RobGoldsmith sends word of Interorbital's TubeSat Personal Satellite Kit, which allows anyone to send a half-pound payload to low-earth orbit for $8,000. Your satellite will fly to orbit from Tonga atop an Interorbital Systems NEPTUNE 30 rocket along with 31 other TubeSats. It will function for several weeks, then its orbit will decay and it will burn up in the atmosphere. Interorbital plans to send up a load of 32 TubeSats every month. If you pay in full in advance, you get slotted onto a particular scheduled launch. Here are Interorbital's product page and brochure (PDF).

Matt_dk writes "Armadillo Aerospace conducted two groundbreaking atmospheric test flights this weekend with their 'Mod' vertical-takeoff-vertical-landing rocket, a vehicle familiar to anyone who has followed NASA's Lunar Lander Challenge competitions. Flying from their test facility in Caddo Mills, Texas, Armadillo Aerospace first completed a milestone flight under a NASA contract, using methane fuel and liquid oxygen as propellant. Later that same afternoon, a second successful low-altitude flight was performed using a 'boosted hop' trajectory of the same type that will be used for suborbital flights to space."

Matt_dk writes with this excerpt from Space Fellowship: "Venus Express has charted the first map of Venus' southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with a plate tectonics system and an ocean of water. The map comprises over a thousand individual images, recorded between May 2006 and December 2007. Because Venus is covered in clouds, normal cameras cannot see the surface, but Venus Express used a particular infrared wavelength that can see through them."

Soychemist writes "On the same day that yet another shuttle launch was postponed, SpaceX successfully carried a Malaysian satellite, RazakSAT, into orbit. This is the second successful launch in a row for Elon Musk's space exploration startup. Later this year the company will launch its larger Falcon 9 rocket, which could be used to carry cargo to the International Space Station. RazakSAT was designed by ATSB and carries a high resolution camera. If it is intact, the satellite will take photographs of Earth that could be used to better manage natural resources." Adds xp65: "The satellite was separated from the Falcon 1 about 48 minutes after liftoff at 3:35 GMT (11:35 pm EDT). The orbit is 685 km and 9 degrees inclination. Launch was delayed several times due to a faulty helium valve on the ground and bad weather at the launch site at Kwajalein. This was the fifth flight of the Falcon 1 rocket, with the last two flights being succesful. Later this year the inaugural flight of the larger Falcon 9 rocket is planned from Cape Canaveral."

Matt_dk writes "For the first time in more than a quarter-century, a new space vehicle will begin stacking on a mobile launch platform (MLP) at Kennedy Space Center. The Ares I-X aft skirt, which was mated to a solid fuel segment in the Rotation, Processing and Surge Facility at KSC, rolled over to the 528-foot-tall Vehicle Assembly Building today, where it will be lifted and placed on the MLP in High Bay 3. On that platform, workers will secure the aft booster and continue adding segments of the first stage rocket, the upper stage simulators, the crew module mockup and the launch abort system simulator, taking the vehicle to a height of 327 feet."

"The VX-200 engine is the first flight-like prototype of the VASIMR® propulsion system, a new high-power plasma-based rocket, initially studied by NASA and now being developed privately by Ad Astra. VASIMR® engines could enable space operations far more efficiently than today's chemical rockets and ultimately they could also greatly speed up robotic and human transit times for missions to Mars and beyond."

coondoggie writes "While NASA's commercial partners such as SpaceX and Orbital have made steady progress in developing space cargo transportation technology, they have recently fallen behind their development schedules. Combine that with the fact that the most critical steps lie ahead, including successfully launching new vehicles and completing integration with the space station, and you have a hole that will be tough to climb out of. Those were the two main conclusions of a Government Accountability Office report (PDF) on the status of the commercial space world this week. The GAO went on to say that after the planned retirement of the space shuttle in 2010, NASA will face a cargo resupply shortfall for the International Space Station of approximately 40 metric tons between 2010 and 2015." Speaking of SpaceX, reader Matt_dk sends along an update on the company's Falcon 9 flight efforts. "Six of the nine first stage flight engines have completed acceptance testing and all nine flight engines are on schedule to complete acceptance testing by mid-July."

Matt_dk writes "In November 2008, Caroline Moore, a 14-year-old student from upstate New York, discovered a supernova in a nearby galaxy, making her the youngest person ever to do so. Additional observations determined that the object, called SN 2008ha, is a new type of stellar explosion, 1000 times more powerful than a nova but 1000 times less powerful than a supernova. Astronomers say that it may be the weakest supernova ever seen."

Matt_dk writes "Astronomers have found more than 300 alien (extrasolar) worlds so far. Most of these are gas giants like Jupiter, and are either too hot (too close to their star) or too cold (too far away) to support life as we know it. Sometime in the near future, however, astronomers will probably find one that's just right — a planet with a solid surface that's the right distance for a temperature that allows liquid water — an essential ingredient in the recipe for life. Now scientists looking back at Earth with the Deep Impact/EPOXI mission have developed a method to indicate whether Earth-like extrasolar worlds have oceans."

DSG2 sends in an ESA press release which reads in part: "This afternoon, the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite developed by the European Space Agency was lofted into a near-Sun-synchronous, low Earth orbit by a Rockot launcher lifting off from the Plesetsk cosmodrome in northern Russia. GOCE is the first of a new family of ESA satellites designed to study our planet and its environment in order to enhance our knowledge and understanding of Earth-system processes and their evolution, to enable us to address the challenges of global climate change. In particular, GOCE will measure the minute differences in the Earth's gravity field around the globe." One consequence of mapping the planet's geoid in finer detail is that ocean currents can be limned more accurately. This BBC article from 2007 goes into some detail about this application.

The scientists found unexpectedly large amounts of methane in the atmosphere, and also discovered that the atmosphere is hotter than the surface by about 40 degrees, although it still only reaches a frigid minus 180 degrees Celsius. These properties of Pluto's atmosphere may be due to the presence of pure methane patches or of a methane-rich layer covering the dwarf planet's surface."

Matt_dk sends in a quote from a story at NASA: "The first gamma-ray burst to be seen in high-resolution from NASA's Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest motions and the highest-energy initial emissions ever seen. ... Gamma-ray bursts are the universe's most luminous explosions. Astronomers believe most occur when exotic massive stars run out of nuclear fuel. As a star's core collapses into a black hole, jets of material — powered by processes not yet fully understood — blast outward at nearly the speed of light. The jets bore all the way through the collapsing star and continue into space, where they interact with gas previously shed by the star and generate bright afterglows that fade with time. ...Fermi team members calculated that the blast exceeded the power of approximately 9,000 ordinary supernovae, if the energy was emitted equally in all directions."

Matt_dk writes with news that scientists have detected water in a galaxy 11.5 billion light-years from Earth. Evidence came in the form of emissions from water masers around a quasar at the center of the galaxy. Detection at such a large distance was made possible by a closer, intervening galaxy which acted as a gravitational lens. "'We were only able to discover this distant water with the help of the gravitational lens,' said Violette Impellizzeri, an astronomer with the Max-Planck Institute for Radioastronomy (MPIfR) in Bonn, Germany. 'This cosmic telescope reduced the amount of time needed to detect the water by a factor of about 1,000,' she added. The astronomers first detected the water signal with the Effelsberg telescope. They then turned to the VLA's sharper imaging capability to confirm that it was indeed coming from the distant galaxy. The gravitational lens produces not one, but four images of MG J0414+0534 as seen from Earth. Using the VLA, the scientists found the specific frequency attributable to the water masers in the two brightest of the four lensed images. The other two lensed images, they said, are too faint for detecting the water signal. The radio frequency emitted by the water molecules was Doppler shifted by the expansion of the Universe from 22.2 GHz to 6.1 GHz."

Toren Altair brings news that NASA and the Ad Astra Rocket Company finalized a Space Act Agreement earlier this week to test the Variable Specific Impulse Magnetoplasma Rocket (VASIMR) on the International Space Station. The agreement hinges on a series of requirements for the thruster's performance and efficiency in ground-based tests. "The primary technical objective of the project is to operate the VASIMR VF-200 engine at power levels up to 200 kW. Engine operation will be restricted to pulses of up to 10 minutes at this power level. Energy for these high-power operations will be provided by a battery system trickle-charged by the ISS power system. These tests will mark the first time that a high-power, steady-state electric thruster will be used as part of a manned spacecraft." Reader clarkes1 points out related news of a runway trial for Virgin Galactic's WhiteKnightTwo, the mothership that is designed to carry SpaceShipTwo from the ground to 50,000 feet. A very brief video shows the oddly-shaped plane moving down a runway under its own power.
