The competition heats up: A new Defense Department report says that China is aggressively ramping up its space program.

China will continue to augment its orbiting assets, with the planned launch of 100 more satellites through 2015. These launches include imaging, remote sensing, navigation, communication and scientific satellites, as well as manned spacecraft.

China is pursuing a variety of air, sea, undersea, space, counterspace and information warfare systems, as well as operational concepts, moving toward an array of overlapping, multilayered offensive capabilities extending from China’s coast into the western Pacific. China’s 2008 Defense White Paper asserts that one of the priorities for the development of China’s armed forces is to “increase the country’s capabilities to maintain maritime, space and electromagnetic space security.”

Further, China continues to develop the Long March 5 rocket, which is intended to lift heavy payloads into space. LM-5 will more than double the size of the Low Earth Orbit (LEO) and Geosynchronous Orbit (GEO) payloads China is capable of placing into orbit. To support these rockets, China began constructing the Wenchang Satellite Launch Center in 2008. Located on Hainan Island, this launch facility is expected to be complete sometime this year 2013, with the initial LM-5 launch scheduled for 2014.

A Russian Bion-M spacecraft, filled with mice, lizards and other animals, returned to Earth after 30 days in space with about half its mice and all its gerbils dead.

A Russian Bion-M spacecraft, filled with mice, lizards and other animals, returned to Earth after 30 days in space with about half its mice and all its gerbils dead.

The Bion-M experiment, launched from Baikonur, Kazakhstan, on April 19, carried 45 mice, 15 geckos, 18 Mongolian gerbils, 20 snails and a number of different plants, seeds and microorganisms, according to a Russian state news site. About half of the mice died, but the lizards reportedly survived. The Mongolian gerbils all expired, apparently due to an equipment failure, said Vladimir Sychev of the Russian Academy of Sciences, according to AFP.

It is unclear at this moment whether it was the harsh environment of weightlessness or equipment failure that caused the mortalities.

Great Britain’s first official astronaut has been picked for a five month mission on ISS in 2015.

10:01 am

Great Britain’s first official astronaut has been picked for a five month mission on ISS in 2015.

Astronaut Michael Foale was born in Britain, but he flew on Mir as an American. Britain meanwhile had banned spending any government money on space exploration in the 1960s, and hadn’t changed that policy until about two years ago. If the reaction to Canadian Chris Hatfield’s ISS mission is any guide, this mission will liven things up a bit for space exploration in the old country.

The Mars rover Opportunity has now traveled farther than any other American rover, including the Apollo 17 rover on the Moon.

The Mars rover Opportunity has now traveled farther than any other American rover, including the Apollo 17 rover on the Moon.

The team operating NASA’s Mars Exploration Rover Opportunity received confirmation in a transmission from Mars today that the rover drove 263 feet (80 meters) on Thursday, bringing Opportunity’s total odometry since landing on Mars in January 2004 to 22.220 statute miles (35.760 kilometers). … The international record for driving distance on another world is still held by the Soviet Union’s remote-controlled Lunokhod 2 rover, which traveled 23 miles (37 kilometers) on the surface of Earth’s moon in 1973.

We have to once again remind ourselves that the roving part of Opportunity’s mission was originally only supposed to last 90 days, not 9 years.

Russia’s Proton rocket successfully put a commercial communications satellite in geosynchronous orbit on Wednesday

9:13 am

The competition heats up: Russia’s Proton rocket successfully put a commercial communications satellite in geosynchronous orbit on Wednesday.

This is the third successful Proton launch this year and the third since a December launch failure. It appears the Russians have ironed out the kinks in the Briz-M upper stage, and are ready to compete with SpaceX’s Falcon 9 rocket. In fact, at the moment they are the only ones who can compete with the Falcon 9, at least when it comes to price.

SpaceX is about to finalize a deal with the Air Force to launch satellites on both its Falcon 9 and Falcon Heavy rockets.

11:18 am

SpaceX is about to finalize a deal with the Air Force to launch satellites on both its Falcon 9 and Falcon Heavy rockets.

For the Dscovr mission, scheduled for late 2014, a Falcon 9 will be used to launch an Earth and space weather satellite to the Sun-Earth Lagrange point L1, a location approximately 930,000 mi. from Earth. The Dscovr program, which will provide warning of space weather events, is a joint effort between the Air Force, NASA and the National Oceanic and Atmospheric Administration. The STP-2 mission, which is targeted for launch on a Falcon Heavy in mid-2015, includes two space vehicles: the Constellation Observing System for Meteorology, Ionosphere and Climate-2 (Cosmic-2), designed to monitor climate behaviors; and the Demonstration and Science Experiments (DSX), which will conduct radiation research. [emphasis mine]

The big story here is that even before it has flown the Falcon Heavy once SpaceX already has a customer for it.

Astronauts today spotted an ammonia coolant leak in ISS’s left-side power truss.

10:51 pm

Astronauts today spotted an ammonia coolant leak in ISS’s left-side power truss.

They are monitoring it, but have so far not made any decision about what to do about it, if anything.

This problem is a perfect illustration of why a flight to Mars is more complicated in terms of engineering than first appears. We might at this time be able to build that interplanetary spaceship (with the emphasis on the word “might”) but could its passengers maintain it millions of miles from Earth? Right now I’d say no. We need to learn how to build an easily repaired and self-sufficient spaceship. ISS is neither. It is also not a very good platform for testing this kind of engineering.

Update: The astronauts on ISS are preparing for a possible spacewalk on Saturday to deal with the problem. More details here.

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

1:04 am

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.
