprised me and made me think the future of the American aerospace industry is really going in the right direction. This significant take-away was further reinforced by the audience’s reaction to my lecture in the evening.

The robotic demonstration of remote satellite repair on ISS resumed this week.

The latest round of demos follows a breakthrough round of ground-controlled activities in January using the 70-ft.-long Canadian robot arm/Dextre combination to sever lock wires and remove a mock fuel cap to flow 1.7 liters of ethanol fuel into the RMM.

The new tests will see if the robot arm can do even finer and more difficult tasks, such as unscrewing and storing a small screw.

The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

9:10 am

The European Space Agency is investigating the possibility that the Progress docking to ISS on April 26 might have damaged equipment needed by their ATV cargo ship.

The damage, caused by the undeployed Progress antenna, appears to have involved a navigational aid needed for ATV-4 … the Laser Radar Reflector (LRR) target. The LRR is needed for the automatic docking of the European ATV during the last part of the rendezvous operations. If the damage is confirmed, the device, recently replaced during an EVA by the Russian crew due to contamination of the optical section, will need to be replaced again. In this event, the European cargo ship could potentially be delayed for several months. ATV-4, named Albert Einstein, has been already delayed from April to June because of a glitch in an avionics box.

NASA revealed Tuesday that last April the Fermi Gamma-Ray Telescope barely avoided a collision with an abandoned Russian satellite.

NASA revealed Tuesday that last April the Fermi Gamma-Ray Telescope barely avoided a collision with an abandoned Russian satellite.

Fermi mission scientists first learned of the space collision threat on March 29, 2012 when they received a notice that the space telescope and Cosmos 1805 would miss each other by just 700 feet (213.4 meters). The mission team monitored the situation over the next day and it became clear that the two spacecraft, traveling in different orbits, would zip through the same point in space within 30 milliseconds of one another, NASA officials said.

They used Fermi’s thrusters to shift its orbit enough so the two spacecraft missed each other by 6 miles.

In a NASA contest, a nine-year-old has named asteroid 1999 RQ36 after the Egyptian god Bennu.

10:44 am

A rose by any other name: In a NASA contest, a nine-year-old has named asteroid 1999 RQ36 after the Egyptian god Bennu.

1999 RQ36, or Bennu, is an important asteroid for two reasons. First, NASA is sending an unmanned sample return mission to it in 2016. Second, some calculations suggest the asteroid has a 1 in a 1000 chance of hitting the Earth in 2182.

In other naming news, the private space company Uwingu has launched its “Adopt-a-Planet” campaign.

This open-ended campaign gives anyone in the public—worldwide—the opportunity to adopt exoplanets in astronomical databases via Uwingu’s web site at www.uwingu.com. Proceeds from the naming and voting will continue to help fuel new Uwingu grants to fund space exploration, research, and education.

As noted earlier, they are ignoring the IAU’s stuffy insistence that only the IAU can name things in space.

In NASA’s new contract with Russia to launch astronauts to ISS Russia has raised the ticket price from $63 million to $70.6 million per seat.

1:23 pm

The competition heats up: In NASA’s new contract with Russia to launch astronauts to ISS, announced today, Russia has raised the ticket price from $63 million to $70.6 million per seat.

Since the fall of the Soviet Union the Russians have become very good capitalists indeed. Consider: the price the Russians were charging for a single ticket on Soyuz was about $33 million in 2004, when George Bush announced the planned retirement of the shuttle. Since then they have repeatedly jacked up the price, knowing that we have no where else to go.

In the end, these price increases are actually a good thing, as they will make it easier for the new American companies to undercut them while simultaneously making a bigger profit.

Opportunity went into safe mode during the communications pause in April when the Sun was between Mars and the Earth.

8:29 am

Opportunity went into safe mode during the communications pause in April when the Sun was between Mars and the Earth.

Mission controllers for Opportunity, which landed on Mars in January 2004, first learned of the issue on Saturday (April 27). On that day, the rover got back in touch after a nearly three-week communication moratorium caused by an unfavorable planetary alignment called a Mars solar conjunction, in which Mars and Earth are on opposite sides of the sun. The Opportunity rover apparently put itself into standby on April 22 after sensing a problem during a routine camera check, mission managers said.

It sounds like this is a recoverable problem and the rover will be back in operation momentarily. Stay tuned.

A new report from Russia suggests that the undeployed antenna on the Progess freighter will interfere with ISS’s docking port and prevent a docking.

A new report from Russia suggests that the undeployed antenna on the Progess freighter will interfere with ISS’s docking port and prevent a docking.

It appears that the antenna would allow a soft docking but prevent the hard docking necessary to allow for the opening of the hatch. Something similar to this had happened on the Russian Mir station in the 1987. Two astronauts did a space walk to clear the hatch of a piece of debris. Now the Russians are suggesting again that if a hard dock becomes impossible a spacewalk be performed to get the antenna out of the way.

An antenna used to orient a Progress freighter during docking, launched today to ISS, has failed to deploy.

11:14 am

An antenna used to orient a Progress freighter during docking, launched today to ISS, has failed to deploy.

Though astronauts can manually dock the spacecraft, they still need proper radar data to gauge its location, spin, orientation, speed, and distance. If the remaining four antennas cannot provide all this information, it will be very dangerous to try a docking.

A problem like this has not happened on a Progress freighter in literally decades. When I consider the spate of other recent failures experienced by the Russian space industry, I can’t help wondering whether they have developed an overall quality control problem.

Update: Russian mission control said today that even if they cannot solve the deployment failure and get the antenna working it will not prevent a docking with ISS on Friday.

I tend to believe them. With four other antennas plus additional radar equipment on ISS it does seems reasonable that there is sufficient redundancy to allow the docking to proceed. Also, considering the Russians past problems with collisions on Mir, I would expect them to be very careful about proceeding if they had any doubts.

A rocket reveals a fundamental truth about America

12:29 pm

Yesterday, Orbital Sciences successfully completed the first test launch of its Antares rocket, developed, designed, and built in less than five years under a commercial contract with NASA to provide cargo to the International Space Station. The launch went like clockwork, perfectly, with no hitches at all, something that is quite remarkable for a new rocket on its first launch. Kudos to the engineers at Orbital Sciences for a job well done!

Besides demonstrating the skill of Orbital Science’s engineers, however, this successful launch illustrated in stark reality a fundamental fact about the culture of the United States that continues to allow it to stand out from the rest of the world, even as a large percentage of the present generation of Americans are doing their darndest to try to destroy that culture. Moreover, that fundamental cultural fact is basic to human nature, not just the United States, and if we recognize it, it will provide us all the right framework for what to do and not to do in trying to maintain human societies, both here on Earth as well as in the future in space.

In order to understand the true significance of Orbital Sciences’s success yesterday with Antares, however, we must first review the capabilities of the world’s launch industry. I am not going to list all the rockets capable of putting payloads into orbit, only those that are successfully competing for business in the open commercial market.
