Sunjammer, NASA’s next solar sail experiment.
Though the article headline focuses on the addition of space weather instruments to this solar sail, the article says very little about those instruments. One, Swan, is described as a “wind instrument”, which probably means it would study the solar wind. The other instrument would study the Earth’s magnetic field. Both instruments are needed to track the effect of the Sun on local space weather, since the one satellite we have to do this, Ace, is now more than a decade past its expiration date.

Solar Impulse has completed the second leg of its journey to fly across the United States powered only by the sun.
Solar Impulse has completed the second leg of its journey to fly across the United States powered only by the sun.
The Solar Impulse has broken its own record for the longest distance flight of a solar-powered aircraft following the second leg of its journey across the USA. Solar Impulse touched down in Texas at 1:08 a.m. local time after a flight of 18 hours 21 minutes having covered at least 868 miles (1,397 km). Two different distances have been reported for the flight. The Solar Impulse website says the flight “amounted” to 868 miles (1,397 km). However, according to a Phys.org report, Solar Impulse covered a distance of 1,541 km (which it rounds to 950 miles, though this is not the precise conversion).
It is thought the two distances exist because the plane actually lost ground during part of its flight due to headwinds.

I note this to give some context to what SpaceX will do with Falcon 9 this year. SpaceX has just updated its launch manifest schedule, and if the American company does what it says, it should have at least six more Falcon 9 flights this year, for a total of seven.
Should these predicted launches all take place, it will clearly demonstrate that SpaceX has grabbed a significant share of the launch market, but that the Russians are also holding their own.
Note also that the updated launch manifest still includes the first test flight of Falcon Heavy in 2013. Very interesting.
Update: The Russians are also preparing to launch their new Angara rocket family, which will replace their older rockets and allow them to launch from their new spaceport.

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

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.

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.
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.
